Parkinson’s symptoms better by playing Nintendo Wii

Parkinson’s disease is a degenerative disease that impairs motor skills. The Nintendo Wii may help treat symptoms of Parkinson’s disease, including depression, a Medical College of Georgia researcher says.

Dr. Herz theorized that the popular computer game console, which simulates various sports and activities, could improve coordination, reflexes and other movement-related skills, but he found additional benefits as well.

“The Wii allows patients to work in a virtual environment that’s safe, fun and motivational,” says Dr. Ben Herz, program director and assistant professor in the School of Allied Health Sciences Department of Occupational Therapy. “The games require visual perception, eye-hand coordination, figure-ground relationships and sequenced movement, so it’s a huge treatment tool from an occupational therapy perspective.”

In an eight-week pilot study, 20 Parkinson’s patients spent an hour playing the Wii three times a week for four weeks. The patients, all in a stage of the disease in which both body sides are affected but with no significant gait disturbance yet, played two games each of tennis and bowling and one game of boxing-games entailing exercise, bilateral movement, balance and fast pace.

Participants showed significant improvements in rigidity, movement, fine motor skills and energy levels. Perhaps most impressively, most participants’ depression levels decreased to zero.

An estimated 45 percent of Parkinson’s patients are reported to suffer from depression, though Dr. Herz suspects the actual figure is much higher.

Studies have shown that exercise and video games independently can increase the production of dopamine, a neurotransmitter deficient in Parkinson’s patients. He suspects that’s the case with the Wii’s exercise effect. Dopamine also helps improve voluntary, functional movements, which Parkinson’s patients “use or lose,” Dr. Herz says.

Wii, which features simulated movements such as cracking an egg, swinging a tennis racket and throwing a bowling ball, responds to a player’s movements rather than cues from a controller, so players can do full body movements and see their progress on a screen.

“I think we’re going to be using virtual reality and games a lot more because it provides a controlled physical environment that allows patients to participate in the activities they need or want to do. A patient doesn’t have to go to a bowling alley and worry about environmental problems or distractions,” Dr. Herz says.

Dr. Herz presented his preliminary findings at the fifth annual Games for Health Conference in Boston.
