Michigan Split-belt Treadmill Training Program to Improve Acute Knee Biomechanics After ACL Reconstruction
Mi-SPA: Michigan Split-belt Adaptation Paradigm to Improve Knee Loading After Anterior Cruciate Ligament Reconstruction (Aim 2)
University of Michigan
30 participants
Oct 29, 2024
INTERVENTIONAL
Conditions
Summary
The goal of this study is to determine short-term adaptations (aftereffects) in knee loading after a 20-minute split-belt treadmill training session in patients with ACL reconstruction. Our main question for this aim are: 1. Are training-mediated aftereffects in the knee joint moment greater for tied-belt walking or split-belt walking? 2. Are training-mediated aftereffects in the knee joint moment different between subjects who train early stance knee loading versus subjects who train mid-stance knee loading?
