System, method, and program for recognizing myoelectric signal-originating motion

A method for evaluating a movement of a subject, the method comprising:

• detecting a myoelectric signal indicating an activity of a muscle when a subject performs a movement intended to be a predetermined movement comprising a jaw movement, a tongue movement, and a throat movement;
• outputting a processed myoelectric signal by applying predetermined processing on the detected myoelectric signal;
• and
• determining a motion level in the predetermined movement of the subject, based on a pattern contained in the processed myoelectric signal.

A classifier used for evaluating a movement of a subject, the classifier comprising:

• detection means for detecting a myoelectric signal indicating an activity of a muscle when a subject with no impairment in a predetermined movement comprising a jaw movement, a tongue movement, and a throat movement performs the predetermined movement;
• processing means for outputting a processed myoelectric signal by applying predetermined processing on the detected myoelectric signal;
• and
• learning means for learning a pattern contained in the processed myoelectric signal as a pattern in the predetermined movement.
