(Player using Wii Fit for yoga.)
Most hospitals are using the Wii as a rehabilitation tool because it involves patients moving their arms and bodies for different activities. While most Wii games involve players moving their arms, the "Wii Fit" is another peripheral for the Wii that can also be used as a rehabilitation tool. The Wii Fit Balance Board is a peripheral that allows players to use their body to control the character on the screen by tilting their bodies while standing on the board. Most games use this to utilize an extra form of control, but it can also teach players a variety of exercises.
At the Ohio State University Waxner Medical Center, doctors and researchers asked patients to use the Wii Balance Board to do yoga exercises, and atheletic trainer Tamerah Hunt, Ph. D has used it as an assessment tool. She uses it to determine the extent of damage that concussions have on patients by analyzing lateral sway, anterior sway, and center of gravity. The stances that have been used are the single leg stance, double-leg stance, and tandem stances for their assessments, which can be charted to track pogress. With the Wii Fit, hospitals are able to use a tool that is both effective and is less expensive than most machines.
