Description

DETAILED DESCRIPTION OF THE INVENTION BACKGROUND OF THE INVENTION The present invention relates to a device for measuring the motor function (motor ability) of a living body.

PRIOR ART In general, the range of fluctuations in the operating state of the circulatory system that occurs in response to exercise is larger in people with high circulatory function than in people with poor circulatory function. In addition, the changes over time show various types depending on the superiority or inferiority of the circulatory function. For this reason, for example, the pulse rate is measured before and after a certain exercise, immediately after a certain exercise, and after a certain period of time, and motor function is understood based on comparing these pulse rate changes with standard values. Ta.

Problems to be Solved by the Invention However, according to the conventional method of understanding motor function, the pulse rate is measured before and after exercise, immediately after exercise, and after a certain period of time has elapsed.
It is troublesome to use a table to select values indicating motor function corresponding to changes in pulse rate, and it is particularly difficult for inexperienced users to understand motor function by themselves.

First Means for Solving the Problems The present invention has been made against the background of the above circumstances, and its gist is to improve the motor function of a living organism by applying a constant exercise load to the living organism. A device for measuring: (1) an exertion intensity detection device that sequentially detects an amount representing the exertion intensity of the living body during exercise; and (2) an exercise intensity detection device for measuring the exertion intensity of the living body when the constant exercise load is applied. (3) storage means for storing in advance a standard curve representing a standard change in the amount representing the intensity over time; and (3) a time curve of the amount representing the exertion intensity detected by the exertion intensity detection device in the storage means. and display means for displaying the stored standard curve in a comparable manner.

Effects and Effects of the First Invention In this way, the display means can compare the time-lapse curve of the amount representing the exertion intensity detected by the exertion intensity detection device with the standard curve stored in the storage means. The current exercise ability of the living body can be easily understood by comparing the standard curve and the time course curve. That is, motor function can be understood very easily by looking at the degree of proximity between the above-mentioned time course curve and the standard curve.

In a preferred aspect of the present invention, the display means is configured to display, along with the time course curve, a time course curve of the amount representing the exertion intensity at the time of the previous motor function measurement. In such a case, there is an advantage that it is possible to easily recognize how much the motor function has improved compared to the previous time.

Further, in another preferred aspect of the present invention, the display means displays the time-course curve of the amount representing the exertion intensity while sequentially extending it every time the exertion intensity is detected by the exertion intensity detection device. It is composed of In such a case, since the time-lapse curve is displayed while being extended sequentially, it provides encouragement to the subject during exercise, and has the advantage that the pain caused by monotony can be alleviated.

Here, exertion intensity refers to the magnitude of the load on an individual living body (internal exercise load), and the amount that appears on the living body in response to the degree of exercise, such as the heart rate (pulse rate) of the living body. ), blood pressure value, PRP (product of heart rate and blood pressure value), etc. may be suitably used. Also,
The standard curve may be a single standard curve if the application of the device is limited, but if the device is used for an unspecified living body, a plurality of standard curves are stored in the storage means, and the age, sex, weight, and exercise of the living body are stored. It is selected as appropriate depending on the functional level.

Second Means for Solving the Problems Other aspects of the present invention are summarized as follows: (1) An exertion intensity detection device that sequentially detects an amount representing the exertion intensity of a living body during exercise of the living body. (2) a storage means for storing in advance a standard curve representing a standard change in the amount representing the exertion intensity of the living body over time when a constant exercise load is applied; and (3) the exertion intensity detecting device. The quantity representing the motor function of the living body is determined based on the correlation coefficient between the time-course curve of the quantity representing the detected exertion intensity and the standard curve stored in the storage means or the area value surrounded by the curve. The present invention includes a motor function determining means, and (4) a display means for displaying a quantity representing the motor function of the living body determined by the motor function determining means.

Effects and effects of the second invention In this way, the motor function determining means can compare the time-course curve of the amount representing the exertion intensity detected by the exertion intensity detection device with the standard curve stored in the storage means. The amount representing the motor function of the living body is determined based on the correlation coefficient or the area value surrounded by the curve, and the amount representing the motor function of the living body is displayed on the display means. Therefore, the motor function of the living body can be measured very easily by looking at the amount representing the motor function of the living body displayed on the display means.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

In FIG. 1, reference numeral 10 is an ergometer that applies an exercise load to the subject by making him/her exercise, and the load is adjusted by a microcomputer 12. A signal representing the rotation of the ergometer 10 is transmitted from the rotation sensor to the microcomputer 12.

The pulse sensor 14 constitutes the exertion intensity detection device of this embodiment and detects the pulse of the subject. We are prepared. The optical sensor detects a change in blood volume in the earlobe, that is, the pulse, and a pulse signal SM representing the pulse is supplied to the I/O port 16 of the microcomputer 12.

A memory card 18 owned by each person to be measured stores name, age, gender, weight, motor function level, previously measured motor function data, measurement date and time, and the like. Card reader 20 is memory card 1
When the memory card 18 is inserted into the card reader 20, a signal indicating the start of motor function measurement is output, and the information stored in the memory card 18 is transmitted to the microcomputer 12. It is becoming more and more common.
The clock circuit 22 also transmits time data representing the current date and time to the microcomputer 12.

The microcomputer 12 has a CPU 24 and a ROM 2 connected to each other by a data bus line.
6. Equipped with 28 RAM. The CPU 24 is
ROM2 while using the primary storage function of RAM28
The input signal is processed according to a program stored in advance in the ergometer 6, and the load (rotational resistance) of the ergometer 10 is controlled, and the detected exertion intensity is displayed on the display 30, which is the display means of this embodiment. A time course curve 32 of the indicated value is displayed together with a standard curve 34 and a previous time course curve 36 stored in advance in the ROM 26, and at the same time, a separately calculated value representing motor function (motor ability) is displayed.

As shown in FIG. 2, the display 30 is a cathode ray tube or LCD that can display images using a large number of display elements.
The device is equipped with an image display device such as the above, and the display screen 38 is disposed at a position where it can be easily seen by the person being measured. In the orthogonal coordinates on the display screen 38, including the time axis 40 and the axis 42 indicating the value representing the exertion intensity (in this example, pulse rate), the curve 3
2, 34, and 36 are displayed so that they can be compared, and a separately calculated value representing the motor function is displayed at the display location 46 in the upper right corner of the display screen 38.
A display 30 is configured. However, display 3
0 may employ another display mechanism such as a plotter or dot printer.

The operation of this embodiment will be explained below with reference to the flowchart of FIG.

First, in step S1, the memory card 18
It is determined whether the card is attached to the card reader 20 or not, and if it is not attached, the execution of step S1 is repeated. When the memory card 18 is inserted, step S2 is executed and the memory card 1 is inserted.
As the information stored in 8 is read,
Step S3 is executed, and a plurality of standard curves 34 previously stored in the ROM 26 are selectively selected according to the age, sex, weight, and motor function level of the subject stored in the memory card 18; the standard curve 34 selected after step S4 is executed;
and the time course curve 36 measured last time and stored in the memory card 18 on the display screen 3 of the display 30.
8. This standard curve 34 is a standard curve determined according to the subject's age, sex, weight, and motor function level.

Then, by executing the subsequent step S5, a message to the subject, for example, "Please rotate the ergometer until the end instruction is given" is displayed in the voice or on the display screen 38. In the following step S6, it is determined whether or not the subject has started rotating the ergometer 10 according to this rotation instruction. If the subject has not started rotating the ergometer 10, step S6 is repeatedly executed. When it is determined that rotation has started, steps S7, 8, and 9 for controlling the load on the ergometer 10 are executed. That is, by executing step S7, the ergometer 1 is
The load of 0 is considered as no load, and by executing step S8, the load of the ergometer 10 is increased in a certain load period B according to a preset load curve, for example, the PWC (Astrand) method, and further , step S9 is executed, the load on the ergometer 10 is made to be unloaded during the fixed end period C. As the load curve for the load period B, one selected corresponding to the standard curve 34 is used.

In the process of executing steps S7, S8, and S9, execution of the interrupt routine shown in FIG. 4 is permitted each time the pulse signal SM is supplied to the I/O port 16. In this interrupt routine, the pulse cycle is detected by executing step SW1, and the pulse rate (instantaneous value) is determined based on the pulse cycle. Further, by executing step SW2, the determined pulse rate is stored in the RAM 28 and the memory card 18 together with time data representing the elapsed time from the start of measurement or the current time, and at the same time, the determined pulse rate is displayed on the display 30. It is plotted on the display screen 38. Therefore, by repeatedly executing this interrupt routine, the pulse rate is successively determined, and the display screen 38 displays the following information:
Due to the application of the exercise load, a time-lapse curve 32 representing the reaction of the subject and representing the actual exertion intensity is displayed while being expanded. Figure 2 shows steps S7, 8,
This shows the display state when the execution of step 9 is completed.

When step S10 following step S9 is executed, a message such as "Please stop rotating the ergometer" is displayed in the voice or on the display screen 38. Therefore, in accordance with the stop instruction, the person being measured uses the ergometer 10.
stop rotating.

Next, by executing step S11, the area value of the portion 44 surrounded by the temporal curve 32 and the standard curve 34 is calculated by the integrating means or both curves 32.
and 34, and a value representing the motor function is determined from the area value in step S12, followed by step S13.
The value is displayed at a display location 46 provided at the upper right of the display screen 38 as, for example, "I-86". The "I" indicates the motor function level, and "86"
indicates the athletic ability in that class, but the athletic ability may be displayed in a single class.

In this way, according to this embodiment, the time course curve 32 that represents the actual exertion intensity (internal load) over time, which is the reaction that occurs in the subject when a certain external exercise load is applied, is common. Time axis 4 is the display location of
0 and the axis 42, it is displayed so that it can be compared with the standard curve 34, which is the standard for the motor function level to which the subject belongs, so that the standard curve 34 can be compared by comparing the two. motor function can be relatively understood and measured.

Furthermore, according to this embodiment, the previously measured time course curve 36 is also displayed at the common display location, so that
By comparing with the time course curve 32 measured this time, there is an advantage that changes in motor function can be easily grasped.

Further, according to this embodiment, since the time course curve 32 gradually expands during the exercise process of the subject, this provides encouragement to the subject and has the advantage of alleviating pain caused by monotony.

Furthermore, according to this embodiment, the time course curve 32
Since the amount representing the motor function of the subject determined based on the area value of the portion 44 surrounded by the standard curve 34 is displayed at the display location 46, the motor function of the test subject is automatically It also has the advantage of being quantitatively measured.

Next, another embodiment of the present invention will be described.

The value representing the motor function of the example is a portion 44 surrounded by the time course curve 32 and the standard curve 34.
It is determined based on the area of time curve 3.
2 and the standard curve 34. That is, the more similar the temporal curve 32 and the coordinate curve 34 are, the closer the athletic ability is to the standard value. For example, the steps shown in FIG.
SS11 and SS12 are configured to be executed in place of steps S11 and 12 in FIG. Therefore, in step SS11, standard curve 3
4 and the time course curve 32 is calculated using a well-known method, and in step SS12,
Based on the correlation coefficient, a value representing motor function is determined. That is, the larger the correlation coefficient, the higher the motor function. Then, when the subsequent step S13 is executed, the value thus determined is displayed at the display location 46.

Although one embodiment of the present invention has been described above, the present invention is also applicable to other aspects.

For example, in the above embodiment, the pulse rate was used as the quantity representing the actual exercise load of the subject, but instead, heart rate, blood pressure value, PRP (product of heart rate and blood pressure value), etc. may be used. It's okay. This is because these amounts correspond to myocardial oxygen consumption, which reflects the exertion intensity of the living body. In such a case, the axis 42 may be used to record heart rate, blood pressure,
It is an axis that indicates one of PRP, etc., and it is necessary to provide a heart rate sensor, a blood pressure measuring device, or a PRP calculation means.

Furthermore, the amount representing the motor function of the subject determined in step SW2 may be the area value as it is, or may be classified into simple numbers or levels, or may be converted into its reciprocal. etc. may be used.

Furthermore, in the embodiment shown in FIGS. 1 and 3,
While the motor function can be grasped and measured relative to the standard curve 34 by comparing the time course curve 32 and the coordinate curve 34 within the orthogonal coordinates having the time axis 40 and the axis 42 that are a common display location, The amount representing the motor function of the subject determined based on the area value of the portion 44 surrounded by the temporal curve 32 and the standard curve 34 is displayed at the display location 46, and the motor function of the test subject is displayed. are now being measured automatically and quantitatively, but a subject's motor function can be measured using either one of them. In such a case, the time course curve 32 and the standard curve 34 are displayed on the display 30 so that they can be compared, or the amount representing the motor function of the subject determined based on the area value is simply displayed. Is displayed.

Further, the temporal curve 32 and the like can be displayed in various forms such as a step graph, a line graph, a bar graph, etc. in a two-dimensional or three-dimensional manner. In short, any display mode that allows the temporal curve 32 to appear is sufficient.

Also, instead of the ergometer 10, other exercise equipment, such as a step or a treadmill, can be used. In the case of a treadmill, a certain exercise load can be applied according to the Bulk method, Robinson method, Bruce method, etc.

Furthermore, a keyboard may be provided in place of the card reader 20, and various data may be entered by operating the keyboard.

The above-mentioned embodiment is merely one embodiment of the present invention, and various modifications may be made to the present invention without departing from the spirit thereof.
