An overuse injury is caused because the burden to which the elbow is exposed is greater than the level of load the elbow can cope with. As a consequence of the overburdening, tension and /or stretching the affected muscles can cause pain.
An overuse injury around the elbow often occurs following high-frequency repetition of the same (incorrect) movement. This occurs particularly in sports like tennis. The attachment of the muscles that tense the wrist become overburdened. These muscles are attached close to the elbow.
