Instruct the patient to stand on uninvolved leg with hands on hips, behind the start line. Instruct the patient to hop as far forward as possible, landing on the same leg. The patient must control the landing and hold for 2 seconds. If a forward hop cannot be completed safely, and forward leap can be performed jumping from the uninvolved leg to the involved leg. A single-leg forward leap is named for the starting leg (i.e. if patient hops (R) to (L), it would be a (R) leap). 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.
