People with Parkinson's Disease tend to have impaired balance, and an increased risk of falling. A clinical trial assessed the effect of Tai Chi on postural control in Parkinson's Disease. Tai Chi is a traditional Chinese martial art and form of exercise. For more information go to Tai Chi.  Participants took part in 60-minute exercise sessions twice weekly for 24 weeks. Although the researchers claimed that Tai Chi performed consistently better than other methods, the improvement was only 5% better than resistance training, and 12% better than stretching exercises. The Tai Chi group performed better than the stretching group in all secondary outcomes and outperformed the resistance-training group in stride length and functional reach. Tai Chi lowered the incidence of falls when compared with stretching exercises but not when compared with resistance training.
