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 following treatment regimen will be used: epidural stimulation + 6 months of intensive outpatient physical therapy.
Total duration of study participation will be 8 months.

|---|---|---|---|
| Epidural stimulation with Physical Therapy | Experimental | Stimulation parameters will be optimized for each lower extremity and joint movement. During physical therapy sessions, electrode configurations may be adjusted as needed to optimize stimulation frequencies, and voltage intensity ranges to best enable voluntary control of lower extremity (ankle, knee, and hip) flexion and extension, as well as standing. Intensive physical therapy will consist of 3 visits per week over the course of 6 months directed by a licensed physical therapist with over a decade of experience working with individuals with spinal cord injury, and the epidural stimulator will be ON continuously during these sessions. Physical therapy will involve neurorehabilitation to facilitate voluntary lower extremity movement in the presence of stimulation, with the research participants in the supine, seated, and standing positions. |

| International Standards for Neurological Classification of Spinal Cord Injury lower extremity motor scores (ISNCSCI-LEMS) | International Standards for Neurological Classification of Spinal Cord Injury lower extremity motor scores (ISNCSCI-LEMS) will be used to measure the degree of voluntary motor change. LEMS is conducted with the participant lying supine and five key muscle groups on each side are tested for their ability to contract against gravity and resistance. ISNCSCI motor testing has been shown to have adequate to excellent interrater reliability in individuals with spinal cord injury, and is a valid tool for this population. | at day 1, at month 7, and at month 8 |

| The abbreviated World Health Organization Quality of Life (WHOQOL-BREF) | The abbreviated World Health Organization Quality of Life (WHOQOL-BREF) instrument will be used to measure the degree of participants' perception of change in quality of life after stimulator implantation. The WHOQOL-BREF assesses quality of life within the context of an individual's culture, value systems, personal goals, standards, and concerns. It has been studied and highly recommended for individuals with spinal cord injury. Scores for the abbreviated World Health Organization Quality of Life instrument range from 0 - 100, with higher scores indicating a better outcome. |
