RESUMO

Pulmonary rehabilitation programs are considered efficient to individuals with Chronic Obstructive Pulmonary Disease (COPD), nevertheless short term effects are not well established. The main objective of this thesis was the evaluation of the effectiveness of an outpatient short term pulmonary rehabilitation program (STPRP) on individuals with moderate and severe COPD. The sample consisted of 15 volunteers, male (n=10) and female (n=5), with stabilized moderate or severe COPD. STPRP consisted of a short-term experimental protocol (STEP). Every volunteer carried out activities during 15 sessions, 5 times a week during 3 weeks. The following items were evaluated, before and after-STEP application: pulmonary function; sensation of dyspnea; functional capacity and health-related quality of life. The evaluation was done through spirometry and respiratory pressure meter; visual analog scale; walking distance along the six minute walking test (6MWD) and SGRQ (St. Georges Respiratory Questionnaire), respectively. In order to analyze the characteristics of the sample, descriptive statistics followed by comparative analysis were employed. In order to verify intervention effects on the evaluated variables Students t-test was applied to the collected data. The results are expressed in mean values and standard deviation of the difference before and after-STEP and their respective significance levels. The pulmonary function, evaluated by six respiratory parameters, did not show significant statistic alterations. When pulmonary function was evaluated by respiratory pressure meter, significant increase in the maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) was observed. For MIP the difference between before and after-STEP was (12,40 (16,86) cmH2O; p=0,0129) and for MEP (12,40 (16,86) cmH2O; p=0,0129). The sensation of dyspnea, evaluated by visual analog scale, decreased significantly at rest (-2,13 (2,32) mm; p=0,0031) and after effort [-21,40 (30,76) mm; p=0,0174]. The functional capacity, evaluated by the walked distance, increased significantly [42,73 (32,28) m; p<0,0001]. The quality of life, evaluated by the SGRQ, increased significantly all the dominoes [p<0,0001]. In spite of short-term, it was concluded that STPRP produced immediate positive effects, improving pulmonary function (MIP and MEP); decreasing the magnitude of dyspnea sensation at rest and after effort (after-6MWD); increasing the functional capacity and improving the health-related quality of life of the volunteers.
