[0002]

2. Description of the Related Art In rehabilitation such as after surgery for fracture or amputation of a lower limb, after surgery on a joint, or after a stroke of paralysis, for example, the body of a patient who is initially in a standing position Training is performed to reduce fluctuations in the position of the center of gravity, and after this training, training is performed to stand up from a chair or floor in a well-balanced manner. In performing such training, in particular, when performing training to reduce fluctuations in the position of the center of gravity when the user takes a standing posture, a body sway meter 1 as shown in FIG. 5 is conventionally used.

The center of gravity sway meter 1 has a rectangular detection plate 2 on which a patient places both feet, and load detection sensors 3 ‥ provided at the front, left rear, and right rear of the detection plate 2.
And a calculation unit 4 that determines the center of load from the loads detected by the load detection sensors 3 # and uses this as the center of the center of gravity of the patient, and a display device that continuously displays the center of gravity determined by the calculation unit 4. 5 is provided. And with such a configuration, the body sway meter 1
When the patient takes a standing posture with both feet on the detection plate 2, each load detection sensor 3 各 detects the load applied to each position, and the calculation unit 4 calculates the load center of the patient from the detected values. The center of gravity is obtained, and the obtained center of gravity can be displayed on the display device 5 as a trajectory K indicating the movement of the center of gravity as shown in FIG. 6, for example.

According to such training, the state of the sway of the center of gravity of the patient can be known by looking at the trajectory K displayed on the display device 5, so that the size of the trajectory K, that is, the trajectory shown in FIG. By looking at the size of the figure formed by the outline L1 of K, it is possible to determine whether the balance state of the patient's body is good or not, so that the doctor or the patient can grasp the recovery state by training. .

There are inconveniences such as a difference between the intention and the actual movement of the center of gravity, and the inability to grasp the speed of the movement of the center of gravity. Due to such inconvenience, when performing training of the center of gravity shift, the trainer accompanies the patient as usual, and the patient shifts the center of gravity according to the instructions of the trainer, and the trainer or doctor sees this and the function of the center of gravity shift function of the patient is performed. It is common to know the recovery status.

[0006] However, such training accompanying the trainer is burdensome for both the patient and the trainer, and the training for the patient to move the center of gravity right, left, front and rear in accordance with the instructions of the trainer is monotonous and interesting. Therefore, it is difficult to work on the training itself seriously, and the recovery of the function of shifting the center of gravity, ie, the balance function, becomes difficult.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a center-of-gravity shift training apparatus capable of independently performing a center-of-gravity shift recovery training without a trainer, and having a fun. Is to do.

Next, a center-of-gravity shift training method using the center-of-gravity shift training apparatus 10 having such a configuration will be described. First, a training target according to the obstacle of the subject is set, and a corresponding one of the prepared menus is selected from the input means 20. Then, the setting function 15a operates in response to a signal from the input means 20, and the movement pattern of the target image M is determined.

Next, the subject is placed on the detection plate 11, and in that state, the measurement system switch of the center-of-gravity shift training apparatus 10 is turned on. Then, the loads applied to both feet of the subject are detected by the three load cells 12..., And the respective detection signals are sent to the calculation means 13 via the amplifier 16, the filter 17, and the AD converter 18. The calculating means 13 inputs each detection signal sent thereto, performs arithmetic processing as data per unit time, and outputs a signal from the output function 13d to the center-of-gravity position image displaying means 19.

In addition, in the display device 14, a moving pattern is determined first by the setting function 15a of the target image display means 15 separately from the image C of the center of gravity, and the target images M that move based on this moving pattern are displayed. ing.

Then, the subject views the image C at the position of the center of gravity of the subject and the moving target image M on the display device 14, and adjusts the movement of the target image M so that the image C is superimposed on the target image M. To move the center of gravity. When the image C overlaps with the target image M in this manner, the detecting means 21 determines the judgment by the judging function 21a, and erases the superimposed target image M from the display device 14 by the erasing function 21b. A false sound is emitted by c to notify the subject to that effect. Further, the subject follows the remaining target images M in the same manner, and sequentially deletes the target images M from the display device 14.

When the preset training time is over or when all the target images M are deleted, the target image display means 15 and the center of gravity position image display means 1

Note that the result display means 23 displays, together with the stored target images M, a line that divides the circumference of a predetermined center point into eight equal parts and a circle indicating the distance from the center point.

When the result is displayed in this manner, for example, as shown in FIG. 3, if there are many target images M at the lower left, the center of gravity can be moved to the lower left smoothly. Thus, the recovery state of the subject can be easily grasped. In addition, similarly to the conventional center of gravity sway meter 1 shown in FIG.
Even at 0, the trajectory indicating the fluctuation of the position of the center of gravity as shown in FIG. 5 can be recognized by printing out the display device 14.

In such a center-of-gravity shifting training apparatus 10, the target image M is moved on the display device 14 by the movement function 15c of the target image display means 15, and the moving target image M is followed by its own. By superimposing the image C of the position of the center of gravity, the subject can be trained in the movement of the center of gravity without directly listening to the instructions of the trainer or the doctor. An input means 20 for inputting a movement pattern of the target image M... And a setting function 15a for setting the movement pattern of the target image M.. The doctor and the trainer previously set the movement pattern of the target image M... With the setting function 15a in accordance with the training target of the subject, so that the doctor and the trainer can respond to the failure location of the subject and its recovery state. Training can be done.

It is possible to enjoy training such as superimposing the image C on the target image M in a game-like manner, and the storage unit 22 and the result display unit 23 display an overlapping position when the center-of-gravity position image C overlaps the target image M. Since the training result can be displayed above, the result of the training can be visually recognized from the display device 14 as a result of the game, and the recovery state of the subject can be easily known from the result.

FIG. 4 is a view showing another embodiment of the training apparatus for moving the center of gravity of the present invention. In this figure, reference numeral 30 denotes a training apparatus for moving the center of gravity. The center-of-gravity shift training apparatus 30 is different from the center-of-gravity shift training apparatus 10 shown in FIG. 1 in that an automatic activation mechanism 31 is connected to a load cell (load detecting means) 12 # and that the load cell cells 12 Calculation means 3
Second, the calculation means 33 and the movable range setting means 34 are sequentially connected.

When the load cells 12... Detect a load equal to or more than a predetermined value, the automatic activation mechanism 31 receives the detection signal and calculates the calculation means 13, the target image display means 15, the center of gravity position image display means 19, the storage means 22, Result display means 23
, Etc., and the display means 14 are activated, and when the load cell 12... Detects a load smaller than a predetermined value, the detection signal is received and the respective means and the display device are activated. Is to stop. Here, the predetermined value is a load that is clearly considered to have the subject on the detection plate 11, for example, a load of several kg to about 10 kg.

The second calculating means 32 detects that the subject
After the first ride, the position of the center of gravity of the subject is calculated based on the detection signal from the load cells 12. Is stored, and the maximum distance of the center of gravity of the subject in the front-rear direction and the maximum distance of the center of gravity in the horizontal direction are calculated from the stored center of gravity. The movable range setting unit 34 causes the maximum center-of-gravity movement distance in the front-rear direction calculated by the calculation unit 33 to correspond to the vertical distance on the display screen of the display device 14, and displays the maximum center-of-gravity movement distance in the left-right direction on the display device 14. This corresponds to the distance in the horizontal direction of the screen, whereby the movable range of the center of gravity of the subject is enlarged or reduced to the entire display screen of the display device 14, and, for example, the center of the movable range of the center of gravity of the subject is true. Even if the position is shifted from the position of the center of gravity, the training using the entire display screen of the display device 14 can be performed without being affected by this.

In order to carry out the method of training the center of gravity using the training apparatus 30 for moving the center of gravity, first, the training target corresponding to the obstacle of the subject is set by the subject himself / herself, similarly to the training apparatus 10 for moving the center of gravity. Alternatively, a trainer, a doctor or the like sets and selects. Next, the subject rides on the detection plate 11. Then, the load cells 12 of the detection plate 11 detect the load of the subject, and in response to this detection value, the automatic activation mechanism 31
3. Activate each unit incorporated in the computer system, such as the target image display unit 15, the center-of-gravity position image display unit 19, the storage unit 22, the result display unit 23, and the display unit 14.

Prior to the training, the subject moves his / her body forward, backward, left and right for a preset time, for example, 30 seconds or 1 minute, and sets the movable range of the center of gravity. When the subject moves his / her upper body for the set time, the second calculating means 32 calculates the center-of-gravity position for each predetermined unit time based on the detection values from the load cells 12. The means 33 calculates the maximum center-of-gravity movement distance in the front-rear direction and the maximum center-of-gravity movement distance in the left-right direction of the subject from the storage (data) of the center of gravity position calculated by the second calculation means 32. Then, the movable range setting means 34 makes the maximum center-of-gravity movement distance in the front-rear direction calculated by the calculation means 33 correspond to the vertical distance of the display screen of the display device, and displays the maximum center-of-gravity movement distance in the left-right direction on the display device. Is made to correspond to the horizontal distance of the display screen, thereby making the movable range of the center of gravity of the subject correspond to the size of the display screen of the display device 14.

After the center of gravity movable range of the subject is made to correspond to the multiple descriptions on the display screen in this manner, an image C of the center of gravity position is displayed on the display device 14 in the same manner as in the training by the center of gravity movement training device 10. Display and target image M ...
Is displayed, and the center of gravity is moved on the display device 14 so that the image C is superimposed on the target image M. Further, when the training for a predetermined time is completed, or when the training itself is to be stopped in the middle of the training, the subject simply descends from the detection plate 11 to obtain the calculating means 13, the target image displaying means 15, Center of gravity position image display means 1
9, the means incorporated in the computer system such as the storage means 22, the result display means 23, and the display means 14 can be stopped. That is, when the subject descends the detection plate 11, the load cells 12... Each detect a load equal to or more than the predetermined value, but only detect a load less than the predetermined value (a state in which the load is not accurately detected). As a result, the automatic activation mechanism 31 operates to stop the activation of the respective units and the display device 14.

In such a center-of-gravity shift training apparatus 30, the provision of the automatic activation mechanism 31 allows the subject to simply ride on the detection plate 11 to operate the calculation means 13, the target image display means 15, and the display device. 14 is started, whereby the center-of-gravity movement training apparatus 30 itself can be started to be in a state where training can be performed. When it is desired to end the training, the start-up of the center-of-gravity movement training apparatus 30 is performed simply by descending from the detection plate 11. Can be stopped, and the subject can perform training independently and easily without a trainer, a doctor, or the like.

Further, prior to the training, the subject is required to
By moving the body back and forth and right and left on the vehicle, and moving the center of gravity, the second calculating means 32, the calculating means 33, and the movable range setting means 34 determine the movable range of the position of the center of gravity of the subject, and Since the range corresponds to the screen of the display device,
The subject can perform training using the entire display screen without changing the size of the movable range of the center of gravity of the subject.

The training apparatus for moving the center of gravity of the present invention is not limited to the above embodiment. For example, when the training time is set, the elapsed time or the remaining time may be displayed on the display device 14. Well, display device 14
The number of target images remaining above or the number of captured target images may be displayed. Further, only one target image M may be displayed on the display device, and when this is captured and deleted, another target image M may be newly displayed. In addition, as shown in FIG. 2, an obstacle image S... Is displayed on the display device separately from the target image M.
Further, the image C at the position of the center of gravity must not be allowed to pass over the obstacle image S, so that the movement of the image C at the position of the center of gravity when following the target image M must bypass the obstacle image S. This may enable more advanced training.

As described above, the center-of-gravity shifting training apparatus according to the first aspect of the present invention moves the target image on the display device by the target image display means, and follows the moving target image to position its own center of gravity. It is possible to train the center of gravity movement by superimposing the images of the subjects, so that the subject can easily perform the recovery training by himself without placing a heavy burden on the trainer or doctor.

In the training apparatus for moving the center of gravity according to a third aspect, the overlapping position when the center-of-gravity position image overlaps the target image can be displayed on the display device by the storage means and the result display means. Therefore, the result of the training can be visually recognized from the display device as the result of the game, and the recovery state of the subject can be easily grasped from the result.

According to a fourth aspect of the present invention, when the load detecting means detects a load equal to or more than a predetermined value, the load detecting means receives the detection signal and activates the calculating means, the target image display means and the display device to detect the load. When the means detects a load less than a predetermined value, the subject is simply connected to the load detecting means by receiving the detection signal and connecting the calculating means, the target image displaying means and the automatic starting mechanism for stopping the starting of the display device to the load detecting means. The load is detected by riding on the detection plate, and the calculation means, the target image display means, and the display device are activated, whereby the center-of-gravity shift training device itself can be activated to perform training. When it is desired to end the training, the trainer can stop the activation of the center-of-gravity movement training apparatus simply by descending from the detection plate. Only in the subject alone and not have a doctor or the like can also be carried out easily trained.

In the center-of-gravity shifting training apparatus according to the fifth aspect, the center of gravity of the subject is calculated by the second calculating means, and the center of gravity of the subject is calculated from the storage of the center of gravity calculated by the second calculating means by the calculating means. The maximum center-of-gravity movement distance in the front-rear direction and the maximum center-of-gravity movement distance in the left-right direction of the user are further calculated, and the maximum center-of-gravity movement distance in the front-rear direction calculated by the calculation means by the movable range setting means is calculated in the vertical direction of the display screen of the display device. Since the maximum distance to the center of gravity in the horizontal direction corresponds to the distance in the horizontal direction of the display screen of the display device, the subject rides on the detection plate prior to training and By moving the center of gravity, the movable range of the position of the center of gravity can be determined, and this movable range can be made to correspond to the screen of the display device. Therefore, the subject can display the size of the movable range of the center of gravity of the subject as it is. It is possible to perform training using the entire screen.
