Final answer:
The muscle associated with pain at the lateral femoral epicondyle during knee ROM is the iliotibial (IT) band. This condition is known as iliotibial band syndrome (ITBS) and is commonly seen in athletes. Treatment includes RICE, stretching, and strengthening exercises.
Step-by-step explanation:
The muscle associated with pain at the lateral femoral epicondyle during knee range of motion (ROM) is the iliotibial (IT) band. The IT band is a long tendon that runs down the outside of the thigh and attaches to the lateral epicondyle of the femur. When the knee is extended or flexed, the IT band can rub against the lateral femoral epicondyle, causing pain or discomfort.
This condition is commonly known as iliotibial band syndrome (ITBS) and is a common overuse injury among athletes who engage in activities that involve repetitive bending and extending of the knee, such as running or cycling. In addition to pain at the lateral femoral epicondyle, other symptoms of ITBS may include swelling, tenderness, and a clicking or popping sensation.
Treatment for ITBS typically involves rest, ice, compression, and elevation (RICE) to reduce inflammation and pain. Stretching and strengthening exercises for the IT band and associated muscles, such as the hip abductors, can also help alleviate symptoms. In severe cases, medical intervention, such as physical therapy or corticosteroid injections, may be necessary.
