Reframing Frailty, Falls, and Sarcopenia: A Marxist-Informed Analysis of Deficit-Oriented Geriatrics and a Resource Roadmap for Healthy Ageing in Health Professionals [version 1; peer review: awaiting peer review] . F1000Research 2026, 15 :512 ( https://doi.org/10.12688/f1000research.178827.1 ) First published: 15 Apr 2026, 15 :512 ( https://doi.org/10.12688/f1000research.178827.1 ) Latest published: 15 Apr 2026, 15 :512 ( https://doi.org/10.12688/f1000research.178827.1 ) Introduction Frailty, sarcopenia, and falls are clinically described phenomena that shape the lives of older adults and frequently inform decision making across the health professions (HP) and in geriatric care ( Fried et al., 2001 ; Sherrington et al., 2019 ). Within established practice, these conditions are commonly conceptualised as individual deficits that can be modified through targeted exercises, education, and behavioural compliance ( Cruz-Jentoft et al., 2019 ; Sherrington et al., 2019 ). While this perspective provides standardised assessments and measurable therapeutic endpoints, it only partially captures the conditions under which vulnerability in later life emerges. The social and material environments in which risks accumulate, are produced, or become visible remain insufficiently addressed within behaviour focused corrective frameworks ( Beard et al., 2016 ; Greenhalgh & Papoutsi, 2018 ; Marmot, 2020 ) . By contrast, international frameworks on Healthy Ageing and Intrinsic Capacity conceptualise older adults primarily in terms of functional ability and the enabling conditions located in concrete life environments. They emphasise the role of mobility spaces, living arrangements, social networks, and digital accessibility as central determinants of functional trajectories and of the effectiveness of any health related intervention ( Beard et al., 2016 ; Chhetri et al., 2022 ). This broader perspective complements biomedical evidence by embedding it within the social, material, and relational contexts that shape opportunities for participation and everyday autonomy ( Beard et al., 2016 ; Chhetri et al., 2022 ). Aim and theoretical positioning The aim of this paper is to analyse frailty, sarcopenia, and fall prevention through a Marxist informed perspective that conceptualises health as the outcome of social and material living conditions and understands the deficit orientation of HP practice as an effect of professional socialisation shaped by economic and institutional structures ( Marmot, 2020 ; Moncrieff, 2008 ). The paper situates itself explicitly within the political economy of health and engages with central concepts of this tradition, including class relations shaping exposure to risk, the societal production of health and illness, structural vulnerability, and the critique of individualised responsibility. In this perspective, frailty and fall risks are interpreted as manifestations of material living conditions rather than attributes of individual bodies, complementing rather than contradicting biomedical understandings. By connecting this theoretical lens with current geriatric and biomedical evidence, the paper argues for a resource oriented conceptualisation of Healthy Ageing that foregrounds enabling environments, functional ability, and participation. Epidemiological research consistently demonstrates a social gradient in frailty, multimorbidity, and fall related morbidity, with lower socioeconomic status linked to earlier onset and more severe trajectories ( Beard et al., 2016 ; Marmot, 2020 ). Behaviour oriented interventions may be effective at the individual level, but their structural impact remains limited as long as the conditions that produce and reproduce vulnerability remain unchanged (Moncrieff, 2022; Beard et al., 2016 ). This paper therefore offers a conceptual analysis that brings together political economic perspectives, geriatric evidence, and social theory to examine implications for HP practice, education, and health policy. Problem statement The biomedical framing of geriatrics conceptualises frailty as an interaction of muscle weakness, reduced physiological reserve, slowness, and energy deficits, sarcopenia as declining muscle mass and strength in relation to nutrition and activity, and falls as events resulting from an individual constellation of risk factors. Within this framing, intervention oriented pathways emerge that prioritise strength training, balance training, risk communication, and education. The evidence supporting these approaches is substantial, as demonstrated by reviews of fall prevention programmes and research on the benefits of resistance training in community dwelling older adults ( Gillespie et al., 2009 ; Sherrington et al., 2019 ). However, their effects often remain fragile when housing environments, neighbourhood structures, and social infrastructures continue to produce fall risk and when access to nutrition, mobility, and social participation is unequally distributed. From a sociological perspective, screening and risk stratification become meaningful only when linked to pathways for modifying contextual and environmental conditions rather than confined to labelling individuals. Otherwise, a semantic and practical shift occurs that individualises causes, moralises responsibility, and leaves structural levers unused ( Gillespie et al., 2009 ; Santos-Eggimann & Sirven, 2016 ; Sherrington et al., 2019 ). For analytical clarity, this paper distinguishes between structural determinants of frailty such as income, housing quality, cumulative life course disadvantage, and access to care, and the biomedical parameters that manifest clinically as muscle weakness, functional decline, or reduced physiological reserve. The former shape the distribution, onset, and severity of the latter. Marxist-informed framework A Marxist informed analysis understands health and illness as outcomes of social, economic, and material conditions rather than properties of individual bodies. This perspective directs attention to work, income, housing, infrastructure, education, and the organisation of insurance and healthcare systems as central determinants shaping health trajectories across the life course. These conditions accumulate over decades, influencing which resources people are able to acquire or lose, and structuring exposure to both risks and protections. From this standpoint, frailty, sarcopenia, and fall risks are socially patterned and therefore predictable, as class relations play a key role in determining differential access to supportive environments and recovery opportunities. This interpretation does not oppose biological evidence but expands it by explaining how biological vulnerabilities arise, interact, and intensify within specific material and social environments. The prognostic value of frailty indices illustrates how clinically observable deficits in functional reserve matter, yet without structural intervention pathways, such prognostic information remains therapeutically limited. Ageing processes and neurodegenerative risks are real, but they unfold within social worlds that can either amplify or mitigate their effects. Recognising this provides the basis for shifting the conceptual focus from repairing individual bodies to shaping the environments in which those bodies live and age ( Kojima, 2017 ; Moncrieff, 2008 ; Nicholls, 2017 ). Deficit orientation as socialisation Deficit orientation in HP can be understood not simply as a clinical method but as a learned interpretive pattern embedded in professional socialisation. This pattern is reproduced through educational curricula, professional development pathways, and organisational routines, and is reinforced by reimbursement structures and regulatory systems. Within these contexts, students and practitioners are socialised to focus on pathologies, impairments, and deviations from normative bodily functioning. Assessment practices and examinations reward diagnostic precision at the bodily level more strongly than contextual awareness or the identification of social and material resources. Specialisation pathways further stabilise this interpretive lens by defining advanced competence as the increasingly fine grained localisation and correction of dysfunction. Organisational and insurance logics create incentives to document measurable deficits to legitimise therapy, while context oriented and participation focused work receives less institutional visibility and financial support. From a Marxist informed perspective, these professional norms and institutional arrangements represent a form of ideological socialisation rather than neutral technical practice. Billable, standardisable interventions are structurally prioritised, whereas work addressing social conditions, environments, and participation tends to be marginalised within reimbursement systems. This structural stability helps explain why appeals to individual attitude change have limited impact and why institutional and financial reorganisation is necessary to enable substantive shifts in practice ( Moncrieff, 2008 ; Nicholls, 2017 ). Frailty, sarcopenia, and fall prevention in context Frailty has strong prognostic value, yet its dominant semantic framing frequently individualises causality and promotes intervention programmes centred on exercise plans, behaviour change, and compliance. While such programmes may be clinically beneficial, they remain insufficient when decades of physically demanding work, precarious income, and limited opportunities for rest and recovery have already depleted functional reserves, or when neighbourhood and housing environments restrict mobility. Under these conditions, screening becomes meaningful only when linked to pathways for modifying environmental and social contexts rather than functioning primarily as a means of individual classification. In sarcopenia research, the benefits of strength training, adequate protein intake, and diagnostic innovations such as ultrasound based muscle assessment are well established. However, sustainable effects depend on broader conditions, including access to safe movement spaces, adequate nutrition, and opportunities for meaningful participation. Comorbidities such as type 2 diabetes intersect with socially unequal recovery opportunities and intensify trajectories of decline, illustrating how biological processes are shaped and mediated by social and material inequalities. Similarly, evidence for multifactorial fall prevention programmes is robust, yet effects remain fragile when pavements are poorly lit, crossing times are short, winter services are unreliable, or housing environments cannot be adapted. In this context, individualising logics can create expectations that older adults must exercise correctly and behave cautiously, while diverting attention away from the structural responsibility to shape supportive environments. A context oriented perspective makes this gap visible by conceptualising environment, housing, and social embeddedness not as adjuncts to individual intervention but as constitutive elements of late life health and function ( Clemson et al., 2008 ; Gillespie et al., 2009 ; Hoogendijk et al., 2019 ; Kojima et al., 2018 ; Sherrington et al., 2019 ). Healthy ageing as an alternative Healthy Ageing and the framework of Intrinsic Capacity offer a conceptual alternative that shifts attention from cataloguing deficits to examining the social, material, and environmental conditions that enable older adults to pursue meaningful activities and roles. Rather than focusing primarily on impairments, this perspective foregrounds functional ability as something produced through the interaction of individual capacities with supportive environments. Mobility infrastructures, housing quality, social networks, and digital accessibility become central determinants of whether functional ability can be maintained or restored. Gerophysiological research demonstrates how training stimuli, environmental demands, and systemic adaptations interact, but within a Healthy Ageing perspective these biological processes are situated within everyday life rather than treated as isolated mechanisms. Measures of impairment thus become mediators rather than endpoints, embedded in a broader set of social and environmental affordances. This shift aligns with public health frameworks emphasising the structural and environmental supports required for functional ability and participation. International evidence similarly indicates that incorporating capability based perspectives and contextual work is essential for translating short term functional improvements into sustainable gains in daily life and overall quality of life ( Beard et al., 2016 ; Chhetri et al., 2022 ; Webber et al., 2010 ). Context-integrated practice In practice, a context integrated approach requires linking assessments and interventions to the social and material environments in which older adults live. Functional tests such as the Chair Rise Test and the Timed Up and Go retain their relevance, but within this approach they are systematically complemented by assessments of mobility infrastructures, housing functionality, social resources, and digital access. Participation oriented goals shape the selection and intensity of interventions, emphasising the relational and environmental conditions that make functional improvements meaningful. Interventions therefore extend beyond clinical spaces and into everyday environments, including neighbourhood routes, resting points, and crossing infrastructures. Housing adaptations become collective and institutional tasks, requiring coordination between providers, municipalities, insurers, and families rather than relying on individual initiative alone. While strength training continues to play an important role, it becomes embedded in everyday routines and social practices rather than being conceptualised as isolated therapeutic activity. Documentation and outcome measurement reflect this reframing by incorporating participation indicators, environmental changes, and implementation processes alongside traditional metrics such as falls, hospitalisations, and functional test results. Through this shift, care practices become more integrated and context sensitive, allowing the effects of established interventions to translate into sustainable everyday functioning. Recent reviews of fall prevention and training interventions support the argument that combining biomedical components with environmental and contextual modification produces more durable outcomes ( Gillespie et al., 2009 ; Sherrington et al., 2019 ). Education and professional practice For context integrated practice to become sustainable, the professional socialisation of physiotherapists must be understood as a central mechanism through which deficit oriented logics are reproduced or challenged. Within current training structures, curricular emphases, assessment formats, and organisational expectations privilege biomedical reasoning and the identification of impairments, which in turn shape how professionals interpret frailty, sarcopenia, and fall risk ( Beard et al., 2016 ; Chhetri et al., 2022 ; Greenhalgh, 2017 ; Marmot, 2020 ; World Health, 2010 ). Integrating political economy, social determinants of health, discourse analysis, and Healthy Ageing frameworks into HP and geriatric education offers a different epistemic orientation, one that foregrounds the social and material contexts that shape late life health ( Chhetri et al., 2022 ; World Health, 2010 ). Through such lenses, students learn how discourses surrounding frailty and sarcopenia naturalise deficit based interpretations and how alternative resource and context oriented framings can be constructed and justified. Assessment practices that attend to contextual reasoning, participation goals, and intersectoral coordination make visible forms of competence that extend beyond the correction of bodily dysfunction. Emerging tools such as Entrustable Professional Activities can articulate these competencies by including the ability to assess life contexts, engage with community level actors, and develop pathways that enhance older adults’ participation ( Skivington et al., 2021 ). Continuing education and professional development also play a crucial role. When advanced practice is defined primarily as increasingly precise localisation of deficits, the profession is steered toward narrow biomedical expertise. Reorienting advanced practice toward the design and implementation of complex, context sensitive interventions shifts professional identity toward a broader social and environmental remit Quality indicators can further stabilise this reorientation by valuing structural interventions, durable participation gains, and reductions in environmental fall hazards, thereby rendering contextual work institutionally visible. Such changes align with theoretical and empirical evidence and position physiotherapeutic effectiveness as the shaping of conditions in which people age, rather than solely the correction of individual deviations ( Greenhalgh & Papoutsi, 2018 ; Nicholls, 2017 ; Skivington et al., 2021 ). Quality indicators can further stabilise this reorientation by valuing structural interventions, durable participation gains, and reductions in environmental fall hazards, thereby rendering contextual work institutionally visible. Such changes align with theoretical and empirical evidence and position physiotherapeutic effectiveness as the shaping of conditions in which people age, rather than solely the correction of individual deviations ( Beard et al., 2016 ; Moncrieff, 2008 ). Research Research that aligns with a context oriented perspective requires methodological approaches capable of capturing how social, material, and institutional environments shape late life health. Rather than generating evidence on isolated interventions, a structurally embedded research agenda examines how combinations of training, housing modifications, neighbourhood conditions, and digital access interact within everyday life. Complex intervention approaches, such as those outlined in the United Kingdom Medical Research Council Framework, are well suited to this task as they evaluate programmes under real world conditions and attend to the interplay between clinical, environmental, and organisational components ( Skivington et al., 2021 ). Mixed methods designs can clarify mechanisms linking environmental change to functional trajectories, such as how reductions in mobility barriers lead to increased out of home activity, subsequent gains in strength, reduced falls, and enhanced participation ( Clemson et al., 2008 ; Hoogendijk et al., 2019 ). Comparative studies between behaviour oriented and context integrated programmes allow for differentiated analyses of effectiveness and cost benefit profiles, highlighting the limits of intervention models that remain narrowly individualised ( Gillespie et al., 2009 ; Sherrington et al., 2019 ). Diagnostic innovations such as ultrasound based muscle assessment likewise require situating within contextual conditions. Their potential value depends not only on measurement precision but on whether individuals have access to supportive environments that enable meaningful use of diagnostic information ( Chen et al., 2024 ). Research that examines pathways between comorbidities such as type 2 diabetes, emergent sarcopenic trajectories, and socially unequal opportunities for recovery is essential for understanding how biological vulnerabilities intersect with political economic conditions. Taken together, existing evidence suggests that an integrative, context sensitive research agenda represents the next developmental step for understanding frailty, sarcopenia, and fall risk. Such an agenda moves beyond evaluating isolated interventions to examining the structural and environmental conditions that shape whether findings translate into sustainable improvements in everyday ( Clemson et al., 2008 ; Gillespie et al., 2009 ; Hoogendijk et al., 2019 ; Letts et al., 2010 ). Policy From a political economy perspective, the viability of a resource oriented approach to HP depends on the policy and financing structures within which practice is embedded. Current reimbursement systems in many settings prioritise standardised, individually delivered interventions, thereby reinforcing deficit oriented models and limiting institutional support for context related work. When coordination activities, environmental assessments, or housing adaptations are not recognised within reimbursement schemes, they remain structurally marginal regardless of their demonstrated contribution to participation and late life functioning ( World Health, 2010 ). Policy frameworks that link funding to meaningful participation outcomes rather than solely to functional scores can shift incentives toward forms of practice that address the social and material conditions shaping older adults’ lives ( Beard et al., 2016 ). At the municipal level, age friendly infrastructure, reliable winter maintenance, and investments in accessible public spaces constitute the environmental preconditions for sustaining the effects of clinical interventions ( Marmot, 2020 ). Income dependent support for housing adaptations illustrates how redistributive measures can mitigate structural barriers that disproportionately affect socioeconomically disadvantaged older adults. Digital inclusion policies also play a critical role. When access to digital tools, literacy, and support is treated as a public service, technologies such as telerehabilitation or digital navigation can extend rather than restrict opportunities for participation ( Chhetri et al., 2022 ). These policy orientations align with the international Healthy Ageing framework and correspond with evidence demonstrating that the effects of multifactorial fall prevention programmes depend on the broader environmental and social contexts in which older adults live ( Beard et al., 2022 ; Gillespie et al., 2009 ). Taken together, such policy arrangements illuminate how environments become treatable and how the effectiveness of HP is shaped by political and regulatory structures. They underscore that sustainable improvements in late life functioning require not only clinical expertise but institutional conditions that enable structurally informed practice. Objections and responses Common objections to context oriented approaches can be interpreted as reflections of broader institutional logics and professional identities. Concerns about limited time, for example, typically emerge within organisational environments structured around high throughput models of care, where remuneration and workflow prioritise individually delivered, standardised interventions. These concerns overlook how structural modifications can influence medium and long term trajectories of falls, hospitalisation, and care needs, and how such work can be distributed across teams and community partners rather than relying solely on individual practitioners ( Sherrington et al., 2019 ). The argument that context oriented work falls outside the core of HP reflects professional boundaries shaped by biomedical epistemologies. Frameworks such as Healthy Ageing and the International Classification of Functioning, Disability and Health position participation as a central outcome, which makes environmental and social factors immediate determinants of functional ability rather than peripheral considerations ( Beard et al., 2016 ). Resistance to this broader remit can therefore be understood as boundary work that protects existing models of expertise. Questions about the evidence base often stem from the assumption that individual level behavioural interventions constitute the normative standard. Yet robust evidence already exists for many constituent components, including strength training, multifactorial fall prevention programmes, and housing adaptations. The challenge lies not in the absence of evidence but in integrating these elements under real world conditions where environmental and social barriers shape the extent to which interventions can take effect ( Gillespie et al., 2009 ). Preferences for simple exercise based approaches similarly reflect institutional and cultural expectations for discrete, easily standardised interventions. Rather than contradicting context oriented models, such preferences highlight the importance of designing practices that are meaningful and feasible within everyday life. When participation goals become achievable, motivation and engagement typically increase, and exercise becomes a means rather than an end. Current reviews support these dynamics and underscore the need to embed intervention components within the social and material contexts that shape ageing ( Gillespie et al., 2009 ; Sherrington et al., 2019 ). Conclusion Frailty, sarcopenia, and fall risks are not merely attributes of ageing bodies but condensations of social life trajectories shaped by material conditions, institutional arrangements, and cumulative disadvantage. Behaviour centred approaches retain clinical value, yet they risk obscuring the broader structural determinants that pattern unequal ageing across populations. A resource oriented Healthy Ageing perspective offers a conceptual alternative by linking biomedical processes to the social and environmental contexts in which they unfold, thereby foregrounding participation, capability, and the enabling conditions of everyday life. Theoretically, this reframing aligns with perspectives from the political economy of health and critical medical sociology, which emphasise how class relations, infrastructures, and institutional logics shape embodied vulnerability. Empirically, it builds on established evidence in frailty, sarcopenia, and fall prevention, while highlighting the need for research designs that situate interventions within real world contexts. Practically, the analysis illustrates how clinical practice, education, research, and policy can be understood as interconnected domains that together structure the conditions under which later life health is produced. By situating HP within these broader social processes, the paper argues that effectiveness lies not only in strengthening bodies but in shaping the environments and conditions that make functional ability possible. Such a shift contributes to more equitable and sustainable forms of care in ageing societies and clarifies the role of health professions within wider structures of social organisation ( Beard et al., 2016 ; Chhetri et al., 2022 ; Moncrieff, 2008 ).
