ABSTRACT
The repetitive1 or sustained movements, that are now intrinsic in work routines, are often direct cause of musculoskeletal injuries located in the shoulder. In the case of the violinists it should be added that these movements are forced, which represents an aggravating to the situation. The present work aims to study the behavior of the glenohumeral joint under different postures that represent the routine of a violinist and under RULA criteria (rapid upper limb assessment). A FEM analysis of the joint was developed by using ANSYS® [VERSION 17.1] software and as geometry of the joint a model generated in CATIA® [VERSION 5R21] ® that allowed linear and isotropic approximations of short and cyclic movements of the humerus. These affect the behavior of the muscles and tendons that make up the rotator cuff. The carried out analysis allowed to know the approximate behavior of the tissues under certain repetition cycles.
