This study looks at how the heart and blood vessels work after a spinal cord injury. It focuses on how a treatment called spinal stimulation affects blood pressure. Spinal stimulation is a way to send small electrical signals through the skin to see if it can help the heart and blood vessels work better. The study will take place at the Kessler Institute and will last for about a year. During this time, participants will have 20-29 sessions where doctors will measure things like blood pressure and heart function. They will also see how these things change over time.

• The study lasts about a year and includes 20-29 visits.
• Participants are people with a spinal cord injury that happened 7-50 days ago.
• People with heart devices or on certain medications cannot join.
