About this study

Official title: Assessing Cardiovascular Effects: Is There a Time Too Early for Spinal Stimulation in Acute SCI? A Year-Long Evaluation of Autonomic Function Following Injury

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.

Read the detailed description

This clinical study investigates the cardiovascular effects of spinal cord transcutaneous stimulation (scTS) in individuals with recent spinal cord injury (SCI), examining how blood pressure response to stimulation evolves over the first year post-injury. The primary objectives are to determine the optimal timing for initiating scTS for cardiovascular control, characterize blood pressure response evolution to stimulation over one year, and assess autonomic activation patterns through multiple testing methods.

The study will recruit five individuals with recent SCI, specifically targeting those who are 50 days or less post-injury, with an injury level at or above T6, and classified as American Spinal Injury Association Impairment Scale (AIS) A/B. All participants must present with low blood pressure and orthostatic hypotension and be between 18-75 years of age.

The study protocol is divided into inpatient and outpatient phases. During the inpatient phase, consisting of 5-11 sessions, participants undergo a basic assessment including autonomic dysfunction questionnaires, 24-hour blood pressure monitoring, cold pressor testing, and tilt tests with and without stimulation. The protocol also includes 2-3 days of stimulation mapping.

The outpatient phase spans 15-18 sessions over the remainder of the year. Participants undergo monthly mapping sessions and autonomic dysfunction assessments, with comprehensive autonomic testing conducted at 6, 9, and 12 months post-injury. Throughout both phases, researchers perform stimulation mapping across various spinal segments (thoracic, lumbosacral) using a 5-channel electrical stimulator, while monitoring blood pressure and electromyography to target a blood pressure range of 110-120 mmHg.

The study employs multiple assessment tools, including 70° tilt tests with orthostatic symptom evaluation every 5 minutes, cold pressor tests, autonomic dysfunction questionnaires, and 24-hour ambulatory blood pressure monitoring.

The study aims to track primary outcomes including blood pressure response to stimulation at different time points, evolution of orthostatic hypotension symptoms and management, and the pattern of autonomic dysfunction development post-injury.

A spin-off study is conducted to determine which cold-pressor intervention yields the most stable and consistent blood pressure response. This supplementary study compares 5 individuals with chronic SCI and 5 able-bodied controls. The findings from this spin-off study will directly inform the intervention protocol used in the main study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • spinal cord transcutaneous stimulationDevice

    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).
  • Ice testingProcedure or surgery

    Ice testing is performed using either a 3-minute ice-water immersion or a 3-minute ice-wrap application surrounding the foot. Each participant undergoes both the ice-water and ice-wrap conditions within the same session, separated by a 30-minute interval to allow the foot to return to baseline. Testing is conducted in both the seated and supine positions across two separate sessions, with both the cooling modality and body position randomized.

Study groups in NCT06841198
Study groupRoleWhat they receive
Testing position and cooling modality for the ice testOtherAs a spin-off of the main study, we aim to determine which cooling modality and body position elicit the most consistent and stable blood pressure response. To do so, we conduct a supplementary experiment involving 5 individuals with chronic SCI and 5 able-bodied controls. Each participant completes two experimental sessions: one in the supine position and one in the seated position. Within each session, participants undergo two tests, separated by a 30-minute rest period: 1. an ice-water immersion test, in which the foot is submerged in ice water for 3 minutes, and 2. an ice-wrap test, in which ice packs are applied around the foot and ankle for 3 minutes. The order of body position and cooling modality is pseudo-randomized. Throughout each test, blood pressure is continuously recorded, and participants rate discomfort or pain at 1-minute intervals.

Main study: assessing the BP changes throughout the first year post SCIOtherThe main study recruits 5 individuals with sub-acute SCI and follows them for one year to evaluate how blood pressure responses evolve during the early post-injury period.
Receives: Device: spinal cord transcutaneous stimulation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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)

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

  2. 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.

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

Secondary outcomes (3)
  1. cold pressor test

    In a traditional cold pressor test, the foot is immersed in 0°C ice water, indirectly assessing the degree of sympathetic activation through BP and HR

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

  2. 24-hour ambulatory blood pressure monitoring

    Parameters are recorded automatically every 15 min during the day and every 60 min at night. Participants will be asked to take notes regarding BP-related symptoms, activities, and their time points.

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

  3. An autonomic dysfunction following spinal cord injury questionnaire

    Assessing the severity and frequency of daily AD and OH episodes and their effect on daily activities

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