Abstract

We measured in this study the angle of the forced leaning posture of a human body, and investigated the relation between its angle and the capacity of a human body to maintain the erect posture which is his basic one.<br>On analysis of CSFS in he cases of an "active" and a "passive" leaning posture, it gave the following results. ['CSFS' is short for 'contact surface of a foot sole'.]<br>1. The degree of restoration in CSFS when resuming the previous erect posture is considered to be an important criterion in measuring the ability to stand upright.<br>2. Both in "active" and "passive" conditions, the fructurations are most remarkable in toes and the central part of the sole, so it is presumed that those parts are functioning dynamically as a factor of adjustment.<br>3. Comparing "active" and "passive" conditions, CSFS is mostly larger in "active" than in "passive" conditions.<br>4. When the subject leans forward and backward to the utmost, both in "active" and "passive" conditions, CSFS is remarkable difference between right and left, so laterality can be recognized in this case.
