Description

[0001] Method for setting up an orthopaedic device

[0002] The invention relates to a method for the computer-based adjustment of an orthopedic device worn on the body of a patient equipped with it. The invention also relates to a system for this purpose.

[0003] For the purposes of the present invention, orthopedic devices include, in particular, orthoses, prostheses, exoskeletons, and possibly also wheelchairs. Orthoses are products that support, assist, protect, or restrict the movement of a patient's body part, such as a joint, in order to prevent excessive strain. Prostheses, on the other hand, do not replace, or no longer replace, the patient's body parts. Exoskeletons are, in particular, mechanical support structures designed to support, assist, or protect the patient's main musculoskeletal system.

[0004] In the following, a patient is defined as any user of the orthopedic device. This refers to the wearer of the orthopedic device.

[0005] Every orthotic device is attached to a part of the patient's body. It does not necessarily have to come into contact with the patient's skin. Orthoses and exoskeletons, for example, are often worn over clothing, so that the clothing, such as trousers, is between the orthotic device and the patient's skin. However, a knee orthosis, for example, is attached to the patient's knee or leg. A prosthesis always has an interface element connected to an amputation stump or another body part, which is attached to the respective body part. A leg prosthesis, for example, uses a prosthetic socket that represents the interface between the prosthesis and the amputation stump. In this case, the amputation stump would be the patient's body part.A liner is typically used between the skin surface of the patient's amputation stump and the prosthetic socket to reduce shear forces acting on the skin.

[0006] A prosthetic socket for an amputation stump is typically made of a rigid (hardly deformable) material, such as fiber-reinforced plastic, and forms an important part of the interface between the amputation stump and the prosthesis attached to the socket. Such prosthetic sockets have long been used, particularly for leg prostheses that are to be attached to an amputation stump, such as a femoral stump.

[0007] Prosthetic sockets for leg amputees, in particular, are subjected to particular stresses in daily use. When walking, the patient's entire weight rests on the prosthetic socket, and thus particularly on the amputation stump, which is housed within the prosthetic socket. It is therefore of utmost importance to adapt the prosthetic socket as optimally as possible to the patient's individual circumstances and needs, especially to the shape and geometry of the affected body part.

[0008] During both the assembly and adjustment of an orthopedic device, the patient is assisted by a technically trained user, such as an orthotist. With their knowledge and experience, the orthotist can make the necessary adjustments to ensure the orthopedic device fits optimally and provides a gentle movement pattern.

[0009] EP 2 153 370 B1 discloses a system for aligning prostheses, in which both movement data of the person fitted with the prosthesis and prosthesis alignment errors are determined from a movement database. These are compared to determine whether the prosthesis corresponds to a target value or requires further adjustment.

[0010] From DE 10 2012 009 507 A1 a method and a device for determining malpositions in the construction of prostheses of the lower extremities is known, wherein inertial measurement data are determined over at least one gait cycle and compared with target values.

[0011] DE 10 2018 128 514 B4 discloses a method for performing a static prosthesis assembly, wherein several components are arranged next to one another. The actual position and actual orientation of the arranged components relative to one another are determined based on recorded positions and orientations of markings and compared with corresponding target values.

[0012] Against this background, it is the object of the present invention to propose an improved method for setting up an orthopaedic device.

[0013] The object is achieved according to the invention with the method according to claim 1. Advantageous embodiments of the invention can be found in the corresponding subclaims.

[0014] According to claim 1, a method for computer-based adjustment of an orthopaedic device worn on the body of a patient equipped therewith is proposed, the method comprising the following steps:

[0015] - Recording status and / or movement-related data of the orthopaedic device during a movement sequence in which the patient in question performs a movement with the orthopaedic device,

[0016] - Transferring the recorded status and / or movement-related data of the movement sequence to a reality augmentation device used by a user, and

[0017] - Displaying at least part of the transmitted status and / or movement-related data and / or information derived therefrom as a reality extension into the reality perceived by the user by the reality extension device.

[0018] Setting up an orthopedic device involves not only adjusting the device's adjustable parameters, but also the selection and / or replacement of components, their arrangement on the patient's body, and / or the alignment of various components relative to one another. This method is intended to evaluate the outcome of the treatment and then modify it if necessary.

[0019] According to the invention, status and / or movement-related data of the orthopedic device are initially recorded during a movement sequence. The recording of the status and / or movement-related data of the orthopedic device can be carried out with the help of sensors or sensor systems that are arranged on the orthopedic device, integrated in the orthopedic device and / or provided outside the orthopedic device. These can be sensors that are inherently included in the orthopedic device and remain there during normal use by the patient. The movement-related data is generally the information that results directly from the patient's movement with the orthopedic device and can be determined as physical parameters with the help of sensors. Such parameters can be, for example:determined joint angles, acting forces, torques, speeds and / or movement trajectories. The status-related data are usually fixed settings that are set on the orthopedic device (usually unchanged even during movement or whose changes follow fixed rules). Such status-related data can, for example, be damping settings of prostheses with knee and / or ankle joints, where, for example, a damping curve can be specified over the gait cycle. Preferably, this status-related data also includes information on the state of the prosthesis control, for example, in which of the various modes such as stair climbing, cycling or level walking it is currently in, which part of the gait cycle has just been detected, whether the device is loaded and to what extent. E.g.The damping level changes during the gait cycle, whereby a different damping profile over the gait cycle can be selected for different modes such as running or walking or ramp up, ramp down, which is also referred to as status-related data. Sensors can be, for example, cameras and / or depth sensors that use image analysis to determine corresponding status and / or movement-related data of the orthopedic device. Inertial sensors that record acceleration values ​​in at least three spatial directions are also conceivable, allowing information about force vectors and directions of movement to be determined. Force sensors that are arranged inside the orthopedic device or that are located outside the device, for example a force plate, are also conceivable.However, sensors designed to detect angles of bendable devices or to detect other physical parameters are also conceivable.

[0020] This captured status and / or movement-related data of the movement sequence is then transmitted to a reality augmentation device used by the user, for example, an orthopedic technician or other specialist. With the help of the reality augmentation device, the previously captured and transmitted status and / or movement-related data and / or information derived from them are then superimposed as a reality augmentation into the reality perceived by the user.

[0021] With the help of the present invention, it is thus possible for the user, in particular the orthopedic technician, to immediately have the necessary data and information of the orthopedic device displayed in the real-world field of view during the adjustment or assembly of an orthopedic device, so that the user can immediately derive appropriate measures for adjusting the orthopedic device. The orthopedic technician is thus able to view the status and / or movement-related data of the orthopedic device recorded during the movement sequence while the patient is moving with the orthopedic device in question, and thus to immediately correlate the movement sequence data with the real-world perception of the movement sequence.Preferably, the user can also make changes to the setting parameters of the orthopedic device via the reality augmentation devices and directly implement the conclusions drawn. This can be done, for example, using an acoustic input (e.g., voice commands). According to one embodiment, at least some of the transmitted status and / or movement-related data and / or information derived therefrom are superimposed by the reality augmentation device as a reality augmentation during the movement sequence into the reality of the movement sequence perceived by the user.

[0022] Ideally, the prosthetist will be able to view the recorded movement-related data as well as the status-related data in the form of the orthopedic device's settings during the patient's movement, without having to take their eyes off the patient's movement to capture the information. Rather, the status and / or movement-related data are directly integrated into the movement view, thus enabling the best possible movement analysis of the orthopedic device. This has the particular advantage that the prosthetist can interact with the patient as usual during the movement sequence and, for example, give them instructions.

[0023] According to one embodiment, it is provided that the movement sequence of the movement performed by the patient in question with the orthopaedic device is recorded by means of a camera connected to the reality augmentation device and, depending on the recorded movement sequence, at least one location-accurate display position is determined with which the data and / or information correlate, wherein the transmitted status and / or movement-related data and / or the information derived therefrom are displayed as a reality augmentation in the reality perceived by the user at the determined position in a location-accurate manner.

[0024] In this case, the relative orientation of the reality augmentation device with respect to the movement sequence of the patient in question is determined in order to display the respective status and / or movement-related data to the user in reality at the point to which the status and / or movement-related data with respect to the orthopaedic device refer.

[0025] According to one embodiment, it is provided that a movement sequence or a part thereof stored in a data memory and previously recorded is provided, wherein the stored and previously recorded movement sequence or a part thereof is displayed as a reality extension in the reality perceived by the user by means of the reality extension device.

[0026] This allows the orthotist or user to compare previous movement sequences with the current, perceived movement sequence in reality. This allows them to compare the adjustments and settings made with the previous movement sequences and study their effects. The stored movement sequence can be a stored, optimal movement sequence or a previously recorded movement sequence with the same patient, perhaps with different settings.

[0027] According to one embodiment, it is provided that the data and / or information are displayed on a display device worn in front of the user's eyes in such a way that the data and / or information are superimposed as an extension of reality into the reality perceived by the user.

[0028] In this case, reality is captured directly by the user's visual senses, and the necessary data and / or information is superimposed onto the reality perceived by the visual senses using the reality augmentation device, thus expanding the perceived reality. This can be achieved, for example, using projection glasses, where the data is projected or displayed onto the glass surface of the glasses.

[0029] According to one embodiment, it is provided that the movement sequence of the movement performed by the patient in question with the orthopaedic device is recorded by means of a camera connected to the reality augmentation device and played back in real time on a display of the reality augmentation device, wherein the data and / or information are superimposed into the representation of the recorded movement sequence played on the display as a reality augmentation into the reality perceived by the user.

[0030] In this case, reality is recorded by a camera and presented 1:1 on a display, allowing the user to perceive the reality presented on the display using their visual senses. The reality extension is then overlaid onto this representation through the additional data and / or information, so that the originally recorded and presented reality is enhanced by the data and information.

[0031] According to one embodiment, it is provided that the status and / or movement-related data are acquired by a sensor source external to the orthopedic device, by a sensor source integrated in the orthopedic device and / or by a patient-related sensor source attached to the patient.

[0032] According to one embodiment, it is provided that the movement sequence of the movement performed by the patient in question with the orthopaedic device is recorded by means of a camera connected to the reality augmentation device and that, by means of an evaluation unit, movement-related data and / or information derived therefrom are determined from the recorded movement sequence by means of image recognition carried out on the evaluation unit, which information is then displayed as a reality augmentation.

[0033] In this case, the patient's movement sequence with the orthopedic device is recorded using a recognition device, and corresponding data and / or information is derived from this. The camera, together with the recognition device, forms a type of sensor system. The movement-related data obtained from image recognition and / or information derived from it are then superimposed into the user's captured reality as a reality extension using the reality augmentation device.

[0034] According to one embodiment, it is provided that setting parameters of the orthopaedic device are transmitted to the reality augmentation device as status-related data and / or information derived therefrom or are already stored there and are displayed as a reality augmentation in the reality perceived by the user.

[0035] According to one embodiment, it is provided that target specifications relating to status and / or movement-related data and / or information derived therefrom are provided in a database, wherein at least some of the target specifications are read from the database and displayed as a reality extension in the reality perceived by the user.

[0036] This allows the orthotist or user to view not only the recorded status and / or movement-related data and / or information derived from them as actual values, but also the corresponding target values ​​as target values ​​in augmented reality, enabling quick comparison. Preferably, any deviation between the achieved actual values ​​and the target values ​​is also displayed.

[0037] According to one embodiment, it is provided that a target movement sequence is provided in a database, wherein at least a part of the target movement sequence is read from the database and displayed as a reality extension in the reality perceived by the user.

[0038] The target movement sequence is therefore a desired movement sequence, whereby such a desired movement sequence or a part of it is presented to the user in the perceived reality as an extension of reality, so that during a movement analysis the user can carry out a comparison between the displayed target movement sequence and the actual real movement sequence.

[0039] According to one embodiment, it is provided that, with the aid of an evaluation unit, deviations from the target movement sequence are determined as a function of the status and / or movement-related data and / or information derived therefrom and are displayed as an extension of reality into the reality perceived by the user.

[0040] Such deviations from the target movement sequence, i.e. deviations of the actual values ​​from the specified target values, can be visualized and overlaid into the perceived reality as a reality extension. In this case, it is conceivable that the evaluation unit is set up to compare the recorded status and / or movement-related data with the stored target movement sequence and thereby determine corresponding deviations. According to one embodiment, it is provided that the movement sequence of the movement performed by the patient in question with the orthopedic device is recorded using a camera connected to the reality extension device, and a virtual twin is created using an evaluation unit and stored in a data memory.

[0041] Such a virtual twin includes in particular the orthopaedic device and the movement sequence of the patient carried out with it and enables the representation of the movement sequence of the orthopaedic device and the patient from different viewing directions in order to be able to carry out the best possible and comprehensive movement analysis.

[0042] According to one embodiment, it is thus provided that after the movement sequence has been recorded, the virtual twin is displayed in the user's field of vision as an extension of reality.

[0043] According to one embodiment, it is also provided that, depending on a change in the setting values ​​of the orthopaedic device and / or by a simulation of external influences on the movement sequence, a changed movement sequence of the virtual twin is calculated by means of a computing unit, wherein the changed movement sequence is displayed in the user's field of vision as an extension of reality.

[0044] This makes it possible to visually capture the effects of a change in the settings of the orthopaedic device directly in the perceived reality.

[0045] According to one embodiment, it is also provided that the evaluation unit determines a deviation between the recorded status and / or movement-related data of the orthopedic device and the information derived from the virtual twin and displays this deviation in the user's field of vision as an extension of reality. It is thus conceivable that the evaluation unit, with the aid of an image recognition unit, recognizes movement-related data of the orthopedic device from the recorded virtual twin and then compares this with sensor-supported, recorded movement-related data of the orthopedic device. The result of this comparison, in particular a correspondingly detected deviation, is then displayed in the user's reality as an extension of reality, so that it can be determined whether the corresponding sensors of the orthopedic device are still functioning correctly.The object is also achieved according to the invention with the system for setting up the orthopedic device according to claim 17, wherein the system is configured to carry out the method as described above. In particular, the system has a reality augmentation device, which can be connected in particular to a camera or comprises a camera. Furthermore, an evaluation unit is provided, which can be controlled, for example, by a microprocessor or microcontroller and is configured accordingly to carry out the method described above.

[0046] The invention is explained in more detail by way of example with reference to the accompanying figures. They show:

[0047] Figure 1 schematic representation of the device for carrying out the method;

[0048] Figure 2 Representation of a prosthetic foot with additional information;

[0049] Figure 3 Representation of a gait analysis;

[0050] Figure 4 schematic representation of further information representations;

[0051] Figure 5 schematic representation of a misconfiguration;

[0052] Figure 6 schematic representation of a superimposed movement sequence.

[0053] Figure 1 shows a highly simplified schematic representation of a reality augmentation device 10, which, in the embodiment shown in Figure 1, has a computing unit or evaluation unit 11 and a projection device 12. The computing unit or evaluation unit 11 is designed such that, depending on the application, appropriate programs can be executed, for example, image recognition programs. The computing unit 11 is, in particular, a microprocessor- or microcontroller-controlled computing unit.

[0054] The projection device 12 is shown in the form of glasses in the exemplary embodiment of Figure 1, but can also take other technical forms, for example, a mobile smartphone with a camera and display. The projection device 12 has two glasses 13 in the form of glasses, which are held in front of the eyes of the user or orthopedic technician when the glasses are worn. Corresponding data or information 20 can then be projected or displayed onto or into the glasses 13, specifically in such a way that the data / information 20 displayed on the glasses 13 becomes perceptible in the field of vision 100 as data / information 20'.

[0055] In the exemplary embodiment of Figure 1, a prosthesis 30 with a socket, knee joint, and prosthetic foot is located in the field of view 100. Status and / or movement-related data are recorded from the prosthesis 30 and transmitted to the computing unit 11. Furthermore, it is conceivable that other external sensors are provided, which record corresponding movement-related data and transmit them to the computing unit 11. Such sensors can, for example, be a force plate on which the prosthesis 30 rolls.

[0056] Using the reality augmentation device 10, various data / information 20, 20' can now be superimposed into the field of view 100. These data / information are recorded during the movement and provided by the sensors of the prosthesis itself or external sensors. Such parameters can be, for example, the relative angle between the lower leg in space and the knee angle, axial forces, ankle torque, IMU data (orientation and trajectories in space), knee moments, and / or knee angles.

[0057] The orthopedic technician using the reality augmentation device 10 thus has visual contact during the movement of the prosthesis 30 on the one hand and, at the same time, visual contact with the acquired data / information 20' within his field of view of the 100. In this illustration, the arrows indicate various measured values, for example, ankle and knee angles, ground reaction forces, lower leg angles and thigh angles.

[0058] Figure 2 shows a schematic representation of what the orthotist might perceive when wearing the projection device 12 from Figure 1. It depicts a mechatronic prosthetic foot 31, for which additional information is displayed, such as the ground inclination (both the real inclination and that determined by the foot), ankle moment, ankle angle, and IMU data (trajectory and orientation in space) shown at the top left. In addition, status information 2T of the prosthesis 30 (Figure 1) is shown at the top right. Here, the setting value for the dorsiflexion damping D and plantar flexion damping P is displayed, as well as the current mode, which here symbolically represents the "ramp down" mode.

[0059] Figure 3 shows a schematic representation of a gait cycle of a patient 200 with a prosthetic knee and foot. Using the reality augmentation device, the force vector 22' is displayed, and the position 23' of the lower leg in space is highlighted at selected points in time. This information is displayed at the position of the patient 200 while they move and perform a corresponding movement sequence with their prosthesis. If necessary, this information can also remain stationary in space, even after the patient 200 has already moved on or completed the movement.

[0060] Alternatively, additional information can be displayed, such as the progression of the knee angle throughout the entire gait cycle. This can also determine deviations from existing data, allowing the user to evaluate the gait pattern.

[0061] Figure 4 shows a patient 200 with a prosthesis 30 with a prosthetic foot and knee. Patient 200 moves forward and is stabilized by two support rods.

[0062] Using a camera (not shown), the 24' impact points can be captured as movement-related data and displayed in the orthotist's field of view, precisely at the location where the 24' impact points actually are. This allows, for example, the stride length to be calculated in real time and displayed, as well as the maximum achieved knee flexion angle in the upper left corner.

[0063] Furthermore, the entry into a special mode of the prosthesis 30, for example the stumbling detection, can be visualized at a later time by means of a corresponding symbol.

[0064] The data can come from the prosthesis itself, be determined by the reality augmentation device itself (e.g., stride length), or come from external sensors.

[0065] Figure 5 shows an embodiment in which the patient 200 walks up a ramp 300 in the field of view of the orthotist. However, the prosthesis 30 mistakenly detects a staircase and switches to the corresponding staircase mode, which is transmitted as status-related data of the prosthesis 30 to the reality augmentation device. The reality augmentation device displays the staircase mode in the form of a virtual staircase 310, whereby the orthotist immediately recognizes that the prosthesis 30 is in the wrong mode. This facilitates troubleshooting. Finally, Figure 6 shows an example in which a movement sequence of a patient 200 is superimposed. In this case, another additional movement sequence 200' is displayed in the orthotist's field of view, which, for example, was previously recorded as a virtual twin or artificially generated from corresponding data. The technician can thus compare and understand the effect of the last changes to the prosthesis.A comparison with previously recorded data from the same patient can be performed, physiologically ideal data can be displayed, and / or a simulation of the expected movement can be presented. The reality augmentation device can be supported by an additional camera 14 as an external sensor.

[0066] In the embodiment of Figure 6, the augmentation of reality is also shown using a tablet 15. The camera of the tablet 15 is directed at the patient 200 and records their movements. The movement of the patient 200 recorded by the camera of the tablet 15 is then immediately shown on the display and enhanced with the corresponding information.
