PCT No. PCT/GB89/01309 Sec. 371 Date May 21, 1991 Sec. 102(e) Date May 21, 1991 PCT Filed Nov. 2, 1989 PCT Pub. No. WO90/04997 PCT Pub. Date May 17, 1990.An electro-therapeutic device comprises an elongate hand held casing 1 having a tip electrode 4 at one end and an electrode 11 along one side. The tip electrode 4 is placed against the body and a high voltage (40 to 90V) is passed between the electrodes to stimulate the body at low resistance or acupuncture points. In a first aspect of the invention a low voltage DC current passes through the body and changes in the resistance of the body are used to modulate an audible signal to indicate when a low resistance point is reached. In a second aspect the casing 1 is of elongate cross-section so that electrode 11 sits snugly in the web of the hand. In a third aspect of the invention a pulsed, bipolar waveform is applied to the electrodes to avoid electrolytic action in the body. A solid state (transistor/diode) switch is also described for connecting the electrodes across a secondary winding of a transformer during a stimulation mode.
