DESCRIPTION:
BRIEF SUMMARY
The invention relates to a couch of adjustable inclination, especially for body extension in a head-down position, having a couch carrier and a support table securable to the carrier in different inclinations and provided with a foot or lower-leg retaining device and a head rest.
The stretching of body joints, especially of the spinal column, is an important therapeutic measure in connection with the therapy of rheumatic ailments, muscular strains, posture damage or the like. In healthy persons body stretching can contribute to an increase of well-being, especially to the promotion of relaxation. Horizontal stretching tables are known on which the body is stretched by the drawing slightly apart of a foot loop and a head loop by means of an appropriate mechanism. It is disadvantageous here that the body is subject to the applied traction force over its entire length between the fastening points, so that by way of example the cervical vertebrae are subject to the same traction stress as the two knee joints together. However it is frequently desired to load a part of the joints, at least at the beginning of therapy, to a reduced extent or not at all. This is valid especially in the case of muscle strains and spinal column torsions. Too great an extension of the joints associated with the muscular strain, especially the corresponding vertebrae, would lead to a reflextype increase of the muscular strain.
With the couches of adjustable inclination of the kind as initially mentioned, the traction force in the head-down position naturally decreases from the feet to the head, since the remaining body length to be carried by the joint concerned decreases towards the head. In order, especially in the case of neck nape stresses, to relieve the vertebrae in the neck region at least initially, a head rest is provided on which the head is supported. While in the known couches of adjustable inclination the head rest can be made fast to the support table in different positions, for adjustment to different body sizes, there is however no possibility of altering the head rest position or the retaining device position during the traction treatment, that is with the couch occupied in the headdown position. However the joint and muscle extensions occurring as desired during the traction treatment result in an increase of the body size by up to 1-2 cm. With an unchanged body support length between retaining device and head-rest this leads to an "upsetting" of the body in the neck nape region, that is to a complete elimination of the desired tensions present here and to the build-up of compression stresses, with corresponding deviation of the spinal column by slight S-shaped curvature.
The problem of the invention consists in preparing a couch of adjustable inclination for body extension which permits the setting and maintenance of a desired extension condition during the traction treatment, independently of the body elongation.
This problem is solved in that the body support length between the retaining device and the head-rest is adjustable continuously or by fine stages according to the increasing body extension, with the table occupied in the head-down position With increasing body elongation the body support length is correspondingly adjusted, so that constant tension conditions result.
On the known horizontal traction table and the known couch of adjustable inclination the couch support surface, apart from cushioning, is substantially flat. In the case of muscle strains, spinal column torsions, rheumatic ailments or the like the body assumes what is called a protective posture in which pains are least perceived. Frequently the protective posture consists in an angling off of the knee joints and of the thich-pelvis joints. Such bending also corresponds to a relaxation position in the healthy person (posture of the unborn child in the womb). If in traction treatment one starts from such a protective or relaxation position, the danger of the occurrence of additional strains or even injuries (joint injuries, muscle micro-tearin
