Variation in external rotation moment arms among subregions of supraspinatus, infraspinatus, and teres minor muscles

A rotator cuff tear causes morphologic changes in rotator cuff muscles and tendons and reduced shoulder strength. The mechanisms by which these changes affect joint strength are not understood. This study's purpose was to empirically determine rotation moment arms for subregions of supraspinatu...
