Effect of tai chi on physical function, fall rates and quality of life among older stroke survivors

How many decades is it going to take to get Tai Chi as a stroke protocol in all stroke hospitals? Unless YOU push this it will be at least 50 years.

Abstract: Study examined the effect of a 12-week Tai Chi (TC) intervention on physical function and quality of life. A total of 145 community-dwelling survivors of stroke, aged 50 years or older, were randomly assigned to: (1) Yang style 24-posture short-form TC; (2) Silver Sneakers (SS), a program of strength and range of movement exercises for older adults; or (3) usual care (UC) for 12 weeks. The TC and SS groups attended a 1-hour class 3 times per week, whereas the UC group had weekly phone calls. Physical function was evaluated using the Short Physical Performance Battery, fall rates, and the 2-minute step test. Quality of life was assessed using the Medical Outcomes Study 36-Item Short-Form Health Survey, Center for Epidemiologic Studies Depression Scale, and Pittsburgh Sleep Quality Index. During the intervention, TC participants had two-thirds fewer falls (5 falls) than the SS (14 falls) and UC (15 falls) groups. There was a significant group-by-time interaction for the 2-minute step test. Post hoc tests indicated that the TC and SS groups had significantly better aerobic endurance over time, though not in the UC group. Intervention adherence rates were 85 percent. TC and SS led to improved aerobic endurance, and both are suitable community-based programs that may aid in stroke recovery and community reintegration. Results suggest that a 12-week TC intervention was more effective in reducing fall rates than SS or UC interventions. Future studies examining the effectiveness of TC as a fall prevention strategy for community-dwelling survivors of stroke are recommended.
