Tai chi, an ancient martial art characterized by slow, flowing movement and meditation, helps improve balance and movement control for people with Parkinson’s disease.
The finding, published in The New England Journal of Medicine, is the latest study to show the benefits of tai chi for people with chronic health problems. Past studies have shown that tai chi reduces falls and depression among the elderly, and lessens pain for patients with arthritis and fibromyalgia.
In Parkinson’s disease, nerve cells in the brain that produce the chemical dopamine begin to die. Lower dopamine production can lead to tremors, balance problems, stiff facial expressions and muffled speech, among other problems.
An estimated one million people in the United States have the disease, and another 60,000 receive the diagnosis each year. Although the condition usually develops after the age of 60, 15 percent of those who learn of the diagnosis are under 50.
In the latest research, 195 people with movement and balance problems caused by Parkinson’s disease were recruited from four Oregon cities. The patients were divided into three exercise classes that met for an hour a day, twice a week. One group took part in an extensive stretching class, another was taught resistance training, and the third group performed tai chi.
After six months, patients in the tai chi group performed better on a number of measures related to strength, movement control, balance, stride length and reach. Resistance training also offered some benefits, and both the tai chi and resistance training groups had fewer falls than the stretching group.
