Description

The present invention relates to a rehabilitation device.
In particular, the present invention enables an effective rehabilitation (function recovery training) to be performed on a hemiplegic symptom person who has left the hemiplegia after having fallen due to cerebrovascular disorders such as cerebral infarction, cerebral thrombus, and subarachnoid hemorrhage. As described above, various ideas have been made.

When a cerebrovascular disorder develops, the patient is admitted to a hospital and undergoes surgical treatment (surgery) or medical treatment using drugs.
Even if such a surgical treatment or medical treatment is performed and the soft tissue such as muscles and ligaments are removed from the state of acute symptoms that hurt, the functional tissue in the brain engaged in physical exercise is damaged. It is often seen. When such damage to the functional tissue in the brain occurs, paralysis occurs on either the left or right side (one side) of the body, and it becomes impossible to move half of the body, that is, hemiplegia (half body attachment). .
In this case, the part where hemiplegia occurs, the degree of hemiplegia, and the like vary depending on the position and degree of damage occurring in the brain, and the degree of hemiplegia and the type of disability vary greatly among individuals.

When hemiplegia occurs as a sequelae of cerebrovascular disorders, rehabilitation is performed to relieve hemiplegia and restore physical function to return to the home or work.
In the case of cerebrovascular disorder, how effective rehabilitation of the optimum type is performed according to each period in the acute phase (within about 1 month from the onset) and recovery phase (about 1 month to 1 year after the onset). Is said to be important in functional recovery.

In the past, it was thought that hemiplegia would not recover after treatment because hemiplegia would not regenerate destroyed brain neurons. For this reason, rehabilitation of persons with hemiplegic symptoms has been aimed at training the lower limbs and upper limbs on the side without paralysis so that they can walk and live daily.
However, recent advances in brain science have revealed that even if part of the brain is damaged, other parts that have escaped damage have the ability to substitute for the role of the damaged part, that is, plasticity, Rehabilitation treatment aimed at overcoming paralysis has also been performed.

For this reason, in rehabilitation, not only can the side without paralysis be trained to enable walking and daily life, but also the side with paralysis can be moved while receiving assistance from others, and the brain can be moved from the paralyzed arm or leg to the brain. It is necessary to promote plasticization of the nervous system (acquisition of cranial nerve substitute ability, nerve regeneration, reorganization) by sending a stimulus to the brain.
When plasticizing the nervous system, in addition to moving the paralyzed arm and leg by a caregiver, etc., the paralyzed person imagines moving the paralyzed arm and leg and moves the body from the brain side. It is said that it is effective to image the movement information command to the side.
In other words, moving the body from the paralyzed side toward the paralyzed side in synchronization with sending a stimulus (motor information command) from the paralyzed side to the brain by forcibly moving the paralyzed arm or leg It is said that the function recovery can be effectively performed by promoting plasticization by interlocking the motion information commands from both directions, which is to imagine that the motion information commands to be commanded are sent.

For this reason, for example, after relieving from the state of acute symptoms that are damaging soft tissues such as muscles and ligaments, rehabilitation is actively performed.
Rehabilitation in the acute phase (within about 1 month from the onset) is centered on “physical therapy”, and rehabilitation in the recovery phase (about 1 month to 1 year after the onset) further adds “occupational therapy”.

  Physical therapy is a therapy designed to improve basic physical ability by performing exercise therapy or manual treatment for the purpose of improving the basic movement ability when a physical function is impaired. This physical therapy begins by slowly turning over and moving the body with the assistance of a physical therapist, following the instructions of a doctor.

Occupational therapy is a so-called therapy that improves applied motion skills, and starts with training to sit on a bed or hold an object. This prevents the limb joint from contracting.
Furthermore, as recovery progresses, we can acquire and improve everyday activities such as changing clothes (changing clothes) and dressing (dressing and shaping), walking training, and eating, toilets, bathing, and washing. Conduct the desired motion training. Such occupational therapy is initially started at the bedside, and then exercise training is performed in actual situations.

When the recovery phase of rehabilitation is complete and functional recovery is achieved to some extent, the patient is discharged from the hospital.
Even after discharge, it is necessary to go to a hospital or rehabilitation facility regularly to perform rehabilitation, and function recovery training is continuously performed according to the menus instructed by doctors and physical therapists. In addition, hemiplegic patients themselves are instructed to move their bodies voluntarily and eagerly.
For this reason, it is important to perform rehabilitation at home, and strong motivation and self-training are required to overcome hemiplegia.

In hospitals and rehabilitation facilities, various rehabilitation devices are provided and rehabilitation using these rehabilitation devices is performed, and home rehabilitation devices are also being developed.
Examples of rehabilitation equipment include parallel walking bars that support a pair of straight parallel bars supported by handrails in a horizontal manner with a support, or a string on a pulley and grip both ends of the string with left and right hands. Legs on the upper and lower limbs exercise trainer that pulls down, the upper limb rotation exercise trainer that grips and rotates the pedal-like object of the bicycle with your left and right hands, the elevating stairs and the slide plate that moves back and forth on the slide rail Various devices have been developed, such as a foot slide exerciser that slides on the foot.

  However, many of the rehabilitation devices are muscle training devices, and few are suitable for symptoms, and are difficult to use. In addition, the equipment itself is expensive, and it has been difficult to continue rehabilitation easily in a general household.

  As mentioned above, rehabilitation is being carried out at hospitals, rehabilitation facilities and homes, but according to the experiences of people who have actually suffered from cerebral infarction, hemiplegia as a sequelae, fighting illness and rehabilitation, the current rehabilitation Then, it was found that there are various problems.

For example, at the time of hospitalization, hemiplegic patients are waiting for most of the time resting on the bed, despite the enthusiasm and willingness to rehabilitate, and the time for rehabilitation is short, The frequency is low.
This is because it is dangerous for a person with hemiplegia who has difficulty in limbs on one side of the body to perform rehabilitation training alone, so it is impossible for a person with hemiplegia to perform rehabilitation training alone, ensuring safety. This is because a physical therapist and a caregiver must accompany the training in order to provide effective training guidance and assistance.
In addition, the size of rehabilitation facilities and the number of rehabilitation devices are limited, and the number of physiotherapists and caregivers is also limited, so that all of the patients with hemiplegia who visit the hospital will be fully rehabilitated. There are also circumstances where it is impossible.

  On the other hand, after discharge, it is necessary to perform rehabilitation at home. For this reason, there are various types of rehabilitation devices for home use, but they are complicated and large-scale, and have few functions to be recovered and are expensive, so they are inconvenient to use at home and have effective function recovery. It was not enough to train.

Furthermore, from the actual experience of the person who became a hemiplegic symptom, the current rehabilitation device does not fully consider the physical / mental state and demands of the person with hemiplegic symptom.
For example, in a parallel bar for walking training, if you walk from one end of the parallel bar to the other end with the parallel bar as a support, the person with hemiplegic symptoms will change direction and this time they will not be able to walk in the opposite direction. However, to change the direction, there is a risk of falling due to loss of balance caused by changing parallel bars or tripping. For this reason, one parallel bar for walking training can only be used by one hemiplegic symptom person, and one person with hemiplegia symptom cannot voluntarily train alone. .

Moreover, in the upper and lower limbs rotation exercise training in which the handle or the pedal is rotated, the training cannot be entered unless the handle or the pedal is grasped.
However, for example, when one arm is paralyzed, the hand on the paralyzed side cannot hold the handle or pedal, and therefore some method (such as tightening with a band) to prevent it from coming off during training. ) To fix the paralyzed hand to the handle or pedal.
For those with hemiplegia, there is no sense of the arm on the paralyzed side, so the position of the arm on the paralyzed side can be confirmed visually, but the position of the arm on the paralyzed side is physically sensed. I can't figure it out. For this reason, the operation itself of bringing the paralyzed arm closer to the handle or the pedal is difficult.
This situation was one of the obstacles to independent training by one person.

Further, in various rehabilitation devices such as an upper / lower limb rotation exercise trainer, there are some devices that move an arm and a leg of a hemiplegic symptom person by an electric mechanism.
In the electric device, there is a certain effect that the blood circulation is improved by moving the arms and legs. However, it is a passive exercise to the last, and it is not an exercise intentionally voluntarily performed by persons with hemiplegic symptoms, but the effect of rehabilitation is weak when viewed from a more positive viewpoint of functional recovery.

In addition, the conventional rotational movement of rehabilitation equipment allows the body to rotate and move along almost the same trajectory, and the body movement movement is subtly adjusted according to the degree of disability and the degree of recovery of rehabilitation. It cannot be changed. For this reason, there is a problem that proper training according to the degree of disability cannot be performed, and a problem that stimulation to the body, brain, muscles and nerves is monotonous.
For example, when rotating the left and right arms, in the conventional device, the rotation phase angle difference between the right arm and the left arm is fixed at 180 degrees, and the rotation phase angle difference is adjusted to the paralysis state of the person with hemiplegia. The change could not be adjusted.
On the other hand, in the early stage of rehabilitation, since the paralyzed arm is difficult to move, the crank direction (phase difference θ = 0 between the left and right arms) is easy to operate. It is possible to rotate even if there is a difference in phase (0 <θ <180 °), and in the latter stage of rehabilitation, it is easy to rotate even if the phase difference between the cranks is around 180 ° (θ = 180 °). In other words, current devices have specifications for the late stage of rehabilitation from the beginning, and there are differences depending on the symptoms, but this is not a preferable method.

Furthermore, the idea of voluntarily training the body on the side without paralysis (healthy side) and the body on the paralysis side did not exist in conventional rehabilitation equipment. In other words, the power and movements of the healthy body are transmitted to the paralyzed body, and the paralyzed body is voluntarily and actively recovered, thereby plasticizing the nervous system (acquiring the ability to substitute for cranial nerves, There was no rehabilitation device that actively promoted nerve regeneration and reorganization.
In addition, most of the conventional rehabilitation devices have a single function, but this makes it easy to go to training and determines the muscles to be used.

The present invention eliminates the problems of the conventional rehabilitation device, operates the rehabilitation device with the healthy body, transmits power between the upper and lower limbs via the power transmission mechanism, and maintains the paralyzed body healthy. An object of the present invention is to provide a rehabilitation device capable of performing effective rehabilitation by moving with a side force and actively recovering the function of the paralyzed body.
That is, the rehabilitation device is moved with the force of the healthy side, and the paralyzed side is moved along with this, and the same kind of movement is performed after the exercise. After stimulating the brain by exercise, the paralyzed side is moved while recalling the stimulus, and the plasticization of the memory of the brain is further promoted.
For this reason, by combining functions necessary for rehabilitation with a rehabilitation device, it is possible to shift to related areas or other functions in a short time, and therefore, the plasticization of the brain can be made more effective, and also as a device The purpose is to provide a compact rehabilitation device.

  Hereinafter, the form for implementing this invention is demonstrated in detail based on the Example used for the patient with which the left side of the body was paralyzed.

1 and 2 show a composite rehabilitation device 10 according to an embodiment of the present invention.
The composite rehabilitation device 10 is a composite device in which a rehabilitation device 100 for continuous walking and a rehabilitation device 200 for rotary motion are combined.

In the rehabilitation device 100 for continuous walking, a front edge bar 101, a right edge bar 102, and a left edge bar 103 are joined and connected to form a U-shaped bottom structure.
In this way, the bottom plate 104 is fixed to the U-shaped bottom structure formed by connecting the front edge rod 101, the right edge rod 102, and the left edge rod 103.

The column 105a is joined to a position slightly forward (front edge bar 101 side) of the right edge bar 102 from the center position, and extends vertically upward. The support column 105b is joined to a position on the rear edge side of the right edge bar 102, and extends vertically upward.
The support column 105 c is joined to a position slightly forward (front edge bar 101 side) of the left edge bar 103 from the center position, and extends vertically upward. The column 105d is joined to a position on the rear edge side of the left edge rod 103, and extends vertically upward.

The loop-shaped handrail bar 106 is configured by connecting a U-shaped handrail bar 106a and a U-shaped handrail bar 106b.
Among these, the U-shaped handrail bar 106a is connected to the tops of the four columns 105a, 105b, 105c, and 105d and supported horizontally.

One end (right end) of the U-shaped handrail bar 106b is rotatably connected to one end (right end) of the handrail bar 106a, and the other end (left end) of the handrail bar 106b is the other handrail bar 106a. It is detachably connected to the end (left end).
Therefore, as shown in FIG. 1, when the other end (left end) of the handrail bar 106b is connected to the other end (left end) of the handrail bar 106a, the handrail bars 106a and 106b are connected in a loop and horizontally. A handrail rod 106 is formed.
On the other hand, as shown in FIG. 2, the other end (left end) of the handrail bar 106b is opened from the other end (left end) of the handrail bar 106a, and the handrail bar 106b is rotated around its one end (right end). Then, a part of the looped handrail bar 106 is opened. In this open state, a human can enter and exit between the internal space surrounded by the loop-shaped handrail rod 106 and the external space on the outer peripheral side of the loop-shaped handrail rod 106.

As shown in FIG. 2, a person can enter and exit the looped handrail bar 106 by rotating and closing the handrail bar 106b, or by removing a part of the handrail bar 106a. is there.
That is, as shown in FIG. 1, a handrail opening / closing member 106c, which is a part of the right edge side or the left edge side of the handrail bar 106a (hereinafter, described on the left edge side), is cut out, and a slide member is placed on the left end of the handrail opening / closing member 106c. 108a is provided, and a hinge member 108b is provided at the right end.
With such a configuration, when the slide member 108a is slid to the right, the stump between the handrail bar 106a and the handrail opening / closing member 106c is exposed, so the handrail opening / closing member 106c is moved downward from the hinge member 108b. When bent, the looped handrail bar 106 is in an open state.
Next, in order to change from the open state to the closed state, the handrail opening / closing member 106c hanging downward is turned upward with the hinge member 108b as the center of rotation to be in a horizontal state, and the slide member 108a is slid to the left to move the handrail. The opening / closing member 106c and the handrail member 106a are connected.

  When the loop-shaped handrail rod 106 needs further strength, it is desirable that the connecting rod 107 is arranged from the right end to the left end of the handrail rod 106a.

  The rehabilitation device 200 for rotational movement is arranged so as to be located inside the looped handrail rod 106 of the rehabilitation device 100 for continuous walking.

The main body column (main body support portion) 201 of the rehabilitation device 200 for rotational motion has its lower end connected and fixed to a substantially central portion of the front edge bar 101 and its upper portion connected to the handrail bar 106a via the support bar 202.・ It is fixed.
If one support bar 202 is weak, although not shown in the drawing, the rigidity is improved by making it V-shaped with two support bars and connecting and fixing the V-shaped mating part to the main body column 201. You may plan.
In this way, the main body column 201 is fixed to the front edge bar 101 and the handrail bar 106a, and is erected in an inclined state as a whole.

A rotating shaft holder 210 is fixed to the upper part of the main body column 201. The rotary shaft holder 210 is formed by bending a rectangular sheet metal into a quadrangular cylindrical shape, and rotatably supports the rotary shaft 211. Specifically, the rotating shaft 211 is rotatably supported by the rotating shaft holder 210 using a rolling bearing or a plain bearing.
The rotary shaft holder 210 is not limited in shape and configuration as long as it has the above function.

  A pulley 212 is fixed to a central position of the rotating shaft 211, that is, a portion of the rotating shaft 211 located in the internal space of the rotating shaft holder 210. Therefore, the rotating shaft 211 and the pulley 212 rotate together.

A proximal end portion of a hand crank 213a is detachably attached to the right end of the rotating shaft 211, and a first hand shaft 214a substantially parallel to the rotating shaft 211 is attached to the distal end portion of the crank 213a. Is fixed and installed. A cylindrical handle 215a that can be easily grasped with a healthy hand is rotatably and detachably attached to the first hand shaft 214a.
A proximal end portion of a hand crank 213b is detachably attached to the left end of the rotating shaft 211, and a second hand shaft 214b substantially parallel to the rotating shaft 211 is attached to the distal end portion of the crank 213b. Is fixed and installed. The second hand shaft 214b is assembled with a cylindrical handle 215b that can be easily gripped by a healthy hand, and a forearm holder 300, which will be described later, which is a means for supporting a paralyzed forearm. It is like that.

In this way, the rotary shaft holder 210, the rotary shaft 211, the pulley 212, the cranks 213a and 213b, the hand shafts 214a and 214b, and the handles 215a and 215b constitute the arm rehabilitation device α.
As shown in FIG. 1, handles 215a and 215b may be assembled to the hand shafts 214a and 214b fixed and installed at the distal ends of the cranks 213a and 213b, respectively. Depending on a person's condition and rehabilitation, as shown in FIG. 2, only one of the handles 215a and 215b can be assembled.
2 shows the use state in the initial left hemiplegia (unrecovered state), and a forearm holder 300 described later is attached to the hand shaft 214b.

A rotating shaft holder 220 is fixed to the lower part of the main body column 201. The rotating shaft holder 220 is formed by bending a rectangular sheet metal into a quadrangular cylindrical shape, and supports the rotating shaft 221 rotatably. Specifically, the rotating shaft 221 is rotatably supported by the rotating shaft holder 220 using a rolling bearing or a plain bearing.
The rotary shaft holder 220 is not limited in shape and configuration as long as it has the above function.

  A pulley 222 is fixed to a central position of the rotation shaft 221, that is, a portion of the rotation shaft 221 located in the inner space of the rotation shaft holder 220. Therefore, the rotating shaft 221 and the pulley 222 rotate together.

A base end portion of a foot crank 223 a is detachably attached to the right end of the rotation shaft 221, and a first foot shaft 224 a that is substantially parallel to the rotation shaft 221 is attached to the distal end portion of the crank 223 a. Is fixed and installed. A pedal 225a is rotatably and detachably attached to the first foot shaft 224a.
A base end portion of a foot crank 223b is detachably attached to the left end of the rotation shaft 221, and a second foot shaft 224b substantially parallel to the rotation shaft 221 is attached to the distal end portion of the crank 223b. Is fixed and installed. A pedal 225b and a foot holder 400 described later, which is a means for supporting the paralyzed forefoot, are rotatably and detachably assembled to the second foot shaft 224b.

In this way, the rotary shaft holder 220, the rotary shaft 221, the pulley 222, the cranks 223a and 223b, the foot shafts 224a and 224b, and the pedals 225a and 225b constitute the rehabilitation device β for the leg rotation motion.
Both the pedals 225a and 225b may be assembled to the foot shafts 224a and 224b fixed and installed at the distal ends of the cranks 223a and 223b, respectively. Accordingly, only one of the pedals 225a and 225b can be assembled.

The toothed belt 230 is stretched between the pulley 212 of the rehabilitation device α for the upper arm rotational motion and the pulley 222 of the rehabilitation device β for the lower leg rotational motion. That is, both pulleys 212 and 222 are toothed pulleys that can mesh with the toothed belt 230.
Therefore, when the upper pulley 212 is rotationally driven, this rotational force is transmitted to the lower pulley 222 via the toothed belt 230, and conversely, when the lower pulley 222 is rotationally driven, The rotational force is transmitted to the upper pulley 212 via the toothed belt 230.
Although the above has been described with the toothed belt 230 and the toothed pulleys 212 and 222, a chain and a sprocket may be used, and further, a rotating shaft transmission mechanism using a bevel gear may be used.

Here, the assembled state of the rotating shaft 211 and the cranks 213a and 213b in the rehabilitation device α for rotating the arm will be described with reference to FIGS.
As shown in FIGS. 3A and 4, the main shapes of both end portions of the rotating shaft 211 are polygonal column shapes (in this example, quadrangular column shapes). On the other hand, in the base end portions of the cranks 213a and 213b, fitting holes h whose main shape corresponding to the shape of both end portions of the rotating shaft 211 (in this example, the shape of a quadrangular prism) is a polygon (in this example, a quadrangle). Is formed. That is, the fitting holes h formed in the cranks 213a and 213b can be tightly fitted to both ends of the rotating shaft 211.

For this reason, the crank 213a and the rotating shaft 211 can be assembled | attached by inserting the fitting hole h of the base end part of the crank 213a in the right end part of the rotating shaft 211, and fixing with a volt | bolt etc. Further, the crank 213b and the rotary shaft 211 can be assembled by fitting the fitting hole h at the base end portion of the crank 213b into the left end portion of the rotary shaft 211 and fixing it with a bolt or the like.
In this case, the rotational phase positions of the cranks 213a and 213b with respect to the rotating shaft 211 can be set to arbitrary positions shifted by 90 degrees.

  Therefore, the relative rotational phase angle difference between the left and right cranks 213a and 213b is set to 180 degrees as shown by a solid line in FIG. 4, or +90 degrees, −90 degrees and 0 degrees as shown by a dotted line in FIG. It can also be made. In FIG. 4, the rotational phase position of the right crank 213a is fixed and the rotational phase position of the left crank 213b is shifted, but the rotational phase position of the left crank 213b is fixed and the rotational phase position of the right crank 213a. May be shifted.

Further, by making the shape of the polygonal column at both ends of the rotating shaft 211 and the shape of the fitting hole h of the cranks 213a and 213b more polygonal than the quadrangular shape, relative rotation of the left and right cranks 213a and 213b is achieved. It is also possible to increase the type of phase angle difference.
In order to configure the rotational phase angle difference, the polygon is preferably a regular polygon. In this case, as shown in FIGS. 3B and 3C, the fitting hole h is a regular polygon. However, the shape of the end portion of the rotating shaft 211 may have a part of the cutout as long as the main shape closely fitting with the fitting hole h is a regular polygon. That is, the shape of the end portion of the rotating shaft 211 may be any shape as long as it is a polygonal column shape having a plurality of sides that are closely fitted in the fitting hole h that is a regular polygon.

The assembled state of the rotation shaft 221 and the cranks 223a and 223b in the rehabilitation device β for the leg rotation motion is the same as the assembly state of the rotation shaft 211 and the cranks 213a and 213b in the rehabilitation device α for the arm rotation motion. It is the same.
That is, both end portions of the rotating shaft 221 have a polygonal column shape (in this example, a quadrangular column shape), and the shapes of both end portions of the rotating shaft 221 (in this example) are at the base ends of the cranks 223a and 223b. In this case, a polygonal (quadrangular in this example) fitting hole h corresponding to a quadrangular prism shape is formed. That is, the fitting holes h formed in the cranks 223a and 223b can be tightly fitted to both ends of the rotating shaft 221 (note that the fitting holes formed in the cranks 223a and 223b The symbol h is not shown).

For this reason, the fitting hole h at the base end portion of the crank 223a is fitted into the right end portion of the rotating shaft 221, the fitting hole h at the base end portion of the crank 223b is fitted into the left end portion of the rotating shaft 221, and a bolt or the like is used. By fixing, the cranks 223a and 223b and the rotating shaft 221 can be assembled.
Further, the relative rotational phase angle difference between the left and right cranks 223a and 223b can be set to 180 degrees, +90 degrees, -90 degrees, and 0 degrees.
Further, by making the shape of the polygonal column at both ends of the rotating shaft 221 and the shape of the fitting hole h of the cranks 223a, 223b more polygonal than the quadrangle, relative rotation of the left and right cranks 223a, 223b. It is also possible to increase the type of phase angle difference.
In order to configure the rotational phase angle difference, the polygon is preferably a regular polygon. In this case, the fitting hole h needs to be a regular polygon, but the shape of the end of the rotating shaft 221 is If the main shape is a regular polygon, there may be a part of the cutout. That is, the shape of the end portion of the rotating shaft 221 may be any shape as long as it is a polygonal column shape having a plurality of sides closely fitted in the fitting hole h.

  Next, the forearm holder 300 and the foot holder 400 used when performing rehabilitation using the composite rehabilitation apparatus 10 described above will be described in order.

  FIG. 5A is a side view showing the forearm holder 300, and FIG. 5B is a front view showing the forearm holder 300.

  The forearm holder 300 includes a support plate 301, binder portions 302a and 302b, and a gripping shaft portion 304.

  The support plate 301 is a plate material having a length and a width that supports the hand and forearm of a human (a person with hemiplegia).

  The binder portions 302a and 302b are fixed to the support plate 301 at the center position in the longitudinal direction of the forearm and the position close to the elbow in the longitudinal direction of the forearm, and surround and bind the forearm and the support plate 301 from the outer peripheral side. Thus, the support plate 301 is attached to the forearm. Fixing and releasing of the forearm from the support plate 301 by the binder portions 302a and 302b can be formed by Velcro (registered trademark).

A gripping shaft 304 is provided at the position of the forearm hand in the support plate 301. The gripping shaft portion 304 includes a gripping shaft 304a, a gripping hole 304b formed at the center of the gripping shaft 304a, an L-shaped gripping plate 304c, and an attachment screw 304d.
The gripping shaft 304a is attached to the support plate 301 with an attaching screw 304d. The gripping shaft 304 a is attached to the gripping plate 304 c so as to be substantially parallel to the support plate 301.

  As described above, the gripping shaft portion 304 is provided at the hand position of the support plate 301, and the hand shaft 214a or the hand shaft 214b is rotatably and tightly inserted into the gripping hole 304b of the gripping shaft 304a. By being inserted, it is connected to the rehabilitation device α for arm rotational movement.

  5 (a) and 5 (b) are for left hand paralysis, but for right hand paralysis, the two mounting screws 304d shown in FIG. What is necessary is just to fasten the attachment screw 304d by changing the holding plate 304c 180 degrees to the left and right so as to support the supporting holding shaft 304a from the right side.

  FIG. 6A is a plan view showing a foot holder 400 which is an attachment for a paralyzed foot corresponding to the second pedal, and FIG. 6B is a side view showing the foot holder 400.

  The foot holder 400 includes a foot fixing portion 401, a base 402, and a support pipe (insertion support portion) 403.

The foot fixing portion 401 is composed of a foot fixing portion main body 401a that reaches the sole, heel, and ankle of a human foot, a nose 401b that surrounds the instep, and a heel fixing portion 401c that surrounds the heel.
The base 402 is formed on the bottom surface of the foot fixing portion 401 so as to extend in the foot width direction and the longitudinal direction, and is connected to the foot fixing portion 401 so as to be rotatable by a screw 404 that is a rotation connecting tool. Yes. However, in the rotation, the rotation angle is limited by two stoppers 402a, and the foot fixing portion 401 is limited from being separated from the base 402 by the cover 402b.
Further, a support pipe 403 is provided on the back surface of the base 402 perpendicular to the foot (along the foot width direction). The support pipe 403 includes foot shafts 224a, The 224b can be rotatably and closely fitted, and cannot be removed with a screw or the like (not shown) after the fitting.

  Depending on the situation, instead of the foot holder 400, it is possible to use a normal shoe, a clog or a slipper attached with a pipe or the like functioning as a support pipe along the foot width direction. An inner diameter of the pipe is set so that the foot shafts 224a and 224b at the tips of the cranks 223a and 223b can be rotatably and tightly fitted to the pipe attached to the bottom of a shoe or the like.

  That is, the support pipe 403 can be formed on the bottom of the foot holder (shoes or the like) worn on the foot, into which the foot shafts 224a and 224b at the distal ends of the cranks 223a and 223b can be closely fitted.

  Next, a use operation state when performing rehabilitation using the composite rehabilitation device 10 described above will be described.

When the hemiplegic symptom person is the left arm, for example, a use operation state when performing rehabilitation will be described with reference to FIG.
As shown in FIG. 7, the lifting platform 500 is placed on the bottom plate 104. The lifting platform 500 is a table whose vertical, horizontal, and height dimensions are, for example, 300 mm, 250 mm, and 200 mm, and can be used as a chair by changing the height of the table to change the height. It can be done.
A handle 215a is attached to the right crank 213a of the rehabilitation device α for arm rotation, but the handle 215b is removed from the left crank 213b.

  The forearm holder 300 is attached to the forearm of the left arm of the hemiplegic symptom person P. Next, the hemiplegic symptom person P enters the handrail rod 106 and sits on the lifting platform 500. When entering the handrail bar 106, the handrail bar member 106b is turned open as shown in FIG. 2, or the slide member 108a of FIG. Therefore, when the handrail opening / closing member 106c is folded downward by the hinge member 108b, the handrail opening / closing member 106c extends from the stump of the handrail opening / closing member 106c to the hinge member 108b.

  Then, the hand shaft 214b is closely fitted into the gripping hole 304b provided in the gripping shaft 304a of the forearm holder 300. By doing so, the forearm holder 300 attached to the left forearm can be supported by the left crank 213b.

  The hemiplegic symptom P holds the right handle 215a with the right hand, places the right foot on the right pedal 225a, and places the left foot on the left pedal 225b.

The above is a case where the paralysis of the left foot is mild, but if it is severe, the left foot cannot be stably placed on the left pedal 225b. At this time, it is preferable to use the foot holder 400 of FIG. 6 instead of the pedal 225b.
The foot holder 400 is attached to the support pipe 403 of the base 402 by inserting and fitting the foot shaft 224b. At this time, in order to correct the opening angle of the foot, which varies depending on the person, the foot fixing portion 401 attached to the base 402 at a variable angle is rotated in accordance with the correction amount with the screw 404 serving as the rotation connecting tool as the center of rotation. Further, the paralyzed foot is fixed to the foot fixing portion 401 by the heel fixing portion 401c and the umbilical cord 401b.
Note that the toe side of the foot fixing portion 401 is prevented from being lifted by a cover 402b provided on the base 402, and the turning angle of the foot fixing portion 401 is limited by a stopper pin 402a.

  When the handle 215a is gripped with the right hand and the crank 213a is rotated, this rotational force is transmitted to the left crank 213b, and the left crank 213b rotates. Further, when the cranks 223a and 223b are rotated by pedaling the pedals 225a and 225b, this rotational force is transmitted to the left crank 213b via the toothed belt 230, and the left crank 213b rotates.

For this reason, the forearm holder 300 supported by the left crank 213b and the left forearm to which the forearm holder 300 is attached rotate, and the paralyzed left forearm / upper arm / shoulder moves in conjunction with each other. . The foot holder 400 supported by the left crank 223b also rotates.
In this case, the power of the right arm and both legs or one leg on the healthy side, that is, the power of the body (limbs) that the hemiplegic symptom P itself moved at his own will be transmitted to the paralyzed left arm, Since the paralyzed left arm can rotate, the left arm rotates spontaneously.
Such spontaneous exercise is effective as functional recovery training, and can positively promote the plasticization of the nervous system described above (acquisition of cranial nerve alternative ability, nerve regeneration, reorganization). .

From the state shown in FIG. 7, it is also possible to remove both feet from the pedals 225a and 225b and generate the rotational force only with the right arm, or to release the right arm from the handle 215a and generate the rotational force only with the right foot.
Thus, by changing the movement of the healthy body, the stimulation to the body, nerves and brain changes, and effective function recovery training can be performed.

  Furthermore, as shown in FIG. 4, the rotational phase angle difference between the crank 213a and the crank 213b is changed not only to 180 degrees, but also to +90 degrees, -90 degrees, and 0 degrees. Since the relationship of the rotational phase position of the arm changes, stimulation to the body, nerves and brain changes, and effective function recovery training can be performed.

The above is a case where the left arm is paralyzed, but when the right arm is paralyzed, the handle 215a is removed from the right crank 213a of the rehabilitation device α for rotating the arm. A handle 215b is attached to 213b, and the forearm holder 300 is attached to the right forearm. In order to change the left forearm holder 300 to the right, as described above, after removing the two mounting screws 304d, the gripping plate 304a is supported so that the gripping shaft 304a currently supported from the left side is supported from the right side. What is necessary is just to fasten the attaching screw 304d by changing 304c left and right by 180 °.
Then, the recovery training for the right arm can be performed in the same manner as the recovery training for the left arm described above.

When the hemiplegic symptom person is a left leg, for example, a use operation state when performing rehabilitation will be described with reference to FIG.
As shown in FIG. 8, the lifting platform 500 is placed on the bottom plate 104. In addition, the pedal 225a is attached to the right crank 223a of the rehabilitation device β for leg rotation motion, but the pedal 225b is removed from the left crank 223b.

  The hemiplegic symptom person P enters the handrail 106 and sits on the lifting platform 500. Next, the foot holder 400 is attached to the left leg of the hemiplegic symptom person P.

  Then, the foot shaft 224b at the tip of the crank 223b is closely fitted into the support pipe 403 of the foot holder 400 and locked with a screw or the like (not shown) to prevent it from coming off. By doing so, the foot holder 400 attached to the left foot can be supported by the left crank 223b.

The hemiplegic symptom P holds the right handle 215a with the right hand and places the right foot on the right pedal 225a.
When the crank 223a is rotated by scooping the right pedal 225a, the rotational force is transmitted to the left crank 223b, and the left crank 223b rotates. When the cranks 213a and 213b are rotated by gripping the handles 215a and 215b with the right hand and the left hand as far as possible, this rotational force is transmitted to the left crank 223b via the toothed belt 230, and the left crank 223b rotates.

Therefore, the leg holder 400 supported by the left crank 223b and the left leg to which the leg holder 400 is attached rotate, and the paralyzed left leg / leg rotates.
In this case, the power of the right arm and right leg on the healthy side, that is, the power of the body (limbs) that the hemiplegic symptom P itself moved by his / her own will be transmitted to the paralyzed left leg / leg, Because the left leg and leg that are paralyzed can rotate, the left leg and leg rotate spontaneously.
Such spontaneous exercise is effective as functional recovery training, and can positively promote the plasticization of the nervous system described above (acquisition of cranial nerve alternative ability, nerve regeneration, reorganization). .

In addition, from the state shown in FIG. 8, both hands can be removed from the handles 215a and 215b and the rotational force can be generated only with the right leg, or the right leg can be separated from the pedal 225a and the rotational force can be generated only with the right hand. .
Thus, by changing the movement of the healthy body, the stimulation to the body, nerves and brain changes, and effective function recovery training can be performed.

  Further, by changing the rotational phase angle difference between the crank 223a and the crank 223b to not only 180 degrees but also +90 degrees, -90 degrees, and 0 degrees, the rotational phases of the left and right feet / legs during the rotational movement Because the positional relationship changes, stimulation to the body, nerves and brain changes, and effective function recovery training can be performed.

The above is the case where the left leg is paralyzed, but when the right leg is paralyzed, the pedal 225a is removed from the right crank 223a of the rehabilitation device β for leg rotation motion, A pedal 225b is attached to the left crank 223b, and a foot holder 400 is attached to the right foot.
Then, the recovery training for the right leg can be performed in the same manner as the recovery training for the left leg described above.

  When rehabilitation of persons with hemiplegic symptoms progresses and paralysis is reduced, those with symptoms of motor function decline are used to maintain motor function, and those with decreased physical function ability such as elderly people improve health For example, as shown in FIG. 9, the handle 215a, 215b can be gripped by the left and right hands, and the left and right feet can be placed on the pedals 225a, 225b for rotational movement.

  When performing the up-and-down movement, as shown by a two-dot chain line in FIGS. 7 to 9, the direction of the lifting platform 500 is changed to an optimum height, and the hemiplegic symptom person P is grasped by the handrail rod 106. The base plate 104 and the lifting platform 500 can be moved up and down.

  When standing or sitting, as shown by solid lines in FIGS. 7 to 9, the direction of the lifting platform 500 is changed to set the height to the optimum height as a chair, and the hemiplegic symptom person P moves to the handrail stick 106. While grasping, it is possible to perform a standing / sitting exercise such as sitting on a lifting platform 500 as a chair or standing up.

  When walking, a person with hemiplegia can go out of the handrail bar 106 (outside) and grab on the handrail bar 106 and circulate along the handrail bar 106 to perform a walking motion. In this case, the handrail bar 106 has a loop shape including the rehabilitation device α for arm rotation motion, the rehabilitation device β for leg rotation motion, the lifting platform 500, etc., so the handrail rod 106 is held outside the loop. However, it is possible to continuously perform walking exercise (walking training) without changing the direction of the body.

The composite rehabilitation device 10 described above is a compact component device because the rehabilitation device 100 for continuous walking and the rehabilitation device 200 for rotary motion are combined.
For this reason, it can be used not only in hospitals and rehabilitation facilities but also in homes where installation space is limited.

  Further, by using the forearm holder 300, the arm rotation movement by the rehabilitation equipment α for arm rotation movement can be facilitated, and by using the foot holder 400, the leg rotation movement by the rehabilitation equipment β for leg rotation movement can be facilitated, Since continuous walking training can be performed along the handrail rod 106 in a loop shape, a person with hemiplegic symptoms uses his / her own healthy physical ability without being assisted by an assistant, etc. Rehabilitation can be performed alone (alone).

  In the above embodiment, the composite rehabilitation device 10 is a composite device in which the rehabilitation device 100 for continuous walking and the rehabilitation device 200 for rotational motion are combined. It is also possible to configure each of the rehabilitation devices 200 as a single device.

  In addition, the rehabilitation device 200 for rotary motion includes both the rehabilitation device α for arm rotation motion and the rehabilitation device β for leg rotation motion, but the rehabilitation device α for arm rotation motion and the leg rotation motion. It is also possible to provide only one of the rehabilitation devices β for use.

As described above, according to the apparatus of the present invention (composite rehabilitation device 10), a hemiplegic symptom (patient) cooperates with a healthy arm and a paralyzed arm, cooperates with a healthy leg and a paralyzed leg, and further It was explained in detail that it can be linked with the legs, and functionally, it was shown that it could move up and down, stand and sit, and walk.
In particular, the cooperation between arms and legs is related, but the effects of cooperation with other exercises are uncertain.
However, when this device was used to request operation for a hemiplegic symptom, not only the arm / leg relationship, but also, for example, using a rehabilitation device β for leg rotation exercise, standing / sitting exercise and walking exercise were performed. However, compared with the training in a normal hospital, it was seen that the smoothness was significantly increased in the subsequent walking and cooperation, and the patient himself was also "immediately moving".
However, although it does not become a healthy person at a stretch, the effect is remarkable by shortening the time between work in addition to simultaneously performing multiple different kinds of work.
In other words, if you move to the next task in a short time after finishing the work, in addition to activating the muscles from the previous work, the “plasticity” from the previous work and the next work will be actively linked, and a synergistic effect can be expected in reality. .
In fact, if a break is provided between tasks, many patients maintain their initial state over a long period of time (for example, several months), rather than seeing a synergistic effect.
As stated at the beginning, there are few types of rehabilitation in hospitals and the time between operations is long.
Compared to this, this device can move to the next work in a short time, and the related work of hands (arms) and feet (legs) is linked or linked in a short time. High effects including “plasticity” can be expected.

<Configuration effect of the entire device>
Because we included multiple rehabilitation devices in a loop of handrail bars, we were able to operate hand and foot rehabilitation devices as much as possible.
(1) Can perform voluntary rehabilitation exercises simultaneously or jointly,
(2) It can be moved to different types of rehabilitation equipment in a short time.
Since (1) and (2) described above can be realized, it is possible to expect plasticization of the brain, and it is possible to realize an inexpensive composite rehabilitation device in a small space.
