“…As with the game technology used, there was a wide variety in exercise games. For the 35 studies using Nintendo Wii, two studies used only the Wii Sports bowling game (34,55), while the remaining 33 studies used two or more games during the intervention. Furthermore, 11 of the Nintendo Wii studies used games that targeted balance only (11, 35, 37, 42-44, 47, 57, 58, 73, 82), while 16 used a combination of games that targeted different physical functions in addition to balance, such as strength, endurance, and mobility (10,13,32,40,45,49,52,56,60,69,70,74,77,80,81,86).…”
