Training method and training apparatus

The present invention relates to a training method and a training apparatus for improving movement ability using a human foot, and particularly to a training method and a training apparatus used for the same for enhancing the muscle strength of the thigh in a balanced manner.

When aiming to improve walking ability and running ability, strengthening thigh muscle strength is indispensable, and walking training on the road is common. As a typical thigh training apparatus, a so-called running machine or the like is known. In addition, the present inventor stimulates the skin directly above the sacrum with continuous energization, and appropriately adjusts the walking speed, the walking method, the stride, the indirect angle of the lower limb and the walking cycle, and efficiently promotes walking. (See, for example, Japanese Patent Application Laid-Open No. 2015-177927). For example, by using a running machine in a state in which such a walking promotion device is worn, It can be expected that the balance of the foot will be improved dramatically.

Japanese Patent Laying-Open No. 2015-177927

However, since so-called running machines are used in a standing position, when running, they are not only burdened by several times the weight centered on the joints such as the waist and knees, but also walking training on the road. When using a wearable walk-promotion device such as that described above when used for a running machine, etc., the walking provided by the walk-promotion device due to the difference in the left and right leg strength during walking, the difference in left and right leg lengths, and the difference in physical strength Temporary variation may be seen in the promotion effect.

The side frames 12 and 12 are connected at the lower center side by the front crossbar 10 and at the lower rear side by the rear crossbar 11. The side frame 12 is configured by integrally fixing an upper collar member 12A and a lower collar member 12B. The upper collar member 12A includes a lateral collar part 12a extending in the front-rear direction and a rear side end of the lateral collar part 12a. And a handle portion 12c which is bent and extends rearward at the upper end of the vertical tube portion 12b.

An auxiliary wheel 14 is attached to the rear portion of the side frame 12 in the longitudinal direction via an auxiliary wheel support portion 13. In addition, the rear crossbar 11 and the auxiliary wheel support portion 13 are connected by a flange member 15. Although not described in detail in the figure, the auxiliary wheel support portion 13 has a vertically divided structure, and the members of the divided structure are connected to each other so as to be rotatable in the horizontal direction, and when turning by the drive wheel 20 and the driven wheel 21 The auxiliary wheel 14 is oriented in the turning direction described later.

The lower sheet member 17 is fixed to the

lateral flange portions

12a, 12a of the left and right side frames 12, 12 by belt-like fixing means 16, 16,. The upper sheet member 18 is fixed by the fixing means 16, 16,. The lower seat member 17 and the upper seat member 18 constitute a seat portion, the rear side 17a of the lower seat member 17 functions as a seating portion that supports the user's buttocks region, and the upper seat member 18 supports the user's back. It functions as a backrest.

Further,

armrests

24 and 24 are fixed to the

vertical flange portions

12b and 12b of the left and right side frames 12 and 12 by fixing

means

25 and 25, respectively. Further, as shown in FIG. 2, a brake device 26 capable of gripping operation is fixed to the lateral flange portion 12 a of the side frame 12 on the right side when viewed from the front via a fixing means 27. For convenience of explanation, the brake device 26 is shown only in FIG. 2 and is not shown in other drawings.

Further, as shown in FIG. 1, a control main body 30 of an operation promoting device 3 to be described later is detachably fixed to the vertical shaft 12b on the right side when viewed from the front by support means (not shown).

One side in the longitudinal direction of the shaft member 22 is pivotally supported at a substantially central portion of the main frame 4, and the drive wheel 20 is fixed to the other side of the shaft member 22. The shaft member 22 and the leg cranks 5, 5 are in a transmission relationship by the transmission device 23. According to this, the crank driving force is transmitted to the shaft member 22 by rotating the leg cranks 5, 5, and the drive wheel 20 fixed to the shaft member 22 is rotated. The transmission device 23 is a so-called fixed gear that does not include a free wheel, and the rotation of the leg cranks 5 and 5 is always transmitted to the drive wheel 20 via the shaft member 22 in a state where there is no free position. It has become.

The rowing device 2 includes the lower seat member 17 and the upper seat member 18 as described above, and the

pedals

19 and 19 are provided in front of the lower seat member 17. Therefore, since the reaction force when the user presses the

pedals

19 and 19 can be received particularly by the waist and back supported by the upper seat member 18, the pedal rowing operation is performed by the operation of protruding the legs forward. The

pedals

19 and 19 are structured such that no weight is applied when they are pressed. Therefore, the transmission efficiency of leg force is stabilized, the burden on the joints including the waist and knees is small, and the muscle strength of the thigh can be concentrated and strengthened. In addition to the lower seat member 17 that supports the buttocks region, the upper seat member 18 supports the waist and back, so that the weight can be distributed over a wide range, and there is little burden even when used for a long time, which is suitable for training.

Subsequently, the motion promoting device 3 will be described with reference to FIGS. 1 and 4 to 6. As shown in FIGS. 1 and 4, the motion promoting device 3 is mainly configured by a control main body 30 and an electrode device 31. As shown in FIG. 4, the control main body 30 includes a power supply unit 33 that is a battery, a central controller 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 changeover switch 38 that are exposed outside the exterior member 32, and the power switch 36 is electrically connected to the power supply 33 and the central controller 34. The adjustment dial 37 and the changeover switch 38 are electrically connected to the central controller 34, respectively.

The electrode device 31 mainly includes a wiring 39 and

electrode devices

40A and 40B. The wiring 39 is connected to the output unit 35 and is divided into two forks in the longitudinal direction, and is provided with

connectors

41 and 41 at the respective ends.

Hereinafter, since the electrode device 40A and the electrode device 40B have substantially the same structure, the electrode device 40A will be described, and the description of the electrode device 40B will be omitted. The electrode device 40A has a sheet shape including a pad portion 40a attached to the skin and a wiring portion 40b extending from the pad portion 40a. The wiring portion 40b is configured by sandwiching a conductive sheet 40d with a nonwoven fabric 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. In addition, one surface of a conductive adhesive member (not shown) is attached so as to cover the electrode 40c, and the other surface is attached to the skin. Since the performance of the conductive adhesive member deteriorates due to adhesion of skin secretions or the like, it can be appropriately replaced with a new one.

The connector 41 has a so-called clip structure, and fixes and electrically connects the wiring 39 and the wiring part 40b by sandwiching the end of the wiring part 40b of the electrode device 40A. Thus, the connector 41 can easily switch between the pinched state and the released state of the wiring portion 40b.

The central control device 34 can send an electrical stimulation signal to the electrode device 31 from the output unit 35 having a D / A converter with the output determined by the central control device 34. The adjustment dial 37 is an operation unit that works on the central control device 34 and adjusts the strength of the electrical stimulation output from the output unit 35, and the changeover switch 38 works on the central control device 34 and outputs the electrical stimulation output from the output unit 35. Is an operation unit that switches between 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 motion 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. Show. The human pelvis is usually composed of a sacrum B having an approximately inverted triangular shape sandwiched between a pair of left and right iliac bones (referred to as the hipbone including the iliac bone, pubic bone, and ischial bone) regardless of gender. The electrical stimulation wave output from the output unit 35 and applied to the

electrodes

40c and 40c is a unipolar negative rectangular wave or a bipolar rectangular wave having a pulse width of 1 to 500 μsec, and is a continuous stimulation or a continuous intermittent stimulation.

Further, the motion promoting device 3 uses an electrical stimulation frequency within a range of 0.5 to 3 Hz for, for example, a walking handicapped person or a difficult walking person, and uses an electrical stimulation frequency of 20 Hz to 5 kHz for a healthy person or the like. The electrical switch frequency is adjusted by appropriately operating the adjustment dial 37 according to the user's physique and exercise ability by switching the selector switch 38. At this time, the output unit gives a stimulation output of a maximum of 100 volts at 20 to 80 volts.

Experiments for measuring the number of rotations of the

pedals

19 and 19 per minute when using the footing device 2 with and without using the motion promoting device 3 for the same subject. As a result, when the motion promoting device 3 was used, the result was that the number of rotations was higher than when the motion promoting device 3 was not used. According to this experiment, by using the motion accelerating device 3, the electrical stimulation waves given to the

electrodes

40 c and 40 c are output to both sides of the center of the sacrum B, thereby stimulating the movement center of the spinal cord and the

pedals

19 and 19. It has been found that it is possible to promote the action of pushing the legs, that is, the action of pushing the legs forward and then pushing them forward.

Subsequently, an example of a mode when the training apparatus 1 is actually used will be described with reference to FIGS. 7 and 8. First, the user attaches the

pad portions

40a and 40a of the

electrode devices

40A and 40B to the skin portions directly above both sides of the center of the sacrum B (see FIG. 6), and The buttock region is placed on the rear side 17a (sitting portion), and the upper seat member 18 is seated with the back on.

Next, the end portions of the

wiring portions

40b and 40b of the

electrode devices

40A and 40B are sandwiched by the

connectors

41 and 41 provided at the end portions of the wiring 39 extending from the control main body portion 30 supported by the rowing device 2, respectively. The

devices

40A and 40B and the control main body 30 are electrically connected. In this state, the power switch 36 of the control main body 30 is turned on, the changeover switch 38 and the adjustment dial 37 are appropriately operated, and an electrical stimulation wave is output from the output unit 35 (stimulation process). In a state where this electrical stimulation wave is output, both feet are placed on the left and

right pedals

19, 19, and the pedaling operation is started.

As shown in FIG. 7 and FIG. 8, the pedal rowing operation is an operation in which one leg is pulled up and then pushed forward alternately (exercise stroke). At the time of pedaling operation, the user supports the most part of the human body by supporting the buttocks area on the rear side 17a (sitting part) of the lower seat member 17, and thus extends to the front of the buttocks area. A limited movement only in the front-rear direction is required in parallel with both legs that have come out, and the muscles of the thighs on the left and right legs in the movement of pedaling 19, 19 can be effectively enhanced in a balanced manner.

According to this, when a user rubs the left and

right pedals

19 and 19 of the leg rowing device 2 with both legs, a pair of left and

right electrodes

40c and 40c (see FIG. 6), the spinal motion center is stimulated, and the left and right legs in the operation of pedaling 19 and 19 are alternately pulled up (the right leg is lifted upward in FIG. 7). The left and right legs can be pushed forward alternately (the right leg is pushed forward in FIG. 8), and the

pedal

19 and 19 can be operated to increase the strength of the thighs of the left and right legs. The balance can be strengthened. In particular, by using the motion promoting device 3 even when the user has difficulty in both feet, the

pedals

19 and 19 can be rowed with both left and right legs, compared to the case where the user has been walking with rehabilitation, The muscle strength of the thighs of both the left and right legs can be strengthened in a balanced manner.

Further, as shown in FIG. 9, by supporting the buttocks region H on the rear side 17a (sitting portion) of the lower seat member 17, the pedal rowing operation is performed in a state where most of the load on the human body is supported. Therefore, a limited movement in parallel with both legs extending forward in the buttock region H and only in the front-rear direction is required, and the thigh muscles in the left and right legs in the movement of pedaling 19, 19 are balanced and effective. Can be enhanced. In addition, since the reaction force when the

pedals

19 and 19 are pressed can be received by the waist and back supported by the upper seat member 18 in particular, the buttocks region H does not move in the front-rear direction, and particularly the upper and lower parts of the thigh. Exercise will be promoted efficiently. In addition, H in the figure indicates an area of a buttock that applies a load to the rear side 17a (sitting portion) of the lower seat member 17 with the left and right distal ends I, I as the center.

Further, since the

cranks

5 and 5 have a structure in which the relative position in the rotation direction does not change, in the operation of pedaling the

pedals

19 and 19, the pedal movement by one leg is always linked to the pedal movement by the other leg. Become. In other words, the action of pushing forward with the right leg is the action of pushing backward with the left leg, and in conjunction with these linked actions, stimulation of the spinal motor center by electrical stimulation waves is given, and the training effect is effective. improves.

Further, FIG. 9A shows a state in which the pedal 19 is pushed forward by the right leg. At this time, the back side T1 of the thigh of the training user is forward from the rear side 17a of the lower seat member 17. The extended front side 17b (extension seat) is in contact with the left and right alternately. FIG. 9B shows a state where the pedal 19 is pushed forward with the right leg, and the back side T2 of the thigh is in contact with the front side 17b. Therefore, since the back side 1 of the thigh of one leg operated in the direction of extending the leg in the pedaling operation is in contact with the front side 17b, the downward movement of the knee is restricted, so that the twisting of the waist Can be suppressed, and the movements of the left and right legs can be exercised in a balanced manner. Moreover, a break can be given temporarily to one leg, and the exercise burden of the training user can be reduced.

7 and 8, when the user is seated, the position where the lower seat member 17 and the upper seat member 18 of the rowing apparatus 2 cross each other and the portion where the user's sacrum B is located are slightly different. Separated, a space S is formed. According to this, since the

pad portions

40a and 40a of the motion promoting device 3 are attached to the skin portion directly above both sides of the center of the sacrum B, the

pad portions

40a and 40a are disposed in the space S, and therefore are padded during training. , 40a does not peel off due to contact with the lower sheet member 17 or the upper sheet member 18 through clothes, and there is no sense of incongruity due to the

pad portions

40a, 40a being pressed against the body, so that they concentrate on training. Can do.

Further, as described above, the rowing apparatus 2 includes the driving wheels 20 that can transmit the driving force of the

pedals

19 and 19 and can travel, so that the user can feel a sprinting feeling during training and does not get bored. Can be used for a long time.

In addition, the wiring 39 extending from the control main body 30 of the operation promoting device 3 and the

electrode devices

40A and 40B can be electrically connected using

connectors

41 and 41 which are detachable engaging means. The user can easily connect the control main body 30 with the

electrode devices

40A and 40B previously attached to the skin portions directly above the central sides of the sacrum B in a state where the user is seated on the leg row device 2.

As shown in FIG. 10, both

pedals

19, 19 of the rowing device 2 include a measured value of the moving load applied to the pedal 19, that is, a pressure load detection value of the sole over 360 degrees, a load detection time, , Are attached at the same time. The detection unit 45a is, for example, a strain gauge, and the pressure load detection value of the sole is measured by the detection unit 45a, and the measured time is simultaneously measured by a clock in the

detection devices

45 and 45. . Then, the detected pressure pressing load detected by the detecting unit 45a and the load detection time detected by the clock in the detecting

devices

45 and 45 can be taken out via the output terminal 45b. By comparing and verifying the exercise ability of the left and right legs by the pedal rowing operation from the measurement value taken out via the output terminal 45b, it is possible to take measures to enhance both the left and right legs in a well-balanced manner.

The measured value of the moving load detected by the detection device 45 (the pressure load detection value of the sole and the load detection time) is graphed by a computer connected to the output terminal 45b by a cable or the like. In the graph shown in FIG. 11, the movement load when the pedal 19 rotates the crank 5 once is expressed in a circular shape with the center point O as the center, and the distance from the center point O and the value of the movement load are expressed as follows. Are expressed in proportion.

As the movement load of one leg (here, the left crank) when the crank 5 is rotated once, a force that pushes the pedal 19 largely forward in the vicinity of the upper end, that is, a large movement load is obtained. As the pedal 19 moves toward the lower end, the necessary force, that is, the moving load gradually decreases. Further, the rotation of the rowing cranks 5 and 5 is always transmitted to the drive wheel 20 through the shaft member 22 in the state where there is no free position, and the pedal movement by one leg is always the same as the other pedal movement. When the one leg (here, the left crank) is located near the upper end, the other leg (here, the right crank) is located near the lower end. The other leg is rotated in the upper end direction by the driving force generated by the pedaling operation of the one leg, so that the movement load is reduced. Therefore, when the left and right legs perform pedaling operations in a well-balanced manner, a substantially tear-drop shape with a smooth curve as shown in FIG.

On the other hand, if the balance of the pedaling operation of the left and right legs is poor, for example, when one leg pushes the pedal 19 forward and one leg does not balance with the other leg and does not move normally, Acts as a reaction force that hinders the rowing operation of the other leg, and the shape of the graph collapses (see FIG. 11B).

According to this, it is possible to enhance the ability of both the left and right legs in a well-balanced manner by adjusting the intensity of the electrical stimulation wave while grasping the exercise ability when the left and right legs perform the pedal exercise at the same time. In addition, the difference between the measured data of the moving load when the left and right both legs are pedaled in a balanced manner and the measured data of the actually detected moving load is determined in advance. If the value exceeds the value, the computer may be able to give a notification indicating that it is away from the ideal rowing motion that exerts a balance of the muscle strength necessary for walking the thigh, for example, by voice or display. good. According to this, the user can immediately recognize that the ideal rowing motion is not performed in order to train the muscular strength necessary for walking the thigh, and quickly improve the rowing motion. be able to.
