A thorough assessment of the shoulder must look at the posture and dynamic mobility of both the shoulder and scapula. More importantly, we need to assess the interaction between the shoulder and scapula and not look at the two in isolation.
Assessing Shoulder and Scapular Dynamic Mobility
Altered scapular dynamic movement can be influenced by many things, so a thorough assessment is needed. Here is a clip from my brand new educational program with Eric Cressey, Functional Stability Training for the Upper Body. This is part of a lab demonstration of Eric Cressey and I assessing overhead arm elevation and the quality of shoulder and scapular mobility. In this clip you can clearly see a side-to-side difference and we discuss some of the potential implications:
