A positional therapy device placed at the forehead has proven to be effective in reducing the severity of positional obstructive sleep apnoea (POSA) symptoms. The aim of the study was to evaluate patients\u2019 therapy compliance and satisfaction in the short term and mid-term.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>A post hoc analysis of a randomised controlled trial was conducted using an inactive device (ID) or an active device (AD) for 3 months. The primary outcomes were device usage and the percentage of patients with good compliance (defined as device use for more than 4\u2009hours per night and more than 70% of nights per week). Secondary outcomes included time spent with head in the supine position, patient satisfaction and side effects.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The median duration of using the device was 6.9\u2009hours in the ID group and 6.7\u2009hours in the AD group (p=0.309), and the durations were similar throughout the follow-up period and from the first day of use. The percentage of patients with good compliance was similar and greater than 60% in both groups. The median time spent with head in the supine position was significantly lower in the AD group (2.9%) than in the ID group (12.4%) since the first day of treatment. Both groups showed satisfaction scores values above 8.5 (out of 10) in all items, while side effects were scarcely reported.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>High device compliance was achieved in POSA patients, both in terms of device usage time and percentage of days used. Patients were highly satisfied, and the device effectively reduced the time spent with the head in the supine position from the first day of use.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/bmjresp-2022-001503","type":"journal-article","created":{"date-parts":[[2023,6,23]],"date-time":"2023-06-23T09:34:59Z","timestamp":1687512899000},"page":"e001503","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Patient compliance and satisfaction with a new forehead device for positional obstructive sleep apnoea treatment: a post hoc analysis of a randomised controlled trial"],"prefix":"10.1136","volume":"10","clinical-trial-number":[{"clinical-trial-number":"nct03336515","registry":"10.18810\/clinical-trials-gov"}],"author":[{"given":"Laura","family":"Hidalgo-Armas","sequence":"first","affiliation":[{"name":"Sleep Disorders Research Group, Bioaraba Health Research Institute, Vitoria, Spain"},{"name":"Alava Mental Health Network, Osakidetza Basque Health Service, Vitoria, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Ingl\u00e9s","sequence":"additional","affiliation":[{"name":"Sleep Disorders Research Group, Bioaraba Health Research Institute, Vitoria, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafaela","family":"Vaca","sequence":"additional","affiliation":[{"name":"CIBER of Respiratory Diseases (CibeRes), ISCIII, Madrid, Spain"},{"name":"Translational Research in Respiratory Medicine, IRB Lleida, Lleida, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9","family":"Cordero-Guevara","sequence":"additional","affiliation":[{"name":"Epidemiology and Public Health Research Group, Bioaraba Health Research Institute, Vitoria-Gasteiz, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaqu\u00edn","family":"Dur\u00e1n-Carro","sequence":"additional","affiliation":[{"name":"Sleep Disorders Research Group, Bioaraba Health Research Institute, Vitoria, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1087-1232","authenticated-orcid":false,"given":"Jorge","family":"Ullate","sequence":"additional","affiliation":[{"name":"Sleep Disorders Research Group, Bioaraba Health Research Institute, Vitoria, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jordi","family":"Rigau","sequence":"additional","affiliation":[{"name":"Research, Development and Innovation Director, SIBEL S.A.U, Barcelona, Spain"},{"name":"Biophysics and Bioengineering Unit, School of Medicine Barcelona, University of Barcelona, Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaquin","family":"Dur\u00e1n-Cantolla","sequence":"additional","affiliation":[{"name":"Honorific Professor of the Medicine Department, UPV\/EHU School of Medicine, Vitoria, Spain"},{"name":"Director of the Eduardo Anitua Medical Clinic Sleep Unit, Eduardo Anitua Medical Clinic Sleep Unit, Vitoria, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,6,22]]},"reference":[{"key":"2025083112311144000_10.1.e001503.1","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.5664\/jcsm.8664","article-title":"Efficacy and long-term follow-up of Positional therapy by Vibrotactile neck-based device in the management of Positional OSA","volume":"16","author":"De Corso","year":"2020","journal-title":"J Clin Sleep Med"},{"key":"2025083112311144000_10.1.e001503.2","doi-asserted-by":"crossref","first-page":"821","DOI":"10.1007\/s11325-017-1525-2","article-title":"Influence of head position on obstructive sleep apnea severity","volume":"21","author":"Zhu","year":"2017","journal-title":"Sleep Breath"},{"key":"2025083112311144000_10.1.e001503.3","doi-asserted-by":"crossref","first-page":"111","DOI":"10.1016\/j.rmed.2019.02.005","article-title":"A new postural device for the treatment of Positional obstructive sleep apnea.
