DETAILED DESCRIPTION OF THE INVENTION

[0019] (Description of the embodiment) An embodiment (example) of the spinal column measuring device according to the present invention will be described below with reference to the drawings.

[0020] It should be noted that the present invention is not limited to the following embodiments. Furthermore, the components in the following embodiments include those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are within the so-called equivalent range. Furthermore, the components disclosed in the following embodiments can be combined as appropriate.

[0021] In addition, since the drawings are schematic diagrams, the main parts are shown and parts other than the main parts are omitted. In addition, the upper side, lower side, left side, and right side in Fig. 2 and the upper side, lower side, front side, and rear side in Fig. 4 indicate the directions of the body of the subject P.

[0022] (Description of the configuration of the embodiment) The configuration of the spine measurement device 1 according to this embodiment will be described below. Hereinafter, the spine measurement device 1 according to this embodiment may be simply referred to as the "spine measurement device 1." Hereinafter, the terms "upper side," "lower side," "left side," "right side," "front side," and "back side" of the spine measurement device 1 correspond to the upper side, lower side, left side, right side, front side, and back side of the subject P when the spine measurement device 1 is measuring the angle of the subject P's spine SV.

[0023] (Explanation of spinal column measurement device 1) 1 to 4, the spine measurement device 1 includes a main body member 2, a roller member 3, an angle sensor 4, a control unit 230, and display units 232, 233L, 233R, and 234. The spine measurement device 1 can screen for scoliosis by measuring the angle of the spine SV of a subject P.

[0024] A normal spine has a straight shape from top to bottom when viewed from the front. However, in the case of scoliosis, the spine is curved to at least one side, either the left or the right, and at the same time, has a twisted shape. Therefore, by measuring the angle of the spine SV of the subject P using the spine measurement device 1, it is possible to screen for scoliosis.

[0025] As shown in Figure 4, the spine SV curves from the buttocks S at the bottom to the neck E at the top, from anterior to posterior and from posterior to posterior. That is, the spine SV forms a concave-convex curve on the anterior or posterior side in the midsagittal plane. The spine measurement device 1 measures the angle of the spine SV while moving from the buttocks S to the neck E along the spine SV, which forms a concave-convex curve on the anterior and posterior sides, as shown by the solid arrow in Figure 4.

[0026] (Explanation of main body member 2) 2 and 4, the main body member 2 moves along the spinal column SV of the subject P from the buttocks S on the lower side to the neck E on the upper side, guided by the roller members 3. As shown in FIGS. 1 to 4, the main body member 2 has a main body section 20, a handle section 21, and electronic device sections 22 and 23.

[0027] The main body 20 has a hollow case structure and is made of a resin material in this example. However, the main body 20 may be made of a material other than a resin material. The upper end of the handle 21 is attached to the center of the lower front edge of the main body 20. The structure and constituent materials of the handle 21 are not particularly limited. Furthermore, the handle 21 may be detachable from the main body 20.

[0028] The electronic device units 22 and 23 are provided in the main body unit 20. The electronic device units 22 and 23 each have a power supply board 22 and a control board 23.

[0029] (Description of power supply board 22) 3, the power supply board 22 has an angle sensor 4, a first movement distance measurement unit 221, a power supply control circuit unit 222, a power supply unit 223, and a USB port 224. The angle sensor 4, the first movement distance measurement unit 221, the power supply control circuit unit 222, the power supply unit 223, and the USB port 224 are housed in the main body unit 20.

[0030] (Explanation of angle sensor 4) 4, the angle sensor 4 is placed at the center of gravity G of the spine measurement device 1 within the main body member 2. The angle sensor 4 detects angle information of the spine SV when the main body member 2, i.e., the spine measurement device 1, moves along the spine SV from the buttocks S of the subject P, which is the measurement start point, to the neck E of the subject P, which is the measurement end point, and outputs this detected angle information to the control unit 230.

[0031] In this example, the angle sensor 4 uses at least one of a gyro sensor, an acceleration sensor, and an angular velocity sensor. Note that the angle sensor 4 may also be a combination of the above-mentioned sensors, such as a MEMS motion sensor and a geomagnetic sensor.

[0032] As shown in Figures 1, 2, and 4, the angle sensor 4 has the origin of its spatial coordinate system at the center of the rotating unit 30 (described later) of the roller member 3, and at the measurement point M. The X-axis of the spatial coordinate system is the rotation axis V of the roller member 3. The Y-axis of the spatial coordinate system is the axis in the direction of the spinal column SV of the subject P, and is the axis in the direction in which the main body member 2 moves along the spinal column SV of the subject P. The Z-axis of the spatial coordinate system is the axis in a direction perpendicular to the spinal column SV of the subject P, and is the axis in a direction perpendicular to the X-axis and Y-axis. The angle sensor 4 and the measurement point M are fixed relative to each other. In this way, the angle sensor 4 detects angle information about the three axes X, Y, and Z at the measurement point M and outputs the information to the control unit 230.

[0033] When the angle sensor 4 detects the rotation or tilt information of the spine SV of the subject P from the buttocks S to the neck E as angle information, it detects angle information such as which position of the spine SV has the greatest rotation or tilt.In order to do this, after measurement begins, the angle sensor 4 integrates the information from the acceleration sensor built into the angle sensor 4 to calculate the distance traveled from the buttocks S and link the position of the spine SV with the rotation or tilt.

[0034] (Explanation of the first movement distance measurement unit 221) The first movement distance measurement unit 221 is disposed in a position closer to the right side of the center of the upper part of the main body 20. An opening 200 is provided in the main body 20 at a position corresponding to the first movement distance measurement unit 221. The first movement distance measurement unit 221 faces the second movement distance measurement unit 33 (described later) via the opening 200 of the main body 20.

[0035] In this example, the first movement distance measurement unit 221 is an optical sensor or a magnetic sensor. The first movement distance measurement unit 221 receives light from multiple reflective surfaces that are the second movement distance measurement unit 33 or magnetism from multiple magnets that are the second movement distance measurement unit 33, and detects the rotation speed of the roller member 3 in a non-contact manner. The control unit 230, which will be described later, then calculates the movement distance from the rotation speed of the roller member 3 detected by the first movement distance measurement unit 221 and the diameter of a rotating unit 30 of the roller member 3, which will be described later, to determine the distance that the main body member 2 moves along the spinal column SV from the buttocks S of the subject P, which is the measurement start point, to the neck E of the subject P, which is the measurement end point.

[0036] (Explanation of power supply control circuit unit 222 and power supply unit 223) The power supply control circuit unit 222 supplies power from a power supply unit 223 to a control unit 230, which will be described later. In this example, the power supply unit 223 is a dry battery. An openable and closable cover 201 for replacing the power supply unit 223, which is a dry battery, is provided on the rear or front side of the main body unit 20. The power supply unit 223 may be a rechargeable battery instead of a dry battery. When the power supply unit 223 is a rechargeable battery, power is supplied from a USB port 224.

[0037] (USB port 224) The USB port 224 is located on the left side of the main body 20. A port opening 202 is provided in a location of the main body 20 corresponding to the USB port 224. The USB port 224 transmits the angle data D acquired and output by the angle sensor 4 to another electronic device, and supplies power to the power supply unit 223 in the case of a rechargeable battery. Note that the USB port 224 may not be provided in some cases.

[0038] (Explanation of control board 23) 3, the control board 23 has a control unit 230, a memory unit 231, display units 232, 233L, 233R, and 234, an audio notification unit 235 as a notification unit, and operation switches 236, 237, and 238. The control unit 230, the memory unit 231, and the audio notification unit 235 are housed in the main body 20. The display units 232, 233L, 233R, and 234 and the operation switches 236, 237, and 238 are provided below the cover 201 on the front side of the main body 20. The display units 232, 233L, 233R, and 234 are provided on the front side of the main body 20 in positions that are easily visible to a measurer, such as a doctor or technician, when the spine measurement device 1 is moving between the buttocks S and the neck E of the subject P while taking measurements.

[0039] (control unit 230) The control unit 230 is composed of other elements including hardware such as a CPU (Central Processing Unit) and a memory portion (e.g., a ROM (Read Only Memory), a RAM (Random Access Memory), a non-volatile memory, etc.). The control unit 230 controls the entire spine measurement device 1 by executing a control application program stored in the memory portion.

[0040] The control unit 230 converts the angle information output from the angle sensor 4 into angle data D by applying a Madwick filter to the angle information.

[0041] (Explanation of storage unit 231) The storage unit 231 has an EEP memory. The storage unit 231 stores, in BUFF, the angle data D output from the control unit 230. The storage unit 231 also stores the angle data D when the angle is corrected to 0.

[0042] (Explanation of auditory notification unit 235) In this example, the auditory alarm unit 235 is a buzzer that emits an electronic sound A. As shown by the electronic sound A in FIG. 6, the auditory alarm unit 235 emits the electronic sound A at approximately 0.5-second intervals after the spine measurement device 1 starts measurement. FIG. 6 is an explanatory diagram of a time chart showing the relative relationship between time T (unit: seconds), the state of the electronic sound A, and the spine SV from the buttocks S to the neck E of the subject P. In FIG. 6, the buttocks S of the spine SV is the measurement start point, and the neck E of the spine SV is the measurement end point. In this way, the auditory alarm unit 235 emits the electronic sound A at approximately 0.5-second intervals while the main body member 2 moves along the spine SV from the buttocks S, which is the measurement start point of the spine SV, to the neck E, which is the measurement end point.

[0043] In the electronic sound A in Figure 6, the thick line indicates the state in which the electronic sound A is sounding, and the thin line indicates the state in which the electronic sound A is stopped. In this example, the time during which the electronic sound A is sounding and the time during which the electronic sound A is stopped are each approximately 0.5 seconds. Therefore, in this example, the time from when the electronic sound A sounds and stops to when the next electronic sound A starts to sound is approximately 1 second.

[0044] In this example, the auditory notification unit 235 emits electronic sound A at 0.5-second intervals 10 times from the start to the end of measurement by the spine measurement device 1. As a result, it takes approximately 10 seconds for the spine measurement device 1 to move from the buttocks S, the measurement start point, to the neck E, the measurement end point. Note that this approximately 10 seconds includes a pause of approximately 0.5 seconds after the electronic sound A stops sounding for the 10th time, as shown in FIG. 6.

[0045] The length of the spine SV of the subject P from the buttocks S to the neck E varies from person to person, but is generally about 400 to 450 mm. Therefore, the measurer, such as a doctor or technician, moves the spine measurement device 1 from the buttocks S to the neck E of the spine SV of the subject P in about 10 seconds. In other words, the measurer moves the spine measurement device 1 a distance of about 40 to 45 mm in about 1 second.

[0046] Auditory notification unit 235 is located on the left side of main body 20. A plurality of small holes 203 are provided in main body 20 at locations corresponding to auditory notification unit 235. Electronic sound A emitted from auditory notification unit 235 is emitted from inside main body 20 through small holes 203 to the outside of main body 20.

[0047] Note that a visual notification unit may be used as the notification unit instead of the auditory notification unit 235. Alternatively, both the auditory notification unit 235 and the visual notification unit may be used. The visual notification unit uses an LED lamp, which issues a notification by turning on and off the LED lamp.

[0048] (Explanation of display units 232, 233L, 233R, 234, operation switches 236, 237, 238) The display units 232, 233L, 233R, and 234 include a first display unit 232, a left-side second display unit 233L, a right-side second display unit 233R, and a differential second display unit 234. The display units 232, 233L, 233R, and 234 are arranged as shown in FIGS. 1 and 2. The arrangement of the display units 232, 233L, 233R, and 234 is not limited to this example. In addition to the display units 232, 233L, 233R, and 234, a display unit that notifies the user that the dry batteries serving as the power supply unit 223 need to be replaced, or a display unit that notifies the user that a rechargeable battery serving as the power supply unit 223 is being supplied with power, may be provided.

[0049] The first display unit 232 displays the angle data D output by the control unit 230 in real time. The first display unit 232 is composed of multiple electronic display units, in this example, 11 LED lamps. The 11 LED lamps are arranged linearly in the left-right direction and in the X-axis direction on the front side surface of the main body 20.

[0050] When the angle data D is approximately 0°, the central LED lamp lights up.

[0051] On the other hand, if angle data D is the maximum angle data and is greater than approximately 0° and less than approximately 2°, the first LED lamp to the left of the central LED lamp will light up. Similarly, if angle data D is the maximum angle data and is greater than approximately 2° and less than approximately 4°, the second LED lamp to the left of the central LED lamp will light up. If angle data D is the maximum angle data and is greater than approximately 4° and less than approximately 6°, the third LED lamp to the left of the central LED lamp will light up. If angle data D is the maximum angle data and is greater than approximately 6° and less than approximately 8°, the fourth LED lamp to the left of the central LED lamp will light up. If angle data D is the maximum angle data and is greater than approximately 8°, the fifth LED lamp to the left of the central LED lamp will light up.

[0052] Furthermore, if angle data D is the minimum angle data and is greater than approximately 0° and less than approximately 2°, the first LED lamp to the right of the central LED lamp will light up. Similarly, if angle data D is the minimum angle data and is greater than approximately 2° and less than approximately 4°, the second LED lamp to the right of the central LED lamp will light up. If angle data D is the minimum angle data and is greater than approximately 4° and less than approximately 6°, the third LED lamp to the right of the central LED lamp will light up. If angle data D is the minimum angle data and is greater than approximately 6° and less than approximately 8°, the fourth LED lamp to the right of the central LED lamp will light up. If angle data D is the minimum angle data and is greater than approximately 8°, the fifth LED lamp to the right of the central LED lamp will light up.

[0053] On the front side of the main body 20, the numbers "10," "8," "6," "4," "2," "0," "2," "4," "6," "8," and "10" are written in order from left to right above the 11 LED lamps of the first display unit 232. These numbers indicate angles, and indicate the angle at which the spine SV at the measurement point M is not rotated or tilted, or the angle at which it is rotated or tilted to the left, or the angle at which it is rotated or tilted to the right.

[0054] The left second display unit 233L displays the MAX angle data as a numerical value. That is, the control unit 230 converts the physical quantity angle, which is the MAX angle data, into a numerical value, and the numerical value is displayed on the left second display unit 233L. In this example, the left second display unit 233L is an LCD, i.e., a liquid crystal display, and is provided on the left side above the first display unit 232 on the front side of the main body 20. That is, the left second display unit 233L is provided in a position corresponding to the left side of the subject P.

[0055] The right-side second display unit 233R displays the min angle data as a numerical value. That is, the control unit 230 converts the min angle data, which is the angle of a physical quantity, into a numerical value, and the numerical value is displayed on the right-side second display unit 233R. In this example, the right-side second display unit 233R is an LCD, i.e., a liquid crystal display, and is provided on the right side above the first display unit 232 on the front side of the main body 20. That is, the right-side second display unit 233R is provided in a position corresponding to the right side of the subject P.

[0056] The difference second display unit 234 displays the difference between the numerical value of the MAX angle data and the numerical value of the MIN angle data. In this example, the difference second display unit 234 is an LCD, i.e., a liquid crystal display, and is provided above the first display unit 232 on the front side surface of the main body 20, between the left second display unit 233L and the right second display unit 233R.

[0057] The numerical values ​​displayed on the left second display unit 233L, the right second display unit 233R and the difference second display unit 234 indicate the angle at which the spine SV at the measurement point M is not rotated or tilted, or the angle at which it is rotated or tilted to the left, or the angle at which it is rotated or tilted to the right.

[0058] (Explanation of operation switches 236, 237, 238) The operation switches 236, 237, and 238 include a first operation switch 236, a second operation switch 237, and a third operation switch 238. The arrangement of the operation switches 236, 237, and 238 is not limited to this example. Furthermore, operation switches other than the operation switches 236, 237, and 238 may be provided as the operation switches.

[0059] The first operation switch 236 is a measurement start / stop switch that starts and stops measurement by the spinal column measurement device 1, and is provided in the center below the first display unit 232 on the front side of the main body 20.

[0060] The second operation switch 237 is a power on / off switch for turning the power of the spinal column measurement device 1 on and off, and is provided on the left side of the first operation switch 236.

[0061] The third operation switch 238 is a calibration switch or a clear switch that performs zero correction of the angle, and is provided to the right of the first operation switch 236.

[0062] (Explanation of roller member 3) 1 to 4, the roller member 3 is attached to the main body member 2 so as to be rotatable about a rotation axis V, and comes into contact with a predetermined part of the subject P directly or via clothing to guide the main body member 2 as it moves along the spinal column SV. The roller member 3 has a rotating part 30, an anti-slip part 31, an attachment part 32, a second movement distance measuring part 33, and a mark 34 as a guideline.

[0063] (Description of the rotating part 30, the non-slip part 31, and the mounting part 32) The rotating unit 30 rotates while in direct contact with a predetermined part of the subject P or through clothing. The rotating unit 30 has a hollow or solid cylindrical shape. The diameter of the central part of the rotating unit 30 in the direction of the rotation axis V is smaller than the diameters of the left and right end parts of the rotating unit 30 in the direction of the rotation axis V. Furthermore, the diameter of the rotating unit 30 gradually changes from both ends to the center, and is smallest at the center. The components of the rotating unit 30 are not particularly limited.

[0064] The anti-slip portions 31 are provided on the circumferential surface of the rotating part 30 that comes into contact with a predetermined part of the subject P, in this example, on the circumferential surface of both the left and right ends. The anti-slip portions 31 may be, for example, a sheet-like material with small irregularities or a sheet-like material with a raised surface, as long as they have an anti-slip effect that prevents the rotating part 30 from slipping and spinning freely when the rotating part 30 rotates while coming into contact with a predetermined part of the subject P. Note that the anti-slip portions 31 do not need to be provided on the entire circumferential surface of the rotating part 30, and it is sufficient that they are provided on an area that has an anti-slip effect.

[0065] The mounting part 32 is made of a rigid round bar member. The left and right end portions of the mounting part 32 are bent in the X-axis direction toward the rotation axis V, and are rotatably attached to the center portions of the left and right end faces of the rotating part 30. The center portion of the mounting part 32 is parallel to the X-axis direction and the rotation axis V direction, penetrates through the upper part of the main body part 20, and is fixed to the main body part 20. As a result, the measurement point M and the angle sensor 4 are fixed relative to each other.

[0066] (Explanation of second movement distance measurement unit 33) The second movement distance measurement unit 33 is provided on the circumferential surface of the rotating unit 30 at a location facing the first movement distance measurement unit 221 through the opening 200 of the main body unit 20. In this example, the second movement distance measurement unit 33 is a plurality of reflective surfaces or a plurality of magnets, which are provided at equal intervals on the circumferential surface of the rotating unit 30. The second movement distance measurement unit 33 intermittently reflects light from the plurality of reflective surfaces or intermittently radiates magnetism from the plurality of magnets. The light intermittently reflected from the plurality of reflective surfaces or the magnetism intermittently radiated from the plurality of magnets passes through the opening 200 of the main body unit 20 and enters the optical sensor or magnetic sensor of the first movement distance measurement unit 221. This allows the rotation speed of the roller member 3 to be detected non-contact, and the control unit 230 calculates the movement distance from the diameter of the rotating part 30 of the roller member 3, thereby determining the distance that the main body member 2 moves along the spinal column SV from the buttocks S of the subject P, which is the starting point of the measurement, to the neck E of the subject P, which is the end point of the measurement.

[0067] (Explanation of Landmark 34) A mark 34 serving as a guideline is attached to the circumferential surface of the rotating unit 30 at the smallest diameter portion in the center of the rotating unit 30. The line direction of this mark 34 coincides with the Y-axis direction. By aligning the line direction of this mark 34 with the spine SV of the subject P, the roller member 3 can be rotated linearly with respect to the spine SV, and the main member 2, i.e., the spine measurement device 1, can be moved linearly from the buttocks S to the neck E of the subject P, supporting the linearity of the angle sensor 4 when acquiring the angle of the spine SV.

[0068] (Handling of spinal column measurement device 1 when measuring the spine) First, we will explain how a measurer, such as a doctor or technician, handles the spinal column measurement device 1 when measuring the spine. The measurer operates the second operation switch 237 to turn on the power of the spinal column measurement device 1. Next, the measurer turns on the third operation switch 238, grasps the handle 21, and places the rotating part 30 of the roller member 3 on the buttocks S, which is the measurement start point of the spine SV of the subject P, and performs angle zero correction. Once preparations are complete, the measurer turns on the first operation switch 236 and moves the main body member 2 in contact with the spine SV to measure the condition of the spine. Specifically, while rotating the rotating part 30 of the roller member 3, the measurer moves the main body member 2 from the buttocks S, which is the measurement start point of the spine SV of the subject P, to the neck E, which is the measurement end point, at a speed of approximately 40 to 45 mm per second. Then, the measurer turns off the first operation switch 236.

[0069] (Explanation of spinal column measurement processing) The spinal column measurement process of the spinal column measurement device 1 will be described with reference to the flowchart of Fig. 5. First, the sampling process shown in A of Fig. 5 will be described.

[0070] When the measurer turns on the first operation switch 236, in step S101, the control unit 230 samples angle information about the three axes X, Y, and Z at the measurement point M detected by the angle sensor 4. Specifically, the control unit 230 acquires angle information about the three axes X, Y, and Z at the measurement point M detected by the angle sensor 4 at predetermined time intervals.

[0071] In step S102, the control unit 230 converts the sampled angle information into angle data D about the Y axis at the measurement point M through high-speed, high-precision processing using a Madgwick filter. Note that the angle data D about the Y axis at the measurement point M will be referred to as Y-axis data YD as appropriate.

[0072] In step S103, the control unit 230 calculates the moving average value of the Y-axis data YD. In this example, the moving average value is calculated for 20 consecutive Y-axis data.

[0073] In step S104, the control unit 230 stores the moving average values ​​of the Y-axis data YD (hereinafter referred to as Y-axis data YDA) in the storage unit 231 in order (stored in BUFF).

[0074] Thereafter, in step S105, the control unit 230 waits for 0.01 seconds, returns to step S101, and repeats the subsequent processes until, for example, the first operation switch 236 is turned off.

[0075] (Explanation of measurement process) The measurement process shown in B of Fig. 5 will be described. When the measurer turns on first operation switch 236, the process starts, and in step S201, control unit 230 acquires one piece of Y-axis data YDA (moving average value of Y-axis data YD) from memory unit 231 in the order stored in memory unit 231 in step S104, and then proceeds to step S202 and step S207, respectively.

[0076] In step S202, control unit 230 determines whether or not Y-axis data YDA acquired in step S201 is larger than maximum Y-axis data YDU stored in a maximum value storage unit (not shown) in storage unit 231. If it is determined in step S202 that Y-axis data YDA is larger than maximum Y-axis data YDU, in step S203 control unit 230 stores Y-axis data YDA in the maximum value storage unit instead of the maximum Y-axis data YDU stored in the maximum value storage unit.

[0077] If it is determined in step S202 that the Y-axis data YDA is not greater than the maximum Y-axis data YDU, or after the processing of step S203, in step S204, control unit 230 determines whether or not the Y-axis data YDA acquired in step S201 is smaller than the minimum Y-axis data YDD stored in a minimum value storage unit (not shown) in storage unit 231. If it is determined in step S204 that the Y-axis data YDA is smaller than the minimum Y-axis data YDD, in step S205, control unit 230 stores the Y-axis data YDA in the minimum value storage unit (not shown) in storage unit 231 instead of the minimum Y-axis data YDD stored in the minimum value storage unit.

[0078] If it is determined in step S204 that the Y-axis data YDA is not smaller than the minimum Y-axis data YDD, or after processing in step S205, in step S206, the control unit 230 converts the maximum Y-axis data YDU stored in the maximum value memory unit and the minimum Y-axis data YDD stored in the minimum value memory unit into integers.

[0079] Steps S201 to S207 will now be described. In step S207, control unit 230 converts the Y-axis data YDA acquired in step S201 into display data for first display unit 232, and the process proceeds to the next step S208.

[0080] In step S208, the control unit 230 turns on or off the 11 LED lamps provided on the back of the numbers "10," "8," "6," "4," "2," "0," "2," "4," "6," "8," and "10" on the first display unit 232 based on the display data.

[0081] After the process of step S206 or step S208 is performed, in step S209, the control unit 230 waits for 0.1 seconds, and then proceeds to the next step S210.

[0082] In step S210, control unit 230 determines whether first operation switch 236 is off. If first operation switch 236 is on, control returns from step S210 to step S201, and if first operation switch 236 is off, control proceeds from step S210 to step S211.

[0083] In step S211, the control unit 230 displays the maximum Y-axis data YDU stored in the maximum value memory unit, the minimum Y-axis data YDD stored in the minimum value memory unit, and the difference between the maximum Y-axis data YDU and the minimum Y-axis data YDD.

[0084] That is, left second display unit 233L displays the numerical value of maximum Y-axis data YDU converted into an integer in step S206 as the angle at which subject P's spine SV has rotated or tilted to the left. Also, right second display unit 233R displays the numerical value of minimum Y-axis data YDD converted into an integer in step S206 as the angle at which subject P's spine SV has rotated or tilted to the right. Furthermore, difference second display unit 234 displays the numerical value of the difference between the numerical value displayed on left second display unit 233L and the numerical value displayed on right second display unit 233R. Then, the measurement process ends.

[0085] Here, when the spine measurement device 1 moves along the spine SV of the subject P from the buttocks S to the neck E to measure the rotation or tilt of the spine SV of the subject P, the first movement distance measurement unit 221 of the main body member 2 and the second movement distance measurement unit 33 of the roller member 3 measure the distance from the buttocks S of the spine measurement device 1. At the same time, the angle sensor built into the angle sensor 4 also measures the distance from the buttocks S of the spine measurement device 1.

[0086] (Explanation of the effect of spinal column measurement device 1) The spinal column measuring device 1 according to this embodiment has the above-mentioned configuration and functions, and the effects thereof will be explained below.

[0087] The spine measurement device 1 according to this embodiment includes a main body member 2, roller members 3, an angle sensor 4, a control unit 230, and display units 232, 233L, 233R, and 234. The angle sensor 4 is located at the center of gravity G of the spine measurement device 1. As a result, the spine measurement device 1 according to this embodiment can suppress errors when the angle sensor 4 detects angle information at the measurement point M, even if the main body member 2 on which the angle sensor 4 is located bends or distorts, or even if the roller members 3 rotatably attached to the main body member 2 bend or distort, or even if the weight balance of the spine measurement device 1 is uneven between the front, back, left, and right. As a result, the spine measurement device 1 according to this embodiment can measure the angle of the spine SV of the subject P with higher accuracy than the spine measurement device of Patent Document 1, in which the three-axis angle sensor of the spatial coordinate collection device is simply provided on the measurement body.

[0088] Moreover, in the spine measurement device 1 according to this embodiment, the angle sensor 4 is located at the center of gravity G of the spine measurement device 1, so it is only necessary to perform zero angle correction before starting measurement. That is, in the spine measurement device 1 according to this embodiment, even if the main body member 2 and the roller members 3 are bent or distorted, the center of gravity G of the spine measurement device 1, where the angle sensor 4 is located, will not bend or distort, so there is no need to perform zero angle correction.

[0089] In the spine measurement device 1 according to this embodiment, the angle sensor 4 has the origin of the spatial coordinate system as measurement point M, and the angle sensor 4 and measurement point M are fixed relative to each other. As a result, the spine measurement device 1 according to this embodiment can maintain a constant relative distance between the angle sensor 4 and measurement point M, allowing the angle sensor 4 to detect angle information at measurement point M with high accuracy, and thereby measuring the angle of the spine SV of the subject P with high accuracy.

[0090] The spine measurement device 1 according to this embodiment is provided with an audio alarm 235 that provides an alarm at predetermined intervals—in this example, every 0.5 seconds—as the main body member 2, i.e., the spine measurement device 1, moves along the spine SV from the measurement start point to the measurement end point. As a result, the spine measurement device 1 according to this embodiment allows the measurer to move the main body member 2, i.e., the spine measurement device 1, at a constant speed from the measurement start point to the measurement end point of the spine SV in time with the sound output from the audio alarm 235. This allows the spine measurement device 1 according to this embodiment to measure the spine SV evenly from the measurement start point to the measurement end point. Furthermore, by moving the main body member 2, i.e., the spine measurement device 1, quickly, the roller members 3 can be prevented from moving away from the spine SV of the subject P, thereby enabling the angle of the spine SV of the subject P to be measured with high accuracy and without measurement errors.

[0091] In the spine measurement device 1 according to this embodiment, the main body member 2 and the roller members 3 are provided with movement distance measuring devices 221 and 33 that measure the movement distance of the main body member 2. As a result, the spine measurement device 1 according to this embodiment can measure the movement distance of the main body member 2 using the movement distance measuring devices 221 and 33, and can calculate the average of the movement distance of the main body member 2 obtained from the acceleration sensor built into the angle sensor 4. This allows the spine measurement device 1 according to this embodiment to reduce errors in the movement distance of the main body member 2, and therefore can measure the angle of the spine SV of the subject P with high accuracy.

[0092] In the spine measurement device 1 according to this embodiment, a rotating unit 30 is provided on the roller member 3, and this rotating unit 30 rotates while in contact with the subject P directly or through their clothing, so that it can reliably detect unevenness, i.e., protrusions and depressions, in the spine SV of the subject P, and therefore can measure the angle of the spine SV of the subject P with high precision without measurement errors. Furthermore, thanks to the rotating unit 30 of the roller member 3, the spine measurement device 1 according to this embodiment does not require the subject P to be naked from the waist up, and can perform measurements even over clothing such as a thin T-shirt.

[0093] In the spine measurement device 1 according to this embodiment, an anti-slip portion 31 is provided on at least a portion of the circumferential surface of the rotating part 30 of the roller member 3 that comes into contact with the subject P, so that the anti-slip portion 31 can come into contact with the subject P directly or through clothing. As a result, the spine measurement device 1 according to this embodiment can reliably rotate while the rotating part 30 of the roller member 3 comes into contact with the spine SV of the subject P, thereby enabling the angle of the spine SV of the subject P to be measured with high accuracy without measurement errors. Moreover, in the spine measurement device 1 according to this embodiment, because the rotating part 30 of the roller member 3 rotates reliably, clothing does not get caught in the rotating part 30.

[0094] In the spine measurement device 1 according to this embodiment, a guideline mark 34 is provided on a circle centered on the rotation axis V at the center of the circumferential surface of the rotating unit 30 in the direction of the rotation axis V, so that the line direction of the mark 34 coincides with the Y-axis direction. As a result, in the spine measurement device 1 according to this embodiment, by aligning the line direction of the mark 34 with the spine SV of the subject P, the roller member 3 can be rotated linearly relative to the spine SV, and the main member 2, i.e., the spine measurement device 1, can be moved linearly from the buttocks S to the neck E of the subject P. This supports the linearity when the angle sensor 4 acquires the angle of the spine SV, preventing measurement errors.

[0095] The spine measurement device 1 according to this embodiment has a control unit 230, which outputs angle information output from the angle sensor 4 as angle data D. The angle data D includes angle data D of 0° when the spine SV is not rotated or tilted, positive angle data D when the spine SV is rotated or tilted to the left of the subject P, and negative angle data D when the spine SV is rotated or tilted to the right of the subject P. As a result, the spine measurement device 1 according to this embodiment can measure the angle of the spine SV of the subject P with high accuracy using the angle data D output by the control unit 230.

[0096] The spine measurement device 1 according to this embodiment has, as display units, a first display unit 232 that displays angle data D in real time, a left-side second display unit 233L that displays positive angle data D as a numerical value, a right-side second display unit 233R that displays negative angle data D as a numerical value, and a differential second display unit 234 that displays the numerical difference between the numerical value of the positive angle data D and the numerical value of the negative angle data D. As a result, the spine measurement device 1 according to this embodiment allows the measurer to perform measurements while looking at the displays 232, 233L, 233R, and 234 using the first display unit 232, the left-side second display unit 233L, the right-side second display unit 233R, and the differential second display unit 234, and therefore can measure the angle of the spine SV of the subject P with high accuracy.

[0097] In the spinal column measurement device 1 of this embodiment, the first display unit 232 is composed of a plurality of electronic display units arranged side by side on the left and right of the subject P in the direction of movement of the main body member 2, the left second display unit 233L is arranged at a position on the main body member 2 corresponding to the left side of the subject P in the direction of movement, the right second display unit 233R is arranged at a position on the main body member 2 corresponding to the right side of the subject P in the direction of movement, and the differential second display unit 234 is arranged between the left second display unit 233L and the right second display unit 233R. As a result, when the spinal column measurement device 1 of this embodiment moves the main body member 2 from the buttocks S to the neck E of the spinal column SV of the subject P to measure, the arrangement of the display units 232, 233L, 233R, 234 provided on the main body member 2 matches the left and right sides of the subject P, so the measurer can accurately grasp the angle data D displayed on the display units 232, 233L, 233R, 234 and the left and right sides of the subject P, and can measure the angle of the spinal column SV of the subject P with high accuracy.
