PMID 29510972WHAT IT FOUND
An adapted Wii Fit Balance Board let all 25 participants with mobility impairments play, including 13 who could not use the original board.
They rated it good overall and excellent among those who could not use the original board.
Key findings
01Twenty-five participants completed usability ratings, and all 25 could use the adapted board.
02Thirteen participants, all assistive aid users, could not use the original Wii Fit Balance Board.
03The adapted board had a mean System Usability Scale score of 71.7, rated good, and a mean score of 75.96 among participants who could not use the original board, rated excellent.

What it does not show
The study included 25 participants and measured usability, so it does not show that the adapted board increases physical activity, balance, or health outcomes. Thirteen participants could not use the original board, so its usability could be rated only by the 12 participants who could use it. The adapted board included several design changes, so the contribution of any single feature cannot be separated. The sample included many different impairments and assistive aids, so results may not apply to one specific group. The prototype had a maximum weight of 150 kg (330 lb) for the player and wheelchair. The sensitivity control was not evaluated in this study.

No conflicts of interest were declared.
The easy way to misread this
Do not conclude that the adapted board increases physical activity, balance, or health. It tested subjective usability, not those outcomes, and only 12 participants could use the original board.
