Description

The present invention relates to a foam molding, which is particularly suitable to allow the user to solve independently and without assistance in the everyday life blocks on the vertebral joints lying down, sitting or standing up.

The main cause of chronic back pain is poor erection. Back pain is usually not caused by muscle weakness of the back muscles, the cause is very often that the muscles are in a permanent state of stress, to achieve the necessary extension. That is, the back muscles are constantly trying to bring the vertebral joints into their intended erection. A painful overload is the result. However, a back muscle is not able to stretch blocked joints, because a blocked joint is stiff and usually limited in its joint mobility. Therefore, a targeted stretching mobilization of the vertebral joints to achieve relief.

Autofunctional spinal erection

• – leichte Streckfähigkeit der Wirbelgelenke (physiologische Gelenkadhäsion)
• – keine blockierten Wirbelgelenke
• – ausreichende Verteilung der Gelenkschmiere (Synovia) zwischen den Gelenkpartnern
• – schmerzfreie Bewegungsmuskulatur
• – schmerzfreie Haltemuskulatur (tiefliegende Rückenmuskeln)
• – keine entzündlichen Wirbel, Wirbelgelenke, Bandscheiben und Nervenwurzeln

By the term "autofunctional spinal alignment" is meant the ability of the spine to bring itself into a vertical balance. This is only possible under the following conditions:

• - slight stretchability of the vertebral joints (physiological joint adhesion)
• - no blocked vertebral joints
• - adequate distribution of synovial fluid (synovial fluid) between the joint partners
• - painless motor muscles
• - pain-free holding muscles (low-lying back muscles)
• - no inflammatory vertebrae, vertebral joints, intervertebral discs and nerve roots

The muscle always responds to the condition of the joints. If a joint shows a restriction of movement (contracture), the muscles nevertheless try to move the joint. If this is difficult or limited, the muscles react with mostly painful tension. By a constantly tense muscles increases the risk of muscle strain z. B. Lumbago (lumbago) and Cervico (stiff neck).

The muscles are not able to mobilize the vertebral joints, but it must be assumed that a muscle, in order to stay healthy and thus pain-free, requires a well-articulated joint function.

Object of the invention

The erection of the spine is controlled by the sternum. A lowering of the breastbone is given when sitting on a chair, armchair and car seat by the convex shape of the back seat. In this position, the spine is permanently held in a flexed position. In order to cope with the flexion of the spine and the resulting problems, the sternum must regain its physiological position, which raises the lower costal arch, reduces abdominal pressure, tightens the abdominal wall, and tightens the abdominal muscles Physiological basic tension can absorb and thus better than agonist (opponent) of the back muscles can act. This improves lung function and ventilation of the lower lung. The aim is therefore to mobilize an improved autofunctional spinal column erection (sternal erection).

The technical problem was therefore to provide a device or a device which induces the erection of the spine and enables the mobilization of the vertebrae.

Function of the foam molding

In use, the foam molding with the top (the side having the recess) is placed on the patient's back so that the recess on the top of the foam molding is positioned at right angles to the spine and to the vertebra to be mobilized. The foam molding is pressed against the back. In this case, the foam molding deforms such that the two legs of the foam molding to move toward each other (whereby the volume of the recess is reduced). In the pressing phase, the two mobilization legs of the foam molding approach each other. The spinous processes are taken by the thighs and moved towards each other. This movement to each other causes the tension of the muscles decreases and mobilization of the vertebral joints is facilitated. By compressing the foam molding, the bias of the muscles is reduced. As a result, a direct effect on the to be mobilized vertebral joints (facet joints) is easier to achieve. The vortex is brought by the pressure contact with the radius of the foam molding in an extension position (extension). A short contact is enough to realize a noticeable relief. The press function can be individually dosed.

There are passive and active mobilization options:
In passive mobilization, the foam molding is positioned in supine position on the vortex to be mobilized and the back is placed on the foam molding so that the recess on the upper side of the foam molding runs transversely to the spine. In this position, the patient lingers for a few minutes. It is important to ensure a calm and relaxed breathing. This process is repeated on several spine sections. The aim of this mobilization is a much more relaxed lying. If a relaxed lying is noticeable for the patient, also a better erection (straight standing) is perceptible. This mobilization technique is feasible on various documents z. B. floor, sofa, bed. The patient, who can lie relaxed in this way, can also relax and stand straight.

In active mobilization, the foam molding is positioned between the backrest and back while sitting, so that the recess on the upper side of the foam molding runs transversely to the spinal column. The backrest should have a closed surface and in the optimal case reach to the shoulder. The positioning of the foam molding between the back and back leads to a significantly better erection, without increased muscle activity. The foam molding serves as an erection aid. By slightly increasing the contact pressure, a mobilization of the relevant vertebral segment can be achieved. There may be a slight "click" sound, indicating a release of joint pressure. Reduces joint pressure, a better joint mobility is the result. Increases the joint mobility, so moves a joint much easier. It follows that the spine offers the possibility of a better balance, i. H. vertical alignment, has.

In impulse mobilization, the eddy blockade is released by a short impulse. This mobilization can be carried out, for example, in a door frame or in a car. Thus, the patient stands in a door frame, with the foam molding is positioned between one side of the door frame and the back, and the patient presses with his hands against the other side of the door frame, with slightly bent arms, a contact pressure is performed. When the pulse should be exhaled. This mobilization can also be carried out in the driver's seat in the motor vehicle, since the distance between the steering wheel and upper body results in an optimum arm angle, which is also still individually adjustable. When performing the impulse, pay attention to the lifting of the head and sternum.

Sternal erection

Convex shaped backrests cause a sinking of the sternum and the entire thorax (thorax). Due to the flat contact of the back with the backrest, there is a permanent flexion position, the vertebral joints are in a permanently acting flexion position (bending position). The joint partners of the vertebral joints (facet joints) have less joint surface contact in this position, resulting in an increased joint pressure (pressure load kg / cm ² ). An increased adhesion occurs. High adhesion forces lead to joint blockage and thereby to a restriction or even to a complete loss of movement of the affected joints.

The foam molding eliminates the convexity of the backrest by creating a space between the back and the backrest. The back has the opportunity to stretch. The shoulder blades are released and the shoulder muscles relaxed.

The user experiences by light leaning the impulse of a better erection. The sternum rises clearly, the vertebral joints in this position have a better articular surface contact and the joint pressure (pressure load kg / cm ² ) decreases, whereby the joint blocks are released.

By applying the foam molding of the invention, the sternum comes out of the flexion and takes its physiological position, which raises the lower costal arch and the abdominal pressure is reduced, the abdominal wall tightens, absorb the abdominal muscles their physiological tension and thus better than the agonist of Back muscles can work. This improves lung function and ventilation of the lower lung.

The foam molding according to the invention acts by its pressing function in the form of the approach of the two Mobilisationsschenkel on the tension and thereby enables a direct mobilization of the vertebral joints. Only by reducing muscle tension is it possible to mobilize the vertebral joints. This is required in chiromobilization and also in manual therapy by the therapist with the request "let loose". Because only when the muscles reduce their tension, a direct and, above all, targeted mobilization is possible. The result is an improved joint mobility that allows the vertebral body to take its intended static correct position for him. The spine is thus able to balance itself vertically.

The foam molding according to the invention works directly and precisely on the joint. This is another difference to other mobilization aids.

By using the foam molding according to the invention an immediately noticeable Aufrichtungsverbesserung without an increased muscle activity to demand to achieve.

The foam molding according to the invention will be explained in more detail with reference to FIGS.

In the 1 is the foam molding according to the invention 1 shown in a schematic side view, wherein the foam molding 1 with the top 2 on the spine 14 rests. The individual vertebra are with 9 characterized, with spinous processes 10 and intervertebral discs 12 , With 12.1 , a permanently compressed disc is identified (a facet joint block causes a compression of the intervertebral disc). With 11 is called a blocked vertebral joint. The foam molding 1 has a roughly semicircular or crescent-shaped longitudinal section and has a convex upper side 2 and a concave bottom 3 , Relative to the semicircular longitudinal section are the two corners 4 rounded off the semicircle, leaving the bottom 3 of the foam molding 1 two rounded edges 4 has. The convex top 2 has a transverse recess 5 on. This recess extends continuously from one side surface to the other side surface of the foam molding. At the top 2 of the foam molding stand two legs 6 over the recess 5 across from you. The transverse recess 5 in the top 2 of the foam molding 1 creates a flexibility or hinge function in the central area of the foam molding, between the crest line 7 the bottom of the recess 5 and the crest line 8th the concave underside 3 , This flexibility of the foam molding allows the two opposite legs 6 can move towards each other when between the top 2 and bottom 3 a force is applied to the foam molding.

In the 2 is the operation of the foam molding according to the invention 1 shown. The bottom 3 of the foam molding has two rounded bearing edges 4 that are on a pad 13 support (eg floor, door frame, backrest). The convex top 2 lies on its back so that the longitudinal axis of the recess 5 across the spine 14 runs. This flexibility or the joint function in the central region of the foam molding, between the apex line of the bottom of the recess 5 and the crest line of the concave bottom 3 , allows the movement of the two opposite legs 6 to each other when a force is applied between the top and bottom of the foam molding, the foam molding is thus pressed. The movement of the two thighs 6 to each other (continuous arrows) acts on the spinous processes 10 , The spinous processes and thus the vertebrae are moved towards each other and thereby solved the blockage in the vertebral joint.
