VALSE: Integration of Neuromodulation and Exoskeleton Systems for Mobility in Individuals With Chronic Spinal Cord Injury

The purpose of this clinical study is to evaluate the preliminary safety and feasibility of using the VALSE system, which combines spinal cord stimulation with the TWIICE robotic exoskeleton, to support motor recovery and reduce reliance on laboratory-based equipment during rehabilitation in participants with traumatic spinal cord injury. The TWIICE exoskeleton is integrated through the NR system, a platform developed by EPFL. The goal is to assess the clinical safety and practical application of this combined neuroprosthetic approach in a small number of participants, in order to guide future refinements of the device and protocol, support the development of scalable interventions integrating spinal stimulation with robotic assistance, and inform strategies for delivering rehabilitation in more accessible, real-world environments.
