Brain-Computer Interface Training for Muscle Activation After Orthopedic Surgery
This study is investigating if a special type of brain training, called neurofeedback visualization training, can help patients recover muscle strength faster after orthopedic surgeries like knee or hip replacement. After these surgeries, some patients experience Arthrogenic Muscle Inhibition (AMI), which makes it hard to fully activate their muscles. This trial compares patients receiving standard physical therapy to those who also use a device that reads brain signals (EEG) while they imagine performing rehabilitation exercises. The goal is to see if this brain training improves knee and hip muscle strength at 2, 4, and 6 months after surgery. You may be able to join if you are over 18, can participate in the training, and are having one of the four specified orthopedic procedures.
- Study design
- This interventional study plans to enroll 240 participants. It compares standard physical therapy to standard physical therapy combined with visualization training with neurofeedback.
- What's involved
- Not specified in the trial record.
- Compensation
- Not stated in the trial record.
- Follow-up
- Participants will be followed for at least 6 months, with muscle strength measured at 2, 4, and 6 months after surgery.

What this trial measures
- Knee extensor strength2, 4 and 6 months
ACLR and TKA groups: Maximal isokinetic knee extensor strength (Newtons/BMI). Maximal isokinetic knee extensor strength will be assessed using standardized dynamometry procedures with Biodex Isokinetic Dynamometer (Biodex System 3) at 2, 4 and 6 months after surgery. Each participant will perform three to five maximal voluntary isometric contractions of the knee extensors. The average of the peak torque values will be used for analysis. To account for individual differences in body size, values will be normalized to the participant's body mass index (Newtons/BMI). Body Mass Index (BMI) = weight (kg) / \[height (m)\]². The first assessment will occur at 2 months to ensure patient safety and measurement consistency, as early postoperative conditions (e.g., pain, swelling) could compromise the reliability and validity of strength testing.
- Hip Abductor Strength2, 4 and 6 months
Hip arthroscopy and THA: Maximal isokinetic hip abductor strength (Newtons/BMI). Maximal isokinetic hip abductor strength will be assessed using standardized dynamometry procedures with Biodex Isokinetic Dynamometer (Biodex System 3) at 2, 4 and 6 months after surgery. Each participant will perform three to five maximal voluntary isometric contractions of the hip abductors. The average of the peak torque values will be used for analysis. To account for individual differences in body size, values will be normalized to the participant's body mass index (Newtons/BMI). Body Mass Index (BMI) = weight (kg) / \[height (m)\]². The first assessment will occur at 2 months to ensure patient safety and measurement consistency, as early postoperative conditions (e.g., pain, swelling) could compromise the reliability and validity of strength testing.
