Estimated Study Completion Date: October 2015
Estimated Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Whole body vibration
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
The vibration frequency and amplitude used will be 30-40 Hz and 1mm, respectively. The total exposure to the vibration stimulation is 4 minutes.
Active Comparator: Conventional exercise
This group will receive convention exercise training (1 hour per session, 3 sessions per week, for 8 consecutive weeks).
Behavioral: Conventional exercise
The conventional exercise training involves upper limb and lower limb strengthening exercises using sandbags.
Active Comparator: Control
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
The control treatment involves exercises of the upper limbs.
