Abstract: Vibrator systems, methods of making and operating such systems, and apparatus for controlling such systems. An illustrative vibration system includes first and second sets of vibrators adapted for providing therapeutic vibrations to a mammalian body, and a controller providing a first set of instructions to the first set of vibrators, and providing a second set of instructions to a second set of vibrators, wherein the first and second set of instructions are different. Another illustrative vibration system includes a therapeutic vibrator adapted for providing therapeutic vibrations to a mammalian body a controller adjustable for controlling a vibrator to a user selected amplitude of magnitude A, and which generates output instructions to the vibrator to initially operate the vibrator at an amplitude that is a fraction of A prior to generating output instructions to the vibrator to operate the vibrator at the desired amplitude A.
