【摘要】：目的 :探讨长期吸气肌阻力训练(inspiratory muscle training,IMT)对稳定期慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)患者呼吸肌肌力、呼吸困难和生活质量的影响。方法 :2012年5月—2013年2月,按照随机数字表将符合条件的71例稳定期COPD患者分为实验组即最大阈值负荷(最大吸气压60%)IMT训练组和对照组即低负荷(9 cm H2O)IMT训练组,均用Threshold AC0043型阻力训练器训练1年,每周6 d,每天早晚各15 min。结果:1年后63例患者完成随访,其中实验组和对照组分别退出3例和5例。各组干预前后最大吸气压和生活质量SGRQ问卷呼吸症状、活动能力和疾病影响评分比较,差异均有统计学意义(P0.05)。干预后两组患者的最大吸气压和SGRQ活动能力评分差异均有统计学意义(P0.05),而肺功能差异无统计学意义。结论:1年最大负荷量的IMT可以显著提高稳定期COPD患者的吸气肌力和生活质量,然而肺功能改善不显著。
[Abstract]:Objective: to investigate the effects of long-term inspiratory muscle resistance training (inspiratory muscle training,IMT) on respiratory muscle strength, dyspnea and quality of life (QOL) in patients with stable chronic obstructive pulmonary disease (chronic obstructive pulmonary disease,COPD). Methods: may 2012-February 2013, According to the random number table, 71 patients with stable COPD were divided into experimental group (maximum threshold load (maximum suction pressure) 60%) IMT training group and control group (9 cm H2O) IMT training group. All of them were trained with Threshold AC0043 resistance trainer for 1 year, 6 days a week, 15 min. in the morning and evening. Results: 63 patients were followed-up one year later, including 3 cases in the experimental group and 5 cases in the control group. Before and after intervention, the maximal suction pressure and quality of life (SGRQ) questionnaire respiratory symptoms, activity and disease impact scores, the differences were statistically significant (P0.05). After intervention, there were significant differences in maximal suction pressure and SGRQ activity score between the two groups (P0.05), but there was no significant difference in pulmonary function between the two groups. Conclusion: 1 year maximum load IMT can significantly improve inspiratory muscle strength and quality of life in patients with stable COPD, but the improvement of pulmonary function is not significant.
