This proof-of-concept case series will prospectively use magnetic resonance imaging (MRI) evidence of spared spinal cord neural fibers to guide the selection of 2 research participants to receive a surgically implanted epidural stimulator with the goal of restoring voluntary movement after spinal cord injury (SCI). Because MRI evidence of spared spinal cord neural fibers demonstrated significant relationships with responsiveness to epidural stimulation in SCI in retrospective studies, the proposed study is a traditional feasibility study - a prospective investigation to be used to capture preliminary safety and effectiveness information to determine if MRI can/should be used in planning a future pivotal study.
This is an investigator-initiated proof of concept study performed at the University of Colorado Anschutz Medical Campus (CU Anschutz). This 2-case proof-of-concept study will include 2 research participants with motor-complete SCI to evaluate the performance of the Medtronic epidural stimulator for restoring voluntary movement below the level of injury. Participants will be enrolled at CU Anschutz. Screening data will be reviewed to determine participant eligibility. Two participants who meet all inclusion criteria and none of the exclusion criteria will be entered into the study. The foll…
