Physical Therapist's Guide to Rotator Cuff Tear
The "rotator cuff" is a group of 4 muscles that are responsible for keeping the shoulder joint stable. Unfortunately, injuries to the rotator cuff are very common, either from injury or with repeated overuse of the shoulder. Injuries to the rotator cuff can vary as a person ages. Rotator cuff tears are more common later in life, but they also can occur in younger people. Athletes and heavy laborers are commonly affected; older adults also can injure the rotator cuff when they fall or strain the shoulder, such as when walking a dog that pulls on the leash. When left untreated, this injury can cause severe pain and a decrease in the ability to use the arm.
