What is the Rotator Cuff?

When someone is describing their shoulder injury, you will most likely hear the words 'rotator cuff’ at some point. Perhaps you read some information about your shoulder pain and came across these words. But what actually is it and what does it do? ​

In summary, the rotator cuff is the collective name for 4 specific muscles of the shoulder. These muscles are: 

• Supraspinatus 
  

• Infraspinatus 
  
• Teres minor 
  
• Subscapularis ​
  

What do they do?

The rotator cuff muscles are involved in most movements produced at the shoulder, primarily rotation as the name implies. As a group, the rotator cuff muscles are responsible for providing stabilisation to the shoulder during movement. As the shoulder moves, the rotator cuff muscles work to hold the head of the humerus within the glenoid (shoulder socket) to allow smooth movement through the entire range of motion. ​

Why is it important?

An injury to the rotator cuff can result in pain and loss of function at the shoulder, as all muscles must work together to produce stability and normal movement. Due to the relatively small size and strength of the rotator cuff, injuries are common. ​

Did you know? 
Based on research, 1 in 5 people are currently living with a rotator cuff tear. The majority of these tears are minor in nature and less than half are symptomatic (painful). Like any muscle, the rotator cuff should be trained to maintain strength and prevent injury. Find out if your shoulder pain is caused by the rotator cuff here at Physio Labs and let us guide you on the road to recovery.  ​
