Definitions

  • This invention relates to a device for effecting stretching of the vertebral column, in particular of the dorsal and lumbar vertebrae, treatment of the muscles, gymnastics and relaxation of the body.
  • Known such devices generally comprise a table, on which the patient is placed, and two harnesses, connected with the. movable parts of a stretching mechanism, one of which is secured under the patients arms and the other to his pelvis, an operator actuating the stretching mechanism until the desired effect is obtained.
  • a stretching mechanism one of which is secured under the patients arms and the other to his pelvis, an operator actuating the stretching mechanism until the desired effect is obtained.
  • the patient undergoes a stretching determined arbitrarily by the operator and he is not able in any way directly tostop this stretching if it is excessive which, in particular when the stretching device is a hydraulicdevice of substantial damage.
  • LEl-IMAN and BRUNNER haveestablished that, on young subjects, after 5 minutes traction at 135 daN they obtained on average a spacing of 1.5 mm from the fifth to the sixth lumbar vertebrae and 1.3 mm from the third to the fourth lumbar vertebrae, and that the return to the normal spacing takes place within minutes.
  • the device according to the invention is characterized in that it comprises a separating wedge including, on the one hand, gripping means which the patient may hold with each of his hands his arms being extended parallel to the extension of his chest and, on the other hand, counter-bracing means spaced by such a distance from the aforesaid gripping means that the patient may place them in the angle that his thighs, bent approximately at right angles under his chest, form with the latter and that his arms always remaining extended in the extension of his chest he may, by decreasing the angle subtended by his thighs and chest around the said counterbracing means, stretch his vertebral column between his pelvis and his shoulders by a lever action of his thighs on the counter-bracing means. 7
  • Such a device may be used as a gymnastic device without any support relative to the ground.
  • It may be constituted by a simple rigid and lightweight frame, two opposing sides of which serve, one as the gripping means in the form of a transverse bar which the patient may grip with-his hands and the other as a counter-bracing means for his thighs.
  • These counter-bracing means are advantageously arranged so as to provide a substantial surface, preferably rounded and padded, uniformly shaped to follow approximately the shape of the thighs which press against them. They may be mounted to pivot between the adjacent sides of the frame formed by the device, and in particular may be constituted by a roller which pivots between these sides.
  • the distance between the gripping means and the counter-bracing means is very important, it is appropriate to make it so that it can be accurately adjusted. Moreover, this adjustment is necessary if it is desired that people of different heights may use the same device. In the majority of cases, it is sufficient to have an adjustment ranging from a minimum distance of I00 cm to a maximum distance of 150 cm.
  • the device is constituted by a frame, it is convenient to make the sides of it telescopically adjustable in length and to provide means for locking the inner telescopic member in the outer member of each of the sides, for example by tighteningscrews, screwed into the outer member.
  • a table with the device, whilst mounting between the outer members of the telescopic sides a rigid panel provided with feet and on which the patient may lean relative to the ground.
  • feet adjustable in height, for example by making them telescopically extensible and by providing them with locking means which may be of any type generally used for this purpose.
  • the table may be used for other uses in the home, in particular as a tea table, bar table side table and preferably as an all-purpose table for a bed-ridden person.
  • the table for this purpose, it is appropriate for the table to comprise a base with at least one leg open laterally and the lower part of which, which rests on the ground, may be slid laterally under a bed, the upper panel or plate of the table being adjustable in height and in inclination on this base.
  • this additional, detachable upright of the table panel pivots about a horizontal shaft in the lower part of the base which comprises means for securing the upright in a substantially horizontal retracted position within the overall dimension of this lower part.
  • the device comprises, between the gripping and counter-bracing means respectively, a telescopic rod for adjusting the distance and provided with a locking means.
  • the latter is advantageously constituted by a ratchet wheel operated by a crank which may be freely rotated in the direction-which increases the distance between the means in question.
  • a dynamometric indicator with a small control stroke and which, preferably, is of the type indicating the maximum compression reached during the elongation operations.
  • FIG. 1 shows diagrammatically and in perspective a device for vertebral stretching constructed according to the invention
  • FIGS. 2 and 3 show diagrammatically two extreme positions for use of this device
  • FIGS. 4, 5 and 6 are diagrams of the kinematics common to various types of devices constructed according to the invention.
  • FIG. 7 shows diagrammatically and in exploded perspective another embodiment of the device
  • FIG. 8 shows in section and on a larger scale a detail of the device of FIG. 7;
  • FIG. 9 shows diagrammatically and in elevation the manner according to the invention of using the device shown in FIG. 7;
  • FIGS. 10 and 11 show devices constructed according to two other variations according to the invention.
  • the device according to the invention is constituted by a frame, the two opposite sides of which provide the gripping means, namely a transverse bar 1, and the counter-bracing means for the thighs of the patient, which means is constituted by a roller 2 or any other suitably rounded or uniformly shaped member provided, if necessary, with appropriate padding.
  • the two other sides of the frame are arranged so that their length can be adjusted between 100 cm and 150 cm.
  • the latter sides are constituted by telescopic rods, the internal members 3 of which are integral with the bar 1 and the outer members 4 are secured to the shaft or pivots of the roller 2.
  • the adjustment of the distance between the bar 1 and the roller 2 is effected by a greater or lesser telescopic elongation (under the circumstances between 100 cm and 150 cm) of the rods 3 and 4, the internal members 3 of which may be locked in position in the outer members 4 by locking screws 5.
  • C which is the distance between a and b is a fixed lengthzthat predetermined by the device.
  • a which is the distance between b and 0 may also be considered as a fixed length whereas B which is the distance separating the users hands from the pivot of the femur on the pelvis is a length which, between the positions shown in FIGS. 2 and 3, must be able to be slightly extended, which causes the desired corresponding elongation of the vertebral column.
  • the maximum useful angle a through which the user may theoretically bend his thighs relative to the chest about the roller 2, is 90, since it is naturally necessary that he starts from a position in which the roller remains locked against the upper part ofhis thighs.
  • the extension obtained over the last 10 of bending corresponds to approximately only 6 percent of that obtained over the first 10 envisaged or even that a user, capable of developing a force of IO daN over the first 10 of movement, if by an accurate adjustment he was led to effect the same force over the same distance corresponding to the last 10 would exert, due to reduction, a force I 7 times greater, i.e. 170 daN.
  • the result is the advantage that there exists in adapting the length ofthe device to the exact height of the user.
  • the device in the form shown in FIG. 1 is quite suitable for certain uses, in particular as a device for gymnastics, physical exercises and kinesitherapy, it is preferable, for patients for vertebral re-education and suffering with lumbage, sciatica, back trouble, slipped discs, rheumatism, dorsal troubles, arthrosis etc, to include with the device a table, supported relative to the ground at the desired height, on which the patient may rest in a stable manner with the upper part of his body.
  • the table can be adjusted in height, so that it can be accurately adapted to the height of the pa- Elem.
  • the desired stretching force is thus obtained by bringing the knees up under the table.
  • the table is adjusted to a height such that the user may bend his knees under the latter, when his heels rest on the ground, The user obtains the desired stretching by raising his heels and by pushing his knees forwards and upwards, whilst keeping the front ofhis feet on the ground.
  • At least one telescopic leg which may be locked in position by any known suitable system.
  • the table advantageously arranged in such a way that it can serve for other uses, namely as an all-purpose table for a bedridden person. It comprises a leg structure 9 with feet which structure opens laterally and the lower part of which, which rests on the ground, may be slid laterally under a bed.
  • the leg structure comprises on the opposite side to the telescopic leg 9 of the base, at least one additional telescopic leg 10, the inner part 11 of which, can be locked by a locking screw 12 screwed into the outer part 10, and is threaded at the end in order to be able to be screwed into a tapped sleeve 13 fixed under the panel 6 of the table.
  • the outer part of the additional leg is. mounted to pivot about a horizontal shaft 14 in the base of the leg structure, an opposing cross-piece 15 of which has another tapped sleeve 16 into which there may be screwed the end of the inner part 11 of the telescopic leg in the position shown in dot-dash lines in FIG. 7, in which this leg is retracted within the overall dimensions of the lower part of the base.
  • the shaft 14 and the cross-piece 15 may constitute the only struts of the base and may be secured in a detachable manner by their two ends into tapped sleeves with opposite threads and integral with the side-pieces 9a" of the base. If it is desired, in manner known per se, that the base can be removed from the so-called table, it can bedismantled as will the realized on examining FIG. 7, into four parts, i.e. two members 9 9a, a part 15 and a part 10, ll, 12, 14 which are all flat and, consequently lend themselves to a very compact stowage arrangement when the table is not in use.
  • FIG. 10 there is provided for adjusting the distance between a bar 1b and a curved member 8a, a rod 17 integral with the bar 1b and which can be locked in position telescopically, in a guide member provided under the panel 60 of the table, by means of a locking bolt which makes it possible to pull the bar lb while separating it from the panel 6a but prevents it from returning without interfering with an unlocking member.
  • the rod 17 is constituted by a rack which cooperates with a pinion 18 integral with a shaft 19 which rotates under the table in bearings 20 and 20a, co-operates with a ratchet wheel 21 and terminates on the side of the table in a crank 22.
  • a dynamometer 23 which is preferably of the type indicating the maximum compression reached and the needle of which, after each measurement has to be returned manually to the zero position.
  • a totalisator indicating the total of tractions carried out.
  • FIG. 11 shows a table 6b constructed according to another embodiment and on which the gripping means provided to be gripped by the user are constituted by separate hand-grips 24, fixed vertically in the table in a series of holes 25 located at variable distances from the curved member 8b.
