Attempts at identifying the root cause     2     Parkinson’s and battling against its effects are increasing. Tai Chi, which patients with Parkinson’s disease can practice     3     (they), has been proved to be a simpler way to help. Previous studies showed short-time practice of Tai Chi brought benefits.
