Although early stimulation supports neurobehavior, structured, gestational age–specific protocols are limited in India, where clinical variation and inconsistent caregiver integration persist. The objective of the study is to develop a context-appropriate, week-wise stimulation protocol for preterm infants (26–40 weeks postmenstrual age) by triangulating research evidence, therapist-informed practices, and maternal readiness. Methods: A sequential mixed methods approach was adopted. Systematic review of randomized control trials (2010–2023) charted stimulation timing, dosage and mode. Semi-structured interviews with NICU physiotherapists (n = 17) investigated decision-making and feasibility. Phenomenological interviews with mothers (n = 12) examined readiness and perceived capacity. Joint display analysis was used to integrate findings and construct a layered stimulation protocol. Results: Core modalities such as kangaroo care, auditory stimulation (maternal voice), olfactory input, and oromotor stimulation were supported across data sources and included by gestational progression. Notably, nesting/positioning and Yakson touch, absent in trial evidence emerged as critical therapist-led practices, with high maternal acceptability. Modalities such as visual, vestibular, and multisensory input were phased in from 31–34 weeks based on infant readiness and caregiver confidence. Conclusion: The resulting protocol provides Low-Middle Income country (LMIC) feasible week-specific, role-sensitive, developmentally layered stimulation model. By aligning evidence, practice, and experience, it offers a feasible, family-integrated habilitation approach for resource-constrained NICUs. Infant premature Neonatal Intensive Care Units early stimulation India Mixed methods Research Contributions to the literature This study presents a gestational age–specific early stimulation protocol (26–40 weeks) tailored for Indian NICUs using triangulated input from literature, therapists, and mothers. In contrast to the SENSE program, which is expert-driven and developed in high-resource contexts, this protocol integrates maternal readiness and therapist-informed feasibility into intervention timing and delivery roles. The protocol assigns week-wise, modality-specific responsibility to therapists or parents, grounded in gestational maturity and clinical capacity. It incorporates contextual flexibility and cultural alignment, addressing gaps in LMIC implementation. A joint display triangulation framework ensures that each component reflects both evidence and ground-level practice. Introduction Premature delivery continues to be one of the greatest public health problems and a major cause of neonatal illness and death. All over the world there are almost 15 million premature babies born every year and India accounts for approximately 3.5 million of them, the highest country burden in the world ( 1 – 3 ). Despite enhanced clinical management and facilities, an increased survival rate in Indian tertiary neonatal intensive care units (NICUs) remains a challenge in the face of a similar increase in late neurodevelopmental handicaps, most notably in infants born prior to 34 weeks' gestation( 4 ). Such impairments, including delays in motor skills, intellectual impairment, and sensory integration disorder, not only rely on biological immaturity and comorbidities but also upon the absence of systemic, developmentally based sensory experience during hospitalization( 5 – 7 ). The late gestational period (26–40 weeks postmenstrual age) is a period of unprecedented importance for brain development. Appropriate modulated sensory input e.g., touch, voice, olfactory, and oromotor stimulation can be organizing in a positive way during this period, favouring neurobehavioral organization, autonomic function, and functional connectivity( 8 , 9 ). All these interventions are Synactive Theory of Development based, which highlights scaffolding the developing behavioral systems of the infant through individualized and sequenced input( 10 , 11 ). Meanwhile, Family Integrated Care (FICare) and other models encourage the involvement of parents in the NICU both as a therapeutic support and a support system for their emotions( 12 , 13 ). Yet, formal practice of early sensory stimulation in Indian NICUs is still limited. Practices of stimulation are frequently determined by therapist judgment, infrequently prescribed according to established gestational age, and variably introduced to caregivers. In a recent national audit in india, there was considerable variation in NICUs regarding stimulation routines and parent involvement, as well as delivery by staff( 14 , 15 ). Although mothers are becoming more visible in NICU environments, especially in state-funded family-centered care units, their role in early habilitative procedures is typically unorganized, intuitive, and guided by no professional expertise. The result is a disjointed care environment in which stimulation is either underutilized, over-used, or presented without consideration for the infant's neurodevelopmental status.( 16 , 17 ). At a global level, practices like SENSE (Supporting and Enhancing NICU Sensory Experiences) have come up as systematic, gestational age–specific models of sensory support for preterm infants( 18 ). These high-resource-based programs provide week-wise elaborate stimulation plans and define roles for caregivers and professionals. Yet, their applicability in India is constrained by several contextual barriers such as heavy patient loads, variable access to trained therapists, restricted staff-parent ratios, and a lack of standardized parent education streams. Further, cultural practices, hospital facilities, and caregiver expectations are highly variable across Indian NICUs, such that direct importation of such frameworks is difficult.( 12 , 15 , 19 , 20 ). Low and Middle Income Countries (LMIC) like India needs as a priority is a developmentally sequenced, role-sensitive, and culturally flexible protocol for early stimulation. As opposed to rehabilitation programs geared for post-discharge intervention, early habilitation in the NICU focuses on prevention and facilitation of optimal neurodevelopment by sensory and environmental enrichment prior to term age( 8 , 21 ). Such a protocol would detail with precision which sensory modalities to employ, at what gestational age, in what clinical conditions, and by whom, parent or therapist, or both. It would have to consider not only the empirical evidence that happens to be available but also the demands of clinical practice and the readiness of caregivers to engage in effective therapeutic interaction. This research sought to create a gestational age–specific early stimulation protocol for preterm infants in neonatal intensive care units (NICUs) through the combination of three divergent knowledge sources: structured evidence from published literature, clinical experience from physiotherapists in NICUs, and everyday caregiving experiences from mothers of preterm infants. The goal was to create a week-by-week, developmentally targeted protocol that not only delineates what interventions are suitable for which gestational age group, but also when, how, and by whom they ought to be given. The research aimed to frame these interventions within the realities of care provision in low- and middle-income country (LMIC) NICU environments, specifically in India. Methods Study Design and Rationale This study employed a mixed methods design, integrating both qualitative and structured review components through a formal triangulation process and joint display analysis. Specifically, the study followed a sequential exploratory mixed methods framework. The process started with a systematic review of neonatal stimulation interventions to explore gestational timing, delivery agents, and procedural parameters of evidence-based practice. This was supplemented by two qualitative strands: (i) physiotherapist NICU interviews to record clinical feasibility and implementation logic, and (ii) phenomenological mother interviews to investigate emotional readiness, caregiving behaviors, and perceived barriers to participation. The mixed-methods approach was justified methodologically by the multicollinearity of the research question that called for the intersection of empirical data, experiential insight, and caregiver input to yield construct validity and implementation acceptability. Instead of privileging one type of data over another, the design favoured equal weighting among all three sources to inform final protocol decisions. The process culminated in an integration phase using joint display matrices, which allowed direct comparison of findings from the systematic review, therapist interviews, and maternal interviews for each stimulation modality. These matrices facilitated the classification of each intervention-week pairing as convergent, conditional, or divergent and informed the final structure and delivery recommendations of the protocol. The research was performed according to the GRAMMS (Good Reporting of a Mixed Methods Study) guidelines. Every part followed method-specific criteria, such as PRISMA for the systematic review and COREQ for the qualitative parts. The triangulated synthesis was the core analytic product of this design, generating the meta-inferences required to transition into protocol development. Sequence of study methods : Component 1 - Systematic Review: Mapping of Intervention Characteristics The initial phase was a systematic review, set to not assess the clinical effectiveness of stimulation interventions but to record their structural and developmental parameters. The primary aim was to determine when, how, and by whom various interventions were administered in ongoing randomized trials. Search databases were PubMed, Scopus and Proquest, and articles between 2010 and 2023 were included. The inclusion criteria were RCTs and quasi-experimental studies in NICUs that reported stimulation interventions for preterm infants between 26 to 40 weeks' gestation. Studies without gestational timing or implementation details were excluded. Data extracted included intervention modality (e.g., tactile, auditory, oromotor), gestational week of initiation and cessation, session duration and frequency, and delivery agent (parent, nurse, therapist). A structured data extraction sheet was used in Microsoft Excel by three independent reviewers (AJR, MS, KS) and the conflicts was resolved by another researcher (VK). The extracted data were synthesized into a gestational age-by-modality matrix, which served as the foundation for subsequent triangulation. This mapping allowed visualization of which interventions were structurally feasible across developmental stages, independent of reported outcomes. Component 2 – Therapist Interviews: Clinical Feasibility and Implementation Patterns In the second phase, semi-structured interviews were conducted with physiotherapists working in NICUs across India to understand how stimulation interventions are currently delivered, modified, or withheld in routine practice. A phenomenological lens was adopted to capture therapists’ lived clinical reasoning and the implicit criteria guiding their practice. Purposive and snowball sampling yielded 16 participants from a range of institutional contexts, including public and private tertiary hospitals across Tamil Nadu, Delhi, Hyderabad, and Bengaluru. Eligibility demanded two years of experience specific to NICU. Telephone interviews were held in English and ranged from 45 to 60 minutes. A semi-structured interview guide, constructed following literature review and consultation with experts, addressed intervention sequencing, therapist-only interventions, parent training techniques, and decision-making thresholds on the basis of infant readiness. Telephone interviews were recorded with participants' consent, transcribed verbatim, and analyzed with Braun and Clarke's six-phase reflexive thematic analysis. Coding was conducted manually in Excel by two independent researchers, with themes refined iteratively. Final themes included "routine practices by gestational week," "barriers to parent involvement," "infant stress cue observation," and "therapist discretion versus protocol-driven care." Field notes and member checks enhanced credibility. Thematic saturation was used as the stopping criterion. Findings were organized into a therapist feasibility matrix aligned by modality and GA. ( 22 ) Component 3 – Maternal Interviews: Readiness and Acceptability The third phase involved a descriptive phenomenological study aimed at capturing mothers’ lived experiences, emotional responses, and perceived capability to engage in NICU-based stimulation. Twelve mothers of preterm infants (GA 28–37 weeks), recruited from NICU follow-up clinics, participated in face-to-face interviews conducted in Tamil within the hospital’s mother-infant areas. Interviews coincided with skin-to-skin care hours to enhance contextual recall. Eligibility demanded recent NICU experience, continued caregiving duty, and informed consent. A semi-structured interview guide probed maternal attitudes towards bonding, caregiving behaviors (e.g., holding, talking, feeding), knowledge of stimulation practice, perceived risks, and barriers to participation. Interviews were audio-recorded, transcribed verbatim, and translated into English. A phenomenological reduction technique was applied to identify invariant meaning units that reflected readiness, willingness, fear, instinctive caregiving, and information gaps. Two researchers independently analyzed the transcripts; interpretive alignment was achieved through consensus discussions. The resulting themes were synthesized into a maternal readiness matrix by modality and gestational age, highlighting which interventions mothers practiced intuitively, which required structured introduction, and which were viewed as exclusive to therapists. Triangulation and Joint Display Analysis Following the independent analysis of each data stream, the fourth phase involved triangulation using joint display analysis. The goal of this phase was to integrate evidence from the systematic review, therapist practice, and maternal readiness into a unified framework that could inform a gestationally appropriate stimulation protocol. The triangulation proceeded in five stages. First, a raw triangulation matrix was constructed for each modality, displaying unaltered data excerpts from all three sources. This ensured analytic transparency and preserved the integrity of each data stream. Second, an interpretive coding step was applied, where each modality-week pair was classified as either convergent (✔), conditional (⚠), or excluded (✖), based on alignment across sources. Conditional codes reflected either the need for therapist supervision, maternal training, or medical stability. Third, a comprehensive joint display matrix was developed, listing each intervention modality, its evidence-based timing and delivery structure, therapist feasibility, maternal acceptability, triangulated judgment, and final protocol decision. Fourth, a gestational week x modality matrix was created, color-coded to indicate convergence and conditionality across weeks 26 to 40. This table translated the protocol into operation and graphically showed the evolution of some interventions (e.g., tactile to tactile-kinesthetic; therapist-to-parent) across time. Lastly, a barrier–facilitator matrix was built on cross-cutting qualitative themes, siting how emotional, physical, or informational barriers affected feasibility, and illuminating enabling practices like peer support and bedside training. Data Integration Team and Bias Mitigation Triangulation and integration were conducted by a three-member analytic team (AJR, MS, KS). Two researchers (AJR, MS) who had led the original coding of therapist and maternal interviews conducted the initial convergence coding. A third researcher (KS), not involved in primary data collection, reviewed all raw and interpreted matrices to challenge potential confirmation bias. All convergence decisions were recorded in an audit log with justifications. Reflexive memos were maintained throughout integration, documenting interpretive shifts and rationale for classification. Disagreements in convergence codes were resolved through consensus meetings, ensuring consistency in methodological logic. Manual coding and Excel-based joint display construction were deliberately chosen to allow full visibility into the data transformation process and to avoid abstraction through software automation. This enhanced methodological traceability and transparency in protocol development.

I wanted to help him do it more.” Respiratory PNF Risk of bradycardia or overstimulation Works well if monitored carefully; requires expert handling “We have to be careful; only after full stabilization.” “They never mentioned that part to me.” Auditory (Voice) NICU noise can compete; no structure Natural maternal behavior; highly emotional and bonding “We encourage mother’s voice over any recorded music.” “I sing to him every time I’m allowed inside.” Olfaction Hygiene concerns (e.g., cloth contamination) Breast pad or mother cloth near incubator is easy, low risk “Breast milk-smeared cloth near nose works well.” “I left my scarf near her crib, they said it helps.” Visual Risk of overstimulation if started early Face regard is natural and soothing “We use face-to-face interaction from 32 weeks, not toys.” “I saw her look at me and blink slowly, it felt like a response.” Gustatory Unclear protocols for taste exposure Prepares for feeding; mothers highly motivated “If oral feeds are delayed, we use breastmilk swabs.” “He licked my finger, I was delighted.” Vestibular Medical contraindications in very preterm Done informally during KMC or cradling “Rocking during KMC counts as vestibular, it’s safe if gentle.” “I have not performed that.” Multisensory Layered Risk of overstimulation if done too early or too fast Mothers already combining modalities (KMC + voice); layering can be taught gradually “We layer touch + voice + scent from 32–33 weeks onwards.” “I held him, spoke to him, and he smelled my scent. it felt like home to him.” * KMC – Kangaroo Mother Care, PNF – Proprioceptive Neuromuscular Facilitation Purpose: Captures key barriers , facilitators , and contextual enablers reported by therapists and mothers for each intervention RESULTS This phase aimed to triangulate findings from three independent sources, systematic review, NICU therapist interviews, and maternal readiness interviews to determine feasible, developmentally appropriate, and context-sensitive early stimulation components for preterm infants across gestational age (GA) windows. The triangulation process was structured sequentially across four integrated tables, described below. 3.1 Intervention–Modality Mapping from Review A modality × gestational age mapping was derived from the systematic review. It identified the onset and continuity of 13 early stimulation interventions from 26 to 40 weeks GA. The review-supported inclusion of nesting, skin-to-skin care (KMC), auditory stimulation (maternal voice), and olfactory stimulation from as early as 26–28 weeks GA. Other modalities such as tactile-kinesthetic input, vestibular stimulation, oromotor support, and visual stimulation were found to be more appropriate from 31–34 weeks onward. Reflex locomotion and respiratory PNF were mapped to 28–37 weeks and 30–40 weeks respectively, but were consistently therapist-led. The summarized data are presented in supplementary file 1. 3.2 Therapist-Informed Practice Synthesis Semi-structured interviews with NICU physiotherapists revealed both routinely used and cautiously applied interventions. Nesting, KMC, auditory stimulation, positioning, and environmental modulation were reported as standard care. Tactile stimulation (Yakson touch), respiratory PNF, and proprioceptive techniques were selectively applied after medical stabilization, particularly in infants above 28–30 weeks GA. Reflex locomotion was used infrequently and only by select therapists. Therapists emphasized the need for strict stress cue observation, hygiene protocols, and maternal education prior to involving caregivers in stimulation tasks. The insights gathered from the interviews of the therapist are tabulated in supplementary file 1. 3.3 Maternal Readiness Analysis Mothers demonstrated high readiness and emotional commitment to participating in nesting, KMC, auditory (talking/singing), and olfactory stimulation (breastmilk scent or cloth placement). Moderate readiness was noted for tactile-kinesthetic involvement, which some mothers had performed informally. Mothers expressed eagerness to support feeding transitions through oromotor cues but required training and reassurance. Visual and vestibular cues were often practiced instinctively, though not structured. Clinical interventions such as respiratory PNF and reflex locomotion were unfamiliar and perceived as therapist-only domains. Maternal perspectives and practice in NICU are enclosed in supplementary file 1. 3.4 Raw Triangulation Matrix A full raw triangulation table was developed, documenting statements across all modalities from the three sources without interpretation as depicted in Table 1 . This side-by-side comparison clarified where evidence, clinical feasibility, and caregiver readiness converged or diverged. This served as the foundation for analytic convergence. 3.5 Triangulation Justification Table Based on the raw matrix, a triangulation judgment was assigned per modality: ✔ (convergent), ⚠ (conditional), or ✖ (excluded). The matrix is displayed in Table 2 . Most interventions were found to be convergent (e.g., nesting, KMC, auditory, olfaction, visual, gustatory, vestibular). Conditional inclusion was assigned to therapist-dependent modalities (tactile-kinesthetic, oromotor, respiratory PNF, multisensory layering, reflex locomotion), typically requiring gestational maturity and maternal training. No interventions were excluded entirely, though some were restricted to therapist-only application. 3.6 Joint Display Triangulation Matrix A comprehensive joint display matrix was constructed to integrate findings across all three sources and is enlisted in Table 3 and Table 4 . The final protocol decisions were guided by convergence status. For instance, nesting and KMC were included from 26 weeks with progressive parent-led delivery. Oromotor and vestibular stimulation were introduced from 28–34 weeks with therapist supervision. Reflex locomotion and respiratory PNF were retained only for specialized therapist delivery. 3.7 Week × Modality Triangulation Matrix The final synthesis was captured in a week-wise modality matrix from 26 to 40 weeks GA. Each cell was color-coded (✔ green, ⚠ yellow, ✖ red) to reflect the triangulated feasibility. This table operationalized the protocol by matching gestational timing, modality readiness, and safe delivery roles (therapist or parent). Interventions such as Yakson touch were phased out by 30 weeks, while multisensory layering began from 31 weeks with gradual intensification. By 37–40 weeks, most modalities were implemented either independently by mothers or jointly with therapist support. The week wise modality triangulation matrix is shown in Table 5 . 3.8 Barrier–Feasibility–Facilitator Matrix A qualitative synthesis was constructed to contextualize real-world implementation challenges and enablers which summarized in Table 6 . Barriers were physical distress during KMC, concern about injuring the baby during touch care, or unfamiliarity with structured modalities such as Yakson touch or reflex locomotion. These facilitators included therapist demonstrations, support of peers, and natural mothering behaviors (e.g., rocking, talking, eye contact). Quotes from mothers and therapists supported the themes and these practices to reinforce the value of progressive education and confidence building. Discussion This study developed a gestational age–specific, stimulation protocol for preterm infants in NICU by triangulating three diverse data sources: structured literature from randomized controlled trials, experiential knowledge from neonatal physiotherapists, and caregiving insights from mothers of preterm infants. Using joint display analysis, the study constructed a developmentally sequenced framework of stimulation interventions mapped across 26 to 40 weeks postmenstrual age (PMA). This protocol was uniquely informed not only by clinical evidence but by real-world practice constraints and maternal emotional readiness, making it both implementable and family-integrated. Four interventions, oromotor simulation, kangaroo mother care (KMC), auditory stimulation (mainly maternal voice), and olfactory stimulation were totally convergent in all three data sources from as early as 26 weeks PMA. These interventions were evidenced by several RCTs as providing benefits for improving self-regulation, autonomic stability, and bonding( 23 , 24 ). Therapists indicated these as standard practices, frequently utilized to commence developmental care in ventilated or medically fragile infants Maternal interviews confirmed high instinctive participation and emotional attachment to these modalities particularly KMC, which many mothers described as pivotal in "feeling like a mother again."( 25 , 26 ) From a theoretical standpoint, this convergence aligns with Als’ Synactive Theory of Development, which emphasizes the importance of supporting autonomic and self-regulatory subsystems before introducing active engagement( 27 ). These foundational interventions provide proprioceptive containment (nesting), tactile and thermal input (KMC), auditory familiarity (voice), and olfactory comfort (maternal scent), all crucial for promoting neurobehavioral organization in early gestational windows. The inclusion of these from 26 weeks onward, as seen in the Week × Modality Matrix, validates their role as non-negotiable pillars of early habilitation. Several modalities Yakson touch, tactile-kinesthetic stimulation, oromotor stimulation, reflex locomotion, respiratory PNF, gustatory stimulation, visual engagement, vestibular input, and multisensory layering were included conditionally, based on gestational readiness, safety thresholds, or caregiver training needs. Yakson touch, supported in literature for calming effects between 26–30 weeks, was practiced cautiously by therapists but largely unknown to mothers. Although mothers observed gentle touch techniques being used, they did not perceive them as structured interventions.( 28 – 30 ) Hence, this modality was included as therapist-only until 30 weeks, after which other forms of tactile stimulation could be layered in. Similar findings have been reported in East Asian NICU contexts, where culturally acceptable massage methods are introduced late due to fear of overhandling( 28 , 31 , 32 ). Tactile-kinesthetic stimulation showed convergence only after 31 weeks, consistent with literature suggesting that muscle tone, arousal modulation, and tolerance for passive movement improve as the infant matures( 33 , 34 ). While therapists reported performing passive movement routines post-stabilization, mothers, though unaware of the technique, often touched or moved their baby’s limbs instinctively. The conditional convergence of this modality suggests it is well-suited for graduated parent involvement, under therapist supervision. Oromotor stimulation was inconsistently practiced by therapists due to clinical constraints, but highly resonant for mothers. Many linked their baby’s first sucking reflex or smile to a turning point in their NICU journey. Literature supports the use of oromotor stimulation from 29–30 weeks onward for facilitating non-nutritive sucking and feeding readiness( 35 , 36 ). The inclusion of this modality as therapist-led from 29 weeks addresses both neurodevelopmental benefit and maternal emotional significance. Reflex locomotion therapy and respiratory PNF remained therapist-exclusive, due to their technical complexity and limited caregiver awareness( 37 ). Respiratory PNF, while supported in routine practice and respiratory efficiency, were reported rarely in the literature. Their inclusion in the protocol as conditionally, therapist-only after stabilization tells them they are valued without risking unsafe delegation. Gustatory, visual, and vestibular modalities became appropriate only subsequent to 32–34 weeks, coinciding with the development of oral readiness, light tracking, and vestibular tolerance. Mothers were already doing so informally speaking to their baby during feeding, swaying during KMC, or reacting to visual stimuli, emphasizing how natural caregiving activities can become bases for organized stimulation. Literature supports this timing, indicating that vestibular and visual inputs should be introduced cautiously to avoid overstimulation and dysautonomia in the fragile preterm brain( 38 – 41 ). A key insight from the triangulation was the natural occurrence of multisensory layering particularly during KMC where mothers unknowingly combined voice, touch, scent, and sometimes movement. Although neither the literature nor therapists explicitly structured these combinations, the presence of such layering in maternal narratives suggests an opportunity to formalize instinctive caregiving into a scaffolded multisensory progression from 31 weeks onward. This supports the theoretical model of graded sensory integration, wherein sensory modalities are introduced in overlapping, developmentally sequenced layers.( 42 – 44 ) Evidence indicates that early intervention programs that prioritize parent-child collaboration demonstrate superior developmental outcomes compared to those solely focused on the infant, emphasizing the importance of engaging and supporting parents in the intervention process ( 45 ). Unlike most developmental care guidelines, which treat stimulation as modality-specific or outcome-based, this study contributes a temporal logic to NICU habilitation. The Week × Modality Matrix clearly illustrates how some interventions (e.g., Yakson touch) phase out by 30 weeks, while others (e.g., tactile-kinesthetic) phase in at that same window. Similarly, delivery responsibility transitions from therapist-only to parent-led, reflecting not only infant developmental readiness but maternal confidence and exposure.( 46 , 47 ) Interventions that focus on promoting social-emotional development by stimulating the limbic system through sensory input can be particularly beneficial for preterm infants( 44 ). This transitional structure mirrors models of scaffolded caregiving, where early weeks are therapist-dominated and parents gradually assume greater roles with support. This protocol operationalizes this through clear color-coded matrices, setting a benchmark for developmental appropriateness, safety, and participatory care. The developmental needs of preterm infants must be balanced with the parents' readiness to provide skin-to-skin care, which can be influenced by their perception and interpretation of the infant's cues.( 48 ) Ultimately, the matrices provide a unique visualization of temporal transitions within a sensory-motor domain, contributing to the practical translation of theoretical models for dynamic parent-infant interaction in the NICU. By aligning therapeutic interventions with the infant's gestational age and neurological development, the "sequential multimodal treatment model" offers a structured approach to supplemental stimulation, potentially improving behavioral organization in premature infants ( 49 ). A defining feature of this study is how often mothers were already practicing the essence of structured interventions - voice, eye contact, movement, scent,without formal training. Rather than framing parental behaviors as unstructured or deficient, this protocol affirms them as emotionally grounded foundations for habilitation. By layering professional oversight on top of caregiving instincts, the protocol fosters co-regulation rather than supervision, empowerment rather than instruction ( 50 ). These insights are especially relevant for LMIC NICU settings, where overburdened therapists, understaffed wards, and high parental involvement necessitate flexible, low-cost, developmentally sound intervention models. This study addresses a key implementation gap: how to balance clinical standards with parental capacities without adding complexity or fear. Few existing protocols offer a week-by-week, modality-specific, and role-assigned approach to stimulation in NICUs. While programs such as NIDCAP or FICare emphasize developmental care and parent involvement, they often lack gestational specificity or modality sequencing for early preterm infants. Similarly, most early intervention studies focus on post-discharge outcomes or single-modality interventions. ( 23 , 45 , 51 – 53 ) This study contributes a novel, integrative protocol tailored to NICU timelines, grounded in structured evidence but co-designed with therapists and parents, a model that bridges evidence, practice, and lived experience. Among the interesting results from the triangulation was the lack of positioning or nesting-related interventions across the reviewed RCTs, despite its universal endorsement by therapists and spontaneous adoption by mothers. This disparity is typical of a limitation in trial literature within neonatal care, which tends to focus on quantifiable sensory outcomes (e.g., weight gain, neurobehavioral scores) while neglecting underlying interventions that allow infants to tolerate and receive benefit from stimulation in the first place. Nesting, though rarely framed as a primary intervention in trials, is a critical precondition for autonomic regulation and is embedded in both the Synactive Theory and NIDCAP frameworks. Its strong presence in therapist narratives suggests that practice wisdom may sometimes outpace literature in recognizing the regulatory value of low-risk, easily taught interventions, especially when treating infants at 26–30 weeks PMA ( 52 , 54 ). Finally, while this study proposes a novel, layered, GA-specific protocol for stimulation in NICUs, it is important to position this contribution within the broader context of existing structured programs. The SENSE program, established in high-income environments, is a gold-standard, evidence-based practice that offers week-by-week, sensory stimulation activities to preterm infants. Its use, however, necessitates extensive staff education, formal caregiver education modules, and ongoing material support, all resources in short supply in LMIC NICUs ( 55 , 56 ). Additionally, SENSE was not originally designed with cultural tailoring, parent-led delegation, or minimal-resource flexibility in mind. In contrast, the protocol developed through this study addresses these gaps by embedding contextual feasibility, cultural acceptability, and staged parental involvement as core components. It maintains the age-based developmental rationale of stimulation but enables flexible integration into the structural and cultural practices of Indian NICUs. This makes it a practical, scalable addition to formal sensory programs that are not yet possible in settings with limited resources. Implications This study offers several important implications for neonatal care delivery, policy, and research in low-resource settings. First, by integrating evidence, clinical reasoning, and caregiver experience into a unified, week-specific protocol, it demonstrates how developmental care can be both structured and participatory. The protocol does not prescribe isolated interventions but instead organizes them as an adaptive, layered habilitation pathway shifting responsibility from therapist to parent as the infant matures, and enabling scalable delegation in overstretched healthcare systems. Second, the protocol explicitly addresses therapist-parent dynamics in NICU care. It provides a roadmap for training, supervision, and confidence-building strategies that reflect the gradual transition of stimulation roles. This supports models such as Family Integrated Care (FICare), but advances them by assigning responsibility not only by individual preference but also by developmental readiness, modality complexity, and safety threshold. Third, by embedding maternal readiness into protocol development, the study moves beyond tokenistic “parent involvement” and creates conditions for genuine parental empowerment. It legitimates instinctual behaviors such as voice, rocking, face regard and directs them into organized, evidence-based practice. By doing so, it fortifies the therapeutic relationship between parent and clinician, which has been demonstrated to have favorable effects on both neurodevelopment and parental mental health. Finally, the methodological approach specifically the triangulation and display of the joint Week × Modality Matrix provides a model for replication by researchers and policymakers interested in adapting global evidence to developmentally appropriate, culturally viable neonatal interventions. Limitations Several limitations warrant consideration. While the systematic review mapped gestational timing and delivery structure of stimulation modalities, it did not assess intervention efficacy or rank outcomes, which limits the ability to prioritize interventions based solely on impact metrics. Second, the review included only English-language trials, potentially excluding relevant regional or non-indexed evidence. In the qualitative components, the sample of therapists though geographically diverse was limited to physiotherapists, excluding views of occupational therapists, speech therapists, nurses, or neonatologists who may influence care delivery patterns. Similarly, mothers interviewed were those who had stable, recovering preterm infants and may represent a more engaged or confident subgroup; those with critically ill neonates or early loss were not included. In the integration phase, although the triangulation coding was done collaboratively and reviewed independently, interpretive bias cannot be fully ruled out, especially in conditional classification zones. In addition, the protocol has not yet been piloted for implementation fidelity, neurodevelopmental effects, or caregiver burden. Thus, generalizability is confined to the protocol design stage. Recommendations and Future Directions Future studies would need to look at potential testing of this protocol within real live NICU environments for determining feasibility, compliance, and clinical impact. Implementation research would examine the way delegation from therapist to parent develops in real-life practice environments, and what kind of training or supervision infrastructure is necessary in order to enable effective delegation of this task. The inclusion of speech-language pathologists, developmental pediatricians, and neonatal nurses from cross-disciplinary backgrounds in subsequent editions would ensure that protocols for stimulation are being applied across domains of care, particularly given that feeding, sensory regulation, and postural control overlap. Protocol adaptation into visual, multilingual, and low-literacy versions for bedside parental application is another essential next step, with usability testing. Outcomes should not only measure infant neurodevelopmental parameters but also maternal confidence, caregiver satisfaction, and unit-level feasibility. In conclusion, although this investigation targets pre-discharge habilitation, future studies need to examine continuity of stimulation after discharge, to ensure an unbroken continuation into early intervention or home-based care programs. Conclusion This research provides a new, developmentally appropriate, and context-sensitive stimulation protocol for preterm NICU infants, co-developed with therapists and mothers using a systematic triangulation approach. By stacking interventions by gestational age, clinical stability, and caregiver readiness, the protocol links empirical evidence, clinical feasibility, and emotional resonance. Compared to generic stimulation models, this protocol defines what, when, and by whom thus establishing a scaffolded habilitation model that is grounded in the realities of LMIC NICUs. It enables caregivers, augments clinicians, and honors the neurodevelopmental vulnerability of the preterm infant.

Appropriate modulated sensory input e.g., touch, voice, olfactory, and oromotor stimulation can be organizing in a positive way during this period, favouring neurobehavioral organization, autonomic function, and functional connectivity(\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e, \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eAll these interventions are Synactive Theory of Development based, which highlights scaffolding the developing behavioral systems of the infant through individualized and sequenced input(\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e, \u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e). Meanwhile, Family Integrated Care (FICare) and other models encourage the involvement of parents in the NICU both as a therapeutic support and a support system for their emotions(\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e, \u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eYet, formal practice of early sensory stimulation in Indian NICUs is still limited. Practices of stimulation are frequently determined by therapist judgment, infrequently prescribed according to established gestational age, and variably introduced to caregivers. In a recent national audit in india, there was considerable variation in NICUs regarding stimulation routines and parent involvement, as well as delivery by staff(\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e, \u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eAlthough mothers are becoming more visible in NICU environments, especially in state-funded family-centered care units, their role in early habilitative procedures is typically unorganized, intuitive, and guided by no professional expertise. The result is a disjointed care environment in which stimulation is either underutilized, over-used, or presented without consideration for the infant's neurodevelopmental status.(\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eAt a global level, practices like SENSE (Supporting and Enhancing NICU Sensory Experiences) have come up as systematic, gestational age\u0026ndash;specific models of sensory support for preterm infants(\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e). These high-resource-based programs provide week-wise elaborate stimulation plans and define roles for caregivers and professionals. Yet, their applicability in India is constrained by several contextual barriers such as heavy patient loads, variable access to trained therapists, restricted staff-parent ratios, and a lack of standardized parent education streams. Further, cultural practices, hospital facilities, and caregiver expectations are highly variable across Indian NICUs, such that direct importation of such frameworks is difficult.(\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e, \u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e, \u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e, \u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eLow and Middle Income Countries (LMIC) like India needs as a priority is a developmentally sequenced, role-sensitive, and culturally flexible protocol for early stimulation. As opposed to rehabilitation programs geared for post-discharge intervention, early habilitation in the NICU focuses on prevention and facilitation of optimal neurodevelopment by sensory and environmental enrichment prior to term age(\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e, \u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e). Such a protocol would detail with precision which sensory modalities to employ, at what gestational age, in what clinical conditions, and by whom, parent or therapist, or both. It would have to consider not only the empirical evidence that happens to be available but also the demands of clinical practice and the readiness of caregivers to engage in effective therapeutic interaction.\u003c/p\u003e\u003cp\u003eThis research sought to create a gestational age\u0026ndash;specific early stimulation protocol for preterm infants in neonatal intensive care units (NICUs) through the combination of three divergent knowledge sources: structured evidence from published literature, clinical experience from physiotherapists in NICUs, and everyday caregiving experiences from mothers of preterm infants. The goal was to create a week-by-week, developmentally targeted protocol that not only delineates what interventions are suitable for which gestational age group, but also when, how, and by whom they ought to be given. The research aimed to frame these interventions within the realities of care provision in low- and middle-income country (LMIC) NICU environments, specifically in India.\u003c/p\u003e"},{"header":"Methods","content":"\u003cp\u003e\u003cb\u003eStudy Design and Rationale\u003c/b\u003e\u003c/p\u003e\u003cp\u003e This study employed a mixed methods design, integrating both qualitative and structured review components through a formal triangulation process and joint display analysis. Specifically, the study followed a sequential exploratory mixed methods framework. The process started with a systematic review of neonatal stimulation interventions to explore gestational timing, delivery agents, and procedural parameters of evidence-based practice. This was supplemented by two qualitative strands: (i) physiotherapist NICU interviews to record clinical feasibility and implementation logic, and (ii) phenomenological mother interviews to investigate emotional readiness, caregiving behaviors, and perceived barriers to participation.\u003c/p\u003e\u003cp\u003eThe mixed-methods approach was justified methodologically by the multicollinearity of the research question that called for the intersection of empirical data, experiential insight, and caregiver input to yield construct validity and implementation acceptability. Instead of privileging one type of data over another, the design favoured equal weighting among all three sources to inform final protocol decisions. The process culminated in an integration phase using joint display matrices, which allowed direct comparison of findings from the systematic review, therapist interviews, and maternal interviews for each stimulation modality. These matrices facilitated the classification of each intervention-week pairing as convergent, conditional, or divergent and informed the final structure and delivery recommendations of the protocol.\u003c/p\u003e\u003cp\u003e The research was performed according to the GRAMMS (Good Reporting of a Mixed Methods Study) guidelines. Every part followed method-specific criteria, such as PRISMA for the systematic review and COREQ for the qualitative parts. The triangulated synthesis was the core analytic product of this design, generating the meta-inferences required to transition into protocol development.\u003c/p\u003e\u003cp\u003e\u003cb\u003eSequence of study methods\u003c/b\u003e:\u003c/p\u003e\u003cp\u003e\u003cb\u003eComponent 1 - Systematic Review: Mapping of Intervention Characteristics\u003c/b\u003e\u003c/p\u003e\u003cp\u003eThe initial phase was a systematic review, set to not assess the clinical effectiveness of stimulation interventions but to record their structural and developmental parameters. The primary aim was to determine when, how, and by whom various interventions were administered in ongoing randomized trials. Search databases were PubMed, Scopus and Proquest, and articles between 2010 and 2023 were included. The inclusion criteria were RCTs and quasi-experimental studies in NICUs that reported stimulation interventions for preterm infants between 26 to 40 weeks' gestation. Studies without gestational timing or implementation details were excluded.\u003c/p\u003e\u003cp\u003eData extracted included intervention modality (e.g., tactile, auditory, oromotor), gestational week of initiation and cessation, session duration and frequency, and delivery agent (parent, nurse, therapist). A structured data extraction sheet was used in Microsoft Excel by three independent reviewers (AJR, MS, KS) and the conflicts was resolved by another researcher (VK). The extracted data were synthesized into a gestational age-by-modality matrix, which served as the foundation for subsequent triangulation. This mapping allowed visualization of which interventions were structurally feasible across developmental stages, independent of reported outcomes.\u003c/p\u003e\u003cp\u003e\u003cb\u003eComponent 2 \u0026ndash; Therapist Interviews: Clinical Feasibility and Implementation Patterns\u003c/b\u003e\u003c/p\u003e\u003cp\u003eIn the second phase, semi-structured interviews were conducted with physiotherapists working in NICUs across India to understand how stimulation interventions are currently delivered, modified, or withheld in routine practice. A phenomenological lens was adopted to capture therapists\u0026rsquo; lived clinical reasoning and the implicit criteria guiding their practice. Purposive and snowball sampling yielded 16 participants from a range of institutional contexts, including public and private tertiary hospitals across Tamil Nadu, Delhi, Hyderabad, and Bengaluru. Eligibility demanded two years of experience specific to NICU.\u003c/p\u003e\u003cp\u003eTelephone interviews were held in English and ranged from 45 to 60 minutes. A semi-structured interview guide, constructed following literature review and consultation with experts, addressed intervention sequencing, therapist-only interventions, parent training techniques, and decision-making thresholds on the basis of infant readiness. Telephone interviews were recorded with participants' consent, transcribed verbatim, and analyzed with Braun and Clarke's six-phase reflexive thematic analysis. Coding was conducted manually in Excel by two independent researchers, with themes refined iteratively. Final themes included \"routine practices by gestational week,\" \"barriers to parent involvement,\" \"infant stress cue observation,\" and \"therapist discretion versus protocol-driven care.\" Field notes and member checks enhanced credibility. Thematic saturation was used as the stopping criterion. Findings were organized into a therapist feasibility matrix aligned by modality and GA. (\u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e)\u003c/p\u003e\u003cp\u003e\u003cb\u003eComponent 3 \u0026ndash; Maternal Interviews: Readiness and Acceptability\u003c/b\u003e\u003c/p\u003e\u003cp\u003eThe third phase involved a descriptive phenomenological study aimed at capturing mothers\u0026rsquo; lived experiences, emotional responses, and perceived capability to engage in NICU-based stimulation. Twelve mothers of preterm infants (GA 28\u0026ndash;37 weeks), recruited from NICU follow-up clinics, participated in face-to-face interviews conducted in Tamil within the hospital\u0026rsquo;s mother-infant areas. Interviews coincided with skin-to-skin care hours to enhance contextual recall. Eligibility demanded recent NICU experience, continued caregiving duty, and informed consent.\u003c/p\u003e\u003cp\u003eA semi-structured interview guide probed maternal attitudes towards bonding, caregiving behaviors (e.g., holding, talking, feeding), knowledge of stimulation practice, perceived risks, and barriers to participation. Interviews were audio-recorded, transcribed verbatim, and translated into English. A phenomenological reduction technique was applied to identify invariant meaning units that reflected readiness, willingness, fear, instinctive caregiving, and information gaps. Two researchers independently analyzed the transcripts; interpretive alignment was achieved through consensus discussions. The resulting themes were synthesized into a maternal readiness matrix by modality and gestational age, highlighting which interventions mothers practiced intuitively, which required structured introduction, and which were viewed as exclusive to therapists.\u003c/p\u003e\u003cp\u003e\u003cb\u003eTriangulation and Joint Display Analysis\u003c/b\u003e\u003c/p\u003e\u003cp\u003eFollowing the independent analysis of each data stream, the fourth phase involved triangulation using joint display analysis. The goal of this phase was to integrate evidence from the systematic review, therapist practice, and maternal readiness into a unified framework that could inform a gestationally appropriate stimulation protocol.\u003c/p\u003e\u003cp\u003eThe triangulation proceeded in five stages. First, a raw triangulation matrix was constructed for each modality, displaying unaltered data excerpts from all three sources. This ensured analytic transparency and preserved the integrity of each data stream. Second, an interpretive coding step was applied, where each modality-week pair was classified as either convergent (✔), conditional (⚠), or excluded (✖), based on alignment across sources. Conditional codes reflected either the need for therapist supervision, maternal training, or medical stability. Third, a comprehensive joint display matrix was developed, listing each intervention modality, its evidence-based timing and delivery structure, therapist feasibility, maternal acceptability, triangulated judgment, and final protocol decision.\u003c/p\u003e\u003cp\u003eFourth, a gestational week x modality matrix was created, color-coded to indicate convergence and conditionality across weeks 26 to 40. This table translated the protocol into operation and graphically showed the evolution of some interventions (e.g., tactile to tactile-kinesthetic; therapist-to-parent) across time. Lastly, a barrier\u0026ndash;facilitator matrix was built on cross-cutting qualitative themes, siting how emotional, physical, or informational barriers affected feasibility, and illuminating enabling practices like peer support and bedside training.\u003c/p\u003e\u003cp\u003e\u003cb\u003eData Integration Team and Bias Mitigation\u003c/b\u003e\u003c/p\u003e\u003cp\u003eTriangulation and integration were conducted by a three-member analytic team (AJR, MS, KS). Two researchers (AJR, MS) who had led the original coding of therapist and maternal interviews conducted the initial convergence coding. A third researcher (KS), not involved in primary data collection, reviewed all raw and interpreted matrices to challenge potential confirmation bias.

The review-supported inclusion of nesting, skin-to-skin care (KMC), auditory stimulation (maternal voice), and olfactory stimulation from as early as 26\u0026ndash;28 weeks GA. Other modalities such as tactile-kinesthetic input, vestibular stimulation, oromotor support, and visual stimulation were found to be more appropriate from 31\u0026ndash;34 weeks onward. Reflex locomotion and respiratory PNF were mapped to 28\u0026ndash;37 weeks and 30\u0026ndash;40 weeks respectively, but were consistently therapist-led.

Nesting, KMC, auditory stimulation, positioning, and environmental modulation were reported as standard care. Tactile stimulation (Yakson touch), respiratory PNF, and proprioceptive techniques were selectively applied after medical stabilization, particularly in infants above 28\u0026ndash;30 weeks GA.

Using joint display analysis, the study constructed a developmentally sequenced framework of stimulation interventions mapped across 26 to 40 weeks postmenstrual age (PMA).

Therapists indicated these as standard practices, frequently utilized to commence developmental care in ventilated or medically fragile infants\u003c/p\u003e\u003cp\u003eMaternal interviews confirmed high instinctive participation and emotional attachment to these modalities particularly KMC, which many mothers described as pivotal in \"feeling like a mother again.\"(\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e, \u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e)\u003c/p\u003e\u003cp\u003eFrom a theoretical standpoint, this convergence aligns with Als\u0026rsquo; Synactive Theory of Development, which emphasizes the importance of supporting autonomic and self-regulatory subsystems before introducing active engagement(\u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e). These foundational interventions provide proprioceptive containment (nesting), tactile and thermal input (KMC), auditory familiarity (voice), and olfactory comfort (maternal scent), all crucial for promoting neurobehavioral organization in early gestational windows. The inclusion of these from 26 weeks onward, as seen in the Week \u0026times; Modality Matrix, validates their role as non-negotiable pillars of early habilitation.\u003c/p\u003e\u003cp\u003eSeveral modalities Yakson touch, tactile-kinesthetic stimulation, oromotor stimulation, reflex locomotion, respiratory PNF, gustatory stimulation, visual engagement, vestibular input, and multisensory layering were included conditionally, based on gestational readiness, safety thresholds, or caregiver training needs.\u003c/p\u003e\u003cp\u003eYakson touch, supported in literature for calming effects between 26\u0026ndash;30 weeks, was practiced cautiously by therapists but largely unknown to mothers.

While therapists reported performing passive movement routines post-stabilization, mothers, though unaware of the technique, often touched or moved their baby\u0026rsquo;s limbs instinctively. The conditional convergence of this modality suggests it is well-suited for graduated parent involvement, under therapist supervision.\u003c/p\u003e\u003cp\u003eOromotor stimulation was inconsistently practiced by therapists due to clinical constraints, but highly resonant for mothers. Many linked their baby\u0026rsquo;s first sucking reflex or smile to a turning point in their NICU journey.

Mothers were already doing so informally speaking to their baby during feeding, swaying during KMC, or reacting to visual stimuli, emphasizing how natural caregiving activities can become bases for organized stimulation.

Although neither the literature nor therapists explicitly structured these combinations, the presence of such layering in maternal narratives suggests an opportunity to formalize instinctive caregiving into a scaffolded multisensory progression from 31 weeks onward.

The Week \u0026times; Modality Matrix clearly illustrates how some interventions (e.g., Yakson touch) phase out by 30 weeks, while others (e.g., tactile-kinesthetic) phase in at that same window.

The SENSE program, established in high-income environments, is a gold-standard, evidence-based practice that offers week-by-week, sensory stimulation activities to preterm infants.

First, by integrating evidence, clinical reasoning, and caregiver experience into a unified, week-specific protocol, it demonstrates how developmental care can be both structured and participatory. The protocol does not prescribe isolated interventions but instead organizes them as an adaptive, layered habilitation pathway shifting responsibility from therapist to parent as the infant matures, and enabling scalable delegation in overstretched healthcare systems.\u003c/p\u003e\u003cp\u003eSecond, the protocol explicitly addresses therapist-parent dynamics in NICU care. It provides a roadmap for training, supervision, and confidence-building strategies that reflect the gradual transition of stimulation roles. This supports models such as Family Integrated Care (FICare), but advances them by assigning responsibility not only by individual preference but also by developmental readiness, modality complexity, and safety threshold.\u003c/p\u003e\u003cp\u003eThird, by embedding maternal readiness into protocol development, the study moves beyond tokenistic \u0026ldquo;parent involvement\u0026rdquo; and creates conditions for genuine parental empowerment. It legitimates instinctual behaviors such as voice, rocking, face regard and directs them into organized, evidence-based practice. By doing so, it fortifies the therapeutic relationship between parent and clinician, which has been demonstrated to have favorable effects on both neurodevelopment and parental mental health.\u003c/p\u003e\u003cp\u003eFinally, the methodological approach specifically the triangulation and display of the joint Week \u0026times; Modality Matrix provides a model for replication by researchers and policymakers interested in adapting global evidence to developmentally appropriate, culturally viable neonatal interventions.\u003c/p\u003e\u003cp\u003e\u003cb\u003eLimitations\u003c/b\u003e\u003c/p\u003e\u003cp\u003eSeveral limitations warrant consideration. While the systematic review mapped gestational timing and delivery structure of stimulation modalities, it did not assess intervention efficacy or rank outcomes, which limits the ability to prioritize interventions based solely on impact metrics. Second, the review included only English-language trials, potentially excluding relevant regional or non-indexed evidence.\u003c/p\u003e\u003cp\u003e In the qualitative components, the sample of therapists though geographically diverse was limited to physiotherapists, excluding views of occupational therapists, speech therapists, nurses, or neonatologists who may influence care delivery patterns.

Although early stimulation supports neurobehavior, structured, gestational age\u0026ndash;specific protocols are limited in India, where clinical variation and inconsistent caregiver integration persist. The objective of the study is to develop a context-appropriate, week-wise stimulation protocol for preterm infants (26\u0026ndash;40 weeks postmenstrual age) by triangulating research evidence, therapist-informed practices, and maternal readiness.\u003c/p\u003e\u003ch2\u003eMethods:\u003c/h2\u003e\u003cp\u003eA sequential mixed methods approach was adopted. Systematic review of randomized control trials (2010\u0026ndash;2023) charted stimulation timing, dosage and mode. Semi-structured interviews with NICU physiotherapists (n\u0026thinsp;=\u0026thinsp;17) investigated decision-making and feasibility. Phenomenological interviews with mothers (n\u0026thinsp;=\u0026thinsp;12) examined readiness and perceived capacity. Joint display analysis was used to integrate findings and construct a layered stimulation protocol.\u003c/p\u003e\u003ch2\u003eResults:\u003c/h2\u003e\u003cp\u003eCore modalities such as kangaroo care, auditory stimulation (maternal voice), olfactory input, and oromotor stimulation were supported across data sources and included by gestational progression. Notably, nesting/positioning and Yakson touch, absent in trial evidence emerged as critical therapist-led practices, with high maternal acceptability. Modalities such as visual, vestibular, and multisensory input were phased in from 31\u0026ndash;34 weeks based on infant readiness and caregiver confidence.\u003c/p\u003e\u003ch2\u003eConclusion:\u003c/h2\u003e\u003cp\u003eThe resulting protocol provides Low-Middle Income country (LMIC) feasible week-specific, role-sensitive, developmentally layered stimulation model. By aligning evidence, practice, and experience, it offers a feasible, family-integrated habilitation approach for resource-constrained NICUs.\u003c/p\u003e","manuscriptTitle":"Triangulating Evidence, Expertise, and Maternal Experience to Design a Gestational Age- Specific Early Stimulation Protocol for Preterm Infants in Neonatal Intensive Care Unit: A Contextual Multi-Source Framework from India with LMIC Relevance ","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-09-24 11:42:45","doi":"10.21203/rs.3.rs-7305154/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-12-15T05:36:37+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-12-14T18:15:18+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"170535574653622567254587481162105784163","date":"2025-12-14T17:33:42+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-12-06T11:19:07+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"93614482985160636091174650758756021639","date":"2025-12-03T05:12:32+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"75690325398579605040609948752090041637","date":"2025-12-01T05:46:16+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-09-15T14:16:06+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-08-07T18:42:29+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-08-07T18:41:02+00:00","index":"","fulltext":""},{"type":"submitted","content":"Journal of Health, Population and Nutrition","date":"2025-08-06T03:15:24+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"journal-of-health-population-and-nutrition","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"johp","sideBox":"Learn more about [Journal of Health, Population and Nutrition](http://jhpn.biomedcentral.com/)","snPcode":"41043","submissionUrl":"https://submission.nature.com/new-submission/41043/3","title":"Journal of Health, Population and Nutrition","twitterHandle":"@BioMedCentral","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"BMC/SO AJ","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"8792ebca-9578-4efc-be9f-194366185c26","owner":[],"postedDate":"September 24th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2026-04-27T02:24:09+00:00","versionOfRecord":[],"versionCreatedAt":"2025-09-24 11:42:45","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7305154","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7305154","identity":"rs-7305154","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
