From the Research

The Vivistim device is not currently approved for treating spinal cord damage and should not be used as a primary treatment for enhancing motor recovery in spinal cord injury patients. Vivistim is specifically designed to treat upper limb mobility issues in stroke survivors through vagus nerve stimulation (VNS) paired with rehabilitation exercises, targeting brain plasticity rather than addressing spinal cord injuries directly 1. Spinal cord damage involves different mechanisms and pathways than stroke-related brain damage, necessitating specialized rehabilitation approaches, potentially including epidural stimulation devices specifically designed for spinal cord function 2.

Key Considerations

  • The underlying mechanisms of spinal cord injuries and stroke-related brain damage differ significantly, requiring distinct neurostimulation approaches 3.
  • Epidural spinal cord stimulation has shown promise in restoring lower extremity and other neurological functions in individuals with motor complete spinal cord injury, highlighting the importance of targeted therapies 2.
  • Transcutaneous electrical spinal stimulation has also demonstrated potential in promoting long-term recovery of upper extremity function in chronic tetraplegia, further supporting the use of specialized spinal cord stimulation techniques 4.

Recommendations

  • Patients with spinal cord injuries should seek treatments specifically developed for spinal cord rehabilitation rather than devices like Vivistim that target brain plasticity through vagal pathways.
  • Healthcare providers should consider the latest evidence on epidural spinal cord stimulation and transcutaneous electrical spinal stimulation when developing rehabilitation plans for spinal cord injury patients 2, 4.
  • Further research is needed to fully understand the mechanisms and potential benefits of different neurostimulation approaches for spinal cord injury rehabilitation, but current evidence supports the use of specialized spinal cord stimulation techniques over devices like Vivistim 1, 3, 2, 4, 5.
