Wii Balance Board To Determine Center of Pressure
Though originally designed as a video game controller, the Balance Board has become a proven tool for assessing center of pressure displacement. It is proven to be both valid and reliable. Clark et al. performed a study to prove the validity and test-retest reliability of the use of a WBB. The idea behind using a WBB instead of a force platform is the ability to “create a portable, inexpensive balance assessment system that has widespread availability.” Four standing balance tasks were used in this study including a combination of double stance, single stance, eyes open, and eyes closed. Throughout these tests the center of pressure path length was measured and compared these data to an identical study on a laboratory-grade force platform. The study found the Wii Balance Board to be both valid and have high test-retest reliability.

“The most perfect political community must be amongst those who are in the middle rank, and those states are best instituted wherein these are a larger and more respectable part, if possible, than both the other; or, if that cannot be, at least than either of them separate, so that being thrown into the balance it may prevent either scale from preponderating.”
