Abstract:
The shoulder is one of the most complicated and heavily worked joints in the body. It also has the greatest range of motion of any joint! As such, it is no surprise that it is also highly vulnerable to injury. The shoulder’s rotator cuff is an important series of four muscle groups and their tendons that connect the shoulder blade to the upper arm bone, or humerus. When the “cuff” is injured, it can become difficult, and even impossible, for a person to lift, throw, stretch or do any of the other chores assigned to the shoulder—even getting dressed can be incredibly difficult.
