The aims of this study are to investigate the effects of scapular muscle fatigue on scapular joint position sense and neuromuscular performance (scapular muscle strength, the kinematics data and muscle activity of shoulder during scaption (arm elevation in the scapular plane)). The investigators hypothesize that scapular muscle fatigue would increase scapular reposition error and affect neuromuscular performance of the scapular during scaption.

| FG000 | Fatigued Group | Subjects held in a modify pushup plus position. Like an all four position, subjects hold with right arm with elbow flexion and full shoulder protraction. Male subjects had to hold three minutes for ten repetitions, and female subjects were two minutes for five repetitions. There was thirty second rest between repetitions. The end of fatigue task was: subjects finished all the repetition, or could not do one more repetition. Female subjects could do more than five repetitions if they felt ok, and the maximum repetitions were ten. The muscle activation of upper trapezius, lower trapezius, and serratus would record for analysis of median frequency. As long as finished fatigue task, the post measurements would start. |
