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.

在本研究中，我们着重于横膈膜的机械肌图（MMG），以建立一种新的呼吸功能测试方法。该方法与传统的螺旋图呼吸功能测试不同，只需要通过皮肤表面的电刺激测量膈肌肌力图。在老年人和年轻人的对比实验中，老年人的MMG幅度明显下降，且口压通气（PImax和PEmax）与呼吸功能（VC、IRV和ERV）存在相关性。因此，mmg能够直接测量膈肌收缩，当与PEmax和PImax联合使用时，可以更详细地评估呼吸肌功能。
