1970
|

BJ Palmer and John F. Grostic
|
|

Why take post films?
|
To see how the patient responded structurally to the adjustment,
To help us better manage the patient's case, To help guide us in changing the instrument setting if necessary |

|
straight angle,
the head and neck are at right angles (perpendicular) to the atlas, and the atlas is level |

|
to support the weight of the head
|
|

|
C1 adjustment
|

|
Mission statement
|
To provide excellent compassionate healthcare services to all patients,
To care for the needs of all people with the highest standards of care possible, To promote better health in the world and in our communities through involvement, education, and wellness, To be efficient and cost effective |

|
As it passes through the atlas transverse foramen and continues up into the head, how many 90 degree turns does the vertebral artery take?
|
4
|
|
|
Dr. Roy W. Sweat has not adjusted any vertebra below the atlas since
|
1952
|
|
|
In the Atlas Orthogonal adjusting program, we believe that adjusting the atlas and upper cervical area is not a simple procedure. It is as delicate as
|
the most complicated brain surgery

|
|
Do we ever move the head to take an xray?
|
No
|
|

How do we remove head tilt for the horizontal film?
|
tilt at waist
|
|

|
|
Head clamps
|
used on all AO xray views

Which film has the ASP (atlas sagittal plane) line?
|
SAGITTAL
|
|
|
Which film has the AFP (atlas frontal plane) line?
|

|
|
|
What is the ACD?
|
frontal - angle between center skull ine and atlas plane line, upper angle, = atlas cephalic displacement

Dr. Blair's history
|
suffered from severe asthma is entire life. Medical treatment didn’t help and he was told he would not be able to live much past his early 20s. He was even referred to as a “one time simi-invalid”. His asthma had grown so severe, he was told to move to a more favorable climate. While in El Paso where he met and married Beatrice "Dotty" Kobold on July 20, 1946. Bill was introduced to upper cervical chiropractic by his wife Dotty. Her mother had been a life long friend of a Chiropractor located in Houston.
Reluctantly, due to previous chiropractic shortcomings, he was persuaded to become a patient of Dr. Leon Halsted. He received his first Upper Cervical Chiropractic adjustment at this time. After only a few months of care he noticed a miraculous change in the improvement of his asthmatic symptoms. So much so, that he and his wife packed up their belongings and moved to Davenport, Iowa where he entered Palmer College of Chiropractic.graduated in 1949 |
