Playing Video Game May Boost MS Patients' Balance
Research suggests regular use of Wii accessory might rewire the brain

TUESDAY, Aug. 26, 2014 (HealthDay News) -- An exercise component of the popular Nintendo Wii video game may help multiple sclerosis patients improve their balance by rewiring their brains, a new study suggests.
No medications exist to preserve balance in MS patients, and some drugs make balance worse, said study lead author Dr. Luca Prosperini, a neurologist at Sapienza University in Rome, Italy.
It appears that patients who use the Wii Balance Board five days a week -- moving to snowboarding or dance games, for example -- may help reduce their risk of falls and boost certain brain connections, possibly because they're coordinating their movements with a figure on a screen, Prosperini said.
There are caveats to the research, however. The study was small, and there's a risk that patients could hurt themselves by falling, although they can play seated rather than stand on the balance board.
"Patients with MS should be encouraged to start using this system only under supervision," Prosperini said. "Once well-trained, they may use it at home."
Multiple sclerosis is a nerve disorder that affects how the brain communicates with the body.
"Balance problems are quite common and arise due to the effects of MS on a number of functions that are important for balance," said Nicholas LaRocca, vice president for health care delivery and policy research with the National Multiple Sclerosis Society. Among other things, MS can disrupt vision, coordination and the body's balancing mechanism, he said.
Patients turn to a variety of strategies to support balance, he said. Canes and orthotic devices (shoe inserts) help some people, and rehabilitation can build strength and coordination. Some patients try electrical muscle stimulation to maintain or regain control of their muscles, he said.
Prosperini was inspired to study a video game treatment for MS when he saw patients in rehabilitation using a balance-boosting system that reminded him of an old Atari video game. Then a commercial about the Wii Balance Board caught his attention. The balance board, shaped a bit like a weight scale, detects a person's movements and allows them to be translated into action on a TV screen.
Prosperini tried to get a grant from Nintendo to support research. The company wasn't interested, he said, but he obtained funding from the Italian MS Society.
His previous research has supported the idea that patients regain balance when they use the Wii Balance Board. The new study aimed to understand what's happening in their brains.
In the new study, published online Aug. 26 in Radiology, 27 MS patients were split into two groups. One group spent three months doing nothing special while the other group played with the Wii Balance Board for 30 to 40 minutes daily, five days a week. Then the groups reversed roles: Those who had done nothing special used the balance board for three months, while the others stopped using it.
