e is of service in electro-diagnosis. The patient should be seated and a vessel oftepid water, into which the electrodes should be constantlydipped, with a sponge for moistening the places of applica-tion, should be at hand. Begin with the faradic current, and compare the reac-tions of the healthy with those of the diseased side.Secure the large electrode (anode) to the sternum by a tapepassing round the body (or the adhesive electrode may beused), and holding the small electrode, fitted with a makeand break key, in the right hand, move it about over thevarious motor points of the healthy side ; this leaves theleft hand free to carry out the electrical manipulations.Separate the coils to their greatest distance, arrange thehammer for slow interruptions, and turn on the current ;gradually bring the coils together, and make a note of thepoint in millimetres distance at which the muscles firstcontract; then let the hammer vibrate rapidly, and 204 A Manual of Practical Medical Electricity
