Description

[Technical field]

[0001] The present disclosure relates to a motor function measurement device, a motor function measurement program, and a motor function measurement system that utilize a distance measuring sensor. [Background technology]

[0002] In recent years, it has become known that as people age, their physical and mental vitality, such as their motor functions, declines, which can impair their daily living functions and lead to a state of frailty in which physical and mental fragility appears, such as a tendency to stay indoors. Therefore, it is desirable to have high motor functions in order to maintain good health.

[0003] In addition, if frailty is detected and treated early, it is possible to improve to a state close to healthy and reduce the possibility of reaching a state requiring nursing care. Therefore, it is important to regularly measure and evaluate motor function, understand your current condition, and notice any changes in motor function early.

[0004] Patent Document 1 discloses a measurement method in which a distance sensor, such as an infrared sensor or a laser sensor, is attached to a support so as to be positioned above the user's head, and this distance sensor is used to evaluate the user's balance and lower limb muscle strength.

[0005] [Patent Document 1] JP 2020-044295 A Summary of the Invention [Problem to be solved by the invention]

[0006] Measuring motor function requires time and effort, such as preparing measuring devices and people to measure, so continuous measurement can be difficult. More specifically, there are methods for measuring motor function, such as preparing measuring devices such as sensors and cameras each time a measurement is taken, and methods such as the TUG test, in which a person to measure is prepared and measures the subject, but these methods require a lot of time and effort, making continuous measurement difficult.

[0007] Furthermore, if motor function is not measured regularly, there is a risk that a decline in one's motor function may go unnoticed and result in injury or accident, such as a fall.

[0008] Furthermore, in recent years, nursing care facilities have been helping care recipients live independently. Therefore, care recipients are encouraged to do as much as they can by themselves in their daily lives, but sometimes falls occur without noticing a decline in motor function.

[0009] For these reasons, there has been a demand to install a measuring device in a location that the user uses every day and be able to measure motor function in response to daily movements such as sitting down and getting up from a seat, without the user being aware that they are being measured. [Means for solving the problem]

[0010] The motor function measuring device according to the present disclosure comprises a sensor unit having a sensor that performs at least one of measurements from the start to the completion of a user's sitting down movement and from the start to the completion of a user's leaving movement and obtains data of the measurements, an evaluation unit that evaluates the user's motor function from the data obtained by the sensor unit, and an alarm unit that issues an alarm when the evaluation unit evaluates that the user's motor function has deteriorated.

[0011] The motor function measurement program according to the present disclosure includes a step of performing at least one of measurements from the start to the completion of a user's sitting motion and from the start to the completion of a user's leaving motion to obtain data of the measurement, and a step of evaluating the user's motor function from the obtained data. and a step of issuing a notification when the evaluation indicates that the user's motor function has deteriorated.

[0012] In addition, the motor function measurement system of the present disclosure includes a sensor unit having a sensor that performs at least one of measurements from the start to the completion of a user's sitting down movement and from the start to the completion of an unseating movement and acquires data of the measurements, an evaluation unit that evaluates the user's motor function from the data acquired by the sensor unit, and an alarm unit that issues an alarm when the evaluation unit evaluates that the user's motor function has deteriorated. Effect of the Invention

[0013] According to the present disclosure, motor function can be measured without the user being aware of the measurement. [Brief description of the drawings]

[0015] First embodiment An example of the configuration of the motor function measuring device 1 will be described below with reference to Fig. 1. As shown in Fig. 1, the motor function measuring device 1 includes a sensor unit 11 that measures the start to completion of a user's sitting motion and the start to completion of an exit motion, an evaluation unit 12 that evaluates the user's motor function from data acquired by the sensor unit 11, and a notification unit 13 that issues a warning when the evaluation unit 12 evaluates that the user's motor function has deteriorated. The motor function measuring device 1 is installed in a toilet.

[0016] The sensor unit 11 will be described as using a distance measuring sensor that measures the distance from the sensor position to the user's position. Therefore, in the following, the information acquired by the sensor unit 11 is distance measurement data. The sensor unit 11 can measure at least one of the start to completion of the user's sitting down action and the start to completion of the user's leaving action.

[0017] Typically, the evaluation unit 12 performs exercise evaluation based on distance measurement data acquired by the sensor unit 11 periodically and continuously.

[0018] The notification unit 13 may be any unit that issues a warning to the user or the person taking the measurement. Therefore, the notification method by the notification unit 13 may be a sound notification (alert) from a mobile terminal such as a smartphone held by the user or the person taking the measurement, as described below, but may be changed as appropriate.

[0019] Embodiment 2 Next, we will explain an example of the configuration of a motor function measurement system 2 that uses a cloud service (hereinafter referred to as the cloud) that allows access to IT resources such as servers and storage, and application software over a network.

[0020] 2 is a diagram showing an example of the overall configuration of the motor function measurement system 2 and the relationship between the constituent items for transmitting and receiving measurement information, control information, etc. The motor function measurement system 2 includes a sensor unit 21 that measures the motor ability of a user in the toilet, an evaluation unit 22 that evaluates the motor function of the user from data acquired by the sensor unit 21 in the cloud, and a notification unit 23 that issues a warning.

[0021] Two devices for sensing the physical ability of a user in the toilet are arranged in the sensor unit 21. Fig. 3 shows an example of the arrangement of two devices used as the sensor unit 21. The first device 211 has a sensor 211a that measures the sitting and leaving movements of the user. In addition, the second device 212 has a communication device 212a for transmitting the measurement results to the cloud.

[0022] The first device 211 is disposed so as to be attached to the top of the toilet seat, and the second device 212 is placed on the floor surface under the toilet seat. The first device 211 and the second device 212 are connected by an interface.

[0023] The sensor unit 21 corresponds to the sensor unit 11 described in the first embodiment. The evaluation unit 22 corresponds to the evaluation unit 12 described in the first embodiment. The notification unit 23 corresponds to the notification unit 13 described in the first embodiment. Therefore, a distance measuring sensor is used for the sensor 211a of the sensor unit 21, similar to the sensor unit 11 described in the first embodiment.

[0024] Next, an overview of the operation of the motor function measuring system 2 will be described with reference to FIG.

[0025] The sensor 211a of the first device 211 starts measurement when it detects that the user has started to sit on the toilet, and ends the measurement when the user has completed sitting on the toilet. Alternatively, the sensor 211a starts measurement when it detects that the user has started to leave the toilet, and ends the measurement when the user has completed leaving the toilet.

[0026] Thereafter, the sensor unit 21 transmits the measurement data acquired by the sensor 211 a of the first device 211 to the cloud constituting the evaluation unit 22 via the communication device 212 a of the second device 212 .

[0027] The cloud, which is the evaluation unit 22, evaluates the motor function based on the measurement data from the sensor unit 21 and accumulates the measurement data. After that, when the evaluation of the motor function is lower than a threshold value preset by the user or caregiver, or has continued to decline for a set predetermined period, the evaluation unit 22 instructs the notification unit 23 to issue a notification to the user or caregiver.

[0028] Here, a mobile terminal 231 carried by the user or the caregiver can be used as an actual item for making the notification in the notification unit 23. The mobile terminal 231 makes the notification in response to an instruction to make the notification received from the evaluation unit 22.

[0029] The item that performs the notification in the notification unit 23 is not limited to the mobile terminal 231, and may be, for example, a display or a speaker. The notification method may be, but is not limited to, sound, video, image, vibration, or the like.

[0030] Furthermore, the user or caregiver who receives the notification from the notification unit 23 can refer to the information recorded in the cloud, which is the evaluation unit 22. This allows the user or caregiver to obtain information on the change in motor function over time due to the yearly transition of motor function as exemplified in Fig. 4, and information on the average distribution from information such as age and gender. In addition, the caregiver or a family member who is far away can use this information to determine whether or not assistance is required for the care recipient.

[0031] Next, an operation example of the motor function measurement system 2 will be described in more detail with reference to Fig. 5. Here, Fig. 5 is a flowchart showing an operation example in which measurement of motor function is triggered when a user enters a toilet and sits on the toilet seat.

[0032] The sensor unit 21 checks whether or not there is a reaction in the sensor 211a of the first device 211 (step S1). If there is no reaction from the sensor 211a (OFF in step S1), the process waits until the sensor 211a reacts. If there is a reaction due to a change in the distance from the sensor 211a to the target object caused by the user starting to sit or leave the seat or opening or closing the toilet seat lid (ON in step S1), the process proceeds to step S2.

[0033] The sensor unit 21 determines whether the reaction of the sensor 211a is the opening and closing of the toilet seat cover, or the action of sitting down or leaving the seat (step S2). The sensor unit 21 can make this determination based on the difference in distance between the seating position and the toilet seat cover position.

[0034] As an example, in the sensor unit 21, the measurement results obtained by the sensor 211a are compared with a predetermined standard by a calculation unit (not shown), thereby determining whether the toilet seat lid is being opened or closed, or whether the person is sitting or leaving the seat.

[0035] If the sensor unit 21 determines that the reaction of the sensor 211a is the opening and closing of the toilet seat cover (opening and closing of the toilet seat cover in step S2), the process is repeated until it is determined that the reaction is the sitting and leaving action. If the sensor unit 21 determines that the reaction is the sitting and leaving action (sitting and leaving action in step S2), the process proceeds to step S3.

[0036] The sensor 211a starts measuring the distance (step S3), thereby acquiring distance measurement data.

[0037] After that, the sensor unit 21 judges whether the sitting down action is completed or not (step S4). For example, the sensor unit 21 can set a threshold value of the distance from the sensor 211a to be measured to the user in advance, and judge that the sitting down and leaving action is completed when the threshold value is exceeded.

[0038] If the sensor unit 21 does not determine that the sitting and leaving actions are complete, that is, if the actions are incomplete (incomplete in step S4), the process returns to step S3 and continues acquiring distance measurement data. On the other hand, if the sensor unit 21 determines that the sitting and leaving actions are complete (completed in step S4), the process proceeds to step S5.

[0039] The communication device 212a transmits the measurement results acquired by the sensor 211a to the evaluation unit 22, which is the cloud (step S5).

[0040] The evaluation unit 22 evaluates the measurement results received from the sensor unit 21 (step S6). Here, Fig. 6 shows examples of distance measurement data when a person with high motor function and a person with low motor function leave their seat.

[0041] Here, an example of an evaluation method in the evaluation unit 22 will be described.

[0042] In FIG. 6, time T 1 is the start time of the leaving action T S Time when the leaving action is completed T e The coefficient k for correcting the influence of the height of the seat and the height of the user's waist is set by taking into consideration that the distance between the user's waist and the sensor 211a at the start of the sitting motion varies depending on the height of the seat and the height of the user's waist. 1 Using and k, the evaluation result R can be calculated using the following formula.

number

[0043] Here, the evaluation unit 22 can evaluate that the smaller the value of the evaluation result R is, the higher the motor function is. max is time T 1 is the rate of change of distance when the amount of change of distance per unit time is maximum,

number

number

[0044] In this case, the evaluation unit 22 evaluates that the motor function is higher as the evaluation result R is larger. max is just one example, and the rate of change of distance over an arbitrary period may be used.

[0045] In addition, as an evaluation method used for comparison with the same age and gender, a threshold value thα set for each age and gender, and a coefficient k that corrects for the effects of seat height and the user's waist height can be used to calculate the evaluation result R using the following formula.

number

[0046] Here, T 1 In the case of evaluation using R, the evaluation unit 22 can evaluate that the motor function is high when the value of the evaluation result R is negative, and that the motor function is low when the value is positive. max When using the above, it is possible to evaluate that the motor function is low when the value is negative and high when the value is positive. Furthermore, when the difference between these two values ​​is large, the evaluation unit 22 can evaluate that the motor function is lower when the motor ability is low, or higher when the motor ability is high, compared to when the difference is small.

[0047] Similarly, the evaluation unit 22 evaluates the sitting motion start time T S From the time when the seating motion is completed, T e Time until T 1 Using the coefficient k, which corrects for the effects of the seat height and the user's waist height, the evaluation result R can be calculated as follows:

number

[0048] In this case, the evaluation unit 22 can evaluate that the motor function is higher as the evaluation result R value is smaller, but can also evaluate that the motor function is low when the evaluation result R value is smaller than the reference value 0.5. This reference value is an example, and may be changed based on statistical data, etc. In addition, the maximum rate of change R max is time T 1 is the rate of change of distance when the amount of change of distance per unit time in is maximum,

number

[0049] Here, the evaluation unit 22 is R max Using coefficient k, which corrects for the effects of seat height and the user's waist height, the evaluation result R can be calculated using the following formula.

number

[0050] In this case, the evaluation unit 22 can evaluate that the motor function is higher as the value of the evaluation result R is larger, but can also evaluate that the motor function is low if the value is too larger than the reference value 140. This reference value is an example and may be changed based on statistical data, etc. In addition, the maximum rate of change R max is just one example, and the rate of change of distance over an arbitrary period may be used.

[0051] That is, the evaluation unit 22 can calculate the evaluation result R by executing at least one of them, and can also perform the evaluation by combining any two or more of them.

[0052] In other words, the evaluation unit 22 evaluates the T 1 Evaluation using coefficient k and seating T 1 Evaluation using coefficient k and R max Evaluation using coefficient k and R maxand an evaluation using the coefficient k. Furthermore, the evaluation unit 22 can perform evaluation using any combination of these.

[0053] In addition, the evaluation unit 22 can use an evaluation method for comparison with the same age and gender, a threshold value thα set for each age and gender, and a coefficient k that corrects for the effects of the seat height and the user's waist height, to determine the evaluation result R as follows:

number

[0054] Here, T 1 In the case of evaluation using R, the evaluation unit 22 can evaluate that the motor function is high when the value of the evaluation result R is negative, and that the motor function is low when the value is positive. max When using the above, it is possible to evaluate that the motor function is low when the value is negative and high when the value is positive. Furthermore, when the difference between these two values ​​is large, the evaluation unit 22 can evaluate that the motor function is lower when the motor ability is low, or higher when the motor ability is high, compared to when the difference is small.

[0055] For example, the threshold value thα or thβ used in these formulas is set from 42 categories, including 20 categories for ages 0 to 100, each for 5 years, and 21 categories for ages 101 and over, plus two categories for gender. In addition, the coefficient k, which corrects the influence of the seat height and the user's waist height, is set appropriately by utilizing the fact that the distance between the person's waist and the sensor 211a at the start of the sitting action changes depending on the seat height and the waist height.

[0056] When the evaluation results of the seating movement and the sitting down movement are significantly different, the evaluation unit 22 can determine which muscle activity has a problem, because the sitting down movement requires concentric contraction of the muscles, whereas the sitting down movement requires eccentric contraction.

[0057] Furthermore, the evaluation unit 22 uses a threshold value set in advance by the user or the caregiver to determine whether or not to issue a notification from the notification unit 23 (step S7).

[0058] Specifically, the evaluation unit 22 judges whether the evaluation result R is lower than a threshold value set in advance by the user or the caregiver, or whether the evaluation result R has been decreasing for a set period by continuing to accumulate past evaluation results R, and issues a notification if this is the case. As an example, the evaluation unit 22 judges whether the evaluation result R is lower than the set threshold value by using a threshold value thγ,

number

number

[0059] If it is determined by these two judgments that a notification is necessary (necessary in step S7), the evaluation unit 22 transmits a signal to the notification unit 23 to instruct the notification unit 23 to generate a notification. Then, the mobile terminal 231 of the notification unit 23 executes the notification in response to the received signal.

[0060] When the mobile terminal 231 notifies the user that the motor function is lower than the threshold, the mobile terminal 231 can display the current motor function evaluation result. When the mobile terminal 231 notifies the user that the motor function has been declining for a certain period of time, the mobile terminal 231 can display the records from the past to the present that have been stored as aging changes. Then, the process ends.

[0061] On the other hand, if it is determined that notification is not necessary (not necessary in step S7), notification unit 23 does not perform notification, and the process ends.

[0062] Note that the above operations have been described as being performed in the motor function measurement system 2 in which the functions of the evaluation unit 22 are performed in the cloud, but the evaluation can be performed in the motor function measurement device 1 described in embodiment 1 without being performed in the cloud.

[0063] This makes it possible to provide the user with an evaluation of their motor function by utilizing distance measurement data of the user's sitting and leaving movements.

[0064] In addition, by checking the evaluation of motor function provided by this device, the user can ascertain the state of his or her own motor function and the associated need for improvement of that function.

[0065] In addition, by recording the assessment of motor function on a regular basis, it is possible to check the change in the assessment of motor function over time, which allows early detection of muscle weakness, etc.

[0066] In addition, in nursing care facilities, etc., by providing the caregiver with an evaluation of the motor function of the person being cared for, it is possible to determine whether the person being cared for requires assistance and to prevent accidents such as falls.

[0067] In addition, by installing a sensor in the toilet where people sit and leave, measurements can be taken every day as the toilet is used, making it easy to perform continuous measurements.

[0068] The sensor for measuring motor function can be installed at the same time as the excretion sensor for identifying excrement, and these can be provided at low cost. In addition, functions such as personal identification can be used at the same time, and the device can be used in public toilets.

[0069] Furthermore, by installing the device in places other than toilets where people sit and get up, such as chairs, it is possible to measure and evaluate motor functions.
