Body-movement values were measured with the Mac Reflex motion-analysis system.
Subjects stood barefoot.
Main Outcome Measures:
ANOVAs were used to explain the body movements. The location of measurement, presence or absence of vision, and subjects’ age and gender were used as explanatory variables.
With eyes closed, all measured body parts had significantly higher maximal velocity and acceleration values than with eyes open. Age seemed to affect the acceleration values.
Visual information was found to significantly influence movement values. Exercises should be done under various conditions to improve standing balance abilities.
