Fibromyalgia syndrome (FM) is a complex disease that is mainly characterised by chronic pain, fatigue, and sleep disturbances and may be precipitated or worsened by many stressors. The aim of this study was to examine the effects of respiratory muscle training (RMT) on respiratory efficiency and health-related quality of life (HRQoL) in women with FM.
A total of 30 women with FM were included in the intention to treat analyses: 15 were assigned to the RMT group and 15 to the control group. The intervention consisted of 12 weeks of RMT. The primary outcome was the change in pulmonary function assessed by global body plethysmography at 12 weeks compared with baseline. Secondary outcomes included changes of scores in HRQoL assessed by the Short Form 36 Health Survey-Portuguese version.
The maximal inspiratory pressure (MIP) improved by 17.5% (p-value = .033), maximal expiratory pressure (MEP) improved 21.6% (p-value = 0.045) and maximum occlusion pressure (P0.1 max) increased 27.7% (p-value = 0.007). HRQoL improved in the dimensions of physical function, physical role, bodily pain and vitality (p-value <0.05).
RMT results in a significant improvement of respiratory efficiency and HRQoL after 12 weeks. RMT could be an effective therapy to enhance respiratory function and quality of life in women with FM.
纤维肌痛综合征（FM）是一种复杂的疾病，主要表现为慢性疼痛、疲劳和睡眠障碍，并且可能由许多应激源引发或加重。本研究的目的是研究呼吸肌训练（RMT）对 FM 女性呼吸效率和健康相关生活质量（HRQoL）的影响。
共有 30 名 FM 女性被纳入意向治疗分析：15 名被分配到 RMT 组，15 名被分配到对照组。干预措施包括 12 周的 RMT。主要结局是通过全身体积描记术在 12 周时评估的肺功能变化与基线相比。次要结局包括通过 36 项简短健康调查-葡萄牙语版本评估的 HRQoL 评分的变化。
最大吸气压力（MIP）提高了 17.5%（p 值=0.033），最大呼气压力（MEP）提高了 21.6%（p 值=0.045），最大闭塞压力（P0.1 max）增加了 27.7%（p 值=0.007）。HRQoL 在身体功能、身体角色、身体疼痛和活力方面有所改善（p 值<0.05）。
RMT 在 12 周后可显著改善呼吸效率和 HRQoL。RMT 可能是增强 FM 女性呼吸功能和生活质量的有效治疗方法。
