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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| High frequency whole body vibration | Experimental | This group will receive a single 10-minute session of WBV therapy. The frequency of the vibration signals will be set at 30Hz. |
|
| low frequency whole body vibration | Active Comparator | This group will receive a single 10-minute session of WBV. The frequency of the vibration signals will be set at 20 Hz. |
|
| Control | Active Comparator | This group will stand on the same vibration platform for 10 minutes, but no vibration will be given. |
