Noninvasive Neuroprosthesis Promotes Cardiovascular Recovery After Spinal Cord Injury.

Neurotherapeutics 2021 Mar 31. Epub 2021 Mar 31.

International Collaboration On Repair Discoveries (ICORD), University of British Columbia, Vancouver, Canada.

Spinal cord injury (SCI) leads to severe impairment in cardiovascular control, commonly manifested as a rapid, uncontrolled rise in blood pressure triggered by peripheral stimuli-a condition called autonomic dysreflexia. The objective was to demonstrate the translational potential of noninvasive transcutaneous stimulation (TCS) in mitigating autonomic dysreflexia following SCI, using pre-clinical evidence and a clinical case report. In rats with SCI, we show that TCS not only prevents the instigation of autonomic dysreflexia, but also mitigates its severity when delivered during an already-triggered episode. Read More

Quantitative analysis of dysautonomia in patients with autonomic dysreflexia.

J Neurol 2021 Feb 25. Epub 2021 Feb 25.

Autonomic Center (NeuroTek), San Juan de Dios Hospital, Santurtzi, Spain.

Autonomic dysreflexia (AD) is a life-threatening condition for individuals with cervical or high-thoracic spinal cord injury (SCI). The profile of autonomic dysfunction in AD using validated clinical autonomic tests has not been described so far, although it could be useful to identify SCI patients at greater risk of developing AD non-invasively. With this objective, 37 SCI patients (27% female) were recruited, and hemodynamic and cardiac parameters were continuously monitored to determine the presence of AD, defined as an increase of systolic blood pressure of 20 mmHg or higher after bladder filling with saline.

Accidental boosting in an individual with tetraplegia - considerations for the interpretation of cardiopulmonary exercise testing.

J Spinal Cord Med 2021 Jan 29:1-6. Epub 2021 Jan 29.

International Collaboration on Repair Discoveries (ICORD), Faculty of Medicine, University of British Columbia (UBC), Vancouver, Canada.

Context: Autonomic dysreflexia (AD), characterized by a transient increase in systolic blood pressure (BP), is experienced by individuals with spinal cord injury (SCI) and can be purposefully induced ('boosting') to counteract autonomic dysfunction that impairs cardiovascular responses to exercise. Herein, we demonstrate the impact of unintentional boosting observed during cardiopulmonary exercise testing (CPET) in an inactive male with SCI (C5, motor-complete).

Findings: On two separate occasions the individual performed a standard arm-crank CPET (1-min stages, 7W increase in resistance) following by a longer CPET (4-min stages, 12W increase in resistance), both to volitional exhaustion. Read More

Acute post-injury blockade of α2δ-1 calcium channel subunits prevents pathological autonomic plasticity after spinal cord injury.

Cell Rep 2021 Jan;34(4):108667

Department of Neuroscience, Belford Center for Spinal Cord Injury, The Ohio State University, Columbus, OH 43210, USA. Electronic address:

After spinal cord injury (SCI), normally innocuous visceral or somatic stimuli can trigger uncontrolled reflex activation of sympathetic circuitry, causing pathological dysautonomia. We show that remarkable structural remodeling and plasticity occur within spinal autonomic circuitry, creating abnormal sympathetic reflexes that promote dysautonomia. However, when mice are treated early after SCI with human-equivalent doses of the US Food and Drug Administration (FDA)-approved drug gabapentin (GBP), it is possible to block multi-segmental excitatory synaptogenesis and abolish sprouting of autonomic neurons that innervate immune organs and sensory afferents that trigger pain and autonomic dysreflexia (AD).

Improvements in Bladder Function Following Activity-Based Recovery Training With Epidural Stimulation After Chronic Spinal Cord Injury.

Front Syst Neurosci 2020 5;14:614691. Epub 2021 Jan 5.

Kentucky Spinal Cord Injury Research Center, University of Louisville, Louisville, KY, United States.

Spinal cord injury (SCI) results in profound neurologic impairment with widespread deficits in sensorimotor and autonomic systems. Voluntary and autonomic control of bladder function is disrupted resulting in possible detrusor overactivity, low compliance, and uncoordinated bladder and external urethral sphincter contractions impairing storage and/or voiding. Conservative treatments managing neurogenic bladder post-injury, such as oral pharmacotherapy and catheterization, are important components of urological surveillance and clinical care. Read More

Is autonomic dysreflexia a cause of respiratory dysfunction after spinal cord injury?

Spinal Cord Ser Cases 2021 Jan 19;7(1). Epub 2021 Jan 19.

Spinal Cord Injury Unit, Department of Physical Medicine and Rehabilitation, Hospital Santo António, Medical School, Instituto de Ciências Biomédicas Abel Salazar, Porto University, Porto, Portugal.

Introduction: Spinal cord injury (SCI) often leads to impairment of the respiratory system. In fact, respiratory insufficiency is a significant cause of mortality and morbidity following SCI, related to the extent and level of the neurologic injury and its effects on the respiratory muscles (reduction in respiratory muscle strength and fatigue due to a reduction in inspiratory capacity, atelectasis and ineffective coughing). Less commonly recalled is the fact that autonomic dysreflexia (AD) is the result of parasympathetic imbalance. Read More

Pharmacological Inhibition of Soluble Tumor Necrosis Factor-Alpha Two Weeks after High Thoracic Spinal Cord Injury Does Not Affect Sympathetic Hyperreflexia.

J Neurotrauma 2021 Feb 1. Epub 2021 Feb 1.

Department of Neurobiology and Anatomy, Marion Murray Spinal Cord Research Center, Drexel University College of Medicine, Philadelphia, Pennsylvania, USA.

After a severe, high-level spinal cord injury (SCI), plasticity to intraspinal circuits below injury results in heightened spinal sympathetic reflex activity and detrimentally impacts peripheral organ systems. Such sympathetic hyperreflexia is immediately apparent as an episode of autonomic dysreflexia (AD), a life-threatening condition characterized by sudden hypertension and reflexive bradycardia following below-level sensory inputs; for example, pressure sores or impacted fecal matter. Over time, plasticity within the spinal sympathetic reflex (SSR) circuit contributes to the progressive intensification of AD events, as the frequency and severity of AD events increase greatly beginning ∼2 weeks post-injury (wpi).

[Autonomic hyperreflexia after spinal cord injury : perioperative management].

Rev Med Liege 2020 Oct;75(10):660-664

Département d'Anesthésie-Réanimation, CHU Liège, Belgique.

Spinal cord injury can have widespread consequences beyond the disruption of sensory and motor functions. Injury at or above the sixth thoracic spinal cord segment frequently leads to dysregulation of the autonomic nervous system, which results in a syndrome called autonomic hyperreflexia or dysreflexia. It is a hypertensive crisis triggered by visceral or somatic stimuli below the level of the injury and caused by sympathetic spinal reflexes not modulated by regulatory centers in the brain.

Senior Lecturer Advanced Practice, University of South Wales, Pontypridd.

Autonomic dysreflexia (AD) is an uncontrolled increase in systolic blood pressure (by 20 mmHg or more) that occurs in those with spinal cord injuries at or above the 6th thoracic vertebrae. It usually occurs in the chronic phase of injury, at between 3 and 6 months after the injury is sustained. Most affected patients live in the community with varying levels of independence and will have contact with community nurses due to potential issues with bladder and bowel management. Read More
