摘要
目的观察高强度吸气肌抗阻训练对支气管扩张患者运动能力及生活质量的影响。方法采用随机数字表法将60例支气管扩张患者分为观察组及对照组,每组30例。观察组采用PowerBreak型吸气肌训练器进行吸气肌抗阻训练,训练时将吸气阻力值设定为70%最大吸气压(MIP)水平,重复呼吸30次为1组,每天训练2组,每周训练3 d,连续训练8周;对照组同期也进行吸气肌抗阻训练,但吸气阻力值设定为10%MIP水平,其它训练参数及疗程同观察组。于干预前、后分别对2组患者病情严重程度、肺功能、呼吸肌力量和耐力、运动能力及生活质量情况等进行评定。结果与干预前比较,干预后观察组MIP[(144.7±15.8)cmH2O]、6 min步行测试(6MWT)距离[(685.0±98.3)m]明显增加,6MWT测试时的心率[(121.6±6.9)次/min]及主观疲劳感觉评分[(11.6±2.0)分]明显下降,莱斯特咳嗽问卷(生活质量问卷)中的社会维度评分[(5.75±1.08)分]明显升高;对照组干预后上述各项指标结果均无显著变化(P>0.05)。结论高强度吸气肌抗阻训练可显著改善支气管扩张患者运动能力及生活质量,该疗法值得临床进一步研究、推广。
Objective To explore any effect of high-intensity inspiratory muscle resistance training on exercise capacity and life quality for persons with bronchiectasis.Methods Sixty patients with bronchiectasis were randomly divided into an observation group and a control group,each of 30.The observation group received two 30-minute sessions of inspiratory muscle resistance training daily using the PowerBreak inspiratory muscle trainer 3 days/week for 8 weeks.The intensity was 70%of the maximum inspiratory pressure(MIP).The control group underwent the same training with the intensity at 10%of the MIP.The severity of illness,pulmonary function,respiratory muscle strength and endurance,exercise capacity and life quality of the two groups were evaluated before and after the intervention.Results Compared with before the intervention,the average MIP in the observation group and the average distance they walked in the 6min walk test(6MWT)improved significantly.Their average social factor score on the Leicester cough questionnaire had increased significantly,while their average heart rate and self-perceived exertion during the 6MWT had decreased significantly.There were no significant differences in any of these indicators for the control group.Conclusions High-intensity inspiratory muscle resistance training can significantly improve the exercise capacity and life quality of patients with bronchiectasis.The treatment is worthy of further research and application in the clinic.
