Filter by:The spinal cord is a common site for the development of several neurodegenerative neurological disorders (spinal muscular atrophy or SMA, amyotrophic lateral sclerosis or ALS, X-linked spinal bulbar muscular atrophy or SBMA). In different proportions, these diseases involve axonal loss in large funiculi of the spinal white matter, their demyelination, and loss of ventral horn motor neurons or motoneurones of the spinal gray matter. The lack of specific biomarkers of these macro and microscopic spinal damages, makes it difficult the differential diagnosis and monitoring of these diseases. Techniques to explore non-invasively the human central nervous system, such as magnetic resonance imaging (MRI) and electrophysiology, are potential tools to extract specific biomarkers of spinal damages. However, imaging techniques are still poorly developed at spinal level for technical (specific antennas), anatomical (size of the spinal cord, vertebrae) and physiological reasons (cardio-respiratory movements). However, recent advances in the field of spinal cord imaging allowed to extract quantitative data on neuron loss, axonal degeneration and demyelination in different spinal pathologies whether degenerative (ALS or SMA) or traumatic (SCI). Correlations were found with clinical data, and in ALS patients, the changes in MRI metrics over time paralleled the functional deterioration. The electrophysiological techniques are used since a long time, leading to a good knowledge of the neurophysiology of human spinal cord. In addition, electrophysiology indirectly provides data at a microscopic scale, providing information on the excitability of spinal neural networks and giving an estimate of the amount of functional neurons. By combining these techniques for the investigation of human spinal cord in vivo, the goal is to extract new biomarkers using as study models, diseases of the spinal cord affecting differentially the white and the gray matter (SMA, SBMA and ALS). At first, new methods of diffusion MRI and modelling will be performed in healthy subjects to assess the axonal density and diameter of the fibers in the white matter. The anatomical imaging T2 will measure the geometrical parameters of the spinal cord such as its surface and/or volume at a given vertebral level. Thanks to imaging, we will construct via methods of segmentation and image processing, an atlas of the spinal cord that will allow to locate spatially spinal atrophy in patients. After this phase of validation, A study of patients will be conducted using these new MRI techniques, in addition to those already developed in the laboratory. The contribution of electrophysiology will be to assess more accurately the microscopic damage. Quantitative data from imaging and electrophysiology will be correlated with clinical data in order to extract the most relevant biomarkers. This project has thus a methodological interest by proposing the development of new methods to assess the human spinal cord, at both macro and microscopic levels. These methods are based on the development of the techniques developed at spinal level and which are already applicable to human pathologies. The original combination of imaging and electrophysiology will also enable us to further analyze the human spinal cord, both anatomically and functionally. This project has an important clinical value for the extraction of biomarkers in diseases where there is an unmet need for diagnosis, monitoring, prognosis and evaluation of new therapies.
This study seeks to evaluate the efficacy of nerve transfers in restoring hand function in patients with cervical spinal injuries.
Cervical myelopathy is common among the aging population.One of the complications of cervical myelopathy is balance impairment.In this study, the patients with cervical myelopathy undergo biomechanical, imaging, neurophysiological and functional assessment. Besides, the dynamic balance training is introduced to the patients with cervical decompression surgery.This study is expected to provide important empirical evidence to evaluate the prognosis of the surgery, to further guide the postoperative rehabilitation of myelopathy patients and to improve patients' long-term quality of life.
Sleep-disordered breathing (SDB) remains under-treated in individuals living with spinal cord injuries and disorders (SCI/D). The investigators' aim is to test a program that addresses challenges and barriers to positive airway pressure (PAP) treatment of SDB among patients with SCI/D. The investigators anticipate that patients who receive this program will have higher rates of PAP use and will demonstrate improvements in sleep quality, general functioning, respiratory functioning and quality of life from baseline to 6 months follow up compared to individuals who receive a control program. This work addresses critical healthcare needs for patients with SCI/D and may lead to improved health and quality of life for these patients.
The purpose of this study is to determine the relevant significance of diabetes on cervical disc degeneration, and correlate diabetic control (HgbA1C) with disc glycosylation profile in patients undergoing anterior cervical discectomy and fusion for cervical spondylosis. Additionally, to compare the level of degenerative cervical disc glycosylation in patients with and without diabetes. Hypothesis: Patients with diabetes and degenerative cervical disc disease have higher levels of disc tissue glycosylation, and higher levels of glycosylation are correlated with poor outcomes.
The purpose of this study is to determine what effect intraoperative topical steroids have on reducing swallowing difficulty following Anterior Cervical Discectomy and Fusion surgery.
A Prospective, open label, multi-center observational study of patients requiring surgical treatment at one or two (contiguous) cervical spine levels. The primary objectives of the RHINE Cervical Disc study are to: obtain operative data and feedback on surgical instruments and surgical technique; confirm device performance in terms of clinical and radiographic outcomes; confirm device performance in terms of safety and to collect original data to be compared to published reports of the performance of comparable motion-sparing devices, as well as clinical outcomes of fusion devices.
PANGEA is an international prospective point prevalence study to describe the epidemiology, interventions, and outcomes in children with acute critical brain disease.
Cervical myelopathy is commonly associated with degenerative spinal disease. Dysfunction of the autonomic nervous system is also evident in many cases of cervical myelopathy. Autonomic dysfunction may result in haemodynamic instability and hypotension under anaesthesia. It is important to maintain adequate mean arterial pressure in order to perfuse the spinal cord and prevent cord ischemia. Heart rate variability, the physiological variations of the differences between heart beats, has been used to diagnose autonomic dysfunction. In patients with cervical myelopathy it may enable the anaesthetist to predict hypotension thereby allowing for early treatment and prevention of spinal cord ischemia.
This study will evaluate the efficacy of a newly developed serious game, SCI HARD, to enhance self-management skills, self-reported health behaviors, and quality of life among adolescents and young adults with spinal cord injury and disease (SCI/D). SCI HARD was designed by the project PI, Dr. Meade, in collaboration with the UM3D (University of Michigan three dimensional) Lab between 2010 and 2013 with funding from a NIDRR (National Institute on Disability and Rehabilitation Research) Field Initiated Development Grant to assist persons with SCI develop and apply the necessary skills to keep their bodies healthy while managing the many aspects of SCI care. The study makes a unique contribution to rehabilitation by emphasizing the concepts of personal responsibility and control over one's health and life as a whole. By selecting an innovative approach for program implementation, we also attempt to address the high cost of care delivery and lack of health care access to underserved populations with SCI/D living across the United States (US). H1: SCI Hard participants will show greater improvements in problem solving skills, healthy attitudes about disability, and SCI Self-efficacy than will control group members; these improvements will be sustained over time within and between groups. H2: SCI Hard participants will endorse more positive health behaviors than control group members; these improvements will be sustained over time within and between groups. H3: SCI Hard participants will have higher levels of QOL than control group members; these differences will be sustained over time within and between groups. H4: Among SCI Hard participants, dosage of game play will be related to degree of change in self-management skills, health behaviors and QOL.
