Testing occurred under two conditions: After normal sleep and after a night shift. VOR gain was measured using the video head impulse test (vHIT) system for both active and passive head movements and for near and far targets. Participants also completed the computerized Dynamic Visual Acuity (c\u2010DVA) test to assess gaze stability and a self\u2010reported vigilance questionnaire.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Participants experienced significantly shorter sleep durations and reported lower vigilance levels on the post\u2010night shift. VOR gain was notably reduced (7.5%) only during passive head movements toward a far target after a night shift. Other vestibular functions, such as distance modulation and other measurements including active head impulses, near\u2010target tests, and c\u2010DVA scores, showed no significant differences between normal sleep and sleep\u2010deprived states.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Sleep deprivation in healthcare night\u2010shift workers demonstrated a complex effect on VOR, with significant impairment in only one specific condition (passive\u2010far). Most other VOR functions, including adaptation to target distance, were maintained. This resilience may indicate an adaptive mechanism within the vestibular system under chronic sleep\u2010deprived conditions, warranting further research into the underlying protective processes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>3<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/lary.32160","type":"journal-article","created":{"date-parts":[[2025,4,2]],"date-time":"2025-04-02T06:02:41Z","timestamp":1743573761000},"page":"3364-3370","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Effect of Sleep Deprivation on the Vestibulo\u2010Ocular Reflex and Vestibular Adaptation in Healthcare Night\u2010Shift Workers"],"prefix":"10.1002","volume":"135","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3601-1724","authenticated-orcid":false,"given":"Nir","family":"Livneh","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery Sheba Medical Center  Tel Hashomer Israel"},{"name":"School of Medicine Tel\u2010Aviv University  Tel Aviv\u2010Yafo Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hadas Ben\u2010rubi","family":"Shimron","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery Sheba Medical Center  Tel Hashomer Israel"},{"name":"Department of Physical Therapy, Faculty of Social Welfare &amp; Health Sciences University of Haifa  Haifa Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3297-7022","authenticated-orcid":false,"given":"Idit","family":"Tessler","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery Sheba Medical Center  Tel Hashomer Israel"},{"name":"School of Medicine Tel\u2010Aviv University  Tel Aviv\u2010Yafo Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2912-2533","authenticated-orcid":false,"given":"Noa","family":"Rozendorn","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery Sheba Medical Center  Tel Hashomer Israel"},{"name":"School of Medicine Tel\u2010Aviv University  Tel Aviv\u2010Yafo Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shibli","family":"Alsleibi","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery Sheba Medical Center  Tel Hashomer Israel"},{"name":"School of Medicine Tel\u2010Aviv University  Tel Aviv\u2010Yafo Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5714-5452","authenticated-orcid":false,"given":"Amit","family":"Wolfovitz","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery Sheba Medical Center  Tel Hashomer Israel"},{"name":"School of Medicine Tel\u2010Aviv University  Tel Aviv\u2010Yafo Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5979-3269","authenticated-orcid":false,"given":"Yoav","family":"Gimmon","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery Sheba Medical Center  Tel Hashomer Israel"},{"name":"Department of Physical Therapy, Faculty of Social Welfare &amp; Health Sciences University of Haifa  Haifa Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,4]]},"reference":[{"key":"e_1_2_7_2_1","volume-title":"Vestibular Rehabilitation","author":"Hain T.
