5. Study Description

Brief Summary
Whole body vibration (WBV) has been found to be useful in promoting bone health and muscle performance in older adults. To date, no study has examined the effects of different WBV frequencies on the properties of the muscle-bone unit in stroke patients. The overall aim of the proposed study is to compare the efficacy of different vibration frequencies on properties of the muscle function and bone turnover among people with chronic stroke. It is hypothesized that the higher-vibration frequency protocol will lead to significantly better outcomes related to the bone turnover and muscle function.
