Abstract

Background and Objective. To explore the effect of respiratory muscle training on children with bronchiectasis. Methods. Participants underwent respiratory muscle training for 24 weeks. The main results were changes in respiratory muscle strength and pulmonary function indices (forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC, peak expiratory flow rate (PEF), forced expiratory flow 25–75% (FEF25–75%), and maximal midexpiratory flow 75/25 (MMEF75/25)) before, 12 weeks after, and 24 weeks after the intervention. The secondary outcomes were changes in the exercise load and work rate, exercise work, Leicester Cough Questionnaire (LCQ) scale, and Fatigue Severity Scale (FSS). Results. Compared with before the intervention, after 24 weeks of respiratory muscle training, the maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were significantly enhanced (P<0.05), while FVC, FEV1, and PEF were significantly increased (P<0.01). FEF25–75 and MMEF75/25 values showed significant improvement compared to those before training (P<0.05). The exercise loading, work, and exercise work rate of expiratory muscle training were significantly improved compared to those before intervention (P<0.05). The LCQ score increased significantly (P< 0.001), and the FSS score decreased significantly (P< 0.001). Conclusion. Incremental load respiratory muscle training effectively improved children’s lung function over the long term, improved the strength of their inspiratory and expiratory muscles, and improved their quality of life.
增量负荷呼吸肌训练可改善支气管扩张症儿童的呼吸肌力量和肺功能
背景和目的。探讨呼吸肌训练对支气管扩张患儿的影响。方法。参与者接受为期 24 周的呼吸肌训练。主要结果为干预前、干预后 12 周和干预后 24 周呼吸肌力量和肺功能指数(1 秒用力呼气容积 (FEV1)、用力肺活量 (FVC)、FEV1/FVC、呼气峰流速 (PEF)、25-75% 用力呼气流量 (FEF25-75%) 和最大侧吸气流量 75/25 (MMEF75/25))的变化。次要结果是运动负荷和工作率、运动工作、莱斯特咳嗽问卷(LCQ)量表和疲劳严重程度量表(FSS)的变化。结果显示与干预前相比,经过 24 周的呼吸肌训练后,最大吸气压(MIP)和最大呼气压(MEP)显著提高(P<0.05),而 FVC、FEV1 和 PEF 显著增加(P<0.01)。与训练前相比,FEF25-75 和 MMEF75/25 值有明显改善(P<0.05)。与干预前相比,呼气肌训练的运动负荷、运动功和运动功率均有明显改善(P<0.05)。LCQ评分明显上升(P< 0.001),FSS评分明显下降(P< 0.001)。结论增量负荷呼吸肌训练长期有效地改善了儿童的肺功能,提高了他们吸气和呼气肌肉的力量,改善了他们的生活质量。
