Effects of T'ai Chi on balance

Objective: To determine if the practice of Tai Chi significantly improves b alance. Methods: Twenty-two persons with mild balance disorders were studied. Five measures of balance were obtained, including 3 objective measures (moving p latform posturography, Romberg testing, and reach testing) and 2 disability questionnaires (Dizziness Handicap Inventory and a modified Medical Outcom es Study general health survey). To be included, patients were required to be able to stand in the eyes-closed regular Romberg position for 30 seconds . The subjects underwent 8 weeks of T'ai Chi training and practice and then were retested. Results: Highly significant improvements were found on both the posturograp hy test and the Dizziness Handicap Inventory questionnaire scores (P < .001 and P = .004, respectively). Trends toward improvement were also noted in Romberg test results and the Medical Outcomes Study survey (P = .03 for bot h). Reach was not improved. Conclusion: These findings suggest that T'ai Chi training improves balance.
