Brief Summary

After reconstruction of the anterior cruciate ligament, the aim for the vast majority of sportspeople is to return to the field. To date, 65% of patients who have undergone ACL rehabilitation return to their previous level, and 55% return to competition. To achieve this, physiotherapy sessions need to prepare the return to sport as well as possible, by simulating the cognitive demands (reading the game, double task, etc.) that might be encountered on the pitch. Tests to assess the athlete's performance do exist, in order to optimise this return to sport, but they do not include the cognitive tasks that are present in sport. The high cognitive demands of the sporting environment therefore justify the inclusion of cognitive tasks in these return to sport tests. The aim of this research is to assess the impact of the cognitive task on the performance of a return to sport test following ACL reconstruction. Patients who have undergone ACL reconstruction and healthy subjects will therefore be given a return to sport test called the 'Single Leg Hop for Distance' with and without a cognitive task in order to observe the influence of the cognitive task on the results of the hop.

Including healthy subjects in this study will make it possible to study the impact of the cognitive task in these subjects, who have no neurophysiological dysfunction linked to ACL reconstruction.

The aim of this study is therefore to try to develop the return to sport tests currently described in the literature by proposing a new, improved test that takes account of the cognitive dimension, which is omnipresent in the sporting environment.

Study Groups

Control group: SLHD then SLHD with cognitive task

This control group, made up of healthy subjects, will perform a single leg hop for distance and then one week later will perform a single leg hop for distance plus a cognitive task.

Intervention 1 administered : Other: Single leg hop for distance. Intervention 2 administered : Other: Single leg hop for distance plus cognitive task.

Group Type: EXPERIMENTAL

Single leg hop for distance

Intervention Type: OTHER

Patients will have to perform a Single leg hop for distance.

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. Jump as far as possible.

3. Stabilise 1 time, keeping hands on shoulders.

Single leg hop for distance plus cognitive task

Intervention Type: OTHER

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.

Control group: SLHD with cognitive task then SLHD

This control group, made up of healthy subjects, will perform a single leg hop for distance plus a cognitive task and then one week later will perform a single leg hop for distance.
