Abstract

PURPOSE The aim of this study is to assess the effects of respiratory exercises (inspiratory and expiratory) in individuals with sleep bruxism (SB) and associated obstructive sleep apnea (OSA). METHODS This is a double-blind, placebo-controlled randomized clinical trial including individuals with SB and associated respiratory events in OSA. Respiratory physical therapy was performed using inspiratory (Threshold® IMT), expiratory (Threshold® 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. RESULTS Awakening was significantly different (p ≤ 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 ≤ 0.05). CONCLUSION Respiratory physical therapy for OSA improved awaking levels in 80 and 67% of the number of masseter muscle contractions, when compared to placebo. TRIAL REGISTRATION Brazilian Registry of Clinical Trials (No. RBR-9F6JKM).

呼吸训练对睡眠磨牙症和相关阻塞性睡眠呼吸暂停的影响：一项双盲、安慰剂对照随机临床试验。

目的本研究旨在评估呼吸训练（吸气和呼气）对睡眠磨牙症（SB）和相关阻塞性睡眠呼吸暂停（OSA）患者的影响。方法这是一项双盲、安慰剂对照随机临床试验，研究对象包括睡眠磨牙症（SB）和相关 OSA 呼吸事件患者。采用吸气（Threshold® IMT）、呼气（Threshold® PEP）肌肉训练进行呼吸理疗，并与安慰剂组进行比较。每天共进行 30 次呼吸循环（吸气和呼气），每周 5 次，持续 12 周。通过匹兹堡睡眠质量指数和多导睡眠图，分别在基线（T1）和训练 12 周后（T2）对患者进行两次重新评估。吸气组、呼气组和安慰剂组的颌下肌收缩次数存在差异（P≤0.05）。结论与安慰剂相比，呼吸理疗治疗 OSA 可改善 80% 的觉醒水平和 67% 的颌下肌收缩次数。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
