What this Trial Is About
Researchers are investigating spinal cord stimulation (SCS) as a method to improve motor and autonomic function in adults with chronic complete spinal cord injury (SCI). This study aims to determine whether applying SCS to both the injury site and the lumbrosacral spinal cord can enhance motor recovery compared to stimulation of the lumbrosacral area alone. Previous studies have shown that SCS can activate previously paralyzed muscles and help restore function in chronic paralysis. Participants will undergo standard surgery to implant spinal cord stimulators with leads placed at the injury site and the lumbrosacral spinal cord. The study includes three phases of intervention lasting three months each: first, activation of SCS over the lumbrosacral spinal cord; second, activation over the injury site only; and third, activation over both areas simultaneously. Throughout all phases, participants will receive physiotherapy targeting lower limb muscles and engage in exoskeleton training for 4 to 5 hours weekly. During the trial, participants will be assessed for improvements in standing, stepping, walking ability, gait, and lower limb sensation from baseline to three months after the third phase. Researchers will also monitor changes in pain intensity, quality of life, psychological symptoms, and neuropathic pain. The total intervention and follow-up period includes nine months of stimulation phases plus three months of post-treatment observation, with evaluations conducted at regular intervals to track progress.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 1 day
Participants undergo surgery to implant the spinal cord stimulator leads at the injury site and lumbrosacral spinal cord.
1 surgical visit (in-person)
Duration - Up to 9 months total (3 months per phase)
Participants receive spinal cord stimulation in three sequential phases to improve motor function. Phase 1 activates stimulation over the lumbrosacral spinal cord for 3 months. Phase 2 activates stimulation over the injury site for 3 months. Phase 3 activates stimulation over both sites for 3 months. Physiotherapy and exoskeleton training are provided throughout.
Regular visits during each 3-month phase for stimulation and physiotherapy
Duration - 3 months
Participants are monitored for changes in standing, stepping, pain intensity, quality of life, and neurological function up to 3 months after the final treatment phase.
