Description

TECHNICAL FIELD The present invention relates to a body range of motion angle measuring device and a measuring method, and more particularly to a body range of motion angle measuring device and a measuring method for measuring a motion angle of a joint range of motion.

In humans, which are vertebrates, joints are joints that connect bones in the endoskeleton, and have the function of freely moving the body and the function of supporting the body. The joint range of motion indicates how much the joint can move. The amount of joint range of motion is determined by how tightly the ligaments, tendons, muscles and joint capsule surround the joint.

By the way, applicants have proposed a method of using a stretching machine as a method of increasing joint range of motion and flexibility.

Specifically, the applicant has developed a dynamic stretching machine, Reflexible, which uses a low-load plate (or a means for generating tensile force) to perform repetitive motions while relaxing, thereby improving flexibility and improving joint flexibility. We are proposing a device that has effects such as increasing the range of motion, promoting blood circulation, nerve transmission, improving function, improving movement, rehabilitation, and recovering from fatigue.

Conventional strength training machines aim to improve muscle strength and muscle hypertrophy by exerting force against the load (or tensile force generating means) of a plate that has a certain amount of weight. is characterized in that it moves while weakening without resisting a low-load plate (or tensile force generating means).

It has not been proposed to specifically measure this joint range of motion as an objective numerical value. Conventional strength training machines have only been proposed to measure the number of weights and their movement distance.

For example, Patent Literature 1 proposes a muscle strength measuring device and a muscle strength measuring method.

Japanese Patent No. 6258609

In the muscle strength measurement in Patent Document 1, it was intended to measure what kind of weight weight was moved by what distance and how many times, but it was not intended to measure the angle of the range of motion of the joint.

In other words, until now, both conventional muscle training machines that apply loads to strengthen muscles and conventional stretching machines that stretch muscles and joints have been shown to increase joint range of motion as a result of training. Although machine users have felt it, no method has been proposed for objectively measuring joint range of motion angles.

For this reason, it has not been possible to objectively compare one's past joint range-of-motion angle and one's current joint range-of-motion angle. Furthermore, they were not able to compare their current joint range of motion angles with the joint range of motion angles of third parties. In addition, as long as there is no objective numerical value, there is naturally no reference value for the joint range of motion angle, and for this reason, a method for objectively evaluating the joint range of motion angle has not been established.

On the other hand, in the process of developing conventional muscle training machines or stretching machines, the inventors discovered that it was possible to numerically display the range of motion of the joints in terms of angles while operating these machines. I figured it out.

Until now, it has been physically possible to measure the angle of a joint by directly applying a protractor to the joint during training, but this is not easy because the fulcrum is not fixed. It was necessary to temporarily stop the opening of the opening, and a third party was required to measure the angle, so it was not easy to adopt as a practical method.

An object of the present invention is to provide a range-of-motion angle measuring device for measuring joint range-of-motion angles and a measuring method thereof.

Child device 90, display unit 98, IC tag antenna 91, parent device 108, router 106, and cloud 109 are activated. It is assumed that the Internet 112 is always running. On the other hand, the transmitter/receiver 60 initially does not emit light or receive light to prevent malfunction.

Next, the IC tag antenna 91 enters a standby state and stays in the A4 step in standby until the IC tag is touched. If the IC tag is touched, proceed to the next step (A4).

When the IC tag is touched, the IC tag antenna 91 reads the band ID of the IC tag and sends it to the slave device 90 , and the slave device 90 reads the band ID touched by the master device 108 via the wireless interface 96 and the antenna 121 and the slave device 90 .

Following step A12, as shown in FIGS. 7, 8 and 10B, the CPU 93 of the handset 90 further causes the display unit interface 100 to display the band ID and model (A14). At this point, the initial displacement maximum is 0 if the user has not activated the device. The number of moves is 0 at the beginning as well.

Here, the child device 90 detects whether or not the IC tag is touched via the IC tag antenna 91 (A16).

If the IC tag is not touched, the process proceeds to the maximum movement determination step (A18).

If the IC tag is touched, the process proceeds to the data storage step (A20).

In the step of determining the maximum movement (A18), first, when the operation of the light transmitting/receiving unit 60 is started, the reflective marker 66 provided on the weight extending portion 67 bent vertically so as to be parallel to the short side of the weight 46 is Detect the position of The 0-degree reference point of the reflective marker 66 pushes the arm 18 down the most, and conversely, the position of the reflective marker 66, which is positioned when the weight 46 is raised to the highest position, is parallel to the uppermost part of the facing light transmitting/receiving element 68. position of the weight 46. In one motion, the arm 18 is raised from the 0 degree reference point and the U-handle connected to the arm 18 is also raised to bend the elbow of the user's arm and raise the arm and shoulder. Since the position of the weight 46 is lowered accordingly, the transmitter/receiver 60 measures the displacement (n) from the 0-degree reference point (FIG. 12). This displacement value is compared with the maximum displacement value measured so far today to determine whether the measured displacement value is larger.

When the measured displacement value is larger, the process proceeds to the conversion step (A22), and when the measured displacement value is smaller, the increment step (A24) is performed.

In the conversion step (A22), the CPU 93 of the handset 90 proportionally calculates the angle corresponding to the displacement using the model-specific maximum movement distance and model-specific maximum angle unique to the XBee-ID (proportional division calculation method).

Here, the maximum movement distance for each model is the distance that the reflective marker 66 can move from the 0 degree reference point, which is the maximum distance that it can move due to its structure, and is the distance determined for each model. It is a distance beyond which it cannot move. In this embodiment, the distance is determined by structural restrictions, such as the arm 18 coming into contact with the arm support frame 8 so that the rotary shaft 16 cannot rotate any further.

The model-specific maximum angle is an angle corresponding to the model-specific maximum movement distance, and is an angle at which no further movement is allowed.

That is, the proportional division calculation method is a calculation method for calculating the angle from the product of the model-specific maximum angle proportionally divided by the model-specific maximum movement distance and the displacement.

Further, the CPU 93 updates the angle calculated in A22 as the maximum angle, causes the display unit interface 100 to display the maximum angle, the band ID, the number of times of movement, and the movement distance, and proceeds to step A24 (A26 ).

In the increment step (A24), the weight 46 has been moved once by the above operation, so one is added to the number of times of movement. Proceed to the IC tag confirmation step (A16) again.

Here, the case of proceeding to step A20 when an IC tag exists in the IC tag confirmation step (A16) will be described. Since the maximum distance, maximum angle, and number of times data at this point become the user's maximum distance, maximum angle, and number of times data for the day at this point, including the band ID and XBee-ID, It is stored in exercise data 122 via child device 90, parent device 108, router 106, web server 118, and DB server 116 (A20).

The child device 90 transmits the maximum distance value, the maximum angle value, and the number of times data to the master device 108, and stops the sensor operation by turning off the power of the light transmitting/receiving unit 60 without turning off the power of the child device 90 (A28 ). This stops the operation (A30).

Here, in the terminal 110, the motion range angle creation program pre-installed in the terminal 110 used by the user who is the customer is activated, and the IC tag antenna 110A connected to the terminal 110 is activated. When the user who uses the present invention completes all the measurements for the day with this system and touches his/her band ID to the IC tag antenna 110A connected to the terminal 110, the range of motion angle creation program is sent from the terminal 110 to the router 106 , the Internet 112 , and the web server 118 to request exercise data from the DB server 116 .

From the exercise data 122, the DB server 116 searches angle data for multiple days, actually 24 days, for each XBee-ID, stored in association with the band ID, by generating an SQL statement, and retrieves them. Data is sent to terminal 110 via web server 118 , Internet 112 and router 106 .

The range-of-motion angle creation program of the terminal 110 receives the data transmitted by the DB server 116 . The range-of-motion angle creation program compiles a graph of the maximum range-of-motion angle versus date and a date-by-date data list for each band ID from the received data, and edits them so that they can be printed by a printing machine connected to the terminal 110. (Fig. 11). Note that the range-of-motion angle creation program can also upload the measurement results to a web server or cloud and display them on any terminal via the network.

Here, among the received data, the data of the latest date are ranked by three predetermined numerical values A, B, and C regarding the maximum range of motion angle for each XBee-ID in advance, and the judgment rank is determined by the maximum range of motion. Display with angle versus date graph.

These tabulated results are generated by the range of motion angle creation program, and in addition to being printed by a printer, a web page for displaying the tabulated results is generated by a web server and viewed with a web browser installed on a personal computer used by the user, or by the user You may enable it to browse by the browser of a used smart phone or tablet, or a web application. In this case, when the user using the present invention completes all the measurements of the day using this system and touches his/her band ID to the IC tag antenna 110A connected to the terminal 110, the terminal 110 is linked to display a selection button for printing with a printing machine (not shown) or displaying a QR code (registered trademark). When the user selects the print button, the printer connected to the terminal 110 prints.

On the other hand, when the QR code (registered trademark) display is selected, the range-of-motion angle creation program automatically generates a QR code (registered trademark) that means an address unique to the user, and the terminal 110 is connected to display the QR code on a monitor (not shown). (registered trademark) is displayed. Also, the range of motion angle creation program uploads the measurement results to the web page corresponding to this QR code (registered trademark). For this reason, users who have a QR code (registered trademark) displayed can scan the QR code (registered trademark) with their own mobile terminal personal computer, etc., and display the web page displayed with the QR code (registered trademark). It is also possible to display the measurement results on the screen of a mobile terminal PC or the like.

It is also possible to issue an ID and password to the user in advance, display a web page for each user, and display the measurement results on that web page.

On the other hand, a method of obtaining with a trigonometric function will be described.

Then, when the U-shaped handle 24 is fully lowered, the weight 46 rises to the highest position. The position of this weight 46 is the 0-degree reference point, and the range of motion angle θ=0°. The arm 18 rotates around the rotation axis 16 (point O). Here, let l be the distance between MO (FO).

Subsequently, when the person to be measured holds the U-shaped handle 24 while relaxing both hands and shoulders, the U-shaped handle 24 and the arm 18 rise as the weight 46 descends, and as a result, the scapula and shoulder The joints, spinal column, and the trapezius, latissimus dorsi, rhomboids, erector spinae, deltoids, and other muscles connected to them are stretched.

Here, consider the case where the temperature rises to point F shown in FIG. 13 . That is, the U-shaped handle 24 is moved MF. On the other hand, the center point C2 of the counterweight 26 and the movable pulley 28 descends to C1.

As a result, the string member 30 is pulled along with the movement of the movable pulley 28, and the weight 46 is lowered by a distance n as shown in FIG.

The position of the weight 134 at the operating position MB perpendicular to the floor corresponds to the 0-degree reference point as in the other embodiments. When the legs of the footstep 152 are released, the arm 150 rotates clockwise in the direction of the paper surface of FIG. do. At this time, since the string-like member 154 passes through only the fixed pulley 136, if the distance between MB and FB is q, the movement distance of the weight in the weight device 134 is also q.

(Example 4)
Embodiment 4 according to the present invention is the application of the present invention to a hip joint 180 device 170, and the outline thereof is shown in FIGS. 16 to 19. FIG.

In the hip joint 180 device 170, stretching is performed with the legs spread in a sitting position. It acts on the hip joints and adductor muscles, increasing the range of motion of the hip joints. As a result, it is possible to improve the movement of the hip joints and lower back pain, and to improve the stoop and posture by raising the pelvis.

The hip joint 180 device 170 has a body base 172 at its bottom, a plurality of fixed pulleys at its top, and a weight frame 176 at one end on which a weight 174 is placed at its bottom. is set. Here, weight 174 is the weight in the uppermost layer, and weight 169 is the weight in the lower layer.

A back support pad frame 180 is erected adjacent to the weight frame 176, and a back support pad 178 is fixed to its front surface. A seat frame 179 is erected adjacent to the back pad 178, and a seat 182 is provided on its upper end.

Under the seat 182, there are two rotating shafts 193A, 193B. Guide rollers 188A, 188B and movable guides 184A, 184B are rotatably arranged on these 193A, 193B. Thigh sheets 186A, 186B and calf sheets 187A, 187B are respectively arranged on the top (FIG. 17).

Thigh stoppers 191A and 191B, which can come into contact with the inside of the subject's thighs, are erected on the front side of the thigh sheets 186A and 186B in FIG. 16, respectively. Lower leg stoppers 190A and 190B, which can come into contact with the inside of the shin of the person being measured, are erected on the front side of the lower leg sheets 187A and 187B as viewed in FIG.

Next, the configuration below the seat 182 will be described with reference to FIGS. 17 to 19. FIG. The seat 182 is supported by the back seat frame 181 on the weight 174 side and by the seat frame 179 on the front side. The right rotating shaft 193A of the seat frame 179 is rotatably connected to the guide roller 188A, the movable guide portion 184A, the sector plate 185, and the locking plate 209 from above.

On the other hand, the left rotating shaft 193B of the seat frame 179 is rotatably connected to the guide roller 188B and the movable guide portion 184B from above.

Two synchronizing wires 197 for synchronizing the two guide rollers 188A and 188B and the rotary shafts 193A and 193B connect the guide rollers 188A and 188B in a figure eight shape.

Further, the weight wire 194 connected to the weight 174 has its end fixed to the side surface of the fan-shaped plate 185 , and the direction of the weight 174 is controlled by the fixed pulley 183 supported by the pulley support portion 177 extending from the back seat frame 181 . It changes direction, passes under the weight 174, changes direction vertically upward by a fixed pulley 195 provided on the back surface of the weight 174, and is provided on a top frame supported by the weight frame 176 and is fixed by a fixed pulley 198 (not shown). It is connected to the weight 174 by changing the direction vertically downward.

A lever wire 175 connected to a drive lever 199 that drives the movable guide portion is fixed in the vicinity of the rotating portion of the drive lever 199 that is rotatably connected to the weight frame 176 . The direction is changed vertically downward by a fixed pulley 189 in the setting portion, the direction is changed horizontally by a fixed pulley 171 connected to the main body base 172 and set up near the back seat frame 181, and further horizontally adjacent. It is turned and connected to the locking plate 209 by a fixed pulley 173 arranged in the . The locking plate 209 is provided with locking projections 211 for locking the fan-shaped plate 185 .

The operation of the hip joint 180 device 170 according to the present invention will now be described. In the hip joint 180 device 170 , the person to be measured sits on the seat 182 with the back in contact with the back pad 178 . At this time, both legs of the person to be measured are placed with the right leg on the thigh sheet 186A and the lower leg sheet 187A, and the left leg on the thigh sheet 186B and the lower leg sheet 187B. 16, the thigh seat 186A and the lower leg seat 187A, and the thigh seat 186B and the lower leg seat 187B are arranged on both sides of the seat 182, respectively. Also, at this time, the weight 174 is in a landed state, and the range of motion angle for measuring this state is 180°.

On the other hand, when both legs are closed at the front, the stopper 192 projecting from the upper front frame of the thigh stopper 191A in FIG. 16 comes into contact with the upper front frame of the thigh stopper 191B in FIG. , the angle formed by the movable guide portion 184A and the movable guide portion 184B is opened by 5°, and the weight 174 is raised to the highest position. The position of the weight 174 when this angle is 5° corresponds to the 0-degree reference point in other embodiments.

Therefore, from an angle of 5° to 180°, the weight 174 urges the legs to open the legs, and the transmission/reception unit detects the moving distance of the weight 174 at that time.

Specifically, when the weight 174 descends from a high position, the fan-shaped plate 185 rotates clockwise from above in conjunction with the weight wire 194, and the movable guide portion 184A also rotates clockwise according to the rotation. As a result, the thigh seat 186A and the lower leg seat 187A also rotate clockwise, and the thigh stopper 191A and lower leg stopper 190A press the thigh and lower leg of the right leg to open the right leg. to support.

On the other hand, when the right rotating shaft 193A rotates clockwise, the guide roller 188A also rotates clockwise from above. As a result, the two synchronizing wires 197 are coupled in a figure-of-eight shape to synchronously rotate the guide roller 188B counterclockwise. Therefore, the left rotating shaft 193B also rotates counterclockwise, and the movable guide portion 184B also rotates counterclockwise according to the rotation, and as a result, the thigh seat 186B and the lower leg seat 187B also rotate counterclockwise, A stopper 191B and a lower leg stopper 190B press the thigh and lower leg of the left leg to assist in the direction of opening the left leg. As a result, the legs are opened to the point where the range of motion angle between the legs becomes 180 degrees, and the angle of the range of motion is measured from the distance the weight has moved as a result. Through the above steps, the hip joint 180 device 170 is used to move the hip joint and adductor muscles, and the range of motion angle of the hip joint 180 device 170 can be objectively measured.

であるから、

で表現される（円弧算出方法）。 Here, if the radius AO of the sector plate 185 is s, the joint range of motion angle AOB is 2θ, and the movement distance of the weight wire 194 is r, the relationship between them can be obtained by the formula for calculating the arc length of the sector plate 185.

Because

(circular arc calculation method).

When the lever 199 is pushed vertically downward, the lever wire 175 is pulled to rotate the locking plate 209 counterclockwise in FIG. Therefore, the right rotating shaft 193A, the guide roller 188A, and the movable guide portion 184A rotate counterclockwise in FIG. Also, the guide roller 188B is synchronously rotated clockwise in FIG. As a result, the left rotating shaft 193B, the guide roller 188B, and the movable guide portion 184B rotate clockwise in FIG. As a result, the movable guide portion 184A and the movable guide portion 184B are closed in the closing direction, and at the same time the weight wire 194 pulls the weight 174 so that the weight 174 is lifted.

Although the weight wire 194 is wound around the fan-shaped plate 185 in this embodiment, it goes without saying that the same effect can be obtained by winding the weight wire 194 using guide rollers. In addition to the arc calculation method, the angle can also be calculated by the proportional division calculation method as in the first embodiment.

(Example 5)
A fifth embodiment according to the present invention is an application of the present invention to a hip joint motion device 200, and its outline is shown in FIGS. 20 and 21. FIG.

It acts on the hip joint, the abductor muscle group, the adductor muscle group, the quadriceps femoris muscle, the hamstring muscle, etc., and the range of motion angle of the hip joint is expanded. As a result, movement of the hip joint, improvement of low back pain, and improvement of posture can be achieved.

In the hip joint motion device 200, a weight 206 is arranged on a weight frame 204 having a fixed pulley at the top, and a main body base 202 extends at the bottom in a direction perpendicular to the weight 206, and is fixed to a side base 201 at its tip. supported by A rotating rod support frame 208 is erected on the main body base 202, and Y-shaped frames 220A and 220B are provided on the top thereof to support parallel bars 222A and 222B. The rotating rod support frame 208 is also connected to and supported by the weight frame 204 by the rod horizontal frame 214 .

A rod fixing disk 212 is arranged above the rotating rod support frame 208 and below the Y-shaped frames 220A and 220B, and a rotating rod 216 is rotatably fixed to a rotating shaft 215 at the center thereof. A counterweight 218 is provided at one end of the rotating rod 216, and a projecting rod projecting vertically is provided at the other end, and a pad 224 is placed on the projecting rod. This rod fixing disk 212 has a wire winding function, and fixed pulleys 210A and 210B provided directly below the rod fixing disk 212 direct the direction of the wire vertically downward. The fixed pulley 226 provided changes the direction of the wire to the direction of the weight 206 in the horizontal direction, and the fixed pulley (not shown) provided on the back side of the weight 206 makes the wire vertically upward and the fixed pulley (not shown) on the upper end of the weight frame 204. At , the direction of the wire is changed vertically downward and connected to the weight 206 to apply a tensile force. The left and right fixed pulleys 210A and 210B are provided one by one, and the left and right fixed pulleys 210A and 210B are selectively used depending on the rotating direction of the rotating rod 216. FIG. A plurality of position adjusting holes 219 are arranged in an arc shape in the rod fixing disk 212 . The position of the rotating rod 216 is fixed and the height position of the pad 224 is adjusted by replacing the tip of the rotating rod knob 217 provided on the rotating rod 216 with an arbitrary position adjustment hole 219 selected. It should be noted that the weight of the uppermost layer is weight 206 and the weight of the lower layer is weight 207 .

The operation of the hip joint motion device 200 according to the present invention will now be described. As shown in FIG. 20, the hip joint motion device 200 defines a state in which the pad 224 is raised around the rotation axis 215 and the weight 206 is positioned at the bottom as the start position.

On the other hand, as shown in FIG. 21, the rotating rod 216 is rotated to be oriented vertically downward, the pad 224 is lowered to the lowest position, and the weight 206 is positioned at the upper position. is the 0 degree reference point.

The height of the starting position of the pad 224 is determined by replacing the rotary rod knob 217 with one of the position adjustment holes 219 .

From here, when the person to be measured puts the leg to be measured on the pad 224 and rotates the rotating rod 216, the leg rises and the displacement of the weight is measured, whereby the range of motion angle of the hip joint can be measured. can. The highest position of the weight 206 is the position shown in FIG. It is determined whether the rotation is counterclockwise or clockwise by replacing the tip of the rotary rod knob 217 with the selected position adjustment hole 219 .

After the clockwise and counterclockwise rotations are determined and the position of the pad 224 is set, the leg to be measured is placed on the pad 224 . The pad 224 is temporarily lowered by the weight of the leg, but when the leg is relaxed, the weight of the weight 206 raises the pad 224 as well. 21, the weight 206 is at the highest position, and as the weight 206 descends due to gravity, it is pulled by the wire, and the rod fixing disk 212 rotates around the rotation axis 215 to rotate the rotation rod. 216 also rotates and pad 224 rises clockwise to the position of FIG. Weight 206 is then lowered to the lowest point. The angle is measured by the difference between the lowest point of the weight 206 and the 0 degree reference point. Others are carried out in the same manner as in Example 1.

であるから、

で表現される。なお、角度の算出方法は円弧算出方法の他に実施例１同様に按分算出方法でも算出可能である。 Here, if the radius AO of the rod fixing disk 212 is t, the 0 degree reference point is B, and the raised position of the rod fixing disk 212 when the pad is raised to the maximum is A, then the joint range of motion angle AOB is θ and the moving distance of the weight wire is u.

Because

is represented by In addition to the arc calculation method, the angle can also be calculated by the proportional division calculation method as in the first embodiment.

In the present invention, infrared diodes or light-emitting diodes and photosensors are used as a method for measuring the moving distance of the weight, but in addition to this, an ultrasonic method that measures the time it takes for an ultrasonic wave to be irradiated, reflected, and returned can also be used. can do

In addition, a laser light ranging method can be used in which a laser light is split by a splitter, part of the laser light is irradiated onto a measurement object, and the phase difference between the reflected laser light and the original laser light is measured. Infrared laser light can also be used as the laser light.

It is also possible to apply a magnet ranging method in which a coil is arranged on the sensor side, a magnet is provided on the weight side, and the magnet is moved along the coil to detect the position by an induced current.

Furthermore, by adopting a motion capture technique, the user attaches light-emitting elements or markers to his body, especially his arms and legs, at regular intervals, and cameras are placed behind and to the side, allowing the user to move freely regardless of the position of the weight. It is also possible to measure the position and rotation direction of the joint from the position of the arm or leg, and the joint range of motion angle from the movement speed.

In addition, by attaching a light-emitting body to the movable part and the rotating shaft of the main unit instead of the user's body and measuring the movement of the pad or the like of the main unit with a measuring device, the first position of the movable part and the first position can be determined. The angle formed by the first position, the rotation axis, and the second position can also be measured by the measuring section at a second position of the movable section that is different from the position of .

An example of a motion sensor method can be done optically using a camera or markers. In addition, it can be done inertially using accelerometers, angular velocimeters, gyros or geomagnetometers. Note that the inertial measurement unit using an accelerometer, angular velocity meter, gyro, or geomagnetometer may be connected to any one of the movable unit, the rotating shaft, and the body. In addition, a magnetic system using a magnetic field generator or a coil can also be used. Furthermore, it can also be realized mechanically using a potentiometer.

In addition, it is also possible to take a picture with a camera and detect the position from the image recognition function without adding a light-emitting body to the user or the main device.

Further, in the present invention, a weight is used as a means for generating a tensile force on the wire, and gravity is used. can also occur.

So far, all of the explanations have been about devices in which the rotating shaft is supported by a support, but by installing a sensor that measures the angle of the gripper in the load-adjustable hand gripper, the rotating shaft is not supported by the support. It goes without saying that a device can also be provided.

Alternatively, the movable body includes a rotating shaft without a supporting portion, a movable portion that is rotatably connected to the rotating shaft and moves together with a part of the body, and a measuring portion that measures the rotation angle of the movable portion. At a first position of the portion and a second position of the movable portion different from the first position, the angle formed by the first position, the rotation axis, and the second position is defined as the It can also be measured by the measuring unit.

On the other hand, in the process of developing a conventional muscle training machine or stretching machine, the inventors found that it is possible to quantify the range of motion of joints by displaying the angle while operating these machines. I figured it out.

Until now, it has been physically possible to measure the angle of a joint by directly applying a protractor to the joint during training, but this is not easy because the fulcrum is not fixed. It was necessary to temporarily stop the movement of the body, and a third party was required to measure the angle, so it was not easy to adopt as a practical method.
