The rotator cuff is a group of 4 muscles that are responsible for stability of the shoulder. Unfortunately, rotator cuff injuries are very common, either from repetitive overuse or from trauma to the shoulder. These injuries can occur at any age, but are more prevalent later in life. We often think of athletes or heavy laborers as being the most commonly affected, but older adults can injure the rotator cuff when they fall or strain their shoulder, such as when walking a dog on a leash and the dog lurches. If left untreated, this injury can cause significant pain and severely hamper your ability to use your arm.
WHAT IS SHOULDER IMPINGEMENT?
Shoulder Impingement occurs as a result of chronic and repetitive compression of the rotator cuff tendons in the shoulder, causing pain and mobility issues. Individuals who perform repetitive or overhead arm movements, such as manual laborers (e.g., painters, drywall installers) or athletes who raise their arms repeatedly overhead (e.g., swimmers, tennis players, baseball pitchers) are most at risk for developing a Shoulder Impingement.
