The chiropractic profession pioneered skin temperature differential analysis with the introduction of the neurocalometer more than 70 years ago. This three-dimensional model may be used with any technique, which has as its objective the detection, management, or correction of vertebral subluxation. Correction of vertebral subluxation facilitates the restoration of proper tone throughout the nervous system. Health is dependent upon maintaining appropriate tone in the nervous system. 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. 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. Changes in ranges of motion may be measured to assess dyskinesia.
