The aforementioned measurements are taken on each individual upon en- 
trance to the University in the fall of the year. If he is assigned to the corrective 
classes, as a result of the initial postural analysis, a second photograph, together 
with the measurements as indicated above, is taken. Since the fall of 1952 
slightly over 3,000 men have entered the Freshman class (about 1,000 each 
fall). À little over 60 per cent have been assigned to the classes in body me- 
chanics. The basis on which these assignments are made is as follows: 
GENERAL OVER-ALL POSTURE: 
/1—good body mechanics (good alignment with no observable deviations 
in any segment of the body) 
42—fairly good alignment with more pronounced deviations in specific 
segments of the body 
#3—poor body mechanics (poor alignment with very pronounced deviations 
in specific segments of the body). 
Alignment in specific regions of the body, i.e., head and neck region, kyphosis, 
lordosis, etc. are based on: 
1. mild deviation from good alignment 
2. moderate deviation 
3. pronounced deviation. 
Objective measurements as determined from the photographs (and the 
slides since the PhotoMetric equipment was installed) indicate the following: 
1. HEAD AND NECK POSITION 
a) Angle T7H (“c” under Side View Image) indicates that an angle of between 60 
and 65 degrees denotes a fairly good position of the head and neck. If the angle is 
between 55 and 59 degrees there appears to be a slight tilt forward. If the angle 
is between 51 and 54 degrees the tilt is moderate, and an angle below 50 degrees 
shows a very pronounced forward tilt. 
b) hdt (horizontal displacement—‘‘a’’ under Side View Image) appears to be closely 
related to the angle in the neck region in that the greater the displacement the 
sharper the angle. 
2. SHOULDER POSITION 
The overhead image appears to be the better means of determining the forward tilt 
of the shoulder girdle. Using the points of the acromio-clavicular joints together with 
the spinous process of the seventh cervical vertebra a definite angular measurement 
of the position of the shoulders can be determined. From measurements, recorded if 
this angle is less than 150-155 degrees, a forward tilt of the shoulders is apparent.
