DESCRIPTION:
BRIEF SUMMARY
The invention relates to a shoulder bandage according to the part of claim 1 describing the state of the art.
To date, such bandages were used primarily in collar bone fractures, and are known e.g. from U.S. Pat. Nos. 3,856,004 and 3,857,388. They force the wearer to assume a straight posture, his mobility being extremely limited because of the pull bands being only slightly stretchable in the manner of backpack-carrying straps and usually arranged very near the neck area.
In this context the shoulder belt according to U.S. Pat. No. 3,548,818 is of only little help because of the large-area back part, as well as the pull bands, can be stretched essentially only in the longitudinal direction, and hence affect only a limited number of movements or degrees of freedom of the wearer.
For example, an elastic vest with support collar which can be used for therapeutic purposes has also become known from CH-A-641344. In this case, however, the principal objective is the support in the cervical region, or the effect of heat in the shoulder joint. In contrast to the aforementioned "static" collarbone bandages, and also to the forementioned shoulder belt, the invention proceeds from quite different problematics that are to be met by the aid of a shoulder bandage with "dynamic" action on all sides. Namely, to date a shoulder bandage which has gladly been worn, and which still achieved its intended effect, did not exist.
The progress of civilization has led to a highly developed, predominately sitting human being who has becomed accustomed to sitting in a crooked position, because of which the thoracic girdle, especially the acromio-clavicular joint is overstressed. The spinal column as the supporting member of the body is used only partially, while other parts of the trunk, which were oridinally intended for other functions, such as the breastbone, must take over functions as supporting and holding functions of the truck. Since in the relaxed sitting position ("sternal tensioning posture") the breast kyphosis is intensified and the lumbar lordosis is cancelled, both spinal column sections form a uniform kyphotic arc; in contrast to the position of the thorax when standing and walking, the sternal joints are overstressed.
During sitting the axial weight on the spinal column is converted into flexure; the center of gravity line is displaced ventrally, and the weight of the head and the thoracic girdle and the arms is transmitted predominately to the breastbone--which is not without its effects on the position of the cervical vertebral column and on the joints of the thoracic girdle which are thereby irritated. The musuclature is reflex-tensioned and pain signals are sent to the spinal marrow and the brain stem, which transform the signal of the incorrect stressing of the breastbone joints into an orderly and effective musculatory resistance intended to relieve for releiving the tension of the aching joints. The corresponding muscles are innervated (e.g. musculus sternocleidomastoideus, musculi scaleni, extensor of the back), which can lead to an overstressing of this musculature, and consequently to extensive pains in the entire region of the thoracic spine up to the back part of the head.
In the treatment of persistent cervical syndrome, shoulder-arm syndrom and thoracal syndrome these mechanisms must also be taken into account. They are the result of secondary side effects of a nociceptive somatomotoric blocking effect having its origin in the pain sensors (nociceptors) of the affected articular capsules, tendom attachments, of the periosteum and other tissues. It is the expression of reflectory mechanisms that are available to the organism to spare the irritated tissue.
Based on these findings the invention has as its objective the improvement of the supporting action in the shoulder region and the counteraction of the sternal stressing posture by a continuous and adjustable pull in the area of the shoulder belt. This is accomplished by the shoulder joint bandage according to the present invention developed after thor
