In general, since the left and right arm lengths or body skeletons of a subject may be different from each other, it is necessary to adjust the arm lengths or body skeletons on both sides within a certain range in order to perform a test to be described later.

In addition, even in the case of a posture in which the subject stands, it may be inclined forward or backward, and the degree of inclination needs to be adjusted within a certain range.

Accordingly, it is necessary to adjust the posture of the subject within a predetermined range in which an examination to be described later can be performed through the posture adjusting unit 300 .

Meanwhile, as described above, information about the measured plantar pressure and the load is provided to the calculating unit 400 .

On the other hand, the monitoring unit 700 monitors all the body posture measurement states performed through the body posture measurement system 10, and, if necessary, displays the monitored information to the examinee and the operator through the display unit. .

The calculation unit 400 performs a predetermined operation based on the plantar pressure measurement information provided from the first pressure measurement unit 510 and the load measurement information provided from the second pressure measurement unit 520 , , calculates the balance score in each posture of the examinee, and provides the calculated balance score to the control determination unit 600 .

Meanwhile, details of the calculation process of the balance score in the calculation unit 400 will be described in detail in the description of the posture measurement method below.

3 is a flowchart illustrating a body posture measurement method using the body posture measurement system of FIG. 1 .

Referring to FIG. 3 , in the body posture measuring method using the body posture measuring method 10 , first, body information of a subject is input through the information input unit 100 (step S10 ).

In this case, the inputted body information is the same as described above, and the body information of the examinee may be directly input through a separate terminal, or the body information may be input through identification of the examinee.

Thereafter, when the subject stands on the plate unit 11 , the position measuring unit 200 measures the position at which the subject stands on the plate unit 11 (step S20 ).

On the other hand, the subject holds the left and right support frames 20 and 30 while standing on the plate part 11, and as described above, depending on the body structure or posture of the subject, the subject holds it on both sides. The location may be different.

Accordingly, the posture adjusting unit 300 adjusts the posture of the subject based on the standing position of the subject and the position of the subject holding the support frame (step S30).

In this case, a specific method of adjusting the posture of the posture adjusting unit 300 is the same as described above.

After that, the test, that is, the body posture of the subject is measured based on the pressure measurement through the pressure measuring unit 500 (step S40).

On the other hand, the measurement state of the subject's body posture or the measurement result of the body posture is monitored through the monitoring unit 700 and, if necessary, is displayed externally (step S50), and based on the measurement result, the control determination unit ( 600) determines whether there is an abnormality in the subject (step S60).

Hereinafter, the measuring step (step S40) of the subject's body posture will be described in detail with reference to FIGS. 4 and 5 .

FIG. 4 is a flowchart illustrating a detailed method of the inspection performing step of FIG. 3 , and FIG. 5 is a flowchart illustrating the equilibrium score calculation step of FIG. 4 . 6A is a schematic diagram illustrating a state in which the subject stands upright in the body posture measurement system of FIG. 1 , and FIG. 6B is a schematic diagram illustrating a state in which the subject is inclined.

4 and 5 , in measuring the body posture of the subject, first, the plantar pressure of the subject is measured by the first pressure measuring unit 510 on the plate part 11 positioned on the upper part of the subject. do (step S41).

In addition, the load applied to the second pressure measuring unit 520 on the support frames 20 and 30 held and supported by the examinee is measured (step S42).

Thereafter, based on the plantar pressure measured by the first pressure measuring unit 510 and the load measured by the second pressure measuring unit 520 , the balance score of the examinee is calculated (step S43 ).

In this case, in order to calculate the balance score of the examinee, it is necessary to calculate the balance score in each posture while the subject is positioned in six suggested postures. Each posture of the examinee for calculating the balance score of the subject This will be described later with reference to FIG. 7 .

In the present embodiment, the calculation unit 400 is characterized in that the balance score is calculated based on the plantar pressure information and the load information. A more specific calculation method of the balance score is as follows.

Accordingly, with additional reference to FIGS. 6A and 6B , in the calculating unit 400, after deriving the subject's inclination angle (step S45), the maximum value (θ _max ) and the minimum value of the derived inclination angle (θ) Based on (θ _min ), an equilibrium score is calculated (step S46).

6A and 6B show only the upper frames 23 and 33 of the left and right support frames 20 and 30 for convenience of explanation, and the arm of the subject holding the upper frames 22 and 23 has been omitted.

In this case, in the step of deriving the inclination angle θ, the calculating unit 400 calculates a center of pressure (COP) by the plantar pressure based on the measured plantar pressure, and the Based on the measured load, the center of pressure by the load is calculated.

Thereafter, the calculating unit 400 derives the inclination angle of the body of the examinee based on the center of pressure due to the plantar pressure, the center of pressure due to the rod, and the center of the foot of the examinee.

In this case, the center of pressure (COP) is defined as an action point of the corresponding force when it is assumed that the pressure distributed over a predetermined area acts intensively on one point.

Therefore, the center of pressure by the plantar pressure can be said to be the point of application of the corresponding force when it is assumed that the distribution of the plantar pressure acts on one point, and the center of pressure by the rod is supported by the examinee When it is assumed that the distribution of two different loads of the left and right support frames acts on one point, it can be said to be the point of action of the corresponding load.

On the other hand, the center of foot refers to the center of foot support in a state where the subject is supported by the foot and stands normally. When considering the overall standing state without considering the pressure actually applied to the foot, It can be said to mean the center of foot support.

More specifically, referring to FIG. 6A , in a state in which the subject 1 stands in an upright posture, the center of the foot of the subject corresponds to the center of the overall standing state, and the subject 1 stands in an upright posture. In one state, the pressure is concentrated on the rear side of the foot, so the center of pressure (COP) due to plantar pressure is located on the heel side as shown.

In this case, in the case of the center of the foot, it is generally located in front of the ankle of the subject's foot and is located on the front side, which is about 14% from the front of the entire foot.

In addition, in a state in which the subject 1 stands in an upright posture, the center of gravity (COG) of the subject 1 is known to be located at a height of 0.35 to 0.7 times the height of the subject 1, e.g. For example, it may be located at a height of 0.55 times.

는 피검자의 키(height)를 의미한다. As such, assuming that the center of gravity of the examinee is located at a height of 0.55 times the height of the examinee, the height H to the center of gravity of the examinee 1 may be defined by the following formula (1). in this case,

is the height of the subject.

식 (1)

Equation (1)

In this case, the position of the center of gravity (COG) of the subject 1 is, after all, the center of pressure (COP) by the rod, that is, the point of action of the rod when it is assumed that the distribution of two different rods acts at one point. will correspond to the position of That is, if the center of pressure (COP) is derived based on the rods measured through the two different left and right second pressure measuring units 521 and 522, the position of the subject's center of gravity can be derived. .

On the other hand, referring to FIG. 6B , when the subject 1 is tilted and changed to a predetermined position for the examination of the balance function, the calculation unit 400 ultimately determines the inclination angle θ according to the change in the posture. It can be derived through the following formula (2).

식 (2)

Equation (2)

In this case, the inclination angle θ in Equation (2) is defined to subtract 2.3 because, in general, the position of the center of gravity (COG) is inclined forward by 2.3 degrees when the subject stands normally, which is It may be defined differently depending on the tilted state of the subject.

Furthermore, the calculation unit 400 may finally calculate a balance score by the following equation (3) based on the calculation result of the inclination angle θ.

식 (3)

Equation (3)

In this case, θ _max means the maximum value of the inclination angle θ, and θ _min means the minimum value of the inclination angle θ.

On the other hand, in the above formula (2), P is defined by the following formula (4).

식 (4)

Equation (4)

In Equation (4), the Center of foot corresponds to the position of the center of the plantar as described above, and is generally located at 14% of the front end of the entire length of the foot as described above.

In addition, the COP AP position is a position shown as COP' in FIG. 6b. As shown in FIG. 6b, when the subject inclines in the shear direction indicated by the arrow, the distribution of plantar pressure changes as the subject inclines. It means the center of pressure of the plantar pressure changed accordingly.

Furthermore, the COP loadcell position is a position shown as COG' in FIG. 6B. When the subject is inclined in the shear direction indicated by the arrow as shown in FIG. 6B, as the subject is tilted, it is applied to each wire. The pressure distribution by the rods is changed, which means the center of pressure by the changed rods.

As described above, when P derived through Equation (4) is substituted into Equation (2), the tilt angle θ is calculated, and the tilt angle is the maximum under a predetermined balance test condition depending on the condition of the examinee. Values and minimums can be derived.

Thus, through Equation (3), it is possible to finally derive the balance score of the examinee under the conditions of the predetermined balance test.

As described above, based on the calculation result of the equilibrium score in the calculation unit 400, the control determination unit 600 determines whether or not the examinee has a disability, the examinee's current state, and furthermore the balance function of the examinee ( step S60).

7 is an image showing examples of six conditions used in a sensory organization test.

The body posture measuring system and the body posture measuring method using the same in this embodiment can be directly applied to the six conditions of the general balance function or perceptual control test shown in FIG. The state may be finally derived as an equilibrium score through the above-described steps to determine the state of the subject.

According to the embodiments of the present invention, in the case of examining the balance function using only the conventional plantar pressure, the problem of the subject's inability to support the body is solved, and in addition to the subject's plantar pressure, the load generated by holding and supporting the subject is used at the same time to improve the safety of the user during the examination, as well as to improve the accuracy of the examination result and to reduce the examination time.

That is, the balance score is calculated by deriving the inclination angle of the subject's body based on the measurement results for the center of pressure by plantar pressure, the center of pressure by the rod, and the center of the plantar of the subject. can be improved

In particular, the support frame is provided so that the examinee can support himself/herself in an uncomfortable situation, and by using a load that is naturally applied while supporting the body on the support frame for the examination, the accuracy of the examination result for the examinee is further improved.

In this case, the height of the support frame is changed based on the position held by the subject and the position where the subject stands, and after positioning the subject in a more accurate posture and position for the examination, the plantar pressure and the load are measured, Through this, it is possible to perform an optimal test that matches the physical conditions of various subjects.

Measuring the plantar pressure of the examinee in a first pressure measuring unit on the plate portion positioned to stand on the subject;
measuring a load applied from a second pressure measuring unit on a support frame held and supported by the examinee;
calculating a balance score in each posture of the subject based on the measured plantar pressure and load; and
Body posture measurement method comprising the step of determining whether the subject has a disability based on the calculation result of the balance score. The method of claim 8, wherein calculating the equilibrium score comprises:
deriving the subject's inclination angle; and
and calculating a balance score based on the maximum and minimum values of the inclination angle. The method of claim 9, wherein deriving the tilt angle comprises:
calculating a center of pressure by plantar pressure based on the measured plantar pressure;
calculating a center of pressure by the rod based on the measured load; and
and deriving an angle of inclination of the subject's body based on the center of pressure by the plantar pressure, the center of pressure by the rod, and the center of the plantar of the subject. According to claim 8, before measuring the plantar pressure of the subject,
receiving body information of the subject;
measuring a position where the subject stands on the plate unit; and
Body posture measuring method further comprising the step of adjusting the posture of the subject based on the subject's standing position and the position where the subject holds the support frame.
