Traditionally the Threshold IMT<span class="elsevierStyleSup">®</span> is the device used for respiratory muscle training as it provides linear pressure load with the possibility of gradual increments.<a class="elsevierStyleCrossRef" href="#bib0345"><span class="elsevierStyleSup">26</span></a></p><p id="par0080" class="elsevierStylePara elsevierViewall">Due to the visual feedback the IS with a volume-oriented device encourages the following; the performance of the subject, the realization of sustained maximal inspiration and hyperpneia aiming to gain pulmonary volume.<a class="elsevierStyleCrossRef" href="#bib0350"><span class="elsevierStyleSup">27</span></a> It is known that maximum inspiration causes the increase of the transpulmonary pressure and the increase of the pulmonary volume.

A study of asthmatic children also found that a IMT program using the Threshold<span class="elsevierStyleSup">®</span> IMT significantly increased PI<span class="elsevierStyleInf">max</span>, which did not happen with the group that only followed a therapeutic exercise program and conventional education for children with asthma.<a class="elsevierStyleCrossRef" href="#bib0430"><span class="elsevierStyleSup">43</span></a> This demonstrates that breathing exercises alone are not sufficient to produce significant gain in muscle strength and when applied in isolation do not impose a resistive load on the inspiratory muscles.</p><p id="par0120" class="elsevierStylePara elsevierViewall">There are some limitations to our investigation that need to be considered. We used a volitional test of generation of pressure (PI<span class="elsevierStyleInf">max</span>) instead of an electrically evoked potential test for the assessment of muscle strength, only healthy subjects were tested and it is not possible to correlate this experimental situation directly with clinical situations involving patients. Only healthy female subjects were available; there was no male representation. Care should also be taken in comparing the effectiveness of these devices, since the training protocols and intensities of training may differ. It is recognized that the physiological effects of the training are related to its intensity. The differences between the training groups are probably related to the intensity and protocols, and the difference seen at 30 days, with better outcomes in the threshold group could also reflect the growing intensity of the training in this group.</p><p id="par0125" class="elsevierStylePara elsevierViewall">In conclusion, our results showed that the Voldyne<span class="elsevierStyleSup">®</span> device, as well as promoting its known benefits in increasing lung volume, at the same time promotes a similar increased muscle strength to Threshold IMT<span class="elsevierStyleSup">®</span> device, which is designed specifically for the purpose of TMI.
