A case of arm swelling and muscle Wii-kness.

The Nintendo Wii is now the world's most popular home games console owing to its simple interface and replication of sports activities. Although safety advice is provided by the manufacturer, a number of injuries have previously been described. We describe a case of arm swelling with associated rise in serum creatine kinase to over 8000 U/L in a man, following unaccustomed and sustained strenuous muscle exertion through the use of the Nintendo Wii. His condition spontaneously resolved with rest and conservative measures. His presentation represents significant muscle injury through the use of this games console and the replication of sporting activities; physicians should be aware of the variety of musculoskeletal presentations such use of these devices can produce.
