Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a device for assessing and training the degree of hemilateral spatial agnosia in the fields of neuropsychology and rehabilitation medicine.

[0002]

2. Description of the Related Art The pathophysiology of hemilateral spatial agnosia that is evaluated and trained using the present invention will be described. By cerebrovascular disorder,
When a cortical lesion that integrates sensory inputs occurs, a unique cognitive impairment corresponding to this damaged cortex occurs. When the right hemisphere of the brain is damaged, left hemisphere-related disorders such as dysfunction of the left hemisphere of the body and cognitive impairment of ignoring the left hemisphere of the outer space often occur. When the left hemisphere of the brain is damaged, disorders related to the left and right sides of the body and the outer space often occur, such as disorders of left and right discrimination. The left hemisphere of the brain has the function of paying attention to the right side of the visual space, while the right hemisphere of the brain has the function of paying attention to the entire visual space. Therefore, when the right hemisphere of the brain is damaged, the perception of the left side of the visual space is lost.
It is said that when the left hemisphere is damaged, the cognition of the right side of the visual space is temporarily lost, but it gradually recovers.

When only the right hemisphere of the brain is damaged, the function of the left hemisphere is normal and the right visual space can be recognized, but the left half of the visual space is ignored because the cognitive ability of the left visual space is lost. Therefore, when such a medical condition is exhibited, treatment and training for attracting attention to the left space are required. When only the left hemisphere of the brain is damaged, the function of the right hemisphere is normal and the left and right visual spaces can be recognized. Even if the right half of the visual space is agnosed due to this damage, the damage disappears over time, and in some cases it gradually becomes general and recovers. As mentioned above, in the case of damage to the right hemisphere of the brain, it is necessary and important to treat it so as to restore the function of attention and alertness to the visual space of the left half.

As a treatment method for visual space agnosia, (1) the left side of the patient K is stimulated so that the attention of the patient K can easily reach the left side. (2) The patient K is caused to perform an action for enhancing the left side viewing. (3) The patient K gives an appropriate instruction so that he / she may be aware of his / her own disorder, and facilitates compensatory behavior. (4) If you cannot live a normal life due to visual space agnosia, have the students practice the life automatically and correctly.

In the conventional evaluation, a line segment bisection test,
Various things such as picture copying and erasure test are used and not standardized. Therefore, the evaluation results have not been quantified yet. The practitioner subjectively interpreted the data. The line segment bisection test is a method of presenting a string of a predetermined length horizontally at a distance of 30 cm in front of the patient K,
Ask the person to estimate the midpoint. It is examined how many centimeters the point designated by the patient K deviates from the normal midpoint, and the degree of pathological condition of visual spatial agnosia is evaluated from the result. In the examination by copying the picture, put the picture on the front desk of patient K,
This picture is copied on another paper, and it is checked whether the pattern of the picture can be written correctly and whether the position is correct, and the degree of symptoms of visual spatial agnosia is evaluated from the result. In the inspection by the erasing test, a sheet on which the numbers are randomly printed is placed on the front desk of the patient K and the patient K erases the determined number. At the time of this work, oversights, mistakes, work required time, search route, etc. are known, and the degree of symptoms of visual space agnosia is evaluated from the results.

[0006]

With the methods such as the line segment bisector inspection method, the picture copying, and the erasing test described as the prior art, the evaluation standard is ambiguous and quantification is difficult. It was a thing. Further, in the prior art, even though there is a device that evaluates the degree of hemilateral spatial agnosia, there is no device that performs training to recover the symptoms of hemilateral spatial agnosia.

Next, the protocol will be described. There are an evaluation protocol and a training protocol in the protocol. The evaluation protocol is an evaluation pattern group created to evaluate the symptoms of the patient K. The evaluation pattern is also used when evaluating the training result. The training protocol is a training pattern group created for training in order to recover the symptoms of the patient K. The training pattern group is a combination of various training patterns such as a training pattern for searching the patient K in the horizontal direction and a training pattern for searching in the vertical direction. The protocol negotiates evaluation and training, and rationalizes evaluation and training. The optotype controller 27 executes an operation based on these two types of protocols.

Next, the creation of the evaluation pattern will be described. ROM for reading and creating evaluation patterns
It is created by reading from the evaluation pattern registered in 30. When the evaluation pattern is manually created, the optotype selection switch 17 is manually operated to turn on each of the optotypes 3 manually to form the evaluation pattern on the surface of the training board 4. One or a plurality of randomly selected optotypes 3 randomly selected from the 49 optotypes 3 on the four surfaces of the training board are simultaneously turned on, and the evaluation pattern is displayed. When it is desired to display an unspecified evaluation pattern other than the evaluation pattern registered in the ROM 30 on the training board 4, it is manually created.

Next, the creation of training patterns will be described. When creating the training pattern automatically, based on the evaluation result, or by the function of the optotype controller 27,
A training pattern is formed on the surface of the training board 4 more reasonably and automatically based on the previous training result data.
ROM30 to read and create training patterns
Created by reading from the training patterns registered in.
A number is assigned to each of the training patterns, and these numbers are ascending numbers sequentially assigned from a training pattern that is easy to find to a training pattern that is hard to find gradually, that is, a training pattern from easy training to difficult training. When the training is carried out after the evaluation is carried out, the optimum training pattern is automatically selected by the controller 5 on the basis of the evaluation data and appears on the surface of the training board 4. When the training pattern is created manually, it is similar to the case where the evaluation pattern is created manually.
7 is manually operated, and each optotype 3 is manually turned on to form a training pattern on the surface of the training board 4.

Next, items to be evaluated using the evaluation protocol will be described. First, regarding the “visual space”, the region where the optotype switch 2 pushed by the patient K is present is the visual space.
The neglected space determines whether it is the right space or the left space,
The evaluation pattern to be displayed next is automatically changed to the right evaluation pattern or the left evaluation pattern. Secondly, "search habits"
With regard to, the search habit is inferred based on the path of the patient K pressing the optotype switch 2. Thirdly, regarding the “search time”, the work time from when the patient K starts to press the optotype switch 2 to when the operation of turning off the optotype 3 is completed, and when one of the optotype switches 2 is pressed, Target switch 2
There are two times to press, and these times are measured. Fourth, the "total time" is the time from the start of evaluation until each target switch 2 is pressed. For example, it takes from the start time when the start switch 18 is pressed until the first target switch 2 is pressed. The time taken from the start time to the second push of the optotype switch 2, such as the time taken from the start time to the push of the optotype switch 2 in sequence. To measure. Using the evaluation protocol, the four items of visual space, search habit, search time, and cumulative time are evaluated, and a training protocol is created based on these evaluation results.

Next, the work of the patient K performed on the apparatus of the present invention will be described. An evaluation pattern is displayed on the training board 4 for evaluation, and a training pattern is displayed for training. In the embodiment, 16 patterns are registered in the ROM 30 as evaluation patterns and 147 patterns are registered as training patterns. 147
The individual training patterns are roughly divided into four steps from the first step to the fourth step. 8 to 6 for each step
There are 0 training patterns. First, the evaluation pattern is
An evaluation pattern is created on the training board 4, starting with a basic evaluation pattern and then changing to the next evaluation pattern based on this evaluation result. A large number of evaluation patterns are prepared so that the patient K can be evaluated from various angles. The training pattern is effectively created to bring patient K back to a healthy state. When it is possible to reliably achieve one training pattern, move to another training pattern higher than the training pattern and proceed with the training.
As the training progresses, it becomes difficult to find the luminescent target 3 gradually,
The training pattern is set to perform difficult training. If the training pattern cannot be achieved, repeat the training using a training pattern lower or equal to the training pattern.

Next, a description will be given of the work of the robot for evaluating the hemilateral spatial agnosia. The evaluation pattern is displayed on the four surfaces of the training board for the purpose of working on the side of the hemilateral spatial agnosia evaluation. The patient K faces the training board 4 on which the evaluation pattern is presented according to the instruction of the user T, and among the total optotypes 3 on the upper surface of the training board 4,
Look for the lit target 3 and turn it off as soon as it is found. The patient K searches for the lit target 3 among all the targets 3 on the upper surface of the training board 4, and sequentially erases them as soon as they are found.
The optotype controller 27 turns on the patient K from the "start" when the patient K starts turning off the light by turning on the start switch 18.
Counts the time until the stop switch is turned on and "stopped" when the intention is displayed that the work has been completed. The optotype controller 27 calculates data relating to the route in which the patient K operated the optotype switch 2, the consumption time, the position of the unerased optotype, and the like, and creates evaluation data.

When there is a symptom of acupuncture of the right hemilateral space or a sense of left hemilateral space, the lighting target 3 on the right side from the center of the training board 4 or the left side of the training board 4 from the center. The lit target 3 located in can not be found and cannot be turned off. Therefore, the index switch 2 to be pushed is not pushed and the corresponding index 3 remains lit. When the special situation as described above appears, the optotype controller 27 displays the symptom of whether the patient K is right hemilateral spatial agnosia, ie, right side neglected, or left hemilateral spatial agnosia, ie left neglected. Whether to have it is automatically determined.

When the special situation as described above appears, the optotype controller 27 collates the results of the lighting control of the evaluation pattern and the extinguishing work, and then evaluates the above-mentioned four items. The evaluation is printed on the printer 39, used for diagnosis, and recorded on the memory card 33. The marking paper is attached to each optotype 3 and the patient K
The route touched by is specified. As a specific example of the evaluation, evaluation of whether the left half side is ignored or the right half side is ignored, the degree of the half side ignored, that is, the degree of disease, the position and range of the ignored region, and 16 evaluation patterns are sequentially executed. Then, the ranking evaluation is performed according to the number of evaluation patterns. From these assessments, it is possible to quantify the extent to which the symptoms of hemilateral spatial agnosia are mild or severe.

Next, the work for the training to recover the hemilateral visual space agnosia will be described. As in the case of the hemilateral visual space agnostic evaluation work, the patient K faces the training board 4 on which the specific training pattern is presented by the instruction of the optotype controller 27, A training is conducted in which the lit target 3 is searched for among all the targets 3 on the upper surface of the training board 4, and the targets 3 are sequentially erased as soon as they are found. When repeating training, as described above, the training pattern is automatically changed according to the symptoms. In the case of manual training, the training pattern is changed to a difficult one, and the training is advanced. The optotype controller 27 displays a training pattern, which is more effective in the recovery of the symptom, on the upper surface of the training board 4. The accuracy of the target switch 2 when the light is turned off, the value of the search time, etc. Among the training patterns that have achieved the criteria set in the evaluation items described above, the training pattern number of the highest order, that is, the training pattern of the most difficult training Use as a measure of K.

An example of the evaluation pattern is shown in FIG. 5, and an example of the training pattern is shown in FIG. In FIGS. 5 and 6, the black circles mean the turned-on target 3, and the white circles mean the turned-off target 3. 6 is used as a training pattern based on the result using the pattern shown in FIG. 5 as the evaluation pattern.
In the case of using the pattern shown in, an example of using the pattern from evaluation to training is explained. As a result of having the patient K turn off the light using the evaluation pattern shown in FIG.
Disappear from the top of the rightmost column to the bottom,
Subsequently, the right second column is erased from the top to the bottom in order, and the right third column and the optotypes 3 on the left of the right third column
If the patient could not be erased at all, it can be seen that this patient K has a habit of first paying attention from the upper right and then ignoring the left side. Using the training pattern shown in FIG. 6, the patient K is first trained so that the right shoulder of the training pattern serves as a base point and attention is directed to the left side from that point.

Next, a mode of recovery training for hemilateral spatial agnosia performed using the pursuit target 8 will be described. The controller 28 for the motor is operated to move the tracking target 8. The moving direction and speed of the follow-up visual target 8 are determined in correspondence with the symptom of hemilateral visual agnosia. The patient K visually follows the moving visual target 8. By this training, the patient K is made aware of the hemilateral spatial agnosia, is trained to pay attention to the agnostic region, and prompts recovery.

Next, a mode of evaluation / training using a numerical sheet will be described. The evaluation / training pattern is displayed on the training board 4 on which the number sheets are hung, and the patient K is
The numbers attached to the optotypes 3 that are turned on are read out aloud one after another and evaluated and trained. The user T records the number read out by the patient K and evaluates it based on the record. The visual path can be understood from the order in which the patient K reads it.

Next, a flow chart of the controller 5 in the evaluation mode shown in FIG. 8 will be described. The user T starts the controller 5 to start the evaluation. The controller 5 causes all 16 evaluation patterns 1 to 16 which are preliminarily arranged on the training board 4 to appear in sequence one by one. The patient K turns off the light toward the training board 4 for evaluation. The controller 5
After the above turning-off work, calculation is performed based on the above-described four evaluation items to obtain an evaluation result. The controller 5 determines whether the evaluation pattern on the surface of the training board 4 is the final evaluation pattern, that is, the evaluation pattern of number 16. If the evaluation pattern is not the final evaluation pattern, the evaluation pattern with the next number is displayed, and if it is the final evaluation pattern, the evaluation is terminated. The treatment person T displays the evaluation result in the memory card 33.
Register in.

Next, a flow chart of the controller 5 in the training mode shown in FIG. 9 will be described. The user T starts the controller 5 and starts the training. Based on the above-mentioned evaluation result, the controller 5 has a training pattern devised so that the number of the targets 3 turned off, the position of the targets 3 turned off, the order in which the targets 3 are turned off, etc. become normal by the training. Create automatically. This training pattern is made up of a plurality of different training patterns into one set. The training board 4 is provided with a set of automatically created training patterns described above.
One by one, all appear one after another from easy to difficult. In other words, as the training progresses, the turning-off work gradually progresses into a training pattern in which it gradually becomes difficult. The patient K turns off the light toward the training board 4 for training. The controller 5 performs a calculation based on the above-described four evaluation items after the turning-off work to obtain a training result. The controller 5 determines whether the training result has reached a predetermined value. That is, when the controller 5 judges from the training result that the training is insufficient, the controller 5 repeatedly uses the same training pattern and provides the light-off work. On the contrary, when it is determined that the training is sufficient, the process proceeds to the next step, and it is determined whether the training pattern is the last training pattern. As a result, in the case of a negative determination, the advanced training pattern is displayed on the surface of the training board 4, the training pattern is subjected to the light-off work, and in the case of the last training pattern, the training is finished. More specifically, when the training pattern on the surface of the training board 4 is not the last training pattern, the training patterns are sequentially advanced one by one and the training is repeated. When the training according to the training pattern of is achieved and the training is achieved, the training ends. It is considered that the condition of hemilateral spatial agnosia has recovered after the training. When the operation of the device is stopped during the training before the end of the training, the device is registered in the memory card 33 and the training is continued after the current operation is stopped in the next training.

Also, the output of the controller
Since it can be displayed or printed out or recorded on a data card, it is possible to compare the implementation status of the training in time series, which is more advantageous in diagnosing the degree of recovery. In addition, the route related to the turning-off work of each optotype can be known from the printed paper or from the read number, and the pathological condition of the patient in the visual search route can be evaluated. From this evaluation, the patient's pathological condition can be notified to the patient, and the patient can be made aware of the condition, and training for recovery can be performed. Patients with upper limb motor function impairments can be trained without using the upper limbs by performing evaluation and training by using the number sheet to indicate the position of the target by reading the numbers. However, there is an advantage that the present invention can be used.

Further, since the tracking target that moves and stops on the surface of the training board is added, the tracking target that moves between both ends of the training board is tracked over the entire area. , It is possible to call attention to the area of hemi-visual space agnosia, and to effectively recover the condition.

Further, the training board is supported by a tilting mechanism provided on the back surface of the training board and an elevating and lowering supporting portion for supporting the tilting mechanism so as to be vertically movable. According to the above configuration, the training board can be moved up and down and fixed, and further, the training board can be upright or tilted at an appropriate angle, so that the training board is suitable for the patient's condition and individual differences. It can be set and is convenient for patients using the device of the present invention, and can be set and provided in a state suitable for all patients. Also, when the surface of the training board is an upright surface, evaluation and training can be performed in a planar view, and when it is an inclined surface, three-dimensional evaluation and training considering depth can be performed. There is also an effect of increasing the range of training modes.
