简要总结
Whole body vibration has been found to be useful in promoting bone health, balance, and muscle performance in older adults. The overall aim of the proposed study is to determine whether whole body vibration (WBV) has immediate beneficial effect in neuromotor performance in patients with stroke. It is hypothesized that a single session of WBV will induce significant improvement in leg muscle strength in people with chronic stroke.

研究组 & 干预措施
High frequency whole body vibration
This group will receive a single 10-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 10-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)
Control
This group will stand on the same vibration platform for 10 minutes, but no vibration will be given.
干预措施: control (Procedure)
