DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for treating or preventing low back pain, and more particularly to a device structure for reducing, eliminating or preventing low back pain by exercising the lower back of a patient.

[0002]

2. Description of the Related Art Patients who come to the hospital for back pain are very common even in daily orthopedic practice.
May account for 30%. However, the content of back pain varies, and the location of pain, the degree of pain, the type of pain, and the like also differ from patient to patient, and some are caused by a number of disease states. These low back pains are caused by various tissues and organs that exist from the lower back to the buttocks of the human body, such as vertebrae, discs,
Diseases such as facet joints, muscles, ligaments, and nerves (tumors, infections,
Deformation, degeneration, metabolism, trauma, inflammation, etc.) alone or in combination.

[0003] Treatments for low back pain can be broadly classified into two types: surgical methods and conservative therapies. Generally, surgery is used when conservative therapy does not improve back pain,
It has the disadvantage of placing a heavy financial, physical and psychological burden on the patient, and there are methods that patients should avoid if possible.
Therefore, it is desirable to provide conservative therapy effectively. The conservative therapy includes resting supine, analgesic administration, injection therapy, traction therapy, hyperthermia, trunk orthosis (corset etc.) therapy, exercise (low back pain gymnastics) therapy and the like.

[0004] Among these treatment methods, exercise therapy is effective in treating or preventing chronic low back pain and low back pain that recurs repeatedly, and is most often used for so-called low back pain. Recently, this exercise therapy has been tried for almost all back pain diseases except for tumors and inflammatory diseases, such as being used for lumbar disc herniation and lumbar spondylolisthesis, etc. after the acute stage.

[0005] Williams' theory is the most general theory of back pain gymnastics. Williams's exercises include pelvic rotation exercise to reduce pelvic anteversion, iliopsoas stretching, abdominal muscle strengthening exercise to reduce lumbar lordosis,
Consisting of lumbar spine stretching. More recently, these movements have included mobilization of vertebral facet joints.
on), lumbar back muscle strengthening, and gluteal muscle strengthening exercises are often added.

In particular, there is a close relationship between the anteversion of the pelvis and the lordosis of the lumbar vertebra, and the greater the anteversion of the pelvis, the greater the lordosis of the lumbar vertebra. In other words, when the pelvis tilts forward and the lumbosacral angle increases, the lumbar vertebra supported by the sacral vertebrae must be bent greatly forward to keep the upper body vertical. In such a state, back pain is likely to occur.

[0007] Even when the pelvis is in a normal forward leaning state, the lumbar spine is constantly applied with a force to slide forward, and a large load is applied to the ligaments, muscles, intervertebral discs, and facet joints in order to stop this. Take it. In this case, in particular, the lumbar muscles are subjected to continuous tension by the stimulation. At this time, if the pelvis is strongly inclined forward, these loads and tensions are further increased, and strong stress is applied to each tissue of the lumbar region, causing reflexive protective spasm of muscles and joint capsules, causing low back pain.

[0008] The pelvic rotation movement in the above-mentioned low back pain exercises is that the lower abdomen is rolled up while bending the lower limbs in a supine position, standing up on the knees, and indenting the abdomen and pressing the lower back to the floor. It is intended to ease the pelvic anteversion. In addition, stretching of the back muscles is to raise the head on the back, hold both knees, and keep a rounded posture like shrimp, relieve fatigue muscle tension, painful muscle tension, etc. There is action.

Further, the strengthening of the abdominal muscles is to perform abdominal muscle strengthening exercises by bending the knees, and to improve the abdominal muscles by this exercise to improve the pelvic anteversion. In addition, the stretch of the iliopsoas is to lie on your back, stretch one leg and press it so as not to get off the floor, bend the other knee and pull it to the chest, stretch the iliopsoas, This is to reduce the pelvic anteversion. The mobilization of the facet joint is also called a lateral lying exercise, which is a supine position on a bed, and the knee joint of one leg is extended while the other leg is extended. Are crossed from above toward the outside of one of the lower limbs with the knee bent, and the hip is twisted together with the pelvis to rotate from the waist to the pelvis.

[0010]

However, the above-mentioned various kinds of low back pain exercises can relieve low back pain by exercising the lower back. Guidance and assistance are needed. Patients often perform actions that are not effective for back pain, and in some cases risk performing actions that are detrimental to back pain.

For example, when performing the above-described mobilization of the facet joint, if the shoulder is lifted from the floor in the supine position, the entire lumbar part rotates from the back, and the effect on the facet joint is extremely low. Less. In addition, it is often thought that the rotation is easy if the hip is rotated in the standing position, but in this case, the rotation at both hip joints becomes almost the same, and the rotation at the lumbar spine is almost eliminated.

Accordingly, the present invention has been made to solve the above problems, and has as its object to effectively treat a patient's back pain or to prevent back pain without the need for expert guidance or assistance. An object of the present invention is to provide a device that can be designed.

[0013]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a method for treating or preventing low back pain, which is configured to perform a lower back exercise while a patient is lying on his / her back.

Features.

According to this means, the joint capsule ligament of the facet joint, the interprocess lateral ligament arriving at the lateral process, the yellow ligament arriving at the vertebral arch,
The iliopsoas ligament that arrives at the lumbosacral joint is stretched, and the ligament spasm is released. At the same time, the transversus abdominis and the multifidus are also stretched, so in addition to the three types of exercise considered to be effective for lower back pain called stretching of the lumbar spine, pelvic rotation, and lying down, mobilization of facet joints, Alternatively, the same effect as in the case of performing a lateral ling exercise can be naturally applied without performing active exercise, and can effectively improve back pain without the need for specialists and caregivers. Prevention can be achieved.

Further, since the swinging member is configured to swing by the driven-side engaging tooth surface meshed with the driving-side engaging tooth surface rotated by the drive source, the swinging member can be formed with a simple structure. Since the drive can be reliably performed, the volume occupied by the drive mechanism and the number of parts can be reduced, and the device can be made compact, lightweight, and low in cost.

It is preferable that it is comprised. According to this means, the drive mechanism can be made compact by using a drive gear as the drive side engaging portion.

In this case, the reference pitch plane of the driving gear and the tooth row of the driven-side engaging tooth surface may be appropriately formed in accordance with the swinging operation of the swinging member. In this case, the teeth of the drive gear are arranged in an arc shape (the reference pitch surface is a cylindrical surface, a conical surface, etc.), and only the driven-side engaging tooth surface provided with the teeth is formed into a curved surface shape according to the swing operation. This can further reduce the manufacturing cost. Further, as described below, a case where the driving-side engaging tooth surface is engaged with the driven-side engaging tooth surface from the rocking member side,
When the drive-side engaging portion is a drive gear having teeth arranged in an arc shape as the drive-side engaging tooth surface, the driven-side engaging surface is curved in a direction opposite to a curved direction of the guide surface. What is necessary is just to form the tooth row on the tooth surface provided with a direction.

In each of the above means, it is preferable that the driving-side engaging tooth surface is meshed with the driven-side engaging tooth surface from the rocking member side. According to this means,
Since the driving side engaging tooth surface is engaged with the driven side engaging tooth surface from the rocking member side below the rocking member, the rocking member engages with the drive system so as to be on the support surface of the support base. Therefore, there is no need to separately provide a holding means for the swinging member.

In each of the above means, the oscillating member is further provided with oscillating-side teeth formed along the oscillating direction, and the support base is provided with the oscillating-side teeth relative to the oscillating-side teeth. It is desirable to provide a supporting-side tooth row that is configured to always mesh over the entire swing range of the moving member. According to this means, the rocking member and the support base are configured to rock without slipping due to meshing between the rocking side tooth row and the support side tooth row.

It is preferable that a base is arranged, and the leg base has a movable structure limited to a predetermined range in the swing direction.
According to this means, the upper body can be laid on the upper base, and the legs can be placed on the leg base to perform the waist movement in the supine position, and the leg base has a movable structure in the swinging direction. Since the legs can also be swung with the swing of the waist, unnecessary load is not applied to the waist of the patient and sufficient exercise can be performed on the waist. Moreover,
Because the movable structure of the leg stand is limited to a predetermined range,
There is no careless amplification of leg swings.

In this case, it is preferable that the leg base is configured to be switchable between a posture approaching the swing member and a posture away from the swing member.
According to this means, when the user sits on the swinging member, the leg base can be pulled and the leg can be placed on the swinging member. Getting on and off is easy.

It is desirable that any one of the above-mentioned means additionally has the following features.

Is preferred to improve the anteversion of the patient's pelvis. In this case, when the body axis of the patient lying on the back, particularly the upper body is not horizontal, it is preferable to set the axis of the swinging member so that the waist is inclined with respect to the body axis of the upper body.

[0026] The curved shape of the guide surface may be formed such that the center of curvature is arranged above the center of the patient's waist placed on the waist rest. It is preferable to sufficiently exercise the waist to improve the improvement effect.

Further, it is preferable that a swing width adjusting means for adjusting the swing width of the swing member by the driving means and a swing speed adjusting means for adjusting the swing speed of the swing member are provided. It is preferable for exercising according to symptoms and conditions (age, physical strength, etc.). In this case, a control device for sequentially executing a plurality of types of swing steps in which the swing width and the swing speed of the swing member are changed according to a preset program is provided. Is preferred for enhancing the effect of treatment and prevention. In this case also
It is preferable that the swing member is driven so as to include a plurality of steps of sequentially swinging the waist of the patient under a plurality of different conditions in which at least one of the swing width and the swing speed of the swing member is changed. In addition, the step of driving the patient to have a large amount of exercise given to the lower back of the patient by the swing width and the swing speed of the swing member and the step of decreasing the amount of exercise are alternately performed, so that the treatment of low back pain for the patient is performed. It is preferable for enhancing the effect or the preventive effect.

Further, the swing member is provided with a downwardly facing measurement lower surface formed substantially in the same shape as the guide surface, and the support base is provided with an upwardly directed measurement lower surface formed in substantially the same shape as the support surface.

As shown in FIG. 3, the patient lies on the whole body along the upper table 40, the swinging member 10, and the leg table 50.
The upper board 40 is provided with a bed plate 41 that is inclined at a substantially constant inclination angle as the distance from the position of the swinging member 10 increases. A cushion material 42 such as a mattress, a futon, a blanket, or the like is laid on the surface of the bed board 41 as appropriate. Preferably, the inclination angle of the bed plate 41 is desirably adjusted within a predetermined angle range, for example, an angle range from horizontal to about 30 degrees. When the inclination angle of the bed board 41 is made adjustable as described above, the waist pillow 43 uses the waist pillow 43 to make a step generated at a position where the bed board 41 is moved from the upper base 40 to the swing member 10 when the angle of the bed board 41 is steep. It is preferable to make up for it.

On the surface of the oscillating member 10, a cushion material 17 is spread on the waist placing surface 11. The cushion member 17 has a shape that wraps around the patient's waist depending on the shape of the waist placing surface 11, and is configured to stably hold the patient's waist. Further, a means for fixing the waist such as a strap or a belt fixed to the swinging member 10 may be provided so that the patient's waist does not inadvertently move on the swinging member 10 during operation of the apparatus. Also,
Cushion material 17 and waist pillow 43 for covering swing member 10
It is preferable that a heater is built in the inside of the device so that the patient's waist can be warmed so as not to cool the patient's waist. Further, it is preferable that a heater is built in the leg base 50 as well.

The leg base may be a simple support base for supporting a portion centered on the back side of the thigh, but the leg base 50 of the present embodiment hinders the movement of the patient's waist as much as possible. The leg base 50 itself has a certain degree of freedom so that there is no possibility. This leg base 50 is, as shown in FIG.
A base 51 installed on the floor, a support 52 rotatably attached to the base 51, and a support 52
An upper frame 53 rotatably attached to the upper end of the upper frame 53, and a support surface portion 54 attached to the upper frame 53 and formed in a roof shape so as to support the patient's legs in a slightly bent state. . The support surface 54 is covered with a cushion material 55.

A pivot shaft 56 for connecting the base 51 and the support 52 to each other is provided at a hinge for rotatably connecting the base 51 and the support 52. The rotating shaft 56 is screwed into a screw hole provided in the shaft support 51 a of the base 51, and passes through a through hole of the shaft support 52 a provided at the lower end of the support 52. As shown in FIG. 8, the rotating shaft 56 has a flange portion 56a disposed between the shaft supporting portion 51a and the shaft supporting portion 52a. The rotating lever 5 is provided at one end of the rotating member 56.
The rotation shaft 57 is rotated by rotating the rotation lever 57, and the depth of screwing into the shaft support portion 51a can be changed.

By rotating the rotating lever 57, the rotating shaft 56
When the depth of screwing into the shaft support portion 51a is increased, the flange portion 56a is pressed against the shaft support portion 52a. As a result, the shaft support 52a is sandwiched between the flange 56a and the shaft support 51a, so that the base 51 and the support 52 can be fixed so as not to rotate relative to each other. Conversely, when the rotating lever 57 is rotated to reduce the screwing depth of the rotating shaft member 56 into the shaft supporting portion 51a, the pressing force of the flange portion 56a against the shaft supporting portion 52a is weakened, and the pressing force with respect to the base portion 51 is reduced. Thus, the support portion 52 can be rotated in the body axis direction of the patient.

With the above-described hinge structure, as shown in FIG. 3, when the patient is laid on the apparatus, the patient only has to rotate the support 52 with respect to the base 51 without moving the base 51. The position of the support surface 54 can be moved back and forth in the body axis direction of the patient in accordance with the body shape, particularly the size of the lower body. By adjusting the apex of the roof shape of the support surface portion 54 to correspond to the back side of the patient's knee by the adjusting mechanism of the support surface portion 54, the leg portion of the patient can be reliably and stably supported. Become. Prop part 52
A pair of coil springs 58, 58 for connecting between the support 52 and the upper frame 53 are attached to both sides of a hinge part that rotatably connects the upper frame 53 and the upper frame 53. These coil springs 58 hold the upper frame 53 and the support surface 54 horizontally with respect to the support portion 52 in the swing direction of the swing member 10. However, when a stress is received from the patient's leg supported by the support surface 54, the upper frame 53 and the support surface 54 are allowed to swing in the swing direction of the swing member 10 according to the direction of the stress. .

The rocking mechanism of the leg base including the above-described support 52, the upper frame 53 and the coil spring 58 makes the patient's leg also rock when the patient's waist is rocked by the rocking member 10. In order to be able to rock in the direction, the legs are fully fixed, eliminating unnecessary distortion that can occur between the lower back and the legs when the patient's lower back is exercised. Can be avoided. Specifically, in the case of a normal patient, since the weight of the lower limb is about 6 to 8 kg, stress is applied to the lower back by this weight, and the sacroiliac joint is twisted through the hip joint, which causes discomfort to the patient. There is.

It is sufficient that the swing angle of the upper frame 53 and the support surface 54 with respect to the support 52 is 5 to 30 degrees on the left and right sides, particularly about 15 degrees. If the swing angle is too small, the above problem cannot be solved. If the swing angle is too large, the legs cannot be supported, and the legs come off the support surface portion 54 to increase the risk.

In the swing mechanism of the leg base 50, the elasticity of the coil spring 58 has a function of suppressing the swing operation of the leg so that the patient's leg does not swing more than necessary. If the coil spring 58 is not provided, the leg swings with almost no resistance along with the swing of the patient's waist, and the meaning of the leg stand for supporting the leg is lost.

Next, the operation of this embodiment will be described with reference to FIGS. If the cross section of the patient's waist when the rocking member 10 is in the state shown in FIG. 5A is indicated by an ellipse drawn by a solid line in FIG. 6, the patient when the rocking member 10 rocks right and left Has a waist section like an ellipse drawn by two dotted lines. Here, point O shown in FIG. 6 represents the position of the patient's body axis. When the swing member 10 swings to the right by the rotation of the output shaft 34 of the drive motor 33, the patient's waist moves to the right while rotating clockwise, and the swing member 1
When 0 swings to the left, the patient's waist moves to the left while rotating counterclockwise.

In such a swinging motion, the swinging member 1
Position of the center of curvature P of the guide surface of the 0 reciprocates right and left along the arrow F _R, F _L. Along with this, while the waist of the patient placed on the swinging member 10 rotates, the waist center O is lifted while alternately moving left and right upward along the arrow H. Therefore, unlike a simple rotational movement of the waist, the portion from the lower lumbar vertebra to the pelvis is alternately lifted obliquely upward and leftward. Therefore, by repeating this exercise, the pelvic anteversion can be reduced, and the lumbosacral joint can be mobilized.

Here, the positional relationship between the center of curvature P of the guide surface of the swing member 10 and the center O of the patient's waist can be set arbitrarily. However, the center of curvature P is the center of the waist O
By forming the guide surface so as to be positioned above the patient, the patient's waist can be lifted right and left and upward due to the swinging of the swinging member 10 to the left and right. Can be applied particularly effectively. The guide surface does not need to have the same center of curvature P as a whole along the swinging direction as shown in the figure, and the center of curvature moves along the position of the guide surface.
That is, the guide surface may be configured in a non-arc-shaped curved surface shape.

The rocking motion extends the capsular ligaments of the facet joints, the transverse ligaments arriving at the transverse process, the yellow ligament arriving at the vertebral arch, and the iliopsoas ligament arriving at the lumbosacral joint. Spasm is released. At the same time, the transversus abdominis and multifidus are stretched. In particular, in the present embodiment, as shown in FIG. 4A, since the inclination angle θ of the axis S of the swing member 10 with respect to the horizontal plane H is provided, it is possible to effectively reduce the forward inclination of the pelvis of the patient. Can eliminate the cause of back pain.

As described above, according to the oscillating motion in the present embodiment, it is almost the same as the case where three types of motion, which are considered to be effective for lower back pain, such as stretching of the lumbar spine, pelvic rotation, and lying down, are performed. The effect of is obtained. Of these, the recumbent movement, in particular, has conventionally required considerable effort to execute, and it has been difficult to carry out accurate and effective exercise. And can be executed effectively.

In the above-described apparatus, the swing member 10 is swung right and left by the power of the drive motor. However, the drive means is not limited to the electric motor, but may be various types such as a hydraulic cylinder, an air cylinder, and a solenoid. A drive source can be used.

Further, a means for adjusting the inclination angle θ of the axis S of the swing member 10 with respect to the horizontal plane H shown in FIG. 4 may be provided. This means is performed by the inclined beam members 22 and 2 of the support base 20.
This can be realized by providing a mechanism for vertically moving the mounting position between the support beam 2 and the upper portion of the support beam 21. Further, it is also possible to realize a simple structure by attaching the support base 20 to a frame (not shown) of the apparatus 1 so as to be freely tilted.

FIG. 7 is a block diagram showing a schematic configuration of the control drive system. A power switch a, a swing width adjustment dial b, a swing speed adjustment dial c, mode switches d to f, and setting switches g and h arranged on the front panel of the control panel 31 are connected to the input interface 36. The operation state of each button is configured to be input to a CPU (central processing unit) 37. The CPU 37 is connected to a memory 37a storing operation information and the like. CPU
Although a detailed structure around 37 is omitted, the CPU 37, the memory 37a and other peripheral circuits constitute an MPU (microprocessor unit). A control signal is output from the CPU 37 to the motor drive circuit 38, and the motor control circuit 38 sends a drive signal to the drive motor 33 based on the control signal. The clockwise and counterclockwise rotation angle limits of the drive motor 33 are input to the CPU 37 via the input interface 36 by the setting switches g and h, and the motor drive circuit 38 is set to the rotation angle limit in accordance with the input value. When it reaches, the rotation direction of the drive motor 33 is reversed.

When the power switch a is pressed and turned on, the CPU 37 sends a signal to the power circuit 39 to supply a power voltage to the motor drive circuit 66. When the power switch a is pressed again when the power switch a is in the on state, the swinging operation of the swinging member is started. When the power switch a is pressed in the swinging state, the swinging operation of the swinging member is performed. Stop. If the power switch a is not pressed for a predetermined time, CP
The power is automatically cut off by a timer configured by U37.

The instruction value of the swing width adjustment dial b is input to the CPU 37 via the input interface 36, and the time for driving the rotation of the drive motor 33 in the same direction is held at a value corresponding to the instruction value. After this time,
The control signal of the CPU 37 reverses the rotation direction of the drive motor 33 via the motor drive circuit 38. Note that this time is calculated in order to realize the above-mentioned swing width instruction value in accordance with the swing speed adjustment value described below, so that the actual time is independent of the swing speed. The adjustment dial b can be adjusted according to the swing width or swing angle of the adjustment dial b. Here, the maximum value of the swing width corresponds to the rotation angle limit specified by the setting switches g and h.

The instruction value of the swing speed adjusting dial c is input to the CPU 37 via the input interface 36, and a drive voltage for determining the rotational speed of the drive motor 33 (when the drive motor 33 is a DC motor or the like). Alternatively, the driving pulse period (when the driving motor 33 is an induction motor, a stepping motor, or the like) is held at a value corresponding to the instruction value. As a result, the swing member 10 operates at the swing speed or the swing cycle corresponding to the instruction value of the adjustment dial c.

It is to be noted that the swing member 10 is provided with a downwardly facing lower surface for measurement which is formed in substantially the same shape as the guide surface, and
An upper surface for measurement, which is formed in substantially the same shape as the support surface, is provided on the upper surface, and a detection unit such as a microswitch is disposed at one predetermined portion of the lower surface for measurement or one of the upper surfaces for measurement. When moved, the detection unit may be sandwiched between the lower surface for measurement and the upper surface for measurement to detect that fact. In this case, not only the detection of the rotation angle limit by the switch but also the control of the swing width of the swing member, the swing position of the swing member is appropriately detected by a plurality of detection units, and the The drive motor can be reversed at the position.

Any one of the three mode switches d to f can be selected. When the mode switch d is selected, the general mode shown in Table 1 below is selected.
When the mode switch e is selected, the elderly mode is selected, and when the mode switch f is selected, another mode such as the elderly mode is selected, and a rocking motion pattern suitable for each mode is executed. .

[0064]

[Table 1]

For the small swing, middle swing, and large swing in Table 1, the swing width adjustment dial b and the swing speed adjustment dial c indicate the reference value (median value). In this case, the swing width (the swing angle) and the swing speed (the swing cycle) shown in Table 2 below are set in advance.

[0066]

[Table 2]

The general mode shown in Table 1 is performed for an average elderly patient, and exercises with less load on the lower back than in the middle-age mode by not performing large swings. The elderly mode is performed for young children and the elderly, and has an exercise pattern that is less burdensome than the general mode. In any mode, it is desirable to alternately repeat the swinging of the relatively light momentum and the swinging of the relatively heavy momentum in order to obtain a therapeutic effect.

In each of the above modes, the swing angle and swing of the small, medium and large swings are adjusted by adjusting the swing width adjustment dial b and the swing speed adjustment dial c. The dynamic cycle can be adjusted. Therefore,
If you have selected any of the above mode switches,
The pattern actually operated is determined by the selected mode shown in Table 1 and the indicated values of the adjustment dials b and c. When none of the mode switches is selected, only the swing operation corresponding to the instruction values of the adjustment dials b and c is continuously executed.

As described above, a simple motion of the rocking member 10 can provide an effective exercise for lower back pain to the patient's waist, but a plurality of rocking states with different rocking widths and rocking speeds can be performed. The exercise can be performed as appropriate according to the patient's age, flexibility, type of back pain, degree of back pain, and the like.

In particular, by sequentially executing different rocking states in a predetermined pattern, it is possible to induce a different cause of back pain and an improvement effect on different parts. This is because, for example, a patient or a case in which a therapeutic effect can be expected due to a small swing width and a small swing cycle is generally different from a patient or a case in which a therapeutic effect can be expected due to a large swing width and a large swing cycle. It is. In this case, a swing having a small swing width and a large swing cycle or a combination of a large swing width and a small swing cycle may be used.

Further, the therapeutic effect can be enhanced by alternately repeating the swing of the momentum during the exercise as described above. Furthermore, before starting full-scale exercise, by gradually increasing the amount of exercise from the swing of a small amount of exercise, by warming up the lower back of the patient, or by gradually reducing the amount of exercise at the end of exercise, The safety of the treatment can be improved, and the exercise load on the lower back of the patient can be reduced.

Since the shape of the swinging member 10 other than the guide surface is arbitrary, it is preferable that the waist placing surface 11 be configured to hold the patient's waist firmly. Further, a cradle-shaped one in which the guide surface is constituted by a frame member connected to a member having a waist placing surface may be used.

Further, the swinging member and the support base are provided with guide teeth and a rack that mesh with each other. However, without providing such a tooth profile, the swinging member and the support portion can be moved in the swinging direction with each other. Another engaging structure may be provided so as not to slide toward. Further, for example, a part or the whole of the back surface of the swing member is used as a guide surface, and the surface of the guide surface is received by a support surface such as a floor surface, so that the guide surface and the support surface do not slip. A rubber plate or the like may be adhered to the device.
The rocking member and the supporting portion are configured not to slide with each other in this manner, because the rocking member supporting the patient's waist slides with respect to the supporting portion, whereby the patient's waist, This is because there is a risk of causing serious damage to the spine, hip joint, and the like.

In the above embodiment, a flat support frame is provided as the support portion. For example, the support portion has a larger radius of curvature than the curved shape of the guide surface of the swing member (ie, a smaller curvature). ) It may be formed in a curved shape, and in this case, although the swinging operation is slightly different, substantially the same effect as that of the above embodiment can be given to the waist of the patient. In this case, the support portion may be curved (to open downward) opposite to the curved shape of the guide surface.

The reference pitch surface and other working surfaces of the curved rack 16 attached to the swinging member 10 are the surface of the guide strip 12b, which is the guide surface of the swinging member 10, and the guide surface, which is the support surface of the support base 20. The configuration is such that it can be driven over the entire swing range without moving the output shaft 34 of the drive motor 33 due to the shape relationship with the upper surface of the beam member 24. That is, the operation surface of the curved rack 16 is curved in a direction opposite to the direction of curvature of the guide surface of the swing member 10. As described above, since the swinging operation of the swinging member 10 is absorbed by the meshing portion between the output gear 35 and the curved rack 16, the driving mechanism itself can be greatly simplified. Can also be reduced. Further, the number of components of the drive system can be reduced, the volume occupied by the drive system can be reduced, the drive resistance can be reduced, and the durability can be easily improved.

The combination of the output gear 35 fixed to the output shaft 34 of the drive motor 33 and the curved rack 16 can be variously set. For example, even in the case of the present embodiment, an elliptical gear or another modified gear is used in place of the output gear 35, and instead, the curvature of the reference pitch surface of the curved rack 16 is changed, or a flat A suitable rack can also be used. That is, in the drive system, the shape of any one of the working surfaces of the transmission path from the drive source to the swing member is formed so as to compensate for and absorb the position change caused by the swing operation of the swing member. Just do it. This greatly simplifies the mechanical structure other than the action surface.
