Following on from the December 2007 BMJ article Comparison of energy expenditure in adolescents when playing new generation and sedentary computer games: cross sectional study is a new study reported in the UK’s Guardian:

Dexterity boost from games consoles hones surgery skills

Update: A letter in today’s BMJ reports:

“In the first clinic after Christmas we encountered a child who was complaining of tiredness and a sore shoulder, having been inactive over the past three years through illness. He had been given a new generation computer game for Christmas, and having checked everything else, we diagnosed Wii shoulder.

Anyone who has played interactive games on Wii sport will relate to this shoulder pain in muscles that have not been used for a long time. Within a day the discomfort wears off, as with exercise after a period of inactivity.”
