PURPOSE: To cure a muscle stiffness by adjusting the On time and Off time of intermittent operation, combining together an intermittent living body stimu lant, therapeutic clothing with appropriate part opened, a manual of operating instructions, and a book of descriptions for effective spot therapy, and thereby giving dynamic contraction and slack by muscles in a longer intermittent time than conventional and with a stronger stumulance.

CONSTITUTION: The lower half of a small rotatable cylinder 17 accommodates a PTC heat emitting body 16 while the upper half houses a heat insulating substance 6, and therein a rod magnet 18 is inserted vertically, over it outside thereof and an electric magnet 19 changing the current direction with turning on and off of an electronic switch and a lithium ion battery 24 are arranged. These are accommodated in a box with its central bottom part opened, and an adhesive band tape (Magic Tape(R) 10) is affixed to each end thereof. On time and Off time of the intermittent operation repeated alternately at short intervals shall be adjustable individually, and for example, Off time can be set to 1/4 thru 3 times as large as the On time, which permits a muscle contracted with stimulance to slacken slowly within the period with no stimulance.
