dc.description.abstract-translatedMusculoskeletal models of the shoulder complex yield the possibility to aid in clinically relevant research questions e.g. tears of the supraspinatus and the resulting mechanical impact during abduction of the humerus. One of the major contributors to this motion is the deltoid muscle group, where an accurate modelling of the lines of action is indispensable. The aim of this work is to utilize a torus obstacle wrapping approach for the deltoids of an existing shoulder model and assess their feasibility during humeral abduction. The shoulder model from the AnyBodyTM modelling system is employed as platform for utilizing the torus obstacles for the deltoid wrapping. The size of the tori is based on an MRI approach and several kinematic couplings are implemented to determine the trajectories of the tori during abduction. For the validation, the moment arms of the virtual muscle elements and the resultant glenohumeral joint reaction force are compared to reference data from literature during abduction of the humerus in the range 20-120°. The root mean square error for the anterior, lateral and posterior part between the simulated muscle elements and reference data from literature is at 3.9, 1.7 and 5.8 mm, respectively. The largest deviation occurs on the outer elements of the muscle groups with 12.6, 10.4 and 20.5 mm. The glenohumeral joint reaction force is in accordance with in-vivo measured data from literature in terms of progression and amplitude, where the three element Hill model possesses a better fit. During the abduction, the muscle elements show no overlapping and are in continuous contact with the torus obstacles. The torus obstacle approach as a wrapping method for the deltoid muscles has the advantage of providing a guided muscle pathing by simultaneously approximating the curvature of the deltoid. The results from the comparison of the simulated moment arms and the resultant glenohumeral joint reaction force are in accordance to literature in the range between 20-120° of abduction. These results indicate that the torus approach is a suitable solution for representing the lines of action of the deltoid muscle group. However, for a kinematic scheme which also enables an accurate motion of the tori for humeral flexion more research is neededen
