An Oregon Research Institute (ORI) exercise study conducted in four Oregon cities has shown significant benefits for patients with mild-to-moderate Parkinson's disease. In an original article published in the February 9, 2012 issue of the New England Journal of Medicine (NEJM), ORI scientist Fuzhong Li, Ph.D. and colleagues report that a tailored program of twice-weekly Tai Chi training resulted in improved postural stability and walking ability, and reduced falls in the participants.
"These results are clinically significant because they suggest that Tai Chi, a low-to-moderate impact exercise, may be used, as an add-on to current physical therapies, to address some of the key clinical problems in Parkinson's disease, such as postural and gait instability. Since many training features in the program are functionally oriented, the improvements in the balance and gait measures that we demonstrated highlight the potential of Tai Chi-based movements in rehabilitating patients with these types of problems and, consequently, easing cardinal symptoms of Parkinson's disease and improving mobility, flexibility, balance, and range of motion," noted Dr. Li.
