Nature: timed spinal cord stimulation lets people with chronic paralysis walk again with support

ONWARD Medical/ARC Therapy (ARC-EX / ARC-IM / ARC-BCI)

Stimulation of the lumbar spinal cord timed to each intended step, delivered by an implanted pulse generator, restored voluntary walking within a week in nine people paralyzed for over four years. Some regained control even with stimulation off.

• Stimulation timed to intended step restored voluntary walking
• Participants paralyzed for over four years regained walking within one week
• After months of rehab, some walked with stimulation turned off
• Implanted pulse generator allowed independent use
