Abstract
The purpose of this study was to investigate the effects of visual information and different elevations of medially wedged insoles on the proprioceptive sense of the knee joint. The subjects of this study were 16 able-bodied men who were not athletic. An electrogoniometer was used to determine the error value between calculated 50% of full flexion (target position) and performed 50% of full flexion in a standing position with the upper extremities crossed. Tests were randomly performed in 2×4 conditions. Visual variations included open eyes vs. closed eyes, while the elevation was adjusted through the use (or lack thereof) of medially wedged insoles of 10 ㎜, 14 ㎜, and 18 ㎜. The average error value in each condition was statistically analyzed. The findings of this study revealed as follows: 1) The average error value was significantly higher with the subjects' eyes open than with their eyes closed (p＜.05). 2) The averaged error value was also significantly higher when the subjects were elevated 18 ㎜ than with no elevation at all (p＜.05). The findings of this study should be considered in lower extremity rehabilitation programs when medially wedged insoles used.
