Abstract
Description
Technical Field
[0001] This invention relates to the field of medical rehabilitation information technology, specifically to an intelligent assessment system for rheumatoid arthritis rehabilitation based on the ICF concept and classification system. Background Technology
[0002] The International Classification of Functioning, Disability and Health (ICF) is a classification system published by the World Health Organization. It provides a standardized language and framework for describing health status outcomes, comprehensively assessing an individual's health status from three dimensions: physical function and structure, activity, and participation, rather than just focusing on the disease itself. Applying the ICF framework in the rehabilitation assessment of rheumatic diseases can more comprehensively and accurately reflect the degree of functional impairment, the impact on daily living activities, and the problems faced by patients in social participation.
[0003] Patent publication number CN119274800A describes in its specification that "This invention relates to the field of medical rehabilitation technology, specifically to a remote intelligent rehabilitation assessment system. The system includes a rehabilitation monitoring module, a remote service module, an interactive feedback module, and an intelligent assessment module; the rehabilitation monitoring module includes an emotional signal monitoring module, a physiological signal monitoring module, and a gamified performance monitoring module, used to monitor the patient's emotional state, physiological state, and reaction status; the remote service module connects the rehabilitation monitoring module, the interactive feedback module, and the intelligent assessment module; the interactive feedback module is used for information exchange and feedback between the patient, rehabilitation therapist, and the remote service module; the intelligent assessment module is used to evaluate the remote service..." The rehabilitation index data and optimized rehabilitation information obtained from the module are analyzed and evaluated. This invention achieves remote, comprehensive, and refined intelligent assessment of patient rehabilitation by comprehensively monitoring the patient's emotional, physiological, and reactive states. While the aforementioned technology, based on multi-source data fusion and dynamic weight allocation, achieves precise and personalized intelligent rehabilitation management through collaborative assessment of emotional, physiological, and reactive dimensions, combined with gamified testing and adaptive algorithms, traditional assessment systems struggle to balance the dynamic coupling of patients' multidimensional health states and group heterogeneity. In the assessment and decision-making process, the single assessment dimension, static and isolated data, and difficulty in adapting to individual differences lead to crude intervention strategies and low effectiveness.
[0004] In conclusion, the development of an intelligent assessment system for rheumatic disease rehabilitation based on the ICF concept and classification system remains a key issue that urgently needs to be addressed in the field of medical rehabilitation information technology. Summary of the Invention

[0009] The data feature module, based on the latent profile analysis algorithm, performs high-dimensional feature dimensionality reduction processing based on the evaluation results and radar chart to identify the hidden subtype;
[0010] The causal intervention module, based on the aforementioned hidden subtype, utilizes structural equation modeling to construct a causal path network and combines it with knowledge graph technology to generate a targeted intervention strategy library.
[0011] The closed-loop feedback module is used to establish a two-way feedback mechanism between evaluation and decision-making, and to input the feedback into the dynamic evaluation module to optimize the weight allocation and iteratively update the causal path network.
[0012] Beneficial effects

This helps to solve the problems of traditional assessment having a single dimension, static and isolated data, and difficulty in adapting to individual differences, and is conducive to improving the accuracy of intervention strategies and the rehabilitation effect of patients.

[0023] Example:
[0024] like Figure 1 As shown, this invention provides an intelligent assessment system for rheumatic disease rehabilitation based on the ICF concept and classification system, including:
[0025] A multi-source data module is used to collect and integrate multi-dimensional data;
[0026] Furthermore, the operation process of the multi-source data module includes:
[0027] The system is used to collect and integrate multi-dimensional data. Through an API interface protocol, it connects with hospital information systems, image archiving, and communication systems to collect patients' biochemical test data, imaging data, and medication records in real time. Simultaneously, a patient-side interactive interface is developed to support self-assessment data entry based on the five dimensions of the ICF framework: disease activity, physical function, quality of life, social support, and work efficiency. The patient-side app interface supports the completion of the ICF five-dimensional questionnaire, generating the following self-assessment data vector:
[0028]
[0029] In the formula, This represents a five-dimensional evaluation vector within the ICF framework. This represents a set with five elements. Represents any number of Evaluation scores in each dimension, The score range for each dimension is from 0 to 1, where 0 represents very poor and 1 represents excellent. All scales are standardized and mapped to the [0,1] interval. A data fusion algorithm is constructed using DS evidence theory. For data conflict scenarios, a manual review process is initiated through outlier cross-validation rules. Trust assignments are provided from both data sources, and the synthesized evidence is as follows:

[0034] Specifically, the multi-source data module of this system collects patients' biochemical test data, medical imaging data, and medication records in real time through API interfaces with medical information platforms such as hospital information systems, image archiving, and communication systems, ensuring the comprehensiveness and timeliness of clinical data. At the same time, a patient-side app was developed, and a self-assessment questionnaire with five dimensions (disease activity, physical function, quality of life, social support, and work efficiency) was designed based on the ICF theoretical framework. Patients can directly enter their subjective feelings, generating standardized five-dimensional assessment vectors. The scale scores are uniformly mapped to the 0 to 1 interval, facilitating unified analysis and enhancing the completeness and multi-dimensional understanding of information. Based on the standardized patient self-assessment scale, subjective and objective data are effectively combined. The introduction of evidence theory improves the reliability and robustness of data fusion. Combined with a manual review mechanism, it facilitates the timely identification and processing of abnormal data.
[0035] The dynamic evaluation module, based on ICF theory, constructs a dynamic weight allocation model and updates the evaluation results and radar chart according to the multi-dimensional data.
[0036] Furthermore, the operational process of the dynamic evaluation module includes:

In the formula, Indicates time Historical assessment data set, Indicates time The system uses historical assessment data sets and visualizes assessment trends to update assessment results and radar charts.
[0046] Specifically, this system, targeting neurorehabilitation patients, continuously monitors five dimensions: physical function, activity level, participation, environmental factors, and psychological state. It dynamically adjusts the weights of each indicator to accurately reflect subtle changes in the patient's rehabilitation process. Bayesian networks reveal causal paths between different dimensions, helping to identify key influencing factors and enabling targeted rehabilitation interventions. The dynamic weight allocation mechanism improves the sensitivity and adaptability of the assessment, while Bayesian network causal modeling enhances the scientific rigor and reliability of the assessment.

For rheumatic disease rehabilitation management, it processes multidimensional data including disease indicators, quality of life scores, and functional assessments to finely segment patients and identify different pathological subtypes, such as inflammation-dominant and functional impairment types. This provides a scientific basis for subsequent personalized treatment and intervention, achieving effective dimensionality reduction and reasonable grouping of high-dimensional data.

Identifying hidden subtypes helps reveal the heterogeneity of patient groups, supports the development of personalized medical plans, and improves clinical diagnosis and treatment outcomes and patient management levels.
