CANCELLIERO-GAIAD, Karina Maria; IKE, Daniela  and  COSTA, Dirceu. The effect of transcutaneous electrical diaphragmatic stimulation on respiratory parameters of Chronic Obstructive Pulmonary Disease patients. Fisioter. Pesqui. [online]. 2013, vol.20, n.4, pp.322-329. ISSN 1809-2950.

The objective of this study was to evaluate the effect of transcutaneous electrical diaphragmatic stimulation (TEDS) on respiratory muscle strength and endurance, thoracic-abdominal expansibility and spirometric variables of subjects with chronic as obstructive pulmonary disease (COPD). Eight COPD patients submitted to respiratory physiotherapy received treatment with TEDS twice a week for 06 weeks, totaling 12 sessions. Before and after TEDS they were evaluated by the following parameters: maximal inspiratory pressure (MIP); maximal expiratory pressure (MEP); axillary, xiphoid and abdominal cyrtometry; and spirometry. After the Shapiro-Wilk test, the paired Student's-t test and the Mann-Whitney test were applied for comparison of the two stages (before and after TEDS). For comparison of the before, after (post-1st session), 1st, 2nd, 3rd, 4th week stages, the ANOVA followed by Tukey test were applied (p<0.05). In accordance with the results obtained it was observed that TEDS promoted significant increase in: MIP (47.3%); MEP (21.7%); axillary (55.5%); xiphoid (59.2%) and abdominal (74.2%) cyrtometry, but not in the spirometric variables. In longitudinal analysis (in the 4 following weeks) the increase found in MIP and in thoracic-abdominal expansibility was maintained. Thus, we conclude that TEDS promoted improvement in respiratory muscle strength and thoracic-abdominal expansibility in COPD patients without alterations in spirometric variables, and some parameters were maintained in the following 4 weeks..
