Tai Chi Shows Promise as a Stroke Therapy
Quote:
Stroke patients who practice tai chi may improve their balance — reducing the risk of falls, researchers say.
Writing in the journal Neurorehabilitation and Neural Repair, the researchers reported improvement in volunteers after as little as six weeks of training. The lead author was Stephanie S. Y. Au-Yeung of Hong Kong Polytechnic University.
In earlier research, one of the article’s co-authors, Christina W. Y. Hui-Chan, found that tai chi improved balance among healthy elderly people. For this study, the researchers wanted to see if the same effect would occur among stroke patients.
They took 136 people who had a stroke six months or more earlier and divided them into two groups. Over 12 weeks, one group did general exercise, the other a modified version of tai chi.
The tai chi group met once a week for an hour, and were asked to practice at home about three hours a week.
While the exercise group showed little improvement in balance, the tai chi group made significant gains when they were tested on weight-shifting, reaching and how well they could maintain their stability on a platform that moved like a bus.
The benefit of tai chi, the researchers said, is that once the forms are mastered, they can be done without supervision.
Still, they said, some patients lapsed in their practice after the training was over. They might be more likely to continue, the study said, if tai chi were available at places like community centers.
