Description

  The present invention relates to a motion training device used by a trainee to acquire a correct motion, and a motion training system using the motion training device.

  In recent years, the aging of the population has progressed, and there are an increasing number of cases in which the musculoskeletal disorder is caused by abnormalities in joints and bones, muscle strength, and the like. If the musculoskeletal disorder occurs, there is a problem that support and care are required, which hinders independent living. It has been proposed to collectively refer to this type of musculoskeletal disorder as “locomotive syndrome”. Musculoskeletal disorders occur not only in the elderly, but also in patients who have undergone surgery, for example.

  In order to prevent such musculoskeletal disorder and recover the function, exercise function training for the elderly and function recovery training after surgery have been conventionally performed. Trainees often receive guidance from a leader such as a physical therapist so that they can acquire the correct behavior when performing this type of training.

  However, since the number of instructors is limited, the trainee is not always able to receive guidance during training, and the trainee does not always take the posture and motion different from the posture and motion instructed by the trainee. You may not be able to learn the correct posture and movement. In particular, if there is pain when performing postures and movements necessary for training, the trainee tries to avoid painful postures and movements even if he / she knows it is necessary when he / she is not receiving guidance from the leader. There is a possibility that the posture and movement necessary for training will not be performed. Conversely, some trainees may perform excessive training when not receiving guidance from the instructor. Excessive training is not desirable because it can make symptoms worse.

  In addition, it is desirable to perform exercises for preventing musculoskeletal disorders and for functional recovery for mild musculoskeletal disorders not only at training facilities (rehabilitation facilities) but also at home. However, as described above, when the instructor cannot receive guidance, the trainee may perform self-training, and may not perform training at home or the like.

  Among locomotive syndromes, devices for training muscles mainly related to the ankle (anterior tibial muscle, soleus muscle, gastrocnemius muscle, etc.) have been proposed to prevent musculoskeletal disorders related to walking (for example, patents). Reference 1). Patent Document 1 describes a configuration in which a tread plate is arranged on a pedestal so that a seesaw motion is possible. The maximum inclination angle of the tread with respect to the upper surface of the pedestal is regulated by the front end and rear end of the tread striking against the upper surface of the pedestal. Further, the cited document 1 describes that the maximum inclination angle of the tread is adjusted according to the user by changing the size of each part of the component. In the configuration described in Patent Document 1, it is possible to exercise to contract muscles related to the ankle by placing the foot on the tread and tilting the tread.

  Various other devices for exercising exercise devices related to walking have been proposed. For example, Patent Document 2 discloses one or two footrest plates on which a person sits and steps on a foot. The structure which measures the load change which a footrest board receives by a load measurement part is described. The apparatus described in Patent Document 2 is used for the exercise of stepping on a footrest plate, and employs a configuration that measures factors such as the number of steps, strength, length, and speed. In the technique described in Patent Document 2, target values can be set for these elements.

JP 2011-156111 A Japanese Patent Laid-Open No. 11-253575

  As described above, the technique described in Patent Document 1 is a device that stretches muscles related to the ankle, and there is a description that the maximum inclination angle of the tread is adjusted according to the user. Changing the corners requires replacing the components. Therefore, in order to adjust the maximum inclination angle to suit the user, it is necessary to prepare multiple types of components with different specifications, and a configuration for replacing the components is also necessary. Therefore, there is a problem that the cost is increased if the adjustment according to the user is made possible. In addition, since it can be used only for stretching the muscles related to the ankle, the content of the exercise is uniform, and even if it is limited to walking, it does not sufficiently improve the locomotive syndrome. Furthermore, regarding the impairment of the walking function of the elderly, it is necessary to pay attention not only to the ankle joint, but also to the knee joint and the hip joint, and the device described in Patent Document 1 is not effective in preventing or restoring the walking function. It is enough.

  On the other hand, since the technique described in Patent Document 2 is assumed to be stepping as an exercise, when compared with the device described in Patent Document 1, certain effects can be obtained with respect to prevention of obstacles and recovery of function of walking function. Conceivable. In addition, because it is possible to set targets for the elements related to stepping and the elements related to stepping are set to the electronic control means, multiple types of components with different specifications can be prepared or the components can be replaced. It is considered that the increase in cost is suppressed.

  However, the target set in the configuration described in Patent Document 2 is the number of steps, strength, length, speed, etc., and is basically a goal related to the intensity of exercise. It is not suitable for the purpose of learning. In other words, after receiving guidance from the instructor, even if you try to self-train at a place or time where you can not receive instruction from the instructor, such as at home, you will not get clear goals about posture and movement, so in the end, The problem arises that training is inadequate or excessive.

  The present invention is an operation for enhancing the training effect by notifying the trainee of the difference between the posture and motion when the trainee is instructed and the posture and motion when the trainee is performing self-training. It is an object of the present invention to provide a training device and to provide a motion training system using the motion training device.

  In order to achieve the above object, the motion training device according to the present invention includes a footrest part on which a trainee puts his / her foot, a load detection part that detects a load acting on the footrest part at a plurality of locations of the footrest part, and A load information extraction unit that extracts current load information corresponding to at least one of the posture and motion of the trainee from the load detected by the load detection unit, and the current load information extracted by the load information extraction unit An information evaluation unit for calculating an evaluation amount for evaluating a difference from the target load information, a presentation unit for presenting the trainee with the evaluation amount calculated by the information evaluation unit, and target load information used by the information evaluation unit are set. And a target setting unit.

  In this motion training apparatus, it is preferable that a pair of left and right foot placement portions are provided so that the left and right feet of the trainee are placed one by one, and a plurality of load detection portions are provided for each left and right foot placement portion.

  In this motion training apparatus, it is preferable to further include an interface unit for transmitting / receiving the target load information.

  In this motion training apparatus, it is preferable to further include an interface unit that extracts the current load information extracted by the load information extraction unit.

  In this motion training apparatus, it is preferable that the target load information set in the target setting unit is generated based on the current load information extracted by the load information extraction unit.

  In this motion training apparatus, it is preferable that the presentation unit delivers the evaluation amount to the operation display device and causes the trainee to present the evaluation amount through the operation display device.

  In this motion training apparatus, it is preferable that the presentation unit transmits the evaluation amount to the portable terminal by wireless communication, and causes the trainee to present the evaluation amount through the portable terminal.

  In this motion training apparatus, it is preferable that the foot placement unit includes a medium attachment member for detachably attaching a foot position recording medium for recording the position of the foot of the trainee.

  The motion training system according to the present invention includes a plurality of motion training devices used by a trainee, and the motion training device rests a footrest portion on which the trainee places a foot and a load acting on the footrest portion. A load detection unit that detects at a plurality of locations of the unit, a load information extraction unit that extracts current load information corresponding to at least one of the posture and motion of the trainee from the load detected by the load detection unit, and a load information extraction unit An information evaluation unit that calculates an evaluation amount for evaluating a difference between the current load information extracted by the target load information set in advance, a presentation unit that presents the evaluation amount calculated by the information evaluation unit to the trainee, and information A target setting unit that sets target load information used by the evaluation unit, a first interface unit that receives and transmits the target load information, and a second interface unit that extracts current load information extracted by the load information extraction unit, Training equipment When the trainee uses the reference device when the trainee uses it as a reference device for training while receiving guidance, and when the trainee uses the rest of the motion training device as a training device for self-training The target load information generated by the target setting unit based on the current load information extracted by the load information extraction unit is delivered to the training device through the first interface unit, and when the trainee uses the training device, the load information extraction unit Is transferred to the reference device through the second interface unit.

  According to the configuration of the present invention, training is performed by notifying the trainee of the difference between the posture and motion when the trainee is instructed and the posture and motion when the trainee is performing self-training. The effect that the effect is enhanced can be expected. That is, after performing training under the guidance of a leader such as a physical therapist, when performing self-training without receiving guidance from the leader, check whether the movement and posture are the same as when receiving the guidance. Since self-training is performed, it is possible to acquire correct postures and movements that are free from self-discipline.

  The motion training apparatus described below measures the magnitude of the load for each foot of the trainee and the load bias for each foot. Further, the motion training device is configured to measure changes in the magnitude and bias of the load over time as necessary. This motion training device is assumed to be used in a standing position. However, it can also be used in a sitting position unless it sits deeply. In other words, if the seated trainee raises both feet from the floor, the position of the buttocks moves by gravity and the trainee's load is dispersed and supported by the buttocks and feet. For example, the motion training apparatus described below can be used.

  Furthermore, it is assumed that training is performed without assistance by handrails, etc., but for trainees who have insufficient muscle strength for walking and are at risk of falling, It is permissible to add a handrail or an auxiliary tool that suspends the body of the trainee. Further, instead of providing a handrail or the like, the body may be supported by putting a hand on furniture such as a desk or chair or a wall.

  This motion training device is basically used by trainees under the guidance of instructors such as physiotherapists or when they are used for self-training without guidance from the instructor. . In this embodiment, it is assumed that the motion training device used under the guidance of the instructor is different from the motion training device used in self-training, and the basic specifications and functions of both are the same. The details may be different. Hereinafter, as necessary, the motion training device used under the guidance of the instructor is referred to as a “reference device”, and the motion training device used in self-training is referred to as a “training device”.

  When using a motion training device for self-training rather than under the guidance of a leader, it is recommended to use it after receiving guidance from the leader first. That is, when using the training device, it is recommended to use the reference device first.

  The exercises performed using this motion training apparatus are assumed to be an exercise called locomotion training such as standing on one leg with eyes open, squats, and moving the arms and upper body. However, the type of exercise is not particularly limited as long as it can be exercised using the motion training apparatus. The type of exercise to be performed is indicated by a screen display of a display device (described later).

  As shown in FIG. 1, the motion training apparatus includes a measuring unit 1 that measures the load of the trainee, a processing unit 2 that analyzes and evaluates a measurement value acquired from the measuring unit 1, and an analysis performed by the processing unit 2. A presentation unit 3 that presents the result of evaluation and an input unit 4 that acquires an instruction operation for the processing unit 2 are provided. The presentation unit 3 and the input unit 4 are basically connected to a controller 5 provided separately from the measurement unit 1.

  The controller 5 includes a dot matrix type display device 51 formed of a flat panel display such as a liquid crystal display, and an operation device 52 such as a switch having a mechanical contact or a touch switch. That is, an operation display device in which functions of operation and display are integrated is used as the controller 5. At least one of the display device 51 and the operation device 52 may be integrated with the measurement unit 1.

  The processing unit 2 includes a processor that operates according to a program, and is selected from a microcomputer, a DSP (Digital Signal Processor), an FPGA (Field-Programmable Gate Array), a PIC (Peripheral Interface Controller), and the like. That is, the processing unit 2 implements each function described below by executing an appropriate program by the processor.

  As shown in FIG. 2, the measurement unit 1 includes a base plate 11 placed on the floor, a left foot placement unit 121 and a right foot placement unit 122 provided on the base plate 11, and a downward direction received by the left foot placement unit 121. A load sensor 131 as a load detection unit that measures a load and a load sensor 132 as a load detection unit that measures a downward load received by the right footrest unit 122 are provided. The left foot placement unit 121 is provided for placing the left foot of the trainee, and the right foot placement unit 122 is provided for placing the right foot of the trainee. Regions corresponding to the left footrest portion 121 and the right footrest portion 122 are each formed in a rectangular shape with rounded corners in plan view.

  The base plate 11 is formed so as to have a strength that does not substantially bend even when the load of the trainee is applied. However, when it is assumed that the motion training apparatus is used on a floor that does not flex, such as a concrete floor, the base plate 11 has a configuration in which a plurality of plate materials are connected in a foldable manner, a synthetic resin thin plate, A configuration that can be deformed by a sheet can be employed. When such a configuration is adopted, the area can be made smaller when not in use than when it is used, so that storage and carrying are facilitated. The base plate 11 is provided with a non-slip (not shown) formed of rubber or the like on the lower surface so that it does not slip when placed on the floor.

  The left footrest portion 121 and the right footrest portion 122 include pressure receiving plates 123 and 124 that receive a downward load of the trainee, respectively, and the upper surfaces of the pressure receiving plates 123 and 124 are substantially flush with the upper surface of the base plate 11. Placed in. For example, a configuration in which the recesses 111 and 112 are formed on the upper surface of the base plate 11 and the pressure receiving plates 123 and 124 are accommodated in the recesses 111 and 112 is employed. The pressure receiving plates 123 and 124 are supported on the base plate 11 by a support material (not shown) such as a coil spring.

  Although the upper surface of the base plate 11 and the upper surfaces of the pressure receiving plates 123 and 124 are arranged to be substantially flush with each other, there is a possibility that a step is generated between the upper surface of the base plate 11 and the upper surfaces of the pressure receiving plates 123 and 124. Therefore, it is preferable to cover the entire upper surface of the base plate 11 including the left foot placement portion 121 and the right foot placement portion 122 with the decorative sheet 14. The decorative sheet 14 is formed of a flexible synthetic resin sheet, and transmits a load acting on a region corresponding to the left footrest portion 121 and the right footrest portion 122 to the pressure receiving plates 123 and 124.

  Load sensors 131 are disposed between the four corners of the pressure receiving plate 123 and the base plate 11, and load sensors 132 are disposed between the four corners of the pressure receiving plate 124 and the base plate 11, respectively. In short, the downward load acting on the left footrest 121 and the right footrest 122 is measured by the four load sensors 131 and 132. As the load sensors 131 and 132, strain gauges or load cells are used.

  Here, it is not essential to provide four load sensors 131 and 132 for the left footrest portion 121 and the right footrest portion 122, respectively, and three or more load sensors are provided for the left footrest portion 121 and the right footrest portion 122, respectively. 131 and 132 need only be provided, and three or more load sensors 131 and 132 need not be aligned. That is, the load sensors 131 and 132 are arranged so as to measure downward loads acting on the left footrest portion 121 and the right footrest portion 122 at three or more different points.

  In the configuration described above, a configuration in which the pressure receiving plates 123 and 124 are accommodated in the recesses 111 and 112 provided in the base plate 11 is adopted, but the left foot placement portion 121 and the right foot placement portion 122 are formed in a shape in which the lower surface is opened. You may form and arrange | position so that the upper surface of the baseplate 11 may be covered. In this configuration, the upper surfaces of the left footrest portion 121 and the right footrest portion 122 become pressure receiving plates 123 and 124, and the pressure receiving plate is formed in a space formed between the left footrest portion 121 and the right footrest portion 122 and the upper surface of the base plate. A support material such as a coil spring that supports 123 and 124 and load sensors 131 and 132 are disposed. This structure is almost the same as the structure of a scale that measures weight using a load sensor.

  As described above, since the load sensors 131 and 132 are provided for the pressure receiving plates 123 and 124, the downward load acting on the pressure receiving plates 123 and 124 is measured. Further, by providing several load sensors 131 and 132 for each of the pressure receiving plates 123 and 124, it is possible to detect the position such as the center of gravity of the downward load acting on each of the pressure receiving plates 123 and 124.

  If a two-dimensional orthogonal coordinate system is defined in which the front of the base plate 11 is positive in the x-axis direction and the left direction of the base plate 11 is positive in the y-axis direction, the pressure acting on the pressure receiving plates 123 and 124 will be described. The position of the center of gravity of the load to be obtained is obtained as follows. The loads detected by the four load sensors 131 corresponding to the left pressure receiving plate 123 are w1, w2, w3, w4, and the coordinates of the load sensor 131 are (x1, y1), (x2, y2), (x3, y3). ), (X4, y4). In this case, the coordinates (xg, yg) of the center of gravity are as follows. xg = (w1 * x1 + w2 * x2 + w3 * x3 + w4 * x4) / (w1 + w2 + w3 + w4), yg = (w1 * y1 + w2 + y2 + w3 * y3 + w4 * y4) / (w1 + w2 + w3 + w4). Similarly, the coordinates of the center of gravity are obtained for the right pressure plate 124.

  In addition, it is also possible to provide a large number (for example, 20 or more) of load sensors 131 and 132 for each of the pressure receiving plates 123 and 124 to detect the load at each location of the pressure receiving plates 123 and 124. As this type of configuration, it is possible to employ a pressure-sensitive touch switch in which a large number of piezoelectric elements are arranged on the pressure receiving plates 123 and 124. When a large number of load sensors 131 and 132 are used, it is possible to measure the distribution of downward loads acting on the pressure receiving plates 123 and 124.

  When several load sensors 131 and 132 are provided, it is preferable that the pressure receiving plates 123 and 124 are formed to have such a strength that they are not substantially bent by a downward load from the trainee. On the other hand, when a large number of load sensors 131 and 132 are used, the pressure receiving plates 123 and 124 are preferably flexible.

  The measurement unit 1 outputs a measurement value of the downward load for each of the load sensors 131 and 132 to the processing unit 2. As described above, the processing unit 2 includes the arithmetic unit 20 including a processor that operates according to a program, and the arithmetic unit 20 implements each function described below by executing an appropriate program. Further, the processing unit 2 includes an acquisition unit 21 that acquires measurement values from the load sensors 131 and 132, a storage unit 22 that stores temporal changes in the measurement values acquired by the acquisition unit 21, and other computer systems 6 and the like. And an interface unit 23 that communicates with an external device.

  The acquisition unit 21 has an AD conversion function of converting a measurement value, which is an analog value for each of the load sensors 131 and 132, into a digital value, and outputs a digital value at regular time intervals. The acquisition unit 21 may include the same number of AD converters as the load sensors 131 and 132. However, a configuration is provided in which a multiplexer is provided to sequentially (cyclically) convert the measured values of the load sensors 131 and 132 into digital values. Is preferably adopted. With this configuration, the measurement values of the load sensors 131 and 132 become serial data, so that data transmission is easy. The period at which the output values of the individual load sensors 131 and 132 are sampled in the acquisition unit 21 may be about 0.01 to 0.5 s as long as a human response can be detected. This numerical value is an example, and is not intended to limit the sampling period.

  The processing unit 2 has a function as a load information extraction unit 201 that extracts current load information corresponding to at least one of the posture and motion of the trainee from the measurement values of the load sensors 131 and 132 acquired by the acquisition unit 21. . The load information extraction unit 201 extracts current load information regarding the gravity center position of each of the pressure receiving plates 123 and 124 obtained from the loads detected by the load sensors 131 and 132. That is, the load information extraction unit 201 uses the position of the left and right center of gravity for each sampling as current load information regarding the posture of the trainee, and uses the time change of the position of the left and right center of gravity for each sampling as the current load regarding the motion of the trainee. Used for information. The current load information may be adopted only for one of the posture and motion of the trainee.

  It is expected that the temporal change in the position of the center of gravity includes many fluctuation components other than the action focused on the trainee. Therefore, the current load information related to the movement of the trainee uses information selected from the moving average of the center of gravity position, the locus of the center of gravity position, the positional relationship between specific points of the center of gravity position, and the like. When the locus of the center of gravity position is used, a change attribute focusing on the direction and distance in which the center of gravity position changes is used for the current load information.

  The storage unit 22 includes a history storage unit 221 that records changes in the current load information extracted by the load information extraction unit 201 during a period in which the trainee is using the apparatus, and a target that stores preset target load information. A storage unit 222. The target load information will be described later. The processing unit 2 includes an interface unit 23 that exchanges target load information set in the target storage unit 222, and includes an interface unit 24 that extracts current load information stored in the history storage unit 221 as necessary.

  The target load information is information that is the target of the current load information obtained when the trainee is using the device. Therefore, the trainee can learn a required posture and action by performing physical operations related to the posture and action so that the current load information approaches the target load information. Such target load information is extracted from the current load information when the trainee performs physical manipulation under the guidance of the instructor. Further, since the target load information is associated with the posture and the motion, the target storage unit 222 can store a plurality of types of target load information according to the posture and the motion.

  Since the target load information regarding the posture is static information, when the trainee is in an appropriate posture, the instructor registers it in the target storage unit 222 by operating the operation device 51 of the controller 5. Is possible. For example, the current load information in a state where the knee joint is located immediately above the arch or the ankle joint is adopted as the target load information. This is because, when knee pain occurs in the trainee, the knee joint may not be located directly above the arch or ankle joint when landing because the knee is open outward.

  Since the target load information related to the movement is dynamic information with time change, the current load information stored in the history storage unit 221 is extracted from the interface unit 24 to the outside after the training of the trainee is completed. The computer system 7 is used. In the computer system 7, a program for supporting the setting of the target load information is executed, and the instructor generates appropriate target load information from the history of the current load information by operating the computer system 7 according to the instructions of the support program. It becomes possible to do.

  The computer system 7 may be a server connected to a public network such as the Internet. In this case, a configuration in which target load information is interactively generated with the server using the controller 5 may be adopted. Is possible.

  Further, since the target load information can be exchanged through the interface unit 23, the separately created target load information can be received through the interface unit 23 and set in the target storage unit 222. The interface unit 23 includes a connector for connecting a storage medium 6 such as a memory card or a USB memory, and can exchange target load information via the storage medium 6. However, when the interface unit 23 is configured for communication that communicates through a public network such as the Internet, the target load information can be exchanged by data communication without using the storage medium 6.

  So far, the configuration for generating the target load information from the result of the trainee exercising under the guidance of the instructor, mainly in the rehabilitation facility, etc., of the configuration of the motion training apparatus has been described. In the following, a configuration necessary for the trainee to perform exercise at home or the like without receiving guidance from the leader will be described. When the trainee exercises without receiving the guidance of the instructor, if the person can confirm that the movement or posture is the same as that performed under the guidance of the instructor, the movement or posture is prevented from becoming self-flowing. It is considered possible.

  Therefore, the processing unit 2 includes an information evaluation unit 202 that compares the current load information extracted by the load information extraction unit 201 with the target load information while the trainee is using the apparatus. The target load information that the information evaluation unit 202 compares with the current load information is selected from the target load information stored in the target storage unit 222 and set in advance in the target setting unit 203 provided in the processing unit 2. The information evaluation unit 202 evaluates the difference between the current load information and the target load information set in the target setting unit 203, and displays the evaluation result as an evaluation amount on the display device 51 through the presentation unit 3. That is, the evaluation amount is presented to the trainee through the presentation unit 3.

  Since the target load information is obtained from the current load information under the guidance of the instructor, the posture of the trainee is obtained by obtaining an evaluation amount regarding the difference between the target load information and the current load information in the information evaluation unit 202. You can see the degree of difference from when you were instructed about movement.

  The evaluation amount obtained by the information evaluation unit 202 is displayed on the display device 51 provided in the controller 5. The controller 5 may be provided with a sounding device that outputs sound, and may be able to present an evaluation amount by sound. That is, the presentation unit 3 causes at least visual presentation of visual evaluation and auditory presentation through the controller 5 for the evaluation amount.

  The operation device 52 provided in the controller 5 is selected from a touch switch overlaid on the screen of the display device 51, a push button switch having a mechanical contact, or the like. When the controller 5 is provided, the presentation unit 3 and the input unit 4 are provided in the controller 5. The acquisition unit 21 of the processing unit 2 is preferably provided integrally with the measurement unit 1, and the other configuration of the processing unit 2 is preferably provided in the controller 5.

  A display example of the evaluation amount on the screen of the display device 51 is shown in FIG. In the display example shown in FIG. 3, a balance display unit 511 indicating the ratio of loads acting on the left foot placement unit 121 and the right foot placement unit 122 is provided at the center of the screen, and the evaluation amount output from the information evaluation unit 202 is It is displayed on the left and right of the balance display unit 511. In the illustrated example, since “45% left and 55% right” is displayed on the balance display portion 511, it is indicated that the center of gravity is biased to the right side.

  The illustrated example shows an evaluation amount related to the posture. Marks (circles) 514 and 515 indicating the position of the center of gravity as target load information and the position of the center of gravity as current load information extracted by the load information extraction unit 201 are shown. Marks (cross marks) 512 and 513 are shown. Therefore, the trainee changes the posture so that the positions of the marks 512 and 513 are close to the positions of the marks 514 and 515, so that the trainee has a substantially matching posture at the time of guidance by the instructor. Here, the evaluation amount regarding the difference is indicated by the distance and direction between the marks 512 and 513 and the marks 514 and 515.

  In the case of indicating the evaluation amount related to the operation, the trajectory for moving the center of gravity and the desired position may be indicated as the target load information, and at the same time, the position of the center of gravity corresponding to the current load information may be displayed. By such a display, the trainee recognizes the deviation of the current position from the desired position. Therefore, the trainee can perform a physical operation so as to match the current load information with the target load information, and acquire a correct action.

  By the way, in the structure mentioned above, there exists a possibility that the present load information may be fluctuate | varied with the position which puts a leg on the footrest parts 121 and 122. FIG. Therefore, in order to train to be in the same posture and motion as when receiving guidance using the motion training device, it is necessary to match the position where the foot is placed every time the motion training device is used. For this purpose, a foot position recording medium 17 formed of a sheet-like material such as paper or cloth is used for the base plate 11. The foot position recording medium 17 is made of a material that can be filled in with a writing tool such as a felt pen, is not easily torn even when a foot is placed, is flexible, and is relatively inexpensive. Therefore, a non-woven fabric having water resistance is used for the foot position recording medium 17, for example. Further, as shown in FIG. 4, a foot-shaped reference line 171 is printed on the surface of the foot position recording medium 17 in a light color (gray, pastel color, etc.).

  The base plate 11 is formed with two alignment projections 113 that abut the angular position of the foot position recording medium 17. The alignment protrusion 113 is formed in an L shape in plan view. Further, a magnet 15 is embedded in the vicinity of the alignment convex portion 113 in the base plate 11. Accordingly, the foot position recording medium 17 can be fixed in position with respect to the base plate 11 by sandwiching a part of the foot position recording medium 17 between the presser plate 16 and the magnet 15 formed of a magnetic material. It has become.

  In this configuration, the foot position recording medium 17 is positioned against the alignment protrusion 113, and the position of the foot position recording medium 17 is fixed using the magnet 15 and the pressing plate 16 that are medium attachment members. Accordingly, the foot position recording medium 17 can always be fixed at the same position with respect to the base plate 11. Further, the foot position recording medium 17 can be detached from the base plate 11 by removing the pressing plate 16. Therefore, the foot position recording medium 17 can be attached to and detached from the left foot placement unit 121 and the right foot placement unit 122.

  As the medium mounting member, instead of the magnet 15 and the pressing plate 16, a clip-shaped pinching member (not shown) for pinching a part of the foot position recording medium 17 may be provided on the base plate 11. That is, the position of the foot position recording medium 17 is fixed with respect to the base plate 11 by the end portion of the foot position recording medium 17 being sandwiched between the sandwiching members. When the alignment convex 113 is provided, the foot position recording medium 17 may be attached to the base plate 11 using a double-sided adhesive tape as a medium attachment member.

  The foot position recording medium 17 is used as follows. In other words, when the trainee receives instruction from a rehabilitation facility and uses the motion training apparatus, the trainee uses the reference line 171 printed on the foot position recording medium 17 attached to the base plate 11. Put your feet on as a guide. In this state, the instructor writes a positioning line 172 on the toe side and the heel side of the trainee so as to trace the circumference of the foot using a felt pen or the like. The timing for writing the positioning line 172 to the foot position recording medium 17 by tracing the foot of the trainee may be either before or after the training. After the training, the foot position recording medium 17 is removed from the base plate 11 and handed over to the trainee.

  The foot position recording medium 17 on which the positioning line 172 tracing the foot of the trainee is written is attached to the motion training device used by the trainee at home or the like. When the foot position recording medium 17 is used in a rehabilitation facility by bringing the foot position recording medium 17 into contact with the alignment convex portion 113 to accurately position the foot position recording medium 17 and placing the foot on the positioning line 172 written on the foot position recording medium 17. You can put your feet in the same position. That is, when the motion training apparatus is used at home or the like, it can be used under the same conditions as the training performed under the guidance of the leader at the rehabilitation facility.

  The foot position recording medium 17 may be made of a material that deforms into a shape along the foot by heating, such as a sheet of heat-shrinkable resin, instead of paper or cloth. When the foot position recording medium 17 using this kind of material is used, for example, the foot position recording medium 17 may be heated with a dryer or the like with the foot placed on the foot position recording medium 17.

  Further, in the motion training apparatus arranged in the rehabilitation facility, the foot position recording medium 17 is exchanged for each trainee, so that a new foot position record is recorded for each trainee while the motion training apparatus is used by many people. A foot is placed on the medium 17. Therefore, even when the trainee uses the motion training device barefoot, the motion training device is used cleanly.

  In the configuration example described above, it is assumed that the measurement unit 1 and the controller 5 are provided separately, and the measurement unit 1 and the controller 5 are connected by wire, but there is no wireless connection between the measurement unit 1 and the controller 5. The communication path may be formed to transmit data. In the configuration described above, the display device 51 is provided in the controller 5, but the display device 51 may be provided integrally with the measurement unit 1 as shown in FIG. 5. In this configuration, the display device 51 is disposed in front of the left foot placement portion 121 and the right foot placement portion 122 on the base plate 11. Furthermore, instead of the dedicated controller 5, a smartphone, a tablet terminal, a PDA (Personal Digital Assistant), or the like can be used instead of the controller 5. In this case, dedicated application software for causing a smartphone, a tablet terminal, a PDA, or the like to function as the controller 5 is used. Hereinafter, smartphones, tablet terminals, PDAs, and the like are collectively referred to as portable terminals. When a portable terminal is used as the controller 5, it is possible to store target load information in the trainee's portable terminal and use the portable terminal as the controller 5 of another motion training apparatus.

  With the above-described configuration, the motion training apparatus of the present embodiment can be used as follows. That is, as shown in FIG. 6, the trainee uses the motion training device (reference device) 10A, which is a facility of a rehabilitation facility provided in a hospital or the like, under the guidance of the instructor. The target load information 61 is created using the current load information obtained by the apparatus 10A. The trainee sets the target load information 61 passed from the instructor in the target setting unit 203 of the operation training apparatus (training apparatus) 10B provided at home, so that the same posture and movement as when the instruction was received. Will be trained to aim. Since the history of the current load information obtained by this training is recorded in the history storage unit 221, it can be taken out as history information 62 through the interface unit 23. Therefore, by giving the history information 62 to the instructor, the instructor can know the status of training of the trainee at home, and can be used for reference for the next instruction. In this way, by giving the target load information 61 from the instructor to the trainee and passing the history information 62 from the trainee to the instructor, the instructor can perform appropriate instruction to the trainee. .

  As can be seen from the use example described above, the motion training device 10A arranged in the rehabilitation facility and the motion training device 10B used by the trainee at home do not necessarily have the same performance. For example, in the motion training device 10B, the interface unit 24 that is necessary for generating the target load information may be omitted. Further, in the motion training apparatus 10A, touch switch type load sensors 131 and 132 in which a large number of piezoelectric elements are arranged are arranged on the pressure receiving plates 123 and 124. In the motion training apparatus 10B, the load sensors 131 and 132 such as the load cell described above are arranged. 132 may be used. In this configuration, in the motion training device 10 </ b> A, instead of placing the foot position recording medium 17 on the measuring unit 1, the foot positions acquired by the load sensors 131 and 132 are printed by a printer or the like to be trained as the foot position recording medium 17. Give it to the person.

  Further, in the above-described configuration example, the left foot placement portion 121 and the right foot placement portion 122 are divided, but it is possible to adopt a configuration in which one foot placement portion is provided so as to place both feet. Compared to a configuration in which one footrest portion is provided with two footrest portions, the accuracy of posture and motion detection is lowered, but if it is a simple use, it becomes practical and a reduction in manufacturing cost can be expected. On the other hand, by adding an acceleration sensor or a gyro sensor in addition to the load sensors 131 and 132, it becomes possible to detect the posture and motion of the trainee more accurately.

  The presentation unit 3 not only displays an evaluation amount indicating the degree of difference between the current load information and the target load information on the display device 51, but also reduces the evaluation amount so that the visually impaired person can use the evaluation amount. The volume may be presented. For example, the sound may increase when the difference from the target load information increases, and the sound may decrease when the difference decreases. Or you may make it become a high tone when a difference with target load information becomes large, and become a low tone when a difference becomes small. In these operations, when no sound can be heard, the current load information substantially matches the target load information.

  Furthermore, when the trainee uses the motion training device 10B at home, the use may be excessive or insufficient. For example, there may be a case where the motion training device 10B is not used due to forgetting or laziness, or a case where the number of times the motion training device 10B is used becomes excessive due to forgetting or motivation. In order to solve these problems, a function for prompting use at an appropriate time, a function for warning when the use becomes excessive, and the like may be provided.

  In the configuration described above, the positions of the left footrest portion 121 and the right footrest portion 122 are fixed, but as shown in FIG. 7, the base plate 11 is divided into a left base plate 10A and a right base plate 11B. A configuration in which the left footrest 121 is provided on the base plate 11A and the right foot rest 122 is provided on the right baseplate 11B may be employed. The left base plate 11A and the right base plate 11B are connected using a rail 18, and the distance between the left base plate 11A and the right base plate 11B is adjustable and can be adjusted at a desired distance as indicated by an arrow A. Configured to be fixed. This type of configuration is well known, and if it is the simplest configuration, a configuration using the frictional forces of the left base plate 11A, the right base plate 11B, and the rail 18 can be employed.

  If the distance between the left footrest portion 121 and the right footrest portion 122 is adjustable as in the configuration shown in FIG. 7, the position where the foot is placed can be adjusted according to the physique difference, and the posture and action for training can be adjusted. Accordingly, it is possible to adjust the position where the foot is placed.
