These men also emphasized the fact that the circulation within the blood vessels, being propelled by the heart, needs less attention during disease than the circulation of the fluids in the spaces between the cells and through the lymph vessels and glands. Neuropathy, therefore, also lays great stress on applying manipulation and thermal applications to the lymphatic system. Neurotherapy While the exponents of the above systems of spinal manipulation differ widely in their theories as to the cause of disease and the means of removing such cause, their methods of treatment furnish considerable evidence of satisfactory results. This seems to suggest that there must be some real value in each system and that a great deal of the difference between these apparently opposed methods of treatment lies in the claims of their exponents. It will be shown presently that, in their final analysis, the osteopathic spinal lesion, the chiropractic subluxation and the naprapathic ligatight represent one and the same thing. Natural Therapeutics is broad enough to embrace all methods of treatment, no matter what their source, provided they harmonize with the fundamental laws of cure. Gradually, therefore, after having gathered the constructive elements from all the various methods of manipulation, after considerable spinal dissection and, above all, after close observation of the results obtained in hundreds of obstinate acute and chronic cases, we of the School of Natural Therapeutics have evolved our own system of spinal manipulation and have named it neurotherapy. The Relation of Neurotherapy to Other Manipulative Systems Osteopathy, chiropractic, naprapathy, neurotherapy and spondylotherapy, as we have learned, are various systems of maipulative treatment which have been devised mainly to correct spinal and other bony lesions, shrinkage and contracture of muscles, ligaments and other connective tissues. Important as these methods are in the treatment of acute and chronic diseases, by themselves they are not all-sufficient because they deal only with the mechanical causes of disease, not with the chemical, thermal or with the mental and psychical. The most efficient spinal treatment cannot make good for the bad effects of an unbalanced diet which contains an excessive amount of poison-producing materials and is deficient in the all-important mineral elements or organic salts. Just as surely as mental therapeutics and a natural diet cannot correct bony lesions produced by external violence, just so surely is it impossible to cure dementia praecox, monomania or obsession, or to supply iron, lime, sodium, etc., to the system by correcting spinal lesions.
