Evaluation of Shoulder Stability During Forceful Arm Exertions

摘要: Shoulder musculoskeletal disorders (MSDs) are a major cause of morbidity and pain in the modern working population. Epidemiological literature suggests that forceful arm exertions pose an increased risk for shoulder MSD development. The majority MSDs involve glenohumeral joint. joint is characteristically unstable stabilized by concavity compression mechanism. In this study biomechanical model complex was used to examine Mechanical loading during analyzed quantify angular position resultant muscle force vector 3D space. vectors were almost always directed anteriorly, medially, inferiorly, independent magnitude direction external application. knowledge gained could possibly be strain imposed on muscles exertions.
