What is the "Prone Hip Extension Test (Staheli test)" used for?

  • Sometime called Staheli test.
  • Prone Hip Extension Test is used to evaluate the hip flexion contracture. 
  • It can also be performed in patients with bilateral hip pathology.

How to perform the "Prone Hip Extension Test (Staheli test)"?

  • The prone hip extension test can be performed on a regular padded examination table.
  • The patient is positioned prone with both hips flexed comfortably over the end of the examination couch.
  • The patient is adequately undressed to allow visualization of the back.
  • The other limb can be held between the examiner’s knees, can be kept on a stool, or can be hung from the edge of the table.
  • The examiner slowly extends the thigh while placing the other hand over the pelvis.

What is the positive result?

  • The point at which the pelvis begins to rise denotes the termination of extension at the hip joint and the beginning of movement at the spine.
  • At this point, the angle between an imaginary horizontal line parallel to the trunk and thigh gives the value of hip flexion contracture.
