Brain Controlled Spinal Cord Stimulation in Participants With Cervical Spinal Cord Injury for Upper Limb Rehabilitation

NCT05665998 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 3

Last updated 2026-04-23

No results posted yet for this study

Summary

Cervical spinal cord stimulation can elicit arm and hand movements through recruitment of proprioceptive neurons in the dorsal roots. In participants with cervical spinal cord injury, the spare roots bellow the lesion can be used to reactivate motor function. Decoding of motor intentions can be achieved through implantable electrocorticography (ECoG) devices.

In this study, the investigators will use an investigational system using ECoG signal recording over the motor cortex to drive muscle specific electrical epidural spinal cord stimulation (EES). The investigators will assess the safety and preliminary efficacy of this system in 3 participants.

Conditions

  • Cervical Spinal Cord Injury
  • Tetraplegia

Interventions

DEVICE

ARC-BSI Cervical system

Unilateral implantation of a 64 channel - ECoG array over the sensory motor cortex combined with an implantation of 32 channel spinal cord stimulation system over the cervical region. The system decodes the motor attempts of the participant and translates those intentions into modulation of electrical stimulation.
