Means, standard deviations and statistical results for the pulmonary flow measurements: forced vital capacity (FVC), forced exhaling volume in the first second (FEV1), FEV1/FVC and the peak of exhaling flow (PEF) for both the experimental and predicted values, for the group treated with conventional chest physiotherapy (CCP) and the group treated with CCP + transcutaneous electric diaphragmatic stimulation (TEDS), in three evaluations.
