Purpose from the point of view of the airway resistance and respiratory muscle strength, explore Liu Zi Jue \objective basis, and to provide new ideas for the future design and verification of a reasonably effective rehabilitation program. Fujian Provincial Hospital, Fujian Provincial People's Hospital outpatient or hospitalization in patients with stable COPD 63 patients included in the study, the middle of the loss of three cases (test group 2 patients were lost, the control group lost to 1 case), and eventually collect the number of cases to 60 cases, in accordance with the order of entry into the study, using a random number table, were randomly divided into experimental and control groups. (1) The test group (n = 30 patients): practice \Training frequency are 30min / 1 / d, of 3 months. Before experiment were Liu Zi Jue and systemic breathing exercises, training, training of qualified to participate in the research. During the test, patients filled out daily exercise log, follow-up member of regular follow-up by telephone and / or outpatient follow-up home visits. Test before and after the application of lung function [percentage share of the expected value (FEV% pred), forced expiratory volume in one second (FEV1), one second forced expiratory volume in one second forced expiratory volume / forced vital capacity (FEV1 / effect. Results. Pulmonary function tests, two groups of FEV1 than before the test differences have significant test group (FEV11.12 ± 0.33; 1.30 ± 0.32P lt; O.01); the control group (FEV11.28 ± 0.36; 1.30 Airway resistance test, the test group patients sGaw change there was significant difference [26.00 (20.00-39.75): 36.00 (22.25-64.75) P lt; O.05] Raw Although reduced, but no significant difference (P gt; 0.05); the Raw of the control group, the sGaw There was no significant difference (p gt; 0.05); experimental group compared with the control group sGaw increased, there is a significant difference (test group, dragged down by its wine, spirits, watch and jewelery businesses ± 23.62; control group, 31.47 ± 16.08 P <0.05): two groups of patients Raw was no statistical difference (P gt; 0.05) 3. respiratory muscle strength test, two groups of the MIP, the MEP, although increasing trend but no significant change (P gt; 0.05); After the test MIP, MEP indicators between groups showed no significant difference (P gt; 0.05). Lung function and airway resistance index of pulmonary function (FEV1, FEV% pred, FEV1/FVC) Raw, sGaw have a significant correlation Raw (r = -0.658, -0.579, -0.486 P lt ; 0.01): sGaw (r = 0.707,0.678,0.547 P lt; O.01)]. 5. Pulmonary function and respiratory muscle strength index of pulmonary function (FEV1, FEV,% pred, FEV, / FVC) and MIP correlation (r = 0.581,0.472,0.403 P lt; 0.05); FEV / FVC the MEP correlation (r = 0.464 P lt; 0.05). 6. Lung function and airway resistance, respiratory muscle strength in the multiple regression analysis of the multiple regression analysis were the index of pulmonary function (FEV1, FEV,% pred, FEV1/FVC) as the dependent variable, to airway resistance (Raw, sGaw) and respiratory muscle strength (MIP, MEP) as the independent variable. FEV1 changes by Raw, sGaw, MIP Raw (β = -0.399, P <0.05) sGaw (β = 0.432, P <0.01) MIP (β = 0.322, P |
