of Iowa, Claremont Graduate University and Lanzhou University of China, was to
systematically review the effectiveness of tai chi for reducing depressive

were searched through January 2011. Reference lists of systematic reviews and
identified studies from the search strategy were also screened. Randomized
controlled trials of tai chi compared with waiting list controls in older adults
with depressive symptoms measured by a self-report depression rating scale were
independently identified eligible studies, extracted data and assessed the
included studies for risk of bias. Estimates of depressive symptoms reduction
used a random effects model, and the I(2) statistic was applied to examine
heterogeneity. Four trials with a total of 253 participants met the inclusion
criteria. Two studies were assessed as being of high quality; the remaining two
studies were rated as moderate quality. All four studies compared tai chi with a
waiting list control group.
Tai chi appeared to
have a significant impact on reducing depressive symptoms compared with the
waiting list control groups. Further research is recommended with larger sample
sizes, more clarity on trial design and the intervention, longer-term follow up,
and concomitant economic evaluations.
