Functional Disability in Adolescents With Orthostatic Intolerance and Chronic Pain

, 2011
A retrospective review identified 99 adolescents (79% female) referred to a tertiary care center to evaluate the relationship between symptoms of orthostatic intolerance and chronic pain.

The Benefits of Oral Rehydration on Orthostatic Intolerance in Children with Postural Tachycardia Syndrome

, 2019
OBJECTIVE: To evaluate whether equal volumes of oral rehydration solution (ORS) or intravenous (IV) saline provide similar improvements in cardiovascular status during controlled orthostatic challenge when administered to subjects with postural ...

Demographic and clinical features of pediatric patients with orthostatic intolerance and an abnormal head-up tilt table test; A retrospective descriptive study

Pediatrics and Neonatology, 2020
Background: Clinical presentation varies in children with Orthostatic Intolerance. This study aimed to evaluate the epidemiological and clinical characteristics of pediatric patients with orthostatic intolerance (OI) and positive head-up tilt test (HUTT).

Sex differences in dynamic cerebral autoregulation responses to resistance and endurance training in humans

Experimental Physiology, EarlyView.
Abstract Exercise maintains brain health and reduces the risk of cerebrovascular diseases, such as stroke and dementia. The benefits of different ‘modalities’ of exercise on male and female cerebral autoregulation are unclear. In this study, we compared adaptations in dynamic cerebral autoregulation (dCA) during spontaneous and forced oscillations in ...

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Neural autonomic control in orthostatic intolerance

, 2009
Inability to maintain the upright position is manifested by a number of symptoms shared by either human pathophysiology and conditions following weightlessness or bed rest.

Neurohumoral mechanisms associated with orthostasis: Reaffirmation of the significant contribution of the heart rate response

Frontiers in Physiology, 2014
The inability to compensate for acute central hypovolemia underlies the clinical development of orthostatic hypotension and instability (e.g., syncope). Although neuro-humoral control of both cardiac output and peripheral vascular resistance contributes ...

Thermal and cardiovascular responses to sauna are attenuated by adding cold water immersion to cooling breaks

Experimental Physiology, EarlyView.
Abstract The independent effects of different cooling practices, such as cold‐water immersion (CWI), on thermal and cardiovascular responses to sauna remain unclear. This study tested the hypothesis that thermal and cardiovascular responses to sauna are attenuated when CWI was included in a cooling break compared to cooling in air only.

Effects of ceiling fan use on cardiovascular autonomic function during simulated indoor overheating in bed‐resting older adults

Experimental Physiology, EarlyView.
Abstract Older adults are at heightened susceptibility to heat‐related cardiovascular complications when exposed to indoor overheating. While ceiling fans are recommended as an accessible cooling intervention, their effects on cardiac autonomic regulation remain unclear.
