Description

  The present invention relates to a system, method, and program for inspecting the skillful movement ability of a finger that captures a qualitative change in finger function as a quantitative change.

  In general, patients who need rehabilitation often have disabilities in their body parts. However, the function will be improved by performing subsequent rehabilitation. In particular, in rehabilitation aimed at living independence, recovery of hand functions, especially finger functions, plays an important role in aiming at independence of daily living activities. Therefore, in rehabilitation, we will improve hand function by using handicrafts, coloring books, puzzles, pegs, etc., aiming to improve meal operation, changing operation and conditioning operation.

  The function of fingers is different depending on the age. Finger function is lower in young children and lower grades, and in older people than in young and middle-aged people. For infants with physical disabilities and older patients at the lower grades, comparing with the finger functions of healthy people at each age is a specific guideline for aiming for life independence.

  The hand function test used in rehabilitation cannot be performed unless there is an inspector with specialized knowledge. Therefore, a handicapped person who has a disability and lives at home cannot perform a finger function test when performing rehabilitation at home. Therefore, an automated hand test system that enables a disabled person who performs rehabilitation at home to compare the function of the hand of a healthy person of the same age as his / her age, so that the determination of the test result can be understood even without an inspector with specialized knowledge Will be needed.

  In order to show the effect of rehabilitation, several finger skill movement tests have been developed and used so far. Examples of hand-operated hand movement tests available in Japan include Simple Test for Evaluating Hand Function; STEF (Non-Patent Document 1), Finger Function Quotient Test; FQ Test (Non-Patent Documents 2 and 3), Manual Function Test; Patent Document 4), General Occupation Aptitude Test (Non-Patent Document 5), O'Connor Finger Dexterity Test (Non-Patent Document 6), and Purdue Peg Board Test (Non-Patent Documents 7 to 9).

  Among these hand and finger skill movement tests, STEF, FQ test, MFT, and general occupational aptitude tests are conducted to evaluate the overall upper limb function by performing multiple subtests. On the other hand, the O'Connor Finger Dexterity Test and the Purdue Peg Board Test are tests developed mainly as a vocational aptitude test for healthy persons, and the test is judged by an inspector having specialized knowledge.

  For example, Patent Documents 1 to 3 are disclosed as devices for inspecting the operation of fingers and the like.

  Conventional inspection has been performed by an inspector having specialized knowledge, and results have been determined. In addition, it is often difficult for people with disabilities to perform clinical trials, such as the operation performed in examinations is too detailed, the examination time is long, and the number of examinations is large. Therefore, there is a problem that it takes about 30 to 60 minutes to perform the inspection.

  The present invention has been made in view of the above problems, and can be carried out in a short time from a low ability to a high ability person, from a child to an elderly person, and a result determination is automatically displayed. To provide an inspection system.

  The present invention is a system for inspecting a finger's skillful movement ability of a subject, wherein nine pegs having different colors at both ends and the pegs are detachable, and each of the three pegs is vertically arranged in five rows 15 Using a board in which the holes are arranged at equal intervals in the vertical and horizontal directions, the pegs inserted in the three rows on one side of the board are moved to the opposite three rows one by one and / or removed one by one After that, measure the return operation time to insert upside down and compare the measured value input means to input the measured value, the measured value and the reference value obtained in advance for healthy subjects And an ability calculating means for calculating the ability.

  In addition, the system is a system for inspecting a subject's finger skillful movement ability, wherein the subject is 4 years old or older, and the measured value is an average value of two times of the same movement.

  Further, it is a method for inspecting the finger skillful movement ability of a subject constructed using a computer, wherein the measurement value input means provided in the computer includes nine pegs having different colors at both ends, and the pegs Using a board that can be attached and removed, with 3 holes vertically arranged in 5 rows and 15 holes arranged at equal intervals vertically and horizontally, pegs inserted into 3 rows on one side of the board, 3 rows on the opposite side one by one Measuring the time of the transfer operation to move to and / or the return operation to be inserted upside down after pulling out one by one, and inputting the measurement value, and then the ability calculation means provided in the computer, Comparing the measured value with a reference value obtained for a healthy person in advance, and calculating the skillful movement ability, is performed.

  Further, it is a method for inspecting the hand skillful movement ability of a subject, wherein nine pegs having different colors at both ends, and the pegs are detachable, and each of the three pegs is arranged in 15 rows in 5 rows. Using a board with holes arranged at equal intervals in the vertical and horizontal directions, the pegs inserted in the three rows on one side of the board are moved one by one to the opposite three rows, and / or removed one by one, Measuring the time of the return movement inserted upside down and obtaining the measurement value, and then comparing the measurement value with a reference value obtained in advance for a healthy person to calculate the skillful movement ability And a process.

  Further, there is provided a program for causing a computer to function as a means for inspecting a subject's finger skillful movement ability, wherein the computer includes nine pegs having different colors at both ends, and the pegs are detachable. Using a board with 15 holes in 3 rows vertically and 15 holes arranged at equal intervals vertically and horizontally, the pegs inserted in 3 rows on one side of the board are moved one by one to the opposite 3 rows After removing the operation and / or one by one, it measures the time of the return operation that is inserted upside down and functions as a measurement value input means for inputting the measurement value, and then the computer is connected to the measurement value. , Characterized in that it functions as an ability calculation means for calculating a skillful movement ability by comparing reference values obtained in advance for healthy subjects.

  In the present invention, a peg having an operable size is selected from the three types of pegs and inspected. In general, in the case of a central disease such as a stroke, the recovery of hand movement disorder is restored as much as possible from coarse movement to fine movement. The tool used for inspection is composed of three different types of pegs with a peg diameter of 3cm, 1.5cm, and 0.5cm. There are two types of `` return movement '', and it should be used for people with severe disabilities, patients in the early recovery stage of central diseases such as stroke, disabled persons with low skill movements such as infants and the elderly, and general healthy people Can do.

  In addition, there are three types of inspection methods: “Transfer”, which moves 9 pegs to different board holes, and “Return”, which inserts 9 pegs into the same hole on the board. It is possible to analyze healthy subjects using the results of each of the six subtests. In addition, examinations are conducted on persons with low physical and psychological endurance, such as severely disabled persons, patients in the early recovery stage of central diseases such as stroke, and disabled persons such as infants and the elderly who have low skillful movement ability. If the implementation limit time is set to 60 seconds in order to be the target, and “transfer operation” or “return operation” of 9 pegs cannot be performed within that time, analysis can be performed with the number of pegs that have been implemented. Therefore, the inspection time is very short.

  Also, according to the instructions displayed on the screen, enter the subtest time or number of pegs, age, dominant hand, subtest type, and input the measurement result, and the comparison with the skillful movement ability of normal age healthy persons will be made automatically. Displayed and requires no specialized knowledge for inspection.

  As described above, according to the finger skillful movement capability inspection system of the present invention, inspection is easy. Moreover, it is a simple test that can be performed regardless of age, such as being possible from infants to elderly people. In addition, six subtests with a degree of disability and relevance to daily life can be carried out in a maximum of 60 seconds. It is possible to evaluate and discriminate what percentage of the ability is compared to the ability related to the skillful movement.

It is a basic configuration of the present invention. It is a flowchart at the initial stage of inspection. It is a flowchart of the new measurement process in a test | inspection. It is a flowchart of an inspection data edit process. It is a flowchart of a test result display process. It is a related figure of the size of three types of pegs and daily life movement. It is a related figure of a difference in inspection operation and daily life operation. It is a block diagram of a finger skillful movement capability inspection system.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  Fig. 1 shows the basic configuration of a finger skillful movement test system. This finger skillful movement test system automatically analyzes and evaluates test results of patients with finger disabilities, and performs analysis to store and analyze finger skill movement test equipment 100 and its test result information. The apparatus 200 is comprised.

  With the hand-skilled movement tester 100 that inspects the finger function of the subject, the peg has a large peg with a diameter of 3 cm and a length of 8 cm, a peg with a diameter of 1.5 cm and a length of 5 cm. Three types of pegs with a diameter of 0.5 cm and a length of 3.5 cm are used. The boards into which these pegs are inserted have 3 vertical holes arranged at equal intervals in 5 horizontal rows, for a total of 15 holes. The board is 29 cm long x 31 cm wide when using a large peg, 17 cm long x 28 cm wide when using a medium peg, and 11 cm long x 18 cm wide when using a small peg, making it easy to carry around. It is a size. Note that the number of holes in the board can be used for inspection if the number is more than the above. Also, there is no particular problem if the board size increases in proportion to the number of holes. The examination should be completed by using 9 pegs, taking into account the physical and psychological durability of subjects with illnesses and disabilities, so that it can be easily understood by infants and the elderly. It is configured. Also, based on the relationship between the test results and daily activities, the “transfer operation”, which is highly related to the cooperative operation with the visual sense using fingers, such as carrying an object and picking an object, button operation and chopstick operation Because there are three types of pegs (large pegs, middle pegs, small pegs) for the two types of `` returning movements '' that are highly related to the operability of the thumb, index finger, middle finger, etc. In addition, inspections are performed with feasible subtests among the six subtests.

  The analysis device 200 that stores and analyzes the test results shows the procedure for performing the test on the subject on the screen, and the subject inputs the subject information, performs the test measurement, and inputs the result accordingly. Can be stored, analyzed, and evaluated, and the evaluation of the results can be shown to the subject on the screen.

[Examination of the reliability of hand skill movement test]
Examination of the reliability of the skillful movement test for fingers is 20 healthy infants (5.5 ± 0.5 years old) and 20 school-age children (10.5 ± 0.5 years old) who have no physical or cognitive problems and do not interfere with daily life The total size of pegs (100 young people: 20 (20.25 ± 0.43 years old), 20 middle-aged people (44.85 ± 2.73 years old), and 20 elderly people (65.35 ± 2.73 years old) 6 subtests of large, medium and small) and movement (transfer / return) were performed by a method of 12 movements by left and right hands.

  Table 1 shows average data of two measurements (seconds) obtained by two examiners targeting young people. Table 2 shows the measured data in terms of intra-class correlation coefficient: ICC (2.1) result, 95% confidence interval, and lower limit-upper limit. It is a high result of 0.75 or more in 9 operations.

  In addition, the results of measurements taken by young people by the same examiner after 4 months showed a high result of 0.75 or higher for all 12 actions measured by the intraclass correlation coefficient ICC (1.1).

  Table 3 shows the intra-class relations among subjects, 20 infants, 20 school-age children, 20 young children, 20 middle-aged people, and 20 middle-aged subjects, examined by the same examiner twice. This is a numerical ICC (1.1) result, 95% confidence interval, and lower limit-upper limit value. Of the 12 movements measured, the result was higher than 0.75, 4 infants, The result was 5 movements for young people, 10 movements for middle-aged persons, and 7 movements for middle-aged persons.

  In addition, regarding the reliability within the examiner after a certain period of time, the internal correlation coefficient ICC (1.1) showed a high result of 0.75 or more in all 12 measured actions. In addition, since the reliability is improved by using the average value of the twice measured values, the average value of the two trials is used in the finger skill movement test. As measurement data, the reliability of a single measurement is lower than using the average value measured twice. In the case of a young person or a handicapped person, it is not desirable because the burden on the subject will increase if the number of times is three or more.

[Examination of the validity of hand skill movement test]
Appropriateness of the hand-skilled movement test was conducted for 67 students who had no cognitive or physical problems (average age: 21.3 years, 15 males, 52 females, 65 right-handed, 2 left-handed) , STEF, O'Connor Finger Dexterity Test and Purdue Peg Board Test were conducted, and the validity of the finger skillful movement test was examined.

  As a result, the finger skillful movement test has a high standard-related validity with other test methods, and both show high test consistency.

  In addition, regarding the correlation between the right hand and the left hand, a significant correlation was obtained in all subtests. The high correlation between the right hand and the left hand means that the movement of this test is not a detailed movement that shows the superiority of the dominant hand, but a simple and basic movement that can be performed in the same way with either hand. This also indicates that this is a simple test that can be performed. Also, the inspection time is about 1 minute, which is very short compared to other inspections such as STEF.

[Creation of age-specific reference values for finger skill movement test]
Table 4 shows the subject attributes and the number of persons for creating the finger skillful movement ability test reference value. Standard values are created by performing 12 movements for each of the two hands for each of the 6 subtests of the hand skillful movement test for 982 people aged 3 to 88 years who have daily physical and cognitive problems. did.

  This test cannot be performed on 2-year-old children. It was also found that some tests were not possible for 3-year-old children, and any test was possible for 4-year-old children and older. Therefore, it is desirable that the age of examination is 4 years old or more.

  Table 5 shows the reference values (seconds) for each of the left and right hands and the age in the six subtests in the finger skillful movement test. In preparing the standard value, the National Laboratory Standards Council (NCCLS), shown in 1992, found that 95 out of 100 healthy people would be included, statistically speaking, the average value ± 2SD (standard deviation). In accordance with the guideline with the range (including 95.4% of all measurers) as the reference range, it is created based on the mean value ± 2SD derived from the survey results of 982 people.

  Based on this reference value, it can be applied to the following formula 1, and the skillful movement ability of the subject with respect to the skillful movement ability of healthy subjects of the same age can be expressed in%. Formula 1 is used when the subtest is completed within 60 seconds.

    [Formula 1] 100 x reference value (seconds) ÷ measured value (seconds)

  If it cannot be completed within the prescribed time of 60 seconds, the skill of finger skillful movement is determined using Table 6 based on the number of pegs that can be implemented in 60 seconds. Table 6 shows the subject's skillful movement ability with respect to the skillful movement ability of healthy subjects of the same age for each of the left and right hands and ages in the six subtests in%. Each value is calculated based on Equation 2 below.

    [Formula 2] 100 x reference value ÷ (540 ÷ [number of pegs implemented within 60 seconds])

  FIG. 2 is a flowchart showing an initial process of finger skillful movement ability inspection. Operate the inspection system and follow the instructions on the screen to select the subject first. If it is new, enter the subject name, gender, and date of birth. The new subject who inputs the existing subject and the subject information performs measurement using the finger skillful movement ability testing instrument 100 (processing 1). When editing the measured value data, the process proceeds to process 2. If the result is to be displayed, the process proceeds to process 3.

FIG. 3 is a flowchart showing a new measurement process in the finger skillful movement ability inspection system.
When performing a new measurement, it is divided into the case of following the instructions on the screen and the method of manual input independently.
When following the instructions on the screen, an operation is selected from four types of operations: right hand movement, right hand turn, left hand move, and left hand turn. Next, the peg type is selected from the three types of large, medium, and small pegs. The finger skillful movement performance test involves nine peg operations in 60 seconds. If it was possible within 60 seconds, enter the implemented time (in seconds). If 9 pegs could not be implemented in 60 seconds, enter the number of pegs that could be implemented. The age at the time of measurement is automatically calculated from the date of measurement and the date of birth of the subject entered in advance. On the other hand, if you are familiar with this inspection system and fully understand it, manual input can shorten the operation time. Enter the date of measurement, operation (one of right hand, right hand, left hand, left hand), peg selection (one of three types: large, medium, small) If 9 peg operations are performed in 60 seconds after the inspection is performed, the measurement time (seconds) is input. If 9 peg operations are not performed in 60 seconds, the number of operations that can be performed is input. In both cases of following the instructions on the screen and manually entering the original value, the reference value of the healthy person of the same age is assumed to be 100%, the% calculation of the measured value is performed, and the result is saved.

  FIG. 4 is a flowchart showing a data editing process in the finger skillful movement ability inspection system. The data editing process is used after the second measurement by the finger skillful movement ability inspection system. According to the screen of the hand skillful movement test system, recall the past data of the subject, enter the measurement date, select the movement (one of right hand, right hand, left hand, left hand), peg selection ( One of the three types of pegs: large, medium, and small), and when performing a 9-peg operation in 60 seconds after performing a skillful movement test for fingers, the measurement time (seconds) is 9 in 60 seconds. If the book peg operation could not be performed, enter the number of books that could be implemented. Using the reference value of healthy subjects of the same age as 100%, calculate the percentage of the measured value and save the result.

  FIG. 5 is a flowchart showing a result display process in the finger skillful movement capability inspection system. Based on the results stored in process 1 (new measurement process) or process 2 (data editing process), measurement results are extracted and selected, results are evaluated, and measurement results and evaluation results are displayed.

  FIG. 6 is a diagram showing the relationship between the sizes of the three types of pegs and the activities of daily living in the six subtests. Based on the relationship between the sizes of the three types of pegs shown here and the activities of daily life, the relationship between the size of the sub-test pegs in processing 3 and the daily life is shown on the screen.

  FIG. 7 is a diagram showing the relationship between the difference between the two types of peg motion and the daily life motion in the six subtests. Based on the relationship between the difference between the two types of peg motions shown here and the daily life motions, the difference between the peg motions of the subtest in process 3 and the daily life are shown on the screen. The two types of operations are a “transfer operation” in which the peg is moved from the first hole to a predetermined hole, and a “return operation” in which the peg is rotated 180 degrees into the first hole and inserted upside down. “Copying action” requires more visual hand coordination, and “returning action” requires more sophisticated fingertips. In addition, when measuring the right hand, the "moving operation" is a unit of 1 / 100th of a second, with 9 pegs arranged in the right 3 rows of the board and moving to the left 3 rows including the 3 in the center row Measure with When measuring the left hand, place nine pegs in the left three rows of the board and measure the time to move to the right three rows, including the three in the center row. In addition, when measuring twice, it carries out alternately with the left and right hands. On the other hand, the “returning operation” measures 9 pegs in 3 consecutive rows of the board and returns all pegs. Note that both ends of the peg are color-coded so that it can be determined whether or not the return has been performed. In addition, since this study is considered to have a learning effect due to multiple implementations, the examiner will demonstrate during the examination, but the subject will not practice.

  FIG. 8 is a block diagram of this system. In the finger skillful movement capability inspection system, the subject selection means 101 selects whether the inspection is performed for the first time or after the second time. In the first case, the subject information is input by the subject information input means 102. Both the new inspector and the second and subsequent inspectors use the new measurement data input means 103 to select the necessary inspections from the six subtests with the left and right hands and input the results. Correction of new and existing data is performed in the existing data editing means 104. The data that has passed through the new measurement data input means 103 and the existing data editing means 104 is compared with the ability of the normal person (ability calculation) by the calculation means 106, and the result is stored in the memory 107. Information from the calculation means 106 and the memory 107 is displayed on the screen in the result display means 105 for comparison with the ability of a healthy person of the same age and the relationship with the daily activities in the six subtests.
