The pelvic girdle and the shoulder girdle are not alike in their functions related to stabilization and motion of the extremities. In the shoulder girdle the scapula and clavicle work together as unit. The scapula’s primary support is muscles with only one attachment to the axial skeleton, at the manubrium. The shoulder girdle is dependent on muscular function and its ability to adjust to the underlying rib cage. In its normal function it is not a weight-bearing structure. The scapula patterns are activated (whether for motion or stabilization) within the upper extremity patterns and all the upper extremity patterns and scapula motions integrate together.
