Improving Fall Risk with
Whole Body Vibration Exercise
Balance deficit is one of the leading causes of falls in the elderly. A number of studies have shown that whole body vibration (WBV) training can improve lower extremity strength and balance in elderly subjects. This study took a novel approach by randomizing elderly sedentary subjects into three groups:
Group 1 performed WBV exercise with eyes open
Group 2 performed WBV exercise while blindfolded
Control group performed the exercise without any vibration
All groups held a semi squat position for 5 minutes. This exercise was performed 3 x per week for 3 months. No other lifestyle changes were made.
At the end of the study both the WBV training groups had improved strength (Isokinetic dynamometry of the knee flexors and extensors) and balance (Limits of Stability test) compared to the group who exercised with eyes open with no vibration. The blindfolded group showed the greatest gains. (all p
At 6 month follow-up the incidence of falls in both WBV training groups was 0% and in the control group the fall incidence was 28.57% (similar to the 30% average fall rate in the general population over 65 years old).
This study was interesting because it was the first to eliminate visual feedback during WBV training. It is well known that eyes closed balance is significantly more difficult and that this type of training may be beneficial by forcing the body to adapt to increases in postural sway. We can incorporate eyes closed training to the vibration platform as well.
