BACKGROUND: Operant conditioning of motor evoked torque (MEP HYPOTHESIS: Quadriceps MEP STUDY DESIGN: Randomized controlled laboratory study. LEVEL OF EVIDENCE: Level 2. METHODS: Thirty-six participants were assessed during a single session of an operant conditioning protocol. Participants were randomized into 1 of 3 groups for stimulus intensity used during operant conditioning based on the participant's active motor threshold (AMT: 100%, 120%, and 140%). Quadriceps MEP RESULTS: Participants with ACL reconstruction could upcondition their MEP CONCLUSION: Operant conditioning can elicit short-term neural adaptations in ACL-reconstructed patients. Future operant conditioning paradigms may effectively use any of the 3 stimulus intensities studied herein. CLINICAL RELEVANCE: Operant conditioning may be a feasible approach to improve corticospinal excitability after ACL reconstruction.
