Study summary

The purpose of this study is to learn whether stimulation applied to the spinal cord through the skin (called transcutaneous spinal stimulation) can help control blood pressure in people with a spinal cord injury.

The main questions this study attempts to solve:

  1. What are the immediate effects of spinal cord transcutaneous stimulation on BP?
  2. Does stimulation produce lasting improvements in BP regulation and subsequently, daily function?
Read the detailed description

We want to find out if this stimulation can help both right away (during a session) and over time (after several sessions). Specifically, this study will look at whether spinal stimulation can treat orthostatic hypotension, which is a drop in blood pressure that happens when the patient moves from lying down to sitting or standing up. To take part, one must have had a spinal cord injury for more than one year.

Study arms

  • Experimental
    participants with chronic SCIs.

    Participation in this study will take about 5 to 6 months and will include approximately 30 to 40 separate lab visits. Most visits will last about 2 hours, though some of the early visits may take longer. The study consists of: 1. Baseline assessments, including a tilt test and various cardiovascular assessments 2. Mapping stimulation sessions - several days when different stimulation parameters and locations are tested in order to obtain the configurations for the most suitable blood pressure response. 3. Repeat tilt test, with stimulation (intervention 1), with continuous blood pressure monitoring 4. 20 stimulation sessions, each 30-min long, with participants in their wheelchairs (intervention 2) 5. Repeat baseline assessments

    Device: Tilt test with stimulation (real-time effects): Intervention 1 · Device: 20 sessions of stimulation (Intervention 2)

Interventions

  • DeviceTilt test with stimulation (real-time effects): Intervention 1

    While lying supine, participants will be strapped to a Hi-Low tilt-table bed. The bed will gradually be tilted to a 70 degrees tilt, during which time continuous hemodynamic measures will be recorded. This position will be maintained for 30 minutes. During tilt, transcutaneous stimulation will be applied, using the configuration that was chosen based on the mapping sessions.

  • Device20 sessions of stimulation (Intervention 2)

    Participants will undergo 20 separate 30-minute sessions of transcutaneous spinal cord stimulation while seated in their wheelchairs

What researchers measure

Primary outcomes

  1. Systolic blood pressure

    Evaluate changes in blood pressure during an orthostatic tilt test comparing stimulation to no stimulation.

    Time frame: 1 month

  2. Systolic blood pressure

    changes in blood pressure drop with tilt (no stimulation) from baseline testing to tilt test (no stimulation) after 20 sessions of stimulation

    Time frame: Through study completion, an average of 5 months

Secondary outcomes

  1. duration in tilt test

    how long the participant was able to stay in an orthostatic provocation (70 degrees tilt in tilt table)

    Time frame: Through study completion, an average of 5 months

  2. Orthostatic symptoms questionnaire

    A designated questionnaire evaluates symptoms such as headaches, dizziness, blurred vision, nausea, weakness, confusion, fatigue, ringing in the ears, and feeling of passing out. Recorded every 5 minutes (or sooner if symptoms worsen). Participants rate each symptom on a scale of 0 to 10, with 10 indicating the highest severity.

    Time frame: Through study completion, an average of 5 months

  3. 24-hour ABPM OH events - taken at home

    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. Conducted before, halfway through, and after the intervention

    Time frame: Through study completion, an average of 5 months

  4. Autonomic Dysfunction Following Spinal Cord Injury questionnaire scores

    24-item self-reported tool designed for clinical practice and research to assess symptoms of BP instability. It evaluates the frequency and severity of symptoms during high and low BP events

    Time frame: Through study completion, an average of 5 months

  5. Spinal cord injury - quality of life scores

    A questionnaire was developed to address the shortage of psychometrically sound and relevant patient-reported outcome measures for clinical care and research in SCI rehabilitation

    Time frame: Through study completion, an average of 5 months

  6. Canadian Occupational Performance Measure scores

    A semi-structure interview where the individual identifies and measures their areas of difficulty, scoring their performance on the tasks and their satisfaction with their ability

    Time frame: Through study completion, an average of 5 months
