The Wii is the top selling video system.
Games like bowling and golf can be beneficial and help some people stay active. But doctors say they say are seeing an increase in injuries linked to the gaming system. In fact, they now have two medical terms for these injuries, "Wii syndrome" or "Wii-itis."
College freshman Ashley Propes knows all about Wii-induced injuries. She heard a pop in her wrist as she was playing, and the swelling was so bad, she says she couldn't even take notes in class.
"They need to treat it as it's any physical activity, they need to stretch before they Wii, clear their environment before, watch you where you Wii, clear the environment so you avoid hitting themselves, striking the sofa, striking other players," said Dr. Shawn Mansour, orthopedic trauma surgeon.
To prevent injuries. doctors say you should take 10 to 15 minute breaks every hour. and you should stop playing if you feel any tingling or numbness. If pain and swelling persist you should see a doctor.
