Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of rehabilitation training, and specifically to a rehabilitation training method for Parkinson's patients based on artificial intelligence. Background Art
[0002] Parkinson's disease is a neurodegenerative disease of the nervous system, mainly manifested as symptoms such as movement disorders, tremors, stiffness, and gait instability, seriously affecting the daily living ability of patients. Due to the progression of the patient's condition, Parkinson's patients need long-term support from family members or professional caregivers. How to improve the quality of life of Parkinson's patients and reduce the burden of home care has become an important topic in the combination of medicine, rehabilitation, and intelligent technology.
[0003] Most current Parkinson's rehabilitation trainings adopt standardized training methods without fully considering the differences in the individual motor abilities, cognitive states, and living environments of patients. The lack of personalized programs will lead to insignificant rehabilitation effects and the inability to make real-time adjustments according to the actual needs of patients. Existing technologies generally cannot provide accurate training content and dynamic adjustment mechanisms based on the comprehensive health status of patients.
[0004] Many existing rehabilitation training methods have a certain function of collecting motion data, but they are often lagging in real-time feedback and data processing, and cannot accurately adjust the training effect in a short time. The lack of support from adaptive algorithms makes the rehabilitation training unable to effectively respond in a timely manner according to the physiological and motion feedback of patients, resulting in limitations in the personalization and accuracy of the training effect.
[0005] Home rehabilitation is very important for Parkinson's patients, but existing technologies will ignore the safety assessment of the living environment, and the environmental factors of patients at home have not been given enough attention. Safety hazards in the environment, such as slips and obstacles, may cause accidents to patients, further affecting the rehabilitation effect. Existing technologies also lack intelligent environmental improvement suggestions and cannot effectively avoid safety risks.
[0006] Existing rehabilitation treatment technologies lack an effective remote medical management platform, and the health data of patients cannot be transmitted to doctors in real time for tracking and intervention. Especially Parkinson's patients usually require long-term rehabilitation training and monitoring. If doctors cannot obtain the rehabilitation data of patients in real time, they will not be able to make timely treatment adjustments, thus affecting the treatment effect. The limitations of existing technologies in remote medical support lead to blind spots in treatment management.
[0007] Current rehabilitation programs often focus on short-term rehabilitation effects and lack dynamic optimization for the long-term rehabilitation process. The rehabilitation effect fluctuates over time, and existing technologies fail to provide a comprehensive evaluation and adjustment mechanism based on long-term data. There is a lack of the ability to comprehensively evaluate multiple health indicators, which cannot ensure the continuous optimization of the rehabilitation program during the treatment cycle, resulting in stagnant rehabilitation effects for patients.
[0008] Many existing technologies lack prognosis prediction models and risk intervention mechanisms. The rehabilitation process of patients is affected by various factors, and existing technologies fail to conduct comprehensive evaluations through big data analysis and integrated learning methods. The lack of means to predict rehabilitation effects leads to patients being unable to obtain personalized intervention programs in a timely manner, increasing medical costs and risks.
[0009] Therefore, those skilled in the art provide a rehabilitation training method for Parkinson's patients based on artificial intelligence to solve the above-mentioned problems. Summary of the Invention

[0161] Step S6, based on the implementation results of the training plan adjusted in Step S4 and the evaluation results in Step S5, comprehensively calculate the patient's comprehensive health index, and transmit the evaluation results to the remote medical platform for medical staff to refer to;
[0162] Step 6.1, on the basis of the real-time health status index θ 1,t obtained in Step S2, the training preparation index θ 2,t obtained in Step S3, and the environmental improvement recommendation index θ 3,t generated in Step S5, a weighted average fusion method is used to comprehensively evaluate the long-term rehabilitation effect of the patient, and the long-term effect evaluation results are expressed using the formula as follows:

[0164] Step 6.2, based on the long-term effect evaluation value E calculated in step 6.1 t and the prediction error between the actually observed rehabilitation effect, adaptively update the reliability weights of each index through an online learning algorithm, and adopt the update formula:
[0165] π i (t + 1) = π i (t) + η[ε t ·θ i,t - λ·π i (t)],

[0167] Step 6.3, after completing steps 6.1 and 6.2, based on the latest comprehensive rehabilitation effect evaluation value E t use a non-linear mapping model to determine whether it is necessary to adjust the rehabilitation training plan, and adopt the decision function: D t = σ(ζ·(E t - τ)),
[0168] Among them, D t is the plan adjustment decision variable at time t, σ is the sigmoid function, E t is the comprehensive rehabilitation effect evaluation value at time t, τ is the preset rehabilitation effect target threshold, and ζ is the decision sensitivity coefficient;
[0169] Step S7, integrate the data and information obtained in the above steps through a standardized interface and adopt encryption measures to ensure the security of data transmission and storage;
[0170] Step 7.1: Based on the real-time health status indicators obtained in Step S2, the training preparation index generated in Step S3, the real-time feedback data collected in Step S4, the environmental improvement suggestion indicators extracted in Step S5, and the long-term rehabilitation effect value calculated in Step S6, fuse each data into a comprehensive feature vector z, and construct a prognosis prediction model using a prediction model based on ensemble learning. Use the formula:
[0171] to express the prognosis prediction output,
[0172] where, is the predicted future rehabilitation effect value, M is the number of base learners, and θ j is the weight coefficient of the j-th base learner, and g j (z) is the prediction output of the j-th base learner for the input feature vector z, and z is the comprehensive feature vector;
[0173] Step 7.2: Based on the prognosis prediction model constructed in Step 7.1, train and optimize the model parameter set Θ using the mean squared error loss function with a regularization term. Use the formula:
[0174] to express the model loss,
[0175] where, L(Θ) is the total loss value of the model parameter set Θ, N is the number of training samples, is the rehabilitation effect value obtained by the model prediction for the i-th sample, and Y i is the actually observed rehabilitation effect value for the i-th sample, Θ is the set of all trainable parameters of the model, and λ is the regularization coefficient;
[0176] Step 7.3: Based on the predicted rehabilitation effect obtained after training and optimization in Step 7.2, combine it with the preset rehabilitation effect target threshold Y th , and use a non-linear mapping decision model to generate a risk warning signal and a personalized intervention strategy adjustment suggestion. Use the formula:
[0177] to express the decision output,
[0178] where, W is the risk warning weight or intervention strategy adjustment signal, σ represents the sigmoid function, κ is the decision sensitivity coefficient, is the rehabilitation effect prediction value output by the prognosis prediction model, and Y th is the preset rehabilitation effect target threshold.
[0179] Step S1: Multi-sensor data collection and preprocessing. Use wearable sensors and environmental sensors to simultaneously obtain patient movement, heart rate, gait, and home environment data. After collection, the raw data is subjected to noise removal and filtering.
[0180] In step 1.1, the adaptive Kalman filtering algorithm is used. The system first makes a prediction and then updates the state estimate. The prediction formula, prediction error covariance, and Kalman gain are all calculated according to the set formulas.
[0181] Next, in step 1.2, the multi-scale wavelet decomposition and reconstruction algorithm is applied to the filtered signal. Threshold processing is performed on the detail coefficients of each layer and the signal is reconstructed to complete signal standardization and normalization. The algorithm makes full use of the local characteristics of wavelet decomposition to ensure fine data processing.
[0182] Step S2: Multi-sensor data fusion. The preprocessed multi-channel data are aligned and weighted fused to form a comprehensive index reflecting the overall health status of the patient.
[0183] In step 2.1, a calibration model is used to achieve data alignment. The signals of each sensor are multiplied by their respective calibration gains and the biases are subtracted.
[0184] Then, in step 2.2, the weights of each sensor are determined based on the exponential smoothing algorithm. The measurement uncertainties of each sensor affect the weight distribution to ensure the rationality of data fusion.
[0185] In step 2.3, the weighted linear fusion algorithm is used to add the calibrated data according to the preset weights to generate a comprehensive health status index. The comprehensive index can reflect the real-time status of the patient.
[0186] Step S3: Generate a personalized rehabilitation training plan. Based on the fusion index in step S2, data on the patient's movement, cognition, and home environment safety are extracted.
[0187] In step 3.1, each item of data is normalized and integrated into a training capacity factor using a weighted linear normalization model. Each index has its own weight, and the result is intuitive and easy for subsequent calculations.
[0188] In step 3.2, by combining the comprehensive health index and the training capacity factor, the patient's training readiness index is obtained through a multi-factor linear combination.
[0189] Furthermore, in step 3.3, specific training intensity parameters are generated through a non-linear mapping model. A regulation factor is used in the mapping process, taking into account the patient's existing physical fitness and also considering the rehabilitation needs to achieve the goal of personalized plan formulation.
[0190] Step S4: Real-time feedback and dynamic adjustment of the plan. During the training process, the system continuously collects the patient's movement and physiological feedback data.
[0191] First, in step 4.1, the real-time data are processed again through an adaptive Kalman filter to obtain an accurate state estimate.
[0192] Step 4.2 introduces a fuzzy logic control algorithm to dynamically adjust the training plan according to the current feedback error. The fuzzy control rules are not restricted to fixed formulas, but combine experience and real-time data to ensure that the training load always matches the patient's condition.
[0193] In step 4.3, a reinforcement learning algorithm is used to perform online learning on the plan. The new data continuously updates the training model, making the plan tend to be optimal.
[0194] Finally, in step 4.4, through the system evaluation algorithm, various training effect indicators are integrated to verify whether the adjusted training plan achieves the expected effect. The evaluation results provide a basis for subsequent adjustments.
[0195] Step S5: Home environment safety assessment and improvement suggestions, considering the safety of the patient during home training.
[0196] In step 5.1, the principal component analysis method is used to extract the features of the home environment data. After the data is standardized and dimension-reduced, the key features are retained.
[0197] Then in step 5.2, a logistic regression model is used to evaluate the environmental safety risk and give a risk score. The score is intuitive and quantifiable.
[0198] In step 5.3, through fuzzy inference, a defuzzification mapping is performed on the risk score to generate targeted environmental improvement suggestions. Here, it is no longer restricted to fixed rules, but is flexibly adjusted to ensure the practicality of the suggestions.
[0199] Step S6: Comprehensive rehabilitation effect evaluation and remote data transmission. During and after the training process, the system comprehensively evaluates the long-term rehabilitation effect of the patient.
[0200] In step 6.1, by combining real-time health indicators, training preparation index and environmental improvement suggestions, the weighted average method is used to calculate the rehabilitation effect evaluation value. The weight distribution fully considers the reliability of each indicator.
[0201] In step 6.2, the index weights are adaptively updated through an online learning algorithm to reduce the prediction error.
[0202] In step 6.3, it is determined whether further adjustment of the plan is needed according to the non-linear mapping decision model. This decision function is simple and direct, and can timely feedback potential risks.
[0203] The evaluation results are transmitted to the remote medical platform in real time, providing timely data support for doctors and realizing remote monitoring and intervention.
[0204] Step S7: Data integration and secure transmission. Finally, the data generated in each step is integrated through a standardized interface.
[0205] Step 7.1 Aggregate each data into a comprehensive feature vector as the input of the prognosis prediction model.
[0206] Step 7.2 Train the prediction model based on the mean square error loss function with a regularization term, and continuously optimize the model parameters.
[0207] Step 7.3 Use the non-linear mapping decision model to generate risk warning signals and suggestions for adjusting intervention strategies. Finally, the system ensures the security of all data transmission and storage through encryption measures to ensure that patients' privacy and data security are not threatened.
