Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

High frequency whole body vibration

Intervention Type PROCEDURE

1 single session (10 minutes) of whole body vibration therapy at 30 Hz

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.

Group Type ACTIVE_COMPARATOR

Low frequency whole body vibration

Intervention Type PROCEDURE

1 single session of whole body vibration therapy at 20 Hz

Control

This group will stand on the same vibration platform for 10 minutes, but no vibration will be given.

Group Type ACTIVE_COMPARATOR

control

Intervention Type PROCEDURE

1 single session of standing on the vibration platform, with no vibration signals delivered.
