Abstract: The Nintendo Wii Fit may provide an affordable alternative to traditional biofeedback systems for retraining motor function in populations with impaired balance. The purpose of this study was to evaluate postural control strategies used by healthy individuals before testing its application in a rehabilitation setting. Sixteen young adults played 10 trials of Ski Slalom and Soccer Heading respectively. Centre of Pressure excursion (COP) and 3D movement data were used to establish variability in medial-lateral sway (COP) and shoulder-pelvic movement. While there was no difference in medial-lateral COP variability between games after trial one, there was a significant difference after ten trials. COP sway increased (59 to 75mm) for Soccer Heading while it decreased (67 to 33mm) for Ski Slalom. For skiing participants demonstrated decreased shoulder and pelvic movement combined with increased pelvic-shoulder coupling. Conversely, participants demonstrated greater initial shoulder tilt when playing soccer with no reduction in pelvic rotation and tilt. Therefore, participants decreased pelvic and trunk movements when skiing, suggesting a greater contribution of lower extremity control while they primarily used a trunk strategy to play soccer. Further studies should assess if these learned strategies are retained and if improved game performance correlates with improvement on standardized balance measures.
