The dynamics of the upper extremity can be modeled as the motion of an open kinematic chain of rigid links, attached relatively loosely to the trunk. The upper extremity or upper limb is a complex mechanism which includes many bones, joints, and soft tissues allowing various movements in space. The shoulder is one of the most complex musculoskeletal units not only in the upper limb but also in the entire human body. Codman [7] understood the complex and dependent relationships of the structures of the shoulder when he coined the term “scapulohumeral rhythm” to describe the coordinated motion. The purpose of the paper is to present a simple mathematical model of the scapulohumeral rhythm using the apparatus of the Generalized Nets Theory [1, 2]. The presented model is a part of a series of generalized net models of the upper limb developed by the authors (see [22, 23]).
