Analysis of quadriceps arthrogenic muscle inhibition of acl injury with decomposed electromyography

This abstract has open access
Abstract Summary
Arthrogenic muscle inhibition (AMI) is a known phenomenon that causes reflex inhibition of muscles that surround the injured joint. The mechanisms of AMI remain unclear. Novel decomposed electromyography (dEMG) technology may reveal motor unit (MU) firing frequency and recruitment of AMI. EMG was collected longitudinally from controls and anterior cruciate ligament (ACL) injured subjects. Results reveal highest MU dysfunction at 6 months, with MU dysfunction also present at pre-surgery and 12 months, compared to controls.
