Evaluation of the Evolution of Proprioceptive Reweighting Abilities Following Anterior Cruciate Ligament Reconstruction Surgery
Sponsor: University Hospital, Brest
Summary
Anterior cruciate ligament (ACL) injury is the most common knee injury among athletes who play contact sports involving pivoting. ACL reconstruction (ACLR) combined with rehabilitation is the standard treatment for ACL tears in athletes, and rehabilitation is one of the keys to success. The overall return to sport rate is 80%, but the return to pre-injury level of sport is only 65% and the return to the same level of competition is only 55%. The recurrence rate is close to 20%. During rehabilitation and sports practice, proprioceptive information is essential for adjusting the muscle sensorimotor loop and enabling optimal movement. Athletes can thus be classified as plastic or rigid . Our hypothesis is to show that the proportion of "plastic" patients 9 months post-operative following ACL reconstruction is higher than that found in the same population 3 months post-operative, thus demonstrating the progression of proprioceptive integration abilities after ACL reconstruction surgery.

Interventions
ReproEVO intervention
After the inclusion visit, each assessment will include an examination of standing balance in two support conditions: hard floor or soft floor and two conditions of vibration of the Achilles tendons or lumbar muscles, performed randomly over five trials for each condition. The subjects stand with their eyes covered by an opaque mask. Vibrators are positioned at both locations and vibrated randomly after a trial without recording to perceive the destabilizing effect induced by the vibration. The data is recorded using a force platform on the floor. Subjects will be seated and strapped into a rigid device attached to their leg. The device is connected to a motor that maintains a constant speed. Maximum strength will be measured at two different speeds. Finally, at each assessment, the subjects will complete questionnaires about their fear of pain, their assessment of their knee's capabilities, and the activities they engage in.
