Summary
This study developed an intelligent grading model for upper limb motor control using robot-assisted rehabilitation data. The model accurately assesses functional impairments, improving rehabilitation efficiency and objectivity.
Area of Science:
- Rehabilitation Engineering
- Biomedical Data Science
- Clinical Assessment
Background:
- Rehabilitation assessment is crucial for effective treatment.
- Traditional methods can be subjective and time-consuming.
- Objective, quantitative assessments are needed for personalized interventions.
Purpose of the Study:
- To quantitatively assess upper limb motor control ability.
- To develop an intelligent grading model for functional impairments.
- To enhance the efficiency and objectivity of clinical rehabilitation assessment.
Main Methods:
- Collected upper limb movement data from patients using a rehabilitation robot.
- Extracted 22 metrics related to movement efficiency, smoothness, and accuracy.
- Applied data augmentation (SMOTE) and an Extreme Gradient Boosting Tree (XGBoost) model for grading.
Main Results:
- Screened and normalized 16 key assessment metrics.
- Developed a weighted fusion approach for quantitative motor control scores.
- Achieved >0.98 accuracy with the XGBoost model on the enhanced dataset, improving precision, recall, and F1-score.
Conclusions:
- The study provides a quantitative method for assessing motor control and grading functional impairments.
- The intelligent grading model significantly improves rehabilitation assessment efficiency.
- This approach overcomes limitations of traditional subjective and lengthy assessment methods.
