    Automated gait analysis provides objective data on walking patterns and therapeutic responses. This technology aids in assessing joint function and improving patient outcomes through detailed gait reports.

    Area of Science:

    • Biomechanics
    • Rehabilitation Engineering
    • Clinical Measurement

    Background:

    • Objective quantification of gait is crucial for understanding functional deficits and treatment efficacy.
    • Traditional gait assessment methods can be subjective and lack detailed quantitative data.
    • Advancements in technology enable more precise and comprehensive gait analysis.

    Purpose of the Study:

    • To describe the instrumentation and methodology for automated gait analysis.
    • To highlight the applications of automated gait analysis in clinical practice.
    • To demonstrate the reliability and utility of this technology for patient assessment.

    Main Methods:

    • Utilized three-dimensional electrogoniometers for joint rotation measurement (hip, knee, ankle).
