Abstract
Sizes of the girdle on the market are so limited that we cannot choose the proper one freely. However, if we can select girdles of the appropriate materials the defect in fitting might be compensated to some extent.
From this point of view, we carried out the pressure tests, wearing the girdles of an equal design and size but of four different materials from soft to hard.
It was proved that the pressure exerted by girdles of the same size increased according to the material in order of soft, medium, and hard.
Also it was quantitatively made certain that the dependence of the girdle pressure on the size was most remarkable in hard materials.
Therefore, it will be necessary to choose proper sizes especially when the girdle is made of hard materials.
