A common overuse injury to the elbow is called tennis elbow or lateral epicondylitis (LE). LE is a condition that causes substantial discomfort and dysfunction in the upper extremity. Thermal and electrical agents are examples of conservative techniques. It is a significant public health concern since it frequently occurs due to occupation. It also happens in recurrent upper extremity motions including desktop use, weight training, forceful forearm movements, and repetitive vibratory movements, which are the most common activities performed by an engineer. LE leads to lateral epicondylar pain, which is irritating due to inflammation of the extensor muscle origin, and also activities of daily living are restricted. It is not only seen in players with racquet sports but then most of the males and females are affected in the fourth and fifth decades, leading to limitations in daily work, activity, and household work. Rehabilitation seems the most effective treatment yet in acute and chronic conditions if later the pain does not subside then rest, injectables, and nonsteroidal anti-inflammatory drugs are the options to be taken. Physiotherapeutic rehabilitation plays a significant role in LE.
