Michigan Split-belt Treadmill Training Program to Improve Acute Knee Biomechanics After ACL Reconstruction

Description

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?

Conditions
