Robot Assisted Gait Training in Persons With a Spinal Cord Injury
SCI - Spinal Cord InjuryOver the past decade, RAGT has emerged as a promising method for improving ambulation after spinal cord injury (SCI). Early reports of this therapy were very promising, yet a recent study suggested that even though RAGT may improve locomotor ability in the acute SCI population, it appears less functional to more conventional forms of ambulation such as wheelchair propulsion. What most of these studies have neglected to address, however, is the efficacy of RAGT as a therapeutic exercise intervention for the SCI population. Indeed, persons with SCI lead by definition a sedentary lifestyle. This reduced activity can lead to a variety of secondary health complications, including an increased risk for cardiovascular disease, spasticity, altered muscle composition and reduced joint range of motion (ROM), increased risk for pressure sores, reduced bone mineral density, increased risk for osteoporosis, and bladder and bowel dysfunction. In addition, psychological components such as body image, self-esteem, self-efficacy, psychological well-being and quality of life in general may be affected. Consequently, before RAGT is dismissed as an expensive but perhaps not superior alternative to conventional rehabilitation strategies after SCI, the potential effect of this therapy on a variety of health-related outcomes needs to be considered, and the potential physiological and psychological benefits associated with this whole-body upright exercise therapy may justify its use in both the acute and chronic SCI populations. Several investigations have already indicated that regular exposure to RAGT results in some very significant health-related benefits that may decrease the aforementioned risk of secondary health complications. To our knowledge however, longitudinal effect studies in the SCI population have not yet been conducted, and further studies are needed to provide definitive evidence. It can be assumed that such insights may further optimize long-term health benefits, but also the cost-benefit ratio of RAGT. In addition, a detailed analysis of RAGT parameters (walking time, crutch position, forward and lateral center of gravity shift, step length and height, swing phase, walking speed, etc.) and the direct cardiovascular response (heart frequency, blood pressure, blood lactate concentration) to RAGT have not yet been conducted. The purpose of this research project is therefore to investigate the longitudinal effect of RAGT on the psychological well-being (Quality of Life, pain, fatigue), independence in activities of daily living, muscular strength and joint range of motion (ROM), and bladder and bowel function in persons with SCI.
Neural Plasticity and Motor Recovery After Early and Intensive Upper Extremity Motor Training in...
Spinal Cord InjuriesAfter spinal cord injury (SCI), there is a disruption in neural circuits resulting in paralysis. There is not yet a cure for paralysis. In persons with Cervical SCI (pwC-SCI) recovery of arm-hand function is very important as it has a significant impact on the patients' level of independence and quality of life. Recovery is assumed to involve alterations in both central and peripheral motor systems. Motor training at an intensive dosage potentially provides a powerful stimulus for neurological recovery. This project exploits the peripheral and central neuroplastic effect of an early (<10 weeks after injury) and intensive (10 weeks of 12 hours in addition to usual care) upper limb motor training program (EIUMT) directed at recovery below the level of the injury in pwC-SCI within an international multi-center randomized controlled trial including 40 pwC-SCI. It has 4 objectives: to investigate 1)central neural plasticity by identifying alterations in cortical neuroplasticity and corticospinal excitability; 2)peripheral neural plasticity by identifying alteration in axonal excitability and number of motor units; 3)behavioral motor recovery of upper limb and 4)relationships between dose dimensions of motor intervention and behavioral and neurophysiological outcome measures aer EIUMT. Cutting-edge neurophysiological measures are used to provide insight in the mechanism of neuroplasticity after EIUMT and will be taken before and after EIUMT and at 6 months follow-up.
European Multicentre Study of Human Spinal Cord Injury
Spinal Cord InjuryToday there is accumulating evidence from animal experiments that regeneration can be induced after a spinal cord injury (SCI). Consequently in the near future, new therapeutic approaches to induce some regeneration will be included in the treatment of patients with SCI. The aim of this proposal is to provide the required clinical basis for the implementation of novel interventional therapies. The establishment of combined clinical, functional and neurophysiological measures for a qualitative and quantitative assessment of spinal cord function in patients with SCI at different stages during rehabilitation represents a basic requirement to monitor any significant effect of a new treatment. Therefore, several European Paraplegic Centres involved in the rehabilitation of acute traumatic SCI patients build up a close collaboration for standardised assessment. The aim is to get knowledge about the natural recovery after spinal cord lesion in a larger population of patients in the sense of a historical control group and to bring new standardised assessment tools to the clinical setting.

Spinal Cord Stimulation for Respiratory Rehabilitation in Patients With Chronic Spinal Cord Injury...
Spinal Cord InjuriesRespiration DisordersRespiratory complications are among the leading causes of death in patients with chronic spinal cord injury (SCI). Our previous work showed that pulmonary function can be improved by using our original respiratory training method. However, the effectiveness of this intervention is limited due to the disruption of brain-spinal connections and consequently lowered spinal cord activity below the injury level. Our recent studies showed that electrical stimulation of the spinal cord below the level of injury leads to increased ventilation which indicates activation of the spinal cord structures related to respiration. These findings indicate that spinal cord stimulation can be a promising therapeutic additive to the treatment. The goal of this study is to justify the establishment of a new direction in rehabilitation for patients with SCI by using a non-invasive spinal cord stimulation in combination with respiratory training. Our aims are: 1) to evaluate the effects of such stimulation applied to the injured spinal cord on pulmonary function and respiratory muscle activity, and 2) to evaluate the effectiveness and therapeutic mechanisms of the spinal cord stimulation combined with respiratory training. Thirty-six individuals with chronic SCI will be recruited and assigned to three groups to receive respiratory training or spinal cord stimulation alone or a combination of them. All participants will be tested before and after cycles of experimental procedures with/or without stimulation. Our hypotheses will be confirmed if the respiratory training combined with spinal cord stimulation results in the most enhanced positive effects.

Cingulotomy for Refractory Neuropathic Pain Following Spinal Cord Injury (CRNP-SCI)
Spinal Cord InjuriesNeuropathic PainNeuropathic pain is very common following a spinal cord injury, estimated to affect 43% of patients after 6 months. A proportion of these patients do not respond to treatment and there remains an unmet need to treat people with refractory spinal injury related neuropathic pain. While neuropathic pain medications, baclofen pumps and spinal cord stimulation work for some patients, a significant number are refractory to these therapies. Chronic pain can contribute to loss of functional ability, mental health problems, and a worse quality of life. Studies of functional neuroimaging have shown that the Anterior Cingulate Cortex (ACC) is a key structure in human pain perception, being part of a central pain neuromatrix or medial pain system, which includes thalamic nuclei and periaqueductal grey matter. A similar neuromatrix also including the insula is involved in the regulation of the autonomic nervous system, which explains the well-recognized interactions between pain and autonomic function. Moreover, it has been shown that the ACC is important for the emotional experience and thus the subjective intensity of pain, and it has a role in cognitive control processes for optimizing behaviour in the presence of pain. Bilateral anterior cingulotomy has been demonstrated to be a safe and effective therapeutic option for patients with otherwise intractable pain syndromes of different origins, e.g., refractory pain due to cancer or stroke. Although, cingulotomy has been shown to be a viable option in intractable pain of different origins, there remains a lack of evidence in patients with spinal cord injury and only scanty data are available in literature. Moreover, the effects of cingulotomy on mood, emotion processing, cognition and autonomic reactivity are not clear.

Human-like Robotic Controllers for Enhanced Motor Learning
StrokeSpinal Cord InjuriesThe purpose of this study is to develop a new paradigm to understand how humans physically interact with each other at a single and at multiple joints, with multiple contact points, so as to synthesize robot controllers that can exhibit human-like behavior when interacting with humans (e.g., exoskeleton) or other co-robots. The investigators will develop models for a single joint robot (i.e. at the ankle joint) that can vary its haptic behavioral interactions at variable impedances, and replicate in a multi-joint robot (i.e. at the ankle, knee, and hip joints). The investigators will collect data from healthy participants and clinical populations to create a controller based on our models to implement in the robots. Then, the investigators will test our models via the robots to investigate the mechanisms underlying enhanced motor learning during different human-human haptic interaction behaviors (i.e. collaboration, competition, and cooperation. This study will be carried out in healthy participants, participants post-stroke, and participants with spinal cord injury (SCI).
Chronic Transcutaneous Stimulation to Promote Motor Function and Recovery in Individuals With Paralysis...
Healthy VolunteersSpinal Cord Injury4 moreThis is an early feasibility trial to determine whether transcutaneous neuromuscular electrical stimulation, with or without transcutaneous spinal cord stimulation, using an investigational neurostimulation device improves functional arm/hand movements in individuals with paralysis or paresis due to a spinal cord injury or stroke and improves functional arm/hand or leg/foot movements in individuals with paralysis or paresis due to other brain or nerve injuries. In this study, eligible individuals that agree to participate will be asked to attend up to 5 study sessions a week for 1 year (depending on participant availability), with each session lasting up to 4 hours. At the first study session, participants will have their demographic information collected, vital signs assessed, and have measurements performed of their limbs and torso, as appropriate. They will also undergo clinical evaluations and tests to assess their current functional movement and sensation capabilities. During subsequent study sessions, participants will undergo many tasks designed to improve functional movements in paralyzed limbs. Specifically, participants will receive neuromuscular electrical stimulation to the limb(s) and/or electrical stimulation to the spinal cord to evoke specified movements. The stimulation parameters and locations on the spinal column and/or limb(s) that evoke specific movements will be noted. The movements will be assessed with visual inspection, electromyography, and/or sensors. The clinical evaluations and tests to assess functional movement and sensation capabilities will be repeated throughout the study and at the last study session to assess for functional improvements compared to the first study session. Upon completion of these study sessions, the individual's participation in the study is considered complete.
