About this trial

This feasibility trial is enrolling 12 participants with spinal cord injury to test the effect of an epidural spinal stimulation (eSS) system on walking function. eSS is an invasive technique that uses an implanted electrode placed next to the spinal cord to deliver electrical stimulation aimed at modifying spinal cord function. If included, participants will be assigned to either the subacute (< 6 weeks) or chronic (> 1 year) group, based on time since injury, and receive ARC-IM electrical stimulation to the lumbosacral (lower) region of the spinal cord. Final testing for device safety and walking function will be performed up to 6 years.
