(fan-shaped arrangement) can happen. It is also important let the surface of the hand rest on the base

corresponding to the basal phalanges of the 2nd to 5th finger and the metacarpophalangeal Joint secures, this support rf la'che in the vicinity of the entrance edge of the guide walls forming the channels lies.

According to an expedient embodiment, the Device consisting of a body resting on the inside of the hand, which has ribs on its edge, between which the 2nd lays up to the 5th finger, or has openings near its edge, through which the said fingers reach through, the part of the body adjacent to this edge or these openings the support surface for the basal phalanges and the metacarpophalangeal Joint forms. The width of the ribs or the distance between the holes forces the fingers to make a fan to take a good position.

In another favorable embodiment of the invention the guide walls together with spacers form a frame, whereby between two guide walls in the vicinity of the outer edge the support surface for the basic phalanges and the metaearpophalangeal joint forming parts are arranged.

The device is conveniently attached to exercise the thumb According to the invention, at least one lateral projection is provided against which the thumb for isometric Exercise can create *, or to which a rubber loop can be attached, into which the thumb can reach.

The invention is more expedient in the drawing on the basis of several Aiisf'öhrformen illustrated.

009851/1350

In the drawing, FIG. 1 shows an arthritically deformed hand, the deformation for better clarity because it is slightly exaggerated, "By practicing and strengthening the hand with one of the devices in good time According to the invention, the deformations are to be inhibited in their development, and some are already advanced deforma-. tions should be improved.

FIG. 2 shows the perspective view of a device according to the invention _? in which the guide sw linden are combined with the help of spacers to form a frame which, among other things, supports the support surface for at least one hand.

Figures 3-6 illustrate several types of applications of the object of Figu-r 2, wherein in Figure 4 and 5 in addition Exercise loops made of rubber and their types of application are shown.

Figure 7 this device taken by itself, while the. W Figures 8 and 9 illustrate the device at the same time with the hand to be treated by the device.

Figures 10 and 11 '- finally show in perspective two further embodiments of the invention, »

The embodiment of the invention shown in Figure 2 consists of five guide walls Ij 2 ₉ 3, 4 and 5 $ which have, for example, triangular shape and are united by lower spacers 6 and upper spacers 7 and bolts 8 "9 and 10 g" a frame "that with its underside 11 on a base "for example a table _8" can be placed

can. The five walls 1-5 form 4 guide channels.

up to 5 fingers, while the thumb remains outside the frame.

In FIG. 2, the side of the frame facing the viewer is that side which is used to treat the left hand; the

outside means that the thumb is to the side / the wall 5 and the index finger is inserted into the slot formed between the walls 4 and 5 »the one facing away from the viewer Side of the frame is used to treat the right hand. The spacers provided on the underside of the frame 6, which sit on the bolts 8 and 10, are shorter than the spacers 7, which sit on the bolt 9. The distance between the guide walls thus increases from bottom to top. The significance of this increase will be explained below.

It can also be seen from Figure 2 _? that the spacers 6 and 7, which are located between the walls 4 and 5, are longer than the other spacers, so that the slot intended for the index finger is wider than the slot intended for the other fingers. This has the effect that the index finger can be spread relatively far apart from the neighboring finger, so that the index finger can remain in a straight line with the tendon on its back side during the exercises. This is further supported by the fact that on the side of the wall 4 facing the wall, an insert body 12 is fastened which, for example, can have the cross-section of a segment of a circle and which holds the index finger close to the wall 5.

The ÄuflageriHlehcm for the link © and the right hand are formed by the support structure 13, which is located in the vicinity of the Einjeden of the slots are arranged. The support bodies 15

Exercises of the fingers between the guide walls »For these exercises as well as for others, it is essential that the metacarpophalangeal joints rest on the support surface in a natural position next to one another and that the tendons pass over them in straight lines. An ulnar kink should be avoided in particular for the index finger, which is achieved by .the greater width of the schices intended for the index finger and the insert body 12, which is located in the slot. _:

The correct placement of the hand on the support surfaces is automatic through the position of the support surfaces given with reference to the edges of the guide walls. The patient guides his fingers into the slots between the guide walls so far that the leading edges of the guide walls touch the folds of skin between the fingers.

During the stretching and bending exercises, the guide walls prevent the fingers from bending sideways, which is a problem has a beneficial influence on the interbone muscles (musculi interossei). By placing your fingers sideways against the Guide walls in the sense of an abduction or adduction movement are given isometric exercises, which are also used for strengthening these muscles lead.

As regards Figure 3 specifically, it shows an exercise to strengthen the deep and superficial finger flexors (muscles flexores digitorum profundus et sublimus) of the 2nd to Fingers. This exercise consists in the fact that the cylindrical Support parts are tightly enclosed by the fingers (see ■ Direction of arrows). The basic phalanges remain with this one Exercise stretched so that it is an almost straight line with the

Form a tendon on the back of the hand

At the same time, the thumb can be placed against a pin 22 from below or from above in order to be isometric in this way To carry out exercises.

FIG. 4 shows another exercise for the thumb, which consists in inserting the thumb into a rubber loop 23 which is suspended, for example, on the end 14a of the pin 14 protruding outwardly beyond the wall 5, and the thumb performs the same splaying movements in the rubber loop with extension.

FIG. 5 illustrates an exercise for the finger extensors. There are rubber loops 24 for this exercise • on a lower cross pin 2 5, for example in the holes 16 of the device is stored, suspended and the fingers are passed through the upper ends of these rubber loops, so that they have to overcome the elastic resistance of the rubber loops during the stretching movements. These too Exercise is carried out in a position that corresponds to the normal position of the tendons and muscles "

Figure 6 shows an isometric exercise for the extensor muscles the finger, namely the fingers lie in the extended position against one located in the upper part of the device Pin 26, which is stored in the holes 20 • of the device, for example «

In all exercises, the device can be placed on a surface, for example a table top 27 *

The support surfaces provided on both sides of the device can also be used to practice both hands at the same time. .
