Ankle Robotics for Error Augmentation After Stroke

Brief Summary

The goal of this pilot clinical trial is to test whether training with a portable ankle robot improves ankle push-off and walking speed in adults with chronic stroke who have ankle weakness. The study will also evaluate whether the device is safe and practical to use during walking rehabilitation. The main questions it aims to answer are: Does training with the portable ankle robot improve paretic ankle propulsion during walking? Does training with the portable ankle robot improve walking speed at self-selected and fast walking speeds? Participants will: Complete 30 training sessions of treadmill and overground walking while wearing the portable ankle robot, 3 to 4 times per week over 8 to 9 weeks Complete walking and movement assessments before training, after 15 sessions, and after 30 sessions Walk at self-selected and fast speeds while researchers measure ankle propulsion, gait symmetry, and walking speed
