At a follow-up visit 3 months after the intervention was over, the patients in the tai chi group maintained these gains in stability and mobility, and continued to have fewer falls than did those in the other two groups.
"No serious adverse events were observed during tai chi training, indicating the safety and usefulness of this intervention for persons with Parkinson’s disease," Dr. Li and his associates wrote.
This study was supported by the National Institute of Neurological Disorders and Stroke. The investigators had no financial conflicts of interest to report.
