Ober’s test 

A clinical test to assess tightness of the iliotibial band (ITB) and the tensor fascia lata (TFL).  Together this muscle and connective tissue travel down the side of the thigh from the top of the pelvis to just below the knee.  The test is performed with the patient lying on the non-painful side, on a table. The examiner stands behind the patient and gently pulls the bent knee backwards.  The examiner attempts to lower (adduct) the leg down toward the table and release it. A positive test is found if the leg remains in the abducted position.
