- Brief Summary
The DOOR SCI project examines dosing effects of robotic gait training (RGT) and transcranial magnetic stimulation (TMS) initiated during inpatient rehabilitation and continued through early outpatient rehabilitation
- Detailed Description
Emerging evidence indicates that robotic exoskeleton use results in positive outcomes for those with chronic SCI, yet limited evidence exists for the acute setting. The potential benefit of RGT initiated during inpatient rehabilitation when recovery is greatest is unknown yet appears promising due to established principles of neuroplasticity and the fact that RGT incorporates the critical components of gait training. As a result of the lack of evidence, no clinical practice guidelines exist that delineate which gait retraining approach or dose during early phases of recovery results in the best outcomes for people with motor incomplete SCI. The DOOR SCI project examines dosing effects on 5 occasions over 9 months: (1) inpatient rehabilitation admission and (2) discharge, (3) after completing 24 RGT sessions, (4) 1-month post RGT, and (5) 9-months post SCI). To test the overarching goal, investigators propose three specific aims:
Aim 1: Using a randomized controlled trial, prospectively examine whether the dosing frequency \[24 sessions delivered as high, moderate, or low frequency, defined by number days/week (4, 3, or 2 days/week over 6, 8, 12 weeks)\] of RGT therapy provided during the acute/subacute recovery phase after motor incomplete SCI impacts outcomes compared to usual care only.
Aim 2: Investigate the difference over 9 months of the neuroplastic effect of RGT dosing as measured by single pulse TMS.
Aim 3: Evaluate the safety, tolerability, and feasibility of delivering different dosing frequencies of RGT from inpatient to outpatient rehabilitation settings.

- Primary Outcome Measures
Name Time Method Change in Walking Index for Spinal Cord Injury - II (WISCI-II) from baseline Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset The WISCI-II defines the physical limitation for gait secondary to impairment at the person level and indicates the ability of a person to walk after SCI. The WISC-II rank orders the ability a person to walk on a scale of 0-20 with 0 representing no ability to stand or participate in assisted walking and 20 representing an ability to walk 10 meters with no devices, no braces, and no physical assistance.
- Secondary Outcome Measures
Name Time Method Change in 10-Meter Walk Test (10MWT) Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset The 10MWT assesses gait speed (m/s) over a short duration.
Change in Spinal Cord Independence Measure (SCIM) Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset The SCIM assesses the ability of a person with spinal cord injury (SCI) to preform specified tasks independently, with assistance, or with assistive devices.
SCIM is composed of 19 items with total SCIM scores ranging from 0 (required assistance) to 100 (independence). A higher score means greater independence.Change in Numerical Pain Rating Scale (NPRS) Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset Pain is a significant problem in many individuals with SCI. A 0-10 Point Numerical Pain Rating Scale (NRS) is recommended as the outcome measure for pain intensity after SCI during acute and subacute phases. Pain severity can be categorized into 3 distinct groups as relates to pain interference: 1-3 (mild), 4-7 (moderate), 8-10 (severe). A higher score means greater pain severity.
Change in Fatigue Severity Scale (FSS) Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset The Fatigue Severity Scale (FSS) is used to measure fatigue in neurologic disorders and measures the effects of fatigue on function. It is measure on the following scale:
1. - Strongly Disagree
2. - Disagree
3. - Slightly Disagree
4. - Neutral
5. - Slightly Agree
6. - Agree
7. - Strongly Agree A higher score means greater fatigue.Change in Penn Spasm Frequency Scale (PSFS) Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset The PSFS is a self-report measure to assess a patient's perception of spasticity frequency and severity following a SCI. With excellent internal consistency (ICC = 0.90), the current version was modified from the original to include both frequency and severity. A higher score means greater magnitude in spasms.
Change in Patient Health Questionnaire - 9 (PHQ-9) Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset The PHQ-9 is a self-report measure to assess the presence of depressive symptoms. Each items is scored on the following scale:
0 - not at all
1. - several days
2. - more than half the days
3. - nearly daily
Total scores are calculated by adding all the score and provides a possible depression severity score:
none (0-4), mild (5-9), moderate (10-14), moderately severe (15-19), and severe (20-27). A higher score means greater severity in depressive symptoms.Change in Life Satisfaction Questionnaire (LISAT) Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset The LISAT is a nine-item quality of life questionnaire suitable for SCI populations containing a single item assessing overall life satisfaction, along with eight additional domain-specific items. Items are answered on a 6-point likert scale that ranges from 1 (very dissatisfied), to 6 (very satisfied). The total Life Satisfaction score is computed as the mean of the item scores and the results are divided into dissatisfied (1-4) and satisfied (5-6). A higher score score means greater life satisfaction.
Change in Physical Activity by GT9x Actigraph accelerometer Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset Active energy expenditure will be measured in counts per day using a GT9x Actigraph accelerometer. Patient will be instructed to wear the watch on an unaffected wrist for one week. Higher counts represent greater physical activity.
Change in Neurophysiologic biomarkers by single pulse transcranial magnetic stimulation (TMS) Change in baseline, within 5 days of discharge, within 5 days post-intervention (RGT Groups) or 1-month post-discharge (UC group), 1-month post-intervention or 2-months post-discharge (UC group) (5) 9-months post-SCI onset Motor evoked potential (MEP) amplitudes will be measured and indexed from lower extremity muscle by single pulse transcranial magnetic stimulation (TMS).
