Single-leg 90° Rotational Medial/Lateral Hop (RTP Testing)


   Instruct patient to stand facing parallel to the start line on the uninvolved limb with hands on hips. The patient will hop off of uninvolved limb as far as possible, performing 90° medial or lateral turn to land facing forward, maintaining hands on hips. Patient will be hopping for distance, measured from the heel. Instruct patient to hop first, prior to turning, to avoid twisting at the knee. The single-leg forward leap will be filmed from a frontal view.


    Measure the distance closest to start line (from patient’s heel). Perform three repetitions for each leg. All measurements are made in centimeters.
