Active clinical trials for "Spinal Cord Injuries"

This trial will investigate the safety and utility of spinal cord neuromodulation to improve urinary bladder function in the context of spinal cord injury.

The recent introduction of robotics for locomotor training in paraplegic patients, and in particular the use of anthropomorphic exoskeletons, has opened new frontiers in rehabilitation. Existing literature, though encouraging, is still scarce and studies demonstrating efficacy are highly heterogeneous and have a small sample size. Evidence is also needed about cortical plasticity after SCI, in conjunction with the use of innovative rehabilitation devices, through indicators like neurophysiological and neuroradiological markers, as the knowledge of such mechanisms is crucial to improve clinical outcomes. Cortical circuits controlling prosthetic devices are different from those controlling normal parts of the body and remodeling mechanisms following prosthetic use have been documented, but in conditions other than SCI. The aims of this randomized controlled trial, with a 2-arm parallel-group design, are: to evaluate and quantify the efficacy of locomotor rehabilitation with a robotic anthropomorphic exoskeleton (EKSO-GT) in terms of clinical and functional outcomes, and the persistence of such efficacy; to investigate the presence and persistence of brain neuronal plasticity and cortical remodeling mechanisms underlying the robotic rehabilitation approach. Fifty patients will be recruited and randomly assigned to 2 treatment arms. Both groups will follow a program of standard locomotor rehabilitation for 8 weeks. One group will also undergo an overground locomotor training with the EKSO-GT during the first 4 weeks.

Spinal cord injuries are anatomically mostly incomplete, showing tissue bridges of the spinal cord at the injury site. Of the 60% functionally incomplete patients, about half face a life in the wheelchair. Besides conventional rehabilitation, no prominsing further treatment options exist. One of the most plastic systems involved in locomotion is the pontomedullary reticulospinal tract, which is the oldest locomotor command system existing in most vertebrates, including primates. Muscle activation patterns for limb movements are programmed in the spinal cord and have to be activated and coordinated through commands from the so called mesencephalic locomotor region (MLR). The MLR consists of nerve cells in the lower mesencephalic tegmentum sending uni- and bilateral signals through the medullary reticulospinal tracts. Classical physiological studies showed that electrical stimulation of the MLR induce locomotion. For the first time this approach was transferred and recently published in a model of induced incomplete spinal cord injury by the Schwab group. Rats severly impaired in motor hindlimb control with only 10-20% spared white matter, recovered with fully functional weight bearing locomotion under MLR deep brain stimulation (DBS). Even rats with only 2-10% spared white matter regained weight supporting stepping. DBS is a clinical standard treatment option in patients with movement disorders but does not relieve all symptoms. Therefore, small studies of MLR stimulations have been safely used in Parkinsonian patients showing freezing of gait and frequent falls with variable results. In a translational approach, we aim at performing a multidisciplinary phase one clinical trial with 5 patients and incomplete spinal cord injury. With the means of our established universitary setup for DBS treatments the operations will be performed unilaterally under local anaesthesia in the Division of Neurosurgery, USZ, with perioperative electrophysiological recordings, clinical assessments and gait analysis under test stimulation in the Spinal Cord Injury Center Balgrist.

This study aims to improve continence and voiding of patients with spinal cord injury using electrical stimulation. The Finetech Vocare Bladder System is an implantable sacral nerve stimulator for improving bladder and bowel function in patients with spinal cord injury (SCI). It has been commercially available in Britain and other countries since 1982, and has been used in thousands of patients with SCI to improve bladder, bowel and sexual function. It received FDA approval in 1998 under Humanitarian Device Exemption H980005 and H980008 for providing urination on demand and to aid in bowel evacuation. Electrical stimulation to produce bladder contraction and improve bladder voiding after spinal cord injury has usually been combined with cutting of sensory nerves to reduce reflex contraction of the bladder, which improves continence. However, cutting these nerves has undesirable side effects. This study will not cut any sensory nerve. This study is testing the use of the stimulator for inhibiting bladder contraction by stimulating sensory nerves to improve continence after spinal cord injury, and for blocking sphincter contraction to improve voiding.

The overall objective of this project is to investigate the effectiveness of daily acute intermittent hypoxia therapy (dAIH), coupled with massed practice training, to improve upper-extremity function in individuals with chronic incomplete cervical SCI.

The goal of this study is to assess the function of the lungs and the muscles are used to breathe after individuals receive respiratory training, spinal cord stimulation, a combination of respiratory training and stimulation, a combination of arm training and stimulation, or a combination of trunk training and stimulation. The respiratory, arm, and trunk training combined with the spinal stimulation interventions are being used to activate the spinal cord below the level of injury. Investigators will be looking for changes in the function of the lungs and trunk muscles before, during, and after these task-specific and non-task-specific interventions for breathing to determine which one has the greatest effect. The results of this study may aid in the development of treatments to help individuals with spinal cord injuries that have impaired lung, arm, and trunk function.

The purpose of this experimental therapy is to evaluate the safety and efficacy of transplantation of autologous olfactory ensheathing cells (OECs) and olfactory nerve fibroblasts (ONFs) obtained from the olfactory bulb with simultaneous reconstruction of the posttraumatic spinal cord gap with peripheral nerve grafts, in patients with chronic complete spinal cord injury. The treatment will be performed in two patients that have sustained an anatomically complete spinal cord transection between the spinal cord segments C5 and Th10. All patients wanting to participate in this study have to send their application at the address: walk-again-project.org

This is a single blind, sham controlled crossover trial that will evaluate the effectiveness of acute intermittent hypoxia therapy (AIH) combined with transcutaneous (non-invasive) spinal cord stimulation on gait and balance function for individuals after spinal cord injury.

The aim of the project is to test the effectiveness of robot-assisted upper-limb exercise in persons after cervical spinal cord injury. In a randomised controlled two-arm trial, the effect of adding two types of robot-assisted upper-limb exercise to standard occupational therapy will be tested. Three primary and two secondary outcomes will be assessed using well-established measures.

The purpose of this research study is to investigate the safety and potential therapeutic effects of autologous, culture-expanded, adipose derived mesenchymal stem cell intrathecal injections in the treatment of spinal cord injury.
