Spinal Cord Injuries Clinical Trials

Between 39-67% of the 294,000 Americans who have a SCI suffer from long-term debilitating neuropathic pain, interfering with rehabilitation, general activity, mobility, mood, sleep, and quality of life. Pain can hinder any potential for functional improvement that could be obtained during rehabilitation. Yet, neuropathic pain is refractory to many treatments. Current interventions, such as medications and physical therapy, result in less than 50% reduction in pain for only about one third of the people trying them, calling for new treatment options. Qigong, a mind and body approach that incorporates gentle body movements, paired with a focus on breathing and body awareness to promote health and wellness, could reduce SCI-related neuropathic pain. If the hypothesis is supported, the resulting work could be transformative in demonstrating a potentially effective therapy for civilians, military Service members, and Veterans with SCI and neuropathic pain. The following provides the scientific basis for this hypothesis and establishes the rationale for this approach. This study also includes an optional, remote, quasi-experimental substudy, in which all participants will receive Qigong for 12 weeks, followed by 6 weeks followup. Read Less

Depression is more common after a spinal cord injury (SCI) than in the general population. Unfortunately, it is unknown how depression is typically treated in individuals with SCI or if commonly used treatment methods are effective. This study will investigate the safety and impact of a novel method for treating depression called repetitive transcranial magnetic stimulation (rTMS). rTMS is a type of non-invasive brain stimulation. Fourteen individuals with a cervical or thoracic level SCI and depression will complete an approved treatment plan using rTMS. Participants will be treated using rTMS five days a week for four weeks. After four weeks of treatment, the study team will review the safety of rTMS and assess changes in depressive symptoms. If the results are positive, larger studies can be designed to develop better treatment options for individuals with SCI and depression. Read Less

The investigators propose to understand the role of lumbosacral spinal cord epidural stimulation (scES) in recovery of autonomic nervous system function, voluntary movement, and standing in individuals with severe spinal cord injury (SCI). Thirty-six individuals with severe SCI who have cardiovascular and respiratory dysfunction and who are unable to voluntarily move the legs or stand will receive scES for cardiovascular function, voluntary movement, or standing with and/or without weight-bearing standing. Training will consist of practicing voluntary movements or standing in the presence of specific scES configurations designed for the voluntary movements of the legs and trunk (Vol-scES), or epidural stimulation configurations specific for standing (Stand-scES). Specific configurations epidural stimulation for cardiovascular function (CV-scES) will be provided during sitting and supine and during maneuvers of orthostatic or cardiovascular stress. The ability to move voluntarily, stand, as well as cardiovascular, respiratory, bladder, bowel and sexual function will be assessed in these individuals with chronic severe spinal cord injury. Quality of life and costs of health care also will be assessed. Read Less

Locomotor training (LT) facilitates recovery of spinal locomotor networks after incomplete spinal cord injury (ISCI), but walking impairments persist. A limitation of LT is insufficient excitation of spinal locomotor circuits to induce neuroplastic recovery. Transcutaneous spinal direct current stimulation (tsDCS) is a non-invasive approach to increase spinal excitation and modulate spinal reflexes. The study will examine if tsDCS combined with LT enhances locomotor rehabilitation after ISCI. Read Less

Individuals with spinal cord injury have heart attacks and strokes more frequently, and much earlier in life. People with spinal cord injuries develop plaque in vessels much faster, and the reasons why are unclear. Doctors generally attributed the increased risk with weight gain and developing diabetes, but many studies have shown that even without these common factors, plaque in vessels is developing more often and faster. Endothelial cells are a single layer of cells that line all vessels in the body and plays an important role in vessel health. Damage to endothelial cells is known to lead to heart attacks and strokes. Past studies on endothelial cells of people with spinal cord injury have been unclear. The investigators have new data that these cells are unhealthy after spinal cord injury a measurement. This includes measuring endothelial health by directly altering its function using a catheter in the arm and measuring small particles in blood called endothelial microvesicles. If the project is successful, the investigators will learn important information on the health of endothelial cells after spinal cord injury. The investigators will also be able to use these markers of endothelial cell function to create treatments to improve vessel health and prevent heart attacks and strokes later in life in people with spinal cord injury.

The purpose of this study is to determine if playing a virtual reality walking game can help improve neuropathic pain in adults with chronic spinal cord injury. Read Less

This study will assess how the serotonin precursor, 5-HTP, alter nervous system excitability and motor function in individuals with spinal cord injuries of differing chronicity and severity. Participants will visit the lab on 4 separate occasions where they will be administered four different drugs in a randomized, double-blinded, placebo-controlled crossover design. Read Less

The purpose of this study is to investigate the short-term effects of 3 approved FDA drugs (cyproheptadine (CPH), carbidopa-levodopa (CD-LD), and atomoxetine (ATX)) on motor responses when delivered in combination with hand training exercises in people with chronic spinal cord injury. The goal is to learn how to better strengthen connections between the brain and spinal cord after spinal cord injury, and if this connection is improved by one(or more) of the drugs. Multiple aspects of nerve transmission and muscle response will be measured via noninvasive brain and spinal cord stimulation, along with motor performance (dexterity and strength). Read Less

The goal of this clinical trial is to examine usability of a locally built adaptive rower for people with spinal cord injury using an established and tested design. The main questions it aims to answer are: 1. What exercise intensity of activity do users achieve on the rower for steady state and interval rowing plans? 2. What assistance is required for setup and usage of the adaptive rower? 3. What do users think about the ease of use and what is their satisfaction with the adaptive rower? Participants will complete a one-time exercise session with two adaptive rower bouts (10-15 minutes each) with a rest period in between. Read Less

Mild intermittent hypoxia (IH) initiates sustained increases in chest wall and upper airway muscle activity in humans. This sustained increase is a form of respiratory plasticity known as long-term facilitation (LTF). Repeated daily exposure to mild IH that leads to the initiation of LTF of upper airway muscle activity could lead to increased stability of the upper airway. In line with PI's laboratory's mandate to develop innovative therapies to treat sleep apnea, this increased stability could ultimately reduce the continuous positive airway pressure (CPAP) required to treat obstructive sleep apnea (OSA) and improve compliance with this gold standard treatment. Improved compliance could ultimately serve to mitigate those comorbidities linked to sleep apnea. Moreover, in addition to improving CPAP compliance numerous studies indicate that mild IH has many direct beneficial effects on cardiovascular, neurocognitive and metabolic function. Thus, mild IH could serve as a multipronged therapeutic approach to treat sleep apnea. In accordance with this postulation, our proposal will determine if repeated daily exposure to mild IH serves as an adjunct therapy coupled with CPAP to mitigate associated co-morbidities via its direct effects on a variety of cardiovascular, metabolic and neurocognitive measures and indirectly by improving CPAP compliance. Modifications in autonomic (i.e. sympathetic nervous system activity) and cardiovascular (i.e. blood pressure) function will be the primary outcome measures coupled to secondary measures of metabolic and neurocognitive outcomes.

People with spinal cord injuries may experience muscle tightness or uncontrollable spasms. This study is being conducted to investigate whether transcutaneous spinal stimulation can improve these symptoms. Transcutaneous spinal stimulation is a non-surgical intervention by applying electrical currents using skin electrodes over the lower back and belly. The investigators want to see how well the intervention of transcutaneous spinal stimulation performs by testing different levels of stimulation pulse rates. Also, transcutaneous spinal stimulation is compared to muscle relaxants such as baclofen and tizanidine, commonly given to people with spinal cord injuries, to reduce muscle stiffness and spasms. By doing this, the investigators hope to discover if transcutaneous spinal stimulation similarly reduces muscle spasms and stiffness or if combining both methods works best. This could help improve treatment options for people with spinal cord injuries in the future. Read Less

Children who suffer a spinal cord injury in the neck region have difficulty using their hands due to paralysis and/or weakness of their arms and hand muscles. The purpose of this project is to test the safety, comfort, and practicality of a new therapy that stimulates the spinal cord to facilitate activation of arm and hand muscles while practicing grasping, pinching, and reaching movements. The long-term goal is to provide better therapies that will improve the ability of children with SCI to more successfully play and accomplish everyday tasks using their arms and hands, similar to before their injury.
