Brief Summary

In order to determine the effect of whole body vibration on TcPO2 levels in patients with type 2 diabetes, 40 subjects will undertake whole body vibration exercise three times a week for 12 weeks. TcPO2 will be measured before and after the intervention. A second control group with type 2 diabetes will also have TcPO2 levels measured before and after the 12 weeks of the study.

Detailed Description

Objective: To determine the effect of whole body vibration exercise on levels of TcPO2 measured in the feet of patients with type 2 diabetes, in order to create recommendations for prevention of diabetic foot.

Material and Methods: controlled open clinical trial consisting in 2 arms, as follows: 1) control group under care for type 2 diabetes, and 2) intervention group, who, in addition to the standard care, will undergo an exercise program of whole body vibration three times a week, with progressive intensity, for a period of 12 weeks. Partial pressure of transcutaneous oxygen (TcPO2) will be measured in the feet of the participants at baseline and after 12 weeks, with 40 patients per group.

Statistical analysis: demographic information of the subjects will be described as arithmetic means, standard deviation, percentages, frequencies. Comparison between groups will be done with Student t for independent data or Mann-Whitney U when convenient. Baseline and final measurements will be compared. inter and intra group comparisons will be made by repeated measurements. For qualitative values, chi square will be used. Multivariate analysis will be performed to control for confounding variables. The level of significance will be a value of 0.05.
