Rotator Cuff Injury and Rotator Cuff Exercises
Learn treatment and prevention tips for rotator cuff injury, plus effective rotator cuff muscle stretches and exercises.
Have you ever been working out at the gym, pushing a heavy weight and heard a popping sound in your shoulder. Or what about skiing down the slopes and landing shoulder first in the snow. Or maybe just having a friendly game of tennis, when all of a sudden there’s a sharp pain in your shoulder.
These are all signs of the same thing; a rotator cuff injury. Whether you want to call it a rotator cuff tear or strain, or shoulder tendinitis, it’s really all the same: A tear, strain or inflammation in one or more of the rotator cuff muscles and/or tendons.
Please Note: Frozen shoulder is a slightly different condition affecting the shoulder joint where the surrounding capsule becomes inflamed.
Anatomy of the Shoulder Joint
The shoulder joint is a truly remarkable creation. It’s quite a complex formation of bones, muscles and tendons and provides a great range of motion for your arm. The only downside to this extensive range of motion is a lack of stability, which can make the shoulder joint vulnerable to injury.
Lets have a quick look at the shoulder joint in a little more detail. The shoulder is made up of three bones, and the tendons of four muscles. (Remember, tendons attach muscle to bone.) The bones are called the “Scapula,” the “Humerus” and the “Clavicle.” Or, in layman’s terms, the shoulder blade, the upper arm bone and the collarbone, respectively.
The four muscles which make up the shoulder joint are called, the “Supraspinatus,” the “Infraspinatus,” the “Teres Minor” and the “Subscapularis.” It is the tendons of these muscles, which connect to the bones, that help to move your arm.
In the picture to the right, three of the four muscles are visible, the supraspinatus, the infraspinatus and the teres minor. These are the muscles which are viewed from the rear, or posterior. The subscapularis is not visible because it can only be viewed from the front, or anterior and this particular view only shows the muscles from the rear, as if looking at someone’s back. Anyway, enough of the technical stuff.
What Causes Rotator Cuff Injury?
There are two major causes of most shoulder injuries. The first being degeneration, or general wear and tear. Unfortunately, the shoulder is a tendinous area that receives very little blood supply. The tendons of the rotator cuff muscles receive very little oxygen and nutrients from blood supply, and as a result are especially vulnerable to degeneration with aging. This is why shoulder problems in the elderly are common. This lack of blood supply is also the reason why a shoulder injury can take quite a lot of time to heal.
The second cause of most shoulder injuries is due to excessive force, or simply putting too much strain on the tendons of the shoulder muscles. This usually occurs when you try to lift something that is too heavy or when a force is applied to the arm while it’s in an unusual or awkward position.
Symptom of Rotator Cuff Injury
There are two common symptoms of a shoulder injury, pain and weakness. Pain is not always felt when a shoulder injury occurs, however most people who do feel pain, report that it’s a very vague pain which can be hard to pinpoint.
Weakness, on the other hand, seems to be the most reliable symptom of a shoulder injury. Common complaints include an inability to raise your arm above your head or to extend your arm directly to the side or in front. In most cases, the larger the tear or damage to the tendons, the harder it is to move your arm and the injured area.
Rotator Cuff Injury Treatment
The earlier a rotator cuff injury is treated, the better. The first 48 to 72 hours are crucial to a complete and speedy recovery.
The first and most important course of action is the R.I.C.E.R. regimen. Rest, Ice, Compression, Elevation and Referral. Take a look at our comprehensive R.I.C.E.R. regimen article for a more detailed explanation of how (and why) to use the R.I.C.E.R. regimen.
After the initial injury has been treated with the R.I.C.E.R. regimen, (for at least 48 to 72 hours) it’s time to move onto the next stage of treatment. As mentioned before, the shoulder joint receives very little blood supply. So, what can you do to increase blood flow, and oxygen and nutrients to the injured area?
Firstly, heat! Heat is extremely good for increasing blood flow to a particular area. Heat lamps are the most effective way to increase blood flow, while heat based creams are probably a distant second choice.
Secondly, massage! Massage is one of the best ways to increase blood flow to an injured area, and of course the oxygen and nutrients that go with it. The other benefit of massage is that it helps to reduce the amount of scar tissue, which is associated with all muscle and tendon, strains and tears.
Lastly, don’t stop moving. Some doctors will often tell patients to keep the injured area still, and this is not always the best advice. Gentle movement will help to keep the blood flowing to the injured area. Of course, if pain is present, limit the amount of moving you do, but don’t stop moving all together.
Rotator Cuff Injury Prevention
Mark my words, “Prevention is much better than Cure.” Anything you can do to prevent an injury from occurring is worth it. The prevention of shoulder injuries comes down to the conditioning of the shoulder muscles and tendons, which ultimately involves both stretching and strengthening of the shoulder joint. Watch instructional videos of shoulder stretching exercises.
Also, don’t forget the common injury prevention techniques like, warming up properly and using a bit of old-fashioned common-sense. However, for the most part, stretching and strengthening are going to be your best defense against shoulder injury. Even if you don’t have a shoulder problem now, the following stretching and strengthening exercises could save you from a major trauma in the future.
Firstly, below you’ll find two good stretches for the shoulder area. The first is quite a basic stretch, while the second is a more advanced stretch, specifically for the rotator cuff muscles and tendons. Please be careful, if you haven’t been stretching your shoulder joint, the second stretch will put quite a lot of stress on the rotator cuff tendons. Warm-up first, then gently and slowly is the best way to proceed.
In the stretch to the left, simply stand upright and clasp your hands behind your back. Keep your arms straight and slowly lift your hands upwards. Hold this stretch for about 15 to 20 seconds, then repeat it 3 to 4 times.
In this stretch, stand with your arm out and your forearm pointing upwards at 90 degrees. Place a broom stick or pole in your hand and let it fall behind your elbow. With your other hand, pull the bottom of the stick forward. Be especially careful with this stretch, it will put a large strain on the rotator cuff muscles and tendons. As above hold this stretch for about 15 to 20 seconds, then repeat it 3 to 4 times.
Secondly, strengthening and conditioning the muscles of the upper back, chest and shoulders will also help to prevent rotator cuff injury. There are a number of specific strengthening exercises you can do for these muscles, including dumbbell exercises and Thera-Band exercises. For a comprehensive, step-by-step treatment program, take a look at our 7 Step Rotator Cuff Treatment System.
The recommendations on this page are a good starting point, but if you’ve injured your rotator cuff or you’re trying to recovery after shoulder surgery, take a look at our 7 Step Rotator Cuff Treatment System.
The 7 Step System is a systematic, step-by-step, proven method of reducing your pain, fixing your rotator cuff injury properly, and then making your shoulder so strong and stable you’ll never have to worry about shoulder pain again.
