Interest of standardization of feet position during 3-dimensional trunk capture

Methods a. Bare skin acquisition. b. Cutaneous benchmark: the first sacral piece (S1), the anterior superior iliac spine (ASIS). c. First acquisition in standard position, feet spread natural, hands at shoulder height into vertical bars, elbows drooping. d. Second acquisition in the same position but with feet in a board position with heels spaced 19cm apart [3]. e. A single operator. f. Measuring the angle S1, ASIS right relative to the horizontal and the angle S1, ASIS left relative to the horizontal on the acquisition software Orten file. An average is taken, the angle (S1, ASIS) relative to the horizontal. g. Comparing 24 samples (20 women and 4 men) with two acquisitions. h. Nine samples (7 women and 2 men) are reacquired three days later.
