What does the Ober test check for?

The Ober test is specifically designed to assess tightness in the tensor fascia latae (TFL) and the iliotibial (IT) band. During this examination, the patient lies on their side while the examiner stabilizes the pelvis and attempts to lower the upper leg. If the leg does not drop smoothly to the level of the table, it indicates tightness either in the TFL or the IT band. This test is commonly used in physical therapy and orthopedic evaluations to identify conditions associated with hip or knee pain, providing insight into the flexibility and function of these structures.

Other answers involve different aspects of muscular and joint function but are not what the Ober test is designed to address. Testing strength of the quadriceps muscle, assessing range of motion in the hip joint, or evaluating pain in the gluteal region do not directly relate to the purpose of the Ober test. Each of these areas may require different tests and assessments altogether.
