Which test identifies a positive IT band friction syndrome?

Ober's test is specifically designed to assess tightness in the iliotibial band and is directly relevant to diagnosing conditions like IT band friction syndrome. In this test, the individual lies on their side while the examiner stabilizes the pelvis. The examiner then lifts the upper leg and allows it to fall back towards the table. If the leg does not drop below the level of the table, it indicates tightness in the iliotibial band, which can contribute to friction and pain on the lateral aspect of the knee, a hallmark symptom of IT band friction syndrome.

The other tests listed do not evaluate the iliotibial band. For example, Finkelstein’s test evaluates for De Quervain's tenosynovitis affecting the tendons of the thumb, Phalen's test is used to diagnose carpal tunnel syndrome, and Craig's test assesses femoral anteversion. Thus, Ober's test is uniquely suited for identifying issues related to the iliotibial band, making it the correct choice for this condition.
