The objective of this study was to determine whether eye-blinks could be elicited by electrical stimulation and whether electrically induced blink would have an effect on the visual acuity and ocular symptoms in patients with acute facial nerve palsy. Methods: The zygomatic branch of the facial nerve of fifteen participants with acute facial nerve palsy was electrically stimulated in order to elicit a blink. In successful cases, the participant proceeded with a two-hour TV watching session in which an electrically induced blink was delivered every 5\u00a0seconds. The control condition consisted of an otherwise similar TV watching session without electrically induced blinking. Subjective ocular symptoms were evaluated with a Dry Eye Questionnaire and visual acuity was assessed with a Logarithm of the Minimum Angle of Resolution (LogMAR) chart before and after both sessions. Results: The stimulation produced a blink in 8 participants (53%). The visual acuity in the affected eye decreased during the control session, whereas no significant change occurred during the stimulation session. The ocular symptoms were significantly reduced during the stimulation session. Conclusions: Electrically elicited blink is a promising method for reducing the eye symptoms in individuals with acute facial nerve palsy.<\/jats:p>","DOI":"10.1177\/01455613211048576","type":"journal-article","created":{"date-parts":[[2021,10,29]],"date-time":"2021-10-29T10:40:30Z","timestamp":1635504030000},"page":"NP294-NP300","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["Electrically Induced Blink for the Prevention of Ocular Symptoms and Blurred Vision in Patients With Acute Facial Nerve Palsy"],"prefix":"10.1177","volume":"103","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8924-0331","authenticated-orcid":false,"given":"Eeva","family":"M\u00e4kel\u00e4","sequence":"first","affiliation":[{"name":"Department of Clinical Neurophysiology, Tampere University Hospital, Tampere, Finland"},{"name":"Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanna","family":"Venesvirta","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirja","family":"Ilves","sequence":"additional","affiliation":[{"name":"Research Group for Emotions, Sociality, and Computing, Faculty of Information Technology and Communication Sciences, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jani","family":"Lylykangas","sequence":"additional","affiliation":[{"name":"Research Group for Emotions, Sociality, and Computing, Faculty of Information Technology and Communication Sciences, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ville","family":"Rantanen","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hannu","family":"Uusitalo","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland"},{"name":"Department of Ophthalmology, Tampere University Hospital, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jarmo","family":"Verho","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antti","family":"Vehkaoja","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jukka","family":"Lekkala","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veikko","family":"Surakka","sequence":"additional","affiliation":[{"name":"Research Group for Emotions, Sociality, and Computing, Faculty of Information Technology and Communication Sciences, Tampere University, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Rautiainen","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Technology, Tampere University, Tampere, Finland"},{"name":"Department of Otorhinolaryngology, Tampere University Hospital, Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,10,29]]},"reference":[{"key":"bibr1-01455613211048576","doi-asserted-by":"publisher","DOI":"10.1080\/000164802760370736"},{"key":"bibr2-01455613211048576","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa072006"},{"key":"bibr3-01455613211048576","doi-asserted-by":"publisher","DOI":"10.1038\/sj.eye.6701383"},{"key":"bibr4-01455613211048576","doi-asserted-by":"publisher","DOI":"10.1002\/micr.1050"},{"key":"bibr5-01455613211048576","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2007.891372"},{"key":"bibr6-01455613211048576","doi-asserted-by":"publisher","DOI":"10.1109\/TBCAS.2013.2255051"},{"key":"bibr7-01455613211048576","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-015-3884-2"},{"key":"bibr8-01455613211048576","doi-asserted-by":"publisher","DOI":"10.1177\/0194599811427255"},{"key":"bibr9-01455613211048576","volume-title":"EMBEC & NBC 2017.
