Effects of Neuromuscular Stimulation on Pulmonary Function,Somatic Symptoms and Physical Activity Ability in Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease
Objective:To explore the effects of neuromuscular stimulation on pulmonary function,somatic symptoms and physical activity ability in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods:92 patients with AE-COPD were divided into control group(respiratory training intervention,n=46)and experimental group(neuromuscular stimulation inter-vention on the basis of control group,n=46)by random number table method.The changes of pulmonary function indexes[forced vital capacity as a percentage of predicted value(FVC％pred),forced expiratory volume in the first second(FEV1)/forced vital capacity(FVC)],somatic symptoms[modified British medical research council dyspnea scale(mMRC),St.George's respiratory questionnaire(SGRQ)]and physical activity ability[6-minute walk test(6MWT),appendicular skeletal mass index(ASMI)]were observed in two groups.Re-sults:8 weeks after intervention,the FVC％pred and FEV1/FVC in two groups increased,with the experimental group being higher than the control group at the same time(P＜0.05).8 weeks after intervention,the scores of SGRQ and mMRC in two groups decreased,with the experimental group being lower than the control group at the same time(P＜0.05).8 weeks after intervention,the 6MWT and ASMI increased in two groups,with the experimental group being higher than the control group at the same time(P＜0.05).Conclusion:Neuro-muscular stimulation can effectively improve pulmonary function and somatic symptoms,and improve physical activity ability in patients with AECOPD.
