The invention relates to medicine, namely to diagnostics of the organism, and can be used for the detection of transverse and longitudinal platypodia in schools, military, hospitals, and other medical and educational institutions.

Timely detection of flat feet is very important for treatment and corrective procedures in the early stages of this disease, only then will provide high efficiency of treatment. In addition, diagnosis of flat feet is of great importance in sports medicine to monitor the condition of the foot athletes and prediction of risk of injury to the foot.

As a prototype of the chosen method of assessment of the foot (complex planography), which consists in taking prints (pentagram) plantar surface of the feet with the help of a special device (pantograph) and the subsequent processing of these prints, grafico-calculation method [1].

However, the known method does not provide an acceptable rate of surveys and high diagnostic accuracy, because the footprint method prototype obtained using makanya foot in special paint, and then get colored imprint of the foot on the paper. In addition to the inconvenience of the subject associated with staining his feet, diagnostics status of the foot in question is the method associated with the consumption of ink and has a high probability of obtaining an incorrect result associated with improper foot position on plantigrade.

Object of the present invention is to improve diagnostic accuracy and speed surveys the stop person. The invention is aimed at improving the diagnostic accuracy of the examination of the condition of the human foot, as well as minimizing the time of diagnosis and cost of consumables per cycle of the survey. This is achieved by the fact that the foot prints get on a specially fortified flatbed scanner, capable of withstanding the weight of the person, the treatment of foot prints are produced using a special program that allows you to automate the survey process, resulting in increased objectivity and uniformity of diagnosis, there is no need for consumables (paints for coloring stop) and provides for high speed tests.

The difference of the present invention is that for the first time are encouraged to use to get planographics images specially fortified flatbed scanner, capable of withstanding the weight of a person. This ensures high quality planographics shots, reliability and objectivity of the survey.

The invention is illustrated by drawings: figure 1 shows the window with the resulting scan is by images of both feet; figure 2 shows sample markup foot to diagnose her condition; figure 3 presents the analysis of the image of the foot investigated; figure 4 shows the conclusion generated by the diagnostic program according to the results of calculation of the indicators that determine the state of the foot.

The present invention includes the following steps.

1. The subject puts alternately left and right foot on the surface of specially fortified scanner in the position of the main anatomical hours in which a person's weight is distributed evenly on both feet.

2. Scan the sole of the foot. The window with the resulting scan images of the foot shown in figure 1.

3. The operator produces the markup image of the foot in accordance with the example shown in figure 2 (left part of the window). To ensure the objectivity of the diagnosis and of the independence of the results from the random artifacts operator selects with the mouse only key point of the image, the program conducts direct between points, and calculates the position of the reference points on the image of the foot. This sample markup stops flashing point is indicated by the following point that should be emphasized in the picture of the foot. In addition, in the right part of the window displays podskazka current mark point.

The window with the image analysis of the foot shown in figure 3. The analysis algorithm is the following.

The operator selects with the mouse on the image of the foot rearmost point of the heel imprint - point d

The operator selects with the mouse on the image of the foot at the front point of the thumb point P.

The operator selects with the mouse on the image of the foot at the front point of the second finger - point P'. After that, the program measures how far is the greatest - DP or DP'. The greatest distance is the length of the foot print.

The operator selects with the mouse on the image of the foot, the point corresponding to the head of the first metatarsal bone point A. After that, the program draws a direct RA.

The operator selects with the mouse on the image of the foot, the point corresponding to the head of the fifth metatarsal - point Century After that, the program draws a direct AB.

The operator selects with the mouse on the image of the foot most protruding laterally of the point of the heel - point C. After that, the program carries out direct sun and lowers her a perpendicular from point D, thereby obtaining point E. point E on a straight line BE the program lays segments, 0.30, between 0.46 and 0.60 length of the print. Of the points found, the program recovers the perpendiculars to the line BE straight UU', VV' and WW'.

The operator selects with the mouse on the image of the foot Naib is more prominent on the left point of the heel - dot With'. Then the program finds the middle of the direct SS' and refers to her by the point F. Similarly, the program finds the middle of the straight line AB and designates it a point Z. then the program draws a direct FZ - conditional axis of the foot. In addition, the program conducts direct'AN and BR, parallel to relative axis of the foot. From point C' to direct UU' program conducts perpendicular - direct S N.

The operator selects with the mouse on the image of the foot point of the connecting tangent to the contour of the heel and direct UU' point of K. then the program draws a direct S K.

The operator selects with the mouse on the image of the foot point between the bases of the 3rd and 4th toes point G. After that, the program draws a direct FG.

The operator selects with the mouse on the image of the foot point, connecting the center of the footprint with direct V to the left - point V'. Then the program finds the point of intersection of lines FZ and FG with direct VV' - respectively the points X' and y

The operator selects with the mouse on the image of the foot point, connecting the center of the footprint with direct V to the right - the point X.

The operator selects with the mouse on the image of the foot at the front point of the fingerprint of the fifth finger - point Q. then the program draws a direct BQ.

After partitioning of the foot, the program calculates the diagnostic indicators to determine the status of the foot.

The condition of the anterior accelastudy characterized by the following parameters.

The angle at the 1st finger (<NAP). If <NAP under 18°medial part of the foot is normal. If <NAP more than or equal to 18°that is transverse raspletanie.

The angle at the 5th finger (<QBR). If <QBR less than 12°lateral part of the foot in the norm; if <QBR is greater than or equal to 12°that is transverse raspletanie.

The state of the middle Department of the foot is characterized by the index K, where K=X/Y, X is the distance between the points X and X', Y - distance between points V and Y.

The degree of longitudinal platypodia is determined by the parameter as follows:

when It≤0,5 - foot hollow;

at 0.5<To≤1,10 - foot with a normal arch;

when 1,10<To≤1,20 - foot with a low arch;

when 1,20<To≤1,30 - first degree of flatfoot;

when 1,30<To≤1,50 - second degree of flatfoot;

when K>1,50 - third degree flat feet.

The state of the rear of the foot section is characterized heel angle HC'K: if the angle HC'K is greater or equal to 5°the condition of the foot in normal, if the angle HC'K less than 5°, foot flat.

SUBSTANCE: method involves taking imprints from upper and lower jaw for manufacturing plaster jaw models. The lower jaw plaster model is used for measuring mesiodistal dimensions of twelve teeth: 46-41 and 31-36. Particular tooth lacking, its dimensions are calculated using percent proportions from mean dental parameter values table. Individual general projection length norm is calculated for upper and lower jaw using formulas; Lpo=0.39*Σ12 and Lpu=0.35*Σ12, where Lpo and Lpu are the individual general projection length norms of lower and upper jaw, respectively; 0,39 and 0,35 are indices describing relationship binding mean general projection length of lower and upper jaw to mean sum of mesiodistal dimensions of twelve teeth(46-41 and 31-36) of lower dental row in persons having physiological occlusion and permanent teeth dimensions within the limits of mean values, respectively; Σ12 is the sum of mesiodistal dimensions of twelve teeth(46-41 and 31-36) measured on plaster model. Individual norm values of general upper and lower jaw projection length are compared to corresponding actual values measured on models. The values coinciding, conclusion is drawn concerning normal sagittal dimensions of denture. Difference being positive, increase in sagittal denture dimensions is considered to be the case. The difference being negative, reduction of sagittal denture dimensions is considered to be the case. Actual projection length values of the anterior segment are additionally determined by taking measurements from upper and lower jaw models, with distance between mesial point on labial approximal surface of incisor in vestibular position and point of intersection of line joining contact points of canine tooth and the first molar on the left and right side to median line of the upper jaw. Distance between contact point of lower central incisors cutting surfaces and point of intersection of line joining contact points of the first and the second premolars on the left and right side to median line of the lower jaw. Individual general projection length norms are calculated for upper and lower jaw anterior segment using formulas: lpo=0.16*Σ12 and lpu=0.17*Σ12, where lpo and lpu are the individual general projection length norms of lower and upper jaw anterior segment, respectively; 0,16 and 0,17 are indices describing relationship binding mean general projection length of lower and upper jaw anterior segment to mean sum of mesiodistal dimensions of twelve teeth(46-41 and 31-36) of lower dental row in persons having physiological occlusion and permanent teeth dimensions within the limits of mean values, respectively; Σ12 is the sum of mesiodistal dimensions of twelve teeth(46-41 and 31-36) measured on plaster model. Individual norm values of general upper and lower jaw anterior segment projection length are compared to corresponding actual values measured on models. The values coinciding, conclusion is drawn concerning normal sagittal dimensions of denture. Difference being positive, increase in sagittal dimensions of anterior denture segment is considered to be the case. The difference being negative, reduction of dimensions of anterior denture segment is considered to be the case.
