Description

Cognitive Perceptual Assessment System for Evaluation of Driving Ability of Persons with Brain Injury}

The present invention relates to a cognitive perceptual evaluation system, and to a cognitive perceptual evaluation system for judging the driving ability of the brain-injured disabled by accurately evaluating sensory perception and cognitive functions of the disabled.

In Korea, the evaluation of driving ability is mainly focused on the evaluation of motor skills. Even though driving is a complex interaction between cognitive function, perception ability, motor skills, and environmental factors, only the physical ability evaluation of the disabled's driving ability is performed. This lacks objectivity.

And, for the purpose of objective evaluation, there is a method of evaluating the actual driving by using the actual vehicle such as the intestinal function evaluation, but the evaluation through the road driving takes a lot of time and requires a modified car and a special driving instructor. It is not implemented properly because it is expensive and carries the risk of an accident during evaluation.

In addition, in the current disability driver's license system implemented in Korea, a person with a disability who does not have a driver's license must go through a disability driving ability test, a theory test, and a practical test. If a patient passes the exercise test, the license is reissued. Therefore, the disabled have no procedure to objectively evaluate their brain function.

However, people with brain injury due to cerebrovascular disease or trauma can have a great influence on their driving ability because problems can occur not only in physical function but also in cognitive function, perception function, communication and emotion. There is a possibility of a safety accident. Therefore, it is urgent to prepare measures to safely drive a car after a disability, such as the development of a system for evaluating autonomous driving ability for people with a brain injury accompanying such a disability even if driving was possible before.

The evaluation control unit 120 receives and stores various data necessary for driving the cognitive perceptual evaluation system 100. If the data storage space is enormous, it may be provided with a separate database 121 as shown in FIG.

In addition, while receiving and storing the user input information from the user input unit 110, and controls a plurality of cognitive perceptibility test content for determining the subject's driving ability to be provided to the examinee, corresponding to the provided cognitive perceptibility test content And comparing the test information of the evaluator inputted through the user input unit 110 with the previously stored answer information to calculate evaluation result data (Yw: CPAD score) for each test subject's cognitive perceptibility test content. do.

In addition, the evaluation controller 120 compares the calculated evaluation result data with preset inspection determination reference data to determine whether the evaluator passes or fails, and the display unit 130 controls the evaluation controller 120. In response to the signal, whether or not the evaluator passes or fails is displayed on the screen window 131a.

Here, the cognitive perception ability test content is displayed on the screen window 131a through the display unit 131 of the display unit 130 and is a test item for testing the driving ability of the brain-injured person with a disability. As shown, Depth Perception Test, Sustained Attention Test, Divided Attention Test, Stroop Test, Digit Span Test ), Field Dependence Test, Trail Making Test A, and Trail Making Test B.

The answer information refers to data about input information for obtaining a valid evaluation score for each cognitive perception test content.

In addition, the evaluation control unit 120 compares the testee's test information and pre-stored answer information with each other, and includes a plurality of variables including a positive response number (positive response number) and a reaction time of the test information for each cognitive perceptual ability test content. (V1 to V10) are measured, and the evaluation result data is calculated by applying each measured variable to preset evaluation criteria data.

 In addition, the evaluation result data (Yw: CPAD score) means a result value that is set in advance in order to determine whether the evaluator passed or failed, the evaluation criteria data is a clinical trial so that reliability can be given to the evaluation result data Means the weight value calculated by statistically analyzing the results obtained through.

In addition, the plurality of variables V1 to V10 are designated items to be applied to the evaluation criteria data that may affect the cognitive and perceptual ability, and include the positive response number V1 of the distance perception ability test and the caution. Positive response number (V2) of the persistence test, positive response number (V3) of the divisional force test of the attention, positive response number (V4) of the stroop test, digits of the speaking test according to the number (V5), and positive response number of the intestinal dependence test (V6), the reaction time (V7) of the distance perception test, the reaction time (V8) of the stroop test, the reaction time (V9) of the trail making test A, and the reaction time of the trail making test B ( V10).

Here, the evaluation criteria data, while statistically analyzing the results obtained through clinical trials, and based on the evaluation result data for each cognitive perceptual test content for the brain injury impaired person (A) of a predetermined number of people By extracting the basic statistics of each variable by standardizing the average of the measured variables of the brain injury impaired person (A) to 50 and the standard deviation of 10, and based on the extracted basic statistics, Principal component analysis is performed to find principal components that can explain the major variances to obtain eigenvalues, cumulative explanatory ratios, and principal component coefficients.The first principal component (Y) of the obtained principal component coefficients is calculated to maximize variance It may be set to a value Yw obtained by adjusting the sum of the weights for the first principal component Y calculated to be 1.

Hereinafter, the evaluation results of the cognitive perception test content performed on 101 people who had a driving ability evaluation by participating in the driving clinic of the National Rehabilitation Center as a person with a brain injury such as a brain injury or a brain tumor caused by cerebrovascular disease By setting the evaluation data based on the data (clinical experiment data), a method of setting the evaluation data will be described.

First, as shown in the following [Table 1] as the basic statistics for each of the measured variables of the brain impaired people (A), the average, standard deviation, coefficient of variation, skewness, and the like are extracted.

[Table 1]: Statistical analysis of each variable

Here, the items having a large deviation from the average are trail making test A and trail making test B, etc., and the degree of distortion is within ± 2, and the distribution form of the data does not deviate greatly from symmetry.

Subsequently, the test items of each variable are different from each other in terms of the number of reactions, reaction time, etc., so that the unit and the unit of the variable are the same. The standardization is performed so that the mean is 50 and the standard deviation is 10.

[Table 2]

Based on the extracted basic statistics, the principal component analysis is performed to search for principal components that can explain the main fluctuations of each cognitive perceptibility test content, thereby obtaining eigenvalues, cumulative explanatory ratios, and principal component coefficients. The first principal component (Y) of the coefficients maximizes the variance to yield the first principal component (Y) as shown in Equation 1 below.

[Equation 1]

Y = 0.288V1 + 0.241V2 + 0.347V3 + 0.346V4 + 0.201V5 + 0.337V6 + 0.159V7 + 0.375V8 + 0.368V9 + 0.403V10

Here, the first principal component Y represents the contribution of each variable as a weighted average form of each cognitive perception test content, and adjusts the sum of the weights to 1 to obtain a value (Yw) obtained as shown in Equation 2 below. The CPAD score of the cognitive perceptual evaluation system 100 according to the preferred embodiment of the present invention is set to the evaluation criteria data.

&Quot; (2) "

Yw = 0.0940 V1 + 0.0787V2 + 0.1133 V3 + 0.1130V4 + 0.0656 V5 + 0.1.99V6 + 0.0519 V7 + 0.1223V8 + 0.1198 V9 + 0.1315V10

In addition, as a result of analyzing the overall scale reliability of the clinical trial data, the Cronbach α value was 0.85, which reflects the internal reliability between the driving ability measurement variables. Table 3 was as follows.

[Table 3]

In addition, the mean correlation coefficient between each variable was r = 0.37, indicating that the variables were generally correlated with each other, and the correlations between the individual variables were as shown in Table 4 below.

[Table 4]

In addition, in the case of variable reliability, some variables may be less correlated with the driving ability of the brain-injured handicapped. To determine this, we analyzed the degree to which each variable contributed to the CPAD total score. B, trail making test A, and stroop test response time, positive response, intestinal dependence test, and attention split test showed the same correlation with CPAD total score.

In particular, the response time of the trail making test B and the stroop test was r = 0.86 and r = 0.80, which contributed the most to the other variables, whereas the response time of the distance perception test and speaking according to the number were r = 0.34, r = 0.43, etc., it is confirmed that the CPAD total score and correlation is relatively low compared to other variables.

In addition, as a result of analyzing the validity of the test result data for each cognitive perception test content, the CPAD score according to the results of intestinal function evaluation summed the scores of all items and averaged the CPAD scores of 101 people with disabilities The score was 49.68 ± 7.25. Among them, 46 patients passed the intestinal function test and 55 failed. The mean score of the passing group was 51.67 ± 5.53, and the mean score of the failing group was 44.30 ± 8.44. (P = 0.0001)

CPAD scores for each category were: positive response number for attentional division test, positive response number and response time for stroop test, positive response number for speaking test, field dependence, response time for distance perception test, trail making test A and trail making test B In the eight items of the response time of the pass compared to the rejection group showed a significantly higher score as shown in Table 5 below.

[Table 5]

In addition, as shown in Table 6 below, the 95% confidence interval for the CPAD score of the pass and fail groups based on the gut function evaluation was found to be 50.59 to 52.75 in the pass group and 42.67 to 45.93 in the fail group. . CPAD estimated scores using the 95% confidence intervals above can be judged as 53 or more points for the pass group and 42 or less points for the failing group, and 43 to 52 points can be defined as the boundary group. The positive and negative predictive rates were 90.7% and 50.3%, respectively.

[Table 6]

On the other hand, the display unit 130 is a component for displaying the test item and the evaluation result data for the cognitive perceptual ability test content to the outside according to the control signal of the evaluation control unit 120, shown in Figures 1 and 2 As described above, the display unit 131 for displaying the inspection item and the evaluation result data on the screen window 131a, the speaker 132 for outputting sound associated with the inspection item, and the evaluation result data and personal information are printed. It may be provided including a printing unit 133.

Next, the operation principle of evaluating the cognitive perception ability to determine the driving ability of the evaluator with the brain injury disabled in the cognitive perceptual evaluation system 100 according to an embodiment of the present invention will be described.

First, the evaluator knows how to perform a test for a plurality of cognitive perceptual test content through the sound output to the manager or the speaker 132, joystick 111, keyboard 112, mouse 113 ) And the user input unit 110 that can be operated by the touch panel, and inputs personal information such as name, age, gender, contact, address, and the like.

The evaluation control unit 120 stores the input personal information in the database 121 and controls the evaluation result data for each subject to be evaluated later to be matched and stored.

When the evaluator's personal information is completed, a plurality of cognitive perceptual test content for determining the evaluator's driving ability, that is, a test item for testing the driving ability of the brain-disabled person, is a distance perception test. Sustained Attention Test, Divided Attention Test, Stroop Test, Digit Span Test, Field Dependence Test, Trail Making Test A (Trail Making Test A) and Trail Making Test B (Trail Making Test B) are displayed on the screen window 131a of the display unit 131 in a predetermined order and controlled to be provided to the examinee, and corresponding to the provided cognitive perception test contents. Each of the subject's perceptual perception ability by comparing the test information of the evaluator input through the user input unit 110 and the previously stored answer information The evaluation result data (Yw: CPAD score) for the output test content is calculated and displayed on the screen window 131a or controlled to be output through the printing unit 133.

At this time, the evaluation control unit 120 compares the test information of the evaluator and the pre-stored answer information, a plurality of variables (V1 to V10 consisting of the number of positive reactions and the reaction time of the test information for each cognitive perceptual test content) ), And the evaluation result data may be calculated by applying each measured variable to preset evaluation criteria data.

Herein, a specific test execution method will be described for each test item of the cognitive perceptibility test content. First, the distance perception test is performed in two vertical long lines arranged on the screen window 131a of the display unit 131 in the vertical direction. And a plurality of horizontal lines arranged at irregular intervals on each vertical line, and horizontal bars arranged horizontally between the two vertical lines and reciprocating in the vertical direction, respectively. By answering that the inspection information is input through the user input unit 110 at the timing when each horizontal line disposed on the long line is located on the same horizontal line, the ability to recognize the distance during driving can be measured.

In addition, in the distance perception ability test, the two vertical long lines are fixed in a shape that gradually becomes narrower toward the upper space between the two vertical long lines to be displayed on the screen window (131a) can provide an image of the perspective of the actual road. The degree of difficulty of the inspection can be adjusted by adjusting the speed of reciprocating movement of the horizontal line.

For example, as shown in FIG. 3, a horizontal line of '↔' forms a reciprocating movement up and down between two vertical lines narrowing upward on both sides of the screen window 131a, and the assessor The input button 111b of the joystick 111 may be pressed at a timing at which each horizontal line arranged in two vertical lines forms a straight line.

The distance perception test is performed 20 times at a slow speed, 20 times at a high speed after three exercises to measure the number of positive reactions and reaction time.

The attention persistence test, a plurality of identical characters are irregularly arranged on the screen window 131a of the display unit 131 and random characters are rotated at predetermined time intervals, and the user is rotated at the timing at which the characters are rotated. By answering that the inspection information is input through the input unit 110, it is possible to measure the continuous capability required for driving.

For example, as illustrated in FIG. 4, eight characters formed in a 'ㅂ' shape are irregularly disposed on the screen window 131a, and the subject is allowed to observe the screen window 131a as a whole. When the direction is changed, the input button 111b of the joystick 111 is pressed, and the character may be set to change direction at an interval of 3 seconds. Attention persistence test is performed 40 times after three exercises to measure the number of positive reaction.

The attention dividing force test includes arranging a plurality of figures having a plurality of sides in a circumferential form on the screen window 131a of the display unit 131, and randomly changing one side of an arbitrary figure at a predetermined time interval. And the inspection information indicating a direction corresponding to the direction of the disappeared side of the arbitrary figure is inputted, thereby distributing a certain level of attention to several objects at the same time while driving, thereby changing the information of the object. The ability to extract can be measured.

For example, as shown in FIG. 5, 10 small squares are placed on the screen window 131a and one side of the square is randomly disappeared. When disappearing, the joystick 111 can be moved to the left side and the right side can disappear to the right side. In addition, the attention splitting force test is performed 40 times after the three trials to measure the number of positive reactions. In addition, a predetermined sound effect (for example, 'Ding') is randomly provided between the tests, and when the test information corresponding to the sound effect is input in response to the visual stimulus and in response to the auditory stimulus, the answer is measured as the answer. .

In the stroop inspection, one letter among characters having a meaning of red, yellow, or green is randomly arranged on the screen window 131a of the display unit 131, and the same as or different from the meaning of the arranged character. Colors are displayed, and when random letters are displayed, the answer is input that inspection information indicating color corresponding to the color of the letters is input regardless of the meaning of the displayed letters. The ability to adjust can be measured.

For example, as shown in FIG. 6, the letters written as 'red', 'yellow', and 'green' are presented in the same or different colors as the meanings of the letters, so that the color of the letters is irrespective of the meaning of the letters presented. When the color of the presented text is red, the joystick 111 can be moved to the left, green to the top, and yellow to the right. In addition, the stroop test is performed 40 times after three exercises to measure the number of reactions and the reaction time.

The speaking test according to the number, through the speaker 132 outputs a random number consisting of a plurality of numbers from 0 to 9 combined, and outputs a combination of numbers by a plurality of digits, the combined number is Short-term memory can be tested by answering that the test information indicating the number corresponding to the combined number after the output is input.

For example, using the numbers 1 to 9, the speaker 132 presents the number as a voice, and the evaluator listens to and remembers the number and presses the number plate of the keyboard 112. The test is performed twice at each digit and the most memorized digits can be measured.

The field dependence test displays an arbitrary first shape centered on the screen window 131a of the display unit 131 and a plurality of lines irregularly arranged inside the first shape, and the plurality of lines When the second figure having a predetermined shape is displayed within the arbitrary first shape while being irregularly arranged, the answer is that the predetermined inspection information is input through the user input unit 110. Measure their ability to perceive

For example, as illustrated in FIG. 7, a figure composed of many suns is drawn in a large rectangle (first figure), and a square (second figure) of a designated size is found therein to have a square, and the joystick 111 is present. To the left, or to the right if there is no square. The intestinal dependency test measures the number of positive reactions by repeating 40 times after three trials.

The trail making test A displays a predetermined number of consecutive numbers on a screen window 131a of the display unit 131 in an irregularly distributed state, and inputs a continuous number input in a predetermined descending or ascending order. By answering the test information corresponding to the questionnaire, the simple and complex turn is found during driving and visual coordination and visual-motor coordination ability are measured.

For example, as shown in FIG. 8, after the numbers 1 to 16 are mixed and arranged on the screen window 131a, the evaluator clicks from 1 to 1 with the mouse 113. If you are not familiar with), the number of the screen window (131a) in order to point with a finger and instead the examiner can click the mouse 113. In addition, the reaction time for all the clicks in order from 1 to 16 is measured.

Meanwhile, the trail making test B displays a predetermined number of consecutive numbers and a predetermined number of consecutive characters in an irregularly distributed state, and continuously inputs numbers and letters alternately in a predetermined descending or ascending order. It can also be measured by answering the test information corresponding to the numeric input and the character input.

For example, as shown in FIG. 9, eight characters such as go, b, d, d, d, d, d, d, a, d, d, four, five, After placing 8 numbers such as 6, 7, 8, etc., the evaluator clicks the mouse 113 in the order 1 → Ga → 2 → B → 3 → C ... or the numbers and letters on the screen 131a. Pointing the finger directly can measure the reaction time required.

Test items for the plurality of cognitive perceptual ability test content as described above can adjust the difficulty of the test by increasing or decreasing the changing speed of the screen content displayed on the screen window 131a of the display unit 131 for each test item. .

By the configuration and function of the cognitive perceptual evaluation system 100 according to the preferred embodiment of the present invention as described above, the sensory perception function and cognitive function of the disabled with a brain injury can be accurately assessed to drive the disabled The ability to judge the ability to assess the impairment of the brain-impaired person can be objectively evaluated, thereby minimizing the possibility of traffic occurrence of the impaired brain impaired.

In addition, a user input unit such as a display unit 130, a joystick 111, a keyboard 112, a mouse 113, and a touch panel, in which various cognitive perceptibility test contents are displayed in comparison with a conventional evaluation method using a paper and a pen ( 110) and the computerized data is automatically calculated through the data processing device, so that the evaluation result data can be calculated more accurately and objectively, and the evaluation time is minimized.
