The fact that Faradization proves so remarkably useful, in these cases of spinal irritation with diffuse cutaneous or mucous tenderness, is in itself a strong diagnostic between this sort of affection and the true neuralgiæ, which, as I have stated are seldom benefited, and are often made worse, by the interrupted current, though the constant current frequently mitigates or cures them. Sometimes where it is not possible to apply the remedy directly to the sensitive surface, we may nevertheless do great good by sending the interrupted current through it. Thus, in gastric sensitiveness connected with spinal tenderness in the upper dorsal region, I have seen very great relief afforded by sending a current from the positive pole, placed on the tender vertebræ, to a broad, negative conductor placed on the epigastrium. And similarly, I have seen an acutely sensitive condition of the neck of the bladder greatly soothed by the passage of a current from a painful lumbar vertebra to the perinæum immediately behind the scrotum. Undoubtedly, however, the more serious cases of spinal irritation will yield only (if they yield at all) to a prolonged treatment in which very skilful use is made of general hygienic measures, and especially of morbal influences. As the brothers Griffin long ago pointed out, although rest is useful in the early stages of this malady, if the disease does not quickly yield to this and to appropriate tonic medication, and perhaps local applications to the spine, it will not do to keep the patient recumbent and confined to the house; on the contrary at whatever cost of immediate discomfort, he (or she for these patients are by far the most frequently females) must be roused up, and persuaded or compelled to take out-door exercise, and if possible to travel, and divert the mind by complete change of scene. When such expensive remedies are out of the question, it seems better that patients, even seemingly very feeble, should take to their ordinary avocations in life again, and fight down the tendency to invalidism. But of course, the decision on such a point must rest with the tact and judgment of the practitioner in each individual case, for there are, doubtless, instances in which the attempt to carry out such a plan, even moderately, would break down the remaining strength, and make matters worse than they were before.
