Previous clinical studies have reported associations between glenoid inclination (GI), the acromion index (AI), and the critical shoulder angle (CSA) on the one hand and the occurrence of glenohumeral osteoarthritis and supraspinatus tendon tears on the ot ...

The synthesis of shoulder kinematics, either for simulation in a model or imitation in a robot, is a challenging task because of the contact between shoulder blade and ribcage. As the shoulder moves, the shoulder blade glides over the ribcage. In kinematic ...

Osteoarthritis and rotator cuff tears are two common and wide spread shoulder diseases leading to significant restrictions in the daily life of the affected. The pathogenesis is not fully understood yet. A chronic process triggered by multiple causes is as ...

A clear and rigorous definition of muscle moment-arms in the context of musculoskeletal systems modelling is presented, using classical mechanics and screw theory. The definition provides an alternative to the tendon excursion method, which can lead to inc ...

Active Stability of Glenohumeral Joint Diminishes during the End-range Motions

Dominique Pioletti, Alexandre Terrier, Alain Farron, Philippe Müllhaupt, Christoph Anselm Engelhardt, David Ingram, Ehsan Sarshari

The lack of congruence between the involved articular surfaces causes the inherent instability of the glenohumeral joint. This joint is therefore the most commonly dislocated joint in the human body. Anterior instability accounts for over 90% of the should ...

The estimation of muscle forces in musculoskeletal shoulder models is still controversial. Two different methods are widely used to solve the indeterminacy of the system: electromyography (EMG)-based methods and stress-based methods. The goal of this work ...

Partial-thickness tears of the supraspinatus tendon frequently occur at its insertion on the greater tubercule of the humerus, causing pain and reduced strength and range of motion. The goal of this work was to quantify the loss of loading capacity due to ...

Modelling the shoulder's musculature is challenging given its mechanical and geometric complexity. The use of the ideal fibre model to represent a muscle's line of action cannot always faithfully represent the mechanical effect of each muscle, leading to c ...

The kinematics of the anatomical shoulder are analysed and modelled as a parallel mechanism similar to a Stewart platform. A new method is proposed to describe the shoulder kinematics with minimal coordinates and solve the indeterminacy. The minimal coordi ...

Stability of the shoulder, more precisely the glenohumeral joint, can only be achieved in case of healthy and well coordinated muscular activity in the upper limb. Degenerative deseases like osteoarthritis, muscle deficiencies or injuries can lead to insta ...
