This study examines rates of OI in 92 children with long COVID who underwent a bedside passive standing test in a pediatric post-COVID-19 rehabilitation clinic. Seventy-one percent met criteria for an orthostatic condition, including postural orthostatic tachycardia syndrome (POTS), orthostatic tachycardia (OT), classic orthostatic hypotension (OH), delayed OH, and orthostatic hypertension. Our findings suggest that OI is common in pediatric long COVID, necessitating appropriate clinical screening and treatment.<\/jats:p>","DOI":"10.1177\/00099228241272053","type":"journal-article","created":{"date-parts":[[2024,8,10]],"date-time":"2024-08-10T00:25:45Z","timestamp":1723249545000},"page":"416-424","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Orthostatic Intolerance in Children With Long COVID Utilizing a 10-Minute Passive Standing Test"],"prefix":"10.1177","volume":"64","author":[{"given":"Amanda K.","family":"Morrow","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Johns Hopkins University School of Medicine, Baltimore, MD, USA"},{"name":"Kennedy Krieger Institute, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cindy","family":"Villatoro","sequence":"additional","affiliation":[{"name":"Kennedy Krieger Institute, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6486-4391","authenticated-orcid":false,"given":"Christina","family":"Kokorelis","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Johns Hopkins University School of Medicine, Baltimore, MD, USA"},{"name":"Kennedy Krieger Institute, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter C.","family":"Rowe","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Johns Hopkins University School of Medicine, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9836-822X","authenticated-orcid":false,"given":"Laura A.","family":"Malone","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Johns Hopkins University School of Medicine, Baltimore, MD, USA"},{"name":"Kennedy Krieger Institute, Baltimore, MD, USA"},{"name":"Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,8,9]]},"reference":[{"key":"e_1_3_2_2_2","unstructured":"Children and COVID-19: State-Level Data Report.
