Ober Test

 Ober Test

  • The Ober Test evaluates a tight, contracted or inflamed Tensor Fasciae Latae (TFL) and Iliotibial band (ITB).

  • The patient should be in side-lying with the affected side up.
  • Bottom knee and hip should be flexed to flatten the lumbar curve.
  • The examiner Stands behind the patient and firmly stabilizes the pelvis/greater trochanter to prevent movement in any direction.
  • Then Grasps the distal end of the patient’s affected leg with his other hand and flexs the leg to a right angle at the knee
  • Extends and abduct the hip joint.
  • Slowly lowers the leg toward the table -adduct hip- until motion is restricted.
  • Ensures that the hip does not internally rotate and flex during the test and the pelvis must be stabilized. As allowing the thigh to drop in flexion and internal rotation would ‘give in’ to the tight TFL and not accurately test the length.

  • If the ITB is normal, the leg will adduct with the thigh dropping down slightly below the horizontal and the patient won’t experience any pain; in this case, the ober test is called negative.
  • If the ITB is tight, the leg would remain in the abducted position and the patient would experience lateral knee pain, in this case, the ober test is called positive.
