DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating back pain, and more particularly to an apparatus for treating back pain by exercising the lower back.

[0002]

2. Description of the Related Art The number of patients who come to the hospital for back pain is very large even in the daily practice of orthopedic surgery.
Occupies 0%. 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, facet joints, muscles, ligaments, and nerves (tumors, infections, deformities, 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 ways to avoid it 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 treatments, exercise therapy is effective for chronic low back pain and recurrent low back pain, and is most often used for so-called low back pain. Also,
In recent years, this exercise therapy has been used for lumbar disc herniation and lumbar spondylolisthesis, etc. after the acute stage, and recently, it has been tried for almost all back pain diseases except tumors and inflammatory diseases.

[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) and strengthening the lumbar back muscles and gluteal muscles 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 if the pelvis is in a normal forward leaning state, the lumbar spine is constantly subjected to a sliding 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 particular, the lumbar muscles are subjected to continuous tension by 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] Pelvic rotation in back pain exercises described above is to raise the lower abdomen while raising the knees in a supine position, indenting the abdomen and pressing the lower back to the floor. , To alleviate the pelvic anteversion. Also,
With lumbar spine stretching, lift your head on your back,
It holds both knees and keeps a curled posture like a shrimp, and has the effect of relieving fatigue muscle tone, painful muscle tone, and the like.

[0009] In addition, the strengthening of the abdominal muscles is performed by bending the knees to perform abdominal muscle strengthening exercises. In addition, the iliopsoas stretch lies on your back, stretches one leg and pushes it so as not to get off the floor, and bends the other knee and draws it to your chest. Is to decrease the forward lean of the vehicle. And the mobilization of the facet joints is also a lateral lying exercise
In a supine position on the bed, the knee joint of one leg is extended, and the other leg is bent over the knee with the knee bent and crossed from above toward the outside of the lower leg, and together with the pelvis By twisting the waist, it rotates from the waist to the pelvis.

[0010]

The above-mentioned low back exercises can relieve low back pain by exercising the lower back, but in order to carry out these exercises effectively, detailed guidance and assistance from an expert is required. Becomes 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 easy to think that it is easier to rotate the waist in the upright position, but in this case, the rotation at both hip joints is almost the same, and the rotation at the lumbar spine is almost eliminated.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an apparatus capable of easily performing an effective exercise for back pain treatment without the guidance and assistance of a specialist. Is to do. Another object of the present invention is to realize a novel apparatus that can perform various exercises performed by various conventional low back pain exercises with a single apparatus using a single position. Another object of the present invention is to provide an automatic device capable of treating back pain more effectively than before.

[0013]

In order to solve the above-mentioned problems, the present invention provides a device for treating low back pain by exercising the lower back while the patient is lying on his / her back.
A waist resting surface formed on the front side for resting the patient's waist, and an upper line formed on the back side of the waist resting surface and having an axis substantially parallel to the patient's body axis, opened upward. A swing member having one or a plurality of guide surfaces having an arc-shaped cross section, and supporting the guide surface of the swing member so that the swing member can swing, and being larger than the guide surface. A support having a curved or flat support surface.

According to this means, the waist can be moved obliquely upward while the waist is tilted left and right by arranging the waist on the rocking member and rocking the rocking member right and left. Can perform the same movements as lumbar spine stretching, pelvic rotation, and mobilization of facet joints, and is effective in relieving low back pain. In particular, mobilization of the facet joint among the above exercises involves considerable difficulty in execution, and especially in the elderly, it is not possible to perform sufficient rotation due to weakness in muscle strength around the abdomen and hip joints, and perform effective exercises Is difficult, but it can be performed very easily, accurately and effectively by using the above-mentioned apparatus.

Here, the guide surface of the swinging member,
It is preferable that mutually intermeshing tooth profiles are formed on the support surface of the support base in the swing direction. In this case, since the swing member and the support table are engaged with each other, the swing member can be swung to the left and right with a stable and light force.

It is preferable that an angle adjusting means is provided for changing the vertical inclination angle of the waist-mounting surface of the swinging member in the axial direction. In this case, it is possible to appropriately correct the anteversion of the pelvis according to the symptom by setting the vertical swing angle of the axis of the swing member.

A drive mechanism connected to the back side of the swing member for swinging the swing member in a curved direction of the guide surface; and a swing mechanism for adjusting a swing width of the swing member. It is preferable to provide width adjusting means and / or swing speed adjusting means for adjusting the swing speed of the swing member. In this case, the swinging member can be automatically swung right and left by the driving mechanism, and the swing width and / or the swing speed is adjusted by the swing width adjusting means and / or the swing speed adjusting means. It is possible to exercise the patient by appropriately adjusting various patients and cases in consideration of the patient's age, type, degree, and site of back pain.

In this case, there is further provided a control device for sequentially executing a plurality of stages of oscillating motion in which the oscillating width and / or the oscillating speed of the oscillating member is changed according to a predetermined program set in advance. Is desirable. By sequentially executing various rocking movements by this control device, it is possible to effectively act on different causes and parts and reduce the exercise load on the patient.

Are designed to reciprocate the drive plate 62 via a transmission belt. As shown in FIG. 3, an engagement shaft 62a is attached to the drive plate 62, and the engagement shaft 62a is fitted in a vertically extending elongated hole 16a formed in the drive lever 16. The transmission belt 64 is bridged by an output pulley 63 of the drive motor 61 and a support pulley 65 attached at a position facing the output pulley 63.

As shown in FIG. 2, the patient lies on his / her 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 board 41 which is inclined at a substantially constant inclination angle as it moves away from the position of the swinging member 10, and a cushion material such as a mattress, a futon, a blanket or the like is provided on the surface of the bed board 41 as appropriate. Lay 42. 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. In addition, as described above, the bed board 41
When the angle of inclination of the bed board 41 is made steeper, it is preferable that the waist pillow 43 fills 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 made steep.

On the surface of the oscillating member 10, a cushion member 17 similar to the above is laid on the waist placing surface 11. It is preferable from the viewpoint of the stability of the waist that the cushion member 17 is formed to be thick at the left and right curved portions and relatively thin at the central waist so as to enclose the waist of the patient. Further, a means for fixing the waist such as a strap or a belt may be provided so that the waist does not inadvertently move on the swinging member 10 during exercise by the present apparatus.

A flat portion 51 is formed on the surface of the leg base 50 near the swing member 10, and the swing member 10 of the flat portion 51 is formed.
An inclined surface 52 is formed on the side away from the side. The surfaces of the flat portion 51 and the inclined surface 52 are covered with the cushion material 53 similar to the above. Flat part 51

In the above device, a heater is built in the cushion member 17 and the waist pillow 43 for covering the swinging member 10 shown in FIG. 2 so that the patient's waist can be heated so as not to cool it. It is preferable to configure. As shown by the dotted line in FIG. 2, instead of the leg base 50, a leg attached to the tip of a connecting rod 55 connected to the left part of the support base 20 and arranged at a slight distance from the support base 20. The mounting table 56 can also be used. This leg rest 56
According to this, since there is a predetermined space between the support 20 and the patient, the patient stands across the connecting rod 55 within this space and sits on the waist mounting surface 11 of the swinging member 10 as it is. Thereby, the supine posture shown in FIG. 2 can be easily taken.

The basic operation of the present embodiment will be described with reference to FIGS. FIG. 3 shows a case where the swing member 10 is at a reference position on the support base 20. Transmission belt 6
The drive plate 62 connected to the drive plate 4 is located substantially at the center of the support base 20, and the engagement shaft 62a fixed to the drive plate 62 engages with the upper part of the long hole 16a of the drive lever 16 located at the center. doing.

When the drive plate 62 moves to the left via the transmission belt 64 by operation of the drive motor, the drive lever 16 engaged with the engagement shaft 62a also moves to the left as shown in FIG. The swing member 10 is inclined rightward. Further, as shown in FIG. 5, when the drive plate 62 moves to the right, the drive lever 16 also moves to the right. Therefore,
By reciprocating the drive plate 62 to the left and right, the swing member 10 has its guide gears 13, 13 mounted on the racks 25, 26.
Therefore, it swings right and left while maintaining the meshing of the gears without shifting or sliding in the left-right direction.

As shown in FIG. 3 to FIG. 5 and FIG. 8, the position of the center P of the guide surface 12 of the rocking member 10 moves right and left as shown by arrows F _R and F _L in this rocking motion. At the same time, the center O of the waist placed on the swinging member 10 is lifted to the left and right and upward while rotating as shown by the arrow H, so that unlike the simple rotational movement of the waist, the region from the lower lumbar vertebra to the pelvis Will be lifted diagonally right and left. Therefore, the pelvic anteversion is likely to decrease, and the lumbosacral joint is mobilized.

The rocking motion extends the capsular ligaments of the facet joints, the transverse ligaments arriving at the transverse processes, the yellow ligaments arriving at the vertebral arch, and the iliopsoas ligaments arriving at the lumbosacral joint. Spasm is released. At the same time, the transversus abdominis and multifidus are stretched.

As described above, according to the rocking exercise in the present embodiment, it is almost the same as when three kinds of exercises, 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 is particularly difficult to perform,
Although it is difficult to carry out accurate and effective exercise, it can be performed very easily, accurately and effectively by using the above device.

In the above-described apparatus, the swinging member 10 is swung right and left by the power of the drive motor, and the patient lying on the top can passively perform the above-described movement.
In a device having a similar oscillating member and a supporting base, the oscillating member 10 is not provided with the driving system 60 and is activated or manually.
Can be swung right and left. In this case, the same effect as described above can be obtained. For example, the patient may grasp the left and right ends of the swinging member 10 with his / her hand and swing the swinging member 10 left and right.
May be manually swung.

FIGS. 6 and 7 show means for adjusting the vertical inclination of the axis of the swinging member 10. As shown in FIGS. Support stand 2
The vertical axis 21 of the swinging member 10 is moved from a substantially horizontal state by moving the support frame 23 fixed by fixing bolts 24 into and out of the vertical groove 21a formed in the It can be changed to the inclined state where the side of 50 is raised. The fixing bolt 24 is attached to the frame 21.
Is inserted through one of the three positioning holes 23a, 23b, and 23c formed in the support frame 23 fitted in the vertical groove 21a through an insertion hole 21b formed horizontally in the vertical direction, and faces the insertion hole 21b. And is fixed by being fitted into the support hole 21c formed in the hole.

FIG. 7 shows the fixing bolt 24 with the positioning hole 23a.
, The axis Q of the swinging member 10 is kept substantially horizontal. Even in this state, the upper base 40
The posture can be corrected in a direction in which the pelvic forward inclination is reduced by the inclination angle of the pelvis. However, in order to more strongly correct the pelvic forward inclination, as shown in FIG. It is more effective to set the inclination angle θ in the direction so that the patient takes a posture in which the waist is rounded.

FIG. 9 is a block diagram showing a schematic configuration of the control unit 30. Power switch 3 arranged on the front panel
1. The swing width adjustment dial 32, the swing speed adjustment dial 33, and the mode switches 34, 35, 36 are connected to an input interface 37, and the operation state of each button is input to a CPU (central processing unit) 38. It is configured to be. The CPU 38 is connected to a memory 39 storing operation information and the like.

A control signal is output from the CPU 38 to the motor drive circuit 66, and the motor control circuit 66 sends a drive signal to the drive motor 61 based on the control signal. As shown in FIGS. 3 to 5, micro switches 67 and 68 are attached to the movement limit point of the drive plate 62, and the status signals of these micro switches 67 and 68 are also transmitted via the input interface 37. It is input to the CPU 38. When the swing member 10 reaches the left and right limit position (for example, a swing angle of 40 degrees), the control unit 30 receives the state signals of the micro switches 67 and 68 and stops the rotation of the drive motor 61 or reverses the rotation. It has become.

When the power switch 31 is pressed and turned on, the CPU 38 sends a signal to the power circuit 69 to supply the motor drive circuit 66 with a power voltage. When the power switch 31 is pressed again when the power switch 31 is in the ON state, the swinging operation of the swinging member starts. When the power switch 31 is pressed in this swinging state, the swinging operation of the swinging member starts. Stop. If the power switch 31 is not pressed for a predetermined time, the power is automatically shut off by a timer configured by the CPU 38.

The instruction value of the swing width adjustment dial 32 is input to the CPU 38 via the input interface 37.
The time for driving the rotation of the drive motor 61 in the same direction is held at a value corresponding to the indicated value. After the elapse of this time, the control signal of the CPU 38 reverses the rotation direction of the drive motor 61 via the motor drive circuit 66. Since this time is measured using the following adjustment value of the swing speed as a basic unit, it can be adjusted according to the actual swing width or swing angle regardless of the swing speed.

The instruction value of the swing speed adjustment dial 33 is input to the CPU 38 via the input interface 37, and a drive voltage for determining the rotation speed of the drive motor 61 (when the drive motor 61 is a DC motor or the like). Alternatively, the driving pulse period (when the driving motor 61 is an induction motor, a stepping motor, or the like) is held at a value corresponding to the instruction value.

One of the three mode switches 34, 35, and 36 can be selected. When the mode switch 34 is selected, the general mode and the mode switch 35 shown in Table 1 below are set. When selected, the middle age mode is selected, and when the mode switch 36 is selected, another mode such as the elderly mode is selected, and a rocking motion pattern suitable for each mode is executed.

[0045]

[Table 1] General mode Middle age mode Elderly mode Small swing 20 seconds Small swing 20 seconds Small swing 90 seconds Medium swing 90 seconds Medium swing 90 seconds Medium swing 90 seconds Small swing 20 seconds Small swing 20 Second Small swing 20 seconds Medium swing 90 seconds Large swing 60 seconds Medium swing 60 seconds

The small swing, the middle swing, and the large swing shown in Table 1 are described below in advance when the swing width adjustment dial 32 and the swing speed adjustment dial 33 indicate the median value, respectively. The swing width (the swing angle) and the swing speed (the swing cycle) shown in Table 2 are set.

[0047]

[Table 2] Small swing Medium swing Large swing Oscillation angle 10 degrees left and right 15 degrees left and right 30 degrees left and right Swing cycle 0.6 seconds 1.2 seconds 2.0 seconds

The general mode shown in Table 1 is performed for an average elderly patient, and exercise is performed with less load on the lower back than in the middle age mode by not performing a large swing. 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 angle of the small swing, the middle swing, and the large swing are adjusted by adjusting the swing width adjustment dial 32 and the swing speed adjustment dial 33. The dynamic cycle can be adjusted. Therefore, when any one of the mode switches is selected, the operation pattern is determined by the selected mode shown in Table 1 and the indicated values of the adjustment dials 32 and 33. If none of the above mode switches has been selected, a swing operation is performed according to the instruction values of the adjustment dial 32 and the adjustment dial 33.

As described above, according to the present apparatus, a movement effective for low back pain can be executed only by the simple swing of the swing member 10, but a plurality of swings having different swing widths and swing speeds can be performed. By applying exercise in a moving state, treatment can be appropriately performed according to the patient's age, flexibility, type of back pain, degree of back pain, and the like.

In particular, by sequentially executing different swinging states in a predetermined pattern, it is possible to induce an improvement effect on different causes of back pain and 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 combination of a small swing width and a large swing cycle, a large swing width and a small swing cycle, or the like may be used.

In addition, the therapeutic effect can be improved by repeating the swing of the amount of exercise alternately 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.

In the above embodiment, the swinging member is constituted by a saddle-shaped plate-like member which is entirely curved. However, if only the guide surface forming the guide gear is formed in an arc shape, Other parts may be of any shape, for example, the waist mounting surface is relatively flat, and the guide surface is constituted by two arc-shaped frame members connected to the waist mounting surface, and the guide gear extends along the frame member. It may be a cradle-shaped one formed by pressing.

The swinging member and the support table are provided with a guide gear and a rack which mesh with each other. However, without providing such a tooth profile, for example, a part or the whole of the back surface of the swinging member is guided. Alternatively, a support surface for receiving the guide surface may be provided on the support table, and a rubber plate or the like may be attached to the surface so that the guide surface and the support surface do not slip.

The rack formed on the support base is formed on a flat support frame in the above embodiment.
The support surface or the rack may be formed on a curved surface having a larger radius of curvature than the guide surface of the swinging member. In this case, the swinging member can perform the same operation as described above.

The drive system can be appropriately composed of various cylinders, crank mechanisms, cam mechanisms, and the like, in addition to the above-described mechanisms such as the drive motor, the transmission belt, and the connection between the shaft and the long hole. Also, the control unit may use a programmable controller or a control circuit configured to be adjustable with a simple variable resistor.

[0057]

As described above, according to the present invention, the waist is disposed on the swinging member, and the swinging member is swung right and left, so that the waist can be moved obliquely upward while tilting left and right. Therefore, it is possible to perform the same operations as the back and back muscle stretching, the pelvic rotation movement, and the lying down movement as back pain treatment exercises, which is effective in relieving back pain. In particular, among the above-mentioned exercises, especially the recumbent exercise involves considerable difficulty in execution, and it is difficult to carry out an accurate and effective exercise, but by using the above-described device, it is extremely easy to use,
Moreover, it can be executed accurately and effectively.
