    Background:

    • Quantifying human gait with sensors offers significant potential for health and rehabilitation.
    • Objective gait measurements in daily environments can reveal disease impact and intervention responses.
    • Existing gait event detection methods struggle with irregular gait patterns.

    Purpose of the Study:

    • To develop a novel unsupervised method for detecting gait events and duration.
    • To improve the accuracy of gait analysis, especially for irregular gait patterns.
    • To enhance the objective measurement of gait in real-world settings.

    Main Methods:

    • Proposed a two-step unsupervised approach combining gait event candidate exploration with biomechanical restriction-based selection.

  • Utilized data from single-axis gyroscopes placed on both ankles.
  • Evaluated the method across three experimental conditions and a longitudinal free-living dataset.

    • Main Results:

    • The novel method significantly decreased timing errors in detecting gait events (toe off, heel strike) for irregular gaits compared to conventional methods.
    • Improved accuracy in measuring gait duration within a longitudinal free-living dataset.
    • Successfully distinguished between gait and non-gait actions.

    Conclusions:

    • The proposed unsupervised method offers a more robust and accurate approach to human gait quantification.
    • This technique has strong potential for improving remote patient monitoring and rehabilitation.
    • Enhanced gait analysis can provide deeper insights into daily living activities and disease progression.
