METHOD FOR DIAGNOSING SENSOMOTOR DISINTEGRATION IN STROKE SURVIVORS Russian patent published in 2019 - IPC A61B5/16 

FIELD: medicine.

SUBSTANCE: invention refers to diagnosing functional disorders in patients with cerebral injury, and can be used in neurology for diagnosing sensor-motor disintegration in post-stroke patients. Disclosed is a method comprising using a software and hardware system consisting of a laptop and a program controlled by two joysticks with nozzles imitating everyday skills, performing the test task of combining two figures on the laptop screen as accurately as it can, determining the accuracy of alignment and time from the beginning of the job to aligning the figures. Subject is asked to align as accurately as possible on notebook screen two circles with diameters of 5 cm with thickness of contours of 0.5 cm, located along middle horizontal line at distance of 13 cm between centres, and keep them aligned for 10 seconds in a given region of alignment of circles. When alignment is achieved, determined by absence for 10 seconds of difference in distance between contours of circles is more than 1.5 cm, which is 30 % of diameter of circles. Person being tested is given a feedback in form of a change in the colour of the contour of the circle from black to red. Assignment to test subjects is carried out successively 3 times with application of nozzles imitating everyday skills. Task with each nozzle is limited by time of 5 minutes. Intervals between jobs filled with various distractions are 5 minutes. Based on the assignment results, an integral index is calculated by formula: I = 10×t_x/47 + a_x/0.5, where t_x is the match time; a_x is the accuracy of alignment. If the integral value is less than 9.0, the results are considered to be normal, interval from 9.1 to 15.0 corresponds to apraxia, if the value is more than 15.1 - to paresis.

EFFECT: invention provides more accurate diagnosis of sensomotor disintegration in post-stroke patients.
