Abstract

Object: Exercise induced fatigue is related to position sense of joint although some controversy remains. It has been hypothesized that proprioceptive information plays an important role in joint stabilization and that muscle fatigue may alter proprioceptive ability. The purposes of this study were to examine the effect on the accuracy of reproducing the shoulder angles before shoulder girdle exercise and after a fatiguing isokinetic shoulder girdle exercise.
Methods: The subjects were consisted of 45 healthy adults and females) who had no problems on their musculoskeletal system. Before the exercise induced fatigue, the proprioception was measured by three-dimensional motion analysis. Using the isokinetic device at 120˚/sec of velocity of angle 25 times shoulder flexion/extension exercise caused muscle fatigue. Using the three-dimensional motion analysis, the proprioception was remeasured. The method of proprioception measure compared to excursion angles on the accuracy of reproducing between passive motion and active motion. After that we compared the result of measurement of before and after.
Results: Results of this study showed that there was a significant difference of the shoulder joint positioning sense between before and after fatigue following the exercise in abduction-adduction and internal rotation-external rotation. But there was no significant difference of the shoulder joint positioning sense between before and after fatigue following the exercise in flexion-extension.
Conclusion: Shoulder proprioception in active repositioning in abduction-adduction and external rotation-internal rotation was major affected by muscle mechanoreceptors in the presence of muscle fatigue.
