Primary aim of the project is to determine the effect of different shoulder positions on gripping capability of hand and electro physiologic activityof upper extremity muscles. 23 case report data which have ages ranging between 18 and 30 are analysed. Depending on the shoulder flexion, hand gripping capability decreased explicitly. Suggested to analyse together with the fact that at levels higher than shoulders, despite maximum muscular activitythe hand gripping capability decreased explicitly is interpreted so that when the arm is raised the extremity exerts higher efforts for stabilizing the arm rather than ripping function. According to our results, as the shoulder flexion increases, muscular activity and depending on this the muscular exhaustion also increases where as the functional quality of hand decreases. The case is both a risk factor for an occupational disease and a situation that decreases skillful functioning of hands. For the next researches, advantages of exhaustion reducing apparatus and ergonomic systems, which can be used during works requiring over shoulder movements, are EMG results.trinfo:eu-repo/semantics/closedAccessErgonomyelectromyographymusculo skeletal disorderoverhead worksignal processingConference ObjectN/AWOS:000380505200091N/A
