The Role of the Rotator Cuff: Understanding Shoulder Stability

The rotator cuff is a group of muscles which provide stability to the shoulder joint. There are 4 small muscles which are grouped together to perform this function.

These muscles are called the supraspinatus, infraspinatus, teres minor and subscapularis.

These muscles attach the bone of your arm called the humerus, with the bone in your shoulder called the scapula, keeping the ball in the socket when completing tasks such a lifting, pushing, pressing and exercises involving the larger muscle groups around the shoulder.

As the name suggests, the main movements that the rotator cuff assists with is rotation and elevation enabling you to move your arm away from your body and over your head to perform daily tasks.

Because these muscles are so important for stability, they are repetitively used throughout the day. Sometimes this can lead to the rotator cuff tendon becoming aggravated, painful and potentially a tear.

When this is the case, physiotherapy can support with shoulder rehabilitation exercises which aim to restore range of movement, stability, strength and function.

If you think you have a rotator cuff injury or would benefit from support with exercises to strengthen this area, then contact Unique Physio to make an appointment with a member of the team.
