ReviewModels of Care Delivery From Rehabilitation to Community for Spinal Cord Injury: A Scoping Review.
Spinal cord injury (SCI) is a chronic condition that results in high healthcare utilization and lifetime cost across the care continuum. In the absence of a standardized model of care delivery for SCI in western countries such as Canada, a scoping review of the literature was performed to identify and summarize existing international SCI models of care delivery. Four databases were searched using key words and subject headings for concepts such as: "spinal cord injury," "delivery of healthcare," "model of care," "patient care planning," and "care pathway." Title, abstract, and full text review were competed by two independent reviewers. ⋯ No single SCI model of care has been adopted across different countries internationally. However, optimal attributes of models of care were identified, including the importance of having multidisciplinary SCI specialty care providers along the continuum, provision of rural SCI services and outreach, integration of primary care, peer mentoring, and using a hub and spokes model of care. These findings inform the future development of an SCI model of care, which ideally would serve all geographical locations and span the continuum of care, improving the health status and quality of life of persons with SCI.

Clinical Protocol for Identifying and Managing Bladder Dysfunction during Acute Care after Traumatic Spinal Cord Injury.
Bladder dysfunction is widespread following traumatic spinal cord injury (TSCI). Early diagnosis of bladder dysfunction is crucial in preventing complications, determining prognosis, and planning rehabilitation. We aim to suggest the first clinical protocol specifically designed to evaluate and manage bladder dysfunction in TSCI patients during acute care. ⋯ The proposed protocol is specifically adapted to the dynamic nature of neurogenic bladder function following TSCI. The assessment of VAC into the protocol provides major insight on the potential for reaching adequate bladder function during the subacute phase. Conducting TOV using bladder scan residuals in patients with VAC is a non-invasive and easy method to discriminate between a functional and an impaired bladder following acute TSCI.

Trends in Demographics and Markers of Injury Severity in Traumatic Cervical Spinal Cord Injury.
Over the past four decades, there have been progressive changes in the epidemiology of traumatic spinal cord injury (tSCI). We assessed trends in demographic and injury-related variables in traumatic cervical spinal cord injury (tCSCI) patients over an 18-year period at a single Level I trauma center. We included all magnetic resonance imaging-confirmed tCSCI patients ≥15 years of age for years 2001-2018. ⋯ In adjusted regression models, increase in age and decreases in prevalence of MVC mechanism and complete injuries over time remained statistically significant. Changes in demographic and injury-related characteristics of tCSCI patients over time may help explain the observed improvement in outcomes. Further, improved clinical outcomes and drop in IMLL may reflect improvements in initial risk assessment and pre-hospital management, advances in healthcare delivery, and preventive measures including public education.

Spinal dopaminergic mechanisms regulating the micturition reflex in male rats with complete spinal cord injury.
Traumatic spinal cord injury (SCI) often causes micturition dysfunction. We recently discovered a low level of spinally-derived dopamine (DA) that regulates recovered bladder and sphincter reflexes in SCI female rats. Considering substantial sexual dimorphic features in the lower urinary tract, it is unknown if the DA-ergic mechanisms act in the male. ⋯ Further, intrathecal delivery of SCH 23390 and quinpirole resulted in similar responses to those with i.v. delivery, respectively, which indicates the central action regardless of delivery route. In addition, metabolic cage assays showed that quinpirole increased the voiding frequency and total voiding volume in spontaneous micturition. Collectively, spinal DA-ergic machinery regulates recovered micturition reflex following SCI in male rats; spinal DR1 tonically suppress tonic EUS activity to enable voiding and activation of DR2 facilitates voiding.

Intensive locomotor training provides sustained alleviation of chronic spinal cord injury associated neuropathic pain: A 2-year preclinical study.
Neuropathic pain often accompanies the functional deficits associated with spinal cord injury (SCI) and further reduces a patient's quality of life. Clinical and pre-clinical research is beginning to highlight the beneficial role that rehabilitative therapies such as locomotor training can have not only on functional recovery but also on chronic pain management. Our group has previously developed an intensive locomotor training (ILT) treadmill protocol on rats that reduced SCI neuropathic pain symptoms for at least 3 months. ⋯ In addition, prolonged survival and improved locomotor outcomes were observed in rats undergoing ILT as the study longevity progressed. Potential contributory mechanisms underlying beneficial effects of ILT include reduced inflammation and restoration of anti-nociceptive inhibitory processes as indicated by neurochemical assays in spinal tissue of remaining rats at 2 years post-SCI. The benefits of chronic ILT suggest that long-term physical exercise therapy can produce powerful and prolonged management of neuropathic pain, partly through sustained reduction of spinal pathological processes.
