Results from the Central Sydney Tai Chi Trial
The objective was to determine the effectiveness of a 16-week community-based tai chi program in reducing falls and improving balance.
First, the details.
- 702 relatively healthy community-dwelling people aged 60 and older and living in Sydney, Australia participated.
- They were assigned to either a program of community-based tai chi or to a wait list.
- Classes were of 1-hour duration per week.
And, the results.
- Falls were significantly less frequent in the tai chi group vs the control group at 16 and 24 weeks.
- The tai chi program had no effect on the proportion of people who had one or more falls during follow-up.
- But tai chi appeared to reduce the proportion of participants who had two or more falls.
- There were statistically significant differences in changes in balance favoring the tai chi group on 5 of 6 balance tests.
The bottom line?
As in an earlier study, it seems that weekly community-based tai chi classes can reduce falls in relatively healthy, community-dwelling older people.
However, according to the authors, “A weakness of this study is that … differences in physical activity between the tai chi and the control group could not be adequately controlled for. Another limitation was that nearly 30% of participants did not complete the follow-up balance assessments.”
