<p>It is known that the MMG (mechanomyogram) reflects the mechanical function of the muscle, but its generating mechanism has not been sufficiently clarified. In this study, when the gastrocnemius of the rat was electrically stimulated, the acceleration-MMG and the displacement on the surface of the muscle were measured using an accelerometer and a laser displacement transducer, respectively, and the intramuscular pressure was simultaneously measured using an optical fiber inserted into the muscle. The generating mechanism of the acceleration-MMG was suggested by the comparative reviews of the following data obtained from the muscle where the induced twitching occurred: the latencies, propagation velocities and amplitudes among the acceleration-MMG, displacement and pressure. Dantrolene, which suppresses the emission of Ca^2＋ from the sarcoplasmic reticulum, was also injected intramuscularly and the measurements were similarly carried out. The following conclusions were obtained: (1) the MMG measured by the accelerometer can be dynamically transformed into the displacement of the surface; (2) the MMG consists of the propagation and composition of the shear wave caused by the change of intramuscular pressure with the muscle contraction;(3) the location of neuromuscular junction can be estimated from the latency of the MMG and the intramuscular pressure wave.</p>
