METHOD FOR REHABILITATION ASSESSMENT OF FINE MOTOR FUNCTION OF THE HAND Russian patent published in 2020 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to functional diagnostics, and can be used for diagnostics of children's neuropsychiatric disorders. Disclosed is a method, in which a range of motion "approach-move away" of the first and second fingers of the paretic hand is measured using a touch panel of a standard tablet computer as a recording device. In order to unify the values of dilution, to reduce the effect of individual anthropometric data, a standardized index of finger digging has been obtained experimentally. It is obtained by dividing the absolute value of the range of dilution of the first and second fingers on the touch panel of the tablet computer by the length of the segment obtained with the difference in the distances X and Y. Distance X is the distance from the styloid process of the radial bone to the tip of the second finger; distance Y is distance from styloid process of radial bone to end phalanx of first finger. Initially, the examined upper extremity should be bent in the elbow joint at angle of 90°, in radiocarpal joint 0°. Initial position for measuring the distance between the first and second fingers of the hand when expanding is the middle physiological position of the hand with finger bending. In this position, the patient is encouraged to put fingers on the surface of the touchpad of the tablet computer with the thumb pad downwards in a state of maximum information and try to maximally spread the fingers apart from the plane of the panel. At that, on the panel automatically, in visual form, the determined distance of dilution between the first and second fingers is output, as well as a standardized indicator which is individual for each patient. In case of central paresis of hand, spasticity is most often observed, in which finger extension and extension is most difficult, and the wrist is often in the condition of flexion contracture. Therefore, the distance of dilution between the first and second fingers obtained by the use of the touch panel is largely correlated with the hand fine motility function. At that, the smaller distance at digestion of fingers, the worse the function of fine motor, and higher indices indicate smaller violations.

EFFECT: invention provides higher measurement accuracy, considerable convenience of operation when examining subjects due to mobility and rate of determining motor deficiency.
