Drop Table Adjusting using Thompson Technique by Dr. Zemelka
A
Historical
Perspective
Chiropractic,
developed by Dr. D.D. Palmer in 1895, began in
Davenport,
Iowa and has grown throughout the world to become one of the leading
Health Care Systems providing services to millions of people in
practically every country. Based on the premise that the body has an
Innate Ability to Heal Itself, the Doctor of Chiropractic spends over
4,000 hours to learn how to detect abnormalities of the spine called
subluxations, that interfere in the body's inherent desire to
maintain homeostasis. These subluxations interfere with the normal
conduction of nerve impulses from the brain that control every aspect
of the body, from the smallest tissue cell to the muscles, ligaments
and organs that we depend on for maintaining a normal life here on earth.
Adjusting the
spinal segments is not a new concept, which has been documented in
many early pictographs that show methods used by early health
specialists adjusting segments in the spine. Adjusting the spinal
segments has been reported in many cultures around the world from the
walking on the back by South Pacific natives to the Bonesetters of England.
Although Doctors
of Chiropractic focus primarily on the spine there are also special
techniques used to adjust other areas of the body, such as the
shoulder, ribs, elbows, wrists and hands, knees, ankles and feet. The
more prominent Adjusting Techniques taught at Chiropractic Colleges
are Thompson, Gonstead, Diversified, SOT, Toggle Recoil, Logan and Activator.
We will focus
primarily on the Thompson
Technique
since it is my specialty and I was privileged to be an understudy for
many years with Dr. J. Clay Thompson the originator of the technique.
The Thompson
Technique utilizes a "Segmental Drop Table" to enhance the motion
force imparted towards the segment or area to be Adjusted. Dr.
Thompson introduced the concept of adding motion by inventing a
headpiece that would drop away as the adjustive thrust was applied to
the vertebral segment. He was granted a patent in 1955 on his concept
and thusly was born the Palmer-Thompson
drop headpiece. Since the new idea was
such a success Dr. Clay then went on to invent a table with drop
pieces for adjusting the dorsal, lumbar and pelvic area. this came
about in 1957 and from there the rest is history. Today there are
numerous manufacturers of drop-piece tables used around the world.
The "Segmental
Drop System" takes advantage of the spine's inherent design of
the joints in order to move the spinal segment in the direction that
will improve the motion of the segment with the one above and below.
It just makes good sense that since the spinal joints face front to
back and have an incline that slopes more naturally backwards that we
can effect increased motion by applying an adjustment from P to A,
(Posterior to Anterior) and with an inferior to superior line of
correction. The majority of the spinal adjusting utilizing the Thompson
Technique
has the patient lying prone. (face down.) This is the basis for Dr.
Clay's theory of proper spinal adjusting and the driving force that
lead him to invent the drop table.

Leg
Length Analysis Concept
Another important
aspect of the Thompson
Technique is the method used to determine an imbalance in the length of the
legs when observed with the patient in a prone position on the table.
The "Leg Length System" is based on the early work of Dr.
Derifield of Detroit, Michigan. The neurological basis for balance is
found in the Reticular System of the brain where the Inhibitory and
Facilitory systems maintain balance of the musculature of the body. A
neurological imbalance will affect the musculature of the legs
resulting in the appearance of one leg being short when observed with
the patient in the prone position. The feet are observed in the
extended position and then flexed to compare one with the other
noting any difference in the appearance of length. Contraindications
would be an anatomical short leg, history of poorly healed fracture,
or a joint implant.
The "Leg
Length Analysis" has five levels of interpretation developed by
Drs. Derifield and Thompson. The length is observed at the juncture
of where the heel and shoe come together with inversion and eversion
removed and no dorsiflexion or plantar flexion of the feet.
Subluxation levels are based on the "Leg Analysis "to
determine what areas that may need to be adjusted. This is correlated
with Physical Examination, X-ray and Motion findings, Palpation and
Instrumentation utilized by the Doctor of Chiropractic.

Segmental
Drop Adjusting - The Legacy Continues
The development of
the "Drop Table" has come a long way since the early days
of discovery by Dr. J. Clay Thompson. What started out as an improved
method for delivering the "Toggle Recoil" during the era of
B.J. Palmer, has grown into a world wide use of the Segmental Drop
System for Chiropractic Adjusting. The following story comes from
hearing Dr. Thompson lecture to students and field doctors over the
years and represents a chronology of historical importance.
The "Palmer-Thompson" drop headpiece was developed by Dr.
Thompson in an effort to come up with an easier method of delivering
the toggle thrust on something other than the knee chest table or the
side posture bench with a fixed headpiece. His experience as a
student in the Palmer Clinic while treating patients in the public
clinic, which was held in the gymnasium, resulted in several
ineffectual attempts to toggle a number of patients. The patient's
head was placed on a firm headpiece that resulted in reflected force
into the doctor's arms and shoulders. The early training incorporated
a follow through drop of the doctors upper torso following the
delivery of the toggle thrust, which even with that, Dr. Thompson
found it difficult to accept.
While attending
Palmer College of Chiropractic, Dr. Thompson had developed at his
apartment, a side posture table with the head piece mounted on an
auto jack from a Model T car. This was done to accommodate the height
of the head when the patient was placed in the side posture position.
When the thrust was delivered there was some vertical drop or give
that added to the toggle thrust. He surmised that if he could refine
and control this drop it would be of some benefit to the proper
execution of the toggle adjustment.
The first attempt
resulted in a headpiece that was spring-loaded and had a drop of
about ½ inch with the other end that swiveled and a catch that
latched when the two pieces came together. This headpiece was
utilized to experiment with the tension of the spring and various
mechanisms for the latch that locked the headpiece down when the
toggle thrust was delivered. The unit worked so well that several
were made and thus was born the "Toggle Drop Headpiece" or
as many of us came to know the Toggle Board.
When I came to
Palmer College in September of 1972 one of the first things you did
was to buy one of these toggle boards even before purchasing your
books. If you were lucky you would find a senior who was graduating
and get a real good deal. Today there are several manufactures such
as Lloyd Table Company and Thuli Tables that produce excellent toggle
drops, that can be adjusted for the weight of the patient's head.
As the story goes,
Dr. Thompson demonstrated the drop headpiece for Dr. B.J. Palmer. Dr.
Clay said many times, that B.J. felt it enhanced the toggle
adjustment and they entered into an agreement to put the drop
headpiece on the tables to be used in the clinic and classrooms. Many
of these tables are still in use in the toggle classroom at Palmer
College. They were refurbished with new upholstery a few years ago,
and continue to serve in the training of the students in learning
toggle recoil adjusting.
The legacy continues...
