    This study introduces an algorithm to automatically detect standardized gait tests from continuous sensor data, eliminating the need for manual annotations. This advancement supports more efficient and automated gait analysis for diseases like Parkinson's disease.

    Area of Science:

    • Biomedical Engineering
    • Clinical Biomechanics

    Background:

    • Gait data analysis aids in diagnosing and managing diseases such as Parkinson's disease (PD).
    • While traditional clinical gait analysis uses standardized tests, long-term home-based analysis offers more realistic patient data but lacks context.
    • Instrumented gait tests require manual annotations for identification and processing, hindering efficiency.

    Purpose of the Study:

    • To develop an algorithm for automatic detection of standardized gait tests from continuous sensor data.
    • To make manual annotations of gait tests obsolete, thereby streamlining data processing.
    • To facilitate more efficient and automated gait analysis, potentially for home-monitoring systems.

    Main Methods:

    • The study employed an algorithm based on dynamic time warping (DTW).

  • DTW was used to compare input gait signals with predefined templates and quantify similarity.
  • Various templates were evaluated, and an optimized template was developed for classification.

    • Main Results:

    • The developed algorithm achieved a F1-measure of 86.7% in classifying gait tests.
    • Performance was evaluated on a dataset acquired in a clinical setting.
    • The method demonstrated effectiveness in automatically identifying standardized gait tests.

    Conclusions:

    • The developed algorithm successfully automates the detection of standardized gait tests, reducing reliance on manual annotations.
    • This approach holds promise for transfer to home-monitoring systems, enhancing remote patient assessment.
    • The findings contribute to more efficient and automated gait analysis for improved clinical insights.
