Effect of vibration therapy on fasting glucose, insulin level and HOMA2 score in women with pre-diabetes history

Abstract

Introduction: Low frequency vibrations affect the whole body. It’s proposed that they can be an effective tool to improve glycemia by the activation of a large number of muscle fibers. The therapy effectiveness depends on the use of a stimulus characterized by appropriate parameters (frequency, amplitude, time) and proper propagation. Aim of the study: The aim of the study was to evaluate the effect of a series of 21 treatments using oscillating-cycloid vibrations on carbohydrate metabolism in women over 55 years with history of fasting hyperglycaemia in their medical history. Material and methods: The study involved 50 women (age: 67.0 ± 5.9) randomly assigned to groups. The study group was subjected to 21 vibration therapy interventions, the control group participated in the procedures using specially modified placebo devices. Before the start of the treatment and on days 10 and 21, glucose and insulin levels were measured and then HOMA2IR, HOMA% B and HOMA% S. were calculated. Results: After 21 days of vibrations, a significant decrease in insulin concentration was noted in the experimental group (from 21.9 ± 11.2 μIU / ml to 12.8 ± 2.7 μIU / ml). This effect was confirmed by the change in the HOMA2IR index. Conclusions: The stimulus applied in the form of 21 vibration treatments seems to be a promising form of therapy in the studied group. These results indicate the need for further testing with addition of nutrition control.
