Atony of the _muscularis_ of the intestine is admittedly the direct cause, in most instances, of constipation. It is the condition known as “torpor of the bowels.” It is ordinarily due to abnormal innervation of the parts. The inefficient innervation may be—and in females frequently is—reflex, or its cause may be sought for in the central nervous system. The condition of the voluntary abdominal muscles is likewise a factor in the alvine process. Sluggishness of the abdominal (portal) circulation is a not infrequent etiological concomitant of constipation, and, finally, the conditions grouped as “dyspepsia” may form the causative feature of a case. I have mentioned these different causes simply in order to account to some extent for the almost wonderful effects in this condition of electric baths. When we consider that in every one of the morbid conditions here enumerated, electricity is a very efficient remedy, and that for the resulting muscular atony it may be called a specific, it will not appear surprising that a mode of application which brings the electric influence to bear on both cause and effect—often on a combination of several of the causes enumerated, should be attended with such brilliant results. I have thus far met with no failure in the electro-balneological treatment of constipation. In the majority of cases the following method has proven the most efficient. The first ten minutes of the bath should be devoted to the administration of a galvanic current, as intense as can comfortably be borne by the patient. The one pole should be connected with the head-electrode, the other, by means of the surface board, applied alternately, to the epigastrium, chiefly, and to the hypogastric region. The current should a portion of the time be ascending, the rest descending. Occasionally the current should be rapidly reversed by means of the commutator, the intensity however having been previously reduced, in order to avoid too severe a shock; this will cause efficient contractions of the abdominal _parietes_, and probably also of the intestinal _muscularis_. The second ten minutes of the bath should be devoted to faradization, employed in the same manner as the previous galvanization, only that here the direction of the current is immaterial, and no reversals are requisite. The current should be of sufficient intensity to produce energetic but not painful contractions of the abdominal parietes.
