How is the Ober Test performed?

• A. Patient in standing position, with one leg lifted straight up
• B. Patient lying supine and extending legs
• C. Patient side lying, with knee flexed at 90 degrees and stabilized pelvis
• D. Patient seated and leaning forward

Answer: (C)

The Ober Test is specifically designed to assess the tightness of the iliotibial band and the tensor fascia lata. This orthopedic test is performed with the patient in a side-lying position to appropriately target the lateral aspects of the hip and thigh.

In this test, the patient lies on their side, and the examiner stabilizes the pelvis while the patient's top knee is flexed at 90 degrees. The examiner then slowly abducts and extends the top leg while allowing it to drop towards the examination table. If the leg cannot drop past the horizontal plane or remains elevated, it indicates tightness in the iliotibial band.

The choice of position is crucial for the effectiveness of the test, as the side-lying position allows for accurate assessment of hip abduction and the tension in the associated fascia. Other positions, such as standing or supine, would not provide the appropriate mechanics to assess the iliotibial band effectively.
