Abstract
An improved electrostimulator apparatus, comprises first and second electrodes spaced-apart a predetermined distance, an electrical signal generator for providing pulses of predetermined width and repetition rate to the spaced-apart electrodes, and an LED providing a beam of light projecting between the spaced-apart electrodes toward the object intended to be electrostimulated. The electrodes have substantially co-planar external faces approximately perpendicular to the light beam. The electrodes, signal generator and LED are mounted in an elongated housing having a longitudinal central axis. The electrodes are exposed on an end and the light beam is emitted from the same end and substantially parallel to the central axis. An ON/OFF switch actuates the signal generator and the LED when turned ON. It automatically turns OFF state when released so that the signal generator and the LED are always ON or OFF together.
