This phenomenon, commonly known as 'arthrogenic motor inhibition' (AMI), is a major limiting factor for recovery and rehabilitation following an anterior cruciate ligament tear, as well as a potential cause of functional disability if left undiagnosed and untreated. Indeed, motor inhibition that persists during the early months of rehabilitation could lead to under-activation of the quadriceps and over-activation of the hamstrings (the muscles at the back of your thigh).\n\nIt is of interest to assess, during the rehabilitation phase, the contraction capacity of the various quadriceps and hamstring muscles in the operated limb compared with the unaffected limb in patients who have undergone anterior cruciate ligament surgery and who experience post-operative motor inhibition, and in patients who have undergone anterior cruciate ligament surgery but do not experience post-operative motor inhibition. This is why this study has been initiated.",[62],"ACL - Anterior Cruciate Ligament Rupture",[64,65,66,67],"ACL rupture","AMI","electromyography","thigh","NOT_YET_RECRUITING","2026-06-15",{"date":71,"type":72},"2026-06-22","ACTUAL",{"date":74,"type":56},"2026-09",{"date":76,"type":56},"2027-10",{"name":5,"class":6},1]
