AN X-RAY STUDY OF THE DIAPHRAGM
Part I Its Correlation to Body Mechanics in Children
LLOYD T. BROWN M.D.
1. The position and the amount of excursion of the diaphragm is affected by the shape of the chest.
2. In the case of a chest which is used in the position of expiration, the common one in faulty body mechanics, not only is the diaphragm in a lower position in the chest, but also there is less excursion.
3. In the case of a chest which is used in the position of good body mechanics, the diaphragm is in a higher position in the chest and there is a greater excursion of the diaphragm.
4. Accompanying these changes, there is also an improvement in the general condition of the patient as a whole,an increase in weight, an increase in the vital capacity, and an improvement in the body mechanics.
