Biomarkers of Spontaneous Recovery From Traumatic Spinal Cord Injury
Spinal Cord InjuryThe purpose of the study is to profile biochemical responses and measure functional recovery in parallel, throughout the 1st year after spinal cord injury (SCI), within the same participants. These responses and recovery will be evaluated in samples from people who have had a spinal cord injury due to trauma (e.g. car accident or a fall) within the first year after SCI. Specifically, the investigators will test the hypothesis that a subset of inflammatory biomarkers correlate inversely with functional recovery. The investigators will use these data to build a predictive model of functional recovery after SCI that incorporates biomarkers that can be easily quantified in the clinic. Total anticipated enrollment will be 100 participants with SCI across three different sites (Northwell Health System (NY), The Kessler Institute for Rehabilitation (NJ), University of Louisville (KY) and may enroll up to 30 participants without SCI.
Magnetic Resonance Imaging Studies of Motor and Thought Processes
Cerebrovascular DisorderHealthy3 moreMagnetic resonance imaging (MRI) is a diagnostic tool that creates high quality images of the human body without the use of X-ray (radiation). MRI is especially useful when studying the brain, because it can provide information about certain brain functions. In addition, MRI is much better than standard X-rays at showing areas of the brain close to the skull and detecting changes in the brain associated with neurological diseases. In this study researchers will use MRI to gather information about the processes that control human movement and sensory processing. The purpose of the study is to investigate how the brain is activated when remembering, thinking, or recognizing objects. Researchers would like to determine what happens to brain functions when patients have trouble remembering, thinking, or recognizing objects following the start of disorders in the brain and nervous system. In addition, this study will investigate the processes of motor control in healthy volunteers and patients with disease.

Brain/Neural Hand Exoskeleton Control for Restoration of Bimanual Tasks
Spinal Cord InjuryStrokeThis study investigates whether spinal cord injury and stroke survivors (n=10) are able to operate a brain/neural hand exoskeleton (B/NHE) based on electroencephalography (EEG) and electrooculography (EOG) for restoration of bimanual activities of daily living (ADLs). To assess bimanual ADLs, the Berlin Bimanual Task Assessment (BEBITA) will be applied. Improvements in BEBITA will be evaluated with and without B/NHE use.

Characterization of the Changes in the Signalling Pathways During Spinal Cord Injury-induced Skeletal...
Spinal Cord InjuriesMuscle AtrophyAtrogin-1 and muscle RING finger-1 are skeletal muscle specific genes, with ubiquitin ligase activities, that are upregulated during muscle atrophy in mice. The Akt/GSK3 and Akt/mTOR pathways are involved in muscle hypertrophy in mice. Recent studies by the investigators team and others have demonstrated the implication of these signalling pathways in the control of muscle mass in humans. However no study has yet investigated the involvement of these systems in the early stages of spinal cord injury induced human skeletal muscle atrophy. The investigators propose to investigate the level of expression of the different components of the ubiquitin-proteasome system together with the level of expression and activity of the Akt/mTOR and Akt/GSK3 signalling pathways after SCI in humans during the first months following the injury. A second aim of this project is to assess if a novel apparatus of electrical stimulation which generate movements by closed-loop electrical muscle stimulation may improve strength and muscle mass in these patients. The patients will be recruited jointly at the Clinique Romande de Réadaptation (CRR) in Sion and the Swiss paraplegic centre in Nottwil. They will be randomly divided into two groups, a first group of patients will undergo a conventional treatment of rehabilitation while a second set of patients will be treated using a brand new system of electro-stimulation called MotionMaker TM. Biopsies will be obtained in the first weeks after admission; two other biopsies will be taken respectively 3 and 6 months post-lesion. Our results will provide an increased understanding of the molecular mechanisms contributing to skeletal muscle atrophy during the early stages following SCI and a characterization of the impact of endurance training in the no more voluntary innervated muscle. Moreover this study will also investigate the potential improvement in the rehabilitation process by using a new system of electro-stimulation.

Freehand Ultrasound to Evaluate Scapular Kinematics in People With Paraplegia
Spinal Cord InjuriesShoulder Impingement SyndromeShoulder pain is very common in people with spinal cord injury (SCI). Persons with high-level paraplegia have higher chances to suffer shoulder pain and injury than those with lower-level paraplegia due to the shoulder muscle imbalance. As people with SCI overuse the shoulder during routine daily activities, the onset of pain or injury lead to increased healthcare expenses, limitation in activity, depression, decreased participation, and reduced quality of life. One of the main reasons of shoulder pain is believed to have a altered scapular movement. To clarify the mechanism of the shoulder pain and injury, comprehensive understanding of three-dimensional scapular kinematics is required. Ultrasound is a low-cost and non-invasive imaging system and has been used to diagnose the shoulder pain and injury in individuals with SCI. A freehand ultrasound (FUS) combining ultrasound with motion capture system to evaluate scapular movement was developed and presented favorable results in able-bodied population. The purpose of this study is to compare the FUS and widely used skin-based method against a radiographic based gold standard in people with paraplegia, and to elucidate the relationship among scapular movement and shoulder pain, pathology. This study will also allow us to gain more understanding of how level of injury influences the scapular behavior during functional activities. The investigators believe more severe shoulder pain and pathology will be associated with greater abnormal scapular movement. The investigators also believe that people with high-level paraplegia will have greater scapular abnormality than people with low-level paraplegia during arm elevation and weight relief raise tasks. By completing this study, the investigators will expect to deliver a reliable and valid tool to evaluate scapular movement and gain a better understanding how the altered scapular movement is related to shoulder pain and pathology. The investigators will also learn how the level of injury affects the scapular behavior during functional activities. The results of this study may help the shoulder pain management leading to the improvement in the quality of life of individuals with SCI.
CLINICAL EFFECT OF BOTULINUM TOXIN TYPE A IN TREATMENT OF SPASTICITY
SpasticityBrain Injuries2 moreSpasticity has been defined as a disorder of the sensorimotor system characterized by a velocity-dependent increase in tonic stretch reflexes (muscle tone) with exaggerated tendon jerks, resulting from hyperexcitability of the stretch reflex. The treatment goal of spasticity is Medical treatment generally combines physiotherapy with medications, depending on spasticity distribution. Systemic treatments such as oral or intrathecal baclofen are generally considered in case of generalized spasticity, whereas local treatments are considered in case of focal spasticity. Local treatments such as Botulinum Toxin type A, phenol, and alcohol present several advantages, allowing to treat of selected muscles without the risk of sedation. As stated above, they are indicated for focal spasticity but might be helpful even in the presence of generalized spasticity with identified focal goals (Bethoux et al., 2015). In particular, Botulinum Toxin type A (BoNT-A) is considered the gold standard treatment for focal spasticity, showing a level A evidence for spasticity reduction in upper- and lower-limb spasticity (Simpson et al., 2016). However, current evidence is mainly focused on post-stroke spasticity (Franceschini et al., 2014), whereas it is still limited in spasticity as a consequence of other aetiologies, such as spinal cord injury (SCI), traumatic brain injury (TBI), or multiple sclerosis (MS). Interestingly, spasticity is a major concern for the rehabilitation of these patients. The aim of this observational study is the evaluation of the clinical efficacy of BoNT-A in spasticity reduction in patients affected by neurological conditions different from post-stroke spasticity, such as SCI, TBI, and MS.
