摘要

Synchronism of body motion rhythms is continuously evaluated. The method comprises: a first calculation process for calculating the time at which a phase has changed by a predetermined angle from the phase of a signal at a predetermined time, and calculating the time at which the phase has changed by twice the predetermined angle from the phase of the signal at the predetermined time; and a second calculation process for calculating an evaluation coefficient on the basis of those times.
