September issue of Clinical Rehabilitation.
safety and feasibility of a 12-week Tai Chi intervention among stroke survivors.
Two-group, prospective pilot study with
Outpatient rehabilitation facility.
Stroke survivors >=50 years and at >=three
Tai Chi subjects attended group-based Yang
Style classes three times/week for 12-weeks, while Usual Care subjects received
weekly phone calls along with written materials/resources for participating in
community-based physical activity.
Indicators of study safety and feasibility
included recruitment rates, intervention adherence, falls or adverse events,
study satisfaction, drop-outs, and adequacy of the outcomes measures.
Interested persons pre-screened by phone (n = 69) were on average
68 years old, (SD = 13) years old, 48% (n = 33) women, 94% (n = 65) were at
least three months post-stroke. A total of 28 subjects aged 69 (SD = 11) years
enrolled in this pilot study. Intervention adherence rates were very high. There were no falls or other adverse events. The dose of Tai Chi
exercise (>=150 minutes/week) was well tolerated. Overall study satisfaction was
high (8.3 (SD = 1.9); 1 = not satisfied, 10 = most satisfied), while drop-outs
(n = 3, 11%) were unrelated to study intervention. Score distributions for the
outcome measures were approximately normal, sensitive to change, and seemed to
favor the Tai Chi intervention.
Tai Chi is a safe, community-based exercise program for stroke survivors. Our data
suggest that recruitment and retention of an adequate sample is feasible, and
that in a full-scale study 52 subjects/group are needed to detect statistically
significant between group differences (alpha = 0.05, power = 0.80).
