"Patients were asked to perform a single leg hop for distance in addition to a cognitive task.~A 10-minute warm-up is required beforehand, followed by three single-leg hop round trips over a distance of 6m to ensure that they are able to perform the exercise.~You start on the healthy side to understand the principles and reassure yourself. The distance covered is measured. This tells us something about the strength of the lower limb. The landing should be assessed qualitatively.~1. Patient balanced on 1 foot, hands crossed over shoulders.~2. Observe a sequence of 5 digits, appearing every 4 seconds, on the computer in front of you.~3. As soon as the 5th digit appears, jump as far as you can.~4. Stabilise 1 time, keeping your hands on your shoulders.~5. Replay the sequence of 5 numbers that appear on the screen, in reverse order."
