The bariatric surgery has been considered an effective procedure for weight and co-morbidities reductions and consequently for the life quality improvement. However, in the same way as all surgeries, it can bring complications and alterations in the pulmonary function meanly in obeses. In this way, the objective of this study was the evaluation of the pulmonary function, the respiratory muscular strength and the thoracic mobility after the physiotherapy treatment with transcutaneous electric diaphragmatic stimulation (TEDS) in patients submitted to Roux-en-Y gastric bypass (RYGB) and the quality of their lives after the weight reduction. Forty-four morbid obese women with BMI > 40kg/m2 were studied. The Ethics Committee of Researches properly approved this study. The obese women were evaluated through spirometry, manovacuometry and thoracic abdominal cirtometry in the pre-operative period and fifteen and thirty days after the surgery ; they were randomly separated into two groups of twenty-two each. The Control Group (CG) was submitted to the conventional chest physiotherapy (CCP), while Experimental Group (EG) was submitted to the conventional chest physiotherapy associated with the TEDS (CCP+TEDS). The assessment of the life quality occurred between the sixth and the sixteenth month of the post-operative period by the BAROS questionnaire. To the statistics analysis was used GraphPad InStat for Windows, 3.05 version, the test of Kolmorogov Smirnov, Friedman and Mann-Whitney. It was considered significant p<0.05. To the data analysis of the BAROS questionnaire, descriptive statistics tests like average, standard deviation, absolute numeral values and percentage were used. The results showed that there were no statistically significant differences to the flows and pulmonary volume measurements and to the MIP (p>0.05). Related to the MEP, there was a progressive and significant reduction from the pre to the thirty day after the surgery for the CG, but not to the EG. It was observed that the alterations in the thorax abdominal mobility were not significant to the CG in any evaluation. However, with the EG, the differences were significant at the three moments of evaluations and to the three evaluated locals. Finally, the result of the quality of life questionnaire BAROS application showed that the bariatric surgery got satisfactory results to 2,27%, good to 9,10%, very good to 36,36% and excellent to 52,27% of the patients. Based on these results it is possible conclude that both CCP and (CCP) associated with TEDS were effective in the maintenance of pulmonary flows and volumes, of the capacity of muscle endurance, and the maintenance of the strenght muscles at the post-operative period of the RYDG. However, the CCP associated with the TEDS revealed to be much more effective not only to the maintenance of the expiratory muscles strenght as to guarantee a greater thorax abdominal mobility by increasing the muscle contraction. The loss of overweighting contributes to the life quality improvement in morbid obese women.
