Diagram 4. The influence of the corset upon the posture of the individual is a matter far the mast careful study. Corsets in general have little or no corrective influence upon the bad attitude, because the basis of their construction lacks every element required to produce the desired result. But with a corset built fundamentally upon physiological principles the results are positive and easily produced, even in those cases which appear almost hopeless to the commercial corset fitter. The key-note of the correction lies in the abdominal support, which can be obtained with the correct corset even when the iliac crests are more prominent than the abdominal wall.
Diagram 4 shows an extreme case of backward tilt of the upper part of trunk, the balanced weight as usual falling upon the heels. Patient had worn the ordinary type of corset, which fitted only at the waist line and exerted downward pressure at diaphragm. The dotted outline shows body without corsets, and the black outline the corrections made with the physiological corset. No change was made in the regular "ready-to-wear" model of this corset except to reinforce the back with two extra groups of boning down each side of the center.
