Subtle and profound changes in autonomic nervous system (ANS) function affecting
sympathetic and parasympathetic homeostasis occur as a result of critical illness. Changes …

Unstable blood pressure after spinal cord injury (SCI) is not routinely examined but rather
predicted by level and completeness of injury (ie, American Spinal Injury Association …

Autonomic dysfunction after spinal cord injury (SCI) is profound and ranges greatly based on
spinal level of injury and the extent to which autonomic pathways are disrupted. In high-level …

Background Early screening is important in individuals with spinal cord injury (SCI) as they
are deemed high risk for cardiometabolic diseases. Few studies explored changes in …

Purpose Bolus water drinking, at room temperature, has been shown to improve orthostatic
tolerance (OT), probably via sympathetic activation; however, it is not clear whether the …

Pulse rate variability (PRV) is often used as an alternative to heart rate variability (HRV) to
measure psychophysiological function. However, its validity to do so is unclear, especially in …

Background Heart rate variability is a measure of autonomic activity that is growing in
popularity as a research outcome. However, despite its increased use, the known effects of …

Autonomic dysfunction is a prominent concern following spinal cord injury (SCI). In
particular, autonomic dysreflexia (AD; paroxysmal hypertension and concurrent bradycardia …

Injury to descending autonomic (sympathetic) pathways is common after high-level spinal
cord injury (SCI) and associated with abnormal blood pressure and heart rate regulation. In …

Heart rate variability biofeedback (HRV-F) is a neurocardiac self-regulation therapy that
aims to regulate cardiac autonomic nervous system activity and improve cardiac balance …
