So, as a means of diagnosis zone therapy has an immense value. Its curative effects, however, are most valuable and significant. Many of the gravest nerve conditions--conditions which failed to respond to the most skilled medical treatment obtainable anywhere--have been completely and permanently cured by the application of the proper pressures--properly made. I recall a very grave case of neurosis--a writer’s cramp--accompanying a neurasthenic condition. This lady--unusually alert and intelligent--was a physical and nervous wreck. Sleepless, harassed by “nerves” in their most aggravated form, she was unable to hold a pen, or to write more than a few minutes at a time, until, on account of the pain and twitching of the arm, wrist, and fingers, she was forced to desist. She could no more have picked up and threaded a needle--let alone have sewed with it--than she could have operated an aeroplane. She was also nearly deaf from a middle ear trouble. Several months’ treatment, using the aluminum comb across the front and back of the hands and on the finger tips, and daily employment of the tongue depressor for four or five minutes, brought about a complete change in the patient’s condition. It relaxed the terrible nervous tension--which was particularly marked along the course of the spine--enabling her to sleep at night, and awake thoroly rested and refreshed in the morning. The writer’s cramp was also completely cleared up. A number of other conditions were also corrected, and the hearing was improved quite 50%. This lady has since resumed her occupation as a private secretary--a position she was forced by ill health to relinquish more than two years ago--and now writes for hours at a stretch, without any return of the cramp in the hand and arm. And, most convincing of all, she can now not only pick up, thread, and hold a needle--something she had not been able to do for years--but she can sew steadily for two or three hours, and feel no disagreeable effects from this feminine debauch. A peculiarly satisfactory characteristic in all these cases is that the improvement is even more apparent the “morning after” than it is immediately after the treatment. Another case of neuritis in the arm and shoulder (brachial neuritis) for more than six years had been unable to raise his arm higher than the shoulder. For the two months previous to treatment he had been obliged to carry it in a sling. The slightest movement of the arm brought about a paroxysm of agonizing pain. A number of hollowed-out spring clothespins were clamped on the fingers of the affected arm (see Fig. 13), and left there for twelve minutes. At the expiration of this time the clamps were removed. The patient gingerly took his arm from its support, and after a minute or two spent in experimenting with it, moved it freely up behind his head and swung it behind his back in a sweeping motion.
