D. D. Palmer of Davenport, Iowa (USA) started chiropractic in 1895.
He had been a healer, and one day he found a big vertebra bump on one
ear of a deaf patient. It had been there for 17 years. He thought
that this was the reason for the deafness and spent a long time to
explain the need for treatment of the bump. After the patient agreed,
he pushed back the bump in order to put it back to the place where
it was supposed to be. Then, the ear function of the patient came
back to normal.
He focused on finding the spinal misalignment and correcting
it, and he succeeded in many cases. On September18,1895 he named this treatment method CHIROPRACTIC which means Jdone
by hand." Now this date is known as Chiropractic
He started the first chiropractic school in Davenport, Iowa two years
later in 1897.
Dr. B. J. Palmer, the son of D. D. Palmer, changed the school name to the
<PALMER SCHOOL OF CHIROPRACTIC> in 1905. In 1910, he introduced
X-Ray machines in order to make chiropractic a more scientific procedure.
He had been trying to find <the specific vertebra> which was
the source of the problem for the whole spine.
He had been trying to find out the Jwhen", Jwhere", Jhow"
and Jwhy" of the adjustment. However, after the X-ray was introduced,
he started concentrating on the Atlas adjustment, and it was called
JH. I. O." (Hole in one) technique. Over 2000 students
were studying at Palmer College in 1919.
Atlas rotation was explained in 1924, and H. I. O. became a main procedure
of all the chiropractic procedure through the introduction of the vertex
view X-ray in 1933.
Based on the X-ray reading, Dr. John F. Grostic discovered a new way
of reading X-rays so that a lighter tapping pressure could be used
and better results were achieved. Dr. Roy W. Sweat of Atlanta, Georgia
JAtlas Orthogonal Technique" in 1980.
