[EN]The majority of musculoskeletal injuries located in the shoulder are often due to repetitive or sustained movements that occur in
work routines in different areas. In the case of musicians, such as violinists, who have long and daily training routines, the
repetitive movements they performare forced and sometimes the postures are not natural. Therefore, this article aims to study and
simulate the dynamic behavior of the glenohumeral joint under repetitive conditions that represent the different postures assumed
by a violinist during his daily training. For this purpose, the criteria provided by the RULA (rapid upper limb assessment) method
have been used. Subsequently, by using as a reference geometry that of the articulation under study generated and modeled in
CATIA®[VERSIÓN 5R21], a FEM analysis has been proposed with the software ANSYS®[VERSIÓN 17.1] simulating the
short and cyclic movements of the Humerus of the violinists. With the analysis carried out, thanks to linear and isotropic
approximations of the joint, it has been possible to know the approximate dynamic behavior of tissues, muscles and tendons,
and the response of the joint in terms of fatigue.
