Description

The invention relates to a device for training the lower and / or upper extremities of a person according to the preamble of claim 1, the use of such a device according to the preamble of claim 13 and method for controlling and adjusting such a device according to the preambles of claims 14 and 15. Such a device may also be referred to as a training device for training a person's motor skills. It is particularly suitable for training the upper extremities, ie the arms, and / or the lower extremities, ie the legs, of a person.

Numerous training devices for the upper and lower extremities are known in the prior art. For example, there are mobile training equipment that can be placed on the ground with a base element on which two pedals with pedal arms are mounted as actuators. These pedals can then be operated by a user like riding a bicycle. Optionally, in such devices, the pedals can be exchanged for handles with a crank, so that the device can be operated as a so-called hand bike when it is on a table.

Also known are devices that have two pedals with pedal arms and two handles. A user can simultaneously exercise the upper and lower extremities with such devices by operating the pedals as seated or standing as with a bicycle and simultaneously operating the handgrips as with a handbike.

Furthermore, there are training devices that can be operated by a user lying in a bed. For this purpose, such a device on a mobile frame with a boom, which then extends over the bed. At the free end of the boom two pedals with pedal arms are mounted, which are operated by the user as when riding a bicycle. It can be replaced in such devices again the pedals against handles with crank, so that the device can be operated as a hand bike. The common axis of rotation of the pedals or the handles can be advantageously moved relative to the boom about an axis perpendicular to the axis of rotation, so that the frame with the boom of different sides of the bed can be pushed to the lying user without the user having to change his position.

In each of these devices, the left and right pedals and the left and right handles respectively rotate about the same axis and are mechanically coupled, that is, both pedals or handles always move together.

Are known from the US 3,711,089 A also ski training equipment, where the skis run on front and rear wheels. Optionally, the front and rear rollers are driven in opposite directions so that the skis are alternately moved forwards and backwards as the user moves their weight. Furthermore, two drives can be provided, one for rollers for the right ski and one for rollers for the left ski, so that the left and right rollers and thus the left and right skis can have different speeds of rotation. The geometric arrangement of the rollers is not changeable.

The DE 299 22 913 U1 discloses a training device, in particular for the physically disabled, with a stationary or movable frame and a variable height by means of a drive lifting member on which a support means is arranged for the person to be trained. By raising and lowering the lifting member, the person can be brought, for example, from a sitting to a standing position and vice versa. If the frame is bridge-shaped, two drives are preferably used, which are arranged in the two frame posts or in the two end regions of the frame carrier or the lifting member.

The DE 103 16 688 A1 describes a training device with at least two movable relative to a device frame footprints for each foot of a user and with a motor drive for generating a rolling or pivoting movement of the support surfaces relative to each other.

Is known from the WO 2006/069988 A1 a bicycle vibration ergometer with a frame having a seat unit, a bottom bracket and crank unit and a vibration unit, wherein the vibration unit is connected to the bottom bracket / crank unit and the bottom bracket / crank unit of the seat unit is mechanically decoupled.

The WO 2016/032416 A1 discloses a movement exerciser to train the walking motion of a user. The user is held by slings to the lower extremities to relieve. The legs are guided while walking, so that even a purely passive user can perform a walking motion.

The EP 2 010 121 B1 relates to an exercising apparatus for a person's musculoskeletal system, comprising a rocker pivotal rocker supporting the person, and a drive assembly having at least one engine and transmission elements, the transmission elements forming at least one power transmission chain between the rocker and the engine.

On the basis of this prior art, the object is to provide a training device for training the motor skills of a person, which has more flexible adjustment options than the training devices known from the prior art. The flexibility may relate, for example, to the geometry of the device and / or to the operation of the device, so as to enable optimal adaptation to each user and to each training purpose.

This object is achieved by a device for training the lower and / or upper extremities of a person, which comprises the following features.

First, the device has at least two movement elements, which are arranged on a base element. The movement elements each have an axis of rotation about which an actuating element can be moved. The device is characterized according to the invention in that the movement elements are each independently movable relative to the base member about a first axis of movement. In this case, the first movement axis extends substantially perpendicular to a surface in which the basic element extends.

By an independent movement of the movement elements relative to the base element, it is possible to adapt the orientation of the movement elements individually to a user and thus to achieve the optimum setting of the invention claimed device for the user.

The term "essentially" indicates an angle range of plus minus 5 ° around the specified geometric relationship. "Substantially perpendicular" thus refers to an angular range of 85 ° to 95 ° and includes "vertical" (90 °) with a. "Substantially parallel" thus indicates an angular range of -5 ° (355 °) to + 5 ° (5 °) and includes "parallel" (0 °).

The individual movement elements can be designed identical, but they do not have to be.

In a variant, at least one of the moving elements, in particular each of the moving elements, a drive in order to rotate the actuating element about the axis of rotation. Without such a drive, the invention can be used according to the claimed device for actively exercising the lower and / or upper extremities of a person. However, if at least one drive is provided, it becomes possible to train even a purely passive user or to allow support of the movement of an active user. The latter is also referred to as a servo drive.

In one variant, all motion elements having a drive have their own drive. The particular effect of such an embodiment is that left and right as well as upper and lower extremities can be addressed flexibly and differently, for example if differences in the motor skills of the left and right or upper and lower extremities of the user are present.

In a variant, at least one of the moving elements, in particular each of the moving elements, has a means for detecting a movement which is applied to the actuating element by a person using the device. Such a means for detecting movement may also be referred to as means for determining or detecting a movement applied by a person to the actuator. Such a means may be, for example, a torque, force, angle and / or rotational speed sensor. This allows an analysis of the movement applied by a user to the actuating element and thus to the movement element.

In one variant, the device has a control to which at least one of the movement elements, in particular each of the movement elements, is connected. In a variant, the control is also connected to any existing drives and / or means for detecting the movement applied by a person on the actuator movement. For example, it is possible to use in the control the movement detected by the means or means for detecting the movement applied by a person to the actuator as a controlled variable, such as to control the drive. Alternatively or additionally, parameters of the detected movement may be output on an output element, for example acoustically or on a display. One such output element, for example a display or a speaker, may be provided on an actuator or the base member. Then the output of the parameters takes place in the immediate vicinity of the user. It is additionally or alternatively also possible to make the output via a network. In particular, so more than two movement elements can be controlled by a control and so the training of multiple users are controlled simultaneously. The connection of the control to any existing drives, output elements, or means for detecting a movement applied by a person to the actuator movement can be wireless or wired.

With the help of the control different training modes can be realized. One possibility is a purely active training. Any existing drives then bring no force. The means for detecting a movement applied by a person to the actuator is read by the control. Measured torques, forces, angles or rotational speeds are evaluated by the control and used to create an individual training.

One possibility is symmetry training, which evaluates whether the user applies different movements to the two movement elements, for example, whether one leg is more kicked than the other, or whether the pedals are brought into different angular positions. Alternatively or additionally, a resistance to the movements of the user can be set, which is realized for example by two passive electric drives. With two such drives, left and right limb resistance can be controlled differently.

Another training mode is a semi-active training in which a drive acts only as a servo drive supporting the movements of the user. Measured torques, forces, angles or rotational speeds are evaluated by the control device and the drive or drives are controlled in such a way that they optimally support the movement of the user. If two drives are provided, the support for the left and right extremities can be controlled differently.
Yet another training mode is a passive training in which the user does not apply their own movements to the movement elements. Measured torques, forces, angles or rotational speeds are evaluated by the control device and the drives are controlled so that they optimally move the extremities of the user. Due to two separate drives, the movement of the left and right extremities can be different to be controlled. For example, the torques generated by the drives can be set individually to each extremity, z. For example, to relieve cramps, blockages or spasticity or to loosen up the muscles. Accordingly, convulsions, blockages or spasticity of a limb can be detected more easily, since measured torques, forces, angles or rotational speeds of both sides can be evaluated separately.

The basic element can be, for example, a base plate or a frame, which can be arranged, for example, on a table and / or floor. It can be arranged on a common base element several or all movement elements. In a variant, however, all movement elements are each arranged on a separate base element. As a result, a particularly great flexibility in the arrangement of the individual movement elements is achieved, so that an optimal adaptation of the device to the individual user and the specific application is possible. If several basic elements are present, then they can be coupled to each other movably, e.g. B. against each other rotatable or pivotable, or mechanically separated from each other.

At least one of the axes of rotation may be movable relative to the respective first axis of movement, taking any angle, for example in a range of 0 ° to 360 °, 0 ° to 180 °, 0 ° to 90 °, 80 ° to 100 ° or 60 ° to 120 °. An angle of 0 ° between the axis of rotation and the first axis of motion means that both are parallel to each other. An angle of 90 ° means that both axes are perpendicular to each other, that is, the axis of rotation is parallel to the surface in which the base member extends. In a variant, the movement axis may be perpendicular to the respective axis of rotation, alternatively or additionally, both axes may be immovable relative to each other. It is possible that the axes of rotation can be moved independently relative to the corresponding first axes of movement.

Preferably, the first movement axis is at least one of the movement elements or movement modules, in particular each of the movement elements or movement modules, an axis of rotation or a pivot axis. As a result, the movement element can be rotated relative to the base element, for example, about the first movement axis in the form of a rotation axis, which runs approximately centrally through the movement element. Alternatively or additionally, a movement can also take place about the first movement axis in the form of a pivot axis which runs eccentrically through the movement element. In this case, at least one of the movement elements, in particular each of the movement elements, by an angle of at least 90 °, in particular at least 120 °, in particular at least 150 °, in particular at least 180 °, in particular at least 210 °, in particular at least 240 °, in particular at least 270 °, in particular at least 300 °, in particular at least 330 ° and very particularly be movable at an angle of 360 ° about the first axis of movement. For example, movement ranges of the moving member or the moving members may be provided from 90 ° to 360 ° or any other interval that may be formed from the aforementioned angle indications (for example, 120 ° to 270 °). The upper and lower limits are included in the respective areas. By such a movement possibility, the flexibility of the device is further increased, so that, for example, the (fine) adaptation to the specific application or the user can be made only after the placement of the movement elements.

Optionally, an intermediate element is arranged between at least one of the base elements and at least one of the movement elements, wherein each intermediate element can be moved relative to the respective base element independently of another element between the respective first movement axis. Then this movement can be transmitted via the intermediate element to the movement element connected to the intermediate element, so that there is a mobility of the movement element around the first movement axis.

In a variant, the movement elements are movable relative to the respective intermediate element independently of one another about a second respective movement axis, the second movement axis being arranged substantially parallel to the surface in which the respective base element extends. The second movement axis is furthermore arranged substantially perpendicular to the first movement axis and also substantially perpendicular to the rotation axis. The particular effect of such an intermediate element is that a movement of the moving elements about a horizontally extending axis is made possible, for example, to unevenness of the base (ie, about a table or a floor) or inclinations of the stand auszubichen. In particular, the rotational axis of at least one of the actuating elements can thus be aligned so that it is substantially perpendicular to the extension surface of the respective basic element. The particular effect of such an alignment is to allow training of the ankle by moving the foot relative to the lower leg about a longitudinal axis of the lower leg.

It is possible, in each case, to attach an actuating element, which can be moved about the axis of rotation, directly to the movement elements. In one variant, however provided on the movement elements, an adapter for fixing such an actuating element, which is movable about the axis of rotation to provide. By such an adapter simple replacement of different actuators against each other is accomplished particularly easily. This is particularly the case when the actuator can be releasably attached to the adapter or is attached.

The actuating element may for example be a pedal, similar to a gas / brake or clutch pedal of a motor vehicle. This pedal can then be operated by the user as a corresponding vehicle pedal. That is, in such an operation, the pedal is rotated or pivoted about the rotation axis. As a result, for example, the user's ankle can be optimally trained.

The actuator may also be a pedal with a pedal arm, similar to a bicycle pedal. This can then be operated by a user, such as a bicycle pedal. The pedal is rotated with the pedal arm around the axis of rotation. This allows the user to train like on a bicycle ergometer. The corresponding pedal is movable in this case even with respect to the pedal arm.

The actuator may be in a further embodiment of the device a handle with a crank, similar to a handbike. This handle can then be operated by a user as in a hand bike, while the handle is rotated with the crank around the axis of rotation. This allows the user to train like on a handbike.

In each case an actuating element can be permanently or detachably attached to at least one adapter, in particular to each of the adapters. Detachably mounted actuators can be easily replaced, whereby damaged actuators can be replaced or with a moving element, in particular temporally successive different applications can be realized.

Preferably, means are provided for releasably fixing the movement elements against movement relative to the respective base element. These means may be, for example, screws or clamps. Alternatively or in addition, they can also be fixing bolts, that is to say pins which are respectively provided on the moving element or base element and engage in a grid, for example a drilling grid, which is provided on the respective other of the two elements. As a result, uncontrolled movements of the movement elements are avoided relative to the base element, which could change the setting made.

A concrete possibility of the embodiment of the device according to the invention is that two actuation elements are provided on a common base element, which are accommodated in a common housing, but nevertheless allow the above-described complete autonomous movement possibility of the individual movement elements.

One aspect of the present invention is the use of a device according to the previous explanations for exercising the lower and / or upper extremities. This training may be training without therapeutic purpose, for example, a purely athletic training without an intentional or unintended therapeutic effect. Alternatively, the training may also have a therapeutic purpose, for example as a rehabilitation measure following injury to the extremities by a disease or accident or lack of controllability of the extremities by the user, such as paralysis, for example, as a result of a stroke.

Thus, in one aspect, the invention relates to a therapeutic method of training the lower and / or upper extremities of a person in need of such training using a device as described above.

A further aspect of the present invention is a method for controlling a device according to the above explanations, wherein the movement elements are individually controlled by the common control element. The common control element may, for example, read out the means or means for detecting a movement applied to the actuating element and further process the control parameters thus read out. For example, these control parameters can be used as a control variable to control the drive accordingly. Alternatively or additionally, the control parameters can also be output, for example acoustically or on a display.

A further aspect of the present invention is a method for adjusting a device according to the above explanations, wherein the individual movement elements are moved individually around the axes of movement relative to the base element before the start of a workout and then releasably fixed against movement relative to the base element. Thus ends such a method for adjusting the device before starting training.

In an alternative embodiment, the above-described method for adjusting a device may also be a first step in a therapeutic method for training the lower and / or upper extremities of a patient using the device.

This also discloses the possibility of providing a common base element for at least two movement elements, wherein the movement elements can not be moved around a movement axis, but only in each case have an axis of rotation, around which in each case an actuating element can be moved.

All variants of the described device, the use and the different methods can be combined with one another in any manner and can be transferred from the device to the use and the methods and vice versa.

a fifth mode, which with the embodiment of the FIG. 1 or the FIG. 2 can be realized, namely a lying training.

The FIG. 1 shows as a first embodiment of a training device as a device for training the arms and / or legs of a person.

The training device comprises a first movement module 1 as a first movement element and a second movement module 2 as a second movement element. The first movement module 1 is arranged on a first base plate 3, which serves as the first basic element. The second movement module 2 is arranged on a second base plate 4, which serves as a second basic element. The shape of the first base plate 3 and the second base plate 4 is not critical to the function of the training device.

Between the first movement module 1 and the first base plate 3, a first movement plate 5 is arranged. Similarly, a second movement plate 6 is arranged between the second movement module 2 and the second base plate 4. The first movement plan 5 serves to enable a movement of the first movement module 1 relative to the first base plate 3 about a first movement axis 7 of the first movement module 1. In the same way, the second movement plate 6 serves to enable movement of the second movement module 2 relative to the second base plate 4 about a first movement axis 8 of the second movement module 2.

The first movement axis 7 of the first movement module 1 and the first movement axis 8 of the second movement module 2 are each substantially perpendicular to a first surface 9, in which the first base plate 3 extends, or to a second surface 10, in which the second Base plate 4 extends, arranged.

In other words, the first movement axis 7 of the first movement module 1 is then vertically aligned when the base plate 3 is arranged horizontally. This applies in a horizontal arrangement of the second base plate 4 in the same way for the first movement axis 8 of the second movement module. 2

The first movement module 1 further has a first axis of rotation 13, which is substantially perpendicular to the first axis of movement 7 of the first movement module 1 and is arranged substantially parallel to the first surface 9. Likewise, the second movement module 2 has a second rotation axis 14, which runs essentially perpendicular to the first movement axis 8 of the second movement module 2 and substantially parallel to the second surface 10. The first movement module 1 can be rotated around the first rotation axis 13. The second movement module 2 can be rotated and the second rotation axis 14 around.

In order to enable a simple rotation of the first movement module 1 about the first axis of rotation 13, a first adapter 15 is attached to the first movement module 1. This first adapter 15 is used for releasably securing a movable together with the first movement module 1 about the first axis of rotation 13 around actuating element. Similarly, a second adapter 16 is mounted on the second movement module 2, which serves for releasably securing an actuating element, with which the second movement module 2 can be moved about the second axis of rotation 14 around.

The first movement module 1 and the second movement module 2 each have their own electrical drive in order to ensure a movement of an attached to the first adapter 15 and the second adapter 16 actuator. These drives are in the representation of FIG. 1 Not shown. These drives make it possible to train even a purely passive user or to allow movement support of an active user of the training device. Through different drives left and right extremities and / or upper and lower extremities of the user can be addressed flexibly and differently. This is particularly advantageous if there are differences in the motor skills of the left and right or upper and lower extremities of the user.

The training device of FIG. 1 has a PC 19, which serves as a common control for the first movement module 1 and the second movement module 2. For this purpose, it is connected via an electrical line 20 both to the first movement module 1 and to the second movement module 2. Instead of the PC 19 and a notebook or smartphone could be used as a common control. The electrical line 20, which connects the first movement module 1 and the second movement module 2 to the PC 19, can also be realized by a network. In this case, both a wired and a wireless connection, for example via Bluetooth or WLAN is possible.

Instead of in the FIG. 1 illustrated variant of an external control by the PC 19, it would also be possible to integrate a corresponding control in the first movement module 1 or in the second movement module 2. Then no additional component would be needed for the common control.

Like in the FIG. 1 can be seen, the first base plate 3 and second base plate 4 are not mechanically coupled together. Such a constructive separation between the first However, the base plate 3 and the second base plate 4 does not exclude that the first movement module 1 and the second movement module 2 are connected via a common electrical line 20 to the PC 19.

The first movement axis 7 of the first movement module 1 and the first movement axis 8 of the second movement module 2 are rotation axes which permit rotation of the first movement module 1 or of the second movement module 2 and 360 °. If necessary, a lesser movement of the first movement module 1 about the first rotation axis 7 and / or the second movement module 2 about the first rotation axis 8 around can be adjusted.

Different actuators that can be attached to the first adapter 15 and to the second adapter 16, in connection with the FIGS. 3 to 7 be explained in more detail.

The FIG. 2 shows a further embodiment of a training device, which in essential aspects of the embodiment of the FIG. 1 equivalent. The same elements are provided with the same reference numerals. It is in this context to the above explanations of FIG. 1 referred to and discussed below only the differences between the two embodiments.

In the embodiment of FIG. 2 is disposed between the first base plate 3 and the first movement module 1, a first tilting holder 17, which serves as an intermediate element. A movement of the first tilting holder 17 relative to the first base plate 3 about the first movement axis 7 of the first movement module 1 leads to a similar movement of the first movement module 1 relative to the first base plate 3. In addition, it is possible, the first movement module 1 about a second movement axis 11th to move around. The second movement axis 11 is arranged substantially perpendicular to the first movement axis 7 and also substantially perpendicular to the first rotation axis 13. In this case, it runs essentially parallel to the first surface 9, in which the first base plate 3 extends.

In the same way, between the second movement module 2 and the second base plate 4, a second tilt holder 18 is arranged, which can be moved around the first movement axis 8 of the second movement module 2 around. Such a movement leads to a similar movement of the second movement module 2 relative to the second base plate 4. In addition, the second tilting holder 18 is also about a second movement axis 12 around movable, which is substantially perpendicular to the first movement axis 8 of the second movement module 2 and also substantially perpendicular to the second axis of rotation 14. In this case, the second movement axis 12 also extends parallel to the surface 10 in which the second base plate 4 extends.

An additional degree of freedom of movement for the first movement module 1 relative to the first base plate 3 and the second movement module 2 relative to the second base plate 4 can be achieved by the first tilting holder 17 and the second tilting holder 18. In the embodiment of FIG. 2 the second movement axis 11 of the first movement module 1 and the second movement axis 12 second movement module 2 are designed as axes of rotation about which the first movement module 1 and the second movement module 2 can each be continuously rotated or tilted, relative to an orientation of the first Rotation axis 13 and the second axis of rotation 14 parallel to the surface 10. After a corresponding rotation or tilting the first movement module 1 and the second movement module 2 can be determined in its rotated or tilted position.

The FIGS. 3 to 7 show possible operating modes of a device according to any of the two embodiments explained above. The show FIGS. 3 to 7 in each case the first movement module 1 and the second movement module 2, 16 different actuators were attached to the first adapter 15 and the second adapter.

The actuator can as in the FIG. 3 illustrated a pedal 21 with a Pedalarm 22, similar to a bicycle pedal. This can then be operated by a user, such as a bicycle pedal. In this case, the pedal 21 is rotated about the first axis of rotation 13 and / or the second axis of rotation 14 with the pedal arm 22. As a result, the user can exercise as on a bicycle ergometer if such pedals 21 with corresponding pedal arms 22 are attached to both movement modules 1, 2.

The actuator can as in the FIG. 4 shown a handle 23 with a crank 24 be similar to a handbike. This handle 23 can then be operated by a user like a handbike. In this case, the handle 23 is rotated with the crank 24 about the first axis of rotation 13 and / or the second axis of rotation 14. As a result, the user can exercise as on a hand bike if two handles 23 with cranks 24 are attached to both movement modules 1, 2.

The actuator can as in the FIG. 5 be a pedal 25, similar to a gas, brake or clutch pedal of a motor vehicle. This pedal 25 can then be operated by the user as a corresponding vehicle pedal. In this case, the pedal 25 is rotated or pivoted about the first axis of rotation 13 and / or the second axis of rotation 14. As a result, for example, the user's ankle can be optimally trained.

In all three variants mentioned above, the moving elements 1, 2 are usually aligned so that the first axis of rotation 13 and the second axis of rotation 14 are aligned substantially collinear with each other.

Alternatively, the first movement module 1 and the second movement module 2 can also as in the FIG. 6 be aligned. The first axis of rotation 13 and the second axis of rotation 14 are really aligned parallel to each other. The first movement module 1 and the second movement module 2 are further aligned so that a user can stand at the same time with each foot on each pedal 22 with a corresponding pedal arm 21 and can perform pivoting movements. The legs of a user are in the FIG. 6 for illustrative purposes shown in dashed lines in a schematic manner.

Another alternative to the alignment of the first movement module 1 and the second movement module 2 shows the FIG. 7 , The first axis of rotation 13 and the second axis of rotation 14 are in turn aligned real parallel. Furthermore, the first movement module 1 and the second movement module 2 are aligned such that a lying user can at the same time put one foot on each pedal 22 with a corresponding pedal arm 21 and can perform pivoting movements.
