The balance and weight shift training apparatus of the present invention, as shown in Figures 2 to 4, the sensor receiving module 110, the sensor receiving module 110 for detecting the weight and balance of the diagnosis target on the footrest 111 The microcomputer control module 120 receives the detected signal and the wired / wireless communication module 130 receives the data transmitted from the microcomputer control module 120 and transmits the data to the computer 140.

The scaffold 111 has a size to which a diagnosis subject can put a foot, and the scaffold 111 includes a pressure sensor 112, a distance measuring sensor 113, and a three-axis tilt sensor 114. 110 is installed.

A plurality of pressure sensors 112 are installed on the upper surface of the scaffold 111. Two such pressure sensors 112 are provided at positions corresponding to the heel and heel of the foot, respectively, and a plurality of these pressure sensors 112 may be installed on the footrest 111 as necessary.

The pressure sensor 112 is pressed by the foot of the diagnosis subject to detect the weight of the diagnosis subject according to the displacement value, and the pressure applied to the respective pressure sensor 112 by the foot different pressure sensors The pressure value applied to 112 will be different.

That is, the pressure sensor 112 is installed on the front and rear and left and right sides of the two scaffold 111, respectively, as shown in Figure 2, the pressure sensor of the front (close to the micom control module 120 of Figure 2) ( 112 is pressed by the force applied by the front heel, and is pressed in accordance with the force applied to the pressure sensor 112 located on the left and right of these front pressure sensor 112.

In addition, the pressure sensor 112 at the rear is pressed according to the force applied by the heel, and the pressure is applied to the pressure sensor 112 positioned at the left and right of the pressure sensors 112 at the rear.

The front two pressure sensors 112 are pressed by the front heel, but the loads on the inside and the outside of the foot is different, so they are pressed by different loads, and the two pressure sensors 112 on the back are heeled It is pressed, but the load on the inside and outside of the foot is different, so they will be pressed under different loads.

Therefore, each pressure sensor 112 has a different pressure value depending on the load applied by the foot.

The side of the footrest 111 is provided with a distance measuring sensor 113 for measuring the distance between the footrest 111 and the footrest 111, the distance measuring sensor 1113 is on the opposite surface of each footrest 111 Many are installed.

In addition, the sensor receiving module 110 is provided with a three-axis inclination sensor 114 as shown in Figure 3, both sides of the three-axis inclination sensor 114, the band 115 to be worn on the waist of the diagnosis target, etc. Is fixed, and wearing means such as Velcro is provided for convenience of wearing.

The three-axis inclination sensor 114 measures the upper body inclination value due to the inclination of the upper body of the diagnosis subject using a gyroscope, the pressure sensor 112, the distance measuring sensor 113 and the three-axis inclination sensor 114. Data measured at) is sent to the microcomputer control module 120.

The microcomputer control module 120 sends the data input from the sensor receiving module 110 to the wired / wireless communication module 130, and the wired / wireless communication module 130 sends the input data to the computer 140.

The microcomputer control module 120 includes an A / D converter (not shown) for converting an analog signal input from the pressure sensor 112, the distance measuring sensor 113, and the 3-axis tilt sensor 114 into a digital signal. There may be built-in, the data converted in the microcomputer control module 120 is sent to the computer 140 by the wired or wireless communication module 130.

That is, the wired / wireless communication module 130 may transmit data input from the microcomputer control module 120 through a wire connected to the computer 140 or use wireless communication such as Bluetooth or Zigbee.

In addition, the computer 140 has a built-in program for analyzing the data input through the sensor receiving module 110 through the wired / wireless communication module 130, of course.

In addition, although the microcomputer control module 120 and the wired / wireless communication module 130 are separately shown in the drawing of FIG. 2, the microcomputer control module 120 and the wired / wireless communication module 130 may be embedded in the bottom or the inside of the scaffold 111.

In the balance and weight shift training apparatus of the present invention having such a configuration, the diagnosis subject is placed on the footrest 111, and the pressure sensor 112 installed on the footrest 111 is pressed by the sole.

Accordingly, the pressure sensor 112 measures the weight of the diagnosis subject, and sends data to the microcomputer control module 120 according to the load applied to each pressure sensor 112.

The microcomputer control module 120 receives data input from each pressure sensor 112 and measures the distance of the footrest 111 by the distance measuring sensor 113.

That is, when the distance between the footrest 111 is far apart, a strong load acts on the pressure sensor 112 located inside the left foot and the right foot (the pressure sensor adjacent to the distance measuring sensor 113 in FIG. 2).

Meanwhile, in the present invention, the "balance training" is to adjust the load so that the same load is applied to the four pressure sensors 112, and the "worm movement training" is to selectively move the load of the left and right feet, Different loads are applied to the sensor 112.

That is, the balance training is to put the left foot and the right foot on the footrest 111 respectively, so that the load of the left foot and the right foot is equally applied to the pressure sensor 112 without any motion or movement in the standing position, and the weight movement training is the pressure When the load applied to the sensor 112 is different in either the left or right foot, the weight is applied to the foot to which the load is weakly applied for a certain time.

In addition, when the footrest 111 is in close proximity to the normal interval (shoulder width), the load applied by the left foot and the right foot should be uniform, and when the footrest 111 is in the narrow interval (the gap between the shoulder width) and the left foot and The load applied by the right foot causes a stronger load to the outside of the foot.

The pressure sensor 112 data pressed by the foot is sent to the microcomputer control module 120, and the microcomputer control module 120 transmits the data according to each pressure sensor 112 through the wired / wireless communication module 130. Sent to computer 140.

The computer 140 analyzes data by a built-in program to show pressure values acting on each pressure sensor 112, and the four pressures installed on the two footrests 111 on the screen of the computer 140. The pressure value applied to the sensor 112 is displayed.

While the data is displayed on the screen, the diagnosis subject performs the balance training. If the load applied to the pressure sensor 112 is different between the left foot and the right foot, the diagnosis subject intentionally gives strength to the foot to which the weak load is applied. do.

As described above, the diagnosis subject exerts a force on the weak foot, by applying a strong force to the weak part of the heel or heel of the foot to match the pressure value displayed on each pressure sensor 112.

That is, when the load of the left foot is weak, the diagnosis subject gradually applies a force to the left foot to increase the pressure value of the pressure sensor 112 of the left foot, and a stronger load is applied to the pressure sensor 112 corresponding to the left foot. The pressure value of 112 is raised.

In addition, the pressure value is the pressure value of the pressure sensor 112 corresponding to the front heel or heel of the left foot is displayed on the computer 140 screen, the person suffering from the fact while looking at the computer 140 screen of the pressure sensor 112 of the heel or heel The pressure is applied to the lower heel or heel.

Thus, by adjusting the load according to each of the pressure sensor 112 in the diagnosis object standing on the footrest 111, the load acting on the left foot and the right foot, respectively.

This balance training is to train to adjust the load applied to the foot equally without moving the leg or upper body in a state in which the diagnosis target is standing on the footrest 111.

In addition, if you want to exercise weight movement training, the diagnosis target is looking at the computer 140 screen is displayed on the pressure value for the load applied to the pressure sensor 112 in a state of rising on the footrest 111.

On the screen of the computer 140, the pressure value of the pressure sensor 112 is displayed on the screen of the computer 140 according to the load applied by the left or right foot, and the subject of diagnosis is displayed on the foot of the lesser of the left or right foot. Force is applied to load a lot.

At this time, the diagnosis subject puts the weight on one leg of the left foot or the right foot, and hardly puts the weight on the other foot. On the other hand, the diagnosis target, for example, maintains the standing position centering on the left foot, and the weight is not carried on the right foot.

That is, the diagnosis subject is standing on the left foot and the right foot, but the right foot is standing as if holding the right foot so that almost no weight is carried.

In this way, the subject to be diagnosed puts weight on the left foot, so that the pressure value of the footrest 111 corresponding to the left foot of the subject is excessively displayed on the screen of the computer 140, and the pressure of the footrest 111 corresponding to the right foot is displayed. The value shows a very low display.

Thus, the weight of the left foot or the right foot is kept in a state where it stands for a predetermined time, and the time of the body movement training is performed for a set time.

The body movement training is of course adjusted according to the physical condition, rehabilitation state of the subject.

In addition, the body movement training can be carried out by the two footrest 111 about the width of the shoulder, the narrower the distance between the footrest 111 or carried out by freely selecting the footrest 111 in a diagonal position Can be.

Meanwhile, the 3-axis tilt sensor 114 is worn on the waist of the subject to be diagnosed and sends data on the center or tilt of the upper body to the sensor receiving module 110 during the balance training or body movement training, and the upper body tilts along with the balance training. Balance training and body movement training will be continued with the upper body inclined so that the upper body is not tilted or tilted.

The balance training and weight transfer training is carried out not only for the rehabilitation subjects, but also for those who experience discomfort due to walking, and it is possible to balance the walking by the balance training and weight transfer training.

The LM actuator 150 is for moving the footrest 111 fixed to the upper side, the LM actuator 150 is provided with a motor control unit (not shown in the figure) for rotating the ball screw.

Since the LM actuator 150 uses a conventional one, a detailed description thereof will be omitted.

The balance and weight shift training apparatus according to the second embodiment of the present invention as described above will be omitted, the description overlapping with the first embodiment, while moving the footrest 111 by the LM actuator 150 ( The load acting on the 111 can be sensed, and thus the pressure value according to the movement of the footrest 111 can be measured without performing a walking operation.

That is, the diagnosis subject moves the motor control unit of the LM actuator 150 in a state in which the foot is placed on the footrest 111 to move the position of the footrest 111 forward or backward, and thus moves to the footrest 111. The pressure value of the pressure sensor 112 according to the load of the foot is measured.
