Orthostatic intolerance after spaceflight

Journal of Applied Physiology, 1996
Orthostatic intolerance occurs commonly after spaceflight, and important aspects of the underlying mechanisms remain unclear. We studied 14 individuals supine and standing before and after three space shuttle missions of 9-14 days. After spaceflight, 9 of the 14 (64%) crew members could not complete a 10-min stand test that all completed preflight ...

Orthostatic Intolerance in Children With Long COVID Utilizing a 10-Minute Passive Standing Test

La Clinica pediatrica
Despite there being a wide variety of symptoms reported in pediatric long COVID, one condition that has become increasingly recognized is orthostatic intolerance (OI), which can cause significant morbidity, limiting activities of daily living. This study

Orthostatic intolerance in survivors of childhood cancer

European Journal of Cancer, 2007
To compare the prevalence and severity of orthostatic intolerance in survivors of childhood cancer and in healthy controls, and to correlate results of self-reported measures of health status with orthostatic testing in survivors of childhood cancer.Thirty-nine survivors of childhood cancer and 56 controls were recruited for this study.

Neural autonomic control in orthostatic intolerance

Respiratory Physiology & Neurobiology, 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. Alterations of the neural sympathetic cardiovascular control have been suggested to be one of the potential underlying etiopathogenetic mechanisms in these conditions.

Orthostatic Intolerance: A Disorder of Young Women

Obstetrical & Gynecological Survey, 2000
Orthostatic intolerance (OI) is a cause of significant disability in otherwise healthy women seen by gynecologists. Orthostatic tachycardia is often the most obvious hemodynamic abnormality found in OI patients, but symptoms may include dizziness, visual changes, discomfort in the head or neck, poor concentration, fatigue, palpitations, tremulousness ...

Selected biomarkers of orthostatic intolerance

Vnitřní lékařství, 2023
Orthostatic intolerance (OI) is defined as a group of diseases which symptoms are typically manifested in a standing position. These symptoms result from cerebral hypoperfusion and disappear in the supine position. We include postural orthostatic intolerance syndrome (POTS), orthostatic hypotension (OH) and vasovagal orthostatic syncope in this group ...

Gastrointestinal Symptoms Associated with Orthostatic Intolerance

Journal of Pediatric Gastroenterology and Nutrition, 2005
ABSTRACTBackground:The term orthostatic intolerance is used to describe symptoms of hemodynamic instability such as lightheadedness, fatigue, impaired cognition and syncope that develop on assuming an upright posture. Common forms of orthostatic intolerance in childhood include postural tachycardia syndrome and neurally mediated hypotension.Objective:A
