The foot was divided into 10 regions containing the heel; the medial and lateral midfoot; the first, second, third, fourth and fifth metatarsals; the great toe; and the second to fifth toes. The novel Emed-X system used the software with the automasking function, where the first eight of the aforementioned regions were drawn automatically, while the toe regions had to be drawn manually due to deformity of the toes, especially after microsurgical great toe-to-hand transfer. Four clinically relevant parameters were investigated including the PP (kPa), CT (ms), CA (cm²), FTI (N s), and PTI (kPa s).
