Positive findings[edit | edit source]

Leg and/or low back occurring with dorsiflexion and or neck flexion is indicative of dural involvement and/or sciatic nerve irritation

Lack of pain reproduction with dorsiflexion and/or neck flexion is indicative of hamstring tightness or sacroiliac pathology

In clinical practice the outcome test is interpreted with respect to two variables

  1. the maximum angle between the leg and the horizontal plane to which the can be lifted
  2. the pain that is provoked by the movement.[1]
