Description

The present invention is a posture analysis method used for confirming the posture of a person receiving a treatment or training at the site of manual therapy such as chiropractic, manipulative treatment or massage, or training or lesson such as physical training or yoga. It is related to the posture analyzer.

Traditionally, in chiropractic treatment sites, the posture of the person receiving the treatment has been analyzed and used as an index for improving problems. For such posture analysis, the subject is placed backwards on the opposite side of the vertical line hanging from the ceiling side, and the point where the vertical line intersects the floor is positioned at the center of both feet with respect to the vertical line. I was checking what my posture was like. With this method, it was not possible to grasp the posture distortion accurately and in detail, and it was not possible for the subject to confirm what his / her posture was.

Therefore, a method was devised in which the subject was photographed with a camera, captured in a personal computer, and the state was shown to the subject. However, here, a method has been adopted in which markers for measuring distortion are attached to each part of the body, images are taken with a digital camera, data is taken into a personal computer, and analysis is performed using the photographed markers as a reference. However, in such a posture analysis method using a personal computer and a digital camera, it takes time and effort for the practitioner to attach a marker to the subject and transfer the data taken by the camera to the personal computer, and the posture analysis work can be performed quickly.

The posture analyzer of the present invention is composed of a tablet computer 1 having a camera function, and specifically uses iPad (a trademark of Apple Inc.). The tablet computer 1 includes a camera 2, a control unit 3, a touch panel display 4, and an acceleration sensor 5. The control unit 3 controls the overall operation of the tablet computer 1, and particularly includes a camera operating unit 6, a verticality display unit 7, an index portion display unit 8, and an inclination angle display unit 9. .. The camera operating unit 6 has a function of displaying the subject on the touch panel display 4 and taking a picture, and the verticality display unit 7 is the camera 2 measured by the acceleration sensor 5, the touch panel display 4, or the tablet computer. The touch panel display 4 has a function of displaying the verticality of the front-back direction and the left-right direction of 1, and the index portion display unit 8 has a function of setting and displaying the touch position on the touch panel display 4 as an index portion, and tilts. The angle display unit 9 has a function of displaying the degree of distortion of the set index portion on the touch panel display 4.

The procedure for analyzing the posture of the side surface of the subject with this posture analyzer 1 will be described. First, the camera operating unit 6 is activated and the side mode is selected. Then, the camera 2 is directed toward the subject, and the side surface of the subject is displayed on the touch panel display 4 as shown in FIG. At this time, since the touch panel display 4 displays the long vertical guideline 10 and the short horizontal guideline 11 vertically intersecting the upper and lower parts thereof, the side surface of the subject is displayed on the vertical guideline 10. Adjust so that the image of the subject fits within the short guideline 11 above and below. At the same time, the inclination of the left, right, front and back is adjusted so that the vertical detection marker 12 displayed at the lower left indicates vertical. The vertical detection marker 12 displays the detection result of the acceleration sensor 5 in real time. As shown in the drawing of FIG. 2, for example, when the upper part of the device is tilted in front of the point and to the left, the center circle (black circle) of the vertical detection marker 12 is displayed so as to lean toward the front and to the left. , Adjust the angle (vertical degree) of the tablet computer 1 so that the central circle is located at the center. When the vertical detection marker 12 displays vertical as shown on the right side of the drawer diagram, the color of the shutter button 19 displayed on the lower right side is displayed darkly as shown in the drawer diagram and can be touched. Therefore, the shutter button 19 can be touched. Tap to shoot. Then, as shown in FIG. 3, the side shot image of the subject according to the guideline 10 and the guideline 11 is displayed on the touch panel display 4.

On the touch panel display 4, the captured image can be pinched out, enlarged / reduced by pinch-in, and moved up / down / left / right by swiping, so that a slight deviation from the guidelines 10 and 11 can be corrected. Next, tap "Save and analyze" to activate the index part display unit and proceed to the analysis screen shown in FIG. On the analysis screen, the characters "top of head", "ears", "shoulders", "waist", "knees", and "ankle" are displayed as indicators. The "ear" specifically indicates the "ear hole", the "shoulder" indicates the "deltoid muscle", and the "lumbar" indicates the "third lumbar vertebral body". When one of them is selected and tapped, the index site detection marker 13 appears. As shown in FIG. 5, when the index site detection marker 13 is swiped to move and released, the marker 13 disappears, a point is replaced at the tip position of the marker 13, and the image corresponding to the selected index site on the image is displayed. The above measurement point is set. As shown in FIG. 6, when all the index parts are set, the inclination angle with respect to the vertical 26 between the respective index parts (20, 21, 22, 23, 24, 25) is automatically measured and displayed. In FIG. 6, the vertical line 26 is displayed at the guideline 10 position.

For example, in order to set the ear canal accurately, it is preferable to enlarge the image at the time of designation with the index site detection marker 13, but for enlargement, as shown in FIG. 7, the index site detection marker 13 is touched. During that time, only the periphery of the index site detection marker 13 is enlarged. For example, as shown in FIG. 8, the inclination angle between the index parts is measured when the straight line 27 passing through the deltoid muscle 22 and the ear canal 21 is in the clockwise (CW) direction with respect to the vertical line passing through the deltoid muscle 22. If it is negative or counterclockwise (CCW), it will be displayed as positive.

Next, a procedure for analyzing the posture of the back surface of the subject with the posture analyzer 1 will be described. Select the back mode when analyzing the standing back of the subject. Then, as in the case of the side mode, the touch panel display 4 may display a long guideline 10 in the vertical direction and a short guideline 11 in the horizontal direction vertically intersecting the upper part and the lower part thereof. Adjust the position of the camera 2 so that the back of the examiner is along and the image of the examinee fits within the guideline 11. Further, as in the side mode, the vertical detection marker 12 is used to check the verticality of the camera 2, the touch panel display 4, or the tablet computer 1. Then, the camera 2 is held vertically and the shutter button 19 is tapped to take a picture. Here, as in the side mode, the captured image can be enlarged / reduced by pinch-out / pinch-in and moved up / down / left / right by swiping. Then, when the index part display unit 8 is started and "Save and analyze" is tapped, the analysis screen is displayed, and the index parts are "top of head", "ears", "shoulders", "waist", "elbows", "wrist", "knees", and "knees". The word "heel" is displayed. "Ear" specifically indicates "earlobe", "shoulder" specifically indicates "acromion", and "waist" specifically indicates "iliac crest". Then, when one of the eight index sites is selected and tapped, the index site detection marker 13 appears. Swipe the index site detection marker 13 to move, and when the hand is released, the index site detection marker 13 disappears. The point indicating the index site is replaced with the tip position of the marker, and the measurement point on the image is set. A pair of left and right measurement points are set at each index site position except for the crown. When the index parts (28, 29, 30, 31, 32, 33, 34, 35) are set, the inclination angle with respect to the horizontal between the index parts is automatically measured and displayed. Here as well, as in the side mode, while the index portion setting marker 13 is touched, only the periphery of the marker 13 is enlarged.

The measurement of the inclination angle between the index portions is performed by drawing a straight line 36 passing through the left and right acromions 30 and inclining the straight line 36 from the horizontal, for example, as shown in FIG. The tilt angle is negative if the right shoulder is low, and positive if the left shoulder is low.
