The purpose of this brochure is to inform the new patient of the step by step process that is taken in our office to determine whether we can help you. If we can determine on the first visit that we can help you, and you do not understand any part of the procedure, please ask the doctor to explain it. During the first visit the doctor will want to know if you have one leg that is shorter than the other, and if you have a pelvic distortion If a leg shortness and pelvic distortion exists, the doctor will recommend that x-rays be taken of our neck and head to determine if the atlas vertebra has been displaced. The x-ray is the only means by which the doctor can accurately know in just what directions the atlas has been displaced. He must measure these directions in order to figure a means to correct the atlas to normal position.


The atlas vertebra is the top most bone in the spinal column, and is located where all the nerves ascend and descend to and from the brain (see Fig. 1). When the atlas is displaced (normal to abnormal position), the nerves at the atlas level are stretched which cause a short (contractured) leg, a distorted pelvis, and spinal imbalance. When the body is not in the true vertical and horizontal planes, the body will attempt to compensate for the stress caused by the imbalance. The resulting effect of imbalance is pain and discomfort.

Body imbalance and distortion result from stretched nerves which over-innervate (overload) the nerve pathways, causing the large anti-gravity muscles (extensors) to contract, a type of spasticity. The spine and pelvis twist and tilt from the normal position, and one leg shortens.

If the atlas is displaced, it must be corrected to normal position before the spinal imbalance symptoms and leg shortness are relieved. The atlas is adjusted according to a formula that is computed from the analysis of your x-rays. If the atlas is corrected to normal position, the entire spinal column will return to its true vertical axis, permitting normal neurological functioning and alleviation of the patient's stress, pain, and discomfort. No step in analysing your problem is left to chance, and each stage of the process is associated with some previous form of measurement.


Symptoms are not always accurate indicators of a patient's health. The doctor must be guided by the biomechanical measurements taken during the first examination and by the x-ray analysis. The x-rays determine if the atlas has displaced to an abnormal position. The x-rays also tell the doctor how to adjust the atlas to its normal position. The doctors skill in the adjustment is based on a formula taken from mathematics and physics. The doctor will direct a slight but controlled pressure through the atlas from a bone in the heel of his hand (pisaform). It is at this precise moment that the atlas moves toward its normal position that the adjustment takes place (see Fig. 3).


Correction of the atlas displacement (subluxation) must take place before results occur. No individual can be healthy until his bodily stresses are removed and his nervous system works normally. After the adjustment you may not immediately feel better, because nerves heal at approximately one-eighth inch a month. You might feel some discomfort in the neck region as the vertebrae, ligaments, and muscles assume their new position. You may even feel new and different sensations throughout your body because symptoms arise from tissue changes, not from diseased tissue alone. Remember that a proper adjustment (correction) must take place before the healing process begins, and it is also important to remember that, once the corrections are made, it is up to your body how fast you improve. In most cases, the condition the patient is in when he first enters the office is a result of a condition he had for many years.

Most patients will notice a change in their symptoms within two weeks after the adjustment. At the end of six months, your health problems should be gone.

Many patients are not aware of the added benefits from corrective adjustments: the restoration of misaligned vertebrae to normal position, improved posture because the body's center of gravity in the pelvis and the gravital line are realigned, removal of the unequal stress on the discs between the vertebrae (protecting them from early disintegration and possible rupture), and removal of undue strain from the joints of the skeletal framework. As a result of proper adjustment, your general health should improve.


Possibly the most important phase of this service is the compliance period. Compliance means to follow the directions of the doctor until he releases you from service. Sometimes the patient will decide that he is feeling better and further visits are not necessary. Usually this happens at the time that the adjustment is about to hold, or stabilize. By not complying with the doctor, previous benefits can be lost. It is the feeling of the doctor that if the patient is not willing to cooperate until released, it is better for both patient and doctor that the patient not start services. The doctor can not control the patient's progress, and unforseen problems arise if the patient does not cooperate.

The reason for this need for patient compliance is that, while the doctor is concerned with how the patient feels, symptoms are not always reliable indicators of the patient's progress. Therefore, during the stabilization period, the doctor needs to "measure" the progress of the patient in an objective manner. The patient may feel "good" but he might have lost the adjustment, or he may feel "bad" but still be in adjustment.

After the adjustment the patient is asked to follow a few rules which will help stabilize the neck during the healing process. Excessive physical activity, such as jogging, water skiing, tennis, golf, swimming, and all contact sports should be avoided. Leisure activities, such as sleeping in a car or chair, lying on the stomach or sleeping on the stomach, or watching television while lying down, turning the head while backing your car, and looking up or raising your arms above your head, can be detrimental. Work activities, such as continued looking up (painting, washing cabinets, windows), lifting or assuming unusual positions (dentist, mechanic, farmer) can also be harmful to the stabilization of your adjustment.
