How important is shoulder mobility?

The biomechanics of the shoulder girdle consist of the clavicle, scapula and the humerus. There are many different ligament structures that help this joint perform correctly. The primary function of the shoulder girdle is to provide stability and range of movement throughout the shoulder. Scapula dyskinesia does not always affect the range of movement within the joint and wouldn’t necessarily adversely affect the ligaments and tendons. There are many muscles that help to stabilise the humerus in the glenohumeral joint – subscapularis (which is known for medial rotation of the humerus), supraspinatus (which initiates abduction up to 30 degrees), and the infraspinatus and teres minor (which are both lateral rotators of the humerus). These muscles are known as the rotator cuff muscles and they all help to stabilise the head of the humerus into the glenohumeral joint (Carbone et al., 2017).

Shoulder mobility is important for everyone because we use our shoulders in day-to-day activities and help when playing overhead sports. It is important from a strengthening side and stretching perspective because of the large range of movement that can be performed at this joint.

Today I have made a video with a few exercises that can help improve shoulder mobility and increase the range of movement within the shoulder joint. 

Let’s keep those shoulders happy!
