What is a common cause of Iliotibial Band Friction Syndrome?

Iliotibial Band Friction Syndrome (ITBFS) is often associated with repetitive activities that involve extensive knee flexion and extension, such as running and cycling. These activities can lead to irritation and inflammation of the iliotibial band, a thick band of tissue that runs along the outside of the thigh and crosses the knee joint. The repetitive motion can cause the band to rub against the femur, leading to pain and discomfort.

Excessive running and cycling often involve continuous movement that places stress on this band, making it a primary cause of the syndrome. Proper conditioning, technique, and adequate rest can help mitigate the risk of developing this condition.

The other options do not directly relate to the biomechanical stresses that lead to this specific syndrome. For example, wrist overuse primarily affects the upper extremities and does not involve the iliotibial band. Prolonged sitting may lead to hip tightness or weakness but is not a primary driver of ITBFS. Similarly, while insufficient warm-up can contribute to a wide variety of injuries, it is more of a general risk factor and not a specific cause of Iliotibial Band Friction Syndrome on its own.
