Cuneiform Nucleus (CnF) Deep Brain Stimulation for Gait Facilitation Following Spinal Cord Injury
University of Miami
Summary
This is a study about deep brain stimulation (DBS) as an investigational treatment for walking impairment following spinal cord injury (SCI). The purpose of this study is to assess the feasibility and inform on the safety, and efficacy of CnF DBS to improve gait in SCI patients with incomplete injury who cannot effectively walk overground
Eligibility
- Age range
- 22–70 years

- Healthy volunteers
- No
Inclusion Criteria: * Male or female subjects between ages of 22-70 * At least 1 year post SCI * Confirmed SCI according to SCI clinician according to clinical history and the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) / American Spinal Injury Association (ASIA) criteria as documented in the American Spinal Injury Association Impairment Scale (AIS) on examination. Other disorders of gait will be excluded by history and a neurological examination. * Persons with incomplete injury grades of ASIA C or D who can stand with support and who have some vol…
Interventions
- DeviceDeep Brain Stimulation (DBS)
The DBS system delivers electrical current into deep areas of the brain. In this study, the electrical current will be delivered continuously during the study duration to an area of the brain called the cuneiform nucleus (CnF). Stimulation frequencies are anticipated to be between 20 and 50 Hertz. Participants may choose to continue stimulation following study termination. This area of the brain is associated with the body's ability to start a movement.
- ProcedureDeep Brain Stimulation (DBS) Device Implant Procedure
Participants will undergo a one-time implantation of Cartesia DBS electrodes (bilateral) including the Vercise pulse generator in a single surgery (up to approximately 6 hours) to implant bilateral directional DBS leads in the cuneiform nucleus.
- OtherTraining Sessions
Training sessions occurs 3 times/week at the study center to condition the subjects before DBS implantation and after DBS implantation. Each session may last up to 60 minutes. Training sessions include joint mobility (passive stretching), volitional neuromuscular activation (active hip mobility), task isolation (weight shifting), task integration (stepping), and activity rehearsal (walking).
