mulation in a normal manner willalways respond to galvanism. In making the diagnosis of injuredmuscles and nerves, the galvanic current is applied according toPfliigers law, as described in Chapter IX. Each muscle is care-fully examined, and the amount of current necessary to produce acontraction on opening or closing, ascending or descending, is care-fully noted and recorded, together with the manner in which themuscle contracts. A muscle may be made to contract under electricstimulation and yet be far from normal, and it is, therefore, neces-sary to carefully note the particular manner in which the contrac- 176 PRACTICAL ELECTRO-THERAPEUTICS AND X-RAY THERAPY tion takes place in order to determine the different degrees of reac-tion of degeneration. As compared with the reaction of normalmuscles, if the contractions are weak and sluggish, slow or worm-like, reaction of degeneration is in progress. The course of the de-generation is easily determined through frequent electric examina-

As the condition improves, the contractions become moreand more normal until the muscles and nerves assume their naturalfunctions. When the paralysis extends to all of the muscles of a member, in-stead of the sponge electrode so commonly used, the author has thepatient place the hand or foot in a pan of water to which the activeelectrode is connected, the other electrode being on the lumbar re-gion or some indifferent part of the body. This method of admin- DISEASES OP THE NERVOUS SYSTEM 177 istration will also give excellent satisfaction with the faradic andsinusoidal currents. Static and High-Frequency Discharges.—Besides the currentsabove described, the high-frequency discharges from the static ma-chine and the various forms of condensers may be successfully usedin the treatment of degenerated nerves. The direct or indirect static spark from the large ball electrode,though sometimes painful, may often be use
