Description

  The present invention relates to a fall risk check system and a fall risk check program for easily checking a fall risk by a person to be measured.

  Along with the increase in the elderly population, the number of elderly people who need support and care for daily life is rapidly increasing, and an increase in the medical economy such as medical expenses and nursing care costs has become a social problem. According to the 2010 National Life Survey, the factors leading to support and long-term care are the highest in motor organ failure due to fractures / falls, joint diseases, spinal cord injury, etc., followed by cerebrovascular disease and dementia. It has become. The function of the musculoskeletal organs, unlike other organs, has continued to decline over the age of 40, and it has been found that they have a wide range of muscle strength, endurance, bone density, flexibility, responsiveness, ability to maintain balance, etc. ing. Along with this, `` locomotive syndrome '' refers to a state in which daily activities such as walking, standing up, climbing stairs, luggage carrying capacity, etc. gradually become hindered, and the mobility function has deteriorated due to musculoskeletal damage due to aging. Has been proposed.

  While motor function declines with age, self-recognition of motor function has a strong image at the peak of motor ability, so that there is a discrepancy between the motor function recognized as the actual motor function. For this reason, a prediction difference with respect to one's motor ability is induced, such as "I didn't go up more than I thought" or "I thought I could straddle that level of difference". Stumbling and falling while walking is caused by such a prediction difference when the athletic ability kept as an image is not exhibited. Therefore, it is necessary to carry out health management in daily life so as to be aware of the difference between the actual motor function and the recognized motor function, to prevent falls due to mispredictions, and to prevent musculoskeletal disorders.

  Therefore, conventionally, as health management in daily life, a device that can obtain a health management effect by measuring the center of gravity of the person being measured, simply evaluating the motor function based on the measured value, and quantitatively capturing the motor function Was previously proposed.

  As such an apparatus, the time until the movement and the position of the center of gravity are stabilized by measuring the position of the center of gravity of the person to be measured, displaying the target object of the center of gravity movement together with the position of the center of gravity, and quickly moving the center of gravity. There is known an apparatus (see Patent Document 1) that measures a time until a score is obtained by calculating an index relating to athletic ability from each measured time and physical information of a measured person. Also, instruct the subject to perform physical exercise, detect the center of gravity of the subject based on the load detected with the exercise, and evaluate the motor function of the subject based on the displacement of the center of gravity An apparatus (see Patent Document 2) is proposed.

Japanese Patent No. 3871247 Japanese Patent No. 4990719

  However, the above-mentioned conventional apparatus measures the continuous switching operation from the movement of the person to be measured to the static, and from the static to the dynamic, and performs the determination based on the physical fitness diagnosis test. Not suitable for evaluation of motor function. In addition, since a predetermined exercise is repeated regularly to evaluate the motor function of the measurement subject, it takes time to calculate the evaluation.

  Furthermore, in order to prevent falls, it is important to maintain and improve the body's flexibility and muscular endurance to maintain posture in addition to the ability to maintain balance. With the above-mentioned conventional devices, only the ability to maintain balance is evaluated. However, it was not possible to measure the overall judgment factors of fall risk and suggest fall risk.

  The present invention has been made to solve the above-described conventional problems. For example, a weight scale or a body fat scale is used so as to prevent a disease caused by obesity by weight measurement. The present invention provides a fall risk check system that can check the fall risk of a measurer by a simple method and can support the fall prevention of the subject.

  For this reason, the fall risk checking system of the present invention includes a load distribution detecting means for detecting the load distribution of the left and right feet in a state where the subject is standing on both feet, a weight measuring means for detecting the weight of the subject, One-foot standing time measuring means for measuring the time during which the measurer can maintain the standing state of one foot, a computing means for calculating the flexibility of the back muscle of the subject based on the one-foot standing time, and the computing means The fall risk analysis means that analyzes the fall risk of the subject based on the flexibility of the back muscles, the detected load distribution and weight, the measured time for standing on one leg, and the analysis result by the fall risk analysis means are displayed. The first feature is that the display means is provided.

  In addition, an input means for inputting the physical information of the person to be measured is provided, and the display means displays the second feature, wherein the calculation means calculates the center of gravity of the person to be measured based on the weight of the person to be measured. A third feature is that a left-right balance is calculated, a foot balance ratio for each left and right foot is calculated based on the detected load distribution for each left and right foot of the measurement subject, and displayed on the display means.

  Furthermore, the fourth feature is that the time until the variation of the load on the person's standing foot converges and stabilizes is measured and displayed on the display means.

  In addition, the program of the present invention measures the weight of the person to be measured, calculates the left / right balance of the center of gravity of the person to be measured, and the ratio of the center of gravity of the left and right, and the load distribution for each left and right foot of the person to be measured. A step of calculating a foot balance ratio for each foot, a step of calculating the flexibility of the subject's back muscles based on a person's standing time for one leg, and a subject to be measured based on the calculated flexibility of the back muscles And a step of displaying the left / right balance of the center of gravity of the person to be measured, a foot balance ratio for each of the left and right feet, a standing time for one foot, and a fall risk.

The weight measuring device 22 generates a signal corresponding to the weight of the object on the detection table 2 or the person to be measured (floor reaction force) using, for example, a load cell or a piezoelectric element as used in a general weight scale. To do. In addition, load distribution measuring devices 23 are built in the lower part of the foot position guideline 21, respectively, and the load distribution on the sole of the foot is detected in a state where the person to be measured stands on the foot position guideline 21. As shown in FIG. 1, the load distribution measuring device 23 arranges sensors in a grid pattern, for example, and detects the load distribution on the sole with the intersection of the sensors as a sensing point. A power switch 24 for turning ON / OFF the detection table 2 is provided on the rear (lower side in FIG. 1) side surface of the detection table 2.

  Further, as shown in FIG. 2, the detection table 2 wirelessly transmits the MPU 25 connected to the weight measurement device 22 and the load distribution measurement device 23 and the data processed by the MPU 25 to the terminal device 3. The wireless device 26 is built in. The MPU 25 includes an arithmetic device 251 that performs arithmetic processing in accordance with a predetermined program based on signals detected from the weight measuring device 22 and the load distribution measuring device 23, and an A for converting the detected analog value into a digital signal. A / D conversion device 252 and a timepiece device 253 which is a time measuring means for measuring time related to date management and load distribution are included.

  As shown in FIG. 1, the terminal device 3 includes a display unit 31 for displaying measurement values received from the detection table 2, information on the person to be measured, the name, sex, age, height, and foot size of the person to be measured. The operation unit 32 for inputting information related to the body of the person to be measured, a control unit incorporating a CPU, ROM, RAM, etc., receives data from the detection table 2, calculates and analyzes results based on the data An application program is provided. The display unit 31 is composed of a display such as an LCD or a CRT, for example, and displays various input data via an installed application program under the control of the CPU. The operation unit 32 includes a keyboard composed of, for example, data input keys for inputting numerical values, characters, etc., up / down / left / right movement keys for performing data selection, feeding operations, and various function keys. The key press signal is output to the CPU. As described above, the terminal device 3 is a device based on a general-purpose personal computer. In addition to using a notebook type terminal as illustrated, for example, a dedicated display unit 31, an operation unit 32, and a control unit are separately provided. It may be a device.

  Next, the operation of the fall risk check system 1 according to the present invention will be described. The measured person presses the power supply of the terminal device 3 and the power switch 24 to turn on the power of the detection table 2, starts the application program of the terminal device 3, and causes the display unit 31 to display the top screen 5 of the application program. (Step S1). The person being measured displays “Measuring person” on the display screen. In the following, the above-described measured person will be described as a measuring person.

  As shown in FIG. 4, the measurer information button 51 is pressed on the top screen 5 on which the application program is activated to display the measurer list screen 6 shown in FIG. 5, and the measurer is selected (step S2). . If the measurer is not displayed in the list, that is, if a new measurement is to be performed, the new registration button 61 is pressed to display the measurer registration screen 7 shown in FIG. On the measurer registration screen 7, measurer information 71 such as the name, sex, age, height, and foot size of the measurer is input by the operation unit 32, and a registration button 72 is pressed to perform new registration. The input measurer information 71 is recorded in a storage device such as a RAM or a ROM of the terminal device 3, and this information is extracted and displayed on the measurer list screen 6. After confirming the measurer on the measurer list screen 6 and selecting and pressing the end button 62, the measurer information of the selected measurer is displayed on the top screen 5 shown in FIG. When the measurer information displayed on the top screen 5 is different from the actual measurer, the measurement cancel button 53 is pressed to select the measurer again.

  Subsequently, after pressing the measurement start button 52 on the top screen 5, it is determined whether the measurer stands on the detection table 2 and the measurement program is started (step S3). The measurer stands on both sides of the detection table 2 using the foot position guideline 21 displayed on the surface of the detection table 2 as a guide to the foot shape close to his / her foot size, so that the detection table 2 automatically measures the weight ( Step S4), left / right balance measurement (step S5), and stabilization time measurement (step S6) are measured sequentially or simultaneously, and the data is transmitted to the terminal device 3.

  The weight measurement (step S4) is measured using the weight measuring device 22 at the four corners described above, and the total value of the load signals obtained at various places is calculated by the calculation device 251 as the weight value of the measurer, and the top. It is displayed on the screen 5. In the left / right balance measurement (step S5), the left / right balance of the center of gravity is calculated by the calculation device 251 and displayed on the top screen 5 based on the difference between the load signals detected by the weight measurement devices 22 at the four corners. Here, the left / right balance is displayed by the CPU in the terminal device 3 in a time series graph in which the load signal value is within the stable time, and the ratio of the center of gravity position is calculated and displayed below the graph. Further, when the variation in the load detected by the load distribution measuring device 23 becomes almost zero and the center of gravity is stabilized, the characters “stable” are displayed on the top screen. The load distribution detected by the load distribution measuring device 23 is arithmetically processed by the CPU in the terminal device 3 and is displayed graphically as a foot balance. For example, the load distribution corresponds to a part such as a heel, a thumb ball, and a little finger ball for each foot. Displayed as a percentage. The stable time measurement (step S6) is performed by measuring the fluctuation of the load detected by the weight measuring device 22 or the load distribution measuring device 23 from the time when the weight measuring device 22 or the load distribution measuring device 23 starts detecting the load by the clock device 253. Is measured until it becomes almost zero (posture in a standing position), and is displayed on the top screen 5 as a stable time.

  After the measurement person is in a standing posture, that is, after the measurement up to step S6 is completed, the measurement of one leg is started (step S7). For example, a step such as generating a buzzer sound from the terminal device 3 may be inserted so that the measurer himself can confirm the timing of starting the next measurement.

  In step S7, measurement of standing on one foot is started when the load on one foot among the loads on both feet detected by the weight measuring device 22 becomes zero. That is, while the weight measuring device 22 detects the load on both feet, the measurement standby state is entered. When the measurer starts standing on one foot (when the load on one foot becomes zero), the timepiece device 253 is automatically activated, and the measurement is completed at the time when the standing on one foot is completed, or when time-out occurs ( Step S8). Here, the end of standing on one foot indicates that the weight measuring device 22 detects the load again, and indicates that the foot lifted upward by the measurement subject is landed on the measuring device 2 again. The timeout means that the measurement is finished in a certain time when standing on one foot does not end. As the one leg standing time, the time measured as one leg standing time is displayed on the top screen 5.

  When the measurement up to step S8 is completed, various measurement results based on the measurement values are calculated or analyzed (step S9). As the measurement result, flexibility, fall risk (locomo estimated value), and diagnosis comment are calculated and displayed on the top screen 5 as diagnosis comments.

  When calculating the flexibility, it is calculated by the following correlation equation 1 based on the correlation between the measured one-leg standing time and the flexibility. Here, y indicates flexibility, and x indicates the standing time for one leg.

<Correlation formula 1>
y = 0.0.1088x + 25.442

Correlation formula 1 is a correlation formula obtained by the inventors performing regression analysis on the measurement results of the one-leg standing time and the long-seat body forward bending in the conventional physical strength measurement. As shown in FIG. 7, these parameters have a correlation contribution ratio R ² of 0.2855, and are correlated. Flexion of the back muscles is necessary for long-body forward bending, and in the present invention, the results obtained from the correlation equation obtained by regression analysis of the measurement results of the standing time of one foot and the long-body forward bending are obtained. It is an index for estimating the flexibility of the back muscles.

  As described above, in order to prevent a fall, in addition to balance ability such as balance, flexibility of the body is necessary. Therefore, it is possible to estimate the risk of falls from the left / right balance of the center of gravity and the flexibility of the body. In the new physical fitness test at the Ministry of Education, Culture, Sports, Science and Technology, as shown in FIG. The score of the person to be measured is given, and the physical strength of the person being measured is evaluated by the total score. In the present invention, the fall risk of the measurement subject is comprehensively analyzed from the measurement result of the measurement subject's age, sex, one leg standing time (one leg standing time) and the value obtained by the correlation equation 1. For example, if the person to be measured is female, the age is 42 years, and the measurement result of one leg standing time is 33 seconds, the value obtained by the correlation equation 1 is y = 29.0324, and the score table shown in FIG. Although the balance maintenance ability is moderate, it is analyzed that the flexibility is low and the risk of falling is high. As the threshold for performing the fall risk analysis, known data may be used as shown in FIG. 8, or the fall risk may be determined by providing a predetermined threshold for analysis. As described above, the present invention includes the fall risk analyzing means for analyzing the fall risk of the measurement subject based on the flexibility of the back muscles.

  Diagnosis comments include measurement results such as stability time, standing time for one foot, load distribution for each left and right foot of the subject, left and right balance of the subject's center of gravity, foot balance ratio for each foot, calculation results such as flexibility, Based on the analysis result such as the fall risk, a predefined diagnostic comment is displayed on the top screen 5. Therefore, the person to be measured can obtain a diagnostic comment on his / her fall risk by a simple method of standing on the detection table 2 and standing on one foot.

  The diagnosis of locomotive syndrome is performed by judging the degree of independence in daily life and evaluating motor functions based on the function evaluation items established by the Japanese Orthopedic Association. Functional evaluation items include whether you can wear socks on one foot, whether you trip or slip in the house, whether you need a handrail to climb the stairs, Whether it is possible to cross, whether it is possible to walk for 15 minutes continuously, whether it is difficult to bring back about 2kg of shopping (about 2 liters of milk cartons), and somewhat in the house Items related to motor functions in daily life, such as whether or not heavy work (use of vacuum cleaners, raising and lowering futons, etc.) is difficult. Each item is self-evaluated, and if even one applies, locomotive syndrome It is determined that there is a risk. Therefore, in the present invention, for example, when the possible time for standing on one foot is extremely short, it is determined that it is impossible to wear socks on one foot, and it can be estimated that there is a risk of locomotive syndrome. The length of time for which one leg can stand is calculated by a predetermined formula using age and gender, or a certain time may be determined as a border line. The presence or absence of the risk of locomotive syndrome determined in this way is displayed on the top screen 5.

  When data such as measurement results and calculation results displayed on the top screen 5 are to be saved, the measurement data save button 54 on the top screen 5 is pressed and saved in a storage device such as RAM or ROM of the terminal device 3. The measurement is completed (step S11). In addition, the measurement result is printed from the printer device 4 by pressing the print button 55. The printer device 4 can use various devices as long as the display screen and the measurement result can be printed. For example, instead of the printer device 4, a card printing device or the like that can print a barcode on a plastic card is used. In addition to the measurement results and personal information, a two-dimensional barcode can be printed on the card.
