March 8, 2004 -- Practicing the traditional Chinese martial art
of tai chi appears to offer both mental and physical benefits for people with
chronic diseases, but researchers aren't exactly sure what those benefits
A new review of studies on tai chi shows that the practice is
safe and probably beneficial for older adults with conditions such as heart
failure, high blood pressure, arthritis, and multiple sclerosis. It may also

in balance and strength, cardiovascular and respiratory function, flexibility,
immune function, and symptoms of arthritis. Psychological benefits in reducing
stress and anxiety were also reported.
But only nine of the studies reviewed were randomized and
controlled, which is the highest standard for scientific research, and all of
them were short-term.
"Therefore, the long-term effects of tai chi practice are
still unknown, and there is insufficient information to recommend Tai Chi to
patients with chronic conditions," conclude the researchers.
