You may have heard the term “rotator cuff” before. It is a common location for a shoulder injury. But what exactly is it? And why is it so easy to injure?
The rotator cuff consists of four muscles that surround the shoulder blade (scapula), and help to hold the arm bone (humerus) in the shoulder capsule. In other words, they help to stabilize the shoulder joint.
Each of the four muscles work in conjunction with one another to provide coordination of movement between the scapula and humerus when exercising, participating in sport, or doing something as simple as lifting an arm overhead. The shoulder joint sacrifices stability for mobility, as a result, a small change in muscle coordination can have dire consequences.
Common shoulder injuries include:
- Rotator cuff tendonitis
- Rotator cuff tears
- Labral tears
- Ligament strains and tears
Strengthen your rotator cuff to avoid injury
Many of these injuries can be avoided by keeping our rotator cuff flexible and strong. Try these three simple exercises each day to prevent shoulder injury:
- Shoulder stretch: Place arm up on the wall, lean forward into the doorway until a stretch is felt at the front and top of shoulder. Maintain the stretch for 30 seconds, repeat three times.
- Shoulder external rotation: Lay on your side with knees bent, head supported and arm on the side on a rolled towel. Rotate the arm at the shoulder without any other movement. Use a light weight, 3-5lbs. Do 3 sets of 10.
- T raises: Lie face down with your arms out, thumbs up and shoulders back and down. Raise your arms up as you squeeze your shoulder blades together. Lower your arms and repeat. Keep your thumbs up at all times. Perform two sets of 10 repetitions – holding 5 seconds each rep.
If you start to experience shoulder pain, book an appointment with one of our physiotherapists who can help you onto the path of recovery.
