We aimed to evaluate and compare RME in subjects with OHS and a control group using an incremental load test and compare the RME of subjects with OHS in whom noninvasive ventilation (NIV) was and was not used.<\/jats:p>\n <\/jats:sec>\n \n METHODS:<\/jats:title>\n \n Forty subjects with OHS (divided according to body mass index [BMI] as group I: 30\u201340 kg\/m\n 2<\/jats:sup>\n ; and group II: \u2265 40 kg\/m\n 2<\/jats:sup>\n ) and 20 subjects with obesity (control group: 30\u201340 kg\/m\n 2<\/jats:sup>\n ) were included in the study. RME was evaluated using the incremental load test, and respiratory muscle strength (RMS) was evaluated using mouth pressure measurements. The 6-min walk test, Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), EQ-5D Health-Related Quality of Life Questionnaire (EQ-5D), and the Obesity and Weight-Loss Quality of Life Instrument (OWLQOL) were performed.\n <\/jats:p>\n <\/jats:sec>\n \n RESULTS:<\/jats:title>\n \n RME and RMS (%) in group I were lower than the control group (\n P<\/jats:italic>\n = .001,\n P<\/jats:italic>\n = .005, and\n P<\/jats:italic>\n = .001, respectively). No significant difference was found between the 3 groups in terms of 6-min walk distance (6MWD) percentage predicted values (\n P<\/jats:italic>\n = .98). RME in the NIV user group was higher than the non-user group (\n P<\/jats:italic>\n = .006). ESS, total PSQI, and FSS scores in the control group were less than group I (\n P<\/jats:italic>\n = .01,\n P<\/jats:italic>\n = .009, and\n P<\/jats:italic>\n = .005, respectively) and group II (\n P<\/jats:italic>\n = .01,\n P<\/jats:italic>\n < .001, and\n P<\/jats:italic>\n < .001, respectively). The EQ-5D scores of the control group were higher than group II only (\n P<\/jats:italic>\n = .005 and\n P<\/jats:italic>\n = .005, respectively). There were no differences in OWLQOL between the groups (\n P<\/jats:italic>\n = .053).\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS:<\/jats:title>\n RME was low in subjects with OHS but higher in those who used NIV. The incremental load test could be performed easily and safely in a clinic setting.<\/jats:p>\n <\/jats:sec>","DOI":"10.4187\/respcare.09338","type":"journal-article","created":{"date-parts":[[2022,3,22]],"date-time":"2022-03-22T11:05:14Z","timestamp":1647947114000},"page":"526-533","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Respiratory Muscle Endurance in Obesity Hypoventilation Syndrome"],"prefix":"10.1177","volume":"67","author":[{"given":"Elif Sena","family":"Dusgun","sequence":"first","affiliation":[{"name":"Fenerbahce University, Vocational School of Health Sciences, Department of Physiotherapy, Istanbul, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Goksen Kuran","family":"Aslan","sequence":"additional","affiliation":[{"name":"Istanbul University-Cerrahpasa, Faculty of Health Sciences, Division of Physiotherapy and Rehabilitation, Istanbul, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ebru Seker","family":"Abanoz","sequence":"additional","affiliation":[{"name":"Istanbul University-Cerrahpasa, Institute of Graduate Studies, Division of Physiotherapy and Rehabilitation, Istanbul, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Esen","family":"Kiyan","sequence":"additional","affiliation":[{"name":"Istanbul University, Istanbul Faculty of Medicine, Department of Chest Diseases, Istanbul, Turkey."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,3,22]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1183\/16000617.0097-2018"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1513\/pats.200708-122MG"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000441-200104000-00006"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjmed.2005.03.042"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.01157.2007"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.95.1.90"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.166.4.518"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.97.10122868"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00095406"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0170696"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/pri.1687"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1378\/chest.119.4.1102"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.5664\/JCSM.1308"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.01214-2018"},{"issue":"5","key":"e_1_3_3_16_2","first-page":"696","article-title":"Maximal respiratory pressures: normal values and relationship to age and sex","volume":"99","author":"Black LF","year":"1969","unstructured":"Black LF, , Hyatt RE.
