Abstract
Description
[Technical field]
[0001] The present invention relates to a postural balance measurement system for measuring the postural balance of a subject, and a postural balance measurement method using the same. More particularly, the present invention relates to a postural balance measurement system using a subject safety device, which measures the subject's balance function by using a harness fixed to the subject for the subject's safety and a scaffold plate on which the subject stands in order to test the subject's balance function such as dizziness, and a postural balance measurement method using the same. [Background technology]
[0002] Generally, the Sensory Organization Test involves selectively applying stimuli to the visual sense, somatosensory sense, etc. under six different conditions using the center of pressure of the foothold, and judging the results based on the balance score under each condition.
[0003] Such a sensory integration function test is a representative method for testing the subject's balance function, such as dizziness, and in testing such balance function, as in Korean Patent Registration No. 10-0921513, many testing methods are applied that use a plantar pressure measuring device to measure only the plantar pressure.
[0004] However, when testing such balance function using only the plantar pressure of the footrest on which the subject is standing, if the subject is elderly or suffers from severe dizziness or psychological anxiety, they may slip off the footrest during the test or rely on supports such as safety devices or walls located around the testing device. When such a situation occurs, it causes errors in the measured balance score and also leads to problems such as longer test times.
[0005] As a result, simply measuring plantar pressure while the subject is positioned on a platform can result in inaccurate balance function test results, and repeated measurements are necessary, causing inconvenience and inefficiency for both the subject and the examiner.
[0006] Related prior art documents include Korean Patent Registration No. 10-0921513. DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]
[0007] The present invention has been made with this in mind, and an object of the present invention is to provide a posture balance measurement system using a subject safety device that can measure the subject's balance function, such as dizziness, by using a harness that is fixed to the subject for the subject's safety and a scaffold plate on which the subject is positioned, thereby enabling more accurate testing to be performed, and that can simultaneously fix the subject's body and measure it without the need to install a separate measurement module.
[0008] Another object of the present invention is to provide a posture balance measuring method using the posture balance measuring system. [Means for solving the problem]

A subject stands on the plate. The pressure measurement unit is provided on the plate and measures the plantar pressure of the subject. The harness fixes and supports the torso of the subject. The balance measurement unit is provided on the harness and measures balance information of the subject. The control unit controls the pressure measurement unit and the balance measurement unit by performing an examination. The evaluation and diagnosis unit diagnoses the posture balance of the subject based on the pressure information of the subject derived by the pressure measurement unit and the balance information of the subject derived by the balance measurement unit.
[0010] The pressure measurement unit includes a posture adjustment unit that adjusts the posture of the plate to match the posture of the subject when the subject stands on the plate and initializes the pressure measurement unit, a pressure measurement unit that measures the subject's plantar pressure as the test is performed, a pressure change analysis unit that analyzes pressure changes from the measured plantar pressure, and a pressure information recording unit that records the measured pressure and pressure changes.
[0011] The balance measurement unit includes a balance information initialization unit that initializes the balance measurement unit in accordance with the posture of the subject when the subject is fixed to the harness, a balance information measurement unit that measures the balance state of the subject by performing the test, a balance change analysis unit that analyzes balance changes from the measured balance state, and a balance information recording unit that records the measured balance state and balance changes.
[0012] The balance information measurement unit includes at least one of an acceleration sensor, a gyro sensor, and a magnetic sensor that measure the balance state of the subject.
[0013] The balance information measurement unit further includes a first joint sensor provided on the subject's thigh, a second joint sensor provided on the subject's shin, and a third joint sensor provided on the subject's foot.
[0014] The first joint sensor together with the gyro sensor measures the joint angle between the subject's hip and thigh, the first joint sensor together with the second joint sensor measures the joint angle between the subject's thigh and shin, and the second joint sensor together with the third joint sensor measures the joint angle between the subject's shin and foot.
[0015] The harness includes a pair of first and second fixing parts for fixing the upper part of the subject, and a third fixing part connected to the first and second fixing parts for fixing the abdomen of the subject.
[0016] The balance measurement unit is provided on the third fixed portion.
[0017] A posture balance measurement method according to one embodiment for achieving another object of the present invention includes the steps of a subject standing on a plate and the subject's torso being fixed to a harness, adjusting the posture of the plate to match the subject's posture, initializing a pressure measurement unit and a balance measurement unit, measuring the plantar pressure of the subject using the pressure measurement unit, measuring balance information of the subject using the balance measurement unit, and diagnosing the postural balance of the subject based on the pressure information of the subject derived by the pressure measurement unit and the balance information of the subject derived by the balance measurement unit.
[0018] The pressure measuring unit measures the plantar pressure of the subject due to the execution of the test and analyzes the pressure change, and the balance measuring unit measures the balance state of the subject due to the execution of the test and analyzes the balance change. Effect of the Invention
[0019] According to the present invention, the problem of reduced accuracy of the test when testing balance function using only plantar pressure, which is different from the conventional harness that only serves to support the subject and measures plantar pressure using only the lower plate, can be solved.
[0020] In other words, by providing a balance measurement unit on the harness supporting the subject, balance information can be measured in addition to fixing the upper part of the subject, and together with the plantar pressure information, postural balance of the subject can be measured more accurately.

[0026] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
[0027] Fig. 1 is a schematic diagram showing a posture balance measurement system according to an embodiment of the present invention. Fig. 2 is a perspective view showing an example in which the posture balance measurement system in Fig. 1 is realized. Fig. 3 is a schematic diagram showing a state in which a subject is fixed to a harness in Fig. 2, and hardware of a balance information measurement unit.
[0028] First, as shown in Figures 1 and 2, the posture balance measurement system 10 according to this embodiment includes a wire section 20, a frame section 40, a plate 50, a harness 60, an information input section 70, a pressure measurement unit 100, a balance measurement unit 200, a control section 300, and an evaluation diagnosis section 400.
[0029] The frame portion 40 is a structure that forms a space in which the subject 30 is positioned and to which the harness 60, the wire portion 20, etc. are fixed, and as shown in Figure 2, includes a lower frame 41, a side frame 42, and upper frames 43, 44, and 45.
[0030] The lower frame 41 is located on the ground and is a frame that, as a whole, fixes and supports the frame portion 40, and the side frame 42 is a frame that extends upward from the lower frame 41 and forms the side of the frame portion 40.
[0031] The upper frames 43, 44, and 45 are connected to the upper part of the side frame 42 and correspond to frames to which the wire unit 20 is directly fixed.
[0032] The wire portion 20 includes three different wires, namely, first to third wires 21, 22, and 23, and the first to third wires 21, 22, and 23 are fixed to the upper frames 43, 44, and 45, respectively.
[0033] However, the structure of the upper frames 43, 44, 45 and the connection relationship of the wires 21, 22, 23 are merely examples, and the structure and connection state can be changed in various ways.
[0034] Furthermore, the frame portion 40 can be formed into various structures other than the structure shown in FIG. 2, and the structure is not limited thereto.
[0035] The plate 50 is positioned at the center of the lower frame 41, and the subject 30 stands with both feet placed on the plate 50 to have his / her balance function tested.
[0036] In this case, the pressure measuring unit 100 is provided in the center of the plate 50 at the location where both feet of the subject are positioned.
[0037] The pressure measurement unit 100 measures and analyzes the plantar pressure of the subject, in which case the information measured from the plantar pressure of the subject includes the overall plantar pressure distribution, the magnitude of plantar pressure, the average plantar pressure, changes in plantar pressure, etc.
[0038] More specifically, the pressure measurement unit 100 includes a posture adjustment unit 110, a pressure measurement unit 120, a pressure change analysis unit 130, and a pressure information recording unit 140, as shown in FIG.
[0039] When a subject stands on the plate 50 , the posture adjustment section 110 adjusts the posture of the plate 50 in accordance with the posture of the subject, and further initializes the pressure measurement unit 100 .
[0040] That is, the posture of the plate 50 adjusted to match the posture of the subject is set as an initial posture, and the pressure measuring unit 100 is initialized based on this initial set posture.
[0041] Each subject has a different standing posture due to various factors such as body shape and posture, and therefore the posture of the subject in a normal equilibrium state differs from subject to subject. Therefore, in this embodiment, the posture of the plate 50 is adjusted taking into consideration such postures of the subjects in a normal equilibrium state, and the information of the pressure measurement unit 100 is initialized based on the posture of the plate 50 thus adjusted. Thus, it is possible to derive more accurate pressure information for each subject.
[0042] When the test is performed while the subject is standing on the plate 50, the test causes the subject's standing posture to change, and the pressure measuring unit 120 measures the pressure due to the plantar pressure of the subject caused by such a change in the subject's standing posture.
[0043] That is, the subject stands on the plate 50 and undergoes a balance test for six conditions for determining dizziness as shown in FIG. 7. For each test, the subject changes his / her standing posture, and the pressure measuring unit 120 measures the pressure due to the plantar pressure caused by such changes in the subject's standing posture.
[0044] In order to measure such pressure due to plantar pressure, the pressure measuring unit 120 is, for example, a pressure sensor, and in order to measure the distribution of plantar pressure, a plurality of pressure sensors are distributed at predetermined intervals and in a predetermined arrangement in the area where both feet are located.
[0045] The pressure change analysis unit 130 analyzes the pressure change or pressure distribution change when a balance test is performed to determine dizziness, based on the pressure due to the plantar pressure measured by the pressure measurement unit 120, or the pressure distribution, which is the distribution of plantar pressure, by comparing it with the subject's initial standing posture.
[0046] Furthermore, the pressure or pressure distribution information measured by the pressure measurement unit 120 and the pressure change or pressure distribution change information analyzed by the pressure change analysis unit 130 are recorded in the pressure information recording unit 140.
[0047] Meanwhile, the harness 60 is a structure that is located in a predetermined space formed by the frame portion 40 and supports the torso of the subject. The harness 60 is also located above the plate 50.
[0048] Thus, the subject's balance test is performed with the subject's torso, i.e., the upper part of the subject, secured by the harness 60, and for this reason, the harness 60 is formed in a shape similar to that of a chair that can secure and support the subject's waist, upper torso, etc.
[0049] In this case, the harness 60 can be formed in various shapes.
[0050] In this embodiment, the balance measuring unit 200 is fixed onto the harness 60, and the balance measuring unit 200 will be described with reference to FIG.
[0051] That is, referring to Figures 1 and 3, the harness 60 includes a pair of first and second fixing parts 61, 62 that fix the upper part of the subject, i.e., a pair of shoulders, and a third fixing part 63 that fixes the abdomen of the subject and is connected to the first and second fixing parts 61, 62.
[0052] In this case, the balance measurement unit 200 is fixed on the third fixing portion 63 .
[0053] Of course, the harness 60 is in a form that fixes the upper part of the subject, and when the balance measuring unit 200 is provided on the harness 60, it can be designed into various structures other than the structure shown in FIG.
[0054] Thus, in this embodiment, the harness 60 secures the upper part of the subject, and when the subject is secured by the harness 60 and the posture changes due to a balance test, such posture change, i.e., the balance state, can be measured simultaneously by the balance measurement unit 200.
[0055] Furthermore, the information on the balance state measured by the balance measurement unit 200, together with the information on the pressure measured by the pressure measurement unit 100, is used as information for evaluating or diagnosing the subject's postural balance, thereby improving the accuracy of the evaluation or diagnosis of the subject's postural balance.
[0056] More specifically, the balance measurement unit 200 includes a balance information initialization unit 210 , a balance information measurement unit 220 , a balance change analysis unit 230 , and a balance information recording unit 240 .
[0057] When the subject stands on the plate 50 and the upper torso is fixed to the harness 60, the balance information initialization unit 210 initializes the balance measurement unit 200 according to the subject's posture.
[0058] In other words, the harness 60 is fixed to the subject and its position and posture are set to match the posture of the subject, and therefore the balance measurement unit 200 fixed on the harness 60 also needs to be initialized based on such initial posture of the subject.
[0059] As described above, each subject has various standing postures depending on various factors such as body shape and posture, and therefore the posture of the subject in a normal balanced state differs from subject to subject. Therefore, in this embodiment, when the harness 60 is fixed to the subject, taking into consideration such postures of the subjects in a normal balanced state, the information of the balance measurement unit 200 is initialized based on the balance state of the harness 60 thus fixed and the balance measurement unit 200 provided thereon. Thus, it is possible to derive more accurate balance state information for the subject.
[0060] When an examination is performed with the subject fixed on the harness 60, the test causes a change in the subject's standing posture or balance posture, and the balance information measurement unit 220 measures the subject's balance state due to such change in the subject's standing posture or balance posture.
[0061] In this case, the balance information measuring unit 220 includes at least one of an acceleration sensor 201, a gyroscope 202, and a magnetometer 203, as shown in FIG.
[0062] Moreover, the balance information measurement unit 220 further includes a sensor control unit 204 that controls these sensors, and a wireless communication module 205 that provides measurement information to the balance change analysis unit 230 and the control unit 300 by wireless communication.
[0063] Thus, when the subject's standing posture or balance posture changes as a result of the test, the balance information measurement unit 220 can effectively measure the balance state of the subject using the sensors 201, 202, and 203.
[0064] That is, as described above, the subject is fixed to the harness 60 and undergoes a balance test for six conditions for determining dizziness as shown in FIG. 7. For each test, the subject's standing posture or balance state changes, and the balance information measurement unit 220 measures the balance state due to such changes in the subject's standing posture or balance state.
[0065] The balance change analysis unit 230 analyzes the change in balance state, i.e., the balance change, when a balance test for each dizziness judgment is performed based on the balance state information measured by the balance information measurement unit 220 and comparing it with the subject's initial standing posture.
[0066] Further, the balance state information measured by the balance information measuring unit 220 and the balance change information analyzed by the balance change analyzing unit 230 are recorded in the balance information recording unit 240 .
[0067] Meanwhile, the information input unit 70 receives various information about the subject, for example, identifies the subject using an identification means (not shown) for identifying the subject, and retrieves recorded information about the subject to input the relevant information, or information about height, weight, muscle mass, skeletal structure, etc. can be directly input through the subject or an operator.
[0068] In addition, the subject information input in this manner is used by the pressure measurement unit 100 and the balance measurement unit 200 to initialize information such as the subject's posture, or is used as a reference when measuring pressure or balance state relative to posture or balance state.
[0069] Meanwhile, the control unit 300 generally controls the pressure measurement or balance state measurement in the pressure measurement unit 100 and the balance measurement unit 200, and more specifically, controls the operation of the posture adjustment unit 110, the pressure measurement unit 120, the pressure change analysis unit 130, and the pressure information recording unit 140, or controls the operation of the balance information initialization unit 210, the balance information measurement unit 220, the balance change analysis unit 230, and the balance information recording unit 240.
[0070] Further, the overall operation of the posture balance measurement system 10 is controlled by the control unit 300 .
[0071] The evaluation and diagnosis section 400 evaluates and diagnoses the postural balance state of the subject based on the analysis results of the pressure change or pressure distribution change of the subject derived by the pressure measurement unit 100 and the analysis results of the balance state change of the subject derived by the balance measurement unit 200.
[0072] That is, for six conditions used in a sensory integration function test as shown in FIG. 7 described later, the subject's posture balance state or the presence or absence of dizziness is evaluated based on the pressure change or pressure distribution change derived by the pressure measurement unit 100 and the balance state change derived by the balance measurement unit 200, and a final diagnosis is made.
[0073] Furthermore, although not shown, the judgment results of the evaluation and diagnosis unit 400 as to whether the subject has a disability, the subject's current condition, and the subject's balance function, as well as the final judgment results and related information, are displayed externally by a display unit (not shown).
[0074] Fig. 4 is a schematic diagram showing a state in which a subject is fixed to the harness in Fig. 2, and another example of hardware of the balance information measurement unit. Figs. 5a to 5c are graphs showing examples of posture balance measurement results measured by the balance information measurement unit in Fig. 4.
[0075] As shown in FIG. 4, the balance information measurement unit 220 includes at least one of the acceleration sensor 201, the gyro sensor 202, and the magnetic sensor 203 as in FIG. 3, and further includes first to third joint sensors 206, 207, and 208.
[0076] In this case, the first joint sensors 206 are provided in a pair on the thighs of the subject 30 (i.e., the left thigh and the right thigh), the second joint sensors 207 are provided in a pair on the shank of the subject 30, and the third joint sensors 208 are provided in a pair on the foot.
[0077] Each of the first to third joint sensors 206, 207, and 208 is an inertial measurement unit.
[0078] Thus, the first to third joint sensors 206, 207, 208 sense the joint angle between the ankle joints of the subject 30. In this case, the gyro sensor 202 located at the waist of the subject 30 can simultaneously sense such a joint angle together with the first joint sensor 206.
[0079] That is, when the subject's standing posture or balance posture changes as a result of the test, the balance information measurement unit 220 measures the balance state of the subject 30 using the acceleration sensor 201, gyro sensor 202, and magnetic sensor 203, and also measures the balance state by measuring the joint angles between the subject's segments using the first to third joint sensors 206, 207, and 208.
[0080] Thus, the balance change analysis unit 230 measures the balance state change of the subject based on the balance state information measured by the balance information measurement unit 220 as described above, and in measuring such balance state change, analyzes the balance state change or posture change by simultaneously or separately considering information on the inter-segment joint angles of the subject.
[0081] Thus, examples of changes in balance state or posture analyzed in the balance change analysis unit 230 based on information on the inter-segment joint angles of the subject are shown in FIG. 5a to FIG. 5c.
[0082] That is, as shown in Figures 5a to 5c, the first joint sensor 206, together with the gyro sensor 202, can measure the joint angle between the subject's lumbar and thigh (Figure 5a), the first joint sensor 206, together with the second joint sensor 207, can measure the joint angle between the subject's thigh and shank (Figure 5b), and the second joint sensor 207, together with the third joint sensor 208, can measure the joint angle between the subject's shank and foot (Figure 5c).
[0083] Furthermore, such joint angles can be measured for each of the subject's two feet.
[0084] Fig. 6 is a flowchart showing a posture balance measurement method using the posture balance measurement system of Fig. 1. Fig. 7 is an image showing examples of six conditions used in the sensory integration function test.
[0085] As shown in FIG. 5, in the posture balance measuring method using the posture balance measuring system 10 of FIG. 1, first, various information of the subject 30 is input by the information input unit 70 (step S10).
[0086] In this case, the information to be input includes various physical information such as the subject's height, weight, muscle mass, and skeletal structure.
[0087] Thereafter, the subject 30 stands on the plate 50, and the subject's torso is fixed to the harness 60 (step S20).
[0088] Thereafter, the posture adjustment unit 110 adjusts the posture of the plate 50 to match the posture of the subject 30 (step S30), and based on the standing posture and balance state of the subject 30, the posture adjustment unit 110 initializes the pressure measurement unit 100, and the balance information initialization unit 210 initializes the balance measurement unit 200 (step S40).
[0089] After this, a measurement step (step S50) is performed, that is, the pressure measurement unit 120 measures the plantar pressure or plantar pressure distribution of the subject by conducting an examination on the subject (step S51), and the balance information measurement unit 220 measures the balance information of the subject by conducting an examination on the subject (step S52).
[0090] In this case, in the measurement step, a test is performed on the subject under six conditions used in a sensory integration function test, as shown in FIG.
[0091] Thereafter, the pressure change analysis unit 130 analyzes pressure change or pressure distribution change information based on the measured pressure information or pressure distribution information (step S60), and the balance information analysis unit 230 analyzes balance change information based on the measured balance information (step S60).
[0092] Thereafter, the evaluation and diagnosis unit 400 performs a final evaluation and diagnosis of the posture balance of the subject based on the results of the analyses performed by the pressure change analysis unit 130 and the balance information analysis unit 230 (step S70).
[0093] According to the present invention, the problem of reduced accuracy of the test when testing balance function using only plantar pressure, which is different from the conventional harness that simply serves to support the subject and measures plantar pressure using only the lower plate, can be solved.
[0094] In other words, a balance measurement unit is provided on the harness supporting the subject, and balance information can be measured in addition to fixing the upper part of the subject, so that the postural balance of the subject can be measured more accurately along with the plantar pressure information.
[0095] While the present invention has been described above with reference to preferred embodiments, those skilled in the art will appreciate that various modifications and variations of the present invention may be made without departing from the spirit and scope of the present invention as set forth in the following claims.
