The Clinical Utility of Assessing Orthostatic Intolerance in Adolescents with Sport-Related Concussion, a Retrospective Study [PDF]

Diagnostics
Background/Objective: Assessing Orthostatic Intolerance (OI, symptoms upon standing from supine) is recommended in athletes with sport-related concussions (SRCs), as this is caused by impairments in the cardiovascular autonomic nervous system (cANS ...

Detecting Orthostatic Intolerance in Long COVID in a Clinic Setting. [PDF]

Int J Environ Res Public Health, 2023
Introduction: A likely mechanism of Long COVID (LC) is dysautonomia, manifesting as orthostatic intolerance (OI). In our LC service, all patients underwent a National Aeronautics and Space Administration (NASA) Lean Test (NLT), which can detect OI ...

Orthostatic Intolerance in Older Persons: Etiology and Countermeasures [PDF]

Frontiers in Physiology, 2017
Orthostatic challenge produced by upright posture may lead to syncope if the cardiovascular system is unable to maintain adequate brain perfusion. This review outlines orthostatic intolerance related to the aging process, long-term bedrest confinement ...

Orthostatic Intolerance in Long-Haul COVID after SARS-CoV-2: A Case-Control Comparison with Post-EBV and Insidious-Onset Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Patients [PDF]

Healthcare, 2022
Background: As complaints of long-haul COVID patients are similar to those of ME/CFS patients and as orthostatic intolerance (OI) plays an important role in the COVID infection symptomatology, we compared 14 long-haul COVID patients with 14 ME/CFS ...

Physiological assessment of orthostatic intolerance in chronic fatigue syndrome. [PDF]

J Transl Med, 2022
Background Orthostatic intolerance-OI is common in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome-ME/CFS. We used a 10-min passive vertical lean test as orthostatic challenge-OC and measured changes in vitals and end tidal CO 2 (eTCO2).

Case report: Recurrent cervical spinal stenosis masquerading as myalgic encephalomyelitis/chronic fatigue syndrome with orthostatic intolerance [PDF]

Frontiers in Neurology, 2023
IntroductionMyalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex, chronic, multi-system disorder that is characterized by a substantial impairment in the activities that were well tolerated before the illness. In an earlier report, we

Pediatric Disorders of Orthostatic Intolerance [PDF]

Pediatrics, 2018
Orthostatic intolerance (OI), having difficulty tolerating an upright posture because of symptoms or signs that abate when returned to supine, is common in pediatrics. For example, ∼40% of people faint during their lives, half of whom faint during adolescence, and the peak age for first faint is 15 years.

Orthostatic intolerance during early mobilization following thoracoscopic lung resection: a prospective observational study [PDF]

BMC Surgery
Background Early postoperative mobilization is important for enhanced recovery but can be hindered by orthostatic intolerance. However, study on postoperative orthostatic intolerance in thoracoscopic lung resection is limited.
