Precision of shoulder anatomical landmark calibration by two approaches: A CAST-like protocol and a new anatomical palpator method

Shoulder motion during tennis serve: dynamic and radiological evaluation based on motion capture and magnetic resonance imaging

“…To address these two issues, we used a previously developed and validated biomechanical model based on a patientspecific kinematic chain consisting of four rigid bodies (thorax, clavicle, scapula and humerus) using the tennis player's shoulder 3D models reconstructed from their MRI data. To register internal anatomical structures to the marker cluster frames, a calibration was performed based on a standard CAST (calibrated anatomical system technique) protocol [31]. The optimal pose of the kinematic chain was then obtained using a global optimization algorithm (to minimize STA error globally [29]) with loose constraints on joint translations.…”

Rotation sequence is an important factor in shoulder kinematics. Application to the elite players’ flat serves

“…The second rotation sequence, Z t -X f ' -Y h '' (ZXY), corresponded to the general ISB recommended rotation sequence for most joints (Grood and Suntay, 1983;Wu, 2002). The third rotation sequence, X t -Z f ' -Y h '' (XZY), was used for shoulder in previous studies (Rundquist et al, 2003;Salvia 2009;Senk and Ch eze, 2006). The indices t, h and f represent the axis embedded on the thorax SCS, the humerus SCS and a floating axis, respectively.…”

“…Indeed, the large range of motion in the shoulder joint does not allow for a unique standard for 3D kinematic analysis. Shoulder motion is an intricate interaction between four bodies (Fayad et al, 2008;Hill et al, 2008;Rau et al, 2000;Salvia, 2009;Senk and Ch eze, 2006): the thorax, scapula, humerus and clavicle. It appears that the shoulder motions can be divided in three groups: scapular motion relative to the thorax (scapulo-thoracic joint), humeral motion relative to the scapula (gleno-humeral joint) or humeral motion relative to the thorax (shoulder complex).…”
