Whole Body Vibration Exercise Training for Institutionalized Elderly

Study Overview
=================
Brief Summary
-----------------
It is hypothesized that whole body vibration exercise group will have significantly more improvement in physical functioning and reduction in fall incidence among institutionalized elderly, compared with conventional exercise group and control group.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Whole body vibration<br>This group will receive whole body vibration and conventional exercise training (1 hour per session, 3 sessions per week, for 8 consecutive weeks). | Device: Whole body vibration<br>* The vibration frequency and amplitude used will be 30-40 Hz and 1mm, respectively. The total exposure to the vibration stimulation is 4 minutes.<br>|
| Active Comparator: Conventional exercise<br>This group will receive convention exercise training (1 hour per session, 3 sessions per week, for 8 consecutive weeks). | Behavioral: Conventional exercise<br>* The conventional exercise training involves upper limb and lower limb strengthening exercises using sandbags.<br>|
| Active Comparator: Control<br>This group will have exercise training that involve only the upper limbs (about 30 minutes per session, 3 sessions per week, for 8 consecutive weeks). | Behavioral: Control<br>* The control treatment involves exercises of the upper limbs.<br>|
