It is theorized reduced corticospinal excitability contributes to quadriceps dysfunction after knee injury and joint disease. Current rehabilitation does not directly target the alterations in corticospinal excitability, which may limit recovery. Operant conditioning is an emerging approach capable of increasing corticospinal excitability by directly targeting the corticospinal pathways. However, it remains to be determined whether operant conditioning of the corticospinal pathway may improve corticospinal function after knee trauma. Therefore, this study will evaluate the ability of operant up-conditioning of the corticospinal pathway to improve corticospinal function after ACL reconstruction.
The purpose of this study is to examine if the changes in corticospinal function that accompany ACL reconstruction can be improved through a form of mental coaching and encouragement, known as operant conditioning.
