Description

Training and / or rehabilitation device for training and / or rehabilitation, methods for training, rehabilitation and / or monitoring of training and / or rehabilitation measures and biofeedback and monitoring system

[01] The invention relates firstly to a training and / or rehabilitation device for exercising and / or rehabilitating with displaceable means for introducing muscle forces and with displaceable means for storing the muscular forces. Moreover, the invention relates to a biofeedback and / or monitoring system for monitoring rehabilitation measures for exercising and / or rehabilitating. The invention also relates to a method for training, rehabilitation and / or monitoring of training and / or rehabilitation measures, in which muscle forces are transferred to means for storing the muscular forces.

[02] Training and / or rehabilitation devices are known from the prior art, such as isokinetes, treadmills or trim wheels, by means of which, in particular, rehabilitation measures for regaining a normal mobility of a patient can be specifically carried out. It is known to equip such training devices with sensors, by means of which data can be determined for individual training and / or rehabilitation services and also temporarily stored for further evaluation. It is also possible to specify training and / or rehabilitation programs on many training devices, by means of which, in particular, rehabilitation measures of a patient can be supported.

In such training devices are usually structurally very large training equipment, which are used mainly due to their structural complexity mainly in this suitable training and / or rehabilitation centers.

[04] It is an object of the present invention to provide generic training and / or rehabilitation devices which are suitable for being used on a mobile basis, in particular in domestic areas of a patient, and moreover have the option of a professional feedback and monitoring system Offer.

[05] The object of the invention is a training and / or rehabilitation device for training and / or rehabilitation with displaceable means for introducing muscle forces and with relocatable Solved means for storing the muscle forces, which is also characterized by elastically deformable means for measuring the muscle forces introduced.

[06] Advantageously, the intensity of the introduced muscle forces can be determined structurally particularly easily by means of the elastically deformable means provided here, so that the present training and / or rehabilitation device has a simple and uncomplicated construction. This makes it possible to provide a somewhat susceptible training and / or rehabilitation device, which is robust enough to use it mobile.

[07] The term "means for initiating" muscular forces in the present case describes devices by means of which, for example, a patient can introduce his muscular forces into the training and / or rehabilitation device, for example, these are hand grips which the patient grasps.

[08] In order to further simplify the structure of the present training and / or rehabilitation device, a particularly preferred embodiment provides that the means for storing the muscle forces are elastically deformable.

[09] In this connection, the object of the invention is also achieved by a method for training, rehabilitation and / or monitoring of training and rehabilitation measures, in which muscle forces are transferred to means for storing the muscular forces and the muscle forces are measured by means of elastically deformable means become.

[1O] It is understood that means for storing the muscular forces can be implemented constructively diverse. For example, the means for storing the muscle forces often consist of counterweights, which must be lifted by means of muscle forces against gravity. Or the means for storing the muscular forces comprise a resistor which is constructed electromagnetically. Means for storing muscle forces having such a structure, however, are very heavy and therefore only limited mobile use. A use in a domestic environment is out of the question.

Structurally particularly simple and easy builds the present training and / or rehabilitation device, however, when the means for storing the muscle forces are elastically deformable, since these are usually much lighter than the means previously used previously described.

[12] Thus, elastically deformable storage means are also provided structurally simple if they comprise an elastic band, a spring or an elastic cord. The elastically deformable means may have a linear characteristic with regard to their force / strain behavior. However, if the means for storing the muscular forces have a non-linear force-elongation characteristic, the expenditure of force increases with increasing elongation of the means for storing, so that with increasing elongation of the elastic means the forces to be expended must become stronger.

[13] A further preferred embodiment provides that the means for measuring the introduced muscle forces comprise the means for storing the muscle forces. If the means for measuring the introduced muscle forces and the means for storing the muscular forces are structurally combined, the training and / or rehabilitation device is particularly lightweight and compact. In particular, this provides the opportunity to carry out rehabilitative measures for restoring mobility in the private environment of the patient by means of a lightweight device. This also ensures that the patient is supported by a feedback in his exercises, since the muscle forces introduced are measured.

[14] In particular, rehabilitations can be significantly improved and the patient can thus recover faster. But also in the wellness sector as well as in terms of preventive or otherwise targeted training, the training results are particularly easy to increase with this targeted feedback, especially in the home area.

Accordingly, it is procedurally advantageous if the storage means elastically deformed by interacting with the muscle forces and the muscle forces are measured by means of elastically deformable means.

A method variant advantageously provides that the muscle forces are measured between means for introducing the muscle forces and the means for storing the muscle forces.

[17] In addition, it is advantageous if the muscle forces are measured by means of an elongation of an elastically deformable means. The degree of elongation provides information about the intensity of the introduced muscle forces.

[18] A further advantageous variant of the method provides that by means of the measured values, a feedback on the effectiveness of the movement executions is provided optically, acoustically and / or haptically. For example, an optical feedback can be present in such a way that deflections of a beam due to a train on a sensor unit are displayed by means of LCD displays or LED rows. Also, for example, listed feedback administration forms can be freely rotatably displayed on screens or displays in a display device in order to be able to carry out the intended operation to be carried out. to facilitate the feedback interpretation for a person performing the exercise. It is understood that in addition to the aforementioned LCD displays, other displays, such as TFT displays, can be used.

[19] Cumulatively, a further embodiment provides that the training and / or rehabilitation device has means for measuring a displacement of the means for introducing the muscle forces and / or the means for storing the muscle forces. A sequence of movements can thus be largely documented.

[20] It is also advantageous if the training and / or rehabilitation device has means for measuring a change in length of the elastically deformable means and / or the means for storing the muscle forces, as this further conclusions on the training implementation are possible.

[21] A further improvement in the function of the present training and / or rehabilitation device is achieved if the device comprises means for measuring a time course of a force introduction, a displacement of the means for introducing muscle forces, a displacement of the means for storing the muscle forces and / or Length change of the elastically deformable means.

[22] Further advantageous feedback information can also be determined if the training and / or rehabilitation device comprises means for measuring stresses on the elastically deformable means.

[23] Alternatively, another embodiment provides means for transmitting power between the means for initiating and the means for storing.

[24] An elastic basic body of a means for measuring in particular muscle forces introduced is provided particularly advantageously if at least one of the measuring means comprises a Z-shaped, a V-shaped or a U-shaped basic body. By means of a base body formed in this way, a bending region in which a force measurement can be advantageously carried out can be provided structurally in a simple manner. In addition to these one-dimensionally operating sensors, multidimensionally operating sensors can also be used, which, however, would increase the structural complexity.

[25] In order to be able to determine changes, in particular in the bending region, it is advantageous if the training and / or rehabilitation device has one or more strain gauges. [26] If a strain gauge is arranged in a region of a base body that is structurally weaker than other base body regions, the detection of deformations on the base body is particularly sensitive.

[27] A further preferred embodiment provides that the elastically deformable means for measuring the introduced muscle forces, the means for measuring the displacement, the means for measuring the change in length, the means for measuring the time course and / or the means for measuring Strains form a sensor with a base body comprising a twisting area and a torsion-free area, and in the twisting area a first strain gauge and in the torsion-free area a further strain gauge is arranged.

[28] Feedback on the quality of motion execution is particularly advantageous by means of the changes made to the strain gauges. The advantage here is that a first strain gauge is placed in a twisting area and another strain gauge in a torsion-free area, whereby the influence of temperature fluctuations and thus caused Messwertverfälschungen be compensated or ideally completely excluded.

[29] In addition, if the sensor comprises a Z-shaped main body which has a center leg with a bore which reduces the center leg cross-section, forces acting on the main body will preferably twist the middle leg.

Therefore, a particularly advantageous embodiment variant provides that the center leg with the bore forms the twist region of the sensor.

It is understood that the present training and / or rehabilitation device may include data processing means for processing the determined values. In this context, in order for feedback to be displayed to a trainee or a patient, it is advantageous if the training and / or rehabilitation device comprises means for displaying and signaling instructions.

[32] A structurally preferred embodiment provides that the means for measuring are arranged at a force introduction region of the means for storing the muscle forces. This makes it easier to form the means for storing the muscle forces in one piece. In addition, a Kabelftlhrung example, simplified to an evaluation. [33] Means for measuring are attached to the training and / or rehabilitation device particularly advantageous when the means for measuring are arranged on a frame support of the means for storing the muscle forces.

[34] The information content of a feedback can be further improved if further means for measuring an acceleration, a magnetic field and / or a position of one of the aforementioned forces of force are provided.

[35] It is also advantageous if means for measuring are arranged on a handle, since the muscle forces are introduced directly here.

[36] It is understood that in the present case additional motion sensors, for example for measuring an acceleration, a magnetic field, or gyroscopic motion sequences, or in particular position sensors for determining an alignment and a direction of movement of an executing end effector of the affected limb can be provided in such a way that, in particular Deviations between predetermined and executed movement can be detected and evaluated.

[37] The object of the invention is also solved by a biofeedback and / or monitoring system for monitoring rehabilitation measures for exercising and / or rehabilitating, which has a training and / or rehabilitation device with at least one of the features explained above.

With the present invention applied forces and a related path and their temporal courses are recorded, which exerts the patient during his athletic or therapeutic exercises on an elastic element. In this way, in particular, a measure is determined which allows conclusions to be drawn about the mechanical force components of the articulated chain. Based on this a feedback is generated, which guides the patient during his exercises.

[39] As already explained, the feedback can be visual, haptic and acoustic. In addition, it can in particular be integrated directly into a sensor unit or can also be realized by PCs, handhelds, smartphones or other mobile systems, such as notebooks, as well as stationary systems. In particular, this makes it possible to guarantee a very cost-effective and optimal care even with increasing numbers of patients.

[40] Due to the available training and / or rehabilitation equipment or the present biofeedback and / or monitoring system therapists are relieved and a recovery accelerates or optimizes a workout accordingly. The patient regains his motor skills as early as possible and gains in quality of life.

[41] It is particularly advantageous that the patient can return to his home environment faster after surgery and be able to fulfill his employment. The present biofeedback training system reduces the socioeconomic costs associated with the disease.

[42] By recording and saving exercise files and / or transmitting the recorded or saved exercise files via data communication paths, such as via cable, wireless or data storage media, to experts, it is possible at a later date, the exercises performed and have their successes assessed by a therapist. In this way, checks and evaluations of the exercises can be done by an expert at any time.

[43] Through the interaction of the sensors for recording the motion and the software used for processing, storing, forwarding the data and generating the feedback, a system is provided which enables an optimal biofeedback training program. This system can be extended by dialysis or training centers as well as by rehabilitation centers, which can centrally evaluate the data and intervene if necessary, intervening or optimizing. They form a second feedback loop in addition to the direct feedback that guides the patient during his practice.

Particularly advantageous in the present case is the construction of a biofeedback training system, based on a sensor system for elastic elements, which detects in particular the elongation and the tensile force on a band and its tension. This allows the monitoring of the individual exercises as well as the adherence to the prescribed training plan. The biofeedback training system introduces the patient or the user in his exercises and enables a continuous increase in the exercise requirements depending on the individual training success. The patient is recorded quantitatively in his training and can be monitored particularly advantageous.

In addition to supporting patients who require the rehabilitation measures to regain their mobility, the present invention can also advantageously train a patient in the context of wellness or other training projects. The system is also inexpensive to provide, easy to transport and both in fitness or wellness studios, in physiotherapy practices, but also in a patient's home environment can be used. Furthermore, the present training system for the targeted physiotherapeutic training of both the upper and lower extremities, as well as back and trunk is advantageously suitable. It is not based on elaborate exercise equipment, such as those found in rehabilitation centers or gyms, but provides a simple, safe and cost-effective alternative. Therefore, as a basis for the biofeedback system, especially for home rehabilitation, elastic elements, such as For example, selected tapes, springs, ropes, fabric or the like.

By means of an elongation of these elements, the information about the range of motion and the forces applied by the patient during his exercise session is determined.

[48] Based on the elongation of the elastic elements by the patient during his exercise sessions, the patient is given biofeedback, which provides information about his training performance. A sensor integrated in the training system monitors the change in the extent of the elastic element and passes on the resulting information about the quality of the exercise procedure directly to the patient. This information is used to control, but also to guide the patient in performing the exercises, so that there is direct feedback. The exercise is thus quantitatively recorded and the Übungsdurchfuhrende monitored advantageous.

[49] The training program can be individually tailored to the patient or trainer as a guideline by the trainers, doctors or therapists, but also by written instructions as well as videos or graphics. The biofeedback system, in particular for home rehabilitation, preferably responds to the performance of the user and adapts the training program to his individual needs. The direct feedback on the quality of the executed training components can hereby be presented to the patient visually, acoustically or haptically.

In the present case, obtained measurement results can advantageously be stored for later control and read by a treating trainer or therapist, for example, so that in addition to direct feedback between the device and the exerciser, indirect feedback is also possible. For example, in the latter case, the measurement results via data networks, such as wireless or wired networks, to appropriate experts or institutions responsible for therapy forwards. This allows the monitoring of the exercise by experts at any time. [51] Also advantageous in this context is a tensile force sensor assembly for an assembly and a method for detecting and detecting the movement performed by a movement performer, so that a biofeedback about the quality of the movement execution can be given directly to the movement executors, wherein the tensile force sensor assembly comprises a first strain gauge, wherein the tensile force sensor assembly is Z-shaped, whereby the distortion of said assembly is increased in externally applied forces, wherein the central Z-leg has a bore to the torsion on the thinner outer walls of a Metal piece, wherein attached to the thinner outer walls of said strain gauge, which detects the twist, wherein the twisting of said thinner outer walls is proportional to the externally engaging force, and wherein the tensile force sensor assembly a second strain gauge a The sensor assembly is constrained to be virtually non-negligible or slightly out of range of the outer walls of the solid portion of the central Z-leg which are thinned by the bore, said second strain gauge being out of the range of said outer walls of the solid portion of the central Z And is used for temperature compensation of the torsion detected by said first strain gauge, the elastic unit being connected to said sensor assembly via said coupling assembly such that the force on the elastic unit forces the sensor array along the force on the elastic unit deflects.

[52] In addition, an assembly is advantageous in which the said signal of the detected movement is received by the data acquisition module, fed to a data evaluation method and fed back by means of a feedback module in a suitable form to the operator.

[53] Further advantages, objects and features of the present invention will be described with reference to the following attached drawing in which, by way of example, a training and / or rehabilitation device and its possible uses as well as components of the training and / or rehabilitation device are shown.

The rehabilitation device 1 shown in FIG. 1 is in an application of a patient 2. The rehabilitation device 1 comprises an elastic resistive training band 3, which in the present case represents a means for storing muscular forces. The said muscle forces are introduced via a handle 4 of the patient 2 in the elastic training band 3, so that this is loaded on train 5. The elastic training band 3 has a grip loop 7 at its end 4 opposite the handle 4. Between the retaining loop 7 and the elastic training band 3, a tension sensor 8 is provided, which is used in this embodiment as an elastically deformable means for measuring the introduced muscle forces.

[56] The data determined by the train sensor 8 are transmitted in the present case by means of a data transmission cable 9 to a data processing system 10. Here, the data are processed by means of a suitable software and in this exemplary embodiment are displayed visually as feedback via a monitor 11 and acoustically via a loudspeaker 12 to the patient 2. Thus, the patient 2 receives on the one hand an optical feedback 13 and an acoustic feedback 14. The optical feedback 13 can hereby be generated from LED rows. The deflection of an optical LED bar indicates the effectiveness of a movement execution. Such LED displays can also be displayed freely rotatable so as to indicate to the patient 2 the intended direction of movement.

[57] By means of the acoustic feedback 14, the patient 2 can be indicated by sounds as to how he has to perform or change a movement. If necessary, linguistic instructions can also be given to the patient 2. The data networking 20 of a home environment and a support environment 22 shown in FIG. 2 shows a first possibility of how rehabilitation with the rehabilitation apparatus 1 in the home environment 21 can be performed and the remote support rehabilitation apparatus 1 by means of a suitable one WLAN network 23 is connected.

By means of the WLAN network 23 provided in this embodiment, an external feedback loop 25 is provided between the patient 2 in the home environment 21 and a doctor 26 in the present case.

[60] If the patient 2 in the home environment 21 carries out a physiotherapeutic exercise 27 with the rehabilitation device 1, for example, corresponding movement data 28 are acquired by means of the rehabilitation device 1 and objective data 29 are obtained for the external feedback loop 25 and for another an internal feedback loop 30 for the patient 2 to the monitor 11 and to the speaker 12 as optical feedback 13 and acoustic feedback 14, respectively.

[61] By means of the data networking 20 shown here, the patient 2 receives on the one hand, directly by means of the inner feedback loop 30, feedback on his movement execution. On the other hand, by means of the external feedback loop 25, the patient 2 indirectly receives feedback, for example, from a training schedule 32 updated by the doctor 26. The patient 2 is thereby able to carry out his rehabilitation in the home environment 21 and needs the doctor only occasionally 26 as patient 2 'to discuss rehabilitation measures 32 in person with the doctor 26.

[62] The support environment 22 can be a hospital, a doctor's office, or a rehab center.

[63] The sensor principles illustrated in FIGS. 3 to 8 show in FIGS. 3 and 4 a sensor operating in series, in FIGS. 5 and 6 a sensor operating in parallel, and in FIGS. 7 and 8 a pseudo-serial sensor.

The serially working train sensor 40 is arranged as a bending beam 41 between a training band end 42 and a training band beginning 43 such that the training band end 42 and the training band beginning 43 of an elastic training band 44 are linked together. If the elastic training band 44 is loaded with tensile forces 45, the bending beam 41 experiences a bend 46, which provides information about the intensity of the applied tensile forces 45. [65] In the embodiment of FIGS. 5 and 6, an elastic training band 50 is designed to be continuous with regard to its training band end and its training band beginning 52. On the elastic training band 50, only one parallel working train sensor 53 is provided as a bending beam 54. When a tensile force 55 is exerted on the elastic training band 50, the bending beam 54 is bent in accordance with the bend 56, whereby conclusions can be drawn on the introduced tensile forces 55.

[66] In the embodiment according to FIGS. 7 and 8, a pseudo-serial train sensor 60 is arranged on an elastic training band 61. If the elastic training band 61 is subjected to tensile forces 62, it is tightened and thereby a movably mounted encoder 63 is deflected relative to a transmitter housing 64 according to the deflection 65, whereby the tensile forces 62 are measurable, which act on the elastic training band 61.

[67] The U-shaped sensor 70 shown in FIG. 9 is fastened with its first leg 71 to a housing 72 of a rehabilitation device. The second leg 73 includes a suspension 74 to which tensile forces 75 engage and thereby deform the U-shaped sensor 70 in its bending region 76. This deformation is detected by means of a strain gauge 77 provided in the bending region 76. Corresponding data for this purpose are then forwarded to a data processing system not shown here.

The z-shaped sensor 80 shown in FIG. 10 is fastened to a housing 82 by a first leg 81. On a second leg 83, a suspension 84 is provided, on which tensile forces 85 act on the z-shaped sensor 80. The first leg 81 and the second leg 83 are connected by a middle leg 86. The middle leg 86 forms a bending region 87 of the z-shaped sensor 80, since it is made weaker than the first leg 81 and the second leg 83.

[69] In order to advantageously measure a bend in the bending region 87, a strain gauge 88 is attached to the middle leg 86 in the bending region 87. If tensile forces 85 now act on the z-shaped sensor 80, in particular the middle limb 86 deforms rather than other regions of the z-shaped sensor 80 due to its cross-sectional weakening. These deformations are detected by the strain gauge 88 and by means of corresponding data passed on to a data processing system not shown here.

[70] The sensor 91, shown as a bending beam 90 shown in FIG. 11, is arranged on a housing 92 of a rehabilitation device. Attached to a suspension 93 of the sensor 91 is an exercise band 94, the suspension 93 having both a rotation 95 about the Z-axis and a rotation 96 can drive around the X-axis. This results in a very flexible storage of the exercise band 94 on the sensor 91st
