简要总结
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.

研究组 & 干预措施
High frequency whole body vibration
This group will receive a single 8-minute session of WBV therapy. The frequency of the vibration signals will be set at 30Hz.
干预措施: High frequency whole body vibration (Procedure)
low frequency whole body vibration
This group will receive a single 12-minute session of WBV. The frequency of the vibration signals will be set at 20 Hz.
干预措施: Low frequency whole body vibration (Procedure)
