MON-624 Effect of Whole Body Vibration on Glycemic Control in Adults with Type 2 Diabetes

Abstract

Introduction: Physical activity plays an important role in glycemic control in patients with type 2 diabetes, but overall adherence rate is low. For patients not able or willing to engage in regular physical exercise, whole body vibration comes as a potential alternative. Objective: To evaluate the effect of 28Hz whole body mechanical vibration on glycemic control and other metabolic parameters in patients with type 2 diabetes. Methods: 24 adults with type 2 diabetes on oral antidiabetic agents, with a baseline HbA1c between 6.5 and 9.0%, were randomized into two groups. The control group (CG) was advised to adopt lifestyle modifications, and the intervention group (IG) received the same orientations and used a 28 Hz whole body vibrating platform daily for 20-30 minutes during 12 weeks. Results: Data from 22 patients were analyzed (one from each group was excluded). Baseline characteristics of both groups were similar except for triglycerides, which were higher in the CG (111.8±39.9 mg/dL vs. 188.9±68.8 mg/dL, p<0.05). After 12 weeks, there was a significant reduction in glycated hemoglobin in the IG (7.69±0.49 vs. 7.17±0.77%, p<0.05), not observed in the CG (8.05±0.98 vs. 7.92±1.07%, p=0.52). A non-significant trend for weight loss in IG was observed (78.14±10.47 vs. 77.14±11.08Kg, p=0.069). There were no significant differences between the groups regarding fasting blood glucose or any other clinical and biochemical variables analyzed. Conclusion: This study suggests an improvement in glycated hemoglobin at 12 weeks with the use of the 28Hz vibration platform in patients with type 2 diabetes. However, further studies with a larger number of patients and longer follow-up are needed to better define the role of whole body vibration as an adjuvant in glycemic control.
