    Area of Science:

    • Biomedical Engineering
    • Prosthetics and Orthotics
    • Rehabilitation Medicine

    Background:

    • Hand amputations and congenital absences significantly impact patient quality of life.
    • Existing prostheses often have limitations in function and cosmetic appearance.
    • Innovative solutions are needed to improve outcomes for individuals with hand differences.

    Purpose of the Study:

    • To describe a novel hand prosthesis design.
    • To introduce a wrist-actuated grip mechanism for hand prostheses.
    • To evaluate the functional and cosmetic outcomes of the new prosthesis.

    Main Methods:

    • Development of a prosthesis utilizing wrist flexion/extension for grip control.
    • Creation of a lifelike, flexible glove covering using a silicone polymer.
