Abstract: | [Purpose] The purpose of this study was to determine the concurrent validity of Wii Fit center-of-pressure parameters with Clinical Test of Sensory Integration for Balance and to evaluate the discriminant validity of the Wii Fit center-of-pressure parameters for adults and the elderly for the assessment of postural sway. [Participants and Methods] This study used an observational cross-sectional correlational design. All 70 participants were required to complete a questionnaire for eligibility screening, followed by a center-of-pressure assessment using three Wii Fit balance activities (snowboard slalom, ski slalom, and balance bubble) and Clinical Test of Sensory Integration for Balance using a force platform. [Results] For center-of-pressure assessment, our results showed there was concurrent validity of Wii Fit ski slalom and balance bubble with Clinical Test of Sensory Integration for Balance conditions 6 and 4, respectively. Our results also demonstrated that the three Wii Fit balance activities selected in this study could be used to discriminate between adults and the elderly. [Conclusion] Our results suggest that Wii Fit is a viable and affordable alternative method for center-of-pressure assessment.Key words: Wii Fit, Centre of pressure, Validity |
