The Valsalva maneuver (VM) is a diagnostic protocol examining sympathetic and
parasympathetic activity in patients with autonomic dysfunction (AD) impacting …

Purpose Early postoperative mobilization can be hindered by orthostatic intolerance (OI).
Postoperative OI has multifactorial pathogenesis, possibly involving both postoperative …

The aim of this study was to characterize autonomic lesions in participants with spinal cord
injury (SCI; n= 10) using an autonomic reflex screen, incorporating sudomotor, cardiovagal …

Background and Purpose Many elderly patients are unable to actively stand up by
themselves and have contraindications to performing the head-up tilt test (HUTT). We aimed …

Background: Standard autonomic testing includes a 10-minute head-up tilt table test to
detect orthostatic hypotension. Although this test can detect delayed orthostatic hypotension …

Objective To investigate the inflammatory biomarker signature associated with classical
orthostatic hypotension (OH). Methods A cross-sectional study including 778 patients with …

Orthostatic hypotension (OH) is a form of orthostatic intolerance (OI) and a key physiological
indicator of autonomic dysfunction that is associated with an increased risk of major …

Purpose Hippocampal dysfunction plays a key role in the pathology of psychosis. Given
hippocampal sensitivity to changes in cerebral perfusion, decreased baroreflex function …

Spinal cord injury (SCI) often results in the devastating loss of motor, sensory, and
autonomic function. After SCI, the interruption of descending sympathoexcitatory pathways …

Objective: To determine the test-retest reliability of quantitative and qualitative baroreflex
sensitivity (BRS) parameters derived from the Valsalva maneuver (VM) in individuals with …
