Abstract

Inspiratory muscle training (IMT) is used across various pathology domains to improve respiratory function. Limited literature exists which demonstrates IMT benefit among patients with Diaphragmatic dysfunction. 7 individuals with a mean age of 59.6yrs had unilateral diaphragmatic dysfunction (UDD) post cardiac surgery and were referred to a cardiac rehab program where an IMT strength based protocol was prescribed. IMT implementation over an average of 13 weeks yielded an average improvement in maximum inspiratory pressure (MIP) of 48 % (p value 0.018), peak inspiratory flow rate (PIFR) of 45 % (p value 0.018), forced expired volume in 1 sec (FEV1) of 15 % (p value 0.028) and forced vital capacity (FVC) of 15 % (p value 0.018). This case series of data adds to the limited evidence that exists currently and outlines the benefits of IMT application within unilateral diaphragmatic dysfunction.

治疗膈肌功能障碍的吸气肌肉训练：病例系列

吸气肌训练（IMT）用于各种病理领域，以改善呼吸功能。证明吸气肌训练对膈肌功能障碍患者有益的文献有限。7 名平均年龄为 59.6 岁的患者在心脏手术后出现单侧膈肌功能障碍 (UDD)，他们被转介到一个心脏康复项目，该项目规定了基于 IMT 力量的方案。在平均 13 周的时间里，IMT 的实施使最大吸气压力 (MIP) 平均提高了 48%（P 值为 0.018），吸气峰流速 (PIFR) 平均提高了 45%（P 值为 0.018），1 秒内用力呼气容积 (FEV1) 平均提高了 15%（P 值为 0.028），用力呼吸容量 (FVC) 平均提高了 15%（P 值为 0.018）。这组病例数据补充了目前存在的有限证据，并概述了在单侧膈肌功能障碍中应用 IMT 的益处。
