المستخلص The purpose was to determine the acute effect of transcutaneous electrical diaphragmatic stimulation (TEDS) on ventilatory variables in patients with chronic obstructive pulmonary disease (COPD). 70 male subjects participated in this study; they were assigned to two groups: group (A) study group included 50 patients with age ranging from 45 to 55, and were diagnosed as having chronic obstructive pulmonary disease. They were chosen from banha chest diseases hospital and were receiving medical therapy. group (B) control group included 20 healthy subjects with age ranging from 45 to 55. Both groups had received one TED{u2019}s session. The electrical current was pulsed, biphasic, and symmetric. The intensity of the current was the minimum necessary to obtain diaphragm muscle contraction and gave the subjects a pleasant sensation. The assessment concerned with the ventilatory functions included, forced expiratory volume in first second (FEV1), forced vital capacity (FVC), the ratio between forced expiratory volume in one second to forced vital capacity (FEV1 / FVC) and maximum voluntary ventilation (MVV) were measured before and after the session. This study demonstrated that using TEDS for one session caused a significant improvement in COPD patients and less improvement in healthy subjects as follows: increased FEV1 range of (20.83%) and (10.63%) respectively, increased FVC of (4.46%) and (6.54%) respectively, increased FEV1 / FVC ratio of (12.17%) and (3.65%) respectively and increased MVV of (20.80%) and (10.63%) respectively.
