ClinConnect Summary

This clinical trial is testing a new way to help people who have had a stroke walk more evenly by using special treadmills and feedback tools. The study looks at how adding gentle resistance and real-time signals, like sounds or visuals, can improve the strength and movement of the weaker leg. The goal is to find the best combination of these techniques to help stroke survivors walk more smoothly and safely.

The study will include 15 people who have had a stroke at least one month ago and can walk at least 10 meters (about 30 feet), with or without help, as well as 15 healthy adults who can walk on their own. Each participant will spend about two hours walking on different treadmills while experiencing various resistance and feedback settings. The equipment is safe and non-invasive, and the risk is very low. This is a single-session study, meaning participants will only need to attend once. If you or a loved one fits these criteria and is interested, this trial might offer a chance to try new ways to improve walking after a stroke.
