ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a therapy and training device for the shoulder joint with a trunk base having two shoulder extensions on a rotational joint base, respectively associated with a shoulder, rotational around a vertical axis of a rotational shoulder joint means, having respectively spaced apart from the rotational joint base an arm extension for connection with an arm, which is rotationally connected with the shoulder extension around a transverse axis by an upper arm rotational joint means, wherein the shoulder extensions and/or the arm extension are coupled together for movement such that a rotational movement of one shoulder extension, or respectively, of an arm extension causes a rotational movement of the other shoulder extension, or respectively, of the other arm extension.
BACKGROUND OF THE INVENTION
Therapy and training devices utilized for the treatment of movement constraints in an extremity and based on the principle that through the movement of the healthy extremity a movement of the extremity restricted in its mobility is induced, have so far been used for therapy and mobility training of knee joint. Such a therapy and training device is, for example, known from DE 195 09 465 A1. The known therapy and training device serves to treat movement constraints on a knee joint and, due to the substantially single-axis joint form of the knee joint, is relatively simply equipped with only a rotational joint means which connects a lower leg receptacle and an upper leg receptacle as a joint, wherein in therapy operation ideally the rotational axis of the rotational joint means corresponds with the knee joint axis of the patient.
Whereas in practice there is a particularly great need for rehabilitation with regard to movement constraints on the knee joint due to the frequency of knee injuries and associated knee operations, movement constraints on joints, however, generally are always ascertained when a prolonged immobilization of the joint was necessary after a surgical procedure. This also applies in particular with shoulder injuries or surgical procedures on the shoulder which can lead to considerable restrictions in movement in the shoulder region. Based on the complexity of the joint situation in the shoulder area, it is not possible, however, to use the known therapy and training device for a corresponding therapy of a shoulder joint.
SUMMARY OF THE INVENTION
From FR-A-1257 091 a therapy and training device for the shoulder joint is known, having a trunk base, which has on a rotational joint base two shoulder extensions, respectively associated with a shoulder, rotationally coupled by means of a rotational joint means. The shoulder extensions, respectively spaced apart from the rotational joint base, are provided with an arm extension, which is rotationally connected with the shoulder extension around a transverse axis by a upper arm rotational joint means. The arm extensions are coupled in movement such that a rotational movement of an arm extension causes a rotational movement of the other arm extension.
From FR-A-2 789 304 a device is known for the passive mobilization of the upper limbs with different motor means for the prompting of movement drive of a patient's arm.
U.S. Pat. No. 5,613,928 shows a training device with two arm handles coupled in movement for muscle training.
From U.S. Pat. No. 4,971,040 a portable massage chair is known for performing massage therapy in any location.
The object of the present invention is to propose a therapy and training device that enables the performance of a complex movement treatment for the shoulder joint.

In the therapy and training device according to the invention, the rotational joint means is formed as a rotational shoulder joint means such that the shoulder extensions are rotational around a vertical axis of the rotational shoulder joint means and are coupled in movement such that a rotational movement of the one shoulder extension causes a rotational movement of the other shoulder movement.
The configuration of the therapy and training device according to the invention particularly takes into account the shoulder anatomy, leading to the fact that shoulder movements, as a rule, induce arm or at least upper arm movements and vice versa. For example, already a simple forward and backward movement of a shoulder is combined with even a slight rotational movement of the upper arm. Such complex interrelationships of movement require a corresponding joint configuration on the therapy and training device. For the forward and backward movement, thus, the formation of a vertical axis on the therapy and training device is necessary which is arranged preferably adjacent to the shoulder base. In order to enable the overlapping rotational movement of the upper arm with the forward and backward movement, the formation of a rotating axis running correspondingly transverse to the vertical axis is required, which enables a so-called ante- and retro-version of the arm, therefore a forward and backward swinging.
The forward and backward movement of the shoulder blade with the overlapping forward and backward movement of the arm is enabled by the shoulder extension, formed as a joint lever, enabling a connection between the shoulder rotational joint means and the upper arm rotational joint means, thus, between the vertical axis and the transverse axis. To transmit the rotational movement executed on one side of the body by the shoulder blade or the arm or both to the other side of the body, the shoulder extension respectively associated with the other side of the body, or respectively, the arm extension associated with the other side of the body is respectively coupled in movement with its corresponding counterpart.
Particularly for the repositioning of the therapy and training device relative to the upper body of the patient, it is advantageous when a positioning means for the relative positioning vis-a-vis the spinal column of the patient is associated with the rotational joint base. Through this, it is possible to position the therapy and training device to the upper body of the patient without requiring an adjustment of the joint configuration of the therapy and training device to the individual anatomy of the patient even after an interruption of therapy and for the resumption of therapy.
A particularly direct manner of positioning results when the positioning means has a neck receptacle, adjustable in height, arranged on the rotational joint base along the trunk base. The neck receptacle, furthermore, also provides a possibility to prevent voluntary or involuntary avoidance movements of the upper body during the operation of the therapy and training device which could negatively affect, in particular, the desired adjustment of the joint configuration of the to therapy and training device to the individual anatomy of the patient. In principle, of course, other correspondingly effective means can be provided.
When the arm extension on the therapy and training device comprises an upper arm extension and a lower arm extension, wherein the upper arm extension is connected to the shoulder extension via the upper arm rotational joint means and the lower arm extension via an elbow joint means comprising at least a rotational axis is connected to the upper arm extension, it is possible to also integrate lower arm movements. For this purpose, relative movements in the simplest form of the lower arm compared to the upper area are sufficient, without having to transmit the movements of the lower arm extension like the movements of the upper arm extension and of the shoulder extension on the other side of the body in movement-coupled manner. Since relative movements of the lower arm can often be performed without restrictions compared to the upper arm with a shoulder restricted in movement, a corresponding coupling of the movement of the lower arm extensions of both sides can be omitted. Since, on the other hand, ho
