This study is performed by National Taiwan UniversityThis study is performed by the Hong Kong Polytechnic University in a University clinic in USA. It aimed to address one question: Does Tai Chi improve postural control in patients with Parkinson's disease?

Individuals with Parkinson's disease between the age of 40 and 85 years, and ability to walk with or without an assistive device were key inclusion criteria. Mini-Mental State examination score <24 and concurrent participation in other instructor-led exercise programs were key exclusion criteria. Randomization of 195 participants allocated 65 to each of the Tai Chi, resistance, and stretching groups.

The Tai Chi group underwent a Tai Chi program, the resistance group 8 to 10 leg muscle strengthening exercises, while the stretching group performed stretching exercises involving the upper body and lower extremities. All three groups trained for 24 weeks (60 minutes per session, two sessions per week).

The primary outcomes were two indicators of postural stability - maximum excursion and directional control derived from dynamic posturography. The secondary outcomes were stride length, gait velocity, knee flexion and extension peak torque, functional reach, timed-up-and-go test, and motor section of the Unified Parkinson's Disease Rating Scale (UPDRS III). The outcomes were measured at baseline, at 12 and 24 weeks, and 3 months after termination of the intervention.

One hundred eighty-five participants completed the study. At the end of the 24-week training period, the change in maximum excursion in the Tai Chi group was significantly more than that in the resistance group and the stretching group. Direction control improved significantly more in the Tai Chi group compared with the resistance group and the control group. The Tai Chi group also had significantly more improvement in stride length and functional reach than the other two groups. The change in knee flexion and extension peak torque, timed-up-and-go test, and UPDRS III score in the Tai Chi group was only significantly more than that in the stretching group, but not the resistance group. The falls incidence was also lower in the Tai Chi group than the stretching group during the 6-month training period.

The research concluded that Tai Chi training is effective in reducing balance impairments in patients with mild to moderate Parkinson's disease.
