There are a few key differences between a rotator cuff strain and tear. A rotator cuff strain is a stretching or micro-tearing of the tendons and muscles surrounding the shoulder joint while a tear is a complete or partial tearing of one or more of the tendons in the shoulder.
For starters, both have similar symptoms like pain, swelling, and stiffness. With a tear, the arm can barely move overhead. Tendinopathy tends to happen over months, even years, of overuse. Tears, however, are sharp pains that generally occur after a sports collision or accident.
The pain associated with a rotator cuff injury may: Be described as a dull ache deep in the shoulder. Disturb sleep. Make it difficult to comb your hair or reach behind your back.
The drop arm test is used to assess for full thickness rotator cuff tears, particularly of the supraspinatus. This can be useful when diagnosing sub-acromial pain syndrome (shoulder impingment) or to differentiate between shoulder and rotator cuff pathologies.
Your doctor uses imaging tests to help diagnose a rotator cuff injury. An X-ray helps to rule out bone spurs or osteoarthritis as a cause of your symptoms. An MRI scan enables your doctor to see the soft tissue in the shoulder and determine if you have a rotator cuff tear and whether it is partial or full thickness.
How long does it take to recover from a rotator cuff injury? The minimum recovery time for rotator cuff tendonitis is generally two to four weeks. Left untreated, rotator cuff tendonitis can worsen and may lead to a partial or complete rotator cuff tear.
Usually, mild rotator cuff tears or sprains will heal within four weeks. In other severe cases, the recovery might take 4 to 6 months or even longer based on several factors such as the severity of the tear, age, and other health complications.
The minimum time for recovery from rotator cuff tendonitis or a small tear is generally two to four weeks, and stubborn cases can take several months. Early on, the aim is to reduce swelling and inflammation of the tendons and relieve compression in the subacromial space.
The most common symptoms of a rotator cuff tear include: Pain at rest and at night, particularly if lying on the affected shoulder. Pain when lifting and lowering your arm or with specific movements. Weakness when lifting or rotating your arm.
Rotator cuff tendon tears often cause pain at night. The pain may even wake you. During the day, the pain is more tolerable, and usually only hurts with certain movements, such as overhead or reaching toward the back. Over time, the symptoms become much worse and are not relieved by medicines, rest, or exercise.
But any inflammation or partial or full tear can make performing daily activities very painful. Symptoms of a rotator cuff injury may include: Pain or tenderness when reaching overhead. Pain or tenderness when the arm is at rest.
A shoulder sprain occurs when the ligaments overstretch or tear, while a shoulder strain is when some of the fibers in the shoulder muscles or tendons overstretch or tear. These injuries can limit your ability to move and lift your arms and can cause acute or chronic pain.
Even though most tears cannot heal on their own, you can often achieve good function without surgery. If, however, you are active or use your arm for overhead work or sports, surgery is most often recommended because many tears will not heal without surgery.
Moist heat, such as a hot bath, shower, or a heat pack, can help loosen up your shoulder when you feel pain in your shoulder. An ice pack applied to the shoulder 20 minutes at a time, 3 to 4 times a day, may also help cut down the swelling when you are in pain.
Without any treatment—either rest and rehabilitation or surgery—rotator cuff disorders may get worse. Over time, you may have more pain. You may lose range of motion and strength in your shoulder, making it harder to do your daily activities.
Delaying treatment of a torn rotator cuff can increase the risk of the shoulder sustaining even more damage because the tendons and muscles cannot heal properly. The overused muscles will start fraying, and additional tears can develop.
Movement restriction. It will be difficult to move your arm and shoulder normally if the rotator cuff is torn. Simple tasks like brushing your hair, dressing, and cooking will be excruciatingly painful. You may find it challenging to carry even small objects due to the lack of range of motion.
Patients are often advised to wear a sling or brace for the first 4–6 weeks after rotator cuff repair surgery to prevent them from performing any physical activities involving the affected shoulder (3).
Patients still have the ability to raise their arm, and they can still do day-to-day things, but they tend to have some pain. So, being able to use the arm and move it and raise it above your head does not necessarily mean that the rotator cuff is intact.
In this test you begin by placing the injured arm behind your back, with the back of your hand resting on you lower back. Now try to raise your arm off of your back.. If you feel pain or weakness when trying to lift your hand off of your back, that is a sign that there could possibly be rotator cuff injury involved.
The empty can test is a clinical test used to test the integrity of the supraspinatus tendon. In this test, the patient is tested at 90° elevation in the scapular plane and full internal rotation (empty can). The patient resists downward pressure exerted by the examiner at the patients elbow or wrist.
Grade 1 strains: Injuries in the rotator cuff occur when the fibers of the muscles or tendons are stretched beyond their capacity. Grade 2 strains: Injuries in the rotator cuff occur when the fibers of the muscles or tendons are strained too far and partially tear.
