The Nintendo Wii Fit may provide an affordable alternative to traditional
biofeedback or virtual reality systems for retraining or improving motor function
in populations with impaired balance. The purpose of this study was to evaluate
postural control strategies healthy individuals use to play
Wii Fit videogames.
Sixteen young adults played 10 trials of Ski Slalom and Soccer Heading
respectively. Centre of pressure (COP) excursion and three-dimensional movement
data were acquired to determine variability in medial-lateral COP sway and
shoulder-pelvic movement. While there was no difference in medial-lateral COP
variability between games during trial 1, there was a significant difference
after 10 trials. COP sway increased (59-75 mm) for Soccer Heading while it
decreased (67-33 mm) for Ski Slalom from trial 1 to trial 10. During Ski Slalom
participants demonstrated decreased shoulder and pelvic movement combined with
increased pelvic-shoulder coupling. Conversely, participants demonstrated greater
initial shoulder tilt when playing Soccer Heading, with no reduction in pelvic
rotation and tilt. 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 Heading.
