Description

DESCRIPTION

The invention relates to a training device used in medical therapy and rehabilitation to strengthen the muscles and / or to train the sensorimotor system is used by patients.

Known training devices of this type have arm levers and foot levers that from the patient overcoming some resistance with the ar men or legs or operated by a motor or the like Chen driven to passively be the patient's extremities because of. In some cases, it can be helpful for the patient if he can control the passive movement of a damaged limb itself, for example by moving the right arm through the passive Right leg movement controls or vice versa.

From WO 97/06859 A1 is a training device according to the preamble of the An saying 1 known, in which the arm and arm belonging to the same side of the body Foot levers can be mechanically coupled to one another.

The object of the invention is to provide a training device with which Train more complex movements and thus additional therapeutic let achieve effects.

This task is there with a training device of the type mentioned above solved by that each arm lever has a swiveling hand-support plate and each foot lever has a pivotable foot plate and that the Pivotal movement of each arm support plate relative to the arm lever with the Swiveling movement of the associated footrest plate relative to the foot lever can be coupled.

With this device the user can not only by active arm movement ne passive leg movement, but it can also by Angling the wrist is a corresponding movement of the ankle cause. In this way, movement coordination in particular be trained effectively in more complex movements. As well the device is suitable for training the hand and foot movements responsible forearm and lower leg muscles. For example  the patient exercising the forearm muscles by holding the Angled hand support surface while doing a metered counter with the foot exerts pressure.

Advantageous refinements and developments of the invention result itself from the subclaims.

The coupling between the different support plates can be mechani paths, for example through rods or cables, or on electronically with the help of motion sensors, motors and one suitable control electronics. It is also possible to change the ak to resist the patient's movements by the movements of the support plates and / or the arm and foot levers with do force are braked or by these movements an elastic restoring force or a weight force is opposed. If for the arm and foot levers and / or the support plates are motor drives seen, passive exercise therapy can also be performed the, with a total of eight degrees of freedom of the arm, leg, hand and Foot movements coupled with each other in a program-controlled manner in a flexible manner can be.

According to a development of the invention, each hand support plate has at least one swiveling finger lever and each footrest plate at least one swiveling toe lever, and also the swiveling movements of the finger and toe levers are coupled with each other. The Coupling can be used for all fingers of the hand and all toes of the corresponding foot together or for each pair of fingers and toes ge separately or in groups, for example for thumbs and big toe on the one hand and the remaining fingers and the other toes on the other on the other hand.

The position of the swivel axes for the arm and foot levers and the various NEN platen is preferably adjustable so that the device to the Kör permasse different patients can be adjusted.

Preferred exemplary embodiments of the invention are described below the drawing explained in more detail.  

Show it:

Fig. 1 is a schematic side view of the training device according to the invention; and

Fig. 2 is an enlarged view of an arm lever with a hand support plate according to another embodiment.

The training device shown in FIG. 1 has a vertical column 12 arranged in front of a bench 10 , on which a joint 14 for two arm levers 16 , 18 and a joint 20 for two foot levers 22 , 24 are held in a height-adjustable manner. The two arm levers 16 , 18 are individually rotatable about a common horizontal axis passing through the joint 14 . The same applies to the two foot levers 22 , 24 .

Each arm lever 16 , 18 and each foot lever 22 , 24 has a joint 26 near its free end, on which in the case of the arm levers 16 , 18 a hand support plate 28 and in the case of the foot levers 22 , 24 a foot support plate 30 is pivotally attached. The swivel axes of the support plates also run horizontally.

The patient sitting on the bench 10 places both hands on the hand support plates 28 and both feet on the foot support plates 30 in order to move the arm levers 16 , 18 and / or by active movement of the legs by active movement of the arms To turn foot levers 20 , 22 .

The arm lever 16 for the patient's right arm and the foot lever 22 for the patient's right leg are connected by a rod 32 which extends between the joints 26 . In this way, the movements of the right arm and foot levers are mechanically linked. In a corresponding manner, the movements of the arm lever 18 for the lin ken arm and the foot lever 24 for the patient's left leg are coupled to one another by a rod 32 . Furthermore, the hand and foot rest plates 28 , 30 for each side of the body are coupled by a rod 34 . Optionally, the movements of the arm and foot levers 16 , 22 for the right side of the body can be coupled to the movements of the arm and foot levers 18 , 24 for the left side of the body at the joints 14 , 20 , the phase difference between these movements not being the same as in FIG shown example must be 180 °, but can assume any angle between 0 and 360 °.

If, for example, the patient cannot actively move one leg or both legs as a result of a stroke or a spinal cord lesion, the patient actuates the arm levers 16 , 18 with the arms, so that the foot levers 22 , 24 also move due to the coupling, and thus the Perform a passive movement on the patient's legs. In addition, the patient can pivot the hand support plates 28 by moving the wrists, so that due to the coupling by the rods 34 , the foot support plates 30 and thus the patient's feet are pivoted accordingly.

Accordingly, if the arms are unable to move, passive movement can be arms and hands using the patient's legs and feet be controlled.

The hands and feet of the patient are preferably strapped to the corresponding support plates, so that the patient can also lift these support plates. By adjusting the height of the joints 14 , 20 , an adaptation of the device to the patient's anatomy is made possible. Likewise, the positions of the joints 26 can also be adjustable in the longitudinal direction of the arm and foot levers concerned.

Fig. 2 shows the arm lever 18 with the associated hand support plate 28 according to a modified embodiment.

The hand-support plate 28 is formed here by a plurality of parallel slats 36 , which are all pivotable about the common joint 26 and lie one behind the other in FIG. 1 in the direction perpendicular to the plane of the drawing. In the area of the free ends, the lamellae 26 are connected to one another by two bolts 38 . Furthermore, the hand support plate comprises four or five auxiliary slats 40 , which engage in a comb-like manner between the slats 36 . Each auxiliary lamella 40 has at the free end a joint 42 on which a finger lever 44 is pivotally attached. The user pushes his fingers under a bracket 46 of the associated finger lever 44 so that he can move the finger lever with the fingers up and down individually.

In this embodiment, the footrest plates, not shown, have the same basic structure as the handrest plate 28 . Each fin lever 44 is coupled via a rod 48 to a corresponding toe lever of the footplate. The patient can thus individually control the movement of his toes with the fingers.

The auxiliary slats 40 each have an elongated hole 50 penetrated by the bolts 38 and are thereby held individually adjustable on the slats 36 . In this way, the position of the joints 42 can be adapted to the position of the corresponding first finger joints. In addition, the auxiliary slats 40 are adjustable in the longitudinal direction of the bolt 38 , so that the stands between the auxiliary slats and thus the distances between the finger levers 44 can be adjusted to the width of the patient's hand. The finger levers can also be angled or bent laterally in order to adapt to the spreading of the fingers of the hand.

In the example shown, the finger levers 44 can be pivoted about horizontal axes. Optionally, however, a thumb lever (not shown) can be provided instead of the fifth finger lever, which can be pivoted about an oblique axis according to the anatomy of the human hand.
