Description

The present invention relates to a vibration training device and a vibration application method.

In recent years, due to changes in the disease structure such as an increase in lifestyle-related diseases and the aging of the population, the gap between the healthy life expectancy and the average life expectancy is widening. Even though average life expectancy has increased, the number of elderly people who have difficulty living independent and healthy lives is increasing due to heart disease, cerebral infarction, being bedridden due to falls and fractures, and dementia. Therefore, extending healthy life expectancy by narrowing the gap between average life expectancy and healthy life expectancy is an important national issue, and establishing more effective rehabilitation is essential. In order to solve the above problems, vibrations are applied to the muscles of the user (for example, a person in need of care), and the muscle strength of the user, etc. can be improved more easily and effectively than normal rehabilitation using only vibration stimulation. There is a dynamic exercise therapy device that can improve metabolic function, bone mass, and associated motor function. This applies acceleration to the body through vibration stimulation to amplify the effects of muscle training, improves balance function by stimulating sensory organs, increases bone mass, etc., even when the user does not move. It uses principles that trigger various physiological responses. Therefore, compared to normal exercise, it is attracting attention because it is extremely safe and can safely provide rehabilitation to disabled people and frail elderly people (for example, Patent Document 1 and Patent Document 2).

Special Publication No. 2009-502319 Special Publication No. 2008-517679

By the way, the dynamic exercise therapy device described in Patent Document 1 stimulates the patient's muscle strength by having the patient stand on a platform (corresponding to a vibrating plate) and applying vibration to the platform. . In addition, in the case of a patient who has difficulty standing, the dynamic exercise therapy device applies vibrations to the platform while the patient is sitting on a seat provided on the platform, thereby improving the patient's muscle strength. It is said to be stimulating.

The dynamic exercise therapy device described in Patent Document 1 mentioned above measures the patient's weight in advance using a scale or the like, and sets the measured weight as the apparent weight. Further, the exercise therapy device measures the load applied to the vibrating plate as a deviation value based on the apparent body weight using an accelerometer (corresponding to a processing device). The obtained deviation value is converted into a corresponding mechanical vibration energy transmission rate based on a look-up table (comparison table).

However, the dynamic exercise therapy device described in Patent Document 1 uses an accelerometer to obtain the load applied to the vibrating plate as a deviation value based on the apparent body weight, so it directly vibrates. It is not possible to measure the load applied to the plate. In addition, the dynamic exercise therapy device uses the state where the patient is completely on the vibrating plate (the patient's entire weight is applied to the vibrating plate) as a standard (apparent weight), and calculates the value of the deviation from the standard. It is supposed to be measured. Therefore, when the patient is placed on the dynamic exercise therapy device when the vibrating plate is in a non-vibrating state, the patient's actual weight and apparent weight are approximately the same, so no acceleration occurs. Therefore, when the vibrating plate is in a non-vibrating state, there is a problem in that the load (actual weight of the patient) cannot be measured.
Healthy people train voluntarily, so they adjust the load on their bodies by themselves. On the other hand, training for elderly people and patients who are likely to be accompanied by a trainer is not spontaneous, but is conducted using methods based on medically proven protocols.
When performing this on elderly patients or post-operative patients, it is important to measure the load on the lower limbs while the user maintains a proper sitting posture, and for the accompanying trainer to recognize the extent of the load. It is important to train by checking the amount of change in load when changing the load, but there is also the problem that this cannot be achieved with conventional techniques such as the dynamic exercise therapy device described in Patent Document 1.

In addition, the dynamic exercise therapy device described in Patent Document 1 calculates the deviation value based on the apparent body weight as described above, and does not use the actual body weight as the standard, so there may be errors in measurement. Easy to occur. Therefore, it is difficult to accurately apply vibrations (accelerated motion) to the patient. In addition, the dynamic exercise therapy device converts the deviation value into the transmission rate of mechanical vibration energy indirectly using a lookup table, making it difficult to increase the sampling frequency and causing measurement errors. There are some problems that can easily occur. In addition, since the dynamic exercise therapy device is based on the apparent body weight, if the user places only a part of the body (for example, the feet) on the vibration plate, it is necessary to apply an appropriate load to the user's feet. There was a problem that vibration could not be applied. As described above, in the dynamic exercise therapy device, it is necessary to separately measure the apparent weight using a scale. However, for example, in the case of a person in need of care who has difficulty standing on a scale, it is necessary to measure the weight in advance and calculate it using a look-up table, which poses a problem. Furthermore, the calculated value changes greatly depending on posture and the state of tension in the lower limb muscle strength (for example, even in the same sitting posture, the load on the lower limb changes greatly depending on the degree of tension in the quadriceps, soleus, and tibialis anterior muscles). Even people of the same height and weight have different loads, and a lookup table alone cannot adequately handle this.

Further, the vibration stimulation device (device that stimulates the human body by vibration) described in Patent Document 2 cannot measure the load related to the vibration plate (diaphragm). Therefore, it has the same problem as Patent Document 1.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vibration training device and a vibration application method that can measure loads in a non-vibration state and a vibration state. Another object of the present invention is to provide a vibration training device and a vibration application method that can display load changes in a non-vibration state and a vibration state.

(1) The vibration training device of the present invention, which is provided to solve the above-mentioned problems, includes a vibration plate on which a user places his or her feet, a vibration generation unit that applies vibration to the vibration plate, and a vibration training device that applies vibration to the vibration plate. a support base disposed on the lower side; an elastic member disposed between the support base and the vibrating plate and urging the vibrating plate upward while supporting the vibrating plate from the lower surface side; A displacement meter disposed on the lower side of the vibrating plate in an area avoiding an area where the elastic member and the vibration generating unit are disposed, and a calculation section for calculating the amount of displacement detected by the displacement meter. The displacement meter is capable of detecting the displacement amount of the vibrating plate in the vertical direction with a height when the vibrating plate is in a non-vibrating state as a first position, and the calculating unit is configured to detect the vertical displacement amount of the vibrating plate. The present invention is characterized in that the load applied to the vibrating plate can be calculated based on the amount of displacement from the first position.

The vibration training device described above is capable of detecting the amount of displacement of the vibration plate in the vertical direction using a displacement meter, with the height when the vibration plate is in a non-vibration state being the first position. That is, the vibration training device described above is capable of detecting the amount of vertical displacement of the vibration plate in a non-vibration state. Therefore, the vibration training device described above can calculate the load applied to the vibration plate based on the detected displacement amount. Thereby, the vibration training device described above can measure loads (for example, the user's weight or the weight of a part of the body) even in a non-vibration state, which could not be measured conventionally. Therefore, there is no need to measure the user's weight (apparent weight) in advance, so there is no need for, for example, elderly people, people in need of care, etc. to take the trouble to separately weigh themselves on a scale. This can be expected to reduce the burden on the user and the caregiver. Note that various types of displacement meters, such as contact type and non-contact type, can be used as the displacement meter.

In addition, the vibration training device described above can calculate the load applied to the vibration plate based on the amount of displacement from the first position, so even when applying vibration to the vibration plate, the vibration training device can calculate the load applied to the vibration plate based on the first position. It is possible to calculate the load applied to the Further, the above-described vibration training device can calculate the load without using a lookup table (comparison table), so the trainer can visually check it. Further, the vibration training device described above can improve the accuracy of load measurement.

(2) The vibration training device of the present invention described above may include a display device that directly or indirectly displays either or both of the load and the displacement amount.

With this configuration, the vibration training device described above can visually provide a target value (guideline) when applying vibration to a user (for example, an elderly person or a person in need of care). . Therefore, the above-mentioned vibration training device can apply vibration to the user based on accurate load and displacement amount, and can obtain an appropriate training effect (effect due to muscle stimulation). Further, the above-described vibration training device can be expected to improve the convenience of an assistant (eg, a physical therapist or a trainer) who assists the user in training, for example.

(3) In the above-described vibration training device of the present invention, the calculation unit is configured to move from the first position to the second position, with the user placing his or her feet on the vibration plate in a non-vibrating state as a second position. A reference load can be calculated based on the amount of displacement to the position, and the display device can directly or indirectly display a load change with respect to the reference load when the vibrating plate is in a non-vibrating state and a vibrating state. It would be good if it were.

With this configuration, the vibration training device described above can calculate the reference load in a non-vibration state in the calculation section. Here, the reference load is the user's body weight if the user applies the entire body weight, and if the user applies the load by placing only the foot on the vibrating plate, for example, the reference load is the load (load due to the foot). becomes. The reference load changes depending on the seat position, the position of the sole of the foot, and the state of lower limb muscle strength, but it can be measured (the seat position changes depending on the horizontal distance from the sole of the foot and the distance in the height direction) However, it also varies depending on the user's physical condition and training purpose). Therefore, when the vibration training device described above changes the vibration plate from a non-vibrating state to a vibrating state, the display device displays the load change in the vibrating state based on the reference load (load amount) in the non-vibrating state. I can do it. Vibration training devices have different effects on the body depending on the amount of load. For example, when the amount of load is low, the effect of improving balance function due to sensory stimulation is obtained, and when the amount of load is increased, the effect of increasing muscle strength is obtained. In other words, by appropriately managing the load amount, the above-mentioned vibration training device can appropriately apply vibration to the user based on accurate load changes, resulting in an appropriate training effect (muscle stimulation). effect, balance improvement effect, blood flow improvement effect, etc.). Furthermore, an assistant (for example, a physical therapist or a trainer) who assists the user in training can objectively convey the effects of the vibration training device to the user. Further, since it is difficult for many users such as frail elderly people to increase the load themselves, changes in the amount of load itself are useful in determining the effectiveness of vibration training. By objectively observing the load amount, it is possible to establish a training protocol for each user, which may also lead to the establishment of evidence for developing effective rehabilitation methods.

(4) In the above-described vibration training device of the present invention, it is preferable that the displacement meter is located below the center of gravity of the vibration plate.

With this configuration, the vibration training device described above can detect displacement using a displacement meter at a position where the influence of vibration is small (for example, by disposing the displacement meter on a plate that dampens vibrations). That is, since the center of gravity of the vibrating plate does not swing in any direction other than the vertical direction when the vibrating plate vibrates, the amount of displacement in the vertical direction can be detected with high accuracy. Therefore, it is possible to calculate the load with high accuracy. Further, the center of gravity of the vibrating plate may be made to coincide with the center in the horizontal direction of the area where each elastic member is arranged, for example. This suppresses vibration in directions other than the vertical direction when the vibration plate vibrates.

(5) In the above-described vibration training device of the present invention, the calculation unit calculates the load by processing data related to the plurality of displacement amounts detected in a predetermined time using a moving average method. good.

With this configuration, the vibration training device described above can calculate a load with high accuracy by averaging using the moving average method, for example, without increasing the number of samplings more than necessary. Therefore, the vibration training device described above can reduce the load on the calculation section.

(6) In the vibration training device of the present invention described above, it is preferable that the displacement meter is a non-contact displacement meter.

By having such a configuration, the above-described vibration training device can increase the degree of freedom in arranging the displacement meter. Here, for example, a laser displacement meter can be used as the non-contact displacement meter.

(7) The vibration imparting method of the present invention, which is provided to solve the above-mentioned problems, includes a vibrating plate on which a user places his or her feet, a vibration generating unit that imparts vibration to the vibrating plate, and a vertical direction of the vibrating plate. a displacement meter that measures the amount of displacement to, a calculation unit that calculates a load by calculating the amount of displacement, and a display that directly or indirectly displays either or both of the load and the amount of displacement. a first position setting step of setting the height of the vibration plate as a first position in a non-vibration state before the vibration generation unit generates vibration, using a vibration training device comprising a vibration training device; a second position measuring step of measuring, as a second position, a position displaced from the first position with the user's foot placed on the vibrating plate; and moving from the first position to the second position. a standard load calculating step of calculating a standard load based on the amount of displacement of the vibration generating unit; a vibration generating step of applying vibration to the vibrating plate by the vibration generating unit to bring it into a vibrating state; and a vibration generating step of calculating a load in the vibrating state. It is characterized by executing a state load calculation step and a display step of directly or indirectly displaying either or both of the load in the non-vibration state and the vibration state and the load change with respect to the reference load. It is something to do.

In the above-described vibration imparting method, the height of the vibrating plate in the non-vibrating state can be set as the first position by the first position setting step. That is, the no-load state of the vibrating plate is set as the first position. Note that the first position may be set manually or automatically. Further, in the above-described vibration imparting method, a position displaced from the first position when the user's foot is placed on the vibration plate can be measured as the second position by the second position measurement step. Further, in the above-described vibration applying method, the reference load can be calculated based on the amount of displacement from the first position to the second position by the reference load calculation step. That is, it is possible to measure the load (reference load) applied to the vibrating plate by the user in a non-vibrating state. Thereby, the above-described vibration application method can measure the load (for example, the user's weight or the weight of a part of the body) even in a non-vibration state, which could not be measured conventionally. Therefore, there is no need to measure the user's weight (apparent weight) in advance, so there is no need for, for example, elderly people, people in need of care, etc. to take the trouble to separately weigh themselves on a scale. This can be expected to reduce the burden on the user and the caregiver. Note that displacement in each step may be detected using, for example, a non-contact displacement meter.
Note that it is also possible to measure the load in a vibrating state in the training posture without calculating the reference load based on the amount of displacement from the first position to the second position.

Further, in the above-described vibration imparting method, vibration can be imparted to the vibrating plate through the vibration generating step. As a result, the above-described vibration application method can apply vibration to the user while the reference load is applied to the vibration plate. Further, in the vibration application method described above, the load in the vibration state can be calculated by the vibration state load calculation step. Further, in the above-described vibration applying method, the load change with respect to the reference load can be directly or indirectly displayed in the non-vibration state and the vibration state by the display step. As a result, the vibration application method described above can appropriately apply vibration to the user based on accurate load changes, and can produce appropriate training effects (muscle stimulation effects, balance improvement effects, blood flow effects, etc.). improvement effects, etc.). Moreover, the above-described vibration application method can be expected to improve the convenience of an assistant (eg, a physical therapist or a trainer) who assists the user in training, for example.

According to the present invention, it is possible to provide a vibration training device and a vibration application method that can measure loads in a non-vibration state and a vibration state. Further, according to the present invention, it is possible to provide a vibration training device and a vibration application method that can display load changes in a non-vibration state and a vibration state.

An embodiment of the vibration training device 1 according to the present invention will be described in detail below with reference to FIGS. 1 to 7.

As shown in FIG. 1, the vibration training device 1 includes a plurality of wheels 2, a main body cover 3 supported on the wheels 2, a column 4, a handle 5, an operation panel 6, a vibration plate 20, etc. is formed. In addition, as shown in FIGS. 2(a) and 2(b), the vibration training device 1 includes, in addition to the above, a support base 10, a vibration generation unit 100, an elastic member 30, a displacement meter 40, and a controller. 50, etc.

The main body cover 3 is divided into an upper cover 3a and a lower cover 3b. A vibration plate 20 is arranged on the upper surface side of the upper cover 3a. The lower cover 3b is supported by the wheels 2 and is movable in the horizontal direction integrally with the wheels 2.

The support base 10 is disposed below the vibrating plate 20, and horizontally disposed above the bottom surface of the lower cover 3b with a space therebetween. The support base 10 is formed in a square shape, and the four corners are chamfered (see FIG. 3). The support base 10 is supported via rubber 11 fixed on the lower cover 3b. The rubber 11 suppresses vibrations from being transmitted to the floor surface. The support base 10 supports a vibration generating unit 100 and an elastic member 30, which will be described later. A vibration generating unit 100 and an elastic member 30 are supported above the support base 10. Further, the support base 10 has an opening 12 formed in the center thereof, and a displacement meter 40, which will be described later, is arranged so as to pass through the opening 12.

The vibration generating unit 100 is supported near the center on the support base 10 and is located below the center of the vibration plate 20. As shown in FIG. 4, the vibration generating unit 100 uses a motor 101 as a drive source and converts the rotation of the motor 101 into vertical vibration. Although various motors such as an inverter motor, a servo motor, and a stepping motor can be used as the motor 101, in this embodiment, for example, a DC brushless motor is used. The vibration generating unit 100 consists of fixed plates 102 , 102 (the fixed plate 102 on the front side is not shown) that are erected at intervals, a bottom plate 108 , a motor 101 supported by the fixed plate 102 , and a motor 101 . It includes a propeller shaft 103 connected to a motor shaft and two rotating shafts 104, 104. The rotating shafts 104, 104 are arranged on both sides in the width direction (left and right direction in the figure) with the propeller shaft 103 interposed therebetween. The rotating shafts 104, 104 are rotatably supported between the fixed plates 102, 102, respectively. The upper end sides of the fixed plates 102, 102 are fixed to the lower surface side of the vibration plate 20. Further, the bottom plate 108 is fixed on the support base 10.

The vibration generating unit 100 includes a driving pulley 110 fixed to a propeller shaft 103 so as to be rotatable together, and driven pulleys 111, 111 fixed to respective rotary shafts 104, 104 so as to be rotatable together. The drive pulley 110 can rotate in synchronization with the rotation of the motor 101. Further, a timing belt 112 having teeth formed on both surfaces is stretched around the drive pulley 110 and the driven pulleys 111, 111. The timing belt 112 can transmit the rotation of the drive pulley 110 to the driven pulleys 111, 111. In this embodiment, the timing belt 112 is stretched around the driven pulleys 111, 111 so that as the drive pulley 110 rotates, the driven pulleys 111, 111 rotate synchronously in opposite directions. Therefore, as the driven pulleys 111, 111 rotate, the rotating shafts 104, 104 rotate in synchronization with each other in opposite directions. In this embodiment, the two rotating shafts 104, 104 are configured to rotate synchronously in opposite directions by one motor 101. The rotating shafts 104, 104 may rotate in synchronization with each other in opposite directions. In such a case, the two motors may be rotated with the rotating shafts 104, 104 synchronously rotated in opposite directions using an inverter or the like.

Since the above-mentioned rotating shafts 104, 104 are provided symmetrically, one side will be explained below. A first weight body 105 is fixed to the distal end side of the rotating shaft 104 so as to be rotatable integrally with the rotating shaft 104 . Further, a second weight body 106 is fixed to the base end side of the rotating shaft 104 (on the driven pulley 111 side) so as to be rotatable integrally with the rotating shaft 104. Further, a third weight body 107 is rotatably supported at the intermediate portion of the rotating shaft 104 . The first weight body 105 and the second weight body 106 are made of iron, for example. The third weight body 107 is made of aluminum, for example. Note that the first weight body 105, the second weight body 106, and the third weight body 107 can be formed of various materials depending on the vibration to be applied.

A drive pin (not shown) is provided on the surface of the rotating shaft 104. The drive pin protrudes in the radial direction of the rotating shaft 104 and can engage with the third weight body 107. The third weight body 107 can rotate integrally with the rotating shaft 104 by engaging with the drive pin.

Here, when the rotating shaft 104 rotates in one direction (direction a in FIG. 4), the third weight body 107 is connected to the first weight body 105 and the second weight body by a drive pin (not shown). 106, and the centrifugal force of the first weight body 105 and the second weight body 106 is reduced, thereby weakening vibration in the vertical direction. On the other hand, when the rotating shaft 104 rotates in the opposite direction (direction b in FIG. 4), the third weight body 107 is separated from the first weight body 105 and the second weight body 106 by the drive pin. The centrifugal force of the first weight body 105 and the second weight body 106 is increased by being held in a position facing the same direction, thereby intensifying the vibration in the vertical direction. The vibrations generated by the vibration generating unit 100 are transmitted to the vibration plate 20.

As shown in FIG. 1, the support column 4 is erected on the front end side of the upper cover 3a. The column 4 is provided with a handle 5 and an operation panel 6 on the upper end side.

The handle 5 is formed into a U-shape as a whole by having the front side formed in a straight line along the width direction and the both ends in the width direction protruding toward the rear. The user M (see FIG. 6) can take a posture suitable for training by gripping the handle 5 at an appropriate position. The handle 5 can be formed into various shapes depending on the type of use, and can be made movable if necessary.

The operation panel 6 is formed of, for example, a touch panel. In this embodiment, the operation panel 6 includes a display device 60 and an input section 61. The display device 60 can display, for example, operation buttons as the input section 61 and various setting screens in the vibration training device 1. Furthermore, the display device 60 can display various types of information such as the amount of displacement of the vibrating plate 20 and the load W applied to the vibrating plate 20, which will be described later. Details of the specific display on the display device 60 will be described later.

The input unit 61 is, for example, an operation button displayed on a touch panel. The operation buttons include, for example, a start button to start training (vibration generation), a button to stop training (vibration generation), a setting button to set the vibration conditions (frequency, amplitude, etc.) of the vibrations applied during training, and a button to set the training time. It has various buttons such as setting buttons to change. Further, the input unit 61 can be arranged in a place other than the touch panel as not only an operation button displayed on the touch panel but also various buttons such as an emergency stop button.

Here, the amplitude can be adjusted in two steps, high or low, and the frequency can be adjusted in three steps, for example, 20 Hz, 30 Hz, or 50 Hz. The amplitude can be adjusted by changing the rotational direction of the rotating shaft 104 as described above, and the frequency can be adjusted by changing the rotation speed of the rotating shaft 104.

The vibrating plate 20 has a rubber mat 21 on the upper surface side on which the user M (see FIG. 6) rests his or her feet. The rubber mat 21 is provided with marks (lines in this embodiment) at predetermined positions (the positions where the user M places his/her feet). The marks made on the rubber mat 21 are made symmetrically with respect to the center of gravity of the vibration plate 20. A fixing plate 102 (see FIG. 4) of the vibration generating unit 100 is fixed near the center on the lower surface side of the vibration plate 20. Therefore, the vibrations generated by the vibration generating unit 100 are transmitted to the vibration plate 20. This causes the vibration plate 20 to vibrate. Further, as shown in FIGS. 2(a) and 2(b), the vibrating plate 20 is supported by an elastic member 30.

As shown in FIGS. 3A and 3B, four elastic members 30 are disposed at each of the four chamfered portions of the support base 10. As shown in FIGS. The elastic members 30 are arranged along the chamfering direction of each chamfered portion.

As shown in FIG. 2(a), the elastic member 30 is a rubber member formed in a hexagonal ring shape in this embodiment. The elastic member 30 is disposed between the support base 10 and the vibrating plate 20, and supports the vibrating plate 20 from the bottom side with its upper surface. Further, the lower surface of the elastic member 30 is supported on the upper surface side of the support base 10. Thereby, the elastic member 30 supports the vibrating plate 20 from below and urges the vibrating plate 20 upward. The four elastic members 30 are arranged symmetrically with respect to the center (center of gravity) of the vibrating plate 20, respectively. That is, the vibrating plate 20 is equally supported by the four elastic members 30 and is maintained in a nearly horizontal state. Although details will be described later, the elastic member 30 has an elastic force in the vertical direction according to a predetermined elastic coefficient, and is elastically deformed with a predetermined elastic force when a load is applied to the vibration plate 20. It is possible to do so.

In this embodiment, the displacement meter 40 uses a non-contact type displacement meter (for example, a laser displacement meter). As shown in FIGS. 2 and 3(b), the displacement meter 40 is arranged in an area between the support base 10 and the vibration plate 20, avoiding the area where the elastic member 30 and the vibration generation unit 100 are arranged. There is. Specifically, the displacement meter 40 is attached to the lower cover 3b below the center of gravity of the vibration plate 20 via a bracket (not shown). Further, as shown in FIGS. 2(a) and 2(b), the opening 12 of the support base 10 is located above the displacement meter 40 so as not to interfere with the measurement by the displacement meter 40. Further, a reflecting member 41 is provided above the opening 12 so as to face the displacement meter 40 . The reflecting member 41 is fixed to the bottom plate 108 of the vibration generating unit 100. The reflecting member 41 can reflect the laser beam irradiated from the displacement meter 40. The displacement meter 40 can measure the distance to the reflecting member 41 from the light reflected by the reflecting member 41. Details of the measurement of the displacement amount L by the displacement meter 40 will be described later.

Here, the center of gravity of the vibrating plate 20 is located at a position that coincides with the center in the horizontal direction of the area where the four elastic members 30 are arranged. Therefore, the displacement meter 40 can detect displacement at a position that is less affected by vibration. That is, since the center of gravity of the vibrating plate 20 does not swing much in directions other than the vertical direction when the vibrating plate 20 vibrates, the amount of displacement L in the vertical direction can be detected with high accuracy. Moreover, if a non-contact displacement meter is used as the displacement meter 40 as described above, the degree of freedom in the position where the displacement meter 40 is arranged can be increased. Note that the displacement meter 40 may be a contact type as well as a non-contact type depending on the layout.

As shown in FIGS. 2A and 5, the control unit 50 is provided on the rear side of the lower cover 3b (on the lower side of the support column 4). The control unit 50 is configured by, for example, a computer, and includes a calculation unit 51, a storage unit 52, and the like, as shown in FIG. Further, the control unit 50 is connected to a displacement meter 40, a display device 60, an input unit 61, a motor driver 113, and the like. The control unit 50 can control the entire operation of the vibration training device 1. The control unit 50 can generate vibrations according to the conditions set by the input unit 61.

The motor 101 is connected to the motor driver 113 . The motor driver 113 can perform drive control of the motor 101 according to commands from the control unit 50.

The calculation unit 51 can perform calculation processing on the amount of displacement measured by the displacement meter 40. Specifically, the calculation unit 51 can calculate the load applied to the vibration plate 20 based on the amount of vertical displacement of the vibration plate 20 measured by the displacement meter 40. Note that details of the calculation of the load by the calculation unit 51 will be described later. The calculation unit 51 is capable of performing various calculation processes and controls in the vibration training device 1 in addition to calculating the load.

The storage unit 52 is composed of a storage medium such as a flash memory. The storage unit 52 can store various information (gender, age, weight, etc.), training conditions, etc. of the user M (patient M). Further, the storage unit 52 can appropriately call up stored information and display it on the display device 60 or set training conditions on the input unit 61.

The above is the configuration of the vibration training device 1 according to the present invention.Next, details of the vibration application method using the vibration training device 1 and the calculation of the load in the calculation unit 51 will be described.

In this embodiment, as shown in FIG. 6, a case will be described in which the user M places only his feet (body part to which vibrations are to be applied) on the vibration plate 20. First, before vibration is applied by the vibration training device 1, vibration conditions for the vibration are set in advance via the operation panel 6.

FIG. 7 is a chart showing vertical displacement of the vibrating plate 20 by the displacement meter 40. As shown in FIG. The height of the vibration plate 20 is at a first position P1 (not shown) before the user M puts his or her feet on it. That is, the displacement meter 40 indicates a displacement amount of 0 (zero). Further, the height at this time (the height in the non-vibration state) is set as the first position P1 by the control unit 50 (calculation unit 51) (first position setting step). In other words, the no-load state of the vibration plate 20 is set as the first position P1. Note that the first position P1 may be set manually or automatically.

Next, in a state before vibration is applied to the vibration plate 20 (also referred to as a non-vibration state), the user M sits on a separately prepared chair 7 and positions the vibration plate 20 at a predetermined position (for example, at a mark). (see Figure 6). That is, in this embodiment, the entire weight of the user M is not applied to the vibrating plate 20, but only the weight of the user's M feet is applied. Further, the user M holds the handle 5 at a predetermined position so as to take a predetermined posture (see FIG. 6). At this time, as shown in FIG. 7, as a load is applied to the vibrating plate 20, the height of the vibrating plate 20 is measured as a second position P2 by the displacement meter 40 (second position measurement step). Specifically, the displacement meter 40 measures the displacement amount L1 (also referred to as the initial displacement amount L1) from the first position P1 to the second position P2.

Here, the load W can be calculated based on the elastic modulus K of the elastic member 30. The elastic modulus K can be determined in advance from the relationship between the amount of contraction of the elastic member 30 (measured with a compression meter, etc.) according to the load. Note that when a spring is used as the elastic member 30, a spring coefficient may be used. For example, when a spring that changes linearly is used as the elastic member 30, the load W can be calculated by the following (Formula 1). When using the elastic member 30 that does not change linearly, (Formula 1) may be modified according to the elastic deformation of the elastic member 30.

Load W = 4 (number of springs) x K (spring coefficient) x L (displacement) (Formula 1)

Therefore, when the above-mentioned initial displacement amount L1 is measured, the calculation unit 51 calculates the reference load W1 (load amount W1) based on the initial displacement amount L1 (reference load calculation step). Here, the reference load W1 can be calculated using (Formula 2) based on (Formula 1).

Standard load W1 = 4 (number of springs) x K (spring coefficient) x L1 (initial displacement amount) (Formula 2)

As described above, in the vibration training device 1 and the vibration application method of the present invention, the load (reference load) applied to the vibration plate by the user M in a non-vibration state can be measured by the reference load calculation step. As a result, the vibration training device 1 and the vibration application method of the present invention can measure the load W (for example, the weight of the user M or the weight of a part of the body) even in a non-vibration state that could not be measured conventionally. be able to. Therefore, since there is no need to measure the weight (apparent weight) of the user M in advance, there is no need for, for example, an elderly person, a person in need of care, etc. to take the trouble to separately weigh themselves on a scale. This can be expected to reduce the burden on the user and the caregiver. Further, since it is difficult for many users such as frail elderly people to increase the load, changes in the amount of load itself are useful in determining the effect of vibration training. By objectively observing the weight, it is possible to establish a training protocol for each user, and it may also lead to establishing evidence for developing effective rehabilitation methods.

In the reference load calculation step, when the reference load W1 is calculated, the user M applies vibration to the vibration plate 20 with his or her feet placed on the vibration plate 20, thereby bringing it into a vibration state (vibration generation step). In the vibration generation step, the control unit 50 performs control to generate vibration according to predetermined vibration conditions. Note that the application of vibration can be started by the user M, a physical therapist, a caregiver, or the like operating an operation button (input unit 61) displayed on the display device 60.

In the vibration generation step, as shown in FIG. 7, vibration is applied at a predetermined frequency (50 Hz in this embodiment). In the vibration generation step, the height of the vibration plate 20 is displaced with a predetermined amplitude around the second position P2 (a state where a reference load is applied). That is, the height of the vibrating plate 20 is displaced in one period of 0.02 seconds. In this embodiment, the sampling interval of the displacement meter 40 is, for example, 0.002 seconds. Therefore, sampling is performed 10 times per cycle, and data related to the displacement amount L (displacement from the first position P1) is sampled. In this embodiment, it is assumed that the displacement (height H) from the first position P1 is sequentially displaced in the order of a, b, c, d, e, f, g, h, i, and j for each sampling.

The calculation unit 51 calculates the displacement amount L by performing a moving average of the height H detected by sampling at a predetermined time based on the following (Equation 3).

Displacement amount L=(H1+H2+...Hn)/n...(Formula 3)

Note that the specific displacement amount L in this embodiment can be calculated based on the following (Formula 4).

Displacement amount L=(a+b+c+d+e+f+g+h+i+j)/10...(Formula 4)

The calculation unit 51 calculates the load W based on the displacement amount L in the vibration state (vibration state load calculation step). That is, the load W applied to the vibrating plate 20 by the foot of the user M (load W excluding the influence of fluctuations due to amplitude) is calculated. In this way, in this embodiment, the displacement amount L is calculated by the moving average method. Therefore, the load W can be calculated with high accuracy without increasing the number of samplings more than necessary. Thereby, the vibration training device 1 and the vibration application method of the present invention can reduce the load on the calculation unit 51. Further, the vibration training device 1 and the vibration application method of the present invention can apply vibrations to the user M while the reference load W1 is applied to the vibration plate 20.

Either or both of the load W measured in the non-vibrating state and the vibrating state and the load change with respect to the reference load W1 are displayed directly or indirectly on the display device 60 (display step). Here, what is directly displayed on the display device 60 is exemplified by a numerical representation of the actual load W or the reference load W1. Further, examples of what is indirectly displayed on the display device 60 include what is visually displayed as a graph and what is displayed as an indicator of a positive or negative change with respect to the reference load W1.

In this way, the display device 60 can display either or both of the load W and the displacement L directly or indirectly. Therefore, the vibration training device 1 and the vibration application method of the present invention visually provide the user M (for example, an elderly person or a person in need of care) with a target value (guideline) when applying vibration. I can do it. Therefore, the vibration training device 1 and the vibration application method of the present invention can apply vibration to the user M based on the accurate load W and displacement amount L, and have an appropriate training effect (muscle stimulation). effect) can be obtained. Further, the vibration training device 1 and the vibration application method of the present invention can improve the convenience of an assistant (for example, a physical therapist or a trainer) who assists the training of the user M, for example.

In addition, the vibration training device 1 of the present invention uses the displacement meter 40 to detect the amount of vertical displacement L of the vibration plate 20, with the height H when the vibration plate 20 is in a non-vibration state being the first position P1. It is possible to do so. That is, the vibration training device 1 can detect the vertical displacement amount L of the vibration plate 20 in a non-vibration state. Therefore, the vibration training device 1 can calculate the load W applied to the vibration plate 20 based on the detected displacement L. Thereby, the vibration training device 1 can measure the load W (for example, the weight of the user M or the weight of a part of the body) even in a non-vibration state, which could not be measured conventionally. Therefore, since there is no need to measure the weight (apparent weight) of the user M in advance, there is no need for, for example, an elderly person, a person in need of care, etc. to take the trouble to separately weigh themselves on a scale. Further, the effect of reducing the burden on the user M and the burden on the caregiver can be expected.

Moreover, since the vibration training device 1 of the present invention can calculate the load applied to the vibration plate 20 based on the amount of displacement L from the first position P1, even when vibration is applied to the vibration plate 20, The load W applied to the vibrating plate 20 can be calculated based on the position P1. Furthermore, the vibration training device 1 can calculate the load W without using a lookup table (comparison table). Therefore, the vibration training device 1 can improve the measurement accuracy of the load W.

As described above, in the vibration training device 1 of the present invention, the calculation unit 51 sets the state where the user M puts his or her feet on the vibration plate 20 in a non-vibration state as the second position P2, and moves from the first position P1 to the second position P2. The reference load W1 can be calculated based on the amount of displacement L1 to the second position P2, and the display device 60 can directly or indirectly display the load change with respect to the reference load W1 when the vibration plate 20 is in a non-vibrating state and a vibrating state. It is said that it can be displayed.

Here, the reference load W1 is the weight of the user M when the user M applies the entire body weight, and when the user M applies the load W with only the feet placed on the vibration plate 20, the reference load W1 is the weight of the user M. This becomes a load (load from feet). Therefore, when the vibration training device 1 of the present invention changes the vibration plate 20 from a non-vibration state to a vibration state, the display device displays the load change in the vibration state based on the reference load W1 (load amount) in the non-vibration state. 60 can be displayed. As a result, the vibration training device 1 of the present invention can appropriately apply vibrations to the user M based on accurate load changes, and can provide appropriate training effects (muscle stimulation effects, balance improvement effects). , blood flow improvement effect, etc.).

Next, methods for implementing training according to purpose using the vibration training device 1 of the present invention will be described below.

≪About training methods≫
The main goals of training include improving muscle strength, improving the sense of balance, dilating blood vessels, and improving flexibility. Therefore, the vibration training device 1 is provided with modes (menus) for different purposes. For example, modes aimed at improving muscle strength include a "gentle muscle training mode" and a "hard muscle training mode." When it comes to improving muscle strength, leaning forward and placing your weight firmly on the soles of your feet will be more effective.

As shown in FIG. 10(c1), first, the user M takes a seat on the chair 7 whose height has been lowered, and assumes a squat position. Further, the user M places his or her feet on a predetermined position on the vibrating plate 20 with the feet at a normal width. In this state, vibration is applied to the vibration plate 20. Note that the vibration conditions in the "balance improvement mode" are a frequency of 40 Hz and an amplitude of 2 mm. Further, the training conditions are such that one set consists of applying vibration according to the above vibration conditions for 30 seconds and then taking a rest for 60 seconds, and this is performed three times (times). It should be noted that during training, the training is performed while being checked using the indicator shown on the display device 60.

Subsequently, as shown in FIG. 10(c2), the height of the chair 7 is lowered so that the user M is in a deep squat state. Training is performed with one foot placed on the vibrating plate 20 under the same training conditions as in FIG. 10(c1).

Subsequently, as shown in FIG. 10(c3), the height of the chair 7 is raised so that the user M is in a light squat state with his eyes closed. In this state, training is performed under the same training conditions as those shown in FIG. 10(c1). In this way, by using the vibration training device 1 of the present invention, it is possible to perform accurate balance improvement training while visually checking the load condition. The details of the "balance improvement mode" have been described above, and the details of the "stretch mode" will be explained below with reference to FIG. 10.

≪Stretch mode≫
The "stretch mode" is said to perform training aimed at improving the flexibility of the body. As shown in FIG. 11(d1), first, the auxiliary plate 8 is provided in an inclined state at the front end portion of the vibrating plate 20 so that the calf of the user M can stretch. The user M sits on the chair 7 so that the soles of his feet are in contact with the auxiliary board 8.

Next, as shown in FIG. 11(d2), by removing the auxiliary plate 8, the calf of the user M is stretched and the heel is placed on the vibrating plate 20. In this state, vibration is applied to the vibration plate 20. Note that the vibration conditions in the "stretch mode" are a frequency of 30 Hz and an amplitude of 2 mm. In addition, the training conditions were to apply vibration according to the above vibration conditions for 10 seconds while user M's calves were stretched, and then apply vibration according to the above vibration conditions for 5 seconds while in a stretched state, which was 4 sets. It is said that it will be held (times). That is, the total vibration application time for one set of training is 1 minute. It should be noted that during training, the training is performed while being checked using the indicator shown on the display device 60. In addition, training is performed with support from a physical therapist or the like as appropriate.

Subsequently, as shown in FIG. 11(d3), the user M's legs are bent so that the user's legs are placed on the front side of the vibration plate 20 (stretched state). In this state, vibration is performed for 5 seconds under the above vibration conditions.

Here, the user M is seated on the chair 7 in a relaxed state with legs stretched out. As a result, the user M's extended legs are placed on the vibrating plate 20. That is, the portion of the user M from the calf to the heel is in contact with the vibration plate 20. In this state, vibration is applied under the same vibration conditions as in FIG. 12(d1). Here, the training conditions are such that one set consists of applying vibration under the above-mentioned vibration conditions for 60 seconds, followed by a 10 second break, and this is performed for three sets (times). In this way, by using the vibration training device 1 of the present invention, it is possible to accurately perform training by improving fatigue and blood flow while visually checking the load condition. The above are the details of the "fatigue blood flow improvement mode".

As described above, the "balance improvement mode", "stretch mode", and "blood flow improvement mode" are performed in the normal posture, not in the forward leaning posture. Therefore, in the normal posture, the weight is not placed on the soles of the feet as much as in the forward leaning posture, so the level of the load meter is lower than in the forward leaning posture. Further, in the vibration training device 1 according to the present invention, when vibration (pressure fluctuation information) is applied from the sole of the foot, it is converted into position information in space, and by continuing this, the detection power in the central nervous system is increased. You can improve your sense of balance. Further, the vibration training device 1 of the present invention has the advantage that it is easy to use not only for training of healthy people but also for patients who require assistance. For example, a caregiver can visually check the indicator in real time while the elderly person or patient is training, thereby encouraging the elderly person or patient to adopt an appropriate posture. Note that the frequency, amplitude, training time, etc. may also be optimized for each purpose of training. Further, the chair 7 may be provided as appropriate, and the chair 7 may be incorporated into the vibration training device 1.

Further, the displacement amount L and the load W can be calculated not only by the moving average method but also by various arithmetic means. Further, in this embodiment, a calculation method that does not use a lookup table (comparison table) is exemplified, but it is also possible to perform calculations using a lookup table. Further, in this embodiment, an example is shown in which the apparent weight is not used by eliminating a separate weight measurement, but it is also possible to perform a separate weight measurement and use the apparent weight. For example, vibrations may be applied to the entire body or a part of the body of the user M, taking into consideration the apparent weight.
