The electrical treatment of the injured nerves and muscles should be undertaken energetically; both the galvanic or faradic currents may be used. Probably the best form is the galvanic. A small medicinal battery may be utilized, the method of application being as follows: One pole of the battery should be placed over the affected muscle, and the other pole placed in a basin of water into which the patient’s hand is dipped. The current should then be passed. It is better not to use a current of too great intensity, particularly at the start, although it is found in practice that a much greater current can be borne in the early stages of the treatment than when the muscles and nerves commence to recover. As a rule the patient experiences no inconvenience whatever from a considerable current during the first week of his affection, but at the end of a fortnight or three weeks less than one-third of the initial current can be borne. The current should not be passed continuously, but should be used for a short time and then shut off, being again switched on for five or six minutes, and then again shut off. The applications may also be modified by placing one hand in the vessel of water and stroking the affected muscle and nerve with the free electrode. The application of the current should be for not more than half an hour at a time, and may be applied twice in the twenty-four hours. It is quite easy to instruct the patient to perform the electrical treatment for himself in this manner when the paresis is affecting either the upper or lower extremity. With the faradic current the circuit should be closed while the current is at a minimum, and then the quantity of current raised to some 15 to 20 milliampères. For affections of the lower extremity the application may be made by means of one of the usual baths in which the foot is immersed, the other electrode being placed on the back or other suitable position. If both the lower extremities are involved, then both feet should be placed in a bath into each of which the source of electricity is connected. Ionization by means of the faradic current may also be made use of. For this purpose one of the halogens, preferably iodine or chlorine, should be used, it being remembered that chlorine and iodine ions enter from the negative pole, so that in such a case the bath in which the affected limb is placed must be connected with the negative pole of the battery. Subsequently, with either form of electrical treatment, the part should be well rubbed, and passive movements as well as massage are an advantage in promoting the return of normal function. As the muscles gradually return towards their normal state, graduated muscular exercises should be used.
