Contact dermatitis after transcutaneous electric analgesia

Abstract
Transcutaneous electric analgesia, based on the gate control theory, is used in stump pain, lumbar pain, traumatic pain following nerve damage and sciatic neuralgia. 3 patients using this method, showed contact dermatitis at the sites of contact of the electrodes. Patch tests were positive with the electrolyte gel, and in 2 cases, with propylene glycol. Transcutaneous electric analgesia may cause a certain number of side effects similar to those encountered with electrocardiography.
