The feasibility of using exoskeletal-assisted walking with epidural stimulation: a case report study

This study explores using spinal cord epidural stimulation (SCES) to help people with spinal cord injuries (SCI) walk better with exoskeletons. SCES has shown promise in helping restore movement, but it usually requires a lot of intensive rehab. The researchers wanted to see if combining SCES with exoskeletal-assisted walking (EAW) could be a more practical approach. The study involved a person with a C7 complete SCI who underwent 12 weeks of EAW with SCES. Over the course of the study, the amount of assistance the exoskeleton provided was reduced, and the researchers monitored the participant's muscle activity and how hard they felt they were working. The results showed that the participant was able to take more steps on their own and had improved muscle activity patterns during walking. They also felt like they were working harder when using SCES, which suggests it was increasing the intensity of the exercise. The study suggests that using SCES with EAW may be a feasible way to help people with SCI regain some motor function.

• 1
  After 24 sessions (12 weeks) of EAW swing assistance decreased from 100% to 35% in a person with C7 complete SCI.
• 2
  Electromyographic pattern improved during EAW, reflecting the subject’s ability to rhythmically activate paralyzed muscles.
• 3
  Rate perceived exertion increased during EAW with SCES compared to stepping without SCES.
