The half of the group participated in at least four weekly sessions of tai-chi of one hour, during 16 weeks. To compare the effect of the tai-chi, the researchers asked the participants of the second group to maintain their usual frequency of exercise.
According to the results of the tests done, there was an improvement of 36% of the sensation of the movements of bending and 25% of the extension of the knee in the tai chi group, against an improvement of 14% and 5% in the second group.
