Respiratory physical therapy was performed using inspiratory (Threshold\u00ae IMT), expiratory (Threshold\u00ae PEP) muscle training, and compared with a placebo group. A total of 30 daily respiratory cycles (inspiration and expiration) were performed five times a week for 12 weeks. Individuals were reassessed at two times, at baseline (T1) and after 12 weeks of training (T2) by means of the Pittsburgh Sleep Quality Index and Polysomnography.\nResults: Awakening was significantly different (p \u2264 0.05) between the inspiratory group and placebo 12 weeks after respiratory physical therapy. The number of contractions of the masseter muscle differed between the inspiratory, expiratory, and placebo groups (p \u2264 0.05).\nConclusion: Respiratory physical therapy for OSA improved awaking levels in 80 and 67% of the number of masseter muscle contractions, when compared to placebo.\nTrial registration: Brazilian Registry of Clinical Trials (No. RBR-9F6JKM)<\/jats:p>","DOI":"10.2340\/aos.v83.40252","type":"journal-article","created":{"date-parts":[[2024,4,5]],"date-time":"2024-04-05T13:35:22Z","timestamp":1712324122000},"page":"120-125","source":"Crossref","is-referenced-by-count":2,"title":["Effects of respiratory exercises in sleep bruxism and associated obstructive sleep apnea: a double-blind, placebo-controlled randomized clinical trial"],"prefix":"10.2340","author":[{"given":"Bianca Lopes","family":"Cavalcante-Leao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9 Lu\u00eds","family":"Porporatti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosa","family":"C\u00edntia Felicio Adriano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosane Sampaio","family":"Santos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Isabel","family":"Vanelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabella","family":"Perez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristiano","family":"Miranda de Ara\u00fajo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Stechman-Neto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bianca Simone","family":"Zeigelboim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2024,4,5]]},"reference":[{"key":"55189","doi-asserted-by":"crossref","unstructured":"Lobbezoo J, Ahlberg KG, Raphael P, et al.
