Scaling and kinematics optimisation of the scapula and thorax in upper limb musculoskeletal models.
Bottom Line: These rely on thorax scaling to effectively define the scapula's path but do not consider the area underneath the scapula in scaling, and assume a fixed conoid ligament length.The scapula and clavicle kinematics are optimised with the constraint that the scapula medial border does not penetrate the thorax.This method is simulated in the UK National Shoulder Model and compared to four other methods, including the standard technique, during three pull-up techniques (n=11).

Mentions: The effect of different optimisation parameters are compared through mean differences to measured rotations and 95% confidence intervals (C.I.) of those optimised rotations (Figs. 2 and 3). The PCC optimisation method is closest to the measured values – with significantly smaller errors in many cases. All the other methods fall outside the scapulothoracic measurement errors (Fig. 2).
