Transformation of Paralysis to Stepping

Status Recruiting

Clinical Trial Summary

The main goal of the project is to develop multiple noninvasive neuromodulatory strategies to facilitate full weight bearing stepping overground in people with paralysis. We will determine the effectiveness of combining noninvasive spinal cord stimulation and the administration of buspirone (a monoaminergic agonist) in facilitating locomotor activity in a gravity-neutral apparatus, during body weight supported stepping on a treadmill, when stepping overground in an assistive robotic exoskeleton, or during full weight bearing stepping overground in a rolling walker. Our objective is to identify the experimental variables that define the efficacy of these novel neuromodulatory techniques over a 5 year period in 15 participants with severe spinal cord injury who are at least one year post-injury.

Clinical Trial Description

Aim 1: Define the relative effectiveness of transcutaneous electrical stimulation at multiple stimulation spinal sites and oral Buspirone in facilitating nonweight-bearing (gravity neutral device, GND) and weight-bearing (treadmill) stepping in individuals with chronic motor complete paralysis. Aim 1.1: Define the relative effectiveness of transcutaneous electrical stimulation at multiple spinal sites to facilitate non-weight-bearing (GND) and weight-bearing (treadmill) stepping in spinal cord injury subjects. Aim 1.2: Define the relative effectiveness of transcutaneous electrical stimulation at multiple spinal sites plus oral Buspirone to facilitate nonweight-bearing (gravity neutral device, GND) and weight-bearing (treadmill) stepping in spinal cord injury subjects. Aim 2: Determine the relative effectiveness of Ekso-technology combined with transcutaneous electrical stimulation and/or oral Buspirone in lowering the robotic assistance and enhancing the ability to step self-assisted in a rolling walker during over-ground stepping in individuals with a chronic, severe (AIS A/B) spinal injury. Aim 3: Determine the relative effectiveness of Ekso-technology combined with transcutaneous electrical stimulation and/or oral Buspirone in lowering the robotic assistance and enhancing the ability to step self-assisted in a rolling walker during over-ground stepping in individuals with motor incomplete (AIS C) paralysis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
