The shoulder is an extremely mobile joint, allowing people to reach and move in many directions. However the mobility does predispose the shoulder to injury which can make even the simplest daily activities painful.
How Does the Shoulder Work?
The shoulder consists of two primary joints, the glenohumeral joint and the acromioclavicular joint. The glenohumeral joint is the connection of the humerus (arm bone) with the scapula (shoulder blade). The acromioclavicular joint is the connection of the clavicle (collar bone) and the scapula (shoulder blade). The glenohumeral joint is a complex ball and socket joint that allows for movement in several planes of motion. There are many ligaments that help support the shoulder, and many muscular attachments, particularly the "rotator cuff", which aid in support and movement of the shoulder.
Causes of Shoulder Pain
The shoulder can be injured suddenly in a traumatic incident or over a period of time by performing repetitive movements or positions. Additionally, pain can occur in the shoulder from diseases or degenerative conditions. One of the most prevalent causes of pain in the shoulder is rotator cuff pathology, which involves the primary dynamic stabilizing muscles of the shoulder. Other soft tissue or nerves that supply motor and sensory innervation to the shoulder can also produce pain in specific conditions.
The Importance of Exercise Therapy
The fundamental principle in shoulder rehabilitation is stability during movement. The framework for this is to normalize the shoulder anatomy as well regains the correct biomechanics. Through strengthening and stretching of specific muscles, shoulder stabilization and progressive correction of the biomechanics can occur. Having experienced a shoulder injury, the majority of patients do not have the knowledge to rehabilitate themselves safely. It is emphasized that rehabilitation techniques of the shoulder need to be individualized, providing a complete program tailored to your need and goals.
