After a clinical study, American researchers have found that regularly doing tai-chi is an effective treatment in fighting knee arthrosis.
Forty elderly patients, averaging 65 years of age, participated in this study. They were tested on the intensity of their pain and their level of physical inability during the beginning of the study and again after three months, six months and after a year.
For forty-eight weeks, twenty people did tai-chi while others proceeded to do stretching exercises and received nutritional instruction and theory education on the disease.
Among the people having devoted themselves to tai-chi, the pain felt was reduced by 75%, compared to only 13% for the other group. Moreover, their functional handicap was 4.6 times less present.
The biological mechanism provoked in doing tai-chi is unknown, but it is believed that the slow movements improve muscular tone and the joints. Furthermore, the slowness, concentration and the necessary relaxation in tai-chi helps improve chronic pain.
