    Area of Science:

    • Biomedical Engineering
    • Computer Science
    • Neurology

    Background:

    • Abnormal gait recognition is crucial for diagnosing and monitoring neurological and musculoskeletal disorders.
    • Existing methods may lack the precision required for nuanced gait analysis.

    Purpose of the Study:

    • To develop and validate MSCAF-Gait, a Multi-Scale Cross-Attention Fusion Network for abnormal gait recognition using foot pressure sensors.
    • To introduce the Pressure-Insole Abnormal Gait (PIAG) dataset for research on gait abnormalities.

    Main Methods:

    • Utilized multi-scale convolutional modules with channel and spatial attention mechanisms.
    • Incorporated a novel cross-attention fusion module for enhanced feature representation.
    • Developed and utilized the PIAG dataset, alongside the GaitinPD dataset, for model evaluation.

    Main Results:

    • Achieved 99.61% accuracy in Parkinsonian gait recognition and 98.88% accuracy in Parkinson's severity classification on the GaitinPD dataset.
    • Attained 99.42% accuracy on the PIAG dataset, which includes diverse abnormal gait patterns.
    • Demonstrated a lightweight architecture with reduced computational load (FLOPs and parameters).

    Conclusions:

    • MSCAF-Gait effectively recognizes abnormal gait patterns with high accuracy.
    • The model's computational efficiency makes it suitable for real-time applications on wearable devices.
    • The PIAG dataset provides a valuable resource for advancing abnormal gait recognition research.
