    Area of Science:

    • Biomedical Engineering
    • Rehabilitation Medicine
    • Machine Learning

    Background:

    • Manual rehabilitation level evaluation is subjective and inefficient.
    • Automatic systems require accurate assessment of patient progress.
    • Surface electromyography (sEMG) signals offer objective physiological data.

    Purpose of the Study:

    • To develop an automated method for evaluating stroke patients' rehabilitation levels.
    • To improve the efficiency and objectivity of rehabilitation assessment.
    • To leverage multi-channel sEMG signals for accurate classification.

    Main Methods:

    • Investigated correlation between rehabilitation levels and training actions.
    • Selected optimal actions for rehabilitation assessment.
    • Extracted features from selected sEMG signals.
    • Trained a stacking ensemble classification model.

    Main Results:

    • Achieved 94.36% classification accuracy for 6 Brunnstrom stages.
    • Demonstrated the validity and feasibility of the sEMG-based approach.
    • Identified key features from sEMG signals for rehabilitation assessment.

    Conclusions:

    • The proposed ensemble learning method effectively automates stroke rehabilitation level evaluation.
    • This approach enhances accuracy compared to traditional subjective methods.
    • Facilitates the practical application of home-based rehabilitation training.
