Definitions
- the present invention relates to a therapy and training device for positively guided knee joint movement with a lower leg receiving arrangement and a guide arrangement which are pivotally connected to one another via a joint device.
- Knee injuries and related knee operations often require long-term immobilization of the knee joint, which leads to a general weakening of the leg muscles and to restricted movement.
- Appropriate medical aids are therefore used in the treatment of knee injuries or after knee operations, which are intended to reverse movement restrictions or to counteract the development of movement restrictions by carrying out certain movement exercises.
- motor splints are used for joint rehabilitation.
- the motor rails serve to receive the diseased leg and are provided with a drive device which enables pivoting of a lower leg holder relative to a thigh holder. This results in a knee joint movement that is essentially free of weight loads, so that the mobility of the knee joint is trained without weight loads that are harmful to the cruciate ligaments.
- It is perceived as a disadvantage of the known motor rail that, on the one hand, a generally electric drive is required to move the motor rail, and on the other hand that the healthy leg is excluded from the movement, so that especially in the case of longer
- the present invention is therefore based on the object of proposing a device which, like a motor rail, enables a kinematically clear, positively guided flexion movement of a knee joint without the disadvantages described above being associated therewith.
- the guide arrangement cooperates with the lower leg mounting arrangement in such a way that when a lower leg is pivoted, it results The other lower leg is forced to move.
- the drive for the force-relieved movement of the sick leg is carried out by a force-operated movement of the healthy leg, so that on the one hand there is no need for an external drive, and on the other hand there is also a certain amount on the healthy leg Training effect for strengthening the leg muscles, both the movement of the sick and the movement of the healthy leg being an effective thrombosis prophylaxis.
- lower leg mounting arrangement used here is also intended to include the possibility of fixing the lower leg to a rail-like device, for example lying on the outside. What is essential is a defined fixing of the lower leg, which enables the movement sequence described above.
- the guide arrangement is designed as a thigh receptacle and the lower leg receptacle is used for motion-coupled receptacle in the lower leg, in such a way that the other lower leg is positively moved when the one lower leg is pivoted due to knee flexion.
- a force-relieved movement of the sick leg can accordingly be achieved by a force-operated movement of the healthy leg. Via the movement coupling between the healthy and the sick leg, the sick leg is carried along with the movement of the healthy leg.
- the therapy and training device can also be used as a pure training or sports device for training the leg muscles on both legs.
- the joint device is arranged so that its axis of rotation lies coaxially with the pivot axis of the knee joints, it is ensured that the knee joints are free of moments and transverse forces that would occur when the axis of rotation was offset from the pivot axis .
- the lower leg receptacle is provided with a slide or roller guide in a heel area, so that it is possible to move the lower leg receptacle over a correspondingly designed base when the knee is moved.
- This training makes it possible to use the therapy and training device with the patient in a lying position, in which the patient's buttocks and heels are essentially in one plane and the movement of the sick leg by angling the healthy one Leg is reached.
- the therapy and training device can thus be used in the bed of a patient, in particular when using a roller guide that places less stringent demands on the levelest possible formation of the subsurface.
- the joint device of the therapy and training device can be provided with two variable angle stops in order to set a specific knee flexion range, which proves to be particularly advantageous for the therapy of the sick leg.
- the joint device is provided with a locking device for variable adjustment of a fixed knee bending position. This makes it possible to lock the joint device in a knee flexion position that is comfortable for the respective patient and thus to define a rest position in which the patient can stay for a long time without any uncomfortable tension without the therapy and training device should be removed beforehand and reinstalled when resuming exercise therapy.
- This proves to be particularly important, since such therapies are often carried out in a so-called interval form with more or less large pauses in movement between the movement sections.
- the joint device is provided with a movement counter, which can be designed, for example, as an inductive rotation angle sensor, a particularly simple possibility is created for monitoring the movement training carried out with the therapy and training device.
- a load device which is designed in a particularly advantageous manner as a spring device, can be arranged between the thigh receptacle and the lower leg receptacle.
- the spring device By simply changing the spring preload, the spring device enables a precise specification of the load on the healthy leg during movement training of the sick leg.
- the spring device can be designed as a cable tension spring, that is to say as a flexible cable.
- a compression spring can be provided.
- the therapy or training effect can be further improved if, in addition to the load device, which is particularly advantageously designed as a spring device, a damper device between the thigh receptacle and the lower leg receptacle are provided with an effect. This makes it possible to carry out a movement that is uniform with respect to the speed of movement, that is to say isokinetic.
- the lower leg receptacle can be provided with at least one guide which can be changed relative to the lower leg receptacle. This makes superimposed movements of the lower legs possible when the knee is bent, so that the lower legs can be moved not only in a swivel plane but also transversely thereto.
- Both the lower leg receptacle and the thigh receptacle can be cup-shaped, for example made of plastic, with guides for the length-adjustable receptacle of swivel arms connected to the joint device. It is particularly advantageous if the guides are integrally formed in the lower leg receptacle and the thigh receptacle. This reduces the number of parts of the therapy and training device. On the other hand, the assembly effort when assembling the therapy and training device is reduced accordingly.
- the joint device is designed in such a way that two swivel joints are provided in the outer knee area, on each of which two swivel arms are arranged for connection to the upper leg holder or lower leg holder, a particularly torsional enables the rigid construction of the therapy and training device.
- a thigh fixation provided for fixing the thighs to the thigh receptacle is designed such that it can be used alternately for both thighs. The same applies to lower leg fixation.
- At least one spring pivot point can be designed to be changeable.
- the embodiment according to claim 22 has a guide arrangement which is designed as a pivot axis of a pivot arrangement.
- the relative arrangement of the swivel axis can be changed with respect to the hip pivot point of a patient.
- Lower leg receptacles are articulated on the swivel joint arrangement and are coupled in such a way that a pivoting movement of one lower leg receptacle about the pivot joint axis causes an oppositely directed pivoting movement of the other lower leg receptacle.
- the pivoting movement takes place in a forcibly guided manner about the axis of rotation of the rotary joint arrangement, so that directions of force harmful to the knee joint are excluded.
- the changeability of the spatial arrangement of the swivel axis relative to the hip joint pivot point of a patient allows a congruent setting of the swivel axis and thus isometric conditions with the knee pivot points. This also helps to keep harmful loads away from the knee joint, such as occur, for example, when the femur is advanced axially through the tibia (known as the "drawer effect").
- a flexing movement of the healthy leg can be used for a corresponding bending movement of the sick leg, without the need for a complex drive would.
- the frequency of the knee flexions from the patient to a suspension of the swiveling movement itself can also be influenced at any time by the movement coupling described above, so that the device itself can be started up by the patient at any time.
- nursing staff be used to monitor the operation of the device, since the patient himself can easily manipulate it at any time. Due to the lack of a drive device or the simple operation of the device, this also proves to be considerably cheaper in terms of acquisition or operating costs.
- the device enables active exercise with a natural, physiological movement sequence.
- the reciprocal initiation of movement through the coupling of movements promotes cartilage and tendon formation.
- the device can be used without any changes both as a passive movement device and as an active training device, so that, for example, as rehabilitation of the knee joint progresses seamlessly to one
- Exercise can be changed by active movement of the knee joint.
- the pivoting movement takes place in a pivoting region which has a central position in which the lower leg receptacles have an identical pivoting position.
- This enables the patient using the device to assume a particularly comfortable rest position in the middle position, in which the lower legs are at the same height. It is also possible to leave the device on the patient between successive treatment sequences without this being associated with inconveniences for the patient. On the contrary, an elevated leg position is often perceived as pleasant by the patient.
