ABSTRACT

Background: Diabetic Peripheral Neuropathy is a common complication of Type II Diabetes Mellitus associated with impaired proprioception, balance deficits, and reduced functional mobility, leading to increased risk of falls and decreased quality of life. Whole-Body Vibration Training (WBVT) has emerged as an effective rehabilitation approach for improving neuromuscular activation and postural control. However, the optimal frequency and intensity of WBVT for individuals with DPN remain unclear. Aim: The study aimed to determine the optimal frequency and intensity of WBVT for improving balance and functional mobility in individuals with DPN. Methodology: A randomized controlled trial was conducted among 45 participants with Type II Diabetes Mellitus and Diabetic Peripheral Neuropathy aged between 50–65 years. Participants were randomly allocated into three groups: low-frequency WBVT, moderate-frequency WBVT, and high-frequency WBVT. All groups underwent WBVT three sessions per week for six weeks. Outcome measures included the Berg Balance Scale (BBS), Functional Reach Test (FRT), and Timed Up and Go Test (TUG). Pre-test and post-test assessments were performed and analyzed using paired t-test and one-way ANOVA. Results: All groups demonstrated significant improvement in balance and functional mobility following intervention (p < 0.05). However, the moderate-frequency WBVT group showed greater improvement in BBS, FRT, and TUG scores compared to the low-frequency and high-frequency groups. Conclusion: Moderate-frequency and moderate-intensity WBVT was found to be more effective in improving balance and functional mobility in individuals with Diabetic Peripheral Neuropathy and may be considered a safe and beneficial rehabilitation intervention.
