Abstract
Introduction
Although often classified as a motor skill, standing balance relies on three sensory systems: vestibular, proprioception, and visual. To assess balance by challenging these systems, the rater uses the Modified Clinical Test of Sensory Integration and Balance (mCTSIB). However, valid low-cost equipment is unavailable for continuous patient monitoring.
Objective
The aim of the present study was to assess the validity of the Wii balance board (WBB) compared to a standard force platform during the mCTSIB.
Methods
A sample of 50 participants (17 men and 33 women; 23.34 [3.10] y; 1.68 [0.08] m; 68.82 [13.55] kg) was included. The average total COP displacement was simultaneously collected during standing balance from both WBB and the force platform under four conditions: eyes opened and closed with and without a foam cushion.
Results
No significant differences were observed between the WBB and the force platform. The correlation was considered high (r > .98; p = .001), with excellent adjusted coefficients of determination (.97 < r2 < .99). The Bland–Altman method revealed low bias, and the majority of the results were scattered between the lower and upper levels of agreement.
Conclusions
The present findings suggest the validity of the WBB to assess the balance during the mCTSIB.
