    Area of Science:

    • Neuroscience
    • Rehabilitation Medicine
    • Biomedical Engineering

    Background:

    • Stroke significantly impacts motor function, necessitating reliable assessment tools.
    • Current automatic evaluation methods often overlook raw kinematic data.
    • Accurate prediction of motor impairment is crucial for effective rehabilitation.

    Purpose of the Study:

    • To investigate the predictive power of raw kinematic trajectories for stroke impairment.
    • To compare different machine learning models for predicting Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) scores.
    • To explore the potential of trajectory data in telerehabilitation.

    Main Methods:

    • Collected kinematic data of the trunk and upper limb from 21 chronic stroke patients during reaching tasks.
    • Utilized machine learning models, including transformer-based networks, Residual Neural Network (ResNet), and support vector regression (SVR).
    • Integrated trajectory data to predict FMA-UE scores.

    Main Results:

    • A transformer-based model demonstrated superior performance in predicting FMA-UE scores.
    • The forward reaching task yielded the highest prediction accuracy (R²=0.905±0.028).
    • Predicted FMA-UE scores showed strong correlation with actual patient assessments.

    Conclusions:

    • Raw kinematic trajectory data can effectively predict motor impairment levels after stroke.
    • Transformer models show significant potential for automated stroke assessment.
    • This method offers a viable approach for remote monitoring and telerehabilitation.
