This Spinal Cord Associative Plasticity Study (SCAP) is investigating whether combined brain and spinal cord electrical stimulation can strengthen neural pathways and potentially improve arm and hand function after cervical spinal cord injury (SCI). Researchers aim to enhance remaining connections between the brain and spinal cord by pairing cortical and spinal stimulation, a technique known as Spinal Cord Associative Plasticity (SCAP). The study also aims to better understand spinal cord function, determine how electrical stimulation affects spinal excitability, and examine changes in neural function following cervical decompression surgery.
Participants include uninjured volunteers, individuals with chronic cervical SCI, and individuals with cervical myelopathy or radiculopathy requiring decompressive surgery. SCI and myelopathy participants will have partially retained motor function in the hand.
