Filter by:This study looks to characterize gradients of dysfunction in the autonomic nervous system after spinal cord injury. The autonomic nervous system plays key roles in regulation of blood pressure, skin blood flow, and bladder health- all issues that individuals with spinal cord injury typically suffer. Focusing on blood pressure regulation, the most precise metric with broad clinical applicability, the investigators will perform laboratory-based tests to probe the body's ability to generate autonomic responses. For both individuals with spinal cord injury and uninjured controls, laboratory-based experiments will utilize multiple parallel recordings to identify how the autonomic nervous system is able to inhibit and activate signals. The investigators anticipate that those with autonomic dysfunction after spinal cord injury will exhibit abnormalities in these precise metrics. The investigators will further have research participants wear a smart watch that tracks skin electrical conductance, heart rate, and skin temperature, which can all provide clues as to the degree of autonomic dysfunction someone may suffer at home. The investigators will look to see if any substantial connections exist between different degrees of preserved autonomic function and secondary autonomic complications from spinal cord injury. In accomplishing this, the investigators hope to give scientists important insights to how the autonomic nervous system works after spinal cord injury and give physicians better tools to manage these secondary autonomic complications.
Secondary tethered cord syndrome (STCS) has been diagnosed with signs of progressive deterioration in urological or neuroorthopedic systems following primary tethering surgery. However, there is no convincing urological diagnostic clue for STCS.
This study is non-randomized, multicenter, confirmatory study by intrathecal administration of KP-100IT, code of HGF (Hepatocyte Growth Factor ) formulation for intrathecal injection, in subjects with acute spinal cord injury.
Managing a spinal cord injury (SCI) is a life-long process. Within the first year of injury, more than 50% of people discharged with a SCI may require re-hospitalization due to a secondary complication, such as a urinary tract infection, pressure ulcer or pneumonia. Even 20 years post-injury, re-hospitalization rates remain over 30%. While re-hospitalization rates in Canada have remained high for more than 10 years, the length of stay in inpatient rehabilitation has decreased dramatically, thereby limiting the time for provision of health information and skill acquisition in the inpatient rehabilitation setting. There is growing evidence from two recent pilot trials to suggest that self-management programs that provide appropriate health information, skills and telephone-based support for community-dwelling patients with SCI improves health behaviors and leads to reductions in re-hospitalization. Goals/Research Aim: To conduct a pilot RCT (feasibility study) that will inform the design of a definitive RCT to determine whether an online self-management program incorporating trained peer health coaches (called "SCI&U") compared to usual care will result in improved self-management skills (short-term outcome) and lead to reduced days of hospitalization (long-term outcome) due to secondary complications.This pilot study is a two-group RCT with an embedded qualitative component. The target population is adults with SCI who have been discharged from inpatient rehabilitation and living in the community. Sixty subjects will be recruited from across Canada with a focus on British Columbia and Ontario and randomly assigned to the SCI&U intervention or usual care. Evaluations will occur at baseline, 2, 6, and 12 months.
It has been hypothesized that there are two mechanisms of acute traumatic spinal cord injury (SCI): the primary mechanical damage and the secondary injury due to additional pathological processes initiated by the primary injury. Neurological damage due to laceration, contusion, distraction or compression of the spinal cord is called ''primary injury''. This mechanical injury leads to a cascade of biochemical and pathological changes, described as ''secondary injury'', which occurs minutes to weeks after the initial trauma and causes further neurological deterioration. This secondary cascade involves vascular changes, an inflammatory response, neurotoxicity, apoptosis and glial scarring, and further compromises neurological impairment after traumatic spinal cord injury. Edema, ischemia and loss of autoregulation continue to spread bi-directionally from the initial lesion along the spinal cord for up to 72 hours after the trauma. It has been postulated that the damage caused by the primary injury mechanism is irreversible and therapeutic approaches in recent years have focused on modulating the secondary injury cascade. Researchers found significantly greater numbers of myelinated fibers in peripheral nerves after a single ESWT application in an experimental model on rats after a homotopic nerve autograft into the sciatic nerve. In another study a spinal cord ischemia model in mice was performed. ESWT was applied immediately after surgery and the treated animals showed a significantly better motor function and decreased neuronal degeneration compared to the control group within the first 7 days after surgery. Researchers investigated the effect of low-energy ESWT for the duration of three weeks on a thoracic spinal cord contusion injury model in rats. Animals in the ESWT group demonstrated significantly better locomotor improvement and reduced neuronal loss compared to the control animals at 7, 35, and 42 days after contusion. It has been postulated previously, that ESWT improves the metabolic activity of various cell types and induces an improved rate of axonal regeneration. ESWT might be a promising therapeutic strategy in the treatment of traumatic SCI. The underlying study aims to investigate the effect of ESWT after acute traumatic spinal cord injury in humans within 48 hours of trauma in order to intervene in the secondary injury phase with the objective to reduce the extent of neuronal damage.
This study examines the role of the GABA-B receptor in long-lasting presynaptic inhibition of primary afferents in human participants. Participants will come in for two visits, receiving baclofen (a GABA-B receptor agonist) on one visit and a placebo during the other. Electro-physiological measures will be use during both visit to asses presynaptic inhibition.
This project adds to non-invasive BCIs for communication for adults with severe speech and physical impairments due to neurodegenerative diseases. Researchers will optimize & adapt BCI signal acquisition, signal processing, natural language processing, & clinical implementation. BCI-FIT relies on active inference and transfer learning to customize a completely adaptive intent estimation classifier to each user's multi-modality signals simultaneously. 3 specific aims are: 1. develop & evaluate methods for on-line & robust adaptation of multi-modal signal models to infer user intent; 2. develop & evaluate methods for efficient user intent inference through active querying, and 3. integrate partner & environment-supported language interaction & letter/word supplementation as input modality. The same 4 dependent variables are measured in each SA: typing speed, typing accuracy, information transfer rate (ITR), & user experience (UX) feedback. Four alternating-treatments single case experimental research designs will test hypotheses about optimizing user performance and technology performance for each aim.Tasks include copy-spelling with BCI-FIT to explore the effects of multi-modal access method configurations (SA1.3a), adaptive signal modeling (SA1.3b), & active querying (SA2.2), and story retell to examine the effects of language model enhancements. Five people with SSPI will be recruited for each study. Control participants will be recruited for experiments in SA2.2 and SA3.4. Study hypotheses are: (SA1.3a) A customized BCI-FIT configuration based on multi-modal input will improve typing accuracy on a copy-spelling task compared to the standard P300 matrix speller. (SA1.3b) Adaptive signal modeling will allow people with SSPI to typing accurately during a copy-spelling task with BCI-FIT without training a new model before each use. (SA2.2) Either of two methods of adaptive querying will improve BCI-FIT typing accuracy for users with mediocre AUC scores. (SA3.4) Language model enhancements, including a combination of partner and environmental input and word completion during typing, will improve typing performance with BCI-FIT, as measured by ITR during a story-retell task. Optimized recommendations for a multi-modal BCI for each end user will be established, based on an innovative combination of clinical expertise, user feedback, customized multi-modal sensor fusion, and reinforcement learning.
Manual wheelchairs allow individuals with spinal cord injuries (SCI) to safely and effectively access their environment. However, continual exposure to whole body vibration (WBV) is one of many contributing factors to neck pain, back pain, and fatigue in wheelchair users with SCI. Vibration-reducing in-wheel suspension has the potential to mitigate issues associated with long-term manual wheelchair propulsion. Evidence is lacking on how well these systems work for reducing harmful shock and vibration, pain and fatigue. The purpose of this study is to examine how these wheels change the vibration levels manual wheelchair users are exposed to and how they impact pain and fatigue.
To identify means to improve exercise performance in participants with tetraplegia.
This pilot study will determine the feasibility of implementing a combinatory rehabilitation strategy involving testosterone replacement therapy (TRT) with locomotor training (LT; walking on a treadmill with assistance and overground walking) in men with testosterone deficiency and walking dysfunction after incomplete or complete spinal cord injury. The investigators hypothesize that LT+TRT treatment will improve muscle size and bone mineral density in men with low T and ambulatory dysfunction after incomplete or complete SCI, along with muscle fundtion and walking recovery in men with T low and ambulatory dysfunction ater incomplete SCI.
