Chiropractic is "A system of
adjusting subluxated vertebrae of the spinal column by hand only for the
elimination of the cause of dis-ease and for the restoration of health". B. J.
Palmer
"A subluxation is the condition of a vertebra that has lost its proper
juxtaposition with the one above, or the one below, or both; to an extent less
than a luxation; which impinges nerves and interferes with the transmission of
mental impulses.
