    Area of Science:

    • Biomechanics
    • Prosthetics and Orthotics
    • Rehabilitation Engineering

    Background:

    • Optimizing prosthetic limb fit and alignment is crucial for amputee mobility and comfort.
    • Current methods may not fully address the dynamic nature of gait and prosthetic interaction.

    Purpose of the Study:

    • To develop and present systematic methods for optimizing the fitting and alignment of artificial legs.
    • To enhance prosthetic function through detailed analysis of gait and component interaction.

    Main Methods:

    • Gait analysis was employed as the foundation for developing optimization procedures.
    • Key aspects investigated include stump-prosthesis interface (socket) geometry, prosthetic component selection, and dynamic alignment.
    • Amputee adaptation to imposed prosthetic perturbations was studied.

    Main Results:

    • Systematic procedures for artificial leg fitting and alignment were established.
    • The study identified critical factors in socket geometry and component selection for optimal performance.
    • Dynamic alignment strategies were refined based on gait analysis.

    Conclusions:

    • The developed methods provide a systematic approach to improving artificial leg functionality.
    • Understanding amputee adaptation and compensatory mechanisms is vital for prosthetic design and alignment.
    • Optimized prosthetic fitting and alignment can significantly enhance amputee mobility and quality of life.
