The document discusses using the Nintendo Wii for physical and occupational therapy treatments. Studies show the Wii can improve balance in children with Down syndrome ages 10-13 when playing games like soccer heading and tightrope walking for 6 weeks. The Wii also improved static and dynamic balance in children ages 7-12 with poor motor skills when playing balance games for 30 minutes 3 times a week for 6 weeks, but did not transfer skills to other motor tasks. Research also found the Wii can improve upper extremity function in children with cerebral palsy ages 6-15 when playing tennis and boxing games twice a week for 15 minutes each. While the Wii is low cost and enjoyable, its balance measures are not always valid or reliable
