44 and 46 are to include appropriate electronics not shown which when connected to an appropriate power source not shown will cause elongated arm 32 to move across the body of the human 22 along a preprogrammed path 48 it is to be understood that the electronics can be modified to have the elongated arm 32 to move along any desired preprogrammed path 48 it is also considered to be within the scope of this invention that the human 22 can select any one of several different preprogrammed paths 48 generally the preprogrammed path 48 will result in movement completely across an area of the body of the human 22 such as is shown the back area of the human 22 electrically connected to the electronics within box 42 is a stepping motor 52 stepping motor 52 is mounted on the bottom 34 stepping motors work well with electronics in establishing and continual repeating of the preprogrammed path of movement the stepping motor 52 is connected to a chain drive 54 the chain drive 54 is mounted about an idler pulley 56 which is fixedly mounted on the bottom 34 one end of the chain drive 54 is pivotally secured to a pin 58 with the opposite end of the chain drive 54 being pivotally secured to a pin 60 pins 58 and 60 are fixedly mounted to a block 62 the block 62 is slidingly mounted on a guide rail 64 the guide rail 64 is fixedly mounted on the bottom 34 it is to be noted that the block 62 is permitted to move only longitudinally on the guide rail 64 the block 62 will come into contact with a stop block 66 which is fixedly secured adjacent one end of the guide rail 64 the.
