In general, sarcopenia refers to a decrease in body muscle mass, and generally refers to a decrease in muscle mass associated with aging, and the muscle at this time refers to a skeletal muscle. The causes of sarcopenia are very diverse, and it is known that the state of sarcopenia can be alleviated to some extent if continuous strength training or nutritional treatment is well implemented. On the other hand, clinically, such sarcopenia has a high disease morbidity due to frailty itself, and it is known that the prognosis is poor when receiving trauma or major surgery.

Accordingly, many studies for diagnosing such sarcopenia are being conducted, and as an example of a technique for diagnosing such sarcopenia, Korean Patent Registration No. 10-2021291 discloses: a calculator that calculates a lean body mass index from measured body composition information; and a diagnostic unit for judging whether or not sarcopenia is present by comparing the calculated lean body mass index and sarcopenia standard value, wherein the sarcopenia standard value is determined by the sarcopenia diagnosis device determined from the data on the lean body fat distribution extracted from the statistical population. An apparatus and method for monitoring sarcopenia based on fat index have been disclosed.

However, in the conventional method for diagnosing sarcopenia, the sarcopenia diagnostic parameters are as much as the diagnosis of sarcopenia through the measured body fat index and the sarcopenia reference value determined from the lean body fat distribution data extracted from the population. There was a problem in that it was difficult to obtain more reliable results in diagnosing sarcopenia because it is set only as the lean body fat value.

The angle measuring sensor unit 243 is installed on the knee side where the first measuring member 241 and the second measuring member 242 face each other, so that the first measuring member 241 and the second measuring member 242 are relative to each other. It is configured to measure an angle.

Accordingly, the resistance measuring circuit unit is configured to measure a variable resistance value and transmit it to the central server 500 . Then, the central server 500 can calculate the angle of the knee joint by calculating the angle between the first measuring member 241 and the second measuring member 242 through the measured resistance value.

The angle measuring means 240 may be configured to measure the changed angle using a sensor such as a potentiometer and a strain gauge in addition to the configuration of the present invention described above, and a passive angle measuring meter equipped with a goniometer may also be applied. Of course.

On the other hand, the angle measuring means 240 is combined with the aforementioned muscle mass measuring module 120 and the volume measuring module 110 without the need to separately attach and install the measurement target, so that the muscle mass and volume measurement and performance ability can be measured at the same time. It can be configured, through which the measurement time can be shortened, as well as various measurements can be made with one wear, so the workability is good, and easy measurement is possible only by wearing it.

Although not shown, the sarcopenia diagnosis platform of the present invention can measure muscle tone and add the measured muscle tone value as a sarcopenia diagnosis parameter. In this case, the sarcopenia diagnosis platform is configured to further include a muscle tone measurement unit, and the muscle tone measurement unit can be configured to measure muscle tone through high and low surface EMG (EMG) signals using a patch-type sensor. have.

Hereinafter, a detailed configuration for analyzing and determining whether or not sarcopenia of the analysis module 520 in the central server 500 will be described in detail.

First, the analysis module 520 may be configured to calculate the muscle mass per unit volume through the muscle mass measured by the muscle mass measuring module 120 and the volume value calculated by the volume measuring module 110 .

To this end, the analysis module 520 receives the muscle mass data of the quadriceps and the lower thighs from the muscle mass measurement module 120 , and calculates the volumes of the quadriceps and the lower thighs through the data received from the volume measurement module 110 .

At this time, the analysis module 520, in order to calculate the volume, the first strep 111, the second strep 112, and the third strep 113 through the short-circuit contact position received from the circumference measurement unit 115. ), and calculates the circumference lengths of each of the fourth straps 114 . In this way, when the respective circumference lengths are calculated, the calculated circumference lengths, the separation distance between the first strep 111 and the second strep 112 and the separation distance between the third strep 113 and the fourth strep 114 are calculated. It is configured to calculate the volume of the gluteus maximus and the lower extremity, respectively, and to calculate the volume of the lower extremities through this.

On the other hand, when the volume measurement module 110 is a resistance measurement unit such as a strain gauge, the analysis module 520, the first strep 111 and the second strep 112 through the electrical resistance value received from the resistance measurement unit. And, the third strap 113 and the fourth strap 114 can be configured to calculate the circumference of each and to calculate the volume through this.

Accordingly, the analysis module 520 can calculate the muscle mass per unit volume of the lower extremities through the calculated volume values and muscle mass values of the lower extremities.

On the other hand, the analysis module 520 may be learned through a deep learning algorithm based on Deep Neural Network (DNN) learning, in order to verify and improve the accuracy of the muscle mass measured by the muscle mass measurement module 120, After completion of learning, it may be configured to calculate a more accurate muscle mass based on the bioimpedance data of the muscle mass measurement module 120 .

Here, the deep neural network structure is composed of an input layer composed of impedance values according to frequencies derived from the muscle mass measurement module 120 and muscle mass values derived through the muscle mass measurement means 150 as shown in FIG. 7 . It consists of an output layer and a plurality of hidden layers, and the number and weight of the hidden layers at this time can be designed in various ways.

On the other hand, the muscle mass measuring means 150 can apply the muscle mass measuring means 150 by a known dual energy x-ray absorptiometry (DXA), and is configured to calculate the muscle mass through this it is preferable This is because this dual-energy X-ray absorptiometry method has a small error range when compared with the muscle mass value calculated through MRI measurement, and is a measurement method that can obtain accurate and reliable muscle mass data.

Next, the analysis module 520 calculates a performance index and a muscle strength index through the respective data on physical ability, walking speed, exercise ability, and grip strength.

To this end, the analysis module 520, the physical ability test module 210, the walking speed measurement module 220, and the simple physical function test received from the exercise ability measurement module 230, the physical ability value, the walking speed value, It may be configured to calculate a performance index and a muscle strength index based on a muscle strength value and an exercise ability value such as a joint angle value and a climbing speed value.

On the other hand, the sarcopenia diagnosis platform of the present invention transmits each data of the muscle mass measurement unit 100, the performance measurement unit 200, and the muscle strength measurement unit 300 to the central server 500 through a wired/wireless network such as Bluetooth. may be configured, and the measured raw data may be transmitted to the mobile terminal 600 including a PC or a smart portable terminal.

Hereinafter, a sarcopenia analysis method for analyzing the presence or absence of sarcopenia of a subject to be measured using the aforementioned sarcopenia diagnosis platform will be described. Here, since the description of each configuration of the sarcopenia diagnosis platform has been described above, the description thereof will be omitted.

Referring to FIG. 8 , first, by using the hardware measuring device 400, muscle data including the muscle mass, muscle strength, and physical activity performance of the subject to be measured is measured (S10).

9 shows detailed steps for measuring such muscle data. Referring to the drawings, the measurement of muscle data includes a step ( S11 ) of the volume measuring module 110 measuring a set body part volume of a measurement target, and a muscle mass measurement in which the muscle mass measuring unit 100 measures the muscle mass of the body part. Step (S12), a physical ability measurement step (S13) in which the performance measurement unit 200 measures the physical activity performance of a body part, and a muscle strength measurement step in which the muscle strength measurement unit 300 measures the grip strength of the person to be measured (S14) may be included.

First, in the present invention, the muscle mass is calculated as a muscle mass index by measuring the muscle mass per unit volume, and for this purpose, the volume and the muscle mass of the corresponding body part are respectively calculated.

Looking at the step of calculating the muscle mass of the body part, in the present invention, the body part represents the lower extremities including the quadriceps and lower extremities, and the volume of the body part measures the volume of the lower extremities. Here, the calculation of the volume value of the lower extremities may be calculated by adding the volume value of the thigh muscle and the volume value of the lower leg calculated by the volume measurement module 110, respectively.

In detail, the thigh muscle is considered to have a truncated cone shape based on the first strep 111 and the second strep 112, and similarly, the lower thigh muscle has a truncated cone shape based on the third strep 113 and the fourth strep 114. Considering that it has a shape, the volume of the lower extremities can be calculated by calculating the volume of these two imaginary truncated cones.

Accordingly, the volume of each of the quadriceps and lower thighs may be calculated by Equation 1 for calculating the truncated cone volume. Considering this, in the case of the thigh muscle, the circumference lengths of the first and second streps 111 and 112 measured through the circumference measuring unit 115 and the measured first and second streps 111 and 112 are measured. ) by substituting the vertical separation distance in Equation 1 to calculate the volume. Similarly, in the case of lower work, the circumference of the third strep 113 and the fourth strep 114 measured through the circumference measuring unit 115 and the measured third strep 113 and the fourth strep 114 are By substituting the vertical separation distance into Equation 1, the volume can be calculated.

Equation 1

Here, r1 is a radius with respect to the circumference of the first strap 111 or the third strap 113 , and r2 is a radius with respect to the circumference of the second strap 112 or the fourth strap 114 .

Next, we will look at the steps of measuring the muscle mass.

First, before examining the method of measuring muscle mass, the muscle mass in the present invention may target appendicular skeletal muscle mass (ASM), and in this case, the bone mineral mass ( The sum of muscle mass limiting bone mineral content) can be expressed as appendicular skeletal muscle mass (ASM).

Accordingly, in the present invention, the muscle mass, as the muscle mass of the lower extremities, can be represented by the muscle mass of the femur of the femur and the lower quadriceps muscle of the lower femur, and the required volume can also be set to the corresponding volume of the thigh and lower leg.

On the other hand, the method of measuring the muscle mass in the present invention can be applied to the muscle mass measurement by the body electrical resistance analysis (BIA; bioelectric impedance analysis). This body electrical resistance analysis method sends a minute alternating current to the body and measures the body fat mass and muscle mass through the impedance generated through it. It has the advantage that it can be easily measured and can be used even in reclined patients.

Meanwhile, the central server 500 of the present invention may be learned by a deep learning algorithm based on deep neural network learning in order to improve the accuracy of muscle mass measurement and verify the muscle mass calculated through the above-described bioimpedance. In this case, the deep neural network structure is composed of an input layer composed of impedance values according to frequencies in the muscle mass measurement module 120 , an output layer composed of muscle mass values derived through the muscle mass measurement means 150 , and a plurality of hidden layers. Through this, when learning is completed, it is configured to calculate more accurate muscle mass based on the impedance value.

Here, the muscle mass measuring means 150 applies a means for measuring muscle mass by X-ray absorptiometry (DEXA), and the muscle mass value measured by this X-ray absorptiometry is deeply It is trained as the output layer of the neural network. Meanwhile, the measurement of muscle mass may be performed using an X-ray absorptiometry that can obtain a more reliable muscle mass data value, but is not limited thereto.

When the volume value and the muscle mass value are respectively calculated by the volume measuring module 110 as described above, the central server 500 can calculate the muscle mass per unit volume.

When the amount of muscle per unit volume is calculated in this way, physical activity performance is measured to measure the quality of the muscle.

Here, the physical activity performance ability is calculated by measuring the physical activity performance ability of the subject to be measured for a set time through the performance measurement unit 200, and includes a short physical performance battery (SPPB), walking speed, and standing and walking. Tests (timed get-up-and-go test, TUG), balance, and stair climbing can be measured as metrics.

Here, the criteria of each measurement item for measuring physical activity performance ability may be set differently according to male, female, age, and the like.

Meanwhile, in the present invention, the performance measurement may be performed simultaneously when the muscle mass is measured by the muscle mass measurement unit 100 described above.

When physical activity performance is measured in this way, muscle strength is measured. The muscle strength measures the strength of the person to be measured through the strength measurement unit 300 , and a handgrip strength method is applied as a strength measurement method.

For this, a known knee flexion/extension technique can be used as a muscle strength measurement method, but in this case, a separate measuring machine is required, and the user's training to instruct the test target (patient) to be measured, the machine Since the space occupied, etc. are required, many restrictions are followed, so it is preferable to apply a grip strength measurement method that can be easily used clinically in the present invention.

Meanwhile, in the above, muscle mass and muscle quality were measured in the order of muscle mass measurement, performance capacity measurement, and muscle strength measurement.

When muscle mass, performance, and muscle strength are measured as described above, the measured muscle data is transmitted to the central server 500, and the central server 500 that has received the muscle data in this way stores the muscle data and calculates A muscle mass index, a performance capability index, and a muscle strength index are calculated from the muscle mass data, the physical activity performance data and the muscle strength data, respectively (S20).

Here, the central server 500, in order to calculate the muscle mass index, the performance index and the muscle strength index from the muscle data, respectively, the reference value of each of the muscle mass data, the physical activity performance data, and the muscle strength data according to the age and gender of the person to be measured set, and set each range value for each index with respect to the set reference value.

10 is a flowchart showing the detailed steps of such an index calculation. Referring to the drawing, the central server 500 first sets a reference value for index calculation (S41). These reference values can be set according to the age and sex of the person to be measured, and the reference values for each of the muscle mass data, the physical activity performance data, and the muscle strength data are set according to these standards.

When the reference value is set in this way, a range value for each index is set for the reference value ( S42 ). Here, the range value for each index may be set by dividing the range in stages based on the data determined to be sarcopenia.

When the daughter reference value and the range value for each index are set as described above, the central server 500 calculates each index by comparing it with the measured measurement data (S43).

That is, the measured muscle mass data, the physical activity performance data, and the muscle strength data are respectively compared with the range values to calculate the muscle mass index, the performance capacity index, and the muscle strength index, respectively.

At this time, the performance index is the physical ability value of the measurement target measured through the physical function test, the walking speed value measured when the measurement target person walks, and the exercise ability value measured through the exercise pattern and the amount of exercise during dynamic exercise, respectively. It can be calculated by conversion.

Table 1 shows an example in which the measured data is indexed according to the range value for each index of each item. Looking at this, the diagnostic criteria for sarcopenia for the measurement items are set based on the sarcopenia diagnostic criteria (reference value) and the range value for each index, and the sarcopenia calculation index for each item is compared with the measured data of each item and the corresponding range value for each index. to calculate In Table 1, the sarcopenia calculation index is configured in three stages of 0, 1, 2, but it is of course possible to design variously as an embodiment.

Table 1

When the range values for each index are set in this way, the central server 500 compares the measured muscle mass data, the physical activity performance data, and the muscle strength data, respectively, with the respective values and the range values, and corresponds to the corresponding range value, the muscle mass index, The performance index and muscle strength index are calculated respectively.

Here, the physical activity performance data includes the physical ability value of the subject to be measured measured through the simple physical function test, the walking speed value measured during walking of the subject to be measured, and the exercise ability measured through the exercise pattern and amount of exercise during dynamic exercise. It can be configured with a value.

On the other hand, the central server 500, to improve the accuracy of the muscle mass value measured by the muscle mass measurement module 120, an input layer consisting of bioimpedance values according to the frequency in the muscle mass measurement module 120, and the muscle mass measurement It is configured to be learned through a deep learning algorithm based on an output layer made of muscle mass values derived through means 150 and a deep neural network (DNN) based on a plurality of hidden layers, and the muscle mass measurement module ( 120) may be configured to verify the measured muscle mass value.

Furthermore, the central server 500 calculates the muscle mass per unit volume of the body part through the muscle mass of the body part measured through the muscle mass measurement module 120 and the volume value of the body part calculated by the volume measuring module 110 . It may consist of a bottom.

The central server 500 analyzes the calculated muscle mass index, performance index and muscle strength index, respectively, and determines whether sarcopenia is present (S30).

At this time, the central server 500, in order to determine the sarcopenia, sums the calculated muscle mass index, the performance index, and the muscle strength index, respectively, and determines whether sarcopenia through the summed index sum, and the sum is high It can be judged that the more you are exposed to the risk of sarcopenia.

On the other hand, for diagnosing sarcopenia, the content of the questionnaire as well as the muscle mass, muscle strength and physical ability including the aforementioned muscle thickness (circumference length) may be included as a diagnostic criterion for sarcopenia. In this case, the sarcopenia questionnaire can be applied to the Korean sarcopenia screening questionnaire (SARC-F), but is not limited thereto.

Meanwhile, the central server 500 stores each data including the muscle data and the sarcopenia analysis data analyzed in the above process, and transmits it to the mobile terminal 600 (S40).

Then, the mobile terminal 600, in conjunction with the central server 500, can read the muscle data and sarcopenia analysis data, and further can remotely manage the hardware measuring instrument 400 (S50).

Although the present invention has been described with reference to the embodiment shown in the drawings, which is merely exemplary, it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
