Upper Trapezius Myofascial Trigger Point in Overhead Athletes After Upper Trapezius Muscle Fatigue

Plain-language summary

The healthy overhead athletes with and without upper trapezius myofascial trigger point will be asked to perform a scapular elevation task until the upper trapezius muscle fatigue. The first hypothesis is that the subjects with upper trapezius myofascial trigger point will show significant difference in scapular kinematics and muscles activities when compared to subjects without upper trapezius myofascial trigger point. Besides, the investigators suggest that subjects with/without upper trapezius myofascial trigger point will show significant difference in scapular kinematics and muscles activities after upper trapezius muscle fatigue, especially in subjects with upper trapezius myofascial trigger point.
