Interventions

  • Transcutaneous Spinal Cord Stimulation — DEVICE
    Non-invasive electrical stimulation of the spinal cord over the skin. A portable tSCS device, SCONE or TESCoN (SpineX Inc., USA), whichever available, will be used to deliver 1ms pulses with 10kHz carrier frequency at 30 Hz, which has demonstrated autonomic recovery in our previous studies. The location of tSCS is predetermined (at T10 and T11 vertebral levels). The stimulation intensity will range from 10 to 200 mA and specific criteria will be followed to determine the optimal therapeutic stimulation.
  • Sham Stimulation — DEVICE
    Non-invasive electrical stimulation of a lower extremity muscle group over the skin. A portable tSCS device, SCONE or TESCoN (SpineX Inc., USA), whichever available, will be used to deliver sham stimulation. The intensity of electrical stimulation will be briefly ramped up to a level at which the participants report perceiving the stimulation (i.e., sensory threshold), then ramped down and turned off for the remainder of the intervention.

Study Details

This study is a randomized, single-blind, two-arm sham-controlled clinical trial to evaluate the safety and efficacy of transcutaneous spinal cord stimulation (tSCS) over the lower thoracic and upper lumbar spinal cord segments for cardiovascular function in adults (21-65 years old) with cervical and upper thoracic spinal cord injury (SCI) (≥T6) AIS A-D during inpatient rehabilitation and outpatient visits within three months after the onset. We will recruit 26 individuals with SCI, admitted to inpatient rehabilitation facilities (IRFs) or after discharged from IRFs. We will also examine the effect of tSCS on lower urinary tract (LUT) and bowel functions as secondary outcomes. The main questions this study aims to answer are: 1. Assess the safety of single and repeated tSCS session(s) on cardiovascular function in the acute SCI: We will test the safety of single tSCS at T10-L2 session at rest and during orthostatic challenge (i.e., situ-up tests) at the baseline and the effect of five tSCS sessions on cardiovascular function in individuals with SCI ≥ T6. 2. Assess the effect of long-term tSCS on autonomic function in the subacute SCI phase: We will investigate the efficacy of long-term (total 18 sessions) tSCS on cardiovascular and pelvic organ functions. 3. Evaluate the sustained effect of tSCS on autonomic recovery six months after the onset of SCI: We will assess the sustained effect of repeated tSCS sessions (18 sessions) on cardiovascular and pelvic organ functions at 6-month post-SCI. Participants will: * Receive either transcutaneous spinal cord stimulation or "sham" spinal cord stimulation while inpatient in the first 8 weeks (Part A). * Those willing and able to come after discharge or after the 8 weeks will be asked to come back and complete additional tSCS for a total of 18 weeks (Part B), with a follow-up period of 6 months. All participants will receive tSCS during this outpatient follow-up portion of the study. * During assessment visits the researchers will perform a variety of exams including a neurologic, cardiovascular, pulmonary, bladder and bowel, physical, and autonomic exam, and will ask questions about quality of life and functioning. Participants will be asked to complete a test of how well their bowels are functioning (colonic transit test) and an abdominal X-Ray. Researchers will compare those who receive tSCS to those who receive sham stimulation to see if tSCS is an effective treatment for improving the body's autonomic functioning following recent-onset SCI.

Arms

  • Experimental: Transcutaneous Spinal Cord Stimulation
    Device: Transcutaneous Spinal Stimulation Non-invasive electrical stimulation of the spinal cord over the skin. A portable tSCS device, SCONE or TESCoN (SpineX Inc., USA), whichever available, will be used to deliver 1ms pulses with 10kHz carrier frequency at 30 Hz, which has demonstrated autonomic recovery in our previous studies. The location of tSCS is predetermined (at T10 and T11 vertebral levels). The stimulation intensity will range from 10 to 200 mA
  • Sham Comparator: Sham stimulation
    Device: Sham Stimulation Non-invasive electrical stimulation of a lower extremity muscle group over the skin. The intensity of electrical stimulation will be briefly ramped up to a level at which the participants report perceiving the stimulation (i.e., sensory threshold), then ramped down and turned off for the remainder of the intervention.

Primary Outcome Measure

Change in systolic Blood Pressure (BP) [ Time Frame: Repeated measurements at baseline, post-intervention (at time of discharge from inpatient rehabilitation), and 6 months post-spinal cord injury; assessed at these 3 timepoints over 6 months. ]
