1. A muscle-activity diagnosis apparatus comprising:

  • an acquiring section configured to electrically detect an original myoelectric signal from a test subject;

    a transformed-signal generating section configured to generate a transformed signal by performing Hilbert transformation and inverse Fourier transformation on the original myoelectric signal;

    a phase-velocity calculating section configured to calculate a phase velocity of the myoelectric signal on the basis of phases of the original myoelectric signal and of the transformed signal; and

    a state-identifying section configured to identify an activity state of a muscle of a predetermined part of a body of the test subject for each of the unit time on the basis of a plurality of feature quantities of a waveform of the myoelectric signal in a unit time and the plurality of feature quantities including at least a size of amplitude of the myoelectric signal and the calculated phase velocity.
