This pilot study was designed to determine if mouthpiece NIV (M-NIV) alters speech in individuals with muscular dystrophy (MD).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Method<\/jats:title>\n            <jats:p>\n              Eight men (23\u201344 years), seven with Duchenne MD and one with Becker MD, who used daytime M-NIV, were asked to sustain phonation, count, and read under three conditions: (a)\n              <jats:italic>Uncued<\/jats:italic>\n              (no instructions), (b)\n              <jats:italic>With M-NIV<\/jats:italic>\n              (cued to use M-NIV with all speaking breaths), and (c)\n              <jats:italic>Without M-NIV<\/jats:italic>\n              (as tolerated). Breath group and inspiratory durations, syllables\/breath group, and relative sound pressure level were determined from audio and video recordings.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Uncued condition: Participants used the ventilator for all inspirations that preceded sustained phonation and counting. During reading, four participants used M-NIV for all inspirations, one never used it, and three used it for some (19%\u201341%) inspirations.<\/jats:p>\n            <jats:p>With- versus Without-M-NIV conditions: Breath group duration was significantly longer across all tasks, syllables per breath group were significantly greater during reading, and inspiratory pause duration during reading was significantly longer with M-NIV than without. Sound pressure level was significantly higher during the first second of sustained phonation with M-NIV (though not for counting and reading). Two participants were unable to complete the reading task audibly without using their M-NIV.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Speech may be better with M-NIV than without because it is possible to produce longer breath groups and some people with severe respiratory muscle weakness may not be able to speak at all without ventilator-supplied air. Nevertheless, the longer inspiratory pauses that accompany M-NIV may interrupt the flow of speech. Future research is needed to determine the most effective way to use M-NIV for speaking and whether training participants in its use can bring even greater speech benefits.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1044\/2020_ajslp-20-00146","type":"journal-article","created":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T00:00:52Z","timestamp":1614729652000},"page":"1373-1381","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Mouthpiece Noninvasive Ventilation on Speech in Men With Muscular Dystrophy: A Pilot Study"],"prefix":"10.1044","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8771-2654","authenticated-orcid":false,"given":"Deanna","family":"Britton","sequence":"first","affiliation":[{"name":"Department of Speech and Hearing Sciences, Portland State University, OR"},{"name":"Northwest Center for Voice and Swallowing, Department of Otolaryngology\u2014Head and Neck Surgery, Oregon Health and Science University, Portland"},{"name":"Department of Rehabilitation Medicine, University of Washington Medical Center, Seattle"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Pullen","sequence":"additional","affiliation":[{"name":"Not Only Words Therapy, Mesa, AZ"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeannette D.","family":"Hoit","sequence":"additional","affiliation":[{"name":"Department of Speech, Language and Hearing Sciences, University of Arizona, Tucson"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joshua O.","family":"Benditt","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, University of Washington Medical Center, Seattle"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1310","reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.104.6.1702"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.4187\/respcare.00831"},{"key":"e_1_3_2_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/PHM.0000000000000228"},{"key":"e_1_3_2_5_1","doi-asserted-by":"publisher","DOI":"10.1044\/1092-4388(2002\/007)"},{"key":"e_1_3_2_6_1","volume-title":"Speech powered by mouthpiece positive-pressure inspirations in neuromuscular disease","author":"Bareiss I.
