This absence of pain, which cannot be claimed for correspondingly intense local applications, is to be attributed to the diffusion of the current throughout the body and its surface, as well as through the water of the bath. The redness of the entire back after a galvanic bath, is among the proofs of this diffusion.
Freedom from pain is a characteristic likewise of the faradic bath, properly administered. When too strong a faradic current however is incautiously administered, the resulting muscular contractions are accompanied by an amount of local pain proportioned to the violence of the contractions. By keeping the faradic current within proper limits, all pain can be avoided.
With respect to
MUSCULAR CONTRACTIONS,
the effects of the electric bath may be distinguished from those obtained by other modes of faradization by their comprehensiveness. Many groups of muscles may be made simultaneously to contract by this means. The practical bearing of this on the therapeutics of pareses and paralyses, renders it an important characteristic of the bath.
The physiological effects on
THE MIND
of electric baths, is a natural result of the enhanced tone and vigor of the physical system, and keeps pace with this. Mental buoyancy and even exhilaration are among the most common sequences of electric baths. Although indirect, these results are none the less decided.
It has been my aim in the foregoing remarks to give the reader, as concisely as possible and within the limits which I set for myself in the beginning of the present chapter, a summary of the more important physiological effects of electric baths. As the isolated results of observations made in a limited field by one unaided individual, I trust the shortcomings of this chapter will be viewed indulgently. If what I have said of the physiological effects of electric baths proves the means of stimulating to further investigation more competent observers than myself, my labor, whatever its imperfections, will not have been in vain.
