| Research Abstract |
In this study, we focused on the Mechanomyogram (MMG) of the diaphragm in order to develop a new respiratory function tests. This method is different from the respiratory function test using a conventional spirogram, and only needs to measure the diaphragm mechanomyogram by electrical stimulation from the skin surface. In comparative experiments for the elderly and young people, MMG amplitude of the elderly decreased significantly, and correlation was observed from mouth pressure ventilation (PImax and PEmax) and respiratory function (VC, IRV and ERV). Therefore, MMGs are able to directly measure diaphragm contractions, and when combined with PEmax and PImax, could offer a more detailed evaluation of respiratory muscle function.
