Ober’s test. Used in diagnosing iliotibial band syndrome.
“The Ober’s test can be used to assess tightness of the iliotibial band. With the patient lying on the side with the unaffected side down and the unaffected hip and knee at a 90-degree angle, the examiner stabilizes the pelvis, then abducts and extends the affected leg until it is aligned with the rest of the patient’s body. The affected leg is lowered into adduction. If the iliotibial band is normal in length and unaffected, the leg will adduct and the patient will not experience pain. If the iliotibial band is tight, the leg will remain in the abducted position and the patient may have lateral knee pain. A tight iliotibial band contributes to the excess friction placed on the iliotibial band as it slides over the femoral condyle during flexion and extension of the knee.”
