Description

The present invention relates to a load balance display system and program for long-term measurement of the load applied to the lower limbs during walking, which is used in rehabilitation in the fields of medicine, physical therapy, occupational therapy, and the like.

BACKGROUND ART Walking training is performed in rehabilitation for patients who have undergone knee joint surgery, people with physical disabilities, and the like, so that they can perform activities of daily living. Walking training is carried out using parallel bars, crutches, etc. while gradually increasing the load applied to the lower limbs according to the degree of recovery of the patient. Appropriate load control is necessary for effective gait training without giving excessive load to the patient. Therefore, a device capable of accurately measuring the load applied to the left and right lower limbs during walking training has been provided (for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2019-181006

The device described in Patent Document 1 is a foot-mounted load measuring device in which a body consisting of a sole and an upper is equipped with a load sensor and a pressing plate, and the position of the load sensor can be adjusted according to the length of the wearer's foot. (load measuring shoes). This makes it possible to measure the load applied to the lower limbs with high accuracy during walking training in a rehabilitation facility or the like.

However, such conventional load measuring devices are dedicated shoes that are used only during walking training in facilities such as rehabilitation facilities. For this reason, subjects (patients, etc.) have no choice but to continue their daily lives until the next training session, relying on the feeling of the amount of weight they learned through training. The gait trainer (physiotherapist, etc.) could not know it even if I sent it. Continuing to walk for a long period of time with an unbalanced load balance and an excessive load may reduce the effectiveness of rehabilitation and exacerbate the disease. For example, in rehabilitation from leg fractures, hemiplegia, knee joint surgery, and leg muscle weakness, it is necessary to control the load balance applied to the legs over a period of several weeks to a month or longer.

Therefore, in order for gait training instructors to provide more effective instruction and increase the effectiveness of rehabilitation, a technology that can record and evaluate the load on the left and right lower limbs in the patient's daily life over a long period of time is required. Such technology is also useful not only for patients undergoing rehabilitation, but also for analyzing the risk of diseases such as knee osteoarthritis, which develops due to long-term imbalance in load balance, and for understanding muscle weakness in the lower extremities. it is conceivable that.

Includes WANs, LANs, provider equipment, wireless base stations, and the like.
The user terminal 500 is a general-purpose computer, a smart phone, a tablet terminal, a wearable terminal, or the like used by a person to be measured or a walking training instructor. The user terminal 500 is installed with software (such as a general-purpose browser) for communicating with the data server 130 and displaying data received from the data server 130 . The user terminal 500 includes a keyboard, mouse, touch panel, microphone, camera, etc. as input means. again,
Display means such as a display for displaying a screen is provided as an output means. Further, it may be provided with voice output means such as a speaker, and vibration output means such as a vibrator using an eccentric motor.
Note that the number of user terminals 500 may be plural. Also, the user terminal 500 may also serve as the data server 130 .

(Load measuring device)
The load measuring device 110 is used by being attached to the shoes of the person being measured. and a transmission unit 120 for transmitting to.

The measuring section 112 is composed of a seat 114 and a load sensor section 116 .
The sheet 114 is one or a plurality of sheets having an insole shape (foot sole shape) such as a shoe or an elliptical shape. As the material of the sheet 114, an elastic body such as resin or rubber can be appropriately used.
The load sensor unit 116 is a sensor provided on the upper surface of the seat 114 for measuring the load. The measured value of load sensor section 116 may be either a pressure value or a load value. Load sensor unit 11
As 6, a pressure sensor or a load sensor can be used. The pressure sensor is, for example, a resistance wire sensor, a sheet sensor capable of detecting surface pressure, or the like. A piezoelectric type, a strain gauge type, or the like is used as the load sensor, for example. The output of load sensor section 116 is connected to transmission section 120 . There are no particular restrictions on the number and positions of the load sensor portions 116, and for example, the insole-shaped seat 1
A plurality of them may be provided at positions corresponding to the fourteen forefoot regions, middle foot regions, and rearfoot regions. FIG. 1 shows an insole-shaped seat 114 with three load sensors 11 on the forefoot and two on the rearfoot.
6 is provided.

The transmitter 120 is a small communication module capable of communicating with the data server 130 via the network 600 . The method of connecting to the network may be either wireless or wired, but wireless is preferable because it does not interfere with the movement of the person being measured. Wireless connection, for example Wi-F
A system such as i (registered trademark), Bluetooth (registered trademark), or Zigbee (registered trademark) can be used. The transmission unit 120 has an input interface for reading the measured value output by the load sensor unit 116, and has a rechargeable power supply unit such as a battery. Moreover, it is equipped with an arithmetic processing unit, and can perform information processing by executing an arbitrary program.

The transmission unit 120 adds the measured value (load) read from the load sensor unit 116 with the measurement time, the sensor ID (a code for identifying the communication module and the sensor), and the subject ID (a code for identifying the subject). code) to generate load measurement data. The generated load measurement data is sequentially transmitted to data server 130 via network 600 . Note that the time when the load measurement data is received by the data server 130 may be used as the measurement time as long as the communication speed is sufficiently high so as not to affect the measurement results. In this case, the transmitter 120 transmits the load measurement data excluding the measurement time.
Reading of measured values and transmission of load measurement data in the transmission unit 120 takes, for example, from 0.1 seconds to
at intervals of a few seconds. As the measured value, the measured value read from the load sensor section 116 may be used as it is, or the pressure value and the load value may be converted to each other and used. This conversion is performed, for example, by arithmetic processing such as "pressure value×correction coefficient=load value". The correction coefficient includes a sensor pressure-receiving area, a coefficient obtained from the relationship between the weight of the person to be measured and the pressure value or load value to be measured. In the following description, unless otherwise specified, it does not matter whether the measured value is a pressure value or a load value.

Further, the transmission unit 120 may include storage means 122 such as removable storage media such as RAM, ROM, and SD card. The load measurement data may be transmitted when the load measurement data is accumulated in the storage means 122 and reaches a certain amount, or when communication with the data server 130 becomes possible. Even if there is a period when communication is not possible, load measurement data is sent to the data server 1
30 can be sent.

The load measuring device 110 configured as described above includes, for example, the insole shape measuring unit 11
2 is put as an insole inside the shoe worn by the person to be measured, and the transmission unit 120 is attached to the upper (upper surface) of the shoe or the like, so that the device can be attached to various shoes. When the person to be measured walks wearing shoes equipped with the load measuring device 110, the load sensor unit 116 sequentially measures the load applied to the leg, and the transmission unit 120 generates load measurement data including the measured value (load). and transmits it to the data server 130 . Note that the load measuring device 110 is used by being attached to each of the left and right shoes.
If it is sufficient to measure the load on one leg, it may be attached to only one shoe.

(data server)
The data server 130 mainly stores load measurement data received from the load measuring device 110 , calculates load balance based on the load measurement data, and provides data to the user terminal 500 .

The data server 130 includes, as a hardware configuration, computing means/control means such as a CPU,
It can be configured by a computer equipped with storage means such as HDD, RAM, and ROM, input/output means (display, keyboard, mouse, touch panel, etc.), and communication means such as a network interface. The functions of the data server 130 described below are implemented by programs installed in the data server, computing means, control means, storage means, etc., or a combination thereof. The data server 130 can execute a load balance display program as one of these programs. The data server 130 acquires the load data from the load measuring device 110 and calculates the load balance by processing the load balance display program.

The data server 130 includes a communication unit 132, a storage unit 134, a load balance calculation unit 136, a display data generation unit 138, and an advice information recording unit 140 as functional configurations.

The communication unit 132 communicates the load measuring device 1 with a predetermined communication protocol via the network 600.
10 and the user terminal 500 to exchange data.

The storage unit 134 stores load measurement data 200 received from the load measuring device 110 via the communication unit 132 and load balance evaluation results 300 . The load balance evaluation result 300 will be described later.

When the data server 130 receives the load measurement data from the load measuring device, the data server 130 stores the received data in the storage unit as the load measurement data 200 shown in FIG. The load measurement data 200 is
It stores and accumulates the load measurement data received from the load measuring device 110, and stores a measurement time 202, a sensor ID 204, a subject ID 206, and a measured value 208 in association with each other. Here, as described above, the reception time of the load measurement data may be used as the measurement time 202 . A record of load measurement data 200 is uniquely identified by a combination of measurement time 202 and sensor ID 204 .
The storage unit 134 has sufficient storage capacity to store load measurement data including loads continuously measured by the load measuring device 110 for one month or longer.

Note that the storage unit 134 may store subject information 400 in which the subject ID 206, the subject's name, the subject's weight, the load balance automatic calculation cycle, and the like are associated with each other.

The load balance calculation unit 136 calculates the load balance based on the load measurement data 200 accumulated in the storage unit 134 , generates the load balance evaluation result 300 , and stores it in the storage unit 134 .

The load balance is the load applied to the left and right lower limbs of the subject. The display method of the load balance is not limited as long as it can be calculated from the load measurement data 200 . Examples of the load balance include "maximum/average load", "left/right ratio of maximum/average load", "body weight ratio of maximum/average load", and "accumulated load" applied to each leg. Examples of these calculation methods are described below.

Maximum/average load: First, from the load measurement data 200, all the records corresponding to the target subject ID 206 whose measurement time 202 is within a predetermined period are extracted.
4, and time-series measured values 208 are obtained for each sensor ID 204 . Next, regarding the time-series measured values 208, a section in which the measured values 208 continuously exceed a threshold value (predetermined value for determining that a load has been applied) is defined as one step, and the maximum measured value in that section is the load for one step. Determination of the one-step interval and calculation of the load for one step are performed for the entire time-series measured values 208 . Then, the maximum load is selected from among the loads for one step and taken as the maximum load as the load balance. Further, the average value obtained by dividing the total load for all steps by the number of steps is used as the average load as the load balance. Here, the average value may be an average for a plurality of consecutive steps, or may be calculated as an average load for ten consecutive steps, for example.

Left-right ratio of maximum/average load: Calculate the ratio of the maximum/average load for each of the left and right feet when the total value of the maximum/average load of the left and right feet calculated by the above method is taken as 100%.
It is the left-to-right ratio of the average load.

Weight ratio of maximum/average load: The ratio of the maximum/average load calculated by the method described above to the body weight of the person to be measured is calculated and used as the ratio of maximum/average load. As the weight of the subject, the weight of the subject stored in advance in the subject information 400 or the maximum load measured with the foot capable of bearing the full load is used.

Cumulative load: The cumulative load is obtained by totaling the maximum load for all steps obtained by the method described above. As another method of calculating the integrated load, all the measured values 208 within a predetermined period that exceed a predetermined threshold for determining that a load has been applied may be summed up to obtain the integrated load.

The obtained load balance may be calculated as a value for each sensor ID 204,
Grouping may be performed for each region of the sole to which the load sensor unit 116 is attached (forefoot, middle foot, rearfoot), and the sum or average may be calculated. In addition, the predetermined period in the above calculation is
Set according to the purpose of evaluation. For example, when evaluating in real time, it is set as short as the last few seconds. When conducting long-term evaluation, a period of one month or more is set, or the load balance for one day is calculated continuously for 30 days or more.

The calculation of the load balance is performed based on the conditions designated by the user terminal 500 when the user terminal 500 requests the display of the load balance evaluation result 300 .
Further, the calculation of the load balance may be automatically performed each time a certain period of time elapses. For example, it is a period such as every day, every week, or every month. Every time a certain period of time elapses, the load balance is calculated from the load measurement data 200 for the most recent period. For specifying the period, the load balance automatic calculation period or the like stored in the subject information 400 is used.

The load balance calculator 136 generates a load balance evaluation result by adding calculation conditions and the like to the calculated load balance, and stores it in the storage unit. FIG. 3 is a diagram showing the load balance evaluation result 300 stored in the storage unit 134. As shown in FIG. The load balance evaluation result 300 has the evaluation result ID 3
02, registration date/time 304 indicating data registration/update date/time, subject ID 206, target data period 306, calculated load balance 308, and walking training instructor 310 are stored in association with each other. A record of the load balance evaluation result 300 is uniquely identified by an evaluation result ID. The target data period 306 is the range of the measurement times 202 of the load measurement data 200 used to calculate the load balance 308 .

The load balance evaluation result 300 further includes advice information 312 and subject comment 3.
14 may be stored (FIG. 3).
The advice information 312 is, for example, advice from the walking training instructor 310 regarding optimization of the load balance of the subject. After the walking training instructor browses the load balance evaluation result 300, it is recorded as necessary, and is data in various formats such as text, voice, image, and moving image. For example, it is data such as text information and voice information about instruction content, and photographs and videos for pointing out appropriate walking.
Subject's comments 320 are impressions of the subject who viewed the load balance evaluation result 300 during the measurement period, opinions on the advice information 312, and the like. Advice information 31
2, data in various formats such as text, voice, image, and moving image can be used.

The display data generation unit 138 generates display data for displaying the load balance evaluation result on the user terminal 500 and transmits the display data to the user terminal 500 . The display data is generated by extracting the record of the load balance evaluation result 300 designated from the user terminal 500 and based on this.

First, when accessed from the user terminal 500, the display data generator 138 urges the user to designate a record of the load balance evaluation results 300 for which display data is to be generated.
FIG. 4 is an example of a UI screen for designating a record to be displayed from among the load balance evaluation results 300 from the user terminal. A list 151 of the load balance evaluation results 300 stored in the storage unit 134 is displayed on the upper part of the UI screen 150, and the record is selected with a check box 151C arranged next to each record. After selecting a record on the user terminal 500, when the "Display" button 151B is pressed, the identification information of the selected record (evaluation result I
D) is sent to the data server 130 . The display data generation unit 138 extracts the selected record from the load balance evaluation result 300, generates display data, and transmits the display data to the user 500 terminal.
Note that if the evaluation result ID to be displayed is already known, the user terminal 50 directly without going through the UI screen.
You can specify from 0.

If the record that the user wants to display is not found in the load balance evaluation results 300 , the user transmits to the data server 130 the calculation conditions for the load balance that the user wants to calculate. Load balance calculation conditions include target data period 306 (range of measurement time 202 of load measurement data 200), subject ID 206, and load balance display method (maximum/average load, left-right ratio of maximum/average load, etc.). is.

The load balance calculation conditions are transmitted via the UI screen 150 shown in FIG. 4, for example. The lower portion of the UI screen in FIG. 4 is for the user to specify conditions and instruct calculation of the load balance and generation of display data. In the user terminal 500, an input field 152A for the subject ID, an input field 152D for the target data period, and a check box 15 for designating the load balance display method.
The calculation conditions are transmitted to the data server 130 by specifying the calculation conditions with 2C and pressing the "calculate" button 152B. When the data server 130 receives the calculation conditions, the load balance calculation unit 136 calculates the load balance under the specified conditions and stores it in the load balance evaluation result 300 . The display data generation unit 138 extracts a record newly accumulated in the load balance evaluation result 300, generates display data, and transmits the display data to the user 500 terminal.

The display data generated by the display data generation unit 138 is not particularly limited as long as it is in a format that can be browsed on the user terminal. For example, it is possible to select various data formats, such as using the information in the record of the load balance evaluation result 300 as display data as it is, or generating tabular text data or binary data as display data. When the user terminal 500 is equipped with voice output means or vibration output means, voice data for conveying information in the record (for example, reading voice, warning sound, etc.) and waveform data for outputting predetermined vibration are generated. may Alternatively, a UI screen using a graph or the like created from information in the record may be generated and used as display data. The UI screen may be generated on the user terminal 500 side using the received display data.
