Inclusion Body Myositis (IBM) is the most common acquired myopathy in older individuals with more than two thirds of patients experiencing impaired swallowing. There are currently no standardized exercise therapies to improve or sustain swallowing despite good evidence for exercise therapy in limb muscles. Reduced upper esophageal sphincter opening is a common abnormality associated with dysphagia in IBM. This pilot study recruited IBM patients with abnormal upper esophageal sphincter function and dysphagia into an exercise program. It was hypothesized that regular practice using the Expiratory Muscle Strength Trainer (EMST) device would improve hyolaryngeal movement by strengthening suprahyoid musculature and facilitate opening of the upper esophageal sphincter thereby improving swallowing and quality of life. Overall, IBM patients who used the EMST device demonstrated no improvement in swallowing function. Consistent with that result, there was also no change in measures of quality of life. However, further studies are needed to elucidate whether it has a preventative role in the development or progression of dysphagia in IBM as there is a suggestion that patients with a shorter duration of disease may have had some benefit. This research provides pilot data and recommendations that will guide future studies on exercise therapy and swallowing in this area.

探索呼气肌力量训练器改善包涵体肌炎吞咽的功效：一项初步研究

包涵体肌炎 (IBM) 是老年人中最常见的获得性肌病，超过三分之二的患者吞咽受损。尽管肢体肌肉运动疗法有很好的证据，但目前没有标准化的运动疗法来改善或维持吞咽。上食管括约肌开口减少是 IBM 中与吞咽困难相关的常见异常。这项初步研究招募了上食管括约肌功能异常和吞咽困难的 IBM 患者参加锻炼计划。据推测，使用呼气肌肉力量训练器 (EMST) 设备的定期练习将通过加强舌骨上肌组织和促进上食管括约肌的开放来改善喉部运动，从而改善吞咽和生活质量。全面的，使用 EMST 设备的 IBM 患者在吞咽功能方面没有表现出任何改善。与该结果一致，生活质量指标也没有变化。然而，需要进一步的研究来阐明它是否对 IBM 吞咽困难的发展或进展具有预防作用，因为有迹象表明疾病持续时间较短的患者可能有一些益处。这项研究提供了试点数据和建议，将指导该领域未来关于运动疗法和吞咽的研究。需要进一步的研究来阐明它是否在 IBM 吞咽困难的发展或进展中具有预防作用，因为有迹象表明疾病持续时间较短的患者可能有一些益处。这项研究提供了试点数据和建议，将指导该领域未来关于运动疗法和吞咽的研究。需要进一步的研究来阐明它是否在 IBM 吞咽困难的发展或进展中具有预防作用，因为有迹象表明疾病持续时间较短的患者可能有一些益处。这项研究提供了试点数据和建议，将指导该领域未来关于运动疗法和吞咽的研究。
