# Odometry

Odometry - method research feet for objective evaluation (in the figures) the state of their longitudinal vaults. Odometry is a doctor-orthopedist by means of a special device - stopoper or more simple way, with the help of a compass, ruler and protractor, which make measurements of the foot and Ovcharka her soles on paper. In the result of measurements and calculations displays "photometrically index, characterizing the state of the longitudinal arch; flat feet below 29, when excessively pronounced arch (excavation feet) above 31.

Odometry - method of measurement of the foot, reflecting elastic vibrations arc longitudinal arch of the foot.

 Fig. 1. Measurement of the foot pedometers Friedland: 1 - length; 2 - high; 3 - width. Fig. 2. Measurement simplified pedometers Friedland: 1 - the length of the foot; 2 - the height of the foot.

The method and light technique of measurement stoponerror-pedometers proposed M. O. Friedland (Fig. 1 and 2). Possible odometry and without Stopera: the subject put on the sheet of paper so that his feet formed a right angle with respect to the lower legs; the height of the foot determined by measuring the compass distance from the top surface of the scaphoid (palpated on cross your finger in front of the ankle bend to the floor. Each stop they outline on paper with a pencil, holding it at a straight. The contour is measured with a ruler (in mm) of the length of the foot from the tip of the first finger up the back edge of the heel. Data about the height of the foot is multiplied by 100 and divided by the length of the foot (photometrically index).
Index foot in norm fluctuated from 29 to 31. The figures above 31 talk about excessive increase the longitudinal arch (excavation), below 29 - about the flattening of the code (flat feet). Stoponerror or around the edge of the foot and the indexes of the width of the foot (in the narrow and broad parts). With a protractor on the same circuit can be measured and angle adduction of the foot (on the border of her front and back offices)and the corners of flexion and extension of the foot, which protractor should be made directly to the side surface of it, and to determine the angles supination and pronation is to the rear surface of the foot.
When the transverse platypodia (see) there is an increase in photometrically width in relation to the length of the foot to 42% and more (instead of the normal 40%).
