Clinical Trial Summary

Investigators propose to demonstrate that epidural stimulation (ES) can be used to recover significant levels of autonomic control of cardiovascular, urinary and sexual function as well as the ability to voluntarily control leg movements below the injury level. This intervention would provide an immediate therapeutic alternative to individuals who now have no recourse for treatment. In addition investigators suggest to prove on functional magnetic resonance imaging if there are some significant changes before and after the stimulation.

Outcome

Type Measure Description Time frame Safety issue
Primary Brain functional connectivity Researchers want to describe if there are some changes on functional MRI of the spinal cord and brain before and after stimulation. With functional MRI in rest and task condition, the functional connectivity (FC) is examined. 1 year after implantation
Primary Change from baseline of lower extremity independence time during after 1 year of stimulation Researchers will measure the amount of time individuals are able to stand without manual assistance (independently). 1 year after stimulation (360 training sessions)
Secondary Change in trunk stability restoration Trunk control stability test in individuals with spinal cord injury (SCI) 6 month and 1 year after implantation
Secondary Neurogenic bladder symptoms will be measured using the Neurogenic Bladder Symptom Score (NBSS). Assessment of neurogenic bladder symptoms will be performed to assess the impact of long term eSCS on this measure. The score measures bladder symptoms across 3 different domains: incontinence (scored 0-29), storage and voiding (scored 0-22), and consequences (scored 0-23), with higher scores representing worse symptoms. 3 month, 6 month, 9 month, 12 month
Secondary Sexual function as measured by the Sexual Function Questionnaire The Sexual Function Questionnaire (SFQ) is a self-report outcome measure of sexual function. 3 month, 6 month, 9 month, 12 month
Secondary Change in sense of wellbeing as measured by the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire The WHOQOL-BREF assesses quality of life (QOL) within the context of an individual's culture, value systems, personal goals, standards and concerns. The higher score in the questionnaire means better quality of life for patient. 3 month, 6 month, 9 month, 12 month
Secondary Symptoms of spasticity will be measured by Modified Ashworth spasticity test The modified Ashworth scale is the most universally accepted clinical tool used to measure the increase of muscle tone. 3 month, 6 month, 9 month, 12 month
Secondary Neurogenic bowel symptoms will be measured using the Neurogenic Bowel Dysfunction (NBD) score. Assessment of neurogenic bowel symptoms will be performed to assess the impact of long term eSCS on this measure. Scores can range from 0-47, with a higher score representing more severe dysfunction. 3 month, 6 month, 9 month, 12 month
Secondary Reduction of neuropathic pain We will measure neuropathic pain by the Neuropathic Pain Questionnaire (NPQ) 3 month, 6 month, 9 month, 12 month
Secondary Change in BP during the head up tilt test (HUTT) During HUTT, participants will be passively moved to approximately 60° upright stand position by the investigators using the tilt table. Using epidural spinal cord stimulation (eSCS) to activate spinal sympathetic circuitry and mitigate low resting BP and orthostatic hypotension (OH) and continuous beat-by beat BP monitoring via finger photoplethysmography. 6 month -1 year
