Characteristics of the instrument

A modification of the "classic" Hrdlička's thoracometer, the instrument primarily serves for easy determination of the length of the foot. The device consists of an aluminium square section rod fitted on both sides with a millimetre scale (0 - 400 mm). The rod carries 100 mm long shoulders made of hard plastic. The width of the arms (30 mm) greatly facilitates the localization of the pternion and the acropodion.

A groove in the sliding arm enables reading the values from both sides of the instrument (to determine the length of both feet, simply turn the instrument over). While measuring the foot length, the subject stands with his/her feet slightly apart, with the weight distributed evenly on both legs. The axis of the instrument is parallel to the inner edge of the foot, the bent toes need to be pressed against the floor.
