Description

The present invention relates to an improvement of a stretch base on which a trainee rests in a supine position and performs trunk muscle stretch exercise, relaxation exercise, and the like.

The human spine bends forward at the neck (front bay), bends back at the chest (back bay), and lumbar at the front bay, forming an S-shape as a whole so that the load is not concentrated in part. It has become.
However, since a person often lives in a standing or sitting position, the weight of the head is applied to the neck, the weight of the arm is applied to the shoulder, and the weight of the entire upper body is applied to the back of the waist. In addition, since an unnatural posture is often continued for a long time by desk work or the like, stress often concentrates on a local area such as a neck or a waist. For this reason, the trunk is always stressed, and abnormalities such as muscle stiffness and pain tend to occur.

Massage, hyperthermia and other physical therapies are used to treat stiffness and pain, but these effects are difficult to reach deep in the trunk, so even if an abnormality is noticed, it cannot be treated sufficiently and left as it is. Often.
If such an abnormality persists, the muscles further harden and blood flow decreases, affecting the nervous system, which further contracts the muscles, lowers blood flow, and amplifies pain. Formed and pain becomes chronic.

In addition, continuous muscle tension also affects bones and joints, limiting the range of motion of the joints and causing distortion in the joints. For example, if the abnormal tension of the muscles at the back of the lumbar spine persists, the lumbar spine becomes an excessive anterior bay (an excessive bay), and stress may concentrate here to cause back pain.
When such abnormalities are prolonged, the disease becomes more serious and chronic, and causes another disease, so the treatment is important.

Recently, a stretch table has attracted attention as an effective treatment for such abnormalities in the deep muscles of the trunk. The stretch table here is called a stretch pole in Japan, or a FOAM ROLLER in the United States. The shape is a cylinder with a diameter of about 15 cm and a length of about 90 cm as shown in FIG. A mold, or a semi-cylindrical type obtained by dividing this cylinder vertically in half. There are various sizes and shapes including for children. FIG. 3 (B) is a side view when the trainee is placed on the stretch table, and FIG. 3 (C) is a front view of the trainee viewed from the head side.
When using this, as shown in FIG. 3 (B), place the head to the buttocks in the supine position on the stretch base, open the legs a little and place on the floor to stabilize the posture, As shown in Fig. 3 (C), move the trunk as shown by arrow A or move the arms and legs to perform joint exercises such as the shoulder joint, hip joint, sacroiliac joint, etc. To do.

A similar device is a device that uses the curvature of the table to warp the back, correct the posterior bay of the thoracic vertebra, and stretch the body (for example, see Patent Document 1).
There is also a device that performs a motion of the thorax on a bed to correct and stretch the posterior bay of the thoracic vertebra (see, for example, Patent Document 2).
The following is described with reference to the drawings.
Registered Utility Model Publication No. 3045262 Published Patent Publication No. 2002-325783

FIG. 3 is an example of a conventional stretch table, (A) is an external view of two types of stretch tables, (B) and (C) are a side view and a front view when placed on a semi-columnar stretch table ( Only the trunk is shown). Here, a semi-cylinder-shaped stretch table will be described, but a column-shaped stretch table is substantially the same.
The stretch base used here is a semi-cylindrical shape having a length of about 90 cm and a diameter of about 15 cm, and as shown in FIG. 3B, can be placed from a person's head to the buttocks.
When placed in the supine position, the spinal column is directly compressed due to the structure of the platform, causing pain and discomfort. For this reason, the base is often softened moderately.

When a person puts on the soft stretch table, the table is slightly crushed and distorted. As shown in FIG. 3C, the trunk is supported in a range of width L across the spinal column.
On the back of the person, there are left and right protruding parts (hereinafter referred to as “the most convex parts”) where the muscles are raised, in the vicinity of the scapular line slightly outside the paravertebral line (refer to FIG. 6). ). It is known that when the width L is about the distance between the left and right most convex portions, effective stretching exercise and relaxation training are possible. For this reason, the diameter of the base is determined so that the width L is the distance between the left and right most convex portions. Usually, L is about 10 cm. The paravertebral line is a line connecting the ends of the vertebrae (see FIG. 6). However, muscles and stretch tables are soft and cause some distortion, so this dimension is an approximate guide.
When such a stretch base is used, the trunk can be warped backward as indicated by an arrow A in FIG. For this reason, the spinal column muscles can be stretched. Further, it is possible to perform thoracic movement as described in Patent Document 2, stretch the related muscles, and correct the folds before and after the spinal column.
The height of the base is about 15 cm, and the shoulder joint can be moved to almost the full range of motion by moving the arm backward from the body. For this reason, almost all muscles related to the shoulder joint can be stretched.

When using, as shown in Fig. 3 (B), put the head to the buttocks on the stretch base and be in the supine position, open the legs lightly and place on the floor to stabilize, and in this posture, stretch exercise and relaxation training To do.
The stretching exercise referred to here is to perform joint movements such as the spinal column, shoulder joint, hip joint, sacroiliac joint, etc. on the stretch base and stretch the muscles related to this joint. For example, if you put your palm on the floor and move it like drawing an arc, or if you move your arm three-dimensionally to the full range of motion of the shoulder joint by protruding the arm to the front of the face or raising it to the head side, All muscles related to shoulder joint movement can be stretched. Stretching muscles can relieve muscle tone, increase blood flow, relieve pain, and improve joint range of motion limitations.

Similarly, when a leg is moved for hip joint exercise, muscles related to the exercise such as the hip joint and the sacroiliac joint can be stretched.
As for the spinal column, it is possible to stretch the paraspinal muscles (standing muscles) by performing exercises such as the extremities, the rib cage, and the trunk.

You can also practice relaxing on the stretch table. This is to relax while imagining that the tension of the whole body is removed on the stretch table to eliminate the tension of the muscles, and this makes it possible to relax the tensioned muscles. In addition, when this relaxation is performed, self-load is applied to the spinal column, the front bay and the rear bay are corrected, and, as shown by the arrow A in FIG. Paramuscles are stretched. The force in the direction of arrow A in FIG. 3C includes a force when performing self-motion and a force acting by gravity when relaxed.

FIG. 4 is a device of Patent Document 1, FIG. 4 (A) is a perspective view thereof, and FIG. 4 (B) is a side view showing a state of actual use. The device of the present invention is an arch-shaped pedestal that is raised in the vicinity of the thoracic vertebra and wider than the trunk. As shown in FIG. 4B, the vertebra is stretched on the pedestal and stretched on the vertebrae. It will correct the rear bay. There are many thoracic spine stretching devices similar to this device, such as JP-A-7-250920.
However, this device is not directly related to the present invention.

Fig. 5 shows the device of Patent Document 2. The width of the bed is about the trunk, resting on it in the supine position, holding the arm (8 in the figure) with your hand, moving the thorax, and stretching the related muscles It corrects the posterior bay of the thoracic spine. If the thoracic spine becomes excessively posterior, the rib cage will be compressed and lung function will be reduced. This stretch can also be used to improve these diseases. This device is also not directly related to the present invention.

When exercise is performed in a supine position on a conventional stretch table as shown in FIG. 3, since the table has a (semi) cylindrical shape, the spine directly hits the table, causing pain and discomfort.
In order to avoid this inconvenience, some conventional stretch bases have a soft surface to avoid pressure on the spinal column. However, even if it is soft, pain and discomfort may occur depending on the exercise and depending on the person. When pain occurs, there is a problem that a satisfactory therapeutic effect cannot be obtained because no further exercise is possible.

On the other hand, when the stretch table is softened, the spinal column is less stimulated, but there is a problem that the original purpose of stretching the muscle cannot be sufficiently achieved.
In general, if there is abnormal tension in a muscle that moves a joint, the range of motion of the joint is restricted in a region corresponding to the muscle, and joint motion cannot be performed in this range. For this treatment, it is effective to stretch exercised muscles in a region where the range of motion is restricted, and stretch the muscles that are in tension.
In the stretch table, the trunk can be fixed to the stretch table and the limbs can be moved, so it is suitable for stretching muscles related to joints in the trunk, such as shoulder joints and hip joints.
However, when performing joint range-of-motion expansion training using a conventional soft stretch base, the stretch base is distorted before the muscle is stretched and the joint range of motion expansion training is not possible because the muscles are stretched before stretching. Can't stretch.
For example, if the muscle that extends when the arm is moved backward is abnormally tensioned, the arm cannot be moved backward beyond a certain angle. This muscle stretching can be done by training to move the arms backwards. When this exercise is performed on a soft stretch base, as shown in Fig. 3 (D), when the arm is moved backward, the stretch base is distorted before the shoulder muscles are stretched, and the trunk is tilted. Because it cannot be obtained, the target muscle may not be stretched with a soft stretch base.
That is, the conventional stretch table is soft and has a problem that it cannot be stretched sufficiently.

In this way, the stretch table should be able to perform the necessary exercises sufficiently without causing pain or discomfort without squeezing the spinal column, and the necessary stretch exercises and relaxation exercises should be performed sufficiently. It is required to be able to do it.

Although the device of Patent Document 1 can stretch and correct the posterior bay of the thoracic vertebra, it cannot stretch other muscles such as shoulder joints, hip joints, and lumbar vertebrae.
The device of Patent Literature 2 can stretch and correct the posterior bay of the thoracic vertebra and stretch the thorax, but does not have any other function of the stretch table.

An object of this invention is to provide the stretch stand which can perform an effective stretch exercise without the compression stimulus to a spine.

Therefore, in the first aspect of the present invention, the stretch table is provided with a recess in a portion where the spinal column hits in the longitudinal direction, or this portion is softened so as not to press the spine.
In the invention described in claim 2, when the stretching exercise and the relaxation exercise are performed, the stretch table is hardened so as not to be distorted by the exercise so that the effective stretching and relaxing can be performed.

According to the stretch table of the first aspect of the present invention, since the spinal column is not compressed, pain and discomfort do not occur, and sufficient effective stretching exercise and relaxation training can be performed.
According to the second aspect of the present invention, since the table is hardened, the table is not distorted even if a stretching exercise is performed, so that a sufficient joint movement can be performed. Actually, it is impossible to realize the distortion, but it is sufficient that the stretching movement can be sufficiently performed within a necessary range even if it is somewhat distorted.
For this reason, even if there is a relatively strong muscle tone that could not be stretched enough in the past, it will be possible to stretch more effectively, increasing blood flow, reducing pain, The range of motion of the joint can be improved more effectively.

An embodiment of the present invention is shown in FIG. 1A is a perspective view of the apparatus, FIG. 1B is a side view when a person is placed on a stretch table, and FIG. 1C is a front view seen from the head side (note that the head is filled in). Absent). In the figure, reference numeral 1 denotes a stretch table of the present invention, and reference numeral 2 denotes a person who receives treatment on this.
The stretch base is a length that can be placed from a person's head to the buttocks, and is semi-cylindrical so as to be stable during use. According to the invention of claim 1, a recess is provided in a portion that the spinal column hits. Yes. In the example of FIG. 1, the bottom surface of the stretch base is flat, but any shape may be used.
The width L1 of the concave portion of the table is larger than the distance between the center line of the spinal column and the paravertebral line so that the spinal column is not compressed.
The width L of the table is set to support the most convex part where the slightly outer muscle of the paravertebral line swells most backward. This is about the same as the width L for supporting the body of the conventional stretch base shown in FIG. It is said that this range allows the most effective exercise and training both empirically and theoretically.

However, in the first aspect of the present invention, since the concave portion is provided in the portion where the spinal column abuts or the portion is softened so that the spinal column is not compressed by the stretch base, L1 is the paravertebral line from the center line of the spinal column. However, the width L is not limited. However, when L increases, it becomes difficult to perform the movement as indicated by arrow A in FIG.
If the width L2 of the part supporting the person on the table is too small, the load concentrates on the part and hurts, so it is desirable to make it wide enough not to hurt. Supporting from the slightly outside of the paravertebral line to the vicinity of the most convex part of the back does not cause pain due to support, and as described above, there is no pain due to spinal compression and effective training is possible. In FIG. 1, the concave portion is provided so that the spinal column does not hit the cylinder, but the shape of the L2 portion that supports the body is not limited. As shown in FIG. 2, it may have any shape such as a plane or an ellipse. However, since the exercise is performed on a table, it is preferable that the device is easy to move and has no risk of being injured or causing pain. The shape of the recess is not limited.
When the concave portion is softened, it should be softened so as not to hurt when the spine hits. This member may be a flexible material, and may be a soft gel. Usually, a recess is provided or the recess is softened, and the entire table is covered with a cover. The cover should be soft. Preferably, it has elasticity.

According to the invention of claim 2, the hardness of the table is made harder than the conventional stretch table. When performing a stretching exercise on a table, it is sufficient that sufficient articulation can be achieved and a stretching effect can be obtained even if it is somewhat distorted. Depending on the height of the table, it is necessary to be able to move the extremities to the full range of motion even when the table is distorted to the maximum. Specifically, it is sufficient that the hardness is about the same as that of ordinary polystyrene foam.

As shown in FIG. 1 (B), a person receiving treatment is placed in a supine position by placing his head to the buttocks on a stretch base, and the legs are slightly opened and placed on the floor to take a stable posture.
In this state, stretch your muscles by moving your limbs and trunk, or relax yourself by relaxing.

Conventional devices have a soft surface, but due to the structure, compression of the spine is unavoidable, which can cause pain and discomfort, which limits movement and reduces therapeutic effectiveness. It was.
On the other hand, since the stretch table of the present invention does not press the spinal column, pain, discomfort, and uncomfortable feeling do not occur even if stretch exercise or relaxation training is performed. For this reason, it is possible to achieve a desired effect by performing necessary exercises sufficiently.

On the stretch table, for example, if the arm is moved and the joint movement is performed within the entire range of motion of the shoulder joint, all the muscles related to the shoulder joint can be moved, that is, stretched.
If there is abnormal tension in a part of the muscle that moves the shoulder joint, the range of motion of the joint is limited in the region where the muscle acts. In order to treat this, it is possible to improve the range of motion limitation of the joint by performing an effort exercise in a region where the range of motion is restricted and stretching a muscle that is tense. Stretching relieves muscle tone, improves joint range of motion, improves stagnant blood flow, and relieves pain.
When trying to perform joint movement in a region where the range of motion is restricted, the muscles that are tense become resistance and the trunk tries to move without moving the joints. At this time, since the conventional stretch table is soft, if the arm is moved in the range of motion restriction, the trunk moves before the joint moves, the table is distorted, and the strained muscle cannot be stretched.
On the other hand, since the stretch table of the invention according to claim 2 is hard, even if the arm is moved in the movable range restricted region, the table is not distorted. For example, even if the shoulder joint motion is performed by moving the arm, the shoulder joint The entire range of motion can be exercised, and when the arm A is moved backward (in the direction of arrow F) as shown in FIG. 3D, the arm does not hit the floor E and cannot be moved in the entire range of motion. Since the range of motion of the joint can be expanded while the trunk is fixed to the platform, the muscles in tension can be effectively stretched.

Similarly, when a hip joint motion is performed by moving a leg, muscles related to the hip joint motion can be effectively stretched to the deep part.
The spine and limbs are connected by muscles, and the vertebrae are connected by muscles. For this reason, when the exercise | movement of a predetermined limb is performed using the stretch stand of this invention, the spinal column muscles can also be stretched.
It is also possible to stretch the thoracic and thoracic vertebra muscles by exercising as shown in FIG.

In addition to stretching the muscles by the stretching exercise as described above, the stretching stand of the present invention can also perform relaxation training. When you relax on the stretch table of the present invention and relax while imagining your muscles to lose tension, you can relax your muscles. When this relaxation takes place, the spine is self-loaded, the neck and lumbar anterior bays and the chest posterior bay are corrected, and the paravertebral muscles are stretched. Further, since the force as shown by the arrow A in FIG. 1C is applied by its own weight, the paraspinal muscles, the rib cage muscles, and the like can be stretched.

Another embodiment of the present invention is shown in FIG. This figure is an example of a front view seen from the head side of the stretch base.
FIG. 2A shows a stretch base having a trapezoidal cross section, FIG. 2B shows a flat plate provided with legs, and FIG. 2C shows an elliptical example. In any case, according to the first aspect of the present invention, a concave portion is provided in a portion where the spinal column abuts to support the most convex portion of the back portion. Instead of providing a recess, this part may be softened.
The width L and the size of the recess in FIG. 2 are approximately the same as those in the embodiment of FIG.
The length should just be a grade which a buttocks mounts from a head.
Further, according to the invention described in claim 2, the table is hardened so that effective stretching can be performed. The hardness may be the same as in the embodiment of FIG.
The shape of the surface that receives the human body does not matter.
