Description

Apparatus and method for diagnosing physical malformation syndrome using plantar pressure and body motion information

The present invention relates to an apparatus and method for diagnosing physical malformation syndrome using plantar pressure and body motion information. In particular, the plantar pressure and body motion information of natural gait are collected by synchronizing time, and according to the walking process alone and associated analysis. The present invention relates to an apparatus and method for diagnosing physical malformation syndrome using plantar pressure and body motion information, which enables accurate diagnosis of malformation syndrome by enabling to accurately grasp characteristics of a walking operation.

The human body is affected and adapts to a variety of things, such as gravity, posture, environment, physical activity, injury, and repetitive movement. Among these, it is very important that human beings are constantly affected by gravity. The influence of gravity on humans makes it possible to measure the normal alignment of human beings, and on the contrary, it is said that gravity is outside the standard of normal alignment.

 One of our body's functions is to maintain stability and produce efficient movements against gravity. Humans can lead to abnormal patterns of movement and dysfunction such as disease, injury, environment, emotions, body types, developmental conditions, and repetitive physical activity.

 In particular, the normal alignment of the pelvis and spinal curvature is very important to accept the effects of gravity. That is, in order to stabilize the joint supporting the weight, the gravity line must pass through the rotation axis of the joint. If the gravitational line passes abnormally through the axis of rotation of the body joint, misalignment syndrome can occur.

Misalignment syndrome occurs when the body's left and right balance is out of balance, and the feet and legs, pelvis and spine are out of balance. As a result, muscles and ligaments are asymmetrically tensioned, accompanied by abnormal gait patterns and pains, and a difference in the left and right muscle mass and strength of the body. These symptoms include differences in leg length and deformation of the foot.

 The human posture seems to be stationary, not seemingly stationary, not symmetrical back and forth, but it is constantly moving internally and forms a dynamic equilibrium state.

Therefore, when physical pressure increases in a specific area due to skeletal and muscle asymmetry and tension, structural and functional changes of the body occur. These changes include scoliosis and turtles. Turtle neck syndrome, Upper cross syndrome, Lower cross syndrome, Over-pronation of the ankle, Flat back, and the like.

Problems caused by this disorder cause additional problems, so foot problems can cause pelvic and neck problems, or pelvic problems can cause foot and neck problems. Many methods, such as the point of view of the foot, the point of view of the pelvis, and the point of view of the neck, coexist, and the criteria of the diagnosis are ambiguous because the diagnosis results may be different for each method.

Therefore, there is an increasing demand for an apparatus and method for effectively diagnosing malalignment syndrome and identifying a problem and what causes the problem. However, the methods proposed up to now are merely a simple posture analysis for orthodontic treatment or a simple measurement analysis to complement the patient to correct his or her posture during orthodontic treatment.

Korean Patent No. 10-1238094 has a walking correction plate for walking correction on a treadmill used for walking or running, and an angle correction plate for correcting foot angles to induce correct walking of pedestrians whose walking is incomplete due to obstacles. And, to provide a gait corrector to correct the correct walk through repetitive walk practice, Korean Patent Publication No. 10-2015-0113671, 'Posture Correction device and its operation method' for correcting the patient's posture For this purpose, the patient walks on the two pressure measuring scaffolds at the bottom of the treadmill, calculates the pressure, angle and walking speed of each foot, and generates the patient's walking state as a joint-based model using a 3D camera. Compared with the proposed method for providing the patient to correct the posture during walking was proposed.

In this method, only qualitative patterns of walking are calculated and compared with standard images, and only the pressure of the scaffold is analyzed to determine the degree of bias.

In order to analyze the body of the patient (testee) more effectively, Korean Patent Registration No. 10-1852655, "Spine joint musculoskeletal structure measuring device" allows the patient to rise on the pressure scaffold and the depth image (moiré, stereo camera) of the patient. After obtaining the frontal 3D geometric information by laser measurement, etc., we find the center of gravity and the center reference line and analyze the frontal image to compare the shoulder line with the ground to determine the angle or to determine the symmetry of the skeleton. .

This method uses only the most basic and superficial information of the obtained image information superficially, and is only to determine the body distortion in the static state. Therefore, it is possible to grasp the resulting state of the body (spine scoliosis), but there is a limit that practical and specific diagnosis such as the cause, related disease state, walking habits is impossible.

Therefore, in analyzing the state of misalignment syndrome in the human body, the results of the doctor's personal standards or partial measuring devices are still analyzed based on empirical rules, and therefore, high costs and time are required for the in-depth diagnosis of misalignment syndrome. It is not quantitatively managed.

Ideally, the patient's movements are accurately identified in real time through 3D sensors (stereo cameras, laser sensors, infrared sensors, time-of-flight sensors, ultrasonic sensors, etc.) to more clearly determine the symptoms of misalignment syndrome. Although it is possible to realistically measure the movement of a patient in real time and expect the quantitative accuracy of the numerical value, it is difficult to spread it to the first-line medical institutions or exercise therapy institutions, and the economical efficiency is low because it requires the management of expensive equipment and professional managers. .

That is, when generating real-time 3D information of a moving patient using a commonly used 3D sensor, the qualitative tendency is somewhat consistent, but the quantitative accuracy is error-prone, and the size of the movement of the part necessary for the actual diagnosis such as the hip or the hip joint Since 3D information is not reliable, it is difficult to use this 3D information as basic data for diagnosing malalignment syndrome in which accurate joint angle or quantitative movement is important. Therefore, in most cases, there is a limitation that the tolerance of the resultant body shape or the criterion is used only for the approximate degree of measurement.

An object of the embodiments of the present invention for improving the above-mentioned problems is plantar pressure, foot movements of the upper and lower limbs, foot pressure in the step-by-step process for walking based on information measured in real time through the foot pressure sensor and the 3D sensor of the patient walking An apparatus and method for diagnosing physical malformation syndrome using plantar pressure and movement information of the body to diagnose malformation syndrome according to the timely and more precisely by analyzing the change and movement of the musculoskeletal system related to change To provide.

An internal configuration of the gait analyzer 130 to analyze the gait of the is shown.

The illustrated configuration is a functional configuration diagram for convenience of description, and the actual components may be integrated or further subdivided, and interface units, power units, and communication units, which are not essential for understanding the present invention, are omitted. In addition, in the illustrated configuration, the control unit 139 is applied as a configuration for distinguishing each function unit and interworking them, but in practice, each function unit may be configured as a part of the control unit, and more specifically, executed through the control unit. It may be in the form of a hardware or software program. That is, the illustrated gait analyzer 130 is a computer device having one or more controllers and memory units, and each functional unit may be implemented as a software program, and some of the functional units may be implemented as hardware having separate controllers and memories.

It may include a control unit 139 for controlling.

The functional characteristics of the subject are diagnosed by identifying the walking characteristics of the examinee. In order to explain the functions of each functional part, the basic walking characteristics of the human body will be described first with reference to FIGS. 3 to 5. .

Figure 3 is an exemplary walk for explaining the steps of walking to distinguish in the embodiment of the present invention.

In general, the human body continuously produces neurologically patterned movements and movements according to the inherent angles of the joints. Walking is a continuous representation of the patterned movements of the whole body. The foot contact period) and the oleus period (foot drop period), and the lower supportive period (both foot contact) and the lower support period (one foot contact). Or seven periods.

In order to divide the walking cycle into seven periods, it is divided into eight steps as follows.

1) Initial touch: start of the stance that occurs when the foot first touches the ground at 0% of the walking cycle.

2) Take off the other toe: When the opposite foot falls off the ground at 10% of the walking cycle

3) Heel lift: When the heel is lifted from the ground at about 30% of the walking cycle

4) Reverse initial contact: When the opposite foot touches the ground at 50% of the walking cycle.

5) Toe Release: When the foot leaves the ground at 60% of the walking cycle

6) Adjacent feet: When the foot of the lower limb in the stiletto comes next to the foot of the lower leg at 73% of the walking cycle.

Tibia Vertical: When the tibia of the lower extremity in the skeletal phase is vertical at 87% of the walking cycle.

8) Initial touch: the start of the next walking cycle

In this process, the walking cycle is divided into seven periods as follows.

1) Load Reactor: when the lower limbs start to come into contact with the ground

2) Middle stance: From lifting the opposite toe to the heel rise (10-30%)

3) Terminal stance: Start when the heel rises and end when the lower leg contacts the ground (30-50%)

4) Pre-glaciator: Lifting support of the lower limbs from the initial contact of the opposite side to the toe off of the ipsilateral foot (50-60%)

5) Initial stinging period: When the toes are removed, both feet are adjacent, and the foot in the stinging period is next to the staging foot (60-73%).

6) Middle stage of declination: from the adjacency of both feet to the tibiae of the lower extremities in the phase of declination (73-87%)

7) Terminal endure angle: from the vertical position of the tibia to just before touching the heel (87-100%)

In addition, the overall movement of the human body according to the walking pattern, that is, the movement of the mass, is represented by two sinusoidal movements in the vertical line and one sinusoidal movement in the inner and outer lines as shown in FIG. 4. In the vertical line, there is mass movement in the range of about 5 cm, but the peak is the midpoint of the support of the lower extremity (30%, 80%). There are a total of 4 cm of left and right mass transfer.

Referring to FIG. 5 illustrating the foot movement pattern for the walking, the walking interval and the stride characteristics and duration of both feet can be known through the step width added with the stepwise symmetry as shown. . The forward angle is determined based on the second toe from the center of the heel.

Normally, the stride length of adults is about 72cm and the walking distance is about 10cm, and the forward angle is about 7 ~ 12 degrees. Normal walking speed is about 4 ~ 5km per hour.

When the gait is determined based on the characteristics of FIG. 3 and FIG. 5, the rotation of the pelvis, the muscular asymmetry between the hip flexor and the hip extensor, and the support of the monotonic limb supporter The difference between the ratio and pressure, the resulting temporal information, and the muscle strength of the lower limbs can be identified, and the flowability of walking can also be identified.

In addition, changes in the gait interval of the hip joint, adductor and abductor imbalance, Q-angle change, tibia rotation, foot arch collapse, and gaps in the inner and outer valgus I can figure it out.

In addition, the forward angle can predict whether the toe is turning outwardly or inwardly, and the dynamic factors for this walking.

On the other hand, it is possible to look at the change in plantar pressure as well as the mass movement of the human body as information to distinguish the detailed gait step, Figure 6 is a movement and foot planter during the standing period of the foot to explain the integrated analysis process of the embodiment of the present invention An illustration showing the pressure change.

As shown, the steps from the initial contact state to the step just before the toe release are sequentially shown, and the movements on the rear surface (FIG. 6A) and the side surface (FIG. 6B) and the plantar pressure change according to each movement (FIG. 6C) are shown. This foot movement can be identified through the state of the dynamic pattern of plantar pressure.

This plantar pressure change pattern (ie, the central movement pattern) is a process of moving from the heel past the center of the sole to the big toe, moving from the heel along the lateral side to the outside to the big toe. .

The plantar pressure change pattern indicates whether or not flatfoot (Forefoot varus, Forefoot valgus, Rearfoot varus). When this flat foot occurs, hip rotation and femur internal rotation occur due to anterior rotation of the pelvic ilium, and at the same time the instep height due to arch collapse There is a correlation between lowering and increased foot flexion (Dorsi Flexion), which increases the time the foot presses on the ground during walking. Therefore, it is possible to grasp such a relative movement according to the occurrence of flat foot or, on the contrary, to determine whether the flat foot and the time the foot presses the ground during walking through the rotation of the hip and femur.

However, in the apparatus 100 for diagnosing physical malformation syndrome according to an exemplary embodiment of the present invention, since the plantar pressure sensor is superior in resolution or reliability to the 3D sensor, it may be determined by weighting the measurement information of the plantar pressure sensor.

Since the pattern of gait is due to the inherent angle and neurological movement of the human body, most of the subjects do not deviate greatly from the pattern. Therefore, the body malformation syndrome can be diagnosed by precisely analyzing the movement of the human body based on the walking pattern.

Each of the functional units of FIG. 2 performing the physical misalignment diagnosis using the characteristics of the gait will be described in more detail.

First, the pressure measuring unit 131 converts the measured value of the plantar pressure sensor 110 into plantar pressure on the human body. That is, through the plantar pressure pattern of the gait as described above with reference to FIG. 6, the part measured by the plantar pressure sensor 110 corresponds to the part of the foot to determine the pressure corresponding to the plantar pressure of the human body and converts the information. .

The 3D information generator 132 first performs an initialization step of quantifying the movement of the human body by mapping a space for diagnosing the movement of the human body and a virtual space measured by the 3D sensor, and then measures the measured value of the 3D sensor 120 in the human body movement. It is converted to 3D information about the body misalignment diagnosis apparatus 100 according to an embodiment of the present invention is a fixed device for measuring the walking of the human body information about the space to be measured and the measured information (image Information, depth information, etc.) and apply the actual unit information to obtain quantitative numerical information on the movement or rotation according to the measured motion information. To this end, the calibration process of mapping the measurement space to the virtual 3D space using the information on the bottom surface and the size information on the measurement object is performed as an initialization process to increase the reliability of the quantification of the measurement. In addition, since the measurement of the human body within a specific range in a fixed area can be increased by adjusting the measurement range.

In particular, the 3D information generation unit 132 limits the measurement value of the 3D sensor 120 measuring the movement of the human body through the depth information of the image or the point cloud format to the human body, and converts it into a skeleton type having a joint. It may be mistaken as a movement out of the walking step by the measurement error or noise, the measurement angle of the human body.

Accordingly, the 3D information generator 132 compensates the human body movement by receiving information from the 3D information compensator 134 as information for compensating for the 3D information or information on the point of time or movement pattern specifying the human body movement among the plantar pressure change patterns. can do. For example, according to the plantar pressure pattern shown in FIG. 6, it is possible to determine whether the foot is currently in contact with the ground, dropped, only the heel, the entire foot, and the time to press the ground for each section of the foot. The patterned movement information of the upper extremity muscles and skeletal system is used to filter the information that is excessively out of the expected movement pattern of the skeletal system according to the change of plantar pressure pattern or to adjust the measurement parameters to follow the movement pattern (especially Skeleton movement) is generated as compensated 3D information.

This 3D information includes a detailed spatial model of the human body that can obtain information about the rotation and torsion of each joint and the skeleton by responding to the set skeleton and the structure of the body as well as the posture change of the human body, the vertical movement of the body, and the measured body. Each partial coordinate information may be included.

The measurement information storage unit 136 stores the converted values of the pressure measuring unit 131 and the 3D information generating unit 132 at a synchronized time, and is simply measured as the plantar pressure of the human body in the pressure measuring unit 131. And store the measured information (measured raw sensor values, pressure area and intensity and temporal information on the pressure in each compartment, including comparison of the support of the lower limbs, and information about the area of the sole) with the measurement time information. 3D information generation unit 132 converted into 3D information of the human body (measured raw sensor values, values of each part obtained by mapping to the human body, coordinates of each joint and skeleton obtained by mapping to the skeleton, corrected joints and skeletons) Coordinates, etc.) may be stored together with the measurement time information, and the actual measurement time points of the two measurement units may be accurately synchronized with the same time information. Alternatively, the conversion values of the pressure measuring unit 131 and the 3D information generating unit 132 may be stored in the measurement information storage unit 136 at regular intervals according to specific time information.

The information stored in synchronization with the time information stored in the measurement information storage unit 136 may be repeatedly drawn out and utilized as needed. The information can be easily identified by identifying the exact walking step-by-step time point or linked to the measurement information of one side. have.

Meanwhile, the plantar pressure sensor 110 and the 3D sensor 120 respectively identify patterns of plantar pressure change or human body movement patterns, and if there is an abnormality, perform additional analysis on a highly correlated linkage. The dynamic pressure change analyzer 137 and the dynamic 3D information analyzer 138 may analyze each dynamic change according to a required time point or period.

The dynamic pressure change analysis unit 137 dynamically analyzes plantar pressure stored in the measurement information storage unit 136 over time, and according to the change in pressure, the walking step of FIG. 2 or the center of gravity movement of FIG. It is possible to analyze the position of each foot according to the foot pressure change of 6 and the walking of FIG.

The dynamic 3D information analyzing unit 138 dynamically analyzes 3D information about the human body motion stored in the measurement information storage unit over time, and the human body movement includes the walking step of FIG. 2 or the center of gravity movement of FIG. 3. It is possible to analyze the position of each foot according to the walking of 5, foot shape or movement according to the walking of FIG. 6, and also to measure and analyze skeletal movement and joint movement and rotation of the human body.

Now, examples of a method of measuring the body misalignment having correlation through the plantar pressure and the 3D information of the human body will be described with reference to FIGS. 7 to 10.

First, the most directly correlated part of the foot according to the state of the foot is the movement of the pelvis. According to the walking, the pelvis shows three characteristic movements, and as shown in FIG. 7, a total of 8 degrees of horizontal rotational motion (A) is issued by 4 degrees in each direction according to the walking. The translational motion B occurs, and the translational motion C within 5 degrees each up and down occurs on the y axis.

Since the movement of the pelvis is directly related to the abnormality of the foot, abnormalities occur in the movement of the pelvis when abnormalities occur in the foot, and conversely, abnormalities occur in the foot when the abnormal pelvis occurs, resulting in physical disorder syndrome.

For example, the dynamic pressure change analyzer 137 measures the time the foot presses the ground, and predicts problems of flat feet, knees, hips, and pelvis when one foot presses the ground longer than the opposite foot. In particular, the increase in the time the foot pushes to the ground just before the toe-off may result in excessive arch collapse or Dorsi flexion above normal angle, excessive hip and femur, internal rotation of the knee joint, and anterior rotation of the pelvic cotton bone. Accompany In addition, the rotation of the opposite pelvis occurs at the end of the standing phase, depending on how far the big toe is pushed just before the toe-off. When the driving force of the big toe of one foot is insufficient, the rotational force of the ipsilateral and opposite pelvis falls, which can be confirmed by linking the operating pressure change analyzer 137 and the dynamic 3D information analyzer 138.

In addition to the basic diagnosis, it is necessary to examine the correlation between the movement of the human body and the musculoskeletal system for a more accurate diagnosis.

In general, the pelvis rotates in the sagittal plane, and the rotation of each Ilium occurs in the anterior rotation and posterior rotation in the flexion plane. In the cross section, the entire rotation of the pelvis occurs (forward rotation of the lower limb moving forward), and the rotation of the entire pelvis from the front surface, that is, upward movement on the side where weight load is applied, and downward movement on the other side. As the position of the pelvis changes on these planes during walking, the sacrum also rotates right and left alternately around the vertical and oblique axes according to each walking cycle. Therefore, the movement of the pelvis has a specific movement pattern according to the step of walking, and it is possible to suspect that body misalignment occurs when such a pattern is shifted.

The hip joint connected to the pelvis also appears as a movement pattern as the gait, femur (Femur) is rotated at the same time as the pelvis. In the right heel contact (Initial Contact), the right hip joint is slightly externally rotated depending on the relative posterior position of the left anterior superior iliac spine (ASIS). During most of the right lower stance phase, as the left anterior superior iliac pole moves forward, the movement of the internal rotation occurs in the right hip joint, with the maximum internal rotation occurring at 50% of the walking cycle. From 50% of the walking cycle to the middle mid swing, the right lower limb is lifted and moves forward, resulting in external rotation in the right hip. There is a small amount of internal rotation of the right hip joint from the middle stunt to the contact of the right heel.

The hip and femur movements associated with the gait are associated with the knee joint. At the heel contact point, the knee joint is in a relative external rotational position of 2-3 degrees. Since the internal rotation of the tibia is greater than the femur throughout the standing phase, the knee joint gradually turns inward. By the end of the toe release, the knee joint is about 5 degrees of relative internal rotation. During the swing phase, the knee joint rotates outward to prepare for the next heel contact.

Looking at the movement of the weight and lower limbs in the foot, as shown in Figure 6 the weight of the heel at the point of heel contact is moved forward along the outer surface. The period is from the initial contact of the heel to the mid stance, the period of movement from the back to the front of the body, which is the anterior, posterior (flexion, extension) exercise (ankle, knee, hip) 10).

The weight then moves from the outside of the sole to the inside, from the mid stance to the end of the stance, from the pelvis to the opposite pelvis, to the pelvic rotation, to the pelvic rotation. This is the time of rotation of the torso contrary to the rotation, which is the movement of ankle (Pronation), knee abduction (Adduction + Internal rotation), hip rotation and extension (Internal rotation + Extention), anterior rotation (anterior rotation) As a result, the femur causes simultaneous internal rotation, extension, and adduction.

Lastly, the section of weight movement from the inside of the sole to the big toe is the stage of obtaining a propulsive phase, which is the forward and backward movement of the hip, knee, and ankle joints, and the internal rotation of the hip and femur. Accompanied by internal rotation.

The correlation between the dynamic plantar pressure changes and the ankle, knee, femur, hip, and pelvis according to the gait can be found to be highly correlated. Can be. In particular, when a problem occurs at a specific site, when the problem of a specific site is identified through medical data on the relationship generated by linking a particular problem, it is necessary to confirm the problem at the other site having correlation through dynamic information analysis.

In the exemplary embodiment of the present invention, the foot problem may be first identified based on information obtained through the plantar pressure sensor, which is relatively more reliable than the 3D sensor, and then the associated upper limb movement may be analyzed.

The foot arch has a force against gravity and cushions it. In addition, it generates a driving force when walking and running, the balance of the left and right arch forms an upright joint alignment and a correct posture. Medial longitudinal arch is an important structure that is the center of the foot arch, and from front to back, the first metatarsals, medial cuneiform, navicular, talus, calcaneus, etc. Consists of dog bones. In the lateral longitudinal arch of the foot, three bones, such as a 5th metatarsal, a cubic and a calcanus, constitute an arch. The transverse arch of the foot is composed of five metatarsal bones, and the metatarsal bones do not come into contact with each other to form joints, but rather a kind of virtual interstitial muscle between the metatarsal bones. It can be called an arch.

The higher inner arch of the foot is called Pes Cavus, and the lower inner arch is called Pes planus (Flat foot). This deformation of the arch of the foot affects the pelvis and knee joints and shifts the center and line of gravity of the body, leading to body disorder syndrome.

For example, flatfoot is one of these foot problems.

FIG. 8 is a conceptual view illustrating the types and features of flat feet that can be distinguished in an embodiment of the present invention, and shows three types of typical flat feet as shown.

Forefoot varus is a condition in which the big toe is higher than the fifth toe. The forefoot varus, which is observed in the open kinetic chain & uncompensated, is primarily driven by the lateral side of the foot in the closed kinetic chain & compensated, which reduces the forward thrust when walking.

In addition, in order to compensate for this, the subtalar joint is excessively pronation, and the metatarsal joint is flattened by taking a foot-flat position. As shown, if you do not support the weight (up) and if you support the weight can be seen inward (down).

In other words, when supporting the weight through the dynamic pressure analysis unit 137 (bottom), it can be seen that the foot is flat foot through the increased pressure pattern of the front and the inside of the foot as a whole. (propulsive phase), that is, the low pressure of the front and the inner part of the foot can be seen in the full pass.

In addition, in order to check the type, the front, back, inside, and outside of the ankle joint in the case of not supporting the weight and the foot state when supporting the weight and the weight through the dynamic 3D information analysis unit 138 The angle can be checked and the forefoot varus can be identified by the left and right body weight imbalance and the difference in the height of the ankle support, the increase of the internal rotation of the femur, the increase of the Q-angle, and the twist of the tibia.

Forefoot valgus refers to the fifth toe rising above the big toe, the opposite of the forefoot valgus. For this reason, the forefoot valgus can be seen as if it does not support the weight as shown (upper) and if it supports the weight and collapses outward in the opposite direction (lower).

In this case, when the weight is supported through the dynamic pressure analyzer 137, the overall pressure of the front and the outside of the foot can be confirmed, and thus, when the big toe is walking, the driving force (propulsive phase) is pushed to the ground. You can see the increased pressure on the front and the outer part of the foot in the engraver.

In addition, the dynamic 3D information analysis unit 138 can be confirmed through the front, rear and internal and lateral angles of the ankle joint when the weight is not supported and the foot state when supporting the weight and when supporting the weight. In addition, the forefoot valgus can be identified by the decrease in weight shift to the opposite side due to the imbalance between the left and right weight shifts, the difference in the height of the foot support, and the reduced propulsion.

Rearfoot varus is the inversion of the calcaneus at the back of the foot toward the midline. In response to this deformation, the subtalar joint is compensated through the subtalar joint pronation during weight support, causing the inner surface of the forefoot to make much contact with the ground during the standing phase. As shown in the figure does not support the weight (up), when supporting the weight is shown to collapse inward (bottom).

In this case, when supporting the weight through the dynamic pressure analysis unit 137, the overall pressure after the foot can be confirmed, and thus the pressure on the inner side of the heel (Heel contact) can be confirmed. In addition, the increase in the standing time can be confirmed by the collapse of the medial calf.

In addition, the dynamic 3D information analysis unit 138 can be confirmed through the front, rear and internal and lateral angles of the ankle joint when the weight is not supported and the foot state when supporting the weight and when supporting the weight. After the imbalance of the left and right body weight shift and the height difference of the ankle support, the lower medial calf due to the pronation of the subtalar joint, the vertical angle of the tibia and the abduction angle of the foot Identify the foot varus.

In this case, when the flat foot is detected through the dynamic pressure change analyzer 137, detailed diagnosis of the type and the cause is required, and the time-synchronized dynamic 3D information analyzer 138 may be used to identify the flatfoot.

On the other hand, when detecting the toe-out through the dynamic pressure change analysis unit 137, the cause may be a problem of the foot, such as flat foot or a forearm, twist of the tibia, rotation of the knee joint, hip joint Shortening of the rotator cuff, excessive foreground of the femur, abnormal Q-angle, etc. may be the cause.

Through the dynamic pressure change analyzer 137, it is possible to check whether the flat foot is described above, and whether or not the supinated foot is present. A characteristic feature of the foot is the abnormally high medial longitudinal arch. Since the instep of the foot of the foot (Inversion) from the forefoot to compensate for it (Eversion) and the toe becomes a claw toe (Claw toe).

On the other hand, other tibial torsion, rotational change of the knee joint, shortening of the external rotator muscle of the hip, excessive foreground of the femur, abnormal Q-angle can be confirmed through the 3D analysis unit 138. For example, it is not simply a diagnosis of a limb or a flat foot, but rather a limb by the forefoot valgus and a more accurate diagnosis of a change in knee joint rotation was found due to correlation misalignment.

Tibia torsion is when the transmalleolar axis connecting medial malleolus and lateral malleolus is rotated by more than 20 degrees. It can be judged to be the cause of the steps.

The rotational change of the knee joint is called the tibiofemoral rotation (TFR). In the movement of the lower leg, femur and tibia form the knee joint, and at the same time, the femur (Femur) is transferred to the tibia (Tibia) or the problem of the tibia to the femur (Femur).

The closed-kinetic or open kinetic chain determines the movement of the tibia-on-femoral and femoral-on-tibial to the femur, and in what way. The type of movement depends on whether you are moving at. Tibial femoral movements include flexion in the sagittal plane, extension movements, and rotation in the horizontal plane.

 Tensor fascia lata is a two-joint muscle that passes through the hip and knee joints.If the femoral root muscle is overused due to weakening of the gluteus medullus, the femur is rotated internally and the tibia rotates externally. Done. The femoral tibial rotation is different from the tibial torsion, the tibial torsion is the osteogenic change of the tibia itself, and the TFR torsion occurs in the knee joint. This movement causes rotational deformation of the pelvis, hip joints and knee joints, causing complex problems.

Therefore, if there is a limb walking, it is not tibial torsion, and if there is a change in rotation of the knee joint, it may be a problem due to weakening of the gluteus maximus and exercise prescription for strengthening the gluteus maximus may be prescribed.

Shortening of the external rotator is a case in which the external rotator muscles, including the ideal, upper, lower bilateral, internal obstructive, external obstructive, and femoral muscles, are tense or shortened. Will appear.

Femoral retrotorsion of the femur means that the hip is deteriorated. The torsion angle of the femur is tilted 15 degrees forward, but if the hip is deceased, the point on the femur is behind the point in the tibia. The normal hip movement does not occur and the femur rotates outward to compensate for the femoral remorse, resulting in a step of the arm.

The Q-angle is a relative indicator of the patellar pullover of the quadriceps (Quadriceps femoris) against the patella, and as the centerline of the patella in the ASIS of the pelvis, as shown in FIG. 9. After drawing a straight line and a straight line from the centerline of the patella to the tibial tubercle, the angle between them was measured. The normal angle is 10-15 degrees, and the angle increases with hip adduction, hip internal rotation, and foot over pronation.

In this way, when abnormalities are not known whose specific cause is unknown only by plantar pressure, it is possible to confirm whether or not the abnormalities are related to the abnormalities through 3D information, and the information about the correlated sites is obtained through the 3D information thus obtained. If you check, you can see information about other parts that are relevant. In addition, when additional confirmation is required for various related problems determined through 3D information, 3D information may be supplemented through plantar pressure change patterns to identify the state and cause of physical malformation syndrome.

Accordingly, the dynamic 3D information analysis unit 138 moves up and down, left and right movements of the body mass, movements of the torso and arms, and shoulder and arm movements, pelvic movements, hip movements, knee joint movements, and ankle joints. In order to measure the motion, it is possible to determine and correct or determine an abnormality based on the joint motion characteristic pattern in the subdivided walking step as shown in FIG. 10.

The misalignment syndrome diagnosis unit 135 illustrated in FIG. 2 analyzes a walking step that subdivides a walking step according to an analysis result of at least one of the dynamic pressure change analyzer 137 and the dynamic 3D information analyzer 138 described above. After requesting and receiving each of the dynamic pressure change analysis unit 137 and the dynamic 3D information analysis unit 138 or a combination of analysis results based on interoperability based on the detailed walking step information of the unit 133, Identify the association of each site to generate diagnostic information about body malalignment syndrome.

For this purpose, medically studied skeletal, joint and muscle correlation information can be used, and exercise prescription can be presented based on the diagnostic information.

Correlation information on flatfoot will be described as an example of such medically studied skeletal, joint and muscle correlation information.

Flat foot is an important pathological factor due to excessive subtalar joint pronation of the ITband syndrome. Excessive internal rotation of the tibia pulls the distal iliotibial band over the lateral femoral epicondyle, creating an Iliotibial band friction, Increase the Q-angle at the joint.

The tibia of the pronation foot shows inward rotation, the femur shows outward rotation, and the pelvis increases in the anterior tilt and Q-angle. The tibia of the supped foot shows external rotation, the femur shows internal rotation, and the pelvis decreases the posterior tilt and Q-angle. Therefore, by synthesizing these features in or out of the foot or by measuring the inside and out of the foot can be confirmed whether the other features are generated subsequently.

An important diagnostic target for flatfoot detection is the effect of femur on the pelvis with internal rotation. When the femur rotates inward, the femur head moves backwards, which causes the entire pelvis to tilt forward. This in turn causes rotational deformation of the body.

Eventually, due to foot problems, the tibia rotates internally, the tibiofemoral joint flexes, the femur rotates internally, and the hip joint flexes. This causes the pelvis to tilt forward and the lumbar spine is excessive. As the pelvis descends forward, only the spine side is created by the pelvis, and the upper side forms only the side in the other direction. In addition, the pain and stress caused by the distorted pattern of the load affects the autonomic nervous system, which may cause dysfunction of the genitourinary system and gastrointestinal tract, and misalignment may also cause musculoskeletal dysfunction.

This can cause flat feet, such as forefoot varnish, forefoot, and forefoot varus (Forefoot varus, Forefoot valgus, Rearfoot Varus), which can cause all problems above the feet.

Accordingly, when the malformation syndrome diagnosis unit 135 detects an abnormality of the foot using the correlation information, the problem of the upper part is checked through 3D information of the human body in each step of the diagnosis and diagnoses the problem.

FIG. 11 is a flowchart illustrating a process of diagnosing physical malformation syndrome in the apparatus for diagnosing physical malformation syndrome according to an embodiment of the present invention. As shown in FIG. 11, FIG. 11 is a space for first diagnosing a human body movement and a virtual space measured by a 3D sensor. The measurement is prepared through an initialization step that maps and quantifies human movement.

When the measurement is started, the body misalignment syndrome diagnosis apparatus calculates and synchronizes the 3D information on the movement of the human body through the 3D sensor and the plantar pressure of the human body following at least two steps of human body walking through the plantar pressure sensor (in the embodiment, the scaffold). It is stored in the internal measurement information storage unit according to the time information.

The body misalignment syndrome diagnosis apparatus subdivides the gait step through at least one of analysis of plantar pressure changes stored in the internal measurement information storage unit or analysis of changes in 3D information.

If necessary, the body misalignment syndrome diagnosis device may compensate 3D information according to the human body movement corresponding to the plantar pressure change pattern for each step of walking, and store the compensation information in accordance with the occurrence time of the compensated movement in the internal measurement information storage unit. Can be.

The body misalignment syndrome diagnosis apparatus checks the association between the body misalignment parts and each part while checking the foot pressure and the 3D information change according to the walking time stored in the internal measurement information storage unit at the same time or in combination based on the linkage. Analyze In this case, as described above, it is preferable to determine the cause of misalignment in detail in consideration of the correlation of abnormal occurrences.

 When such an analysis is completed, the body misalignment syndrome diagnosis apparatus may provide a diagnosis of the type and cause of misalignment based on the correlation between the analyzed body misalignment parts and each part.
