Traditionally, lateral epicondylitis causes characteristic pain in the lateral elbow region and is often associated with significant morbidity. It occurs most commonly in individuals between 40 and 50 years and equally affects both men and women. The dominant arm is involved in 75% of patients. While other etiologies have been proposed, including radial nerve entrapment, it is generally agreed that tennis elbow is the result of repetitive mechanical micro-trauma and overuse, but many cases have no biomechanical association, nor vocational or avocational correlation. This condition is often brought about by repeated flexion and extension of the wrist or by a direct injury to the epicondyle or elbow. However, most patients are unable to recall or to identify a precipitating event. The average duration of an episode of lateral epicondylitis is 6 to 24 months, and 10% to 30% of cases result in work absenteeism, leading to a high loss of productivity. Numerous treatment options have been described for lateral epicondylitis. Most cases are managed in primary care settings, and although there are more than forty possible treatments, there is still a lack of consensus about optimal therapeutic management. Moreover, most of these treatments lack sound scientific evidence.
