Motor & Autonomic Concomitant Health Improvements With Neuromodulation & Exercise Training: An SCI RCT
Sponsor: University of British Columbia
Summary
Spinal cord injury (SCI) disrupts many aspects of life, including the loss of volitional movement and involuntary control of bodily functions; both crucial functional recovery priorities for this population. Mobility impairments and secondary complications limit an individual's ability to exercise, a behavior known to have wide-ranging functional and health benefits. This trial will investigate whether activity-based therapy (ABT), using body-weight-supported treadmill training (BWSTT), can change the strength of signals from the brain that control volitional movement, leading to improvements in seated balance as well as other important involuntary bodily (i.e. cardiovascular, urinary tract, bowel and sexual) functions. The investigators aim to determine whether these improvements can be augmented with the addition of non-invasive transcutaneous spinal cord stimulation (TSCS). This therapy has been shown to re-awaken dormant spinal circuits. In this randomized controlled trial, TSCS with ABT, using BWSTT (three sessions/week for twelve weeks), will be compared to ABT+SHAM in individuals with chronic motor-complete spinal cord injury (SCI). Those in the ABT+SHAM group will be given the option to complete an ABT+TSCS open-label follow-up. Before and after training, the following outcomes will be assessed by validated methods: corticospinal excitability, motor function, and seated balance (Hypothesis 1 - Motor Function); severity and frequency of blood pressure instability, urinary tract, bowel, and sexual dysfunctions (Hypothesis 2 - Autonomic Functions); and general health (Hypothesis 3 - Quality of Life). This collaborative project is between consumers with SCI and clinicians/scientists with expertise in SCI care (kinesiologists, physiotherapists, physiatrists, sexual health clinicians). Compared to ABT alone, the investigators anticipate that ABT+TSCS will result in superior improvements in motor and autonomic functions in individuals with SCI.

Interventions
Transcutaneous Spinal Cord Stimulation
Therapeutic TSCS will be delivered during ABT using a non-invasive central nervous system stimulator (TESCoN, SpineX Inc., CA, USA). Stimulation will involve charge balanced monophasic rectangular waveforms with 1.0-ms pulses, administered at 30 Hz, with a carrier frequency of 10 kHz and a current ranging from 10 to 130 mA.
SHAM (low-intensity) Transcutaneous Spinal Cord Stimulation
Ineffective stimulation will be administered at the same anatomical location as therapeutic TSCS.
Activity-Based Therapy
Using BWSTT, all participants (both arms) will train 3 times per week for 12 weeks with a target to reach 45 minutes of gait training in each session. For gait training, the level of body weight support and speed of walking will be adjusted to allow the person to bear as much weight as possible while maintaining proper stance limb kinematics.
