Tai Chi class boosts shingles immunity

Tai Chi class boosts shingles immunity

UCLA Neuropsychiatric Institute researchers report that older adults in a 15-week Tai Chi class saw immunity factors that suppress shingles soar 50 percent. In addition, participants showed significant improvement in their physical health and ability to move through their day.

Appearing in the September edition of the journal Psychosomatic Medicine, findings of the randomized, controlled clinical trial are the first to demonstrate a positive, virus-specific immune response to a behavioral intervention.

“Our findings offer a unique and exciting example of mind over matter,” said Dr. Michael R. Irwin, a professor at the UCLA Neuropsychiatric Institute and director of the Institute’s Cousin’s Center for Psychoneuroimmunology. “A large body of research shows how behavior can negatively affect the immune system and health, but ours is the first randomized, controlled study to demonstrate that behavior can have a positive effect on immunity that protects against shingles. The findings are particular noteworthy as Tai Chi Chih or ‘meditation with movement’ increased immunity in older adults who are at risk for herpes zoster.

“The improvements in both immunity and physical functioning were significant by widely accepted measures of each, and all with no surgery, no drugs and no side effects,” Irwin said. “We were particularly struck by improvements in what subjects were able to accomplish physically as a result of participating in these classes. In fact, older adults who had more impairment present at the start of the study showed the greatest improvement and benefit at the end.”

The varicella zoster virus, or shingles, can cause a painful skin rash with intermittent pain that can last for months or years. Even when the rash subsides, skin in the affected area can remain extremely painful to the touch.

The virus lurks in the nerves of virtually everyone who has had chicken pox, but the immune system typically prevents outbreaks. This cell-mediated immunity to the virus declines with age, however, leaving older adults particularly susceptible to the painful condition. The greater the decline, the greater the risk. No vaccination against shingles exists.

The study randomly assigned 36 men and women age 60 or older to a 15-week program of three 45-minute Tai Chi classes a week or to a wait list. To qualify, each volunteer had to show immunity to varicella zoster virus, but not to have had a history of shingles. They also had to be able to walk. Three class members dropped out before the study ended due to transportation issues. One member of the control group dropped out.

The class used a highly structured variety of the martial art called Tai Chi Chih, which is specially designed for easy use by older adults.

Varicella zoster virus-specific, cell-mediated immunity was measured before the program began and one week after the program ended. Doctors used the Medical Outcome Scale to assess physical functioning before the program began; at five, 10 and 15 weeks during the program; and one week after the program ended.
