Effect of Muscle Fatigue on the Upper Trapezius Muscle With and Without Myofascial Trigger Points in Students With Neck Pain: A Randomized Controlled Clinical Trial

Objectives: The purpose of this work was to explore cervical position sense and electromyographic (EMG) responses muscles during head repositioning movements in students with without upper trapezius muscle trigger points. Materials Methods: Forty-six right-handed men women subjects extremity disorders participated study. maximal voluntary contraction (MVC) measured three time before the fatigue test. A force gauge used measure while recording a monitor. Measurement initiated MVC after pain positioning were measured. When protocol accomplished, showed signs exhaustion; however, they not subjectively evaluated for fatigue. As aimed at assessing fatigue, level 80% induced. Results: These findings support argument that precision neck can be reduced by muscle. Fatigue impaired balance muscles. After removing vision resulted an increased center pressure excursions on platform. Motor control did change significantly Conclusions: had more significant effect kinematics healthy subjects, probably due fact altered motor volunteers implied these individuals completely able make up Significant changes identified following applied pre-determined myofascial points, but insignificant sham group.
