Abstract
From one length and four widths of the lower limb, the formula of the lower limb was originated, of which the quantitative measurements were:
1) Length of lower limb: iliospinal height +Symphysion height/2,
2) Width I of lower limb: Width where the thigh is largest in circumference,
3) Width II of lower limb: Width where the thigh is smallest in circumference,
4) Width III of lower limb: Width where the leg is largest in circumference.
5) Width IV of lower limb: Width where the leg is smallest in circumference. From these five quantitative measurements, the following six indices were derived:
I) Lower limb index I (= Width I of lower limb. 100/length of lower limb),
II) Lower limb index I I (= Width II of lower limb. 100/length of lower limb),
III) Lower limb index III (= Width III of lower limb. 100/length of lower limb),
IV) Lower limb index IV (=Width IV of lower limb. 100/length of lower limb),
V) Lower limb width index A (= Width III of lower limb. 100/width I of lower limb),
VI) Lower limb width index B (= Width IV of lower limb. 100/width II of lower limb) .
These indices were sought from the anthropological ages of many instances of men and women, and centered around arithmetical averages of indices; six types of classifications were made with considerations for standard variations.
These types were symbolized simply from one to six which in turn were charted in parallel arrangements in the order of indices I II III IV A B, producing a form which was named the First Formula of the Lower Limb.
