It follows that stimulating the whole pinna is as effective as stimulating individual acupuncture points. Therapeutic apparatus according to the invention comprises a pair of earpieces 10 joined by a band 12 to fit on a patient's head. Each earpiece 10 is provided with an inwardly directed light source 14 comprising a plurality of light emitting diodes (LEDs) powered from an electrical mains supply by way of a combined plug and transformer 16 , a cable 18 and a control box 20 . The control box 20 comprises a switch 22 whereby the dc power to the light sources 14 is turned on to irradiate the patient's outer ears with radiation of a selected wavelength and a rotary control 24 for adjusting the length of time it is on.
