The invention is a percussor comprising an anvil, a hammer, a coil, and a pulse generator. The anvil is equipped with a force-receiving surface and a force-delivering surface which are rigidly connected together, the force-de livering surface being intended for contact with a patient's body. The hamme r is also equipped with a force-receiving surface and a force-delivering sur face, the hammer being attached to the anvil in such a way that the hammer's force-delivering surface and the anvil's force-receiving surface are mechan ically free to come together or move apart. The coil forces the hammer's for ce-delivering surface and the the anvil's force-receiving surface to separat e when the coil is energized with an electrical current. The pulse generator supplies repeated electrical current pulses to the coil which causes repeat ed impulse forces to be applied to a patient's body whenever the technician applies a continuing force to the hammer's force-receiving surface.
