[Table 1]

According to an embodiment, as shown in Table 1, 25 feature points in the body may be specified through the 3D sensor unit 110 . These characteristic points are as shown in FIG. 4 . Referring to FIG. 3 , in step S110 , the controller 180 determines a region and motion to measure a joint range of motion of a patient, for example, a patient to be treated.

Table 2 below is a table of some of the measurement sites according to the embodiment of the present invention. In Table 2, each of the left and right shoulders, arms, hips and knees, and only nine including the head in the center are arranged, but not limited thereto, and through the 3D sensor unit 110 as shown in Tables 1 and 4 Any feature point from which three-dimensional coordinates are detected may be a measurement site.

[Table 2]

In addition, each measurement site can measure the joint range of motion according to five types of measurement movements including flexion, extension, adduction, abduction, and rotation, respectively. . An example of flexion and extension of the right hip and adduction of the left hip is shown in FIG. 6 . Accordingly, when the measurement site and the measurement motion are determined, the operation to be taken by the patient when measuring, that is, the measurement operation is determined. Accordingly, the controller 180 provides a guide image through the audio unit 140 and the display unit 160 in step S120 . The guidance image is an image representing an action to be taken, that is, a measurement action, to be taken by a subject to be measured, corresponding to a region and movement to be measured during measurement. The patient may perform an operation according to the measurement operation through the guidance image.

When the patient takes a measurement operation according to the guidance image, the controller 180 measures the joint range of motion according to the measurement site and the measurement movement in step S130. Step S130 will be described in more detail with reference to FIGS. 4, 5 and 6 . In step S130 , the controller 180 first determines a corresponding two-dimensional coordinate plane according to a region and motion (measurement region and measurement motion) for which a joint range of motion is to be measured (see FIG. 5 ), and a plurality of feature points ( FIG. 4 ). reference), the fixed point a0, the reference point a1, and the motion point a2 are specified (refer to FIG. 6). The coordinate plane is determined according to the measurement motion with reference to FIGS. 5 and 6 . As an example, referring to FIGS. 5 (A) and 6 (A) and (B), when the measured motion is extension, the yz coordinate plane is used for the measured motion extension of the right hip. . As another example, referring to FIGS. 5B and 6C , when the measurement motion is an adduction, the x-y coordinate plane is used for the measurement motion adduction.

Referring to Table 2, FIGS. 4 and 6 , the reference point a1 and the motion point a2 are determined according to the measurement site. As an example, referring to Table 2, FIGS. 4 and 6 (A) and (B), if the measurement site is the right hip, the feature point (Hip_Right) representing the right hip becomes the reference point (a1), and represents the right knee The feature point Knee_Right becomes the motion point a2. As another example, referring to Table 2, FIGS. 4 and 6 (c), if the measurement site is the left hip, the feature point (Hip_Left) representing the left hip becomes the reference point (a1), and the feature point (Knee_Left) representing the left knee This becomes the motion point a2.

The fixed point a0 is determined according to the determined coordinate plane and the reference point a1 and the motion point a2. The fixed point a0 refers to a point vertically spaced apart from the reference point a1 on the determined coordinate plane by a distance equal to the distance between the reference point a1 and the motion point a2 in the direction of the floor.

As an example, referring to Table 2, FIGS. 4 and 5 (A) and 6 (A) and (B), the feature point (Hip_Right) and the motion point (a2) representing the right hip as the reference point (a1) are When the distance between the feature points (Knee_Right) representing the right knee is 30 (cm), the fixed point (a0) is a point vertically spaced from the reference point (a1, Hip_Right) by 30 (cm) in the direction of the floor on the yz coordinate plane. . As another example, referring to Table 2, FIGS. 4, 5 (B) and 6 (C), the feature point (Hip_Left) representing the left hip as the reference point (a1) and the left knee as the exercise point (a2) are shown When the distance between the feature points Knee_Left is 30 (cm), the fixed point a0 is a point vertically spaced from the reference point (a1, Hip_Left) by 30 (cm) in the floor direction on the yz coordinate plane. As described above, when the two-dimensional coordinate plane and the fixed point a0, the reference point a1, and the motion point a2 are specified, the controller 180 controls the fixed point a0, the reference point a1, and the motion. From the three-dimensional coordinates of the point (a2), the two-dimensional coordinates of the fixed point (a0), the reference point (a1), and the moving point (a2) are derived according to the previously determined two-dimensional coordinate plane, and using the derived two-dimensional coordinates, the following Calculate the two-dimensional measurement value of the joint range of motion according to Equations 1, 2 and 3.

Equation 1

Equation 2

Equation 3

Here, denotes a two-dimensional measured value. The three-dimensional measurement value of the joint range of motion means a value calculated using vectors derived from the two-dimensional coordinates of the fixed point (a0), the reference point (a1), and the motion point (a2). Also, v1 is a vector in a direction from the reference point a1 to the fixed point a0 on the two-dimensional coordinates. And v2 represents a vector in a direction from the reference point a1 to the motion point a2 on the two-dimensional coordinates. In addition, Equation 1 is an equation when the angle does not exceed 180 degrees, and Equation 2 shows an equation when the angle exceeds 180 degrees.

Meanwhile, the controller 180 calculates a three-dimensional measured value of the joint range of motion according to the following Equation 4 by using the three-dimensional coordinates of the fixed point a0, the reference point a1, and the motion point a2.

Equation 4

represents the three-dimensional measurement of the joint range of motion. The three-dimensional measurement value of the joint range of motion refers to a value calculated using a vector derived from the three-dimensional coordinates of the fixed point (a0), the reference point (a1), and the motion point (a2). Also, k1 is a vector from the reference point a1 to the fixed point a0 on the three-dimensional coordinates. And k2 represents a vector from the reference point (a1) to the motion point (a2) on the three-dimensional coordinates. The three-dimensional measured value of the joint range of motion is used to decide whether to use the two-dimensional measured value of the joint range of motion. A more detailed description of this is as follows. As described above, the coordinate plane is determined according to the movement to be measured (measured movement) for the joint range of motion. Accordingly, the patient to be treated must perform an operation along the coordinate plane according to the guidance image. For example, referring to FIGS. 5 (A) and 6 (A) and (B), when the measurement movement is flexion or extension, the measurement movement of the right hip must be performed on the yz coordinate plane. do. That is, the patient must move the leg, that is, the thigh from the right hip to the right knee, from the front side or the back side with respect to the patient. However, the patient does not perform only the bending (flexion) or extension (extension) motion, and other motions, that is, the vowel (adduction), abduction (abduction) or rotation (rotation) motion can be mixed and performed. As such, when other motion (adduction, abduction, rotation) components are excessive, it is inappropriate to use the measured value of the corresponding joint range of motion for treatment.

Accordingly, when the difference between the three-dimensional measured value and the two-dimensional measured value of the joint range of motion exceeds a preset value, the controller 180 erases the two-dimensional measured value and does not use it. On the other hand, if the difference between the three-dimensional measured value and the two-dimensional measured value is less than a preset value, the two-dimensional measured value is determined as the measured value of the joint range of motion. Meanwhile, according to an embodiment of the present invention, the two-dimensional measured value may be corrected using the previously measured measured value of the joint range of motion. The patient performs a measurement operation through the guidance image, and the controller 180 guides the patient to slowly follow the measurement operation when the patient performs the measurement operation through the guidance image. Accordingly, when the measurement operation is, for example, flexion, the patient gradually proceeds to bring the thigh closer to his/her body at a speed within a predetermined range. Therefore, the change in the measured value of the joint range of motion of the measurement site according to the measurement operation is made within a predetermined range. Therefore, a change in the previously measured joint motion range measurement value is also made within a predetermined range. Accordingly, the controller 180 may correct the two-dimensional measured value using the previously measured measured value of the joint motion range. Accordingly, the controller 180 corrects the current measured value by applying a weight to the correction value obtained by correcting the previously measured two-dimensional measured value of the predetermined number of joint motion ranges and the current two-dimensional measured value.

For example, referring to FIG. 7 , it is assumed that three previous values are used. When the two-dimensional measurement value of the joint range of motion is rn-3, rn-2, and rn-1 in chronological order, the controller 180 corrects it according to an embodiment of the present invention to Rn-3, Rn-2, Rn- Assume that it is corrected to 1. Also, it is assumed that the current two-dimensional measurement value is rn. Then, the controller 180 corrects the current two-dimensional measurement value according to Equation 5 below.

Equation 5

Here, w1, w2, and w3 denote weights, and may have values of 0.3, 0.3, and 0.4, respectively. After measuring and correcting the joint range of motion in the same way as described above and calculating the measured value of the range of motion, the controller 180 determines whether the preset measurement time has expired in step S140, and if it has not expired, The measured value is stored in the storage unit 170, and steps S130 and S140 described above are repeated. On the other hand, when the preset measurement time has expired, the controller 180 selects the maximum value among the plurality of previously stored measurement values as the joint motion range in step S160.

Meanwhile, according to another embodiment of the present invention, when the joint range of motion is restricted due to pain, the range of motion of the joint at the moment of pain may be measured. This can be an important diagnostic data in the treatment of pain. Therefore, the present invention proposes a method for measuring the joint range of motion at the moment of pain. According to another embodiment of the present invention, the moment when pain occurs during the measurement operation is specified through the patient's voice, and the joint range of motion at that moment is measured. 8 is a flowchart for explaining a method for measuring a joint range of motion according to another embodiment of the present invention.

Referring to FIG. 8 , in step S210 , the controller 180 determines a part and motion (measurement part and measurement motion) for measuring a joint range of motion of a patient, for example, a patient. Since this step S210 is the same as step S110 of FIG. 3 , a more detailed description will be omitted.

When the measurement site and the measurement motion are determined, an action to be taken by the patient when measuring, that is, a measurement action is determined. Accordingly, the controller 180 provides a guide image through the audio unit 140 and the display unit 160 in step S220. The guide image is an image representing an action to be taken, ie, a measurement action, to be taken by a subject to be measured, corresponding to a region and motion to be measured during measurement. In addition, according to another embodiment of the present invention, the guide image includes content for slowly performing a measurement exercise for the measurement site and to make a sound when pain occurs during the measurement movement.

When the subject to be treated takes a measurement operation according to the guidance image, the controller 180 continuously measures the joint range of motion according to the measurement site and the measurement movement in step S230. Since this step S230 is the same as step S130 of FIG. 3 , a detailed description thereof will be omitted. As such, while continuously measuring the joint range of motion, the controller 180 determines whether the preset measurement time has expired in step S240, and if not, proceeds to step S250.

The controller 180 receives the audio signal through the audio unit 140 in step S250 and determines whether the received audio signal is an audio signal complaining of pain of a patient to be treated. The audio signal complaining of pain may include, for example, a moaning sound due to pain, a voice saying 'it hurts', and the like. According to an embodiment, a voice recognizer for receiving an audio signal of a subject to be treated and recognizing and classifying a voice may be used to determine whether the received audio signal is caused by pain. Such a voice recognizer may include, for example, a dictionary database in which a voice dictionary, a pronunciation dictionary, and the like are stored, and a recognition network for voice recognition. Accordingly, it is possible to determine whether the received audio signal is caused by pain by learning, for example, a moaning sound due to pain or a voice saying 'it hurts'.

In addition, the speech recognizer may use an artificial neural network. At this time, according to an embodiment of the present invention, it is preferable to use a convolutional neural network (CNN) among artificial neural networks. A convolutional neural network includes an input layer, a hidden layer, and an output layer, and the hidden layer includes at least one convolution layer, at least one pooling layer, and a full a fully-connected layer. Accordingly, the controller 180 can train the artificial neural network through a backpropagation algorithm by inputting a moaning sound due to pain, a voice saying 'it hurts', etc. to the input layer of the artificial neural network as learning data. .

After being sufficiently learned, the controller 180 inputs an audio signal input through the audio unit 140 into the artificial neural network 300, and the audio signal input through the artificial neural network 300 outputs an audio signal that complains of pain. It can be determined whether or not As a result of the determination in step S250, if the input audio signal is an audio signal complaining of pain, the controller 180 proceeds to step S260, and stores the measured value calculated at the point in time when the pain identified through the audio signal occurs in the storage unit 170 ) is stored in In this way, the controller 180 repeats steps S230 to S260 before the preset measurement time expires. On the other hand, the controller 180 determines whether the preset measurement time has expired in step S240, and if it has expired, proceeds to step S270, and moves the minimum value among the plurality of measured values stored earlier (S260) to the maximum in case of pain. It is determined by the range of possible joint motion.

Meanwhile, according to another embodiment of the present invention, when the joint range of motion is restricted due to pain, it is possible to measure the range of motion of the joint at the moment of pain. This can be an important diagnostic data in the treatment of pain. However, it is difficult to perform the measurement according to the size of the pain to stop the measurement operation and measure the joint range of motion at that moment when the patient experiences pain on their own, and the result is also inaccurate. Therefore, the present invention can use facial expressions to specify a moment when pain occurs during a measurement operation, and measure a joint range of motion at that moment. 9 is a flowchart for explaining a method for measuring a joint range of motion according to another embodiment of the present invention.

Referring to FIG. 9 , in step S310 , the controller 180 determines a part and motion (measurement part and measurement motion) for measuring a joint range of motion of a patient to be treated, for example, a patient. Since this step S310 is the same as step S110 of FIG. 3 or step S210 of FIG. 8, a more detailed description will be omitted. In this way, when the measurement site and the measurement motion are determined, the operation to be taken by the patient during measurement, that is, the measurement operation is determined. Accordingly, the controller 180 provides a guide image through the audio unit 140 and the display unit 160 in step S320 . Since this step S320 is the same as step S120 of FIG. 3 or step S220 of FIG. 8, a more detailed description will be omitted. When the subject to be treated takes a measurement operation according to the guidance image, the controller 180 continuously measures the joint range of motion according to the measurement site and the measurement movement in step S330.

Since step S330 is the same as step S130 of FIG. 3 or step S230 of FIG. 8, a more detailed description will be omitted. As such, while continuously measuring the joint range of motion, the controller 180 determines whether the preset measurement time has expired in step S340, and if not, proceeds to step S350. The controller 180 determines whether the facial expression of the patient is changed due to pain by observing the facial expression of the patient through the facial image of the patient taken through the camera unit 130 in step S350. According to an embodiment of the present invention, an artificial neural network may be used to observe the facial expression of the patient to be treated and to detect that the facial expression of the patient is changed due to pain.

At this time, according to an embodiment of the present invention, it is preferable to use a convolutional neural network (CNN) among artificial neural networks. A convolutional neural network includes an input layer, a hidden layer, and an output layer, and the hidden layer includes at least one convolution layer, at least one pooling layer, and a full a fully-connected layer. Accordingly, the controller 180 can train the artificial neural network through a backpropagation algorithm by inputting a photograph or image of a person's face in the case of pain in the input layer of the artificial neural network as learning data. can After being sufficiently learned, the controller 180 inputs the facial image of the subject taken through the camera unit 130 into the artificial neural network 300, and the artificial neural network 300 outputs the facial expression of the subject to pain. It can be determined whether or not it is changed by As a result of the determination in step S350, when it is determined that the facial expression of the patient is changed due to pain from the facial image of the patient taken through the camera unit 130, the time when the facial expression is changed is determined as the time when the pain occurs, and the control unit Step 180 proceeds to step S360, and stores the measured value calculated at the point in time when pain occurs in the storage unit 170 . In this way, the controller 180 repeats steps S330 to S360 before the expiration of the preset measurement time.

On the other hand, the controller 180 determines whether the preset measurement time has expired in step S340, and if it has expired, proceeds to step S370, and moves the minimum value among the plurality of measured values stored above (S360) to the maximum. determined by range. On the other hand, the various methods according to the embodiment of the present invention described above may be implemented in the form of a program readable through various computer means and recorded in a computer readable recording medium. Here, the recording medium may include a program command, a data file, a data structure, etc. alone or in combination.

Here, the configuration of the second stopper part 1340 is configured to correspond to the configuration of the above-described first stopper part 1240 and may be positioned to be symmetrical to each other.

5 and 6 are views conceptually illustrating the principle of adjusting the opening angle and the bending angle of the knee joint by the second stopper part 1340 and the first stopper part 1240. Referring to this, the first of the present invention The operation of the angle adjusting unit 1200 and the second angle adjusting unit 1300 will be examined respectively.

First, FIG. 5 shows the principle that the unfolding angle is adjusted by the second angle adjusting unit 1300 . Referring to the drawings, the second angle adjusting unit 1300 may be configured to adjust the rotation angle of the fourth frame 1122 so that the fourth frame 1122 is rotated only within a set unfolding angle.

Specifically, the second angle adjusting unit 1300 is rotated in conjunction with the second stopper unit 1340 according to the rotation of the fourth frame 1122, and the rotation of the fourth frame 1122 at this time is the second Its rotation is restricted by the stopper unit 1340 . This is because the fourth frame 1122 interferes with the second frame 1112 as the second stopper unit 1340 moves in the clockwise direction according to the unfolding rotational operation as shown, thereby limiting movement.

Meanwhile, in the present invention, the second angle adjusting unit 1300 may be configured to adjust the unfolding angle range by adjusting the position of the second stopper unit 1340 . That is, as shown, the state in which all the knee joints are stretched to the extent that the fourth frame 1122 and the second frame 1112 are arranged in a straight line is referred to as a2, and the state in which the knee joint is limited so that it can be stretched only within the set angle. When is a1, the unfolding angle may be adjusted by adjusting the position of the second stopper unit 1340 . The second stopper part 1340 indicated by a hidden line in the drawing schematically shows the position before unfolding. As shown, the second stopper part 1340 moves forward clockwise as the position moves forward in the clockwise direction, the fourth frame ( 1122), it can be seen that the unfolding angle is limited.

On the other hand, the position of the second stopper unit 1340 can be adjusted by the control unit 1500 , and for this purpose, the control unit 1500 sets the second gear 1320 by rotating the second motor 1310 . rotate according to the rotation angle, and the positions of the second rotation gear 1330 and the second stopper part 1340 are changed by the rotation of the second gear 1320 so that the rotation angle of the second frame unit 1120 is adjusted. can be configured.

Next, the principle of adjusting the bending angle will be described. Referring to FIG. 6 , the first angle adjusting unit 1200 may be configured to adjust the rotation angle of the second frame 1112 so that the second frame 1112 rotates only within a set bending angle.

In detail, the first angle adjusting unit 1200 is rotated in conjunction with the first stopper unit 1240 according to the rotation of the second frame 1112, and the rotation of the second frame 1112 at this time is the first The rotation is restricted by the stopper unit 1240 . This is because the movement of the second frame 1112 is limited as the first stopper unit 1240 moves in a clockwise direction according to the bending operation and then comes into interference contact with the fourth frame 1122 as shown.

In the present invention, the first angle adjusting unit 1200 may be configured to adjust the bending angle range by adjusting the position of the first stopper unit 1240 like the first angle adjusting unit 1200 . Referring to the drawings, when a state in which the second frame 1112 is bent in a horizontal state is referred to as b2, and a state in which the knee joint is bent only within a set angle is referred to as b1, the position of the first stow is adjusted. The bending angle can be adjusted. At this time, the first stopper part 1240 indicated by the hidden line in the drawing schematically shows the position before each bending, and as the position of the first stopper part 1240 is moved forward in the clockwise direction as shown, the second frame ( 1112), it can be seen that the bending angle is limited.

At this time, the position of the first stopper unit 1240 may be adjusted by the control unit 1500 , and for this purpose, the control unit 1500 rotates the first motor 1210 to set the first gear 1220 . Rotate according to the rotation angle, and the positions of the first rotation gear 1230 and the first stopper part 1240 are changed by the rotation of the first gear 1220 so that the rotation angle of the first frame unit 1110 is adjusted. can be configured.

Meanwhile, in , the first stopper part 1240 and the second stopper part 1340 contact and interfere with the side surfaces of the second frame 1112 and the fourth frame 1122 to restrict their movement, but , this is an embodiment, if the movement of the first stopper unit 1240 and the second stopper unit 1340 can be limited, the restraint target is varied according to the design other than the second frame 1112 and the fourth frame 1122 Of course, it is of course possible to design by setting the bending angle range and the unfolding angle range in various ways. In addition, although FIG. 5 shows the principle that only the second angle control unit 1300 is adjusted, and FIG. 6 shows the principle that only the first angle control unit 1200 is adjusted, although not shown, the first angle control unit 1200 and the The two angle adjusting unit 1300 may be adjusted together to adjust the bending angle and the unfolding angle.

Hereinafter, the control unit 1500 will be described.

At this time, the control unit 1500 compares the maximum value of the actual bending angle of the subject and the average range of the amount of change in the bending angle with the rotation angle of the first frame unit 1110 set, and the actual knee joint bending degree of the subject does not reach the set value. If not, it is judged that the recovery of the subject is slow, and the set value can be extended without changing to the next stage.

On the other hand, the control unit 1500, compared with the actual knee bending angle and the set rotation angle, the actual knee bending angle maximum value of the subject corresponds to the set rotation angle and the number of times of reaching the maximum value corresponds to the set number of times, the preset rotation Depending on the angle, the rotation angle is controlled through the first angle adjusting unit 1200 . On the other hand, at this time, the rotation angle progress step can be adjusted according to the number of times the actual maximum knee bending angle has been reached. can be changed to

Next, the controller 1500 compares the maximum value of the actual unfolding angle of the subject and the average range of the amount of change in the unfolding angle with the rotation angle of the set second frame unit 1120, and the actual degree of extension of the knee joint of the subject is set to the set value. If not, it is judged that the recovery of the subject is slow, and the set value can be extended without changing to the next step.

On the other hand, the controller 1500 compares the actual knee extension angle and the set rotation angle, and the maximum value of the actual knee extension angle of the subject corresponds to the set rotation angle and the number of times of reaching the maximum value falls within the preset number of rotations. Depending on the angle, the rotation angle is controlled through the second angle adjusting unit 1300 . At this time, if the number of times of reaching the maximum value of the actual knee bending angle exceeds the set number range, it is determined that the recovery is fast, and the rotation angle can be increased to change to the next step.

On the other hand, the control unit 1500, in controlling the bending angle and the unfolding angle of the knee as described above by individually controlling the first angle adjusting unit 1200 and the second angle adjusting unit 1300, respectively, the knee bending angle and Each rotation angle can be set in consideration of the relative angles by interlocking the unfolding angles with each other.
