Brief Summary

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

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.

Study Groups

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

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.

Group Type EXPERIMENTAL

Whole body vibration exercise

Intervention Type DEVICE

The whole body vibration will be delivered by a platform that can generate vibration signals (Powerplate). The total duration of vibration exposure per session will range from 4 to 6 minutes. The vibration bouts (30-45 seconds per bout) will be interspersed with a 1 to 2 minutes of rest period. While standing on the vibration platform, subjects will be instructed to repeat two exercises: (1) static semi-squats, and (2) dynamic semi-squats.

Conventional exercise

Intervention Type BEHAVIORAL

The conventional exercise training will involve a combination of upper limb and lower limb stretching and strengthening exercises, balance training, and gait re-education.

Conventional exercise

This group will receive 2 sessions of conventional exercise training per week for a period of 9 weeks.

Group Type ACTIVE_COMPARATOR

Conventional exercise

Intervention Type BEHAVIORAL

The conventional exercise training will involve a combination of upper limb and lower limb stretching and strengthening exercises, balance training, and gait re-education.
