PROBLEM TO BE SOLVED: To obtain stimulation suitable for preventing lumbago and improving a balancing function by providing forcible swinging for the tensing/slackening of a muscle group mainly in a waist part to a seat, measuring three-dimensional position information in the vicinity of the waist and the tensing/slackening state of the muscle group mainly in the waist and corresponding these to each other. SOLUTION: A controller 3 is constructed by using a computer device, and controls a parallel mechanism 2 based on control information written beforehand from a data input section in a data storage section. For the data input section, a three-dimensional sensor attached to the vicinity of a human coccyx part, a motion capture composed of a plurality of TV cameras for detecting a position by picking up the image of the sphere of reflection attached to the vicinity of the human waist or the like is used. For performing this measuring, measuring time is adjusted beforehand for a surface muscle potential and three- dimensional position information. In other words, based on correspondence by time, the tensing/slackening of a muscle caused by any changes in a waist position is known. |
