Joint contact force comparisons for the axilla wash for rotator cuff tear (gray) and control (black) participants. (A) Mean (SD) peak resultant joint contact force was significantly smaller for the rotator cuff tear group (P=0.0456). (B) Coronal and (C) superior views of the joint do not exhibit significant differences between the magnitude or direction of the planar components of the resultant force vector for the two groups. Shaded cones represent 1 SD of the mean position of the resultant vector; dashed lines represent 1 SD of the mean magnitude of the resultant force vector. (D) Anterior-posterior and superior-inferior components of the peak joint contact force are overlayed on an oval representing the glenoid fossa, where the superior component of the peak resultant force for one subject with a rotator cuff tear extended beyond the boundary of the glenoid fossa.
