the galvanic bath has few if any superiors. The degree of counter-irritation can be very nicely determined by regulating the intensity of the current. The characteristic tingling sensation of the galvanic current is felt over the entire surface, corresponding in degree of course to the intensity of the current; while the redness of the skin, bearing a like relation to the intensity of the current, is observable more especially near the electrodes, being particularly conspicuous over the entire back. Concentrated local counter-irritation can be obtained by the use of the surface board.
The counter-irritant effects of the galvanic bath, differ from those of ordinary counter-irritants in their freedom from pain, even the slight burning sensation accompanying strong currents ceasing with the application. The redness remains quite a while and the stimulus to the peripheral circulation causes the persistence for some time of a “glowing” sensation all over the body.
In the chapter on physiological effects enough has been stated to make it apparent that as a
GENERAL INVIGORANT AND TONIC
the electric bath can have few if any superiors. In the healthy organism, however, the stimulant and tonic effects of the baths are much less marked than they are where the general condition is “below par.” In health there is little or no margin for improvement. The results obtained are temporary stimulation, and a permanent invigoration which partakes more of artificial development than anything else. It is analogous to the development by gymnastic or other exercise of a previously healthy set of muscles. Where we meet with atonic conditions however, with debility, malnutrition, want of energy or general asthenia of an obscure nature, and amenable to electric influence, the tonic effects of the baths become striking and brilliant. I have observed cases where patients fairly bloomed up under their influence and acquired actually more physical strength and weighed more than before they became sick. When we consider how in such conditions as those mentioned, patients are made to swallow pills and mixtures for months or years, or, more appropriately, and if they can afford it, are sent abroad, we can realize the importance of an agent by means of which the desired end can be obtained more conveniently, certainly, economically and in a shorter time than by any other means. There is no rule without its exceptions, and I freely admit that in many instances where persons are, as the saying is, “run down,” a sojourn in some mountainous region or a course of sea-bathing, etc., would do them more good than anything else, electric baths included. The results obtained from these last are however sufficiently uniform to justify us in looking for very favorable results in every case.
In the preceding chapter I have already dwelt on the
HYPNOTIC AND SEDATIVE INFLUENCE
of the baths. It is only necessary to state here that this influence manifests itself still more decidedly in corresponding morbid conditions than in health. The greater the degree of restlessness, irritability or wakefulness, the more strikingly does the soothing and hypnotic influence of the baths—appropriately administered, of course—become apparent.
IMPROVEMENT OF NUTRITION,
as manifested by rapid increase of weight, and which I have likewise touched upon in the preceding chapter, is a reliable, constant effect of electric baths. Where previous loss of weight is due to an incurable organic disease, it is, if at all obtained, of course much less in degree, as well as transient. When due, however, as is frequently the case, to causes that are amenable to electrical influence, the increase in weight is marked, and has a tendency to be permanent.
