Article Synopsis
  • - Individuals with spinal cord injury (SCI) above T6 often experience issues with blood pressure regulation, leading to persistent low blood pressure.
  • - A study tested the effects of daily midodrine (10 mg) versus placebo over 30 days on blood pressure, cerebral blood flow velocity (CBFv), and cognitive performance in hypotensive SCI patients.
  • - Results showed that midodrine significantly increased systolic blood pressure and diastolic CBFv compared to placebo, but did not significantly affect cognitive performance, indicating a need for further research on effective treatments.

Objective: To characterize self-reported health impacts of COVID-19 on people with SCI related to exposure to virus, diagnosis, symptoms, complications of infection, and vaccination.

Methods: The Spinal Cord Injury COVID-19 Pandemic Experience Survey (SCI-CPES) study was administered to ask people with SCI about their health and other experiences during the COVID-19 pandemic.

Context: Early during the COVID-19 pandemic, rehabilitation providers received reports from people with spinal cord injury (SCI) of considerable disruptions in caregiver services, medical and nursing care, and access to equipment and supplies; concomitantly, the medical community raised concerns related to the elevated risk of acquiring the infection due to SCI-specific medical conditions. Due to the novel nature of the pandemic, few tools existed to systematically investigate the outcomes and needs of people with SCI during this emergency.

Objective: To develop a multidimensional assessment tool for surveying the experience of the COVID-19 pandemic on physical and psychological health, employment, caregiving services, medical supplies and equipment, and the delivery of medical care for people with SCI.

Background: Individuals with spinal cord injury (SCI) above thoracic level-6 (T6) experience impaired descending cortical control of the autonomic nervous system which predisposes them to blood pressure (BP) instability, including includes hypotension, orthostatic hypotension (OH), and autonomic dysreflexia (AD). However, many individuals do not report symptoms of these BP disorders, and because there are few treatment options that have been proven safe and effective for use in the SCI population, most individuals remain untreated.

Objective: The primary aim of this investigation was to determine the effects of midodrine (10 mg) prescribed TID or BID in the home environment, compared to placebo, on 30-day BP, study withdrawals, and symptom reporting associated with OH and AD in hypotensive individuals with SCI.

Context/objectives: Wheelchair users with chronic shoulder pain have few options after conservative treatments fail. This pilot study's purpose was to establish safety and treatment effects of micro-fragmented adipose tissue (MFAT) injections under ultrasound guidance for treatment of refractory shoulder pain caused by rotator cuff disease in wheelchair users with spinal cord injury (SCI) to prepare for a larger trial.

Design: Pilot clinical trial.

As the COVID-19 pandemic unfolds, emergency department (ED) personnel will face a higher caseload, including those with special medical needs such as persons living with spinal cord injuries and disorders (SCI/D). Individuals with SCI/D who develop COVID-19 are at higher risk for rapid decompensation and development of acute respiratory failure during respiratory infections due to the combination of chronic respiratory muscle paralysis and autonomic dysregulation causing neurogenic restrictive/obstructive lung disease and chronic immune dysfunction. Often, acute respiratory infections will lead to significant mucus production in individuals with SCI/D, and aggressive secretion management is an important component of successful medical treatment.

Objectives: To develop clinically relevant interpretive standards for the Spinal Cord Injury-Functional Index/Capacity (SCI-FI/C) Basic Mobility and Self-Care item bank scores.

Design: Modified "bookmarking" standard-setting methodology, including 2 stakeholder consensus meetings with individuals with spinal cord injury (SCI) and SCI clinicians, respectively, and a final, combined (consumers and clinicians) "convergence" meeting.

Setting: Two SCI Model System centers in the United States.

Shoulder pain is a common occurrence after spinal cord injury (SCI) and can have significant negative effects on health and function as many individuals with SCI are reliant on their upper extremities for mobility and self-care activities. Shoulder pain after SCI can be caused by acute injury or chronic pathology, but it is most often related to overuse injuries of the rotator cuff. Both acute strain and chronic overuse shoulder injuries in persons with SCI typically result from increased weight bearing on the upper extremities during transfers, weight-relief raises, and wheelchair propulsion, which are often performed in poor postural alignment owing to strength deficits.

Increased pulse wave velocity (PWV), a marker of cardiovascular disease (CVD), has been reported in otherwise healthy individuals with spinal cord injury (SCI) compared with age-matched uninjured controls. Due to decentralized descending sympathetic vascular control, individuals with injuries above T6 are prone to orthostatic hypotension and, as a result, depend on the renin-angiotensin-aldosterone system (RAAS) to maintain orthostatic blood pressure (BP). The purpose of this study was to determine resting PWV, a noninvasive surrogate of central arterial stiffness, in individuals with cervical (C4-T1; = 11) and thoracic (T6-T12; = 11) SCI, compared with age-matched controls (controls; = 11).

Our objective was to determine differences in brain activation during a processing-speed task in individuals with SCI compared to a group of age-matched healthy controls and to a group of older healthy controls. Ten individuals with cervical SCI (C3-C5), 10 age-matched healthy controls and 10 older healthy controls participated in a cross-sectional study in which performance on neuropsychological tests of processing speed and brain activation were the main outcome measures. The brain areas used by the individuals with SCI during the processing-speed task differed significantly from the age-matched healthy controls, but were similar to the older control cohort, and included activation in frontal, parietal and hippocampal areas.

The Americans with Disabilities Act, passed in 1990, represented landmark legislation and led to significant improvements in accessibility, such as prohibiting discrimination based on disability in public life, including employment. Now 30 years later, however, employment rates for persons with disabilities, including spinal cord injury, remain low. This article discusses why employment is so important for persons with spinal cord injury and challenges that remain.

Wheelchair users with spinal cord injury (SCI) have a high risk of developing shoulder pain, caused by rotator cuff disease. Platelet-rich plasma (PRP) is a potential treatment after conservative treatments fail and prior to surgical intervention; however, it has not been tested in wheelchair users who have recalcitrant shoulder pain associated with rotator cuff disease. The objective of this pilot project was to test the safety and potential treatment effect of an ultrasound-guided PRP injection for shoulder pain in the aforementioned population.

Objectives: Individuals with spinal cord injury (SCI) above T6 experience impaired descending cortical control of the autonomic nervous system, which predisposes them to hypotension. However, treatment of hypotension is uncommon in the SCI population because there are few safe and effective pharmacological options available.

The growing field of regenerative rehabilitation has great potential to improve clinical outcomes for individuals with disabilities. However, the science to elucidate the specific biological underpinnings of regenerative rehabilitation-based approaches is still in its infancy and critical questions regarding clinical translation and implementation still exist. In a recent roundtable discussion from International Consortium for Regenerative Rehabilitation stakeholders, key challenges to progress in the field were identified.
