Abstract
Background: Diabetes Mellitus (DM) is a major global health issue, leading to significant morbidity and mortality. Effective management often involves lifestyle modifications, including physical activity, which many patients find challenging to maintain. Whole Body Vibration (WBV) training has emerged as a potential alternative to traditional exercise, promising similar benefits with less physical strain.
Objective: This study aimed to determine the effects of WBV training on glycemic control, specifically HbA1c and FBS levels, in patients with Type 2 diabetes.
Methods: A double-blinded randomized controlled trial was conducted from April 2019 to May 2020 with 30 Type 2 diabetes patients recruited from a primary care center in Karachi using simple random sampling. Participants were randomly assigned to the intervention group (n=15) receiving WBV training thrice weekly for twelve weeks, or the control group (n=15) continuing usual medications and diet. WBV exercises were performed on a Power Plate® with increasing vibration frequency and amplitude. Primary outcomes, HbA1c and FBS, were assessed at baseline and after twelve weeks. Data analysis used SPSS version 25 with paired and independent t-tests.
Results: The intervention group showed significant reductions in HbA1c (7.97 ± 1.39 to 7.7 ± 1.28, p<0.05) and FBS levels (136.13 ± 21.63 to 123.46 ± 17.34, p<0.05). The control group showed no significant changes in HbA1c (7.62 ± 0.85 to 7.6 ± 0.81, p>0.05) or FBS levels (138.9 ± 15.7 to 136.9 ± 13.2, p>0.05). Between-group analysis confirmed the intervention group's significant improvements.
Conclusion: Twelve weeks of WBV training significantly improved glycemic control in patients with Type 2 diabetes, showing its potential as an alternative to traditional exercise. Future studies should involve larger, diverse populations and longer follow-up periods to confirm these findings and assess long-term benefits.
