![]() ![]() Muscle Tightness / Weakness / Imbalance:Ī balance of the muscles that stabilize the scapula (shoulder blade) is vital to proper biomechanics at the glenohumeral joint and limits the risk of shoulder impingement, degenerative joint disease, and rotator cuff injury.Ĭore strength and neutral stabilization of the rib cage and spine are also critical. The UCSP brings with it a very predictable set of muscle imbalances that we will discuss further. This common posture that is further exacerbated by hours of working slumped over a computer or cell phone is referred to as the upper cross strain pattern (UCSP). Because many of the muscles that attach to the shoulder girdle and/or arm bone originate and are anchored to the rib cage and spine, the position or good posture is critical. For all the muscles to work effectively to meet the many demands we place on our shoulder joints we must be working from a neutral rib cage and spine. ![]() Our shoulder girdle sits, virtually floats, in a sea of muscles atop our rib cage. Feel tension, pinching, and/or discomfort?.Did you experience restricted motion in your shoulder?.Try to raise your arm up over your head.Maintain your rib cage and spine position.Why is posture so important to the health and function of our shoulders? I think a demonstration is the easiest way to answer this. ![]() ![]() In addition to the sports, occupations, and recreational activities that create repetitive strain by using our arms above our heads, what else makes us susceptible to shoulder impingement? Poor Posture Overuse is a common cause of impingement, but rarely is it overuse alone that creates a long-term problem. So, let’s dive a bit deeper into the causes of shoulder impingement syndrome. Occupations at risk for secondary shoulder impingement syndrome are those who work with their arms up over their head or out to the side for extended periods of time like painters, construction workers, window washers, and hairdressers. ![]()
