Description

  The present invention relates to a health measuring device that measures health indices related to exercise ability such as muscle strength, flexibility, and balance sensation by measuring body sway.

  Traditionally, center-of-gravity sway meters that measure body sway are known for a long time and used in the field of dizziness / equilibrium function diagnosis or rehabilitation medicine / sports medicine, etc. Upset is used as an index.

  The user of the center of gravity shake meter puts both feet on a predetermined position on the platform and holds various measurement postures for a predetermined time. The measurement posture includes standing on both feet, standing on one foot, or a posture in which the body is tilted so as to move the center of gravity of the body in the front-rear direction and the left-right direction as much as possible. The center of gravity shake meter calculates the above-described center of gravity shake parameter from the locus of the center of gravity position in each posture, and determines whether the user is healthy based on the calculated value. The center-of-gravity shake meter displays the judgment result, the locus of the center of gravity, or the center-of-gravity shake parameter.

  The balance of the center of gravity is kept stable by continuous minute movements between the trunks composed of the head, trunk, and limbs. Such a function of maintaining the balance of the center of gravity involves various biological functions such as brain balance sense function, muscle strength, joint flexibility, sole sense, and visual information processing function. In particular, the strength of the lower limbs and the flexibility of the ankle joint are considered important for maintaining the balance of the center of gravity. For this reason, it has been proposed to use the center of gravity fluctuation for simple evaluation of motor functions such as muscle strength and flexibility.

For example, Patent Document 1 discloses an apparatus for evaluating athletic ability by displaying both the current center-of-gravity position of a subject and a target center-of-gravity position, and measuring the time until the subject actually moves the center of gravity. Proposed. Further, Patent Document 2 proposes an apparatus for measuring a health index by detecting a load fluctuation applied to a platform of a weight scale and measuring a center of gravity fluctuation based on the result. Patent Document 3 proposes a method for evaluating an ankle function from the position of the center of gravity of a subject when tilting.

The amount of exercise in regular physical exercise is the amount of exercise by the user, and is expressed by the amount of displacement of the center of gravity and the number of exercises during exercise, and the acceleration sensor 13 measures the number of exercises. Since the acceleration sensor 13 moves while being gripped by the user, the acceleration sensor 13 outputs a voltage signal having a substantially constant cycle as a measurement value by moving up and down with regular physical movement of the user. .

Next, the electrical configuration of the health measuring device 1 will be described.
As shown in FIG. 6, the health measuring device 1 includes a CPU 14, and an input unit 15, a ROM 16, a RAM 17, a display screen 8, and a speaker 12 as a notification unit are connected to the CPU 14. The input unit 15 includes the mode selection switch 9, the setting button 10, and the exercise measurement start / end button 11 described above.

  The CPU 14 performs predetermined processing on data input from various input means of the operation unit 5 and performs arithmetic processing according to a program stored in the ROM 16, causes the display screen 8 and the speaker 12 to output data, and the RAM 17. Save the data.

  Specifically, the CPU 14 measures the exercise performed by the user when the user presses the exercise measurement start / end button 11 in a state where the input by the mode selection switch 9 and the setting button 10 is completed and the exercise can be started. To start.

  When the motion measurement start / end button 11 is pressed, the CPU 14 inputs data from each of the load cells 4, amplifies and amplifies those signals after noise reduction. Then, the fluctuation of the added value is detected, and it is determined whether or not the fluctuation value is within a predetermined range. If the added value is within the predetermined range, the CPU 14 determines that the center of gravity of the user on the platform 2 is stable, and displays on the display screen 8 contents instructing the user to perform regular physical exercise. Let

  Then, as shown in FIG. 7, the CPU 14 displays a sentence “please bend and stretch the knee 10 times in accordance with the blinking of the lamp” on the sentence display portion 8 a of the display screen 8, and also on the display screen 8. By displaying the lamps 18 and 19 that alternately blink in accordance with the knee bending and stretching pitch, the user is instructed to perform regular physical exercise. The CPU 14 turns on the lamp 18 when the user bends the knee, and turns on the lamp 19 when the user stretches the knee. The pitch interval of the exercise is set to 1 second interval, for example. The CPU 14 blinks the lamps 18 and 19 in accordance with the pitch of the exercise, and generates an electronic sound from the speaker 12 in accordance with the pitch.

  In addition, when the type of exercise selected by the mode selection switch 9 is the raising / lowering of the heel, the CPU 14 displays “increase / lower the heel 10 times according to the blinking of the lamp” in the sentence display portion 8a of the display screen 8. "Is displayed. Further, when the exercise type selected by the mode selection switch 9 is the toe raising / lowering, the CPU 14 displays “toe raising / lowering the toe in accordance with the blinking of the lamp” in the sentence display portion 8a of the display screen 8. "Please go once."

  Further, the CPU 14 functions as a center-of-gravity detection unit that detects the position of the center of gravity of the user based on the load of the user detected by the load cell 4. When the user starts exercising, the CPU 14 detects the position of the center of gravity of the user based on the load value of the load cell 4 AD-converted at a predetermined sampling frequency, for example, 20 Hz, and temporarily stores the data in the RAM 17.

  Then, as shown in FIG. 8A, the CPU 14 displays the XY coordinate screen 8b on the display screen 8 as a display means to display the position of the center of gravity of the user under measurement. When the user starts exercising, the screen is switched to the screen shown in FIG. 8A, and the positions of the lamps 18 and 19 are moved and displayed in the display screen 8. Further, as shown in FIG. 8B, the CPU 14 can also display the locus of the center of gravity position that varies during the measurement on the XY coordinate screen 8b.

  Then, the CPU 14 measures the user's center-of-gravity displacement amount as the amount of exercise in regular physical exercise based on the center-of-gravity position, and stores the result in the RAM 17. The center-of-gravity displacement is expressed as a ratio of the center of gravity moving from the user's heel to toe with regular physical movement. The momentum (center-of-gravity displacement) is stored in the RAM 17 and the data is accumulated, so that the evaluation of the center-of-gravity fluctuation parameter can be standardized.

  Further, the CPU 14 functions as an exercise amount measuring means for measuring the amount of exercise (number of exercises) of the user's regular physical exercise. When the CPU 14 receives a voltage signal from the acceleration sensor 13 as the user moves, the CPU 14 converts the voltage signal into a pulse signal and counts the number of pulses by the counter circuit. Then, the CPU 14 displays the count value on the display screen 8 as the current number of exercises as shown in FIG. Then, the CPU 14 determines whether or not the amount of exercise (number of exercises) of the user's regular physical exercise has reached a predetermined amount, which is 10 times in this embodiment, and determines that the number of exercises has reached 10 times. Then, the user is notified of the end of the exercise by generating an electronic sound indicating the end of the exercise from the speaker 12.

  Moreover, CPU14 functions as an evaluation means which evaluates a user's motor function based on the gravity center position which self calculated. CPU14 reads the data of the gravity center position memorize | stored in RAM17, and calculates the level of the strength of a leg, for example as a user's exercise | movement function based on the data.

  Further, the CPU 14 stores the strength level (motor function) of the legs and hips in the RAM 17 in association with the user data (the user's age, sex, height, and length from the toe to the toe). If it does so, CPU14 as a setting means will be able to set the kind of regular physical exercise based on the history of the exercise function memorized by RAM17, if user data is inputted from input part 15. .

  In addition, when the user performs regular physical exercise a predetermined number of times, 10 times in the present embodiment, and when the exercise measurement start / end button 11 is pressed again, the CPU 14 stops the exercise measurement and exercises the exercise. The function evaluation result is displayed on the display screen 8. For example, as shown in FIG. 10, the CPU 14 causes the text display unit 8 a of the display screen 8 to display a text with a content such as “Your leg / level is 4”.

Next, processing executed by the CPU 14 of this embodiment will be described with reference to FIG.
As shown in FIG. 11, first, when the power switch 6 is turned on in step S1, the health measuring device 1 is activated. In this state, the user holds the operation unit 5 with both hands, and puts both feet on the upper surface 2 a of the step 2 in accordance with the foot position guide 3 on the step 2.

  Then, after the user's age, sex, height, and foot length are input in step S2, the CPU 14 starts measuring the movement when the movement measurement start / end button 11 is pressed in step S3.

  First, the CPU 14 performs load addition processing based on the data input from each load cell 4 in step S4, measures the load variation, and then proceeds to step S5 to determine whether the load variation is within a predetermined range. To do. If it is determined that the load fluctuation is not within the predetermined range (step S5, NO), the process returns to step S4 to measure the load fluctuation.

  If it is determined that the load fluctuation is within the predetermined range (step S5, YES), the CPU 14 proceeds to step S6, and displays the contents of regular physical exercise on the display screen 8. In the present embodiment, a sentence “Please do knee bending and stretching 10 times according to the blinking of the lamp” is displayed on the sentence display portion 8 a of the display screen 8. Then, the CPU 14 proceeds to step S7 and starts blinking the lamps 18 and 19 in accordance with the pitch interval of the movement, and proceeds to step S8 to start generating pitch sound from the speaker 12 in accordance with the pitch interval of the movement.

  Then, after measuring the center of gravity position in step S9, the CPU 14 proceeds to step S10 and stores the data of the center of gravity position in the RAM 17. Then, the CPU 14 proceeds to step S11 and determines whether or not the number of exercises by the user has reached a predetermined number. If it is determined that the predetermined number of times has not been completed (step S11, NO), the process returns to step S9 to measure the center of gravity position.

  If the CPU 14 determines that the number of exercises by the user has been completed a predetermined number of times (step S11, YES), the CPU 14 proceeds to step S12, and the center of gravity position is determined by pressing the exercise measurement start / end button 11 by the user. End the measurement. Then, the CPU 14 proceeds to step S13 to end the blinking of the lamps 18 and 19, and proceeds to step S14 to end the generation of the pitch sound from the speaker 12. Then, the CPU 14 proceeds to step S15 to perform arithmetic processing based on the data of the center of gravity stored in the RAM 17, and proceeds to step S16 to display the user's motor function level calculated as a result on the display screen 8, This process ends.

Here, the determination method for determining the level of the strength of the legs performed by the CPU 14 will be described.
FIG. 12 shows the variation of the center-of-gravity position in the front-rear direction normalized by the length to the toe of the foot as a heel and a reference when the knee is bent and stretched five times. If the center of gravity is on the toe, it is 0%, and if there is a center of gravity on the toes, it is 100%. As shown in FIG. 12, the position of the center of gravity in the front-rear direction changes between the posture in which the knee is bent and the posture in which the knee is extended.

  In general, when the knee is bent, the center of gravity moves forward compared to the stretched state. At this time, when the muscle strength of the lower limbs is strong and flexible, that is, when the legs and hips are stable, the position of the center of gravity does not change greatly. For this reason, in this embodiment, the difference between the maximum value of the center of gravity position when the knee is bent and the minimum value of the center of gravity position when the knee is extended is calculated as the displacement amount M of the center of gravity position, and a plurality of displacement amounts are calculated. Based on the maximum value of M, the level of the strength of the legs is determined.

  Specifically, the CPU 14 is level 1 when the displacement M of the center of gravity during bending and stretching of the knee is 50% or more, level 2 when 40% to 50%, and when 30% to 40%. Level 3 is judged as level 4 when 20% to 30%, and level 5 when less than 20%. In other words, the higher the level, the stronger the legs.

  In the example shown in FIG. 12, since the maximum value of the measured value is 25% of the displacement amount M5 among the displacement amounts M1 to M5 of the center of gravity position when the knee is bent and when the knee is extended thereafter, the CPU 14 Determined the leg strength level to be 4.

  The CPU 14 stores the determined strength (motor function) of the legs and feet in the RAM 17 in association with user data, in this embodiment, the age, sex, height, and length of the foot from the toe to the toe. Then, when the same data is input from the input unit 15 by the user, the CPU 14 can read the strength level of the legs from the RAM 17 in association with the data.

  Further, the CPU 14 can set a regular type of physical exercise corresponding to the strength level of the legs and hips. For example, if a correspondence table indicating the correlation between the level of the strength of the legs and the legs and the content of regular physical exercise is stored in advance in the RAM 17 based on the past history, the CPU 14 refers to the correspondence table. And set up regular physical exercise. For example, the CPU 14 can change the pitch interval of the exercise corresponding to the level of strength of the legs. In this embodiment, the motion pitch interval is set to 1 second, for example, in the initial setting.

  Further, for example, when the strength level of a specific user's legs is level 5 continuously for a predetermined number of times or more, the CPU 14 shortens the pitch interval of the exercise to be shorter than 1 second, for example, 0.5 seconds. Set. Then, the CPU 14 performs a five-step evaluation based on the maximum displacement amount of the center of gravity position in the movement with a pitch interval of 0.5 seconds. Here, when the displacement amount of the center of gravity during bending and stretching of the knee is 50% or more, it is level 6, when it is 40% to 50%, it is level 7, when it is 30% to 40%, it is level 8, 20% to When it is 30%, it is judged as level 9, and when it is less than 20%, it is judged as level 10.

Next, characteristic effects of the present embodiment will be described.
(1) In the health measuring apparatus 1, regular physical exercise is instructed to the user by the display screen 8, the center of gravity of the user is detected based on the load detected along with the exercise, and the displacement of the center of gravity is detected. The level of strength (motor function) of the user's legs is evaluated based on the amount. For this reason, if the user can perform a regular physical exercise in a stable state on the platform 2 and the movement of the center of gravity is likely to occur, the strength of the legs and hips can be determined based on the fluctuation of the center of gravity of the user. The level (motor function) can be objectively evaluated more accurately.

  (2) Since the user can select a regular physical exercise type (exercise type) with the mode selection switch 9 in the health measuring apparatus 1, the exercise type should be set according to the purpose. Can do.

  (3) Since the center of gravity position of the user being measured is displayed on the health measuring device 1, the user can exercise while checking his / her center of gravity position. For this reason, the user can exercise within the set range, and data with higher objectivity and less individual differences can be obtained.

  (4) The health measuring device 1 measures the center-of-gravity displacement amount (exercise amount) of the user's regular body movement, and the result is stored in the RAM 17. For this reason, it becomes possible to obtain more accurate data by standardizing the evaluation of the center-of-gravity fluctuation parameter based on the history of momentum.

  (5) In the health measuring apparatus 1, since the user is notified whether or not the number of exercises (exercise amount) has reached a predetermined amount, the user can exercise while checking his / her center of gravity position. For this reason, the user can exercise within the set range, and data with higher objectivity and less individual differences can be obtained.

  (6) The health measuring device 1 stores the level of strength (motor function) of the user's legs in association with the user's data, and when the user's data is input to the input unit 15, the regularity It is also possible to set a certain type of physical exercise. For this reason, it is possible to automatically set a regular physical exercise suitable for the user simply by inputting the user's data to the input unit 15.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In addition, about the same component, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

The health measurement device of the present embodiment is different in configuration from the health measurement device 1 of the first embodiment in that a pair of electrodes is provided.
As shown in FIGS. 13 (a) and 13 (b), the health measuring device 20 of the present embodiment is provided at the position of the application electrode 21 provided at the position of the toe guide 3a of the step 2 and the position of the heel guide 3b.

  As shown in FIG. 14, the application electrode 21 and the measurement electrode 22 are connected to a constant current circuit built in the CPU 14. When the CPU 14 outputs a weak high frequency current to the constant current circuit, a current is applied to the soles of the user's feet via the application electrode 21, and a potential difference between the feet is detected by the measurement electrode 22. The CPU 14 calculates the user's bioimpedance based on the voltage blood value detected by the measurement electrode 22, and calculates (estimates) the muscle mass of both legs as the body composition component of the user based on the bioimpedance.

  And CPU14 as a determination means determines a user's life activity function based on the estimated amount of muscle mass of both legs, and the level (motor function) of the strength of a leg. In the present embodiment, as the user's life activity function, the muscle activity level is calculated by dividing the level of strength of the legs and legs by the muscle mass. As shown in FIG. 15, the CPU 14 displays a sentence such as “Your muscle activity level is 4” on the display screen 8 with the calculated muscle activity level. The smaller the muscle activity level, the smaller the motor function for the muscle, so it can be seen that the motor function level can be improved. It means that it is necessary to strengthen muscles because it means that the motor function is large.

  The CPU 14 after step S5 in FIG. 11, that is, after determining that the weight fluctuation of the user on the platform 2 is within a predetermined range, before displaying the content instructing the user to exercise in step S6, Calculation of muscle mass and determination of muscle activity level.

Next, characteristic effects of the present embodiment will be described.

You can know the correlation with the level. For this reason, the user can examine, for example, whether to increase muscles or improve the strength of the legs.

In addition, you may change embodiment of this invention as follows.
In each of the above embodiments, the acceleration sensor 13 for measuring the number of exercises is provided as the momentum measuring means, but as shown in FIG. 16, the movement distance associated with the exercise is measured at the lower end of the operation unit 5 as the momentum measuring means. A laser displacement meter 23 may be provided. The laser displacement meter 23 detects the distance L between the lower end of the operation unit 5 and the upper surface 2a of the step platform 2 and outputs it to the CPU 14 while being held by the user. The CPU 14 inputs, from the laser displacement meter 23, the distance L1 when the knee is stretched as shown in FIG. 17A and the distance L2 when the knee is bent as shown in FIG. . Then, the difference distance L3 = L1-L2 is calculated, and the level of bending and stretching is determined from the value of the distance L3.

  Then, the CPU 14 determines whether or not the distance L3 is within an appropriate range set in advance, and notifies the user of the result. If the distance L3 is less than the appropriate range, the CPU 14 turns on yellow on the display screen 8, turns on blue if the distance L3 is within the appropriate range, and turns red on if the distance L3 is greater than the appropriate range. For this reason, the user can exercise while confirming an appropriate range of the amount of knee bending and stretching, and data with higher objectivity and less individual differences can be obtained.

  In each of the above-described embodiments, the weight may be calculated from the load cell and the total load, and the health condition may be managed by combining the motor function and the weight due to the change in the center of gravity. Moreover, you may determine a motor function using the variation | change_quantity of a body weight instead of the displacement amount to center of gravity.

  In each of the above embodiments, the acceleration sensor 13 for measuring the number of exercises is provided as the amount of exercise measuring means. Instead of measuring the number of exercises as the amount of exercise with the acceleration sensor 13, between the step platform 2 and the operation unit 5. By utilizing the restoring force to wind the reel of the connection cable 7 and measuring the expansion / contraction amount of the connection cable 7 with a digital scale, the number of movements and the movement distance due to bending and stretching of the knee may be detected.

  In each of the above embodiments, the case where the pitch interval of the regular exercise is set to 1 second has been described, but the user may set the pitch interval of the exercise. In this case, for example, the user may operate the setting button 10 to display the pitch sound interval mode in the setting menu on the display screen 8 and select, for example, 1 second or 0.5 second as the pitch interval. Further, although the case where the number of regular physical exercises is set to 10 has been described, the user may set the number of exercises, and the number may be selected similarly to the pitch interval of the exercise.

  In each of the above embodiments, regular physical exercise is performed at a predetermined pitch interval, but it is not always necessary to perform exercise at regular intervals. In that case, the pitch interval of regular physical exercise may be set as indefinite.

  In each of the above embodiments, three types of exercise in regular physical exercise are set, but the number of types of exercise may be two or less, or may be four or more. Moreover, the kind of exercise | movement is not limited to what was demonstrated by said each embodiment.

  In each of the above-described embodiments, the method of determining the strength of the legs and hips based on the displacement amounts M1 to M5 of the center of gravity has been described. However, other methods may be used based on various feature amounts using the center of gravity movement curve. For example, the standard deviation of the center-of-gravity displacements M1 to M5 may be obtained, and the strength of the legs and hips may be determined based on the standard deviation. Alternatively, the strength of the legs may be determined using the time from the rise of the center of gravity movement curve to the peak, the timing of the pitch sound and the time until the rise of the center of gravity movement curve as feature amounts.

  In each of the above embodiments, the connection cable 7 is provided between the step 2 and the operation unit 5. However, a communication means is provided for each of the step 2 and the operation unit 5, and signals are transmitted wirelessly using radio waves, light, or the like. You may send and receive.

In each of the above embodiments, the position of the center of gravity being measured is displayed on the display screen 8, but the position of the center of gravity being measured need not necessarily be displayed.
In each of the above embodiments, the CPU 14 stores the user data input from the input unit 15 and the calculated data of the center of gravity position in the RAM 17, but it is not always necessary to store these data.

  In the second embodiment, the CPU 14 estimates the muscle mass based on the bioimpedance of the user, but estimates the body fat mass, internal fat area, water content, bone mass, etc. based on the bioimpedance, and The user's life activity function may be determined by combining the body composition component and the motor function.
