Experimental Group (n = 14): Elderly men who received transcutaneous electrical diaphragmatic stimulation to the motor threshold intensity.
Parameters of stimulation:
depolarized current
frequency of 30 Hz
respiratory rate of 14 rpm
rise time (ramp) of 0.7 s
pulse width of 1.2 ms
stimulation motor threshold
electrodes silicon carbon placed two in the parasternal region, next to the xiphoid process in the sense of muscle fibers, and the other two electrodes were fixed on the motor points of the diaphragm

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Increased diaphragmatic muscle strength, assessed by the manometer. The manometer is an analog device with operating range of 0 to ± 300 cmH2O, to check the measurements of maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). Expected to find measures considered technically satisfactory maximal inspiration, lasting at least 2 seconds without air leak and values close to each other (> 10%), computing the largest absolute value obtained. | — |
Secondary
| Measure | Time frame |
|---|---|
| Improvement in lung volume and capacity, as assessed by respirometry, where volunteers remain seated, holding the silicone mask involving the nasal and oral cavities, preventing the escape of air. Expected to find increased tidal volume, minute volume and vital capacity. | — |
