Tennis Elbow Defined
Tennis elbow, more formally known as lateral epicondylitis, is not an injury reserved exclusively for tennis players. In fact, tennis elbow commonly affects people in a number of occupations that involve repetitive gripping activities such as hammering, painting, or using a wrench or screwdriver. With repetitive gripping, the wrist will move into a position of relative extension and activate the muscles on the back of the forearm. Many of these muscles combine to form a single tendon which then attaches to the bony protrusion on the side of the elbow (the lateral epicondyle). Therefore, this tendon experiences a great deal of tension over a small area creating the perfect scenario for an overuse injury.
