About this trial
The goal of this study is to gather pilot data to help inform a future clinical trial. As such, the investigators will employ a randomized clinical trial design, but data will only be collected on 9 total subjects. Nine subjects will be randomized to 2 split-belt intervention groups (one group where early stance loading is trained and the other where midstance loading is trained) and a placebo group.
The goal of this study is to explore the adaptations in knee loading from a 6-week split-belt training intervention.
The investigators' main question for this aim is:
1. Does knee loading, measured by the sagittal plane knee moment, change to a greater extent in the split-belt treadmill training groups compared to the placebo group? 2. Are there differences in training-related knee loading changes between individuals trained in the early stance vs. midstance loading split-belt training?
