Active clinical trials for "Spinal Cord Injuries"

Spinal cord injury (SCI) results in damage to the descending neural pathways and leads to the immediate dysfunction of multiple physiological systems below the level of injury. Like adults, children with SCI suffer from neuromuscular paralysis which results in the inability to sit, stand, and walk. Current therapeutic interventions largely aim to compensate for paralysis to achieve mobility based on the assumption that damage to the central nervous system is permanent and irreversible, e.g. use of braces, standers, and wheelchairs. The objective of this proposal is to investigate the use of transcutaneous spinal stimulation (TcStim) to enable stepping in children with chronic SCI. The investigators will recruit 8 participants, ages 4-12 years with chronic, acquired SCI, T10 and above and non-ambulatory. The aims of this proposal are to 1) investigate the mechanisms of locomotor-specific regulation in the spinal neural circuitry of children with acquired SCI using single vs. multi-site TcStim, 2) investigate the capacity of the lumbosacral spinal cord for integration of task-specific input (e.g. load, speed) during facilitated stepping with and without TcStim, and 3) investigate the training effects of TcStim on the ability to step. Outcomes will provide a necessary initial step in the translation of scientific findings for neuromodulation from adults with SCI to children.

This is a randomized clinical controlled trial (RCT) to investigate the impact of a personalized nutritional intervention on functional and clinical outcomes the first year after traumatic spinal cord injury. The long term goal is to prevent gain of body fat mass and obesity.

Over the past ten years, the Cardiovascular Research Laboratory at Spaulding has refined a unique form of exercise for those with spinal cord injuries (SCI). Functional Electrical Stimulation Row Training (FESRT) couples volitional arm and electrically controlled leg exercise, resulting in the benefits of large muscle mass exercise. However, despite the potential for enhancing aerobic capacity by training the denervated leg skeletal muscle via hybrid FES exercise, the inability to increase ventilation beyond limits set by high level SCI restricts aerobic capacity. This research study will investigate two potential methods of improving ventilation in those with high-level SCI through a double-blind randomized trial. One method is non-invasive ventilation (NIV), which is an external breathing support machine. The second method is the use of Buspar, a drug, which has been used to treat respiratory dysfunction after SCI in rats and some human case reports. In this study, participants will engage in a 6-month FES row training program while receiving either NIV or shamNIV and Buspar or placebo, and under study tests to evaluate cardiopulmonary health and fitness.

A common therapeutic intervention after spinal cord injury (SCI) is prolonged standing in a standing frame. For people with SCI, standing for 40 minutes or more, three to four times weekly improves several health-related issues including well-being, circulation, skin integrity, reflex activity, bowel and bladder function, digestion, sleep, pain, and fatigue. However, a person who experiences orthostatic hypotension (OH)-defined as a decrease of 20mm hg in systolic blood pressure or a decrease of 10mm hg in diastolic pressure within 3 minutes of standing from a sitting or supine position-secondary to SCI may not tolerate positioning in a standing frame, thus resulting in a loss of access to these health benefits. OH is common for people with SCI. It results from central nervous system dysregulation causing pooling of blood in the lower extremities that can lead to dizziness, light-headedness, blurred vision, weakness, fatigue, nausea, palpitations, headache, and/or syncope. Although an array of physical and pharmacologic interventions are available to people in the general population for managing OH, few such interventions have been evaluated for use by people with SCI, especially when the level of injury is C5 or above. One possible intervention that may be effective for people with OH secondary to SCI is functional electrical stimulation (FES) because its application results in a dose-dependent increase in blood pressure. An unanswered question is whether the placement of FES electrodes on various parts of the body has differential effects. Therefore, the purpose of this study is to evaluate blood pressure responses among people with OH secondary to cervical SCI when receiving FES intervention involving the placement of electrodes in three different positions as well as when receiving no FES intervention during tilt table sessions. The selected positions for electrode placement are: (a) the calves, (b) the quads and abdominals, and (c) the quads, abdominals, and calves. The researchers hypothesize that FES intervention, regardless of placement, will result in better control of OH than no FES intervention and that no significant blood pressure difference will occur across the three FES placements.

In a current first-in-human study, called Stimulation Movement Overground (STIMO, NCT02936453), Epidural Electrical Stimulation (EES) of the spinal cord is applied to enable individuals with chronic severe spinal cord injury (SCI) to complete intensive locomotor neurorehabilitation training. In this clinical feasibility study, it was demonstrated that EES results in an immediate enhancement of walking function, and that when applied repeatedly as part of a neurorehabilitation program, EES can improve leg motor control and trigger neurological recovery in individuals with severe SCI to a certain extent (Wagner et al. 2018). Preclinical studies showed that linking brain activity to the onset and modulation of spinal cord stimulation protocols not only improves the usability of the stimulation, but also augments neurological recovery. Indeed, rats rapidly learned to modulate their cortical activity in order to adjust the amplitude of spinal cord stimulation protocols. This brain-spine interface allowed them to increase the amplitude of the movement of their otherwise paralyzed legs to climb up a staircase (Bonizzato et al. 2018). Moreover, gait rehabilitation enabled by this brain-spine interface (BSI) augmented plasticity and neurological recovery. When EES was correlated with cortical neuron activity during training, rats showed better recovery than when training was only supported by continuous stimulation (Bonizzato et al. 2018). This concept of brain spine-interface was validated in non-human primates (Capogrosso et al. 2016). Clinatec (Grenoble, France) has developed a fully implantable electrocorticogram (ECoG) recording device with a 64-channel epidural electrode array capable of recording electrical signals from the motor cortex for an extended period of time and with a high signal to noise ratio the electrical signals from the motor cortex. This ECoG-based system allowed tetraplegic patients to control an exoskeleton (ClinicalTrials.gov, NCT02550522) with up to 8 degrees of freedom for the upper limb control (Benabid et al. 2019). This device was implanted in 2 individuals so far; one of them has been using this system both at the hospital and at home for more than 3 years. We hypothesize that ECoG-controlled EES in individuals with SCI will establish a direct bridge between the patient's motor intention and the spinal cord below the lesion, which will not only improve or restore voluntary control of leg movements, but will also boost neuroplasticity and neurological recovery when combined with neurorehabilitation.

Treatment for sublesional bone loss (osteoporosis) in persons with chronic, motor-complete spinal cord injury (SCI) has been limited and unsuccessful to date. Romosozumab, a sclerostin antagonist, has potential to increase bone formation (anabolic) and decrease bone resorption (anti-catabolic) in persons with chronic SCI. Conventional anti-resorptive therapy alone would not be anticipated to reverse sublesional bone loss in a timely manner because the skeleton below the level of lesion in chronic SCI is assumed to be in a low turnover state. However, because there is a high likelihood that the bone accrued while on romosozumab will be lost once discontinued, denosumab, an anti-resorptive agent, will be administered after treatment with romosozumab, to maintain or, possibly, to continue to increase, bone mineral density (BMD). The purpose of this study is to address the gap in the treatment of osteoporosis in individuals with chronic SCI by partially restoring BMD with romosozumab treatment for 12 months and then to maintain, or further increase, BMD with denosumab treatment for 12 months. A two group, randomized, double-blind, placebo-controlled clinical trial will be conducted in 39 participants who have chronic (>3 years), motor-complete or incomplete SCI and areal BMD (aBMD) values at the distal femur of at the distal femur <1.0 g/cm2 measured by dual photon X-ray absorptiometry (DXA). The intervention group will receive 12 months of romosozumab followed by 12 months of denosumab, and the control group will receive 12 months of placebo followed by 12 months denosumab.

The investigators have recently shown in incomplete SCI patients that long-term paired associative stimulation is capable of restoring voluntary control over some paralyzed muscles and enhancing motor output in the weak muscles. In this study, the investigators will administer long-term paired associative stimulation to patients with incomplete cervical level SCI at the subacute stage, and investigate its effectiveness for upper extremity rehabilitation.

The overall purpose of this study is to test the efficacy of multi-modal training combining activity-based locomotor training and transcutaneous spinal stimulation (ABLT+scTS) to improve sitting posture and trunk control in children with a chronic spinal cord injury. The investigators will recruit 12 participants, ages 3-12 with chronic, acquired SCI, T10 and above and non-ambulatory. The participants in this study will be novices to scTS and AB-LT.

The aim of the study is to investigate the effects of 6 weeks of technological-assisted rehabilitation on function of upper extremity and hand in subjects with incomplete cervical spinal cord injury.

Physical activity is important to maintain health, fitness, and function in people with spinal cord injury (SCI) and social support is one of the most effective ways to increase physical activity participation. However, a large proportion of people with SCI are physically inactive and do not engage in recreational activities due to environmental and physical challenges. Many people with SCI also experience challenges with social connection, which may make engaging in physical activities more difficult. The investigators are offering a new online application designed specifically for people with SCI. The purpose of the research is to develop and evaluate a new online app, called SCI-Lynx, that would allow people with SCI to connect with other people and support each other in their physical activity, exercise, or other health or personal goals over a one-month period. This research will also evaluate how SCI-Lynx affects self-efficacy and social support for exercise and provide new information on changing physical activity participation and social connection in people with SCI.
