[0028] Figure 1 1 is a flow chart of a method for evaluating the correction effect of an ankle-foot orthosis on abnormal plantar stress, according to an embodiment of the present disclosure.

[0029] Among them, it should be noted that the executor of the method for evaluating the corrective effect of the ankle-foot orthosis on abnormal plantar force in this embodiment is the device for evaluating the corrective effect of the ankle-foot orthosis on abnormal plantar force, which can be implemented by software and / or hardware. The device can be configured in a computer device, and the computer device can include but is not limited to a terminal, a server, etc. For example, the terminal can be a mobile phone, a handheld computer, etc.

[0030] like Figure 1 As shown, the method for evaluating the correction effect of the ankle-foot orthosis on abnormal plantar force includes:

[0031] S101: Obtain target pressure detection data of multiple plantar locations of a target user, wherein the target user has symptoms of abnormal plantar force and wears an ankle-foot orthosis.

[0032] The target user may refer to a user who has abnormal ankle and foot force patterns such as pointed feet, inversion, and eversion and who has worn an ankle-foot orthosis in the embodiment of the present disclosure.

[0033] The plantar site refers to the location on the sole of the target user's foot where pressure testing is required. The selection of the plantar site can be flexibly adjusted according to the user's symptoms and scenario requirements, and there is no restriction on this.

[0034] Optionally, in some embodiments, multiple plantar locations include: first phalanx; third phalanx; fifth phalanx; first metatarsal; fifth metatarsal; medial anterior arch; lateral anterior arch; middle arch; middle heel.

[0035] The target pressure detection data refers to the data obtained after pressure detection of the soles of the target user in the embodiment of the present disclosure.

[0036] The abnormal plantar stress symptoms may include, for example, tiptoe, inversion, valgus, or any other abnormal plantar stress symptoms, without limitation.

[0037] That is, in the embodiment of the present disclosure, target pressure detection data of multiple plantar sites of the target user can be obtained, thereby providing reliable data support for subsequent correction effect evaluation.

[0038] S102: Generate a target pressure change curve corresponding to the plantar site according to the target pressure detection data.

[0039] The target pressure change curve may be used to describe how the target pressure detection data corresponding to the plantar site changes over time.

[0040] In the embodiment of the present disclosure, a software program may draw and display a pressure data curve based on the target pressure detection data as the target pressure change curve.

[0041] That is to say, in the embodiment of the present disclosure, after obtaining the target pressure detection data, a method combining numbers and shapes can be used to generate a target pressure change curve corresponding to the plantar site based on the target pressure detection data, thereby providing clear and reliable reference information for the subsequent extraction of characteristic parameters of the plantar pressure curve.

[0042] S103: Extracting characteristic parameters of the plantar pressure curve according to the target pressure change curve.

[0043] The characteristic parameters of the plantar pressure curve refer to the parameters determined after feature extraction of the target pressure change curve in the embodiment of the present disclosure. The type of the characteristic parameters of the plantar pressure curve can be flexibly adjusted according to the application scenario and is not limited thereto.

[0044] Optionally, in some embodiments, the characteristic parameter of the plantar pressure curve includes at least one of the following:

[0045] The start and end time of pressure generation;

[0046] How long the stress lasts;

[0047] Peak occurrence time;

[0048] The area enclosed by the target pressure change curve and the coordinate axis;

[0049] Timing information of the start and end of plantar pressure at different locations;

[0050] The ratio of plantar pressure at the same force point.

[0051] Among them, the starting and ending timing information of the plantar pressure at different sites can be used to describe the order of the generation and end of the plantar pressure at different sites in the time dimension.

[0052] Among them, the ratio value of the plantar pressure at the same force-bearing points can be used to indicate the size relationship of the pressure detection values ​​of multiple force-bearing points at the same time point.

[0053] That is to say, in the embodiment of the present disclosure, after generating the target pressure change curve corresponding to the plantar site based on the target pressure detection data, the target pressure change curve can be feature extracted, and then the characteristic parameters of the plantar pressure curve can be extracted to provide reliable reference information for subsequent correction effect evaluation.

[0054] S104: Evaluate the correction effect according to the characteristic parameters of the plantar pressure curve to obtain an evaluation result.

[0055] The evaluation results can be used to indicate the corrective effect of the ankle-foot orthosis on the abnormal force symptoms on the soles of the target users.

[0056] In the embodiment of the present disclosure, when evaluating the correction effect based on the characteristic parameters of the plantar pressure curve to obtain the evaluation result, the characteristic parameters of the plantar pressure curve can be input into a pre-trained machine learning model to determine the corresponding evaluation result, or, the correction effect can be evaluated based on the characteristic parameters of the plantar pressure curve based on a method combining numbers and shapes to obtain the evaluation result, and there is no limitation on this.

[0057] In this embodiment, target pressure detection data is obtained from multiple plantar sites of a target user, where the target user has symptoms of abnormal plantar force and is wearing an ankle-foot orthosis (AFO). Based on the target pressure detection data, a target pressure change curve corresponding to each plantar site is generated. Based on the target pressure change curve, characteristic parameters of the plantar pressure curve are extracted. Finally, the correction effect is evaluated based on the characteristic parameters of the plantar pressure curve to obtain an evaluation result. Thus, based on the pressure detection data from the plantar of the user wearing the AFO, the correction effect of the AFO can be objectively and accurately evaluated, thereby providing reliable reference information for the optimization of the AFO.

[0058] Figure 2 It is a flowchart of a method for evaluating the correction effect of an ankle-foot orthosis on abnormal plantar stress, proposed in another embodiment of the present disclosure.

[0059] like Figure 2 As shown, the method for evaluating the correction effect of the ankle-foot orthosis on abnormal plantar force includes:

[0060] S201: Obtain target pressure detection data of multiple plantar locations of a target user, wherein the target user has symptoms of abnormal plantar force and wears an ankle-foot orthosis.

[0061] S202: Generate a target pressure change curve corresponding to the plantar site according to the target pressure detection data.

[0062] S203: Extracting characteristic parameters of the plantar pressure curve according to the target pressure change curve.

[0063] The description of S201 - S203 can be found in the above embodiment and will not be repeated here.

[0064] S204: Acquire reference characteristic parameters corresponding to the characteristic parameters of the plantar pressure curve.

[0065] The reference characteristic parameter may refer to a characteristic parameter of the same type as the plantar pressure curve characteristic parameter and used as a reference benchmark.

[0066] In the embodiment of the present disclosure, when obtaining reference characteristic parameters corresponding to the characteristic parameters of the plantar pressure curve, a data link between the execution entity of the embodiment of the present disclosure and the big data center can be established in advance, and then applicable reference characteristic parameters can be obtained from the big data center (which can be selected in combination with the target user's age, gender, height, weight and other characteristics). Alternatively, reference characteristic parameters corresponding to the characteristic parameters of the plantar pressure curve can be obtained based on other methods, and there is no limitation on this.

[0067] Optionally, in some embodiments, reference pressure measurement data can be obtained for multiple plantar sites of a reference user, where the reference user does not experience abnormal plantar force symptoms and does not wear an ankle-foot orthosis. Based on the reference pressure measurement data, a reference pressure change curve corresponding to each plantar site is generated. Reference characteristic parameters are determined based on the reference pressure change curve. This ensures the applicability of the obtained reference characteristic parameters.

[0068] The term "reference user" refers to a user who does not experience abnormal plantar stress and does not wear an ankle-foot orthosis. In the disclosed embodiments, when selecting reference users, the user's age, gender, height, weight, and other characteristics may be considered, with users who have similar characteristics to the target user being selected as reference users.

[0069] The reference stress detection data refers to the stress detection data obtained by performing the same stress detection process on a reference user as that on the target user.

[0070] The reference pressure variation curve may be used to describe how the reference pressure detection data varies over time.

[0071] The reference characteristic parameter refers to the characteristic parameter determined by extracting the characteristics of the reference pressure change curve. The type and acquisition method of the reference characteristic parameter in the embodiment of the present disclosure can refer to the acquisition method of the characteristic parameter of the plantar pressure curve described above, which will not be repeated here.

[0072] That is, in the embodiment of the present disclosure, after extracting the characteristic parameters of the plantar pressure curve according to the target pressure change curve, reference characteristic parameters corresponding to the characteristic parameters of the plantar pressure curve can be obtained, thereby providing reliable reference data for subsequent correction effect evaluation.

[0073] S205: Determine a first comparison result between the characteristic parameters of the plantar pressure curve and the reference characteristic parameters.

[0074] The first comparison result refers to the comparison result between the characteristic parameter of the plantar pressure curve and the reference characteristic parameter, and can be used to indicate the magnitude relationship between the characteristic parameter of the plantar pressure curve and the reference characteristic parameter, for example.

[0075] In the embodiment of the present disclosure, when determining the first comparison result between the characteristic parameter of the plantar pressure curve and the reference characteristic parameter, reliable reference information can be provided for the subsequent determination of the evaluation result.

[0076] S206: Determine an evaluation result based on the first comparison result.

[0077] In the embodiment of the present disclosure, when determining the evaluation result based on the first comparison result, it can be based on a pre-configured relationship table, which contains the evaluation result corresponding to the first comparison result, or it can be based on a third-party evaluation device, which is not limited to this.

[0078] Optionally, in some embodiments, when determining the evaluation result based on the first comparison result, the following steps may be performed: obtaining initial pressure measurement data for multiple plantar sites of the target user when the user is not wearing an AFO; generating initial pressure change curves corresponding to the plantar sites based on the initial pressure measurement data; determining initial characteristic parameters based on the initial pressure change curves; determining a second comparison result between the characteristic parameters of the plantar pressure curve and the initial characteristic parameters; and determining the evaluation result based on the first and second comparison results. Thus, the pressure measurement data of the target user when the user is not wearing an AFO can be incorporated into the evaluation process to ensure the adaptability and accuracy of the evaluation result to the target user.

[0079] The initial pressure detection data refers to the pressure detection data of multiple plantar sites when the target user is not wearing an ankle-foot orthosis.

[0080] The initial pressure change curve refers to a pressure change curve generated based on the initial pressure detection data, and can be used to indicate changes in the initial pressure detection data over time.

[0081] The initial characteristic parameter refers to the characteristic parameter determined by extracting the characteristics of the initial pressure change curve. The type of the initial characteristic parameter can be consistent with the type of the characteristic parameter of the plantar pressure curve.

[0082] The second comparison result may be used to indicate a comparison between the characteristic parameters of the plantar pressure curve and the initial characteristic parameters.

[0083] Specifically, in the disclosed embodiments, a reference characteristic parameter corresponding to a plantar pressure curve characteristic parameter can be obtained; a first comparison result between the plantar pressure curve characteristic parameter and the reference characteristic parameter can be determined; and an evaluation result can be determined based on the first comparison result. Thus, the reference characteristic parameter can be incorporated into the evaluation process to ensure accuracy and reliability.

[0084] In this embodiment, a reference characteristic parameter corresponding to the plantar pressure curve characteristic parameter is obtained; a first comparison result between the plantar pressure curve characteristic parameter and the reference characteristic parameter is determined; and an evaluation result is determined based on the first comparison result. Thus, the reference characteristic parameter can be incorporated into the evaluation process to ensure accuracy and reliability of the evaluation process.

[0085] Based on the above embodiments, the present disclosure can design an ankle-foot orthosis correction effect evaluation system, which can record the plantar pressure parameters in real time during the wearing of the ankle-foot orthosis, calculate and analyze the spatial distribution of plantar pressure and its change pattern over time through an algorithm, so as to evaluate the degree to which the ankle-foot orthosis regulates and improves abnormal plantar stress conditions such as pointed feet, inversion, and eversion. The system includes multi-channel pressure detection sensors distributed on the sole of the foot, signal conditioning circuits, signal transmission and interface circuits, plantar pressure data analysis algorithms and software programs. Figure 3 As shown, Figure 3This is a schematic diagram of the structure of the ankle-foot orthosis correction effect evaluation system proposed in the present disclosure. By recording the plantar pressure of the first toe, third toe, fifth toe, first metatarsal, fifth metatarsal, medial anterior arch, lateral anterior arch, middle arch, and middle heel, a plantar pressure change curve is generated. The algorithm is used to measure the start and end time and duration of plantar pressure at different sites, the peak time of plantar pressure, the area enclosed by the plantar pressure curve, the temporal relationship between the start and end of plantar pressure at different sites, and the proportional relationship between plantar pressure at the same stress site. Then, the time parameters and amplitude parameters of the plantar pressure at the first toe, third toe, fifth toe, first metatarsal, fifth metatarsal, medial anterior arch, lateral anterior arch, middle arch, and middle heel during normal walking are used as a benchmark. The differences in the above characteristic parameters are compared through a comparison algorithm, which serves as a basis for doctors to judge whether the orthosis can improve and regulate the time and spatial distribution characteristics of plantar force.

[0086] Figure 4 Schematic diagram of the structure of an apparatus for evaluating the correction effect of an ankle-foot orthosis on abnormal plantar stress, according to one embodiment of the present disclosure.

[0087] like Figure 4 As shown, the device 40 for evaluating the correction effect of the ankle-foot orthosis on abnormal plantar stress includes:

[0088] An acquisition module 401 is configured to acquire target pressure detection data of multiple plantar locations of a target user, wherein the target user has symptoms of abnormal plantar force and wears an ankle-foot orthosis;

[0089] A generating module 402 is configured to generate a target pressure change curve corresponding to a plantar site based on the target pressure detection data;

[0090] A determination module 403 is used to extract characteristic parameters of the plantar pressure curve according to the target pressure change curve;

[0091] The evaluation module 404 is used to evaluate the correction effect according to the characteristic parameters of the plantar pressure curve to obtain an evaluation result.

[0092] It should be noted that the aforementioned explanation of the method for evaluating the correction effect of the ankle-foot orthosis on abnormal plantar force is also applicable to the apparatus for evaluating the correction effect of the ankle-foot orthosis on abnormal plantar force in this embodiment, and will not be repeated here.

[0093] In this embodiment, target pressure detection data is obtained from multiple plantar sites of a target user, where the target user has symptoms of abnormal plantar force and is wearing an ankle-foot orthosis (AFO). Based on the target pressure detection data, a target pressure change curve corresponding to each plantar site is generated. Based on the target pressure change curve, characteristic parameters of the plantar pressure curve are extracted. Finally, the correction effect is evaluated based on the characteristic parameters of the plantar pressure curve to obtain an evaluation result. Thus, based on the pressure detection data from the plantar of the user wearing the AFO, the correction effect of the AFO can be objectively and accurately evaluated, thereby providing reliable reference information for the optimization of the AFO.
