Diabetic Peripheral Neuropathy (DPN) is a common complication, characterized by symptoms such as pain, tingling, and numbness due to peripheral nerve damage. The global burden of diabetes has been rising, particularly in low- and middle-income countries. In India, the number of diabetes cases is projected to reach over 134 million by 2045. Traditional treatments for DPN often have limited efficacy and adverse long-term effects, highlighting the need for alternative therapies. Objective : This study aims to investigate the efficacy of electroacupuncture in improving sensory nerve functions in patients with DPN. Specific acupuncture points will be targeted to assess their impact on vibration perception, hot and cold perception, touch sensitivity, and skin temperature. Methods: A randomized controlled trial will be conducted with 80 participants divided equally into an interventional group and a control group. The interventional group will receive electroacupuncture at specific points (ST44, ST36, ST43, K2, K3, BL60, SP9, and GB41) three times a week for 8 weeks. The control group will continue their usual routine and receive the treatment post-study. Primary outcomes will be measured using the NEURO TOUCH instrument to assess sensory thresholds and skin temperature. Secondary outcomes will include pain assessment using the Visual Analog Scale (VAS). Data will be analyzed using SPSS version 16. Results : The study will evaluate the degree of sensory improvement in peripheral nerves and the effectiveness of electroacupuncture in reducing neuropathic pain. This research seeks to bridge the gap in understanding the mechanisms and efficacy of electroacupuncture in DPN treatment. Conclusion : This study will provide significant insights into the potential benefits of electroacupuncture for DPN, offering an alternative approach to improve the management of this debilitating condition. The findings could inform future clinical practices and guidelines for DPN treatment. Diabetes Diabetic Peripheral Neuropathy Electroacupuncture Sensory Nerve Function Vibration Perception Pain Management Figures Figure 1 Figure 2 INTRODUCTION Diabetes is a chronic metabolic disease that affects millions of people globally. Type 2 diabetes is the most common form, and type 1 diabetes is persistent and requires insulin. Symptoms include frequent urination, thirst, hunger, weight loss, vision changes, and fatigue. Healthy habits such as regular exercise and healthy eating can prevent type 2 diabetes and its complications. The bulk of the approximately 422 million individuals with diabetes globally reside in low- and middle-income nations, and diabetes is directly responsible for 1.5 million fatalities annually. Over the past several decades, there has been a consistent rise in both the incidence and prevalence of diabetes. (1) Over the past three decades, the worldwide burden of diabetes has gradually increased, with India bearing a substantial share of this burden. In India, 77 million people were estimated to have diabetes in 2019, and by 2045, that number is projected to reach over 134 million. (2) Diabetes can damage the peripheral nervous system, causing distal symmetric polyneuropathy (DSP) with symmetrical sensory problems like pain, tingling, and numbness. The prevalence of Diabetic Peripheral Neuropathy is 33.33% in southern India, with risk factors including hypertensive diabetes and diabetes with dyslipidemia. (3) The treatment of diabetic peripheral neuropathy is frequently insufficient, and it is yet unknown how to precisely improve glycemic control in type-2 diabetes. Exploring the mechanisms of action and efficacy of various treatments is essential. For the management of DPN, important worldwide clinical guidelines suggest a number of symptomatic therapies. Tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors, and anticonvulsants that block calcium channels are among the first-line treatments. Opioids and topical medications like lidocaine and capsaicin are examples of other treatments. (4) Pharmacological management of Diabetic Peripheral neuropathy is bearing more deteriorate effects after long-term use of pharmacological remedies. So, the implementation of non-pharmacological interventions like acupuncture and its different modalities is much needed for the hour. Acupuncture is the most popular traditional Chinese medicine accepted worldwide for the treatment of various illnesses. According to traditional Chinese medicine, Diabetic Peripheral Neuropathy is considered a type of “Bi Syndrome”. It occurs when pathogenic factors block the meridian, leading to blood stasis and meridian starvation. (5) Acupuncture and moxibustion can treat diabetic peripheral neuropathy by clearing the meridians and stimulating qi flow. Acupuncture has been researched more, moxibustion may be a safer and less invasive option for diabetic peripheral neuropathy patients with poor wound healing. (5) There are some recent studies showing the effect of acupuncture, acupuncture, and tuina on the treatment of diabetic neuropathy. Acupuncture and Tuina are useful in treating DPN, according to clinical reports. (6) Although electroacupuncture have been studied as a potential treatment for diabetic peripheral neuropathy, there is still a lack of research on the effects of particular point combinations on neuropathic abnormalities or the degree of improvement in sensory function in the lower extremities. This research will center on specific points [(ST44 (Neiting), ST36 (Zusanli), ST43 (Xiangu), K2 (Rangu), K3 (Taixi), BL60 (Kunlun), SP9 (Yinlingquan), and GB 41 (Zulinqi)] to examine various sensory components (Vibration Perception Threshold, Cold & Hot Perception Threshold, Touch Perception and Skin temperature). This study aims to bridge this critical gap in knowledge by conducting a comprehensive investigation of the effect of electroacupuncture on Sensory Peripheral Nerve Functions in Diabetic Peripheral Neuropathy. The study will contribute significant insight into the potential benefits of this novel intervention, thereby offering a better option for improved management and alleviation of diabetic peripheral neuropathy-associated symptoms. AIM AND OBJECTIVES Aim: To assess the degree of sensory improvement in peripheral nerves of Diabetic Peripheral Neuropathy patients. Objectives: Primary Objective: To study the impact of electroacupuncture at particular acupuncture points on the vibration threshold, hot and cold perception, touch sensitivity, and skin temperature in patients with diabetic patients.

MATERIALS AND METHODS Study design: The study will employ a randomized control study design, as it is a widely recognized method for testing the effectiveness of interventions. This design involves randomly assigning participants to either a treatment group or a control group, to compare the outcomes of the two groups. By utilizing this rigorous approach, we can ensure that the results of the study are accurate and reliable, and can be used to inform future research and practice in the field. Study Population General Description : The study population will consist of individuals aged 40 to 60 years visiting the outpatient department of the International Institute of Yoga and Naturopathy Medical Sciences in Chengalpattu, India. Participants will be diagnosed with Diabetic Peripheral Neuropathy (DPN) and have had diabetes for more than 5 years, with an HbA1C level greater than 7%. They will exhibit symptoms and/or signs of peripheral nerve damage, such as altered sensitivity to pain, vibration, or pressure, after ruling out other potential causes. The inclusion criteria ensure that participants are willing to provide written informed consent, capable of understanding research procedures, and willing to adhere to them for the study's duration. Exclusion criteria include DPN caused by factors other than diabetes, cardiovascular disorders, psychoneurotic conditions, known hypersensitivity to acupuncture, and open wounds or burns in specific acupuncture points of intervention. The study population aims to represent individuals with DPN seeking treatment in a clinical setting, providing a diverse sample for the evaluation of electroacupuncture as a therapeutic intervention. Sample Size Determination and Power Analyses : The sample size for this study was determined based on achieving 90% power to detect a statistically significant difference in sensory improvement between the interventional and control groups. Given the complexity of the analysis and the need to ensure adequate power, a sample size of 40 participants per group was calculated. The power analysis was conducted using standard statistical methods, taking into account the expected effect size based on previous literature, the chosen significance level (typically α = 0.05), and the desired power level (typically 80% or higher). For this study, a power analysis was performed using software such as G*Power or PASS, considering the primary outcome measures of vibration perception threshold, hot and cold perception, touch sensitivity, and skin temperature. The effect size was estimated based on previous studies examining similar interventions, allowing for a conservative estimation to ensure adequate power. The resulting sample size of 40 participants per group provides sufficient statistical power to detect meaningful differences in sensory improvement between the intervention and control groups, while also considering potential dropouts and variability within the study population. Overall, the sample size determination and power analysis were conducted rigorously to ensure that the study would yield reliable and statistically significant results, contributing valuable insights into the efficacy of electroacupuncture for diabetic peripheral neuropathy.

This research will center on specific points [(ST44 (Neiting), ST36 (Zusanli), ST43 (Xiangu), K2 (Rangu), K3 (Taixi), BL60 (Kunlun), SP9 (Yinlingquan), and GB 41 (Zulinqi)] to examine various sensory components (Vibration Perception Threshold, Cold \u0026amp; Hot Perception Threshold, Touch Perception and Skin temperature). This study aims to bridge this critical gap in knowledge by conducting a comprehensive investigation of the effect of electroacupuncture on Sensory Peripheral Nerve Functions in Diabetic Peripheral Neuropathy. The study will contribute significant insight into the potential benefits of this novel intervention, thereby offering a better option for improved management and alleviation of diabetic peripheral neuropathy-associated symptoms.\u0026nbsp;\u003c/p\u003e"},{"header":"AIM AND OBJECTIVES","content":"\u003cp\u003e\u003cstrong\u003e\u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; \u0026nbsp; Aim:\u0026nbsp;\u003c/strong\u003e\u003c/p\u003e\n\u003cul\u003e\n \u003cli\u003eTo assess the degree of sensory improvement in peripheral nerves of Diabetic Peripheral Neuropathy patients. \u0026nbsp;\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e\u003cstrong\u003eObjectives:\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003ePrimary Objective:\u0026nbsp;\u003c/em\u003e\u003c/strong\u003e\u003c/p\u003e\n\u003cul\u003e\n \u003cli\u003eTo study the impact of electroacupuncture at particular acupuncture points on the vibration threshold, hot and cold perception, touch sensitivity, and skin temperature in patients with diabetic patients.\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eSecondary Objectives:\u003c/em\u003e\u003c/strong\u003e\u003c/p\u003e\n\u003cul\u003e\n \u003cli\u003eTo evaluate how patients with diabetic peripheral neuropathy respond to electroacupuncture at particular acupuncture points for neuropathic pain. \u0026nbsp;\u0026nbsp;\u003c/li\u003e\n\u003c/ul\u003e\n\u003cp\u003e\u003cstrong\u003eParticipating Units\u003c/strong\u003e:\u003c/p\u003e\n\u003cp\u003e1.

Diabetic Peripheral Neuropathy (DPN) is a common complication, characterized by symptoms such as pain, tingling, and numbness due to peripheral nerve damage. The global burden of diabetes has been rising, particularly in low- and middle-income countries. In India, the number of diabetes cases is projected to reach over 134 million by 2045. Traditional treatments for DPN often have limited efficacy and adverse long-term effects, highlighting the need for alternative therapies.\u003cstrong\u003e\u0026nbsp;\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eObjective\u003c/strong\u003e: This study aims to investigate the efficacy of electroacupuncture in improving sensory nerve functions in patients with DPN. Specific acupuncture points will be targeted to assess their impact on vibration perception, hot and cold perception, touch sensitivity, and skin temperature.\u003cstrong\u003e\u0026nbsp;\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMethods:\u003c/strong\u003e A randomized controlled trial will be conducted with 80 participants divided equally into an interventional group and a control group. The interventional group will receive electroacupuncture at specific points (ST44, ST36, ST43, K2, K3, BL60, SP9, and GB41) three times a week for 8 weeks. The control group will continue their usual routine and receive the treatment post-study. Primary outcomes will be measured using the NEURO TOUCH instrument to assess sensory thresholds and skin temperature. Secondary outcomes will include pain assessment using the Visual Analog Scale (VAS).
