慢性阻塞性肺疾病稳定期患者呼吸肌网络训练系统的应用研究

摘要

Objective To evaluate the effectiveness of a respiratory muscle online rehabilitation program on stable COPD patients'pulmonary function, exercise capacity, and quality of life (QOL) .Methods Altogether 60 patients with stable COPD were instructed to be trained with an online rehabilitation program for 4 stages. Forced vital capacity (FVC) , forced expiratory volume in one second (FEV1) /FVC, and peak expiratory flow ( PEF) , heart rate and respiratory rate before and after climbing 10 and 20 stairs were measured. 6 - minute walk test (6 - MWT) was conducted. Health related quality of life (HRQOL) was assessed with Saint George Respiratory Questionnaire (SGRQ) . Results After the program training, FVC, FEV,/FVC, PEF, and 6 - MWT results significantly improved, and the heart rate and respiratory rate after 10 - and 20-stair climbing were significantly different (P < 0. 05 ) . The total SGRQ score and the scores of respiratory symptoms, exercise capacity , and disease impact significantly different after the program training ( P < 0. 05 ) . Conclusion The online rehabilitation program can lead to improvements in pulmonary function, exercise capacity, and health status among stable COPD patients. Therefore, it is strongly recommended that stable COPD patients be trained with the program.%目的 探讨以呼吸引导动画为主体的慢性阻塞性肺疾病(COPD)稳定期患者呼吸肌网络训练系统对于改善患者肺功能、活动耐受力和生活质量的作用.方法 60例COPD稳定期患者参加了四阶段网络训练,对其1 s用力呼气容积/用力肺活量(FEV1/FVC)、FVC、最大呼气流量(PEF)、6min步行试验(6-MWT)、试验前后登上10级和20级台阶前后心率和呼吸频率、与健康相关的生活质量进行了观察.结果 患者试验前后的肺功能、运动耐力和健康相关的生活质量评分间差异有统计学意义(P＜0.05),试验前FVC、FEV1/FVC、PEF等肺功能参数分别为[(48.00±1.41)L、(52.89±0.75)％和(41.28±0.04)L/min],而试验后分别为[(56.50±0.71)L、(63.79±1.11)％和(48.36±0.73) L/min],差异有统计学意义(P＜0.05).试验前6-MWT、登上10级台阶和20级台阶呼吸频率、登上10级台阶心率和20级台阶心率等运动耐力的测量结果分别为[(298.00±59.43)m、(40.23±12.23)次/min、(46.22±13.25)次/min、(89.90±0.39)次/min和(100.33±1.52)次/min],而试验后分别为[(360.02±66.50)m、(30.74±10.36)次/min、(34.27 ±14.05)次/min、(85.74±1.09)次/min和(90.67±2.08)次/min],差异均有统计学意义(P＜0.05).试验前圣乔治呼吸问卷(SGRQ)总分、呼吸症状、活动能力和疾病影响得分依次为(52.74±0.01)、(62.23±3.15)、(51.00±1.41)、(45.00±2.83)分,试验后则为(35.68±0.45)、(42.00±1.41)、(36.00±0.00)、(28.00±1.41)分,差异均有统计学意义(P＜0.05).结论 COPD稳定期患者呼吸肌网络训练系统可为患者呼吸肌的康复提供有效途径.
