Long COVID (LC) affects physical health and cognition, limiting participation in social and leisure activities. As a novel disabling condition following a COVID-19 infection, informal caregivers of those with LC have taken on expanded roles, including educating themselves on this diagnosis. Gathering insights from people living with LC (PWLC) and their caregivers is crucial for understanding its impact on well-being and identifying targeted rehabilitation practices across the LC care pathway.

Objectives: To describe the performance of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) examination in individuals with traumatic spinal cord injury (TSCI) and nontraumatic spinal cord injury (NTSCI) across Canadian acute and rehabilitation facilities, evaluating timing, completeness, and classification accuracy.

Methods: Using the Rick Hansen Spinal Cord Injury Registry (2015-2022), participants were analyzed across 6 cohorts: (A) TSCI-acute-admission ( = 4461), (B) TSCI-acute-discharge ( = 972), (C) TSCI-rehabilitation-admission ( = 2673), (D) TSCI-rehabilitation-discharge = 2316), (E) NTSCI-rehabilitation-admission ( = 728), and (F) NTSCI-rehabilitation-discharge = 619). ISNCSCI data included performed (yes/no), timing (≤72 hours, ≤7 days, and >7 days of admission/discharge), completeness, missing items, and worksheet used (yes/no).

Background: Medications are among the most common health interventions, with certain populations, such as individuals with spinal cord injury/dysfunction (SCI/D), commonly prescribed multiple medications. Consequently, adults with SCI/D often engage in activities related to medication self-management, but there are few comprehensive resources for this population. The objective of this study was to co-design the prototype of a toolkit to support medication self-management among adults with SCI/D.

The purpose of our study was to develop a toolkit to facilitate the implementation of functional electrical stimulation (FES) cycling for persons with a newly acquired spinal cord injury (SCI) in the acute care inpatient hospital setting. The researchers and community members used participatory action as a research approach to co-create the toolkit. We held two focus groups to develop drafts, with a third meeting to provide feedback, and a fourth meeting to evaluate the toolkit and determine dissemination strategies.

Introduction: Common, consumer-grade biosensors mounted on fitness trackers and smartwatches can measure an array of biometrics that have potential utility in post-discharge medical monitoring, especially in remote/rural communities. The feasibility characteristics for wrist-worn biosensors are poorly described for post-COVID conditions and rural populations.

Methods: We prospectively recruited patients in rural communities who were enrolled in an at-home rehabilitation program for post-COVID conditions.

Upper extremity pain and injury are among the most common musculoskeletal complications manual wheelchair users face. Assessing the temporal parameters of manual wheelchair propulsion, such as propulsion duration, cadence, push duration, and recovery duration, is essential for providing a deep insight into the mobility, level of activity, energy expenditure, and cumulative exposure to repetitive tasks and thus providing personalized feedback. The purpose of this paper is to investigate the use of inertial measurement units (IMUs) to estimate these temporal parameters by identifying the start and end time of hand contact with the push-rim during each propulsion cycle.

The neuropathological sequelae of stroke and subsequent recovery are incompletely understood. Here, we investigated the metabolic dynamics following stroke to advance the understanding of the pathophysiological mechanisms orchestrating stroke recovery. Using a nuclear magnetic resonance (NMR)-driven metabolomic profiling approach for urine samples obtained from a clinical group, the objective of this research was to (1) identify novel biomarkers indicative of severity and recovery following stroke, and (2) uncover the biochemical pathways underlying repair and functional recovery after stroke.

On demand and localized treatment for excessive muscle tone after spinal cord injury (SCI) is currently not available. Here, we examine the reduction in leg hypertonus in a person with mid-thoracic, motor complete SCI using a commercial transcutaneous electrical stimulator (TES) applied at 50 or 150 Hz to the lower back and the possible mechanisms producing this bilateral reduction in leg tone. Hypertonus of knee extensors without and during TES, with both cathode (T11-L2) and anode (L3-L5) placed over the spinal column (midline, MID) or 10 cm to the left of midline (lateral, LAT) to only active underlying skin and muscle afferents, was simultaneously measured in both legs with the pendulum test.

Evaluating the experiences of persons with spinal cord injury (PwSCI) regarding their transitions in care and changes in health, function, and quality of life is complex, fragmented, and involves multiple tools and measures. A staged protocol was implemented with PwSCI and relevant expert stakeholders initially exploring and selecting existing measures or tools through a modified Delphi process, followed by choosing one of two options. The options were to either support the use of the 10 selected tools from the Delphi method or to co-develop one unique condensed tool with relevant measures to evaluate all four domains.

Objective: Fatigue, headache, problems sleeping and numerous other symptoms have been reported to be associated with long COVID. However, many of these symptoms coincide with symptoms reported by the general population, possibly exacerbated by restrictions/precautions experienced during the COVID-19 pandemic. This study examines the symptoms reported by individuals who tested positive for COVID-19 compared with those who tested negative.

Metabolomic biomarkers hold promise in aiding the diagnosis and prognostication of traumatic brain injury. In Canada, over 165,000 individuals annually suffer from a traumatic brain injury (TBI), making it one of the most prevalent neurological conditions. In this pilot investigation, we examined blood-derived biomarkers as proxy measures that can provide an objective approach to TBI diagnosis and monitoring.

Background: Balance parameters derived from wearable sensor measurements during postural sway have been shown to be sensitive to experimental variables such as test duration, sensor number, and sensor location that influence the magnitude and frequency-related properties of measured center-of-mass (COM) and center-of-pressure (COP) excursions. In this study, we investigated the effects of test duration, the number of sensors, and sensor location on the reliability of standing balance parameters derived using body-mounted accelerometers.

Methods: Twelve volunteers without any prior history of balance disorders were enrolled in the study.

Background: COVID-19 disrupted services received by persons with spinal cord injury (SCI) worldwide. The International Disability Alliance declared the need for a disability-inclusive response to the COVID-19 crisis, as decreased access to health care services for individuals living with varying levels of function was unacceptable. As a result, an SCI community in Canada created a novel webinar-based strategy aimed at improving access to self-management information for people living with SCI and other stakeholders.
