This form of current is commonly applied by means of two moistened electrodes attached to the storage cells of a battery. This current is continuous and its application is therefore usually painless, except at the time of the "make" and "break" - i.e., at the time of the application of the electrodes and of their removal. Movement of the electrodes from one point to another on the skin should be effected by sliding them along the surface of the body and not by abruptly removing them from one spot and applying them to another, thus avoiding the production of a somewhat painful electric shock. The current should be turned on gently at first and increased in strength as the treatment progresses, and at the termination of the treatment it should gradually be lessened in strength and not abruptly shut off. The apparatus is simple and its detail can easily be mastered by a careful study of the switches and of the rheostat - a device for regulating current. The application of this form of electrical treatment will frequently be left to the nurse and it would be advisable for her to experiment upon herself with the electrodes before applying them to her patient, thereby familiarizing hereself with the sensations likely to be produced by the current at various strengths.


The galvanic current is employed in the treatment of paralyzed muscles to improve their nutrition by means of the improved blood supply, which is one of the effects of the current, and to directly stimulate the muscle cells themselves, upon which the current has a marked effect.
