Long Term Split Belt Training for Stroke Recovery

Principal Investigator: Amy Bastian

We recently discovered that the walking deficits of people with post-stroke hemiparesis can be improved on short timescales by adaptation to split-belt treadmill conditions that exaggerate the deficit. The exaggeration drives the nervous system to adapt to correct the deficit, and results in improved walking patterns when the person returns to normal conditions. Here, we plan to investigate how short-term adaptation can be translated into long-term improvement in walking patterns. We will study adults with post-stroke hemiparesis before, during and after training for 12-weeks on a split-belt treadmill or conventional treadmill. This pilot study will provide data to power a full scale clinical trial of walking training.
