Tone and tensegrity are elegant theoretical models with practical clinical implications. Any deviation from normal tone, that of being too tense or too slack, causes a condition of renitence, too much elastic force, too great resistance, a condition expressed in function as disease. In order that the body will not be crushed by this weight it is necessary to have an internal resistance to equal this weight. Nearly four decades later, neurosurgeon Breig described how adverse mechanical tension on the spinal cord may result in abnormal neurological function and the development of pathology. Intelligent life, the soul, depends upon the execution of functions.
Functions performed by normal energy is health.
Disease is the result of the performance of functions above or below a normal degree of activity. Impulses properly transmitted through nerves, result in functions being normally performed, a condition which results in health. The ability to maintain tone requires a nervous system free of interference. Restoration of tone is dependent upon correction of vertebral subluxations. Altered autonomic tone may be evaluated using skin temperature measurements.
