Diagram 6 shows by the dotted outline the form of a girl, age thirteen, who had not worn corsets. The extreme shoulder sag was compensated by the thrusting forward of the abdomen and the drooping of the head. The spine was straightened, head lifted, abdomen supported, chest raised and brought forward, as indicated by the black outline, by the corrective fitting of the corset.
The fundamental principle underlying such a correction is in producing a sustained normal position of the pelvis, forming a firm base for the spine, which in turn supports the upper portion of the body. Lifting the abdomen with a firm pressure from below lifts the chest and head and straightens the shoulders. Every detail of this correction promotes the healthful development of the body, and no injury can result from fitting young girls with such corsets when faulty postures cannot be corrected by exercises. The corsets must give, first of all, actual abdominal support and no pressure whatever around the thorax, though normally correct lines of the back must be sustained by firm and careful fitting.
