Lateral epicondylitis (commonly referred to as “tennis elbow”) is a disorder characterized by pain at or near the lateral epicondyle of the humerus. The pain may be localized to this region, may radiate down the extensor muscle group of the forearm, and occasionally may radiate proximally to the upper arm (Vaquero‐Picado, Barco, & Antuña, 2017). This pain can be triggered or exacerbated by contraction of the common extensor mass in response to a variety of activities (Ahmad et al., 2013). Tenderness is most often exhibited at the site of the attachment of the extensor carpi radialis brevis (ECRB) tendon; however, pain and tenderness on palpation can also be experienced around the prominence of the lateral epicondyle. Pain intensity can be quite variable and manifest as intermittent and mild to constant and severe. The latter can affect a wide range of daily activities and may even occur at night, thereby causing a disturbance in sleep.
