| Research Abstract |
The common peroneal nerve was electrically stimulated and muscle contraction of the tibialis anterior muscle was induced. The mechanomyogram was measured with a laser displacement meter and an acceleration sensor attached on the skin. The system, of which input was electrical stimulation and the output was mechanomyogram, was identified with the fifth-or sixth-order model. The natural frequencies of the system agreed with those originated from the elasticity of the muscle and subcutaneous fat. The relationship between stimulation strength/frequency and viscoelasticity was revealed.
