Brain-Computer Interface Training to Improve Muscle Activation After Orthopedic Surgeries Including ACL, Knee, and Hip Replacements

What this Trial Is About

Researchers are investigating whether neurofeedback visualization training can help improve muscle activation and speed up recovery after orthopedic surgeries such as anterior cruciate ligament reconstruction, total knee arthroplasty, total hip arthroplasty, and hip arthroscopy for femoroacetabular impingement. This phase 2 trial evaluates the addition of brain-computer interface technology to standard physical therapy to address Arthrogenic Muscle Inhibition AMI, a neurological condition that limits muscle activation after surgery and slows rehabilitation. Participants will be randomly assigned to receive either standard post-surgical rehabilitation therapy alone or combined with neurofeedback visualization training using the i-BrainTech platform. This training uses a cap with EEG sensors to monitor brain activity while participants mentally visualize rehabilitation movements. The EEG signals control a virtual avatar providing real-time feedback in a video game format, aiming to enhance motor cortex activation and muscle control. Training sessions occur twice weekly for eight weeks post-surgery alongside standard physical therapy. During the study, participants will attend follow-up visits at 2, 4, and 6 months after surgery for motion analysis, strength testing, and questionnaires about recovery. Assessments include surface electromyography, markerless motion capture, and strength measurements normalized for body size. Researchers will measure knee extensor and hip abductor strength as primary outcomes and evaluate joint movement, muscle activation, flexibility, and patient-reported outcomes as secondary outcomes. Participants recovery progress will be closely monitored over six months to assess the interventions impact.
