    Area of Science:

    • Biomedical Engineering
    • Prosthetics and Orthotics
    • Digital Imaging

    Background:

    • Traditional methods for measuring residual limb shapes can be time-consuming and subjective.
    • Accurate shape capture is crucial for effective prosthetic limb fitting and fabrication.
    • Student prosthetists require effective tools to learn and practice shape modification techniques.

    Purpose of the Study:

    • To introduce an automated method for measuring the 3D shape of plaster replicas of residual limbs.
    • To evaluate the utility of a computer-based instrument as a teaching aid for student prosthetists.
    • To assess the ability of the system to visualize and analyze shape modifications made by trainees.

    Main Methods:

    • Development of an automatic instrument for digitizing the full 3D shape of plaster replicas.
    • Utilizing computer software to store and process the digitized shape data.
    • Superimposing computer-generated cross-sections of unmodified and modified replicas to highlight changes.

    Main Results:

    • The developed instrument successfully digitizes and stores the complete 3D geometry of residual limb replicas.
    • The computer visualization allows for clear examination of shape modifications introduced by student prosthetists.
    • The system provides a quantifiable method to assess the accuracy and effectiveness of trainee adjustments.

    Conclusions:

    • The automated 3D shape measurement instrument serves as a valuable teaching aid in prosthetics education.
    • This technology enhances the learning process by providing objective feedback on shape modification skills.
    • The system facilitates a deeper understanding of the relationship between modification techniques and final shape outcomes.
