Abstract: A resonance frequency stimulator for increasing blood circulation by having a four-legged animal or person standing upon a top plate through which vibrations are transmitted. The top plate is oriented substantially in a horizontal plane and it rests resiliently on a plurality of coiled compression springs at a predetermined height above a bottom plate. Fastening structure passes through the coiled compression springs to secure the top plate to the bottom plate. A rotary vibrator with motor is mounted on the top plate adjacent the front end of the top plate for producing a resonance frequency vibration in the top plate. A frame assembly surrounds the front end, the rear end and the lateral sides of the bottom plate. A handrail assembly extends upwardly a predetermined height from the frame assembly along both lateral sides thereof and also transversely thereto at a position rearwardly of the motor.
