Model for force and moment prediction of shoulder external rotation muscles in the transverse plane. Estimate the shoulder muscles forces and understand how much each muscle the moment production during joint movement is indispensable for the knowledge of the human movement, as well as, for the rehabilitation planning of patients with shoulder dysfunction.
For this reason, the goal of the present study is to estimate the muscle force and to analyze the contribution of the following muscles: Infraspinatus, Teres Minor, Supraspinatus, Deltoideus Posterior and Deltoideus Medialis during dynamic external rotation of the shoulder in the transverse plane.
The muscles Supraspinatus, Deltoideus Posterior and Deltoideus Medialis presented low magnitudes for external rotation moment and force. These results suggested Infraspitatus and Teres Minor muscles are preferentially recruited during external rotation of the shoulder.
