Transcutaneous Spinal Cord Stimulation to Promote Walking Recovery After Spinal Cord Injury
- Conditions
- Spinal Cord Injuries
- Interventions
- Device: Exo + TSCSDevice: Exo + Sham
- Registration Number
- NCT05982171
- Lead Sponsor
- Craig Hospital
- Brief Summary
The goal of this clinical trial is to investigate the effects of transcutaneous spinal cord stimulation (TSCS) combined with exoskeleton training, as compared to exoskeleton training alone to improve motor function in individuals with incomplete spinal cord injury who are 12 months or less post-injury. Participants will be randomly assigned to a treatment group (exoskeleton training with TSCS, or exoskeleton training without TSCS). Participants in both groups will undergo a baseline evaluation, then take part in 24, 1-hour training sessions at Craig Hospital. After the 24 sessions have concluded, participants will undergo a post-treatment evaluation as well as a follow-up evaluation four weeks after training is completed. Researchers will compare the two groups by evaluating the following areas:
* walking ability and speed
* lower extremity strength, activation, and spasticity
* trunk control
* bowel and bladder function

Group Intervention Description Exoskeleton+Transcutaneous Spinal Cord Stimulation Exo + TSCS Treatment in this group will involve walking overground using the assistance of an exoskeleton while receiving a therapeutic level of transcutaneous spinal cord stimulation (TSCS) thoracolumbar spinal cord areas. Focus will be on stepping at a high intensity throughout the session as measured by heart rate. Exoskeleton+Sham Stimluation Exo + Sham Treatment in this group will involve walking overground using the assistance of an exoskeleton while receiving a non-therapeutic level of stimulation (considered to be a sham). Focus will be on stepping at a high intensity throughout the session as measured by heart rate.
- Primary Outcome Measures
Name Time Method Change in score on Walking Index for SCI (WISCI) II Baseline to Immediately After Intervention Assesses the amount of physical assistance/devices needed for walking following paralysis from SCI (scale of 0-20 with higher score indicating less need for assistance)
- Secondary Outcome Measures
Name Time Method Change in lower extremity strength as measured by Lower Extremity Motor Score (LEMS) Baseline to Post-treatment Assesses strength in 10 lower extremity muscle groups (each muscle scored 0-5 with higher score for greater strength; total score ranges 0-50.
Change in balance/trunk control as measure by the Function in Sitting Test Spinal Cord Injury Baseline to Immediately After Intervention Assesses static, proactive, and reactive balance as well as sensory integration. Each area assessed on scale of 0-4 with higher score indicating more independent trunk control.
Change in bladder function as measured by Neurogenic Bladder Symptom Scale Baseline to Immediately After Intervention Symptom based questionnaire evaluating bladder function and its impact on quality of lifehe Neurogenic Bladder Symptom Score (NBSS) is a validated 24 item questionnaire that measures bladder symptoms across 3 different domains: incontinence (scored 0-29), storage and voiding (scored 0-22), and consequences (scored 0-23); there is a single general urinary QOL question scored from 0 (pleased) to 4 (unhappy
Change in distance walked as measured by the 6 Meter Walk Test Baseline to Immediately After Intervention Measures distance walked (in meters) over 6 minute time period
Change in spasm frequency and severity as measured by Penn Spasm Frequency Baseline to Immediately After Intervention Self-report measure of perception of spasticity frequency (0 to 5 scale with higher score more frequent spasms) and severity (1-3 scale with higher score more severe spasms)
Change in bowel function as measured by Neurogenic Bowel Dysfunction Scale Baseline to Immediately After Intervention Symptom based questionnaire evaluating bowel dysfuntion and its impact on quality of life (score 0-47 with higher score indicating greater bowel dysfunction)
Change in walking speed as measured by the 10 Meter Walk Test Baseline to Immediately After Intervention Participants walk a ten-meter track; time to walk the middle six meters is recorded and converted to meters/second (speed)
