Abstract

Purpose:The purpose of this study is to analyze the effect of the arm extension pattern of proprioceptive exercise program on the muscle activity of the opposite lower extremity.
Methods: In this study, electromyogram MP150(Biopac system, USA) was applied to 20 healthy male subjects. Arm extensionadduction- internal rotation pattern was applied within initial, mid and end range in sling position and supine position for measurement. And the effect on the activity of rectus femoris and tibialis anterior muscle of the opposite lower extremity was compared and analyzed.
Results: The results of this study were summarized as follows: First, there was a statistically significant difference of the activity of the tibialis anterior muscle within the Initial range in sling position and supine position(P<0.05). Second, there was a statistically significant difference of the activity of the tibialis anterior muscle within the end range in sling position and supine position(P<0.05).
Conclusion: Rectus femoris and tibialis anterior muscles shows the higher activity in the supine position than in the sling position. Therefore, the supine position is more appropriate than the sling position to make irradiation on lower extremity muscle with the extension pattern.
