The rotator cuff is theorized to contribute to drive {couples} required to supply glenohumeral kinematics. Impairment in these drive {couples} would theoretically lead to impaired ball-and-socket kinematics. Although much less steadily used than conventional kinematic descriptors (e.g., Euler angles, joint translations), helical axes are succesful of figuring out alterations in ball-and-socket kinematics by quantifying the […]
