Description

TECHNICAL FIELD The present invention relates to a training method and a training device for improving a person's ability to move using their legs, and more particularly to a training method and a training device for enhancing the muscle strength of the thigh in a well-balanced manner.

When aiming to improve walking ability and running ability, it is essential to increase the strength of the thigh muscles, and walking training on the road is common. A so-called running machine or the like is known as a typical thigh training device. In addition, the inventor of the present invention has developed a wearable walking promoting device that stimulates the skin just above the sacrum with a continuous electric current and appropriately adjusts the walking speed, walking style, stride length, joint angle of the lower limbs, and walking cycle to promote walking efficiently. (For example, see Japanese Patent Application Laid-Open No. 2015-177927). It can be expected that the balance of the foot will also improve dramatically.

JP 2015-177927 A

However, so-called running machines are used in a standing posture, so when running, not only does the load on joints such as the hips and knees, which is several times the body weight, be applied, but also walking training on the road is necessary. When using a wearable walking promoting device such as that described above when using it in a running machine or the like, the walking brought about by the walking promoting device depends on the balance of left and right leg strength, the difference in left and right leg length, and the difference in physical strength during walking. Temporal variations in facilitation effects may be observed. It is thought that such variation in the effect due to individual differences is due to the fact that different loads are applied to both feet in the first place due to the characteristics of each individual.

The present invention has been made by paying attention to such problems, and reduces the burden on joints such as the hips and knees, and increases the muscle strength of the thighs of both the left and right legs in a balanced manner to improve walking ability.

A limited movement is required, and the thigh muscles of both the left and right legs can be effectively strengthened in a well-balanced manner during the pedaling movement. In addition, when pedaling, the movement of one leg is always linked to the movement of the other leg, so the stimulation of the motor center of the spinal cord by electrical stimulation waves balances the movement of the left and right legs. will promote. In addition, when the user pedals the two left and right pedals with both legs, the buttock region is supported by the seat and most of the weight of the human body is supported. There is less burden on joints such as hips and knees due to

Therefore, the reaction force by the other leg can be detected.

The stimulation process is characterized by including an adjustment process for relatively adjusting the outputs of the left and right electrical stimulation waves.

It functions as a backrest.

Further, armrests 24, 24 are fixed to the vertical rod portions 12b, 12b of the left and right side frames 12, 12 by fixing means 25, 25, respectively. Furthermore, as shown in FIG. 2, a grip-operable brake device 26 is fixed via fixing means 27 to the horizontal rod portion 12a of the side frame 12 on the right side in front view. For convenience of explanation, the braking device 26 is shown only in FIG. 2 and is omitted from other drawings.

The shaft member 22 and the pedal cranks 5 , 5 are in a transmission relationship by a transmission device 23 . According to this, by rotating the pedal cranks 5, 5, the driving force of the cranks is transmitted to the shaft member 22, and the driving wheel 20 fixed to the shaft member 22 rotates. The transmission device 23 is a so-called fixed gear without a free wheel, so that the rotation of the pedal cranks 5, 5 is always transmitted to the drive wheel 20 via the shaft member 22 in a state where there is no free position. It's becoming

The pedaling device 2 has the lower seat member 17 and the upper seat member 18 as described above, and the pedals 19 , 19 are provided in front of the lower seat member 17 . Therefore, the reaction force when the user presses the pedals 19, 19 can be received especially by the waist and back supported by the upper sheet member 18, so that the pedaling motion is performed by pushing the legs forward. , the pedals 19, 19 are structured so that the weight is not applied when the pedals are pushed. Therefore, the transmission efficiency of leg force is stabilized, the burden on joints such as the hips and knees is reduced, and the muscular strength of the thigh can be concentrated and strengthened. In addition to the lower seat member 17 supporting the buttocks region, the waist and back are supported by the upper seat member 18, so that the body weight can be distributed over a wide range and the burden is reduced even when used for a long time, which is suitable for training.

Next, the motion promoting device 3 will be described with reference to FIGS. 1 and 4 to 6. FIG. As shown in FIGS. 1 and 4 , the motion promoting device 3 is mainly composed of a control body 30 and an electrode device 31 . As shown in FIG. 4 , the control body 30 includes a power supply unit 33 , which is a battery, a central control unit 34 and an output unit 35 inside a box-shaped exterior member 32 .

The control body 30 further includes a power switch 36, an adjustment dial 37, and a selector switch 38 exposed outside the exterior member 32. The power switch 36 is electrically connected to the power supply 33 and the central control device 34. , the adjustment dial 37 and the switch 38 are electrically connected to the central control unit 34, respectively.

The electrode device 31 is mainly composed of wiring 39 and electrode devices 40A and 40B. The wiring 39 is connected to the output section 35 and is divided into two in the middle of the longitudinal direction, each having connectors 41, 41 at its ends.

Since the electrode device 40A and the electrode device 40B have substantially the same structure, the electrode device 40A will be described below, and the description of the electrode device 40B will be omitted. The electrode device 40A has a sheet shape including a pad portion 40a to be attached to the skin and a wiring portion 40b extending from the pad portion 40a. The wiring portion 40b is constructed by sandwiching a conductive sheet 40d between non-woven fabrics or the like, and a conductive electrode 40c continuous with the conductive sheet 40d of the wiring portion 40b is exposed on the surface of the pad portion 40a. One side of a conductive adhesive member (not shown) is attached so as to cover the electrode 40c, and the other side is attached to the skin. Since the performance of the conductive adhesive member deteriorates due to adhesion of skin secretions, etc., it can be replaced with a new one as needed.

The connector 41 has a structure like a so-called clip, and clamps the end of the wiring portion 40b of the electrode device 40A to fix and electrically connect the wiring 39 and the wiring portion 40b. In this way, the connector 41 can easily switch between the sandwiched state and the released state of the wiring portion 40b.

The central controller 34 is adapted to send electrical stimulation signals to the electrode device 31 from an output 35 having a D/A converter with an output determined by the central controller 34 . The adjustment dial 37 is an operation unit that adjusts the strength of the electrical stimulation output from the output unit 35 by acting on the central control device 34, and the changeover switch 38 acts on the central control device 34 to control the electrical stimulation output from the output unit 35. to a frequency in the range of 0.5 to 3 Hz and a frequency in the range of 20 Hz to 5 kHz.

FIG. 6 shows a state in which the pad portions 40a and 40a of the electrode devices 40A and 40B of the movement promoting device 3 are directly attached to the skin so that the electrodes 40c and 40c are located on both sides of the center line of the user's sacrum. showing. Regardless of gender, the human pelvis generally consists of a substantially inverted triangular sacrum B sandwiched between a pair of left and right ilium (the ilium, pubic bone and ischium are collectively referred to as coccal bones). The electrical stimulation waves output from the output unit 35 and applied to the electrodes 40c, 40c are unipolar negative rectangular waves or bipolar rectangular waves with a pulse width of 1 to 500 μs, and are continuous stimulation or continuous intermittent stimulation.

In addition, the motion promoting device 3 uses, for example, an electrical stimulation frequency within the range of 0.5 to 3 Hz for people with walking disabilities or difficulty in walking, and an electrical stimulation frequency of 20 Hz to 5 kHz for healthy people. It is used by switching the switch 38, and the electric stimulation frequency is adjusted by appropriately operating the adjustment dial 37 according to the user's physique and exercise ability. The output section is then configured to provide a stimulus output of 20-80 volts and up to 100 volts.

An experiment to measure the number of rotations of the pedals 19, 19 per minute when the pedaling device 2 is used for the same subject using the movement promoting device 3 and when not using the movement promoting device. As a result, a result was obtained that the number of revolutions was higher when the motion promoting device 3 was used than when the motion promoting device 3 was not used. According to this experiment, by using the movement promoting device 3, the electric stimulation waves given to the electrodes 40c, 40c are output to both sides of the center of the sacrum B, thereby stimulating the motor center of the spinal cord, and the pedals 19, 19 It was found that the action of rowing the leg, that is, the action of pushing forward after pulling up the leg, can be promoted.

Next, an example of a mode of actually using the training device 1 will be described with reference to FIGS. 7 and 8. FIG. First, the user attaches the pad portions 40a, 40a of the electrode devices 40A, 40B to the skin portions directly above the center of both sides of the sacrum B (see FIG. 6), and attaches the lower sheet member 17 of the pedaling device 2. The buttocks area is placed on the rear side 17a (seat part), and the user sits on the upper seat member 18 with the back resting thereon.

Next, the ends of the wiring portions 40b, 40b of the electrode devices 40A, 40B are clamped by the connectors 41, 41 provided at the ends of the wiring 39 extending from the control main body 30 supported by the pedaling device 2, and the electrodes are The devices 40A and 40B and the control main unit 30 are electrically connected. In this state, the power switch 36 of the control main unit 30 is turned on, and the changeover switch 38 and the adjustment dial 37 are appropriately operated to output an electric stimulation wave from the output unit 35 (stimulation process). With the electrical stimulation wave being output, the subject puts both feet on the two left and right pedals 19, 19, and begins to pedal.

As shown in FIGS. 7 and 8, the pedaling motion is a motion in which one leg is lifted upward and then pushed forward alternately left and right (exercise stroke). During the pedaling motion, the user supports the buttocks area on the rear side 17a (seating portion) of the lower seat member 17, thereby supporting most of the weight of the human body. The legs are required to perform a limited movement only in the forward and backward directions parallel to each other, so that the muscles of the thighs of the left and right legs can be effectively strengthened in a well-balanced manner in the movement of pedaling the pedals 19, 19. - 特許庁

According to this, when the user pedals the two left and right pedals 19, 19 of the pedaling device 2 with both legs, a pair of left and right electrodes 40c, 40c (Fig. 6), the motor center of the spinal cord is stimulated, and the left and right legs are alternately lifted in the action of pedaling the pedals 19, 19 (in FIG. 7, the right leg is lifted upward). , alternately pushing the left and right legs forward (in FIG. 8, the right leg is pushed forward), and by pedaling the pedals 19, 19, the muscular strength of the thighs of the left and right legs can be enhanced. It can be strengthened in a well-balanced manner. In particular, by using the motion promoting device 3, even a user with disabilities in both legs can pedal the pedals 19, 19 with both the left and right legs. It is possible to strengthen the muscle strength of the thighs of both the left and right legs in a well-balanced manner.

Further, as shown in FIG. 9, by supporting the buttock region H on the rear side 17a (seating portion) of the lower seat member 17, pedaling is performed in a state in which most of the weight of the human body is supported. Therefore, the legs extending forward from the buttock region H are required to perform a limited movement only in the front-rear direction in parallel. can be enhanced. In addition, since the reaction force when the pedals 19 and 19 are pushed can be received by the waist and the back supported by the upper seat member 18 in particular, the buttock region H does not move in the front-rear direction, and the upper and lower thighs in particular do not move. Exercise is effectively promoted. Incidentally, H in the figure indicates the region of the buttocks where the load is applied to the rear side 17a (seating portion) of the lower seat member 17 with the left and right tip portions I, I of the sit bones as the center.

Furthermore, since the cranks 5, 5 have a structure in which the relative position in the rotational direction does not change, in the motion of pedaling the pedals 19, 19, the pedal movement by one leg is always linked to the pedal movement by the other leg. Become. In other words, when the right leg pushes forward, the left leg pushes backward, and together with these linked movements, electrical stimulation waves are applied to the motor center of the spinal cord, resulting in a training effect. improves.

FIG. 9(a) shows the pedal 19 being pushed forward with the right leg. It abuts on the extending front side 17b (extended seat portion) alternately on the left and right sides. FIG. 9(b) shows a state in which the pedal 19 is pushed forward with the right leg, and the rear side T2 of the thigh is in contact with the front side 17b. Therefore, the back side 1 of the thigh of one leg moved in the direction of extending the leg in the pedaling motion abuts against the front side 17b, thereby restricting the downward movement of the knee. can be suppressed, and the motions of the left and right legs can be exercised in a well-balanced manner. In addition, one leg can be temporarily rested, and the exercise burden on the training user can be reduced.

Further, as shown in FIGS. 7 and 8, when the user is seated, the position where the lower sheet member 17 and the upper sheet member 18 of the pedaling device 2 intersect and the portion where the user's sacrum B is located are slightly different. A space S is formed by separating them. According to this, since the pad portions 40a, 40a of the movement promoting device 3 are adhered to the skin portions directly above on both sides of the center of the sacrum B, the pad portions 40a, 40a are arranged in the space S, so that the pad portions 40a can be adjusted during training. , 40a do not come into contact with the lower sheet member 17 or the upper sheet member 18 through clothes and come off, and the pad parts 40a, 40a do not feel uncomfortable due to being pressed against the body, allowing the user to concentrate on training. can be done.

In addition, as described above, the pedaling device 2 has the driving wheels 20 capable of transmitting the driving force of the pedals 19, 19, and can run, so that the user can feel a sense of speed during training without getting bored. can be used for a long time.

In addition, since the wiring 39 extending from the control body 30 of the movement promoting device 3 and the electrode devices 40A and 40B can be electrically connected using connectors 41 and 41 as detachable engaging means, While seated on the pedaling device 2, the user can easily connect the electrode devices 40A and 40B, which are preliminarily attached to the skin directly above both sides of the center of the sacrum B, to the control body 30.

As shown in FIG. 10, both pedals 19, 19 of the pedaling device 2 are provided with the measured value of the moving load applied to the pedal 19, that is, the detected value of the pressure load of the sole over 360 degrees and the time of load detection. , are attached to detectors 45, 45 for simultaneously detecting . The detection unit 45a is, for example, a strain gauge, the pressure load detection value of the sole is measured by the detection unit 45a, and the measured time is simultaneously measured by the clocks in the detection devices 45, 45. . The pressure load detection value of the sole detected by the detection unit 45a and the time of load detection detected by the clocks in the detection devices 45 and 45 can be taken out through an output terminal 45b. By comparing and verifying the exercise capacity of the left and right legs due to the pedaling motion from the measured values taken out through the output terminal 45b, it is possible to take measures to strengthen both the left and right legs in a balanced manner.

A computer connected to the output terminal 45b via a cable or the like graphs the measured values of the moving load detected by the detection device 45 (the detected pressure load on the sole and the time of load detection). In the graph shown in FIG. 11, the movement load when the pedal 19 rotates the crank 5 once is expressed as being distributed circularly around the center point O. are expressed proportionally.

When the crank 5 is rotated once, the movement load of one leg (here, the left crank) is required to be a large forward pushing force when the pedal 19 is positioned near the upper end, that is, a large movement load. As the pedal 19 moves toward the lower end, the required force, that is, the moving load, gradually decreases. Furthermore, the rotation of the pedal cranks 5, 5 is always transmitted to the driving wheel 20 via the shaft member 22 in a state where there is no free position, and the pedal movement by one leg always coincides with the pedal movement of the other leg. Since the movements are linked to each other, when one leg (here the left crank) is positioned near the top, the other leg (here the right crank) is positioned near the bottom. Since the leg on the other side is rotated in the upward direction by the driving force of the pedaling action of the leg on the one side, the movement load is reduced. Therefore, when both the left and right legs perform a pedaling motion in a well-balanced manner, the shape becomes a substantially teardrop shape with a smooth curve as shown in FIG. 11(a).

On the other hand, if the balance between the pedaling motions of the left and right legs is poor, for example, when the other leg pushes the pedal 19 forward, one leg does not move normally because it is out of balance with the other leg. One leg acts as a reaction force that inhibits the rowing motion of the other leg, and the shape of the graph collapses (see FIG. 11(b)). Therefore, this graph was examined, and the degree of approximation to the teardrop-shaped shape of a smooth curve as shown in Fig. 11(a) was used to balance the muscle strength required for thigh walking in the user's leg rowing motion. It is possible to judge whether or not it is close to the ideal rowing motion that is often performed.

The detection devices 45, 45 and the computer may be connected by wireless communication or the like so that the measured value of the moving load detected by the detection devices 45, 45 is instantaneously transmitted to the computer. In the case of such a configuration, data of the moving load measured in the case where both the left and right legs are pedaling in a well-balanced manner set in advance and data of the actually detected moving load measured are combined. When the difference between the two exceeds a predetermined value, the difference is reduced by adjusting the intensity of the electrical stimulation wave based on the pressure load on the soles of the feet. can do. According to this, it is possible to increase the ability of both the left and right legs in a well-balanced manner by adjusting the intensity of the electric stimulation wave while grasping the exercise ability when both the left and right legs perform the pedal exercise at the same time. In addition, the difference between the preset data of the measured value of the moving load when the right and left legs perform the pedaling motion in a well-balanced manner and the data of the actually detected measured value of the moving load is determined in advance. If the value exceeds the value, the computer may, for example, use voice or display to notify the user that the muscle strength required for thigh walking is being exercised in a well-balanced manner, and that the ideal rowing motion is not achieved. good. According to this, the user can immediately recognize that he or she is not performing the ideal rowing motion in order to train the muscle strength necessary for walking the thigh, and can quickly improve the rowing motion. be able to.

Also, in order to relatively adjust the output of the left and right electrical stimulation waves, an acceleration sensor (not shown) is wrapped around the knees or ankles of the training user, and an encoder ( (not shown) may be provided. According to this, it is possible to obtain the acceleration distribution of the left and right legs when the pedal is stepped on. When the difference between the acceleration distribution data when the pedal is stepped on when both legs are pedaling in a well-balanced manner and the acceleration distribution data when the pedal is actually detected exceeds a predetermined value By adjusting the output of the electric stimulation wave and reducing the difference, both the left and right legs can pedal in a well-balanced manner.

Next, a training device according to Example 2 will be described with reference to FIG. It should be noted that the description of the configuration that is the same as that of the above-described embodiment and overlaps will be omitted.
