Brief Summary:
This study will evaluate a method to optimize parameter settings in epidural spinal cord stimulation used to recover lower extremity volitional movement. The study will also characterize improvement in autonomic function (such as blood pressure control) and other functions related to spinal cord injury.

Condition or disease Intervention/treatment Phase
Spinal Cord Injuries Paraplegia, Complete Device: Epidural Spinal Cord Stimulation Not Applicable

Detailed Description:

Epidural spinal cord stimulation for the purpose of facilitating volitional movement is a new and novel neuromodulatory treatment. Epidural SCS has a long history of use for chronic pain with established medical device platforms. The purpose of this study is to investigate and establish the use of SCS for volitional movement. Specifically, establishing the disinhibitory effect of SCS in a greater population with inherent greater variability.

In addition to establishing the disinhibitory effect of SCS for cSCI, our study attempts to explore the parameter space of the spinal cord stimulator platforms in order to optimize stimulation settings for patients through the creation of a clinical decision support system (CDSS). Preliminary evidence suggests benefit to autonomic function, and this study also begins to explore the effects of SCS on cardiovascular function, urinary function, psychiatric outcomes, and quality of life, which all offer significant potential for patients suffering from chronic spinal cord injury.

Ages Eligible for Study:   22 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 22 years of age or older
  • Able to undergo the informed consent/assent process
  • Stable, motor-complete paraplegia
  • Discrete spinal cord injury between C6 and T10
  • ASIA A or B Spinal Cord Injury Classification
  • Medically stable in the judgement of the principal investigator
  • Intact segmental reflexes below the lesion of injury

Exclusion Criteria:

  • Diseases and conditions that would increase the morbidity and mortality of spinal cord injury surgery (e.g. cardiopulmonary issues)
  • Inability to withhold antiplatelet/anticoagulation agents perioperatively
  • Significant dysautonomia that would prohibit rehabilitation or assisted standing or any history of CVA or MI associated with autonomic dysreflexia. A single tilt table test with syncope, presyncope, or SBP < 50 or >200.
