Technical Field
[0001] This invention relates to the field of intelligent rehabilitation devices, and in particular to an adaptive movement method and system based on an intelligent rehabilitation device. Background Technology
[0002] Intelligent rehabilitation devices refer to auxiliary equipment that integrates sensor technology, drive control, and human-computer interaction to help users conduct scientific and effective rehabilitation training.
[0003] Currently, existing rehabilitation devices have basic motion data acquisition capabilities. Some products can collect single-dimensional information such as joint angles and movement speeds from users through sensors, and perform simple monitoring of the movement process based on preset fixed thresholds.
[0004] However, existing devices rely on a single evaluation index when judging movement status, which cannot extract movement characteristics from multiple dimensions. They also do not consider the differences in movement needs at different stages of rehabilitation training. They can only judge the movement process according to a uniform standard, which is difficult to adapt to the actual movement status of users at different stages and needs to be improved. Summary of the Invention
[0005] To adapt to the actual movement status of users at different stages, this invention provides an adaptive movement method and system based on an intelligent rehabilitation device.
[0006] In a first aspect, the present invention provides an adaptive exercise method based on an intelligent rehabilitation device, employing the following technical solution: An adaptive exercise method based on an intelligent rehabilitation device includes: Collect biomechanical data; Multidimensional motion features are extracted from biomechanical data and combined with a pre-set multi-stage standard motion template library to obtain the current motion state; Identify the current motion stage based on the current motion state; Based on the current stage of the movement, the corresponding standard movement template is matched from the multi-stage standard movement template library; Combine the current motion state with a standard motion template to obtain the risk value of deviation from the motion parameters; When the motion parameters deviate from the risk value beyond the preset risk threshold, a motion adjustment strategy is generated based on the standard motion template and the deviation of the motion parameters from the risk value. Based on motion adjustment strategies, adaptive motion regulation is performed on intelligent rehabilitation devices.
[0007] By employing the above technical solution, biomechanical data is first collected to extract multidimensional movement features. Combined with a multi-stage standard movement template library, the user's current movement state and rehabilitation stage are determined. Subsequently, a standard movement template corresponding to the stage is matched, and the deviation risk value of movement parameters is calculated by comparing the current movement state with the template. When the risk value exceeds the limit, a targeted movement adjustment strategy is generated based on the template and the risk value, and the control device executes adaptive adjustment. This approach comprehensively reflects the user's movement state through multidimensional features and adapts to the different needs of different rehabilitation stages through staged template matching, ensuring a better fit for the actual movement state of users at different stages.
[0008] Optionally, it may also include the specific implementation steps for generating the motion adjustment strategy: Collect user physiological indicators and current environmental parameters; A comprehensive feature space is generated by combining user physiological indicators, current environmental parameters, and biomechanical data. Determine the parameter adjustment dimension based on the comprehensive feature space; The feature deviation value is obtained based on the multidimensional motion features and the standard motion features extracted from the standard motion template. The motion adjustment strategy is generated by combining feature deviation values, motion parameter deviation risk values, parameter adjustment dimensions, and a preset evaluation function.
[0009] By employing the aforementioned technical solution, user physiological indicators and current environmental parameters are collected and integrated to construct a comprehensive feature space. Based on this comprehensive feature space, the parameter adjustment dimensions are precisely determined. Then, by comparing multi-dimensional movement features with standard movement features to obtain feature deviation values, and combining these with movement parameter deviation risk values, adjustment dimensions, and preset evaluation functions, a scientific movement adjustment strategy is calculated and generated. This approach avoids the one-sidedness of strategies caused by single data sources through multi-data fusion, and ensures that the strategy aligns with the user's current physiological tolerance through precise adjustment dimension positioning and a scientific evaluation function. Ultimately, it achieves more personalized and safer adaptive adjustment, further adapting to the actual movement needs of users at different stages and in different physical states.
[0010] Optional, also includes: Collect user electromyography signals, heart rate variability, and exercise speed decay rate; Fatigue level values are generated based on user electromyography signals, heart rate variability, and exercise speed decay rate. When the fatigue level value exceeds the preset fatigue level safety threshold, the fatigue exceedance value is obtained based on the fatigue level value and the fatigue level safety threshold. The target adjustment range is determined based on the fatigue exceedance value; The motion adjustment strategy is modified by adjusting the target amplitude to generate a safe motion adjustment strategy; The intelligent rehabilitation device reduces exercise load based on a safe exercise adjustment strategy.
[0011] By employing the aforementioned technical solution, the system first collects the user's electromyography (EMG) signals, heart rate variability, and exercise speed decay rate. Based on the fusion of these three data points, a quantified fatigue level value is calculated to accurately determine whether the user is in a state of excessive fatigue. When the fatigue level value exceeds a safe threshold, the system calculates the excess fatigue value to determine the target adjustment range for reducing the exercise load. This range is then used to modify the original exercise adjustment strategy, generating a safe exercise adjustment strategy that prioritizes user safety. Ultimately, the system controls the intelligent rehabilitation device to perform the load reduction operation. This avoids the risk of training injuries caused by focusing solely on adjusting exercise parameters while neglecting user fatigue, and further adapts to the actual exercise needs of users under different fatigue states.
[0012] Optional, wearable recognition methods may also be included: Collect exercise resistance values and rehabilitation device models; The standard resistance value is obtained based on the model of the rehabilitation device and the current stage of exercise; A standard resistance range is generated based on the standard resistance value and the preset resistance range value; When the resistance value exceeds the standard resistance range, the wearing adjustment is performed using the preset wearing adjustment method.
[0013] By adopting the above technical solution, real-time exercise resistance values and rehabilitation device model are first collected, and the corresponding standard resistance value is retrieved from preset data based on the current exercise stage. Then, a standard resistance range is generated based on the standard resistance value and preset resistance range values, which serves as the basis for judging whether the wearing is appropriate. When the real-time exercise resistance value exceeds this range, the system initiates the wearing adjustment method to adjust the wearing, avoiding the impact of improper wearing on the accuracy of exercise data collection or causing user discomfort, further ensuring the effectiveness and comfort of rehabilitation training, and indirectly improving the accuracy of exercise adjustment strategies.
[0014] Optionally, the wearing adjustment method includes: Combine the motion resistance value with the standard resistance range to generate a resistance difference value; The wearing difference rate is derived based on the resistance difference value; Determine whether the wearing difference rate exceeds the preset adjustment difference rate; When the wearing difference rate exceeds the adjustment difference rate, a prompt to stop using the device should be reported; When the wearing difference rate does not exceed the adjustment difference rate, the intelligent rehabilitation device will automatically adjust itself using a preset automatic adjustment method.
[0015] By adopting the above technical solution, a resistance difference value is first generated by comparing the exercise resistance value with the standard resistance range, and then the wearing difference rate is calculated. Then, based on the adjustment difference rate as a threshold, wearing abnormalities are graded and handled: when the wearing difference rate exceeds the adjustment difference rate, a stop-use prompt is immediately reported to avoid forced training causing damage to the user or aggravating device abnormalities; when the difference rate does not exceed the threshold, the automatic adjustment method is activated to allow the device to correct its wearing status automatically. This not only prevents the automatic adjustment function from operating ineffectively in cases of severe abnormalities, but also achieves automatic optimization of the wearing status within a safe range, reducing the tediousness of manual adjustment by the user and ensuring that the rehabilitation device always participates in training with a suitable fit.
[0016] Optionally, the automatic adjustment method includes: Collect user recovery plans; The subsequent exercise phase is determined based on the user's recovery plan and current exercise phase. The motion parameters of the device are obtained based on the subsequent motion stages; Based on the wearing difference rate and device motion parameters, the fixation device offset parameters are generated; The device adjustment parameters are generated by combining the device offset parameters, wearing difference rate, and device motion parameters. The intelligent rehabilitation device is controlled to continue exercising according to the user's recovery plan, while the preset wearing adjustment device is controlled to operate according to the device adjustment parameters.
[0017] By employing the above technical solution, the user's complete recovery plan is first collected, and the subsequent exercise stages are predicted based on the current exercise stage. The corresponding device motion parameters are then determined according to the needs of the subsequent stages. Based on this, the device offset parameters are generated by combining the real-time calculated wearing difference rate with the device motion parameters for the subsequent stages. Then, the offset parameters, wearing difference rate, and current device motion parameters are integrated to generate device adjustment parameters that balance current wearing correction with adaptation for the subsequent stages. Finally, the rehabilitation device is controlled to continue training according to the recovery plan, while simultaneously driving the wearing adjustment device to operate according to the adjustment parameters. This not only solves the problem of motion resistance deviation caused by current wearing abnormalities but also prepares for the device parameter requirements of the subsequent exercise stages in advance, avoiding the problem of repeated device adjustments during training stages.
[0018] Optionally, the method of operating the adjustment device also includes: The driving amplitude value is obtained by adjusting the device parameters. The device contact strength value is generated based on the driving amplitude value; The airbag inflation volume is determined by measuring the contact strength of the device. Based on the airbag inflation volume, the preset inflation airbag is inflated to establish a physical contact state between the wearing adjustment device and the intelligent rehabilitation device. While maintaining physical contact, the intelligent rehabilitation device is controlled to move according to the user's recovery plan, thereby driving the wearing adjustment device to adjust its fit.
[0019] By adopting the above technical solution, the specific driving amplitude value is first determined based on the device's adjustment parameters. Then, the contact strength value between the device and the human body is calculated based on this amplitude value, and the strength value is converted into the corresponding airbag inflation volume. By quantitatively inflating the airbag, a stable physical contact state is formed between the wearing adjustment device, the intelligent rehabilitation device, and the human body. While maintaining this contact state, the rehabilitation device continues to move according to the user's recovery plan. Utilizing the relative displacement between the device and the human body during movement, the wearing adjustment device naturally completes the wearing adjustment, thus balancing the stability of the adjustment and the user's comfort. At the same time, the adjustment process is integrated into normal training exercises, avoiding interruptions caused by separate shutdowns for adjustment. This ensures the continuity of training while making the adjusted wearing state more closely match the actual exercise needs, further improving the wearing adaptability and user experience of the intelligent rehabilitation device during dynamic training.
[0020] Optional, also includes: Collect user facial expression data and voice feedback information; Generate a user's emotional state assessment value based on user facial expression data and voice feedback information; Combine user emotional state assessment values and fatigue level values to generate a comprehensive user experience index; The training comfort evaluation results are obtained based on comprehensive user experience metrics; The safe exercise adjustment strategy is optimized based on the training comfort assessment results, and the exercise parameters of the intelligent rehabilitation device are adjusted based on the optimized safe exercise adjustment strategy.
[0021] Optional, also includes: An exercise quality score is generated based on training comfort assessment results and risk values of deviation from exercise parameters; Collect user electromyography signal recovery rate, joint range of motion improvement indicators, and user recovery plan; The exercise effect value is generated by combining exercise quality score, electromyographic signal recovery rate and joint range of motion improvement index. An optimized recovery plan is generated based on the exercise effect value and the user's recovery plan, and training is planned according to the optimized recovery plan.
[0022] Secondly, this application provides an adaptive motion system based on an intelligent rehabilitation device, employing the following technical solution: An adaptive motion system based on an intelligent rehabilitation device includes: The data acquisition module is used to collect biomechanical data; A memory for storing a program that implements an adaptive movement method based on an intelligent rehabilitation device; The processor is used to load and execute programs stored in memory.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By first collecting biomechanical data and extracting multidimensional movement features, and combining this with a multi-stage standard movement template library, the system determines the user's current movement status and identifies their rehabilitation stage. Then, it matches the corresponding standard movement template to the stage and calculates the risk value of movement parameter deviation by comparing the current movement status with the template. When the risk value exceeds the limit, a targeted movement adjustment strategy is generated based on the template and the risk value, and the control device performs adaptive adjustment. This approach comprehensively reflects the user's movement status through multidimensional features and adapts to the different needs of different rehabilitation stages through staged template matching, ensuring a better fit for the actual movement status of users at different stages. 2. First, a resistance difference value is generated by comparing the exercise resistance value with the standard resistance range, and then the wearing difference rate is calculated. Then, based on the adjustment difference rate as a threshold, wearing abnormalities are graded and handled: when the wearing difference rate exceeds the adjustment difference rate, a stop-use prompt is immediately reported to avoid forced training causing damage to the user or aggravating device abnormalities; when the difference rate does not exceed the threshold, the automatic adjustment method is activated to allow the device to correct its wearing status automatically. This not only prevents the automatic adjustment function from operating ineffectively in cases of severe abnormalities, but also achieves automatic optimization of the wearing status within a safe range, reducing the tediousness of manual adjustment by the user and ensuring that the rehabilitation device always participates in training with an appropriate fit. 3. By first collecting the user's complete recovery plan, predicting subsequent exercise stages based on the current stage, and determining the corresponding device motion parameters according to the needs of the subsequent stages, the system generates fixed device offset parameters by combining the real-time calculated wearing difference rate with the device motion parameters of the subsequent stages. Then, by integrating the offset parameters, wearing difference rate, and current device motion parameters, device adjustment parameters that balance current wearing correction with adaptation for the subsequent stages are generated. Finally, the rehabilitation device is controlled to continue training according to the recovery plan, while simultaneously driving the wearing adjustment device to operate according to the adjustment parameters. This not only solves the motion resistance deviation caused by current wearing abnormalities but also prepares for the device parameter requirements of subsequent exercise stages in advance, avoiding the problem of repeatedly adjusting the device during training stages.

These are ultimately integrated into a multidimensional feature set including "joint biomechanical features, plantar pressure features, and trunk balance features," thus obtaining the multidimensional motion features. The specific 15 statistical features are pre-defined by those skilled in the art and will not be elaborated upon here.

[0037] The current motion stage can be found by looking up the core features of the current motion state through the preset stage comparison table. The table records the different core features corresponding to different motion stages. The comparison content in the stage comparison table is preset by those skilled in the art to form the different core features corresponding to different motion stages, which will not be elaborated here.

The specific implementation steps of the motion adjustment strategy will be explained in detail in S20 to S24, and will not be repeated here.
[0049] When the exercise parameters deviate from the risk value and exceed the risk threshold, it indicates that the deviation between the current patient's exercise status and the standard exercise template for the corresponding stage has exceeded the critical range of safe training and effective rehabilitation. An exercise adjustment strategy needs to be obtained first for subsequent steps.

[0112] Wearing difference rate is a percentage of the resistance difference value relative to the standard resistance range, used to characterize the degree of wearing abnormality.
[0113] Divide the resistance difference value by the standard resistance range (the difference between the maximum and minimum values), and then multiply by 100% to obtain the wearing difference rate.
[0114] S52: Determine whether the wearing difference rate exceeds the preset adjustment difference rate.
[0115] The adjustment difference rate refers to the maximum allowable wearing difference rate threshold for automatic adjustment; manual intervention is required when this threshold is exceeded.
