Abstract: A stand for reproducibly ascertaining the posture of a free-standing human being, includes a base plate, a central bending post and a standing plate affixed to the central post; the standing plate exerts tension upon the central post particularly when a person stands on the plate; strain gauges are affixed to the central post and the stand as a whole is improved by providing a pair of foot plates placed side by side, each foot plate is supported by a pair of rotatable tubular elements or rings on the stand plate, for elevationally adjustably mounting the respective foot plate; all these elements are driven in unison by a belt such that one foot plate is raised while the other one is lowered and vice versa.
