Brief Summary

The study aims to explore how cardiovascular function changes in the first year after a spinal cord injury, and to see how different treatments, like spinal stimulation through the skin (transcutaneous spinal stimulation), affect blood pressure. The main questions are: How does stimulation affect blood pressure over the year? What is the level of cardiovascular activation throughout the year? The study will start during the inpatient stay at the Kessler Institute for Rehabilitation and continue after discharge as an outpatient, totaling about 20-29 sessions over the year.

Conditions

Spinal Cord Injuries (SCI); Orthostatic Hypotension, Dysautonomic; Cardiovascular; Transcutaneous Spinal Stimulation

Keywords

Transcutaneous Spinal Cord Stimulation; spinal cord stimulation; orthostatic hypotension; blood pressure; cardiovascular; neuromodulation; acute spinal cord injury; chronic spinal cord injury; inpatient rehabilitation; tilt testing; cold pressor test; ambulatory blood pressure monitoring; autonomic dysfunction following spinal cord injury

Outcome Measures

Primary Outcomes (2)

• Systolic blood pressure in seated mapping sessions

  Spatiotemporal mapping sessions involving stimulation of various spinal segments, utilizing different parameters (e.g., frequency, waveform). A BP response in a mapping session will be defined by a significant increase in SBP of at least 20 mmHg with stimulation compared to baseline SBP (without stimulation)

  The procedure will be repeated throughout the year, starting shortly after the injury and occurring approximately once a month.

• systolic blood pressure in a 70 degree tilt

  In this study, tilt-tests are conducted in pairs: first, a standard tilt test (without stimulation), followed by a tilt test with stimulation aimed at preventing orthostatic hypotension. We will compare the drop in systolic blood pressure during the tilt test with stimulation to the drop observed in the standard tilt test.

  The procedure will be repeated throughout the year, starting shortly after the injury and occurring approximately every three months

Secondary Outcomes (3)

• cold pressor test

  The procedure will be repeated throughout the year, starting shortly after the injury and occurring approximately every three months

• 24-hour ambulatory blood pressure monitoring

  The procedure will be repeated throughout the year, starting shortly after the injury and occurring approximately once a month.

• An autonomic dysfunction following spinal cord injury questionnaire

  The procedure will be repeated throughout the year, starting shortly after the injury and occurring approximately once a month.

Interventions

spinal cord transcutaneous stimulation DEVICE

Stimulation, using the Neostim-5 (Cosyma Ltd.), a 5-channel electrical stimulator, will be administered throughout the study period, beginning shortly after the injury and continuing at regular intervals until one year post-spinal cord injury. It will be performed in two settings: 1. During seated mapping to identify stimulation sites (potentially T7/8, T11/12, L1/2, and S1/2) and determine stimulation parameters (e.g., frequency, pulse wave, amplitude) that elevate systolic blood pressure (SBP) and maintain it within the target range of 110-120 mmHg. 2. During 70-degree tilt tests to elicit an orthostatic response (a drop in blood pressure accompanied by symptoms).

Eligibility Criteria

• Age: 18 Years - 75 Years

You may qualify if:

• Individuals with a spinal cord injury undergoing inpatient rehabilitation at the Kessler Institute for Rehabilitation
• Between 18-75 years old
• days after injury
• Injury level ≥ T6 (a cervical or a high-level chest injury)
• Individuals experiencing low blood pressure after the injury

• Devices such as brain/spine/nerve stimulators, a cardiac pacemaker/defibrillator, or intra-cardiac lines are present in the body.
• There is a significant disease affecting the blood vessels or signals in the heart, or a recent heart attack (myocardial infarction) has occurred.
• A new medication has been prescribed to treat blood pressure or a heart problem within the last five days (excluding midodrine).
• There is a known infection in the body (e.g., urinary tract infection) or a current illness (e.g., recent diagnosis of deep vein thrombosis (DVT) or other blood clotting issues, and/or a pressure injury that might interfere with the study).
