Overview

Arthrogenic muscle inhibition (AMI) is the key neurophysiological cause of impeding quadriceps activation following anterior cruciate ligament reconstruction (ACLR). Blood flow restriction training (BFRT) may induce neuroplasticity whereas the neurophysiological responses remain uncertain. In this study, we aimed to explore the effects of constant pressure blood flow restriction training (CP-BFRT) on neurophysiological responses and physical function. Patients will receive the same standardized progressive physical rehabilitation for 2 weeks after the surgery and then start the BRFT or sham BRFT intervention for the following 12 weeks.
