Screening for Orthostatic Intolerance in Symptomatic Children Presenting for Concussion Care
La Clinica pediatrica, 2020Following concussion, children often experience nonspecific symptoms that overlap with those of other common pediatric conditions, including orthostatic intolerance (OI).

Abstract A goal of the previous chapters was to explain how neural and humoral mechanisms of vascular and cardiac control keep blood pressure from falling during orthostasis. The goal of this chapter is to amplify the discussion of essential adjustments to orthostasis by showing what happens when a particular part of the control system ...

Gastrointestinal Symptoms Associated with Orthostatic Intolerance
Journal of Pediatric Gastroenterology and Nutrition, 2005ABSTRACTBackground: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

Dynamic Countermeasure Fabrics for Post-Spaceflight Orthostatic Intolerance.
Aerospace Medicine and Human Performance, 2020INTRODUCTION: Aerospace orthostatic intolerance garments (OIG) have historically been pneumatic (e.g., NASA's antigravity suit), an approach that inhibits mobility and requires connection to an air supply.

Orthostatic intolerance and orthostatic tachycardia: A heterogeneous disorder
Clinical Autonomic Research, 1995A series of autonomic function tests were performed in eight patients who had orthostatic intolerance and orthostatic tachycardia (> 36 bpm). All eight had an abnormal tilt-table test (mean tachycardia 50 bpm compared with 22 +/- 7 bpm in 31 normal subjects). Plasma volume was low in four out of six patients.

Orthostatic Intolerance and the Headache Patient
Seminars in Pediatric Neurology, 2010Orthostatic intolerance (OI) refers to a group of clinical conditions, including postural orthostatic tachycardia syndrome (POTS) and neurally mediated hypotension (NMH), in which symptoms worsen with upright posture and are ameliorated by recumbence.

Orthostatic Intolerance: Orthostatic Hypotension and Postural Orthostatic Tachycardia Syndrome
2010In health, movement from lying or sitting to standing is largely unassociated with evident change in well-being. However, in some individuals, especially those who are physically deconditioned, there may be a transient sense of increased heart rate.

Neural autonomic control in orthostatic intolerance
Respiratory Physiology & Neurobiology, 2009Inability 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: orthostatic hypotension and postural orthostatic tachycardia syndrome
2018The impairment of adaptive mechanisms during orthostatic challenge may evoke orthostatic intolerance, a heterogeneous condition, in which the standing position elicits a fall in blood pressure and/or excessive tachycardia, accompanied by a wide spectrum of subjective symptoms such as dizziness, discomfort, nausea, and palpitations.
