Combination Therapy to Improve SCI Recovery.

Participants walk ten meters without assistance at their fastest, but safest speed with a minimum of 1-minute of rest between two trials. Average speed across the up to three 10MWT trials will be used for analysis. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

Participants walk ten meters without assistance at their fastest, but safest speed with a minimum of 1-minute of rest between two trials. Average speed across the up to three 10MWT trials will be used for analysis. Rate of change is the number of treatment sessions required to achieve an increase in 10MWT speed of at least the minimal clinically important difference (0.06 m/s) as compared to pre-treatment baseline.

Participants perform the 6MWT at their fastest, most comfortable walking speed sustainable for 6 minutes. Distances will be recorded at 2 and 6 minutes. The test will be based upon the participant's ability to finish each assessment without human assistance. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

The TUG test is used to assess the dynamic balance of an individual. It measures the amount of time (recorded in seconds) it takes for the individual to rise from a standard arm chair, walk a distance of 3 meters and return to the initial position resting against the back of the chair. Participants will perform up to three trials of the TUG test. Average speed across TUG trials will be used for analysis. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

Participants will report their pain level using the Numeric Pain Rating Scale. The scale is from 0 to 10; 0 being no pain and 10 being extreme pain. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

The CVLT is a brief, individually administered battery to measure cognitive decline or improvement and assesses verbal learning and memory for older adolescents and adults. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

Participants will have their systolic and diastolic blood pressure measured. A systemic hypertensive event is quantified as a systolic pressure exceeding 140 mmHg and/or diastolic pressure exceeding 90 mmHg. A hypertension incident rate is the number of hypertensive events divided by the total person-time. Person-time is in units of person-measures (the sum of the total number of BP measurements) taken for each person. Person-measures accounts for the total number of chances for detecting a hypertensive event and accounts for measurements not made due to drop-out or a disqualifying adverse event.

The occurrence of autonomic dysreflexia will be assessed. An autonomic dysreflexia event will constitute a participant having a SBP increase from baseline of 20 mmHg not associated with exercise or systolic blood pressure (SBP) greater than 150 mmHg with complaints of headache, diaphoresis, and/or blurred vision and will be diagnosed by our study team clinicians. We will compute autonomic dysreflexia incident rate as the number of autonomic dysreflexia events divided by the total person-time. We define person-time in units of person-days (the number of days a person remains in the study). Person-days account for the total number of chances for detecting autonomic dysreflexia and accounts for days on which measurements were not made due to drop-out or a disqualifying adverse event.

The LEMS uses ASIA key muscles in both the lower extremities, with a total possible score of 50 (maximum score of 5 for each muscle group). Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

The study team will quantify the total lower extremity spasticity score using the cumulative sum of 3 SCATS subscales: clonus (0=no spasticity; 3=severe), flexor (0=no spasticity; 3=severe), and extensor (0=no spasticity; 3=severe). Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

This questionnaire is a symptom-based score for neurogenic bowel dysfunction. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

This questionnaire is a symptom-based score for neurogenic bladder dysfunction. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

The SCI-FAI assesses functional walking ability in ambulatory individuals with SCI. Component scores range from 0 to 20 in the gait parameter component, 0 to 14 in the assistive device component, and 0 to 5 in the walking mobility component. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.

The WISCI is used to assess the amount of physical assistance is needed as well as devices required for walking following paralysis. This assessment is from 0-20 with value corresponding to a physical assistance description. Change is the difference between the post-treatment assessment 2 and pre-treatment baseline.
