People with type 2 diabetes mellitus present multiple complications and comorbidities, such as peripheral autonomic neuropathies and reduced peripheral force and functional capacity. Inspiratory muscle training is a widely used intervention with numerous benefits for various disorders. The present study aimed to conduct a systematic review to identify inspiratory muscle training effects on functional capacity, autonomic function, and glycemic indexes in patients with type 2 diabetes mellitus.
A search was carried out by two independent reviewers. It was performed in PubMed®, Cochrane Library, Latin American and Caribbean Literature in Health Sciences (or LILACS), Physiotherapy Evidence Database (PEDro), Embase, Scopus, and Web of Science databases. There were no restrictions of language or time. Randomized clinical trials of type 2 diabetes mellitus with inspiratory muscle training intervention were selected. Studies' methodological quality was assessed using PEDro scale.
We found 5,319 studies, and six were selected for qualitative analysis, which was also conducted by the two reviewers. Methodological quality varied - two studies were classified as high quality, two as moderate quality, and two as low quality.
It was found that after inspiratory muscle training protocols, there was a reduction in the sympathetic modulation and an increase in functional capacity. The results should be carefully interpreted, as there were divergences in the methodologies adopted, populations, and conclusions between the studies evaluated in this review.
2 型糖尿病患者会出现多种并发症和合并症，如周围自主神经病变以及外周肌力和功能能力降低。吸气肌训练是一种广泛应用的干预措施，对多种疾病均有益处。本研究旨在进行系统评价，以确定吸气肌训练对 2 型糖尿病患者的功能能力、自主神经功能和血糖指数的影响。
两名独立评审员进行了检索。检索了 PubMed®、Cochrane 图书馆、拉丁美洲和加勒比健康科学文献（或 LILACS）、物理治疗证据数据库（PEDro）、Embase、Scopus 和 Web of Science 数据库。未对语言或时间进行限制。选择了有 2 型糖尿病吸气肌训练干预的随机临床试验。使用 PEDro 量表评估研究的方法学质量。
我们发现了 5319 项研究，其中 6 项被选中进行定性分析，这也是由两位评审员进行的。方法学质量各不相同——两项研究被评为高质量，两项为中等质量，两项为低质量。
研究发现，在进行吸气肌训练方案后，交感神经调节得到降低，功能能力得到提高。应仔细解释结果，因为在本次评价的研究中，所采用的方法、人群和结论存在差异。
