About this trial

This trial is enrolling individuals with incomplete spinal cord injuries to test the effect of using a more precise measurement of voluntary muscle activity during robot-assisted walking. The overall aim is to improve the detection of residual muscle activity of the leg muscles and thus optimize the assistance and safety of robotic devices. The study combines the common practice of electromyography (EMG) with ultrasound imaging. If included, participants will undergo different seated posture tasks and walking tasks using either a powered ankle exoskeleton or an functional electrical stimulation (FES) system of the leg muscles. Final testing will be performed after 8 sessions being performed. Each session may last up to 4 hours.
