What this trial studies

This clinical trial investigates the effectiveness of combining a powered exoskeleton with functional electrical stimulation (FES) for patients with chronic spinal cord injuries (SCI). The study aims to evaluate whether this combined approach can enhance walking function and address secondary health issues associated with SCI. Participants will engage in overground gait training using the Ekso exoskeleton while receiving FES to stimulate muscle activity. The trial seeks to fill a gap in existing research by providing a well-designed randomized clinical trial to assess the benefits of this innovative therapy.

Who should consider this trial

Good fit: Ideal candidates include individuals with chronic, incomplete spinal cord injuries who can stand and perform a walking test with or without aids.

Not a fit: Patients with severe spasticity, orthopedic limitations, or contraindications related to the exoskeleton will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve mobility and quality of life for patients with spinal cord injuries.

How similar studies have performed: While there have been numerous non-randomized studies showing positive effects of exoskeleton therapy, this combined approach of exoskeleton and FES is novel and has not been previously tested in a randomized clinical trial.
