Study Overview
Brief Summary
The whole body vibration exercise group will have significantly more improvement in mobility, muscle strength, balance, balance confidence, and cognitive function with a lower fall rate than the control group.

Arms & Interventions
Whole body vibration exercise
The experimental group will receive 2 sessions of whole body vibration exercise training and conventional exercise per week for a period of 9 weeks. The total duration of vibration exposure per session will range from 4 to 6 minutes. The vibration frequency and amplitude used will be 30 Hz and 1 mm, respectively.
Intervention: Whole body vibration exercise (Device)
