JP 2003-116822 A Japanese Patent Laid-Open No. 9-168529

  The technique described in Patent Document 1 reflects biological loads during exercise by detecting biological information during exercise. The exercise prescription is performed in consideration of muscles and muscle strength necessary for daily operations of the user. It cannot be set.

  On the other hand, if the technique described in Patent Document 2 is employed, the muscle strength and gait during walking of the user are measured, so an exercise prescription for strengthening the muscle strength required for walking can be considered. For this reason, there is a problem that measurement is not possible unless a dedicated device is sent to a facility equipped with a measurement device.

  The present invention has been made in view of the above-mentioned reasons, and its object is to provide an exercise prescription suitable for a user's health condition while detecting a health condition while performing daily activities in a house. It is to provide an exercise assistance system that can.

  According to the first aspect of the present invention, there is provided a sensor unit that is arranged in a house and detects a user's daily operation without being worn by the user, and output data of the sensor unit transferred through a communication network provided in the house. A health condition estimation unit that estimates the health condition of the patient, and an exercise prescription provision unit that provides an exercise prescription suitable for the user according to the health condition estimated by the health condition estimation unit.

  According to this configuration, a health condition is detected without being conscious while performing daily actions in a house, and an exercise prescription suitable for the health condition is provided. Appropriate exercise becomes possible, and exercise without excess and deficiency becomes possible. In addition, since the output data of the sensor unit is transferred to the health state estimation unit through the communication network, the sensor unit and the health state estimation unit can be arranged at a remote location, and the degree of freedom of arrangement of the sensor unit is increased. In addition, since the sensor unit can be arranged at multiple locations, it is possible to increase the amount of information used to estimate the health status by detecting various daily actions of the user, and accurately estimate the health status of the user It becomes possible to do. That is, a more appropriate exercise prescription can be given.

  The invention of claim 2 is characterized in that in the invention of claim 1, a presentation unit for presenting the exercise prescription created by the exercise prescription providing unit is provided.

  According to this configuration, since the exercise prescription is presented, it is possible to adjust the exercise so that the user himself / herself becomes an exercise with no excess or deficiency by knowing the exercise prescription. Moreover, since an exercise prescription can be confirmed, a sense of security is obtained for the user.

  According to a third aspect of the present invention, the exercise assisting device according to the first or second aspect of the present invention is provided with the exercise assisting device that causes the user to dynamically generate muscle contraction, and according to the exercise prescription created by the exercise prescription providing unit. It is characterized by driving.

  According to this configuration, since the exercise assisting device is driven in accordance with the exercise prescription, the user can exercise without any excess or deficiency without being aware of it only by using the exercise assisting device. Here, the exercise assisting device is desirably one that causes muscle contraction dynamically. The movement assisting device that dynamically generates muscle contraction has a movable part that supports a part of the user's body and has a configuration that power-drives the movable part and an electrode that is attached to the skin surface. A configuration in which muscle contraction is caused by electrical stimulation is known. The power-driven exercise assist device has a structure in which the pedal-like movable part of the bicycle rotates and the joint is bent and stretched to contract the muscle, and the position of the movable part on which the user places the foot or the buttock changes. A structure that causes muscle contraction by reflection to change the position with the center of gravity and keep balance, and by changing the load acting on the leg by moving the movable part on the stool-like movable part with the foot landing A structure for contracting muscles is known. In this type of exercise assisting device, the amount of exercise can be adjusted by adjusting exercise time, exercise intensity, exercise pattern, and the like.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the exercise assisting device includes a footrest portion on which a user in a standing posture places his / her foot and a footrest portion so as to cause muscle contraction in the leg portion of the user. And a drive mechanism section that changes the position of the footrest section by power driving.

  According to this configuration, when the footrest portion is moved back and forth or right and left (at least one of straight advance and tilt), the user contracts the leg muscles to maintain balance. Further, if the footrest portion is moved up and down while holding a handrail or the like, an operation such as squat or stepping becomes possible, and the muscles of the user's leg can be contracted. Moreover, since the leg muscles contract while the user is standing, there is no need to take a posture to exercise or to hold an exercise device, and it is easy to exercise while standing. Even if there is no strong motivation for exercise, the opportunity to exercise can be increased.

  According to a fifth aspect of the present invention, in the third aspect of the invention, the exercise assisting device includes a support unit on which a user in a sitting posture places a buttocks, a footrest portion on which the user places a foot, and a foot on the footrest portion. And a drive mechanism for changing the position of the support by driving the support so that the ratio of the load on the user placed on the leg is changed. Regardless of the movement, the knee joint is moved so as to cause muscle contraction while keeping the bending angle of the knee joint constant.

  According to this configuration, the user can use in a sitting posture sitting on the support portion, and the load on the leg portion is light, so even a user with weak leg strength can use it. Further, muscle contraction is generated in the leg while keeping the bending angle of the knee joint constant, so that even a user who has pain in the knee joint can use it without increasing the pain due to bending and stretching of the knee joint.

  According to a sixth aspect of the present invention, in any of the first to fifth aspects of the invention, the health state estimation unit is identified by identifying the user from the daily operation of the user detected from the output data of the sensor unit. The exercise prescription providing unit provides an exercise prescription for each user identified by the health state estimation unit.

  According to this configuration, even when there are a plurality of users, each user can be identified from daily operations, and an exercise prescription for each identified user can be provided.

  According to the configuration of the present invention, since the user can detect the health condition while performing daily activities in the house, there is an advantage that the health condition is intentionally detected without using various measuring instruments. is there. In addition, since an exercise prescription suitable for the detected health condition is provided, there is an advantage that even a user who does not have knowledge about the exercise prescription can perform appropriate exercise and exercise without excess or deficiency.

  In the present embodiment, a daily motion of a householder (user) in a house is mainly detected by a sensor unit in a house, and the health state of the user is estimated from output data of the sensor unit, and exercise according to the estimated health state The prescription is provided to the user. As a sensor unit that detects the user's daily movements, a TV camera that captures the user's daily movements, detects infrared rays emitted or received from the human body, and detects user movements by changing the amount of received light An infrared sensor that detects the load, a load sensor that detects a load acting on a floor or a handrail in the house, and the like can be used.

  In the present embodiment, a case where a load sensor is used as a sensor unit is exemplified, and various information relating to the daily operation of the user is detected by a change in the load acting on the load sensor, and the health state of the user is estimated from the information. It shall be. When a TV camera is used, the user is separated from the background and recognized by image processing from the captured image, and the health state is estimated by classifying the user's behavior pattern. When an infrared sensor is used, the movement speed and posture of the user are detected from the change pattern of the amount of received light, and the health state of the user is estimated using these pieces of information. Moreover, if a plurality of types are used in combination as the sensor unit, the reliability of estimation regarding the health condition can be improved by using a large amount of information.

  In the embodiment described below, as shown in FIG. 2, in the house HS, the floor load sensor 1a is arranged on the floor FL (including the tread surface of the stairs) and the handrail HN (the handrail in the hallway is shown). The handrail load sensor 1b is disposed on a staircase handrail as shown in FIG.

  A plurality of floor load sensors 1a are provided and are arranged so as to detect the stride when the user H is walking. For example, if a plurality of floor load sensors 1a are arranged apart from each other on one floor material, the position where the load is applied can be calculated from the distribution of the load acting on each floor load sensor 1a. , Stride and step can be obtained by position change. Further, the handrail load sensor 1b only needs to be able to detect the load acting on the handrail HN. However, the minimum structure may be one, but by detecting the load with a plurality of handrail load sensors 1b and obtaining an average value, etc. The reliability of the measured value of the load acting on HN can be increased. By using a plurality of handrail load sensors 1b, it is also possible to calculate a position where a load is applied to the handrail HN.

  In addition, if the floor material for houses which provided the floor load sensor 1a beforehand and the handrail member for houses which provided the handrail load sensor 1b beforehand are used, the effort which attaches the floor load sensor 1a and the handrail load sensor 1b at the time of construction will be saved. It becomes construction.

  As shown in FIG. 1, the floor load sensor 1a and the handrail load sensor 1b constitute a sensor unit 1 together with a communication unit 1c that transfers output data of the floor load sensor 1a and the handrail load sensor 1b by data communication. The communication unit 1c A / D converts the output data of the floor load sensor 1a and the handrail load sensor 1b and compresses the data, and gives an identification code and a detection time for each output data of the floor load sensor 1a and the handrail load sensor 1b. Packetize. Therefore, the time series data of the load detected by each floor load sensor 1a and each handrail load sensor 1b can be transmitted as a packet.

  The output data of the sensor unit 1 is transferred to the server 2 through the communication network 5 laid in the house HS. The server 2 is a computer and is installed in the house, and estimates the health state of the user H using the output data of the sensor unit 1. In this embodiment, the health state of the user H basically means a state of muscular strength, but whether or not there is a leg disorder (injury or pain) and whether or not he / she can walk (whether he / she has fallen). Such information can also be estimated as a health condition.

  Now, if we focus on muscle strength, if the height of lifting the foot from the floor FL during walking decreases due to the decrease in the muscle strength of the user H, it will be easier to hit a small step, and as a result, it will be easier to tip over. If it becomes, the exercise | movement which strengthens the muscular strength for a walk will be needed. The decrease in muscle strength required for walking can also be estimated from the walking posture and stride, and the muscle strength required for walking decreases if the posture is bent forward during walking or if the stride is less than a predetermined percentage of the height. I can say that.

  As shown in FIG. 3, whether or not the body is in a forward bending posture is determined from the ratio between the load acting on the handrail HN such as the stairs and the corridor and the load acting on the floor (including the tread of the stairs). Can be estimated. In other words, if the muscle strength of the legs decreases, the arm strength is used not only by the leg strength but also by the handrail, so that it bends forward as shown in FIG. 3 (a), while the muscle strength of the legs and lower back is appropriate. For example, as shown in FIG. Therefore, the posture during walking can be estimated by using the ratio between the load detected by the floor load sensor 1a and the load detected by the handrail load sensor 1b. When the position where the user H has the handrail HN can be detected by the handrail load sensor 1b, the relationship between the position of the foot detected by the floor load sensor 1a and the position of the hand detected by the handrail load sensor 1b is used. It is possible to estimate the posture during walking.

  The server 2 includes a sensor information processing unit 2a for estimating the health state of the user H, and the sensor information processing unit 2a extracts features of load change patterns included in time-series data transferred from the sensor unit 1. I do. For example, since information known as floor reaction force is obtained from the floor load sensor 1a, a plurality of types of feature parameters are extracted from the change pattern of the floor reaction force. Since the extracted feature parameters are digitized, information such as the right one step time, the left one step time, the right step length, the left step length, and the step length can be obtained by collating with known data stored in the health state estimation unit 2b. Obtainable. Further, from the floor reaction force, the weight of the user H, the kicking force during walking, and the like can be obtained. The health state estimation unit 2b uses a configuration in which feature parameters are collated with known data stored in a database. When the health parameters of the user H are classified into a plurality of types using the feature parameters, a neural network is used. A configuration using may be adopted.

  As described above, the health condition estimation unit 2b extracts information such as the right one-step time, the left one-step time, the right stride, the left stride, the step, the weight, and the like. The user H can be distinguished by the walking habit or weight of H. Therefore, if information for each user H is taught in advance using a neural network or the like as a classifier, the user H can be specified by the output data of the sensor unit 1. Therefore, when there are a plurality of users H, the health state estimation unit 2b stores the health state obtained for each user H in association with the user H. Since the health status history can be determined by accumulating the health status for each user H in this way, the possibility of a change in muscle strength or the possibility of injury (injury or pain) is determined based on the fluctuation tendency of the health status. It becomes possible to do.

  When there are a plurality of people in one place, it is difficult to distinguish the information for each user H (the output data of the floor load sensor 1a and the output data of the handrail load sensor 1b). It is difficult to find the state. Therefore, when the presence of a plurality of persons is recognized based on body weight, it is desirable that the health state estimation unit 2b does not estimate the health state.

  The server 2 is also provided with an exercise prescription providing unit 2c that determines the operation of the exercise assisting device 3 described later. The exercise prescription providing unit 2c provides a combination of exercise type, exercise intensity, exercise time, and the like suitable for the user H as an exercise prescription according to the health state estimated by the health state estimation unit 2b. In the exercise prescription providing unit 2c, exercise prescriptions associated with various health states estimated by the health state estimation unit 2b are registered in advance, and estimation results obtained by the health state estimation unit 2b are obtained. Select and output an exercise prescription corresponding to the result. The server 2 is provided with a communication unit 2d for connecting to the communication network 5.

  As is clear from the above-described configuration, the user H detects a daily motion during walking while walking in the hallway or staircase in the house HS, and the health data is output from the output data of the sensor unit 1. Since the state is estimated, it is not necessary for the user H to wear a measuring instrument for measuring the health state, and the health state is measured without being conscious during daily operations. In addition, since the sensor unit 1 that detects daily operations and the server 2 that estimates the health state transfer data through the communication network 5, the sensor unit 1 and the server 2 can be arranged at remote locations, The degree of freedom of arrangement of the sensor unit 1 is increased. In addition, by arranging the sensor units 1 at multiple locations, it is possible to increase the amount of information used for detecting the user's daily activities and accurately estimate the user's health condition.

  The health condition of the user H obtained by the health condition estimating unit 2b and the exercise prescription provided by the exercise prescription providing unit 2c can be displayed on the display unit 6a as a presentation unit using a liquid crystal display or the like. The display unit 6a is arranged in parallel with an operation unit including a switch (not shown), and calls the health prescription accumulated in the health state estimation unit 2b and the exercise prescription provided by the exercise prescription provision unit 2c by operating the operation unit. Can be displayed on the display unit 6a. In the illustrated example, a configuration in which the display unit 6a is connected to the communication network 5 via the communication unit 6b is adopted and the display unit 6a is separated from the server 2. However, the display unit 6a may be provided in the server 2. Is possible. The operation unit may not be arranged in parallel with the display unit 6a. For example, if the display unit 6a is used as a touch panel and also serves as the operation unit, the necessary information is displayed by touching the screen of the display unit 6a. Can be displayed. Since the health condition estimated by the health condition estimation unit 2a and the exercise prescription provided by the exercise prescription providing unit 2c are displayed on the display unit 6a, the user H can check the health condition and the exercise prescription by himself / herself. Note that the presenting unit is not limited to the display unit 6a, and a configuration in which a health condition or an exercise prescription is printed out using a printer or a configuration in which advice is given by voice may be employed.

  The exercise prescription provided from the exercise prescription providing unit 2c includes control data of the exercise assisting device 3. Although various types of exercise assisting devices 3 can be used, a configuration that causes the user H to cause muscle contraction passively is used. In other words, causing the muscle contraction dynamically means that the user H does not exert muscle strength consciously but causes the user H to automatically generate muscle contraction by the operation of the exercise assisting device 3. This type of exercise assisting device 3 includes a movable part that supports a part of the body of the user H, a power drive of the movable part, an electrode that is attached to the skin surface, and a muscle by electrical stimulation. There is a configuration that causes contraction.

  As an exercise assistance device that is driven by power, it has a movable part that rotates like a pedal of a bicycle, and it has a structure that uses muscles and contracts by bending and stretching the joint as the movable part rotates by placing a foot or hand on the movable part A structure in which a person has a movable part on which a foot or a buttock is placed and the position of the movable part changes so that the position of the fulcrum and the center of gravity changes, and the muscles contract by reflection to maintain the balance. For example, there is a configuration in which the heel portion is placed on the movable portion and the movable portion is moved to change the load acting on the leg portion to contract the muscle.

  In the present embodiment, the muscle is contracted by reflex that is used in a standing posture to keep balance and the leg is acted on by changing the position of the buttock while using the sitting posture with the foot landing. The structure which changes the load to perform is illustrated. Both configurations include a drive mechanism unit 3b that includes a power source such as a motor and that drives the movable unit 3a. Moreover, the control part 3c which controls the driving | running time by the drive mechanism part 3b, an exercise speed, and an operation pattern by providing control data is provided. The control unit 3c is connected to the communication network 5 via the communication unit 3d, and can receive control data included in the exercise prescription from the exercise prescription providing unit 2c.

  An information providing unit 4 is connected on the communication network 5, and the information providing unit 4 is provided with a database 4a connected via the communication unit 4b. In this database 4a, various exercise prescriptions are stored regardless of the health condition of the user H, and this exercise prescription can be read and the exercise assisting device 3 can be operated or presented to the presentation unit. It is.

  FIG. 4 shows an exercise assisting device 3 used in a standing posture, and has a device main body 7 provided with a footrest portion 7b as a movable portion 3a on a base (not shown). In the illustrated example, the base is fixed to the floor FL so as to be embedded in the floor FL, and the footrest portion 7b has an endless belt shape and can move the upper surface in the left-right direction. That is, it has a shape in which the endless belt of the treadmill is arranged in the left-right direction instead of the front-rear direction. Further, the footrest portion 7b is power-driven so as to reciprocate left and right by the drive mechanism portion 3b.

  In the illustrated example, the apparatus main body 7 is installed in front of the bathroom vanity CB. Therefore, when the user H grips the handrail HN provided on the vanity CB and starts the operation of the apparatus body 7 in a state of being placed on the footrest 7b, the foot that is a fulcrum that supports the load of the user H The positional relationship with the position of the center of gravity of the user H changes, and the user H contracts muscles such as the leg, abdomen, and back of the waist by reflexes that try to maintain balance.

  When the apparatus main body 7 is installed in front of the vanity table CB as shown in the drawing, the user H is placed on the movable part 3a without being aware of the time of washing, so the apparatus main body is simply turned on. It is possible to perform other dynamic movements simply by starting the operation of No. 7. If the switch is provided on the handrail HN, it is convenient because it can be operated while holding the handrail HN. Moreover, since the handrail HN is used and used, the user H can exercise safely without falling down. Moreover, since the handrail HN is provided on the vanity table CB installed in the house HS, the installation space of the apparatus main body 7 can be reduced as compared with the case where the handrail is provided on the apparatus main body 7.

  In addition, the handrail HN which the user H hold | grips at the time of an exercise | movement may be provided not only in the bathroom vanity CB but in other facilities, such as a system kitchen, and may be provided in the wall etc. of the house HS. In either case, the handrail HN is provided at a position where the user H who uses the apparatus main body 7 can hold it. The apparatus main body 7 is not necessarily limited to being embedded in the floor FL, but may be fixed on the floor FL, or may be mounted on the floor FL without being fixed to the floor FL. When the handrail HN is integrally provided in the apparatus main body 7 configured to be placed on the floor FL, when the user H is placed on the footrest portion 7b, a lateral load acts on the handrail HN and the apparatus main body 7 can fall down. However, the apparatus main body 7 can be used safely by separating the handrail HN from the apparatus main body 7 and providing the handrail HN in the equipment installed in the house HS or the house HS as in this embodiment. Can do.

  In the above example, the footrest portion 7b is reciprocated left and right. However, the footrest portion 7b is configured to reciprocate back and forth or up and down, or the tilt angle in the front and rear direction or left and right direction changes. A configuration or a configuration that reciprocates around the vertical axis may also be adopted. Alternatively, an operation of combining any two or more of these may be employed.

  The exercise assisting device 3 used in the sitting posture has a configuration shown in FIG. In this configuration, a footrest portion 7b on which the user H puts one foot is provided on the base 7a, and further, a seat-like shape that supports the buttocks of the user H who placed the foot on the footrest portion 7b. A support portion 7c is provided. The support portion 7c is driven so as to change the tilt angle by the drive mechanism portion 3b provided at the upper end portion of the support leg 7d erected on the base 7a. Further, the footrest portion 7b is also driven so that its position changes in synchronization with the tilting of the support portion 7c by the drive mechanism portion 3b. That is, the foot placement part 7b and the support part 7c become the movable part 3a.

  This configuration is intended to contract the muscles of the legs without flexing or stretching the knee joint of the user H, and acts on the footrest 7b by changing the inclination angle of the support 7c. The ratio between the load of the user H and the load of the user H acting on the support portion 7c is changed, and as a result, the load acting on the leg portion of the user H is changed. Further, the position of the footrest portion 7b is changed in conjunction with the support portion 7c so that the knee joint angle does not change even if the inclination angle of the support portion 7c changes. Furthermore, the direction in which the support portion 7c is inclined is a direction in which a shearing force does not act on the knee joint, and this operation can be used even by the user H having knee pain.

  It should be noted that load sensors are arranged on the footrest portion 7b and the support portion 7c, and the force sensor's output data is applied to the leg link model to estimate the force acting on the knee joint, and the knee joint is sheared. It is also possible to adopt a configuration in which the drive mechanism unit 3b is feedback-controlled so that no force acts. Alternatively, a configuration may be adopted in which a restoring force by an appropriate spring is applied to the footrest portion 7b to change only the inclination angle of the support portion 7c. Even in this case, if a spring that applies a restoring force to the footrest 7b is appropriately designed, it is possible to change the load acting on the leg without bending or stretching the knee joint. In the configuration shown in FIG. 5, the handrail HN is provided at the upper end of the support column 7e erected on the base 7a. However, even if the handrail HN is provided on the wall or equipment of the house HS as in the configuration example shown in FIG. Good.

  In the embodiment described above, the floor load sensor 1a and the handrail load sensor 1b are used as the sensor unit 1. However, when the server 2 detects the load change pattern from the output data of the floor load sensor 1a, the handrail load is detected. It is possible to estimate the user's posture from the load movement change pattern without providing the sensor 1b.

It is a block diagram which shows embodiment of this invention. It is a schematic block diagram same as the above. It is a figure which shows the usage example same as the above. It is a perspective view which shows an example of the exercise assistance apparatus used for the same as the above. It is a perspective view which shows the other example of the exercise assistance apparatus used for the same as the above.
