Response to letter to the editor: On 'Comparison of a laboratory grade force platform with a nintendo wii balance board on measurement of postural control in single-leg stance balance tasks' by Huurnink, A., et al. [J. Biomech. 46 (2013) 1392-1395]: Are the conclusions stated by the authors justifiedα

摘要

We thank Pagnacco and colleagues for their interest in our work, but we have to disagree with their conclusions. Below we will argue that the rhetorical question in the title of their letter can be answered in the affirmative. Pagnacco and colleagues raise concerns about the methodology of our study, and even claim that the conclusions offered are misleading and unsupported. We agree that the two devices (laboratory grade force plate (FP) and Wii Balance Board (WBB)) cannot be considered interchangeable, but this is not what we state in our paper. In fact, the limitations of the WBB are extensively presented and discussed in the paper. We did, however, conclude that the WBB is sufficiently accurate to be used for sway measures of single-leg stance, as used in the field of sports medicine and sports rehabilitation. Although not exactly equal, the center of pressure (CoP) measurements with the WBB were shown to provide very good proxies for parameters derived from more accurately measured CoP data. For more information about the specifications and durability of the WBB, we would like to advise the recent work of Bartlett et al. (2014).
