Training program to improve knee biomechanics after ACL reconstruction
Mi-SPA: Michigan Split-belt Adaptation Paradigm to Improve Knee Loading After Anterior Cruciate Ligament Reconstruction (Aim 2)
This study tests if a special treadmill training can help people who had ACL surgery improve their knee movement and reduce the chance of getting hurt again.

What this trial studies
This study aims to evaluate the effects of split-belt treadmill training on knee loading in patients who have undergone ACL reconstruction. Participants will engage in a 20-minute training session where treadmill belts operate at different speeds to promote adaptive changes in gait mechanics. The study will compare the knee joint moments between those using split-belt training and tied-belt training, focusing on early and mid-stance loading. The goal is to identify effective rehabilitation strategies to reduce the risk of re-injury and long-term complications such as osteoarthritis.
Who should consider this trial
Good fit: Ideal candidates are individuals aged 14-45 who have recently undergone ACL reconstruction with autograft.
Not a fit: Patients with previous knee injuries, surgeries, or those who had ACL reconstruction with an allograft will not benefit from this study.
Why it matters
Potential benefit: If successful, this training program could enhance knee function and reduce the risk of re-injury in patients recovering from ACL reconstruction.
How similar studies have performed: Previous studies have shown that split-belt treadmill training can significantly improve gait biomechanics in various populations, suggesting potential success for this approach in ACL rehabilitation.
