Researchers are investigating how terminal knee extension exercise (TKE) combined with audible cues affects the neuromuscular control of the vastus medialis (VM) muscle in athletes who have recently undergone anterior cruciate ligament (ACL) reconstruction. This study focuses on the immediate impact of a single TKE session synchronized with a metronome to potentially improve muscle activation and motor unit behavior. The research is motivated by rehabilitation guidelines suggesting early use of closed kinetic chain exercises like TKE to prevent knee laxity and reduce pain compared to open chain exercises after ACL surgery. Participants will perform terminal knee extension exercises either with or without audible cues provided by a metronome. These behavioral interventions aim to activate VM muscle activity safely and effectively during the early rehabilitation phase after ACL reconstruction. The study compares the effects of standard TKE exercise to TKE exercise synchronized with metronome pacing, assessing changes in motor unit firing rates. During the study, researchers will measure the average motor unit firing rate from enrollment through two weeks of treatment. Participants' knee function, pain levels, and ability to synchronize with audible cues will be evaluated. The study will monitor participants' neuromuscular responses and safety throughout this period, providing insight into how sensory integration techniques may enhance rehabilitation outcomes after ACL surgery.
