What is ITB syndrome primarily caused by?

1. Overuse injury from immobility

2. A tight iliotibial band and abnormal leg movements

3. Direct trauma to the knee

4. A sprain of the thigh muscles

The correct answer is: A tight iliotibial band and abnormal leg movements

Iliotibial Band (ITB) syndrome is primarily caused by a tight iliotibial band and abnormal leg movements. The ITB is a thick band of connective tissue that runs along the outside of the thigh from the hip to the knee. When this band becomes tight, often due to overuse from activities like running or cycling, it can cause friction and irritation at the knee joint, especially during repetitive movements. Abnormal leg movements, such as poor biomechanics during exercise, can exacerbate the problem. For instance, if a person has an improper gait or alignment issues, this can lead to increased tension on the ITB, further contributing to inflammation and pain. Therefore, the combination of a tight iliotibial band and abnormal movement patterns is the primary driver of ITB syndrome, making it crucial for individuals to ensure proper stretching, strengthening routines, and biomechanical assessments are in place to prevent this condition. The other causes mentioned, such as immobility, trauma to the knee, or sprains of thigh muscles, do not directly contribute to the development of ITB syndrome in the same way. While these factors may play a role in overall knee health or other injuries, they are not the primary cause of ITB
