Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    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.”
