Whole body vibration has been shown to reduce the pain and disability associated with Osteoarthritis. 

Exercise can reduce pain and disability by decreasing muscle inhibition and by improving local circulation.  Unfortunately, most osteoarthritis sufferers tend to not adhere to an exercise regimen due to the discomfort associated with working out.  The more difficult the exercise, the less likely they will do it.  Whole Body Vibration (WBV) is particularly suited for these people because it exercises the postural system. 

WBV is easy to use, the exercise sessions are short and best of all it is safe.
