Ageing is associated with changes in body balance mechanism. The gold standard assessment for body balance is posturography. However, because of the high cost constraints, not many health centers are equipped with the equipment. Nintendo Wii balance board (WBB) has been reported as a potential tool to be used to assess body balance and sway. Also, because WBB is more economical and portable, it has greater potential to be used in primary health centers and community settings. The objective of this study was to compare balance measures using BRU™ and WBB among young and older healthy adults during quiet standing. Thirty three young (26.9±5.6 years) and 33 older adults (65.6±4.4 years) were randomly tested on both equipments. Subjects performed 30sec trial for each of the four testing conditions: quiet standing on a firm or compliant surface (foam) with eyes-open and closed. The results showed significant differences in balance measurements between all four testing conditions and age groups using both equipments.This study also found significant positive correlations between the COPand sway velocity, SV (of the BRU™) and COB (of the WBB) in all test conditions. These results indicated that WBB coupled with its commercially available software could potentially be used as a screening tool for balance assessment in primary health centres.
