Current limitations of the Wii's validity and what should be considered for the future

摘要

The letter by Pagnacco and colleagues provides a timely critique of an article that is quickly becoming a standard citation justifying the Nintendo Wii Balance Board (WBB) for balance assessment. Over 100 studies have cited Clark and colleagues' article examining the Nintendo Wii for standing balance assessment [1,2]. However, I believe some of the conclusions made by Clark et al. are leading to poor use of the Wii for balance assessment. The intent of this letter is to present three issues that I perceive are being overlooked or ignored by researchers and clinicians using the Wii: the COP measure used to validate the Wii, the difference between exporting COP and using Nintendo games for balance assessment, and consideration of the underlying motor control mechanisms for postural stability.
