摘要

PROBLEM TO BE SOLVED: To provide a movement support system capable of reliably supporting only a voluntary movement based on an intention of a tremor patient not only in a case where the tremor patient intends a positive movement, but also in a case where the tremor patient intends a negative movement.SOLUTION: A control device 20 includes a first determination step for determining whether or not a tremor is occurring in a user, using a correlation coefficient calculated from an autocorrelation function on the basis of a myoelectric signal acquired from a sensor 15a, and a second determination step for, when it is determined that a tremor is occurring, determining whether or not the user is making a specific movement, or whether or not the user is keeping a specific posture, using a generation cycle of a grouped discharge calculated from the autocorrelation function. When it is determined that the user is making a specific movement in the second determination step, an impact of an involuntary movement is eliminated and an actuator 12 is driven. When it is determined that the user is keeping a specific posture in the second determination step, the actuator 12 is stopped and a movement of a body region is regulated.
