The shoulder is the most mobile joint in the body, with only one boney attachment to the axial skeleton. As a result the soft tissue structures which form a “complex” rely on a delicate coordination to maintain the stability of the glenohumeral joint. Shoulder pain or injury can come on spontaneously or as a result of chronic overuse and (poor) postural contributions. Pain can come from any one tissue or a combination of many structures in the shoulder complex, which can often make accurate assessment challenging. Skilled evaluation is essential to determine an effective course of treatment to return you to your life without risk of re-injury.
