PROBLEM TO BE SOLVED: To suppress involuntary movements mixed in when a tremor patient makes voluntary movements.SOLUTION: A tremor suppression system 10 includes a brace 11 mounted on a user H and a control device 12 which controls movements of the brace 11. The brace 11 is equipped with an arm 14 movable in a direction of movements of a body region, a motor 15 for moving the arm 14, and a myoelectric potential sensor 17 for acquiring a myoelectric potential at the movements of the body region. The arm 14 moves the body region only in a direction of voluntary movements by the driving of the motor 15 and is fixed in a manner to regulate the movements of the body region when the motor 15 stops. The control device 12 includes a database 28 in which data to determine presence or absence of the voluntary movements is stored, a movement estimating means 29 which estimates the presence or absence of the voluntary movements in measuring the myoelectric potential based on the data, and a command means 30 for commanding the motor 15 to activate in accordance with the estimation. The ordering means 30 drives the motor 15 when the voluntary movements are estimated and stops the motor 15 when they are not estimated. |
