[0028] Among them, it should be noted that the executor of the gait correction effect evaluation method of the ankle-foot orthosis of this embodiment is the gait correction effect evaluation device of the ankle-foot orthosis, which can be implemented by software and / or hardware, and 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.

[0029] like Figure 1 As shown, the method for evaluating the gait correction effect of the ankle-foot orthosis includes:

[0030] S101: Obtaining gait parameters of a target user after wearing an ankle-foot orthosis, wherein the target user has symptoms of abnormal ankle-foot posture.

[0031] The target user may refer to a user who has abnormal ankle and foot posture symptoms in the embodiment of the present disclosure.

[0032] The gait parameters may be used to describe the posture characteristics of the target user during walking, such as step length, stride frequency, etc., without limitation.

[0033] That is to say, in the embodiments of the present disclosure, gait parameter detection can be performed on the target user, and then the gait parameters can be obtained as data support for the subsequent gait correction effect of the orthosis.

[0034] In the embodiment of the present disclosure, when obtaining the gait parameters of the target user after wearing the ankle-foot orthosis, a corresponding sensor device may be configured based on the type of parameters to be obtained, and the corresponding gait parameters may be obtained through the sensor device.

[0035] S102: Calculate symmetry feature parameters of the target user according to the gait parameters, wherein the symmetry feature parameters are used to describe the left-right symmetry of the target user's gait.

[0036] Among them, the symmetry feature parameter can be used to indicate whether the gait of the target user on the left and right sides during walking is symmetrical.

[0037] In the embodiment of the present disclosure, when calculating the symmetry characteristic parameters of the target user based on the gait parameters, the walking posture of the target user can be digitally modeled based on the gait parameters, and then the symmetry characteristic parameters can be determined by comparing the left and right mirror images. Alternatively, the symmetry characteristic parameters of the target user can be calculated based on the gait parameters based on any other possible method, and there is no limitation to this.

[0038] That is to say, in the embodiment of the present disclosure, after obtaining the gait parameters of the target user after wearing the ankle-foot orthosis, the symmetry characteristic parameters of the target user can be calculated based on the gait parameters, thereby providing reference information of the symmetry dimension for the subsequent generation of gait correction evaluation results.

[0039] S103: Calculate stability characteristic parameters of the target user according to the gait parameters, wherein the stability characteristic parameters are used to describe the stability of the gait of the target user.

[0040] Among them, the stability characteristic parameter can be used to describe whether the walking posture of the target user is stable over a period of time.

[0041] That is to say, in the embodiment of the present disclosure, after obtaining the gait parameters of the target user after wearing the ankle-foot orthosis, the stability characteristic parameters of the target user can be calculated based on the gait parameters, thereby providing reference information of the gait stability dimension for the subsequent generation of gait correction evaluation results.

[0042] S104: Generate a gait correction evaluation result according to the symmetry characteristic parameter and the stability characteristic parameter.

[0043] Among them, the gait correction assessment results can be used to indicate the correction effect of ankle-foot orthosis.

[0044] It can be understood that in the embodiment of the present disclosure, the gait correction evaluation result is positively correlated with the user's gait symmetry and stability. When the symmetry characteristic parameters and the stability characteristic parameters indicate that the target user's gait symmetry and stability are better, the correction effect of the corresponding ankle-foot orthosis is better.

[0045] In the disclosed embodiment, when generating a gait correction evaluation result according to the symmetry characteristic parameters and the stability characteristic parameters, it may be based on a pre-configured relationship table, which contains evaluation results corresponding to the symmetry characteristic parameters and the stability characteristic parameters.

[0046] In the disclosed embodiment, when a gait correction evaluation result is generated based on symmetry characteristic parameters and stability characteristic parameters, the resulting gait correction effect can be described from two dimensions, symmetry and stability, thereby effectively improving the practicality and clarity of indication of the resulting gait correction effect.

[0047] In this embodiment, the gait parameters of the target user after wearing the ankle-foot orthosis are obtained, wherein the target user has symptoms of abnormal ankle-foot posture; according to the gait parameters, the symmetry characteristic parameters of the target user are calculated, wherein the symmetry characteristic parameters are used to describe the left-right symmetry of the target user's gait; according to the gait parameters, the stability characteristic parameters of the target user are calculated, wherein the stability characteristic parameters are used to describe the stability of the target user's gait; according to the symmetry characteristic parameters and the stability characteristic parameters, a gait correction evaluation result is generated. Thus, the symmetry characteristic parameters and the stability characteristic parameters of the target user after wearing the ankle-foot orthosis can be combined to objectively and accurately realize the quantitative evaluation of the gait correction effect of the ankle-foot orthosis on the target user, thereby effectively improving the practicality of the obtained gait correction evaluation result.

[0052] S202: Determine a first parameter and a second parameter from the gait parameters, wherein the first parameter is used to describe the gait characteristics of the left side of the target user, and the second parameter is used to describe the gait characteristics of the right side of the target user.

[0053] The types of the first parameter and the second parameter can be flexibly selected according to the application scenario, and there is no restriction on this.

[0054] Optionally, in some embodiments,

[0055] When the first parameter is the distance parameter of the left supporting phase, the second parameter is the distance parameter of the right supporting phase;

[0056] When the first parameter is the duration of the left stance phase, the second parameter is the duration of the right stance phase.

[0057] The support phase refers to the process in which the lower limbs touch the ground and bear the body's gravity when walking, while the left support phase and the right support phase refer to the support phases corresponding to the left lower limb and the right lower limb, respectively.

[0058] That is to say, the gait parameters in the disclosed embodiment may include a variety of related parameters, and in the process of calculating the symmetry feature parameters, the first parameter and the second parameter may be determined from the gait parameters as analysis objects according to the scenario requirements, thereby ensuring that the calculation process is adapted to the personalized application scenario.

[0059] S203: Determine a ratio of the first parameter to the second parameter as a symmetry characteristic parameter.

[0060] Optionally, in some embodiments, the difference between the first parameter and the second parameter may be determined as the symmetry characteristic parameter, or any other parameter corresponding to the first parameter and the second parameter may be determined as the symmetry characteristic parameter, without limitation.

[0061] In the disclosed embodiment, multiple parameter pairs can be selected, different parameter pairs include different types of first parameters and second parameters, and then the ratios corresponding to the different parameter pairs are calculated respectively, and finally the symmetry characteristic parameters are determined in combination with the ratios of the different parameter pairs (for example, the ratios corresponding to all parameter pairs can be used as symmetry characteristic parameters, or the symmetry characteristic parameters can be obtained by weighted summing up the ratios corresponding to all parameter pairs, and there is no limitation on this).

[0062] That is, in the embodiment of the present disclosure, after obtaining the gait parameters of the target user after wearing the ankle-foot orthosis, the first parameter and the second parameter can be determined from the gait parameters, wherein the first parameter is used to describe the gait characteristics of the left side of the target user, and the second parameter is used to describe the gait characteristics of the right side of the target user; the ratio of the first parameter and the second parameter is determined as the symmetry characteristic parameter.

[0068] distance parameter of the right support phase;

[0069] Duration of the left support phase;

[0070] Duration of the right support phase;

[0071] Duration of the double support phase.

[0072] In this way, it can be ensured that the third parameter can be applicable to personalized application scenarios.

[0073] Among them, the double support phase refers to the process of the two feet supporting the body when walking, that is, the stage in the walking cycle when both legs touch the ground at the same time.

[0074] That is, in the embodiment of the present disclosure, after obtaining the gait parameters of the target user after wearing the ankle-foot orthosis, the third parameter can be determined from the gait parameters according to the application scenario as the object of subsequent gait stability analysis.

[0075] S205: Determine a plurality of consecutive sampling values ​​of a third parameter.

[0076] The sampling value refers to the value obtained by sampling the third parameter of the target user during walking.

[0077] That is, in the embodiment of the present disclosure, after the third parameter is determined, continuous sampling can be performed on the third parameter, and then the change of the third parameter over time can be determined, providing reliable data support for the subsequent calculation of the stability characteristic parameter.

[0078] S206: Based on a plurality of continuous sampling values, calculate and obtain stability characteristic parameters.

[0079] For example, in the embodiments of the present disclosure, when calculating the stability characteristic parameter based on multiple continuous sampling values, the range values ​​of the multiple sampling values ​​may be calculated as the stability characteristic parameter, or the standard deviation, moving average, moving standard deviation, etc. of the multiple sampling values ​​may be calculated, without limitation.

[0080] Optionally, in some embodiments, when calculating the stability characteristic parameter based on a plurality of consecutive sampling values, the variance of the plurality of consecutive sampling values ​​may be calculated as the stability characteristic parameter, thereby ensuring the clarity and accuracy of the indication of the stability characteristic parameter on gait stability.

[0081] That is, in the embodiment of the present disclosure, after obtaining the gait parameters of the target user wearing the ankle-foot orthosis, the third parameter can be determined from the gait parameters, wherein the third parameter is used to describe the gait characteristics of the target user; a plurality of continuous sampling values ​​of the third parameter are determined; and a stability characteristic parameter is calculated based on the plurality of continuous sampling values. Thus, it can be ensured that the stability characteristic parameter calculation process is suitable for personalized application scenarios, and the clarity of the indication of the obtained characteristic stability parameter is effectively improved.

[0082] S207: Generate a gait correction evaluation result according to the symmetry characteristic parameter and the stability characteristic parameter.

[0083] The description of S207 can be specifically referred to the above embodiment, which will not be repeated here.

By determining the third parameter from the gait parameters, wherein the third parameter is used to describe the gait characteristics of the target user; determining multiple continuous sampling values ​​of the third parameter; and calculating the stability characteristic parameter based on the multiple continuous sampling values. In this way, it can be ensured that the stability characteristic parameter calculation process is suitable for personalized application scenarios, and the clarity of the indication of the obtained characteristic stability parameter is effectively improved.
