Description

  The present invention relates to a rehabilitation system and method, and more particularly to a rehabilitation system and method for patients with higher brain dysfunction or dementia.

  Higher brain dysfunction is the appearance of symptoms such as memory impairment, attention disorder, and executive dysfunction due to brain damage caused by illnesses such as traffic accidents and strokes. Also, patients with dementia have the same symptoms as those with higher brain dysfunction.

  Rehabilitation (rehabilitation) for patients with higher brain dysfunction and dementia is performed in order to improve each of the above symptoms seen in patients with higher brain dysfunction and dementia. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2006-71897) discloses a dementia care support system that supports rehabilitation training for patients with dementia.

  Specifically, the invention according to Patent Document 1 uses a plurality of games corresponding to each symptom found in a patient with dementia. The invention according to Patent Document 1 has a measurement mode and a training mode. The patient operates the tablet terminal to select one of the measurement mode and the training mode.

  In the measurement mode, the patient's recognition level is measured by causing the patient to execute a game corresponding to various symptoms of dementia. When the measurement of the patient's recognition level is completed, the measurement result is displayed on the tablet terminal. On the other hand, the training mode is a mode in which a patient can freely select a game from a plurality of games.

  As described above, in the invention according to Patent Document 1, when the measurement mode is selected, the patient inevitably plays a game while being aware that his / her recognition level is being measured. As a result, since the patient cannot play the game as usual, the accuracy of the recognition level measurement is reduced. That is, in the invention according to Patent Document 1, it is difficult to confirm the progress of rehabilitation.

{4. Operation of Rehabilitation Support System 100}
{4.1. Execution of rehabilitation task program}
FIG. 4 is a sequence diagram showing the operation of the rehabilitation support system 100. With reference to FIG. 4, the operation of the rehabilitation support system 100 when the patient operates the tablet terminal 1 to execute a character search (rehabilitation task program 31) as a rehabilitation task will be described.

  As an initial condition, the management module 41 of the rehabilitation support program 40 has already started in the tablet terminal 1, and the server program 27 has already started in the server 2.

(Selecting rehabilitation tasks)
The rehabilitation support program 40 receives an input of the patient's name by operating the touch panel 13 by the patient (step S1). The rehabilitation support program 40 displays a list of rehabilitation tasks that can be performed by the patient after receiving the input of the patient's name. The rehabilitation support program 40 selects “character search” as the rehabilitation task based on the operation of the touch panel 13 by the patient (step S2).

  The rehabilitation support program 40 transmits the name of the patient accepted in step S1 and the task identification data to the server 2 (step S3). The task specifying data is data for specifying the rehabilitation task “character search” selected in step S2.

(Determination of questions according to level)
The server 2 receives the patient name and the task identification data transmitted in step S2. The server 2 refers to the patient management data 51 and acquires the patient ID corresponding to the received patient name (step S4). The ID is a number unique to each patient.

  The server 2 acquires the level of the patient for the rehabilitation task “character search” selected in step S2 from the level record data 52 based on the patient ID and the task identification data (step S5).

  FIG. 5 is a diagram illustrating an example of the level recording data 52. Referring to FIG. 5, the level recording data 52 records the patient ID and the patient level for each rehabilitation task in association with each other.

  In the rehabilitation support system 100, the tasks A to E are prepared as rehabilitation tasks, and the level of the rehabilitation task is 10 levels of 1 to 10. Here, the level of the rehabilitation task is a parameter that determines the content of the rehabilitation task, and the higher the level, the more difficult the rehabilitation task. That is, as the level of the rehabilitation task increases, it can be determined that the symptoms (attention disorder etc.) corresponding to the rehabilitation task are improved.

  In the level record data 52 shown in FIG. 5, the tasks A and B are rehabilitation tasks for attention disorder. Task C and task D are rehabilitation tasks for memory impairment. Task E is a rehabilitation task for executive dysfunction. The task A is “character search” and corresponds to the rehabilitation task program 31. The task E is a “pattern maze” and corresponds to the rehabilitation task program 32. Tasks B to D are rehabilitation tasks different from “character search” and “pattern maze”. Although the rehabilitation task program corresponding to the tasks B to D is not shown in FIG. 2, it is stored in the flash memory 14.

  Referring to FIG. 4, it is assumed that the ID of the patient identified in step S3 is “57841”. The task specifying data indicates “character search” as described above. In this case, the server 2 acquires “2” as the level of the task A corresponding to the ID “57841” in step S5.

  The server 2 determines the content of the rehabilitation task based on the level acquired in step S5 and the task management data 53 (step S6). The assignment management data 53 holds the contents of the assignments A to E shown in FIG. 5 in association with the levels. Based on the level acquired in step S5 and the rehabilitation task selected in step 2, the server 2 acquires the content of the rehabilitation task recorded in the task management data 53.

  In step S2, the task A “character search” is selected. For this reason, the question content of the task A includes the number of characters displayed in the designated character area described later and the number of characters displayed in the search area described later.

(Answer for rehabilitation task)
The server 2 transmits the question content data in which the question content determined in step S6 is recorded to the tablet terminal 1 (step S7). When the tablet terminal 1 receives the question content data, the rehabilitation support program 40 activates the rehabilitation task program 31 corresponding to the rehabilitation task “character search” selected in step S2 (step S8).

  The rehabilitation support program 40 notifies the activated rehabilitation task program 31 of the question content data received from the server 2 (step S9). The activated rehabilitation task program 31 displays an answer input screen for the rehabilitation task on the touch panel 13 based on the notified question content data (step S10).

  The rehabilitation task program 31 starts accepting input of answers to the rehabilitation task (step S11) and starts measuring the answer time (step S12). The patient executes the rehabilitation task by inputting an answer to the rehabilitation task displayed on the touch panel 13.

  When the input of the answer to the rehabilitation task is completed (step S13), the rehabilitation task program 31 ends the measurement of the answer time (step S14). The rehabilitation task program 31 acquires the time required from executing step S12 to executing step S14 as the answer time.

  FIG. 6 is a diagram showing an example of an answer screen for the task A “character search”. Referring to FIG. 6, in “character search”, a designated character area 61 and a search area 62 are displayed on touch panel 13.

  In the designated character area 61, a character (designated character) designated as a character to be searched for by the patient is displayed. In the example shown in FIG. 6, the designated characters are two characters “TSU” and “GA”. A plurality of characters are arranged in the search area 62. The number of designated characters and the number of characters arranged in the search area 62 are included in the question content data notified in step S9 (see FIG. 4) as described above. The designated character and the character in the search area 62 are determined at random.

  The rehabilitation task program 31 starts accepting an answer input when the answer input screen shown in FIG. 6 is displayed on the touch panel 13 (step S11 shown in FIG. 4), and starts measuring the answer time (see FIG. 4). Step S12). When the answer end button 63 on the answer input screen shown in FIG. 6 is tapped, the rehabilitation task program 31 ends the answer input acceptance (step S13 shown in FIG. 4) and ends the answer time measurement (FIG. 6). Step S14 shown in FIG.

  In “character search”, the patient searches for a designated character from characters arranged in the search area 62. That is, in the example shown in FIG. 6, the patient taps “T” and “GA” which are designated characters from among the characters arranged in the search area 62. The number of designated characters and the number of characters arranged in the search area 62 vary according to the patient's level regarding the task A “character search”. For example, as the level increases, the number of designated characters and the number of characters arranged in the search area 62 increase.

  With reference to FIG. 4, the rehabilitation task program 31 calculates the correct answer rate of the rehabilitation task displayed on the touch panel in step S10 after completing the measurement of the answer time (step S15). The method for calculating the correct answer rate is not particularly limited. The rehabilitation task program 31 notifies the rehabilitation support program 40 of the answer time of the rehabilitation task and the correct answer rate of the rehabilitation task (step S16).

  The rehabilitation support program 40 executes fatigue determination processing (step S17) when the rehabilitation task answer time and the rehabilitation task correct answer rate are notified. Details of the fatigue determination process (step S17) will be described later.

  Thereafter, when the patient repeatedly executes the same rehabilitation task, steps S10 to S17 are repeated. However, the type and arrangement of designated characters change randomly each time. On the other hand, when the patient executes another rehabilitation task, the patient operates the tablet terminal 1 to instruct the end of the rehabilitation task. The tablet terminal 1 selects a new rehabilitation task according to the patient's operation (step S2). Thereafter, the processing after step S2 is repeated.

  After the patient executes the same rehabilitation task a plurality of times (for example, 10 times), the rehabilitation support program 40 executes a level determination process (step S18).

(Level determination process (step S18))
FIG. 7 is a flowchart of the level determination process (step S18) executed by the tablet terminal 1. The level determination process (step S18) shown in FIG. 7 is executed by the level determination module 42 shown in FIG.

  The rehabilitation support program 40 activates the level determination module 42 when the rehabilitation task program 31 is activated (step S8 shown in FIG. 4). The activated level determination module 42 starts the process shown in FIG.

  With reference to FIG. 7, the level determination module 42 acquires the correct answer rate record data 56 of the patient who operates the tablet terminal 1 from the server 2 (step S21). Specifically, the level determination module 42 transmits the name of the patient input in step S1 (see FIG. 4) to the server 2, and requests the server 2 to transmit the correct answer rate recording data 56. When the server 2 receives the request from the level determination module 42, the server 2 transmits the correct answer rate record data 56 of the ID corresponding to the transmitted patient's name to the tablet terminal 1.

  FIG. 8 is a table showing an example of the correct answer rate recording data 56. The correct answer rate record data 56 is created for each patient, and records the average correct answer rate history for each of the tasks A to E. The average correct answer rate is an average of all correct answer rates when the same rehabilitation task is executed a plurality of times. The correct answer rate record data 56 shown in FIG. 8 records the history of the average correct answer rate of the patient whose ID is “57841”, and the average correct answer rate of the task A is recorded up to the 12th time. Other issues have not been recorded until the 12th time. This is because the frequency with which the patient executes the tasks A to E is different.

  Thereafter, the level determination module 42 stands by until the answer to the rehabilitation task ends (Yes in step S22). That is, the level determination module 42 stands by until it receives a notification of the answer time and average correct answer rate of the rehabilitation task being executed (step S16 shown in FIG. 4).

  The level determination module 42 acquires the correct answer rate of the executed rehabilitation task (step S23). Specifically, when the rehabilitation task program 31 notifies the rehabilitation support program 40 of the correct answer rate calculated in step S15 (see FIG. 4) (step S16), the level determination module 42 determines the correct answer of the executed rehabilitation task. Get rate.

  The level determination module 42 updates the correct answer rate record data 56 by calculating an average correct answer rate based on the correct answer rate obtained in step S23 and recording it in the correct answer rate record data 56 (step S24). For example, when the average correct answer rate of the task A “letter search” is acquired in step S23, the level determination module 42 indicates the acquired average correct answer rate of the task A in the 13th row of the correct answer rate record data 56 shown in FIG. In the “task A” field.

  The level determination module 42 determines the level for the rehabilitation task being performed by the patient based on the average correct answer rate calculated in step S24. Specifically, the level determination module 42 determines whether or not the average correct answer rate calculated in step S24 is 80% or more (step S26).

  When the average average correct answer rate is 80% or more (Yes in Step S26), the level determination module 42 determines to increase the level of the rehabilitation task answered by the patient (Step S27). The level determination module 42 transmits a level change notification including the determination content of step S27 to the server 2 (step S28), and proceeds to step S32. The server 2 updates the level record data 52 of the patient who operates the tablet terminal 1 based on the level change notification. For example, when the level determination module 42 determines that the level of the task A in the patient with ID “57841” is to be increased by 1, the server 2 uses the level record data 52 shown in FIG. 5 in the record with ID “57841”. The level of the task A is changed from “2” to “3”.

  On the other hand, when the average correct answer rate is smaller than 80% (No in step S26), the level determination module 42 determines whether the average correct answer rate is smaller than 30% (step S29).

  When the average average correct answer rate is smaller than 30% (Yes in Step S29), the level determination module 42 determines to lower the level of the rehabilitation task answered by the patient by one (Step S30). The level determination module 42 transmits a level change notification including the determination content of step S30 to the server 2 (step S28), and proceeds to step S32. The server 2 updates the level record data 52 of the patient who operates the tablet terminal 1 based on the level change notification. For example, when the level determination module 42 determines to lower the level of the task A by 1 in the patient with ID “57841”, the server 2 uses the level record data 52 shown in FIG. The level of A is changed from “2” to “1”.

  On the other hand, when the average correct answer rate is 30% or more (No in Step S29), the level determination module 42 determines to maintain the level of the rehabilitation task answered by the patient (Step S31), and proceeds to Step S32.

  In step S32, the level determination module 42 determines whether or not the patient has instructed the end of the rehabilitation task. When the patient instructs the end of the rehabilitation task (Yes in Step S32), the level determination module 42 transmits the correct answer rate record data 56 updated in Step S24 to the server 2 (Step S33). The server 2 updates the correct answer rate record data 56 stored in the HDD 25 based on the correct answer rate record data 56 transmitted from the tablet terminal 1.

  On the other hand, when the patient repeatedly executes the same rehabilitation task (No in step S32), the level determination module 42 determines whether or not the level of the patient who answered the rehabilitation task has been changed (step S34).

  When the patient level is maintained (No in step S34), the level determination module 42 returns to step S22 and waits until the answer of the newly executed rehabilitation task is completed.

  On the other hand, when the level of the patient is changed (Yes in step S34), the level determination module 42 acquires question content data corresponding to the changed level from the server 2 (step S35). Specifically, the level determination module 42 notifies the server 2 of the changed level and requests the server 2 to transmit the question content data. The server 2 determines the content of the rehabilitation task corresponding to the changed level and transmits it to the tablet terminal 1.

  The level determination module 42 notifies the rehabilitation task program 31 of the question content data acquired in step S35 (step S36). Thereby, the rehabilitation task program 31 can make a patient perform a rehabilitation task with the question content according to the changed level.

  Thus, the rehabilitation support system 100 does not use a special mode for measuring the level of various symptoms of higher brain dysfunction or dementia, and the rehabilitation task that is executed each time the patient executes the rehabilitation task. It is determined whether or not to update the level. Since the rehabilitation support system 100 can measure the patient's improvement level for various symptoms without making the patient aware that the level of various symptoms is being measured, it can be used for patients with higher brain dysfunction or dementia. The progress of rehabilitation can be confirmed with high accuracy.

(Fatigue determination process (step S17))
FIG. 9 is a flowchart of the fatigue determination process (step S <b> 17) executed by the tablet terminal 1. The fatigue determination process (step S17) is executed by the fatigue determination module 43 shown in FIG.

  The rehabilitation support program 40 activates the fatigue determination module 43 when the rehabilitation task program 31 is activated (step S8 shown in FIG. 4). The activated fatigue determination module 43 starts the process shown in FIG.

  The fatigue determination module 43 sets the fatigue detection counter to 0 at a predetermined timing (step S41). The fatigue detection counter indicates the number of times that the fatigue determination value has continuously exceeded a preset fatigue reference value. The fatigue judgment value is a numerical value indicating the degree of patient fatigue that occurs when the same rehabilitation task is repeatedly executed.

  The fatigue determination module 43 acquires answer time record data 54 of the patient who operates the tablet terminal 1 from the server 2 (step S42). Specifically, the fatigue determination module 43 requests the server 2 to transmit the answer time record data 54 by transmitting the name of the patient who operates the tablet terminal 1. When the server 2 receives the request from the fatigue determination module 43, the server 2 transmits the answer time record data 54 of the ID corresponding to the transmitted patient name to the tablet terminal 1.

  The timing at which steps S41 and S42 are executed is not particularly limited as long as the answer to the first rehabilitation task is completed. For example, the fatigue determination module 43 can execute steps S41 and S42 at the timing of starting the rehabilitation task program 31 in step S8 (see FIG. 4).

  FIG. 10 is a diagram showing a data structure of the answer time record data 54. Referring to FIG. 10, answer time record data 54 is created for each patient ID. FIG. 10 shows answer time record data 54 for the patient with ID “57841”. The answer time record data 54 includes assignment-specific record data 541 to 545. The assignment-specific recording data 541 to 545 correspond to the assignments A to E, respectively.

  FIG. 11 is a diagram showing an example of the task-specific recording data 541 shown in FIG. Referring to FIG. 11, task-specific record data 541 is data in a table format in which the answer time when the patient with ID “57841” answers task A is recorded for each level.

  In FIG. 11, the task-specific recording data 541 can record the answer times for the past six times for each level. The recording order X (X represents an integer of 1 to 6) indicates the order in which the answer times are recorded in the task-specific recording data 541. For example, in the level 1 column, the answer time recorded in the field corresponding to the recording order 1 is recorded earliest, and the answer time recorded in the field corresponding to the recording order 6 is recorded last.

  The past answer time recorded in the task-specific record data 541 is the answer time determined that the patient is not tired. Details of the recording of the answer time in the assignment-specific recording data 541 will be described later.

  Referring to FIG. 9 again, fatigue determination module 43 waits until the answer to the rehabilitation task is completed (Yes in step S43). That is, the fatigue determination module 43 stands by until it receives notification of the answer time and correct answer rate of the rehabilitation task being executed (step S16 shown in FIG. 4).

  The fatigue determination module 43 acquires the answer time of the executed rehabilitation task (step S44). For example, by notifying the rehabilitation support program 40 of the answer time measured by the rehabilitation task program 31 (step S16), the fatigue determination module 43 acquires the answer time for the task A “character search”.

  The fatigue determination module 43 calculates a fatigue determination value using the answer time acquired in step S44 and the answer time record data 54 acquired in step S41 (step S45). The fatigue determination value indicates the degree of fatigue at the present time of a patient who is operating the tablet terminal 1 to execute a rehabilitation task. Since the answer time acquired in step S44 is a parameter for calculating the fatigue determination value of the patient at the present time, in the following description, the answer time acquired in step S44 is described as “current answer time”.

For example, the fatigue determination module 43 calculates the fatigue determination value F according to the following equation (1).
F = | N _T −E _T | / σ _T (1)

In Equation (1), N _T is the current answer time, E _T is the average of past answer times recorded in the task-specific record data 541, and σ _T is recorded in the task-specific record data 541 This is the standard deviation calculated from the answering time.

  In FIG. 11, fields “541A” and “541B” in which no answer time is recorded exist in the “level 3” column in the task-specific recording data 541. The fact that the fields 541A and 541B are blank indicates that it is not long before the patient can perform the task A at level 3. Also, no answer time is recorded in the columns of “level 9” and “level 10”. This indicates that the patient level for task A has not reached level 9.

When the patient is performing the task A at level 3, the fatigue determination module 43, as described below, calculates the average E _T answer time at level 3 task A. That is, the fatigue determination module 43 provisionally inputs the predicted answer time assumed when the task A is executed at level 3 into the fields 541A and 541B, and then the six answers recorded in the level 3 column. calculating the arithmetic mean E _T time. The predicted answer time is recorded in the fatigue determination module 43 in advance. The predicted answer time is appropriately changed according to the content and level of the task.

  Referring to FIG. 9 again, fatigue determination module 43 determines whether or not the fatigue determination value calculated in step S45 is greater than or equal to a preset fatigue reference value (step S46).

  If the fatigue determination value is lower than the fatigue reference value (No in step S46), the fatigue determination module 43 determines that the patient is not fatigued and sets the fatigue detection counter to 0 (step S47). The fatigue determination module 43 records the current answer time used for calculation of the fatigue determination value in the task-specific recording data that is the acquisition destination of the answer time in step S44 (step S48).

  For example, when it is determined that the patient is not fatigued while performing the task A of level 1, the fatigue determination module 43 records the current answer time in the task-specific recording data 541. Specifically, the fatigue determination module 43 deletes the answer time of the recording order 1 at level 1. The fatigue determination module 43 moves the answer times of the level 1 recording orders 2 to 5 to the recording orders 1 to 5 and then records the current answer time in the level 1 recording order 6.

  Referring to FIG. 9, when the fatigue determination value is equal to or greater than the fatigue reference value (Yes in step S46), fatigue determination module 43 determines that the patient may be fatigued by executing the rehabilitation task. Then, the fatigue detection counter is incremented (step S51). The fatigue determination module 43 determines whether or not the fatigue detection counter is greater than or equal to a preset detection reference value (step S52).

  If the fatigue detection counter is lower than the detection reference value (No in step S52), the fatigue determination module 43 determines that the patient is not fatigued and proceeds to step S49. On the other hand, when the fatigue detection counter is equal to or greater than the detection reference value (Yes in step S52), the fatigue determination module 43 determines that the patient is fatigued due to the execution of the rehabilitation task. The fatigue determination module 43 displays a message prompting for a break on the touch panel 13 (step S53), and proceeds to step S49.

  The fatigue determination module 43 determines whether or not the patient has instructed the end of the rehabilitation task in step S49 (step S49).

  When the patient instructs the end of the rehabilitation task (Yes in step S49), the fatigue determination module 43 transmits the answer time record data 54 to the server 2. The server 2 specifies the answer time record data 54 of the patient who operates the tablet terminal 1 from the answer time record data 54 recorded in the HDD 25, and transmits the specified answer time record data 54 by the fatigue determination module 43. It replaces with the answer time record data 54 which was made.

  On the other hand, if the patient has not instructed the end of the rehabilitation task (No in step S49), the fatigue determination module 43 returns to step S43 and waits until the answer to the rehabilitation task is completed.

  Thus, the rehabilitation support system 100 calculates a fatigue determination value indicating the degree of fatigue of the patient every time the patient performs a rehabilitation task, and determines whether or not the patient is fatigued based on the fatigue determination value. . When the rehabilitation support system 100 determines that the patient is tired, the rehabilitation support system 100 displays a message prompting the patient to take a break on the tablet terminal 1. As a result, since it is possible to prevent the rehabilitation task from being repeatedly executed without noticing that the patient is tired, it is possible to prevent a decrease in the correct answer rate of the rehabilitation task due to the patient's fatigue. As a result, it is possible to prevent the level of the rehabilitation task from decreasing due to patient fatigue, and to accurately grasp the progress of the patient's rehabilitation training.

{About Exercise E “Pattern Maze”}
Hereinafter, the task E “pattern maze” will be described as an example of the rehabilitation task. FIG. 12 is a diagram illustrating an answer input screen for the task E “pattern maze” displayed on the display 13 of the tablet terminal 1. FIG. 13 is a diagram showing a correct answer display screen of “pattern maze” shown in FIG.

  Referring to FIG. 4, when the patient selects task E in step S2, rehabilitation support program 40 starts rehabilitation task program 32 corresponding to task E “pattern maze” (step S8). The rehabilitation task program 32 executes steps S10 to S15 in place of the rehabilitation task program 31. At this time, the answer input screen shown in FIG. 12 is displayed on the display 13 in step S10.

  Referring to FIG. 12, three types of graphic patterns are displayed in the answer column 72. The order column 71 describes the order in which the graphic patterns displayed in the answer column 72 are traced. The patient follows the order described in the order field 71 and follows the graphic pattern displayed in the answer field 72 from the start to the goal while touching the touch panel 13. Although not shown in FIG. 12, the rehabilitation task program 32 causes the touch panel 13 to display a route followed by the patient. After the patient traces the graphic pattern from the start to the goal, the patient performs answer matching by tapping the answer matching button 73. When the answer matching button 73 is tapped, the rehabilitation task program 32 displays the correct answer display screen shown in FIG.

  The rehabilitation task program 32 starts measuring the answer time from the time when the patient first touches the touch panel 13 after displaying the answer input screen shown in FIG. 12 (step S12 (see FIG. 4)). And the rehabilitation task program 32 should just complete | finish measurement of answer time at the time when the answer matching button 73 was touched (step S14 (refer FIG. 4)).

{Modification}
Further, when the correct answer rate lower than 30% continues for a certain number of times, the rehabilitation learning support system 100 may shift to the error-free learning mode and cause the patient to execute the rehabilitation task.

  The error-free learning mode is a mode in which the correct answer of the rehabilitation task is displayed before the patient inputs the answer of the rehabilitation task. By causing the patient to execute the rehabilitation task in the error-free learning mode, the correct answer rate of the patient can be improved, and there is an advantage that the willingness to tackle rehabilitation can be improved.

  FIG. 14 is a flowchart showing the operation of the error-free control module 44. FIG. 15 is a diagram illustrating an example of screen transition of the touch panel 13 when the mode is shifted to the error-free learning mode during the execution of the task A “character search”.

  The error-free control module 44 starts the process shown in FIG. 14 when the correct answer rate is calculated in step S15 shown in FIG. The error-free control module 44 determines whether the correct answer rate lower than 30% is continued m times (step S101). Here, m is a natural number of 2 or more.

  When the correct answer rate lower than 30% has not continued m times (No in step S101), the error-free control module 44 ends the processing shown in FIG. 14 and notifies the rehabilitation support program 40 of the answer time and the correct answer rate. (Step S16 shown in FIG. 4).

  On the other hand, when the correct answer rate lower than 30% continues m times (Yes in step S101), the error-free control module 44 determines to shift to the error-free learning mode (step S102). As shown in FIG. 15, the error-free control module 44 displays an explanation screen 61 that explains to the patient that the mode will shift to the error-free learning mode (step S103).

  Next, the error-free control module 44 displays the answer display screen 62 on the touch panel 13 (step S104). The answer display screen 62 displays the question content of the task A “Looking for characters” and the answer to the question content. The answer display screen 62 shown in FIG. 15 surrounds the answer of the rehabilitation task “letter for text” in a search area 62 with a square frame.

The rehabilitation task program 31 causes the patient to execute the rehabilitation task by displaying an answer input screen (step S105). Specifically, as shown in FIG. 15, the rehabilitation task program 31 causes the display on the touch panel 13 to transition from the answer display screen 62 to the answer input screen 63, and causes the patient to input the answer to the rehabilitation task “character search”. The rehabilitation task program 31 calculates the correct answer rate when the input of the answer is completed (step S106).
The error-free control module 44 determines whether or not the correct answer rate calculated during the execution of the error-free learning mode is 30% or more consecutively p times (step S108). p is a natural number of 2 or more

  If the correct answer rate is 30% or more consecutively p times (Yes in step S108), the error-free control module 44 displays an error-free learning mode end message on the touch panel 13 (step S109), as shown in FIG. The process ends. The error-free control module 44 returns to step S10 shown in FIG. 4 and causes the patient to execute the rehabilitation task “character search” in the normal mode that is not the error-free learning mode.

  On the other hand, when the correct answer rate of 30% or more has not continued p times (No in step S108), the error-free control module 44 determines whether or not the correct answer rate lower than 30% has reached q times cumulatively. (Step S110). q is a natural number of 2 or more.

  If the correct answer rate lower than 30% has reached q times cumulatively (Yes in step S110), the rehabilitation task program 31 determines to lower the patient's level for task A “character search” by one (step S111).

  The error-free control module 44 notifies the server 2 that the level is lowered by 1, and obtains question content data corresponding to the new level (step S112). The error-free control module 44 returns to step S104 and displays an answer display screen corresponding to the newly obtained question content data on the touch panel 13.

  On the other hand, when the correct answer rate lower than 30% has not reached q times cumulatively (No in Step S110), the error-free control module 44 returns to Step S104. That is, the error-free control module 44 displays a new answer display screen on the touch panel 13 while maintaining the level of the task A “character search”.

{Other variations}
In the above embodiment, as shown in FIG. 5, the tasks A and B are rehabilitation tasks for attention disorder, the tasks C and D are rehabilitation tasks for memory impairment, and the task E is a rehabilitation task for performance dysfunction. Although an example was demonstrated, it is not limited to this. The number of rehabilitation tasks may be one or two or more.

  In the said embodiment, although the tablet terminal 1 demonstrated the example which performs a fatigue determination process (step S17), it is not limited to this. The tablet terminal 1 may not perform the fatigue determination process (step S17). Even in this case, since the tablet terminal 1 performs the rehabilitation task without being aware that the determination of its own level is being performed, the progress of the patient's rehabilitation is accurately grasped. can do.

  In the above embodiment, an example is described in which, in the fatigue determination process (step S17), when the fatigue detection counter is equal to or greater than a preset detection reference value (Yes in step S52), it is determined that the patient is fatigued. However, it is not limited to this. The fatigue determination module 43 may not use a fatigue detection counter. For example, the fatigue determination module 43 may determine that the patient is fatigued when the fatigue determination value is greater than the fatigue reference value. That is, as long as the fatigue determination module 43 can determine whether the patient is fatigued based on the fatigue determination value, the determination criterion for determining whether the patient is fatigued is not particularly limited.

  In the said embodiment, although the tablet terminal 1 and the server 2 are performing the information processing mentioned above, only the tablet terminal 1 may perform all the information processing mentioned above.

  While the embodiments of the present invention have been described above, the above-described embodiments are merely examples for carrying out the present invention. Therefore, the present invention is not limited to the above-described embodiment, and can be implemented by appropriately modifying the above-described embodiment without departing from the spirit thereof.
