    Area of Science:

    • Prosthetics and Orthotics
    • Rehabilitation Engineering
    • Biomedical Engineering

    Background:

    • Standard full-length prostheses pose challenges for bilateral amputees in activities like fast walking and stair negotiation.
    • Short prostheses (stubbies) with non-articulated rocker bottoms are often used, particularly for geriatric amputees.
    • Existing prosthetic solutions may limit functional independence for individuals with bilateral lower limb loss.

    Purpose of the Study:

    • To develop and evaluate an interchangeable prosthetic system for bilateral above-knee amputees.
    • To enhance functional mobility and independence for amputees, particularly in developing countries.
    • To provide a versatile prosthetic solution that can be adapted for different functional needs.

    Main Methods:

    Related Experiment Videos

  • An interchangeable system was designed to convert a standard above-knee prosthesis into a stubby prosthesis.
  • The conversion involves replacing the shin and foot piece with an articulated hollow rocker attached to the socket/knee unit.
  • The system allows for tilting of the socket/knee unit via the articulated rocker junction.

    • Main Results:

    • The interchangeable system allows a single prosthesis to function as both a full-length and a stubby device.
    • The articulated rocker enables tilting of the socket/knee unit, facilitating lower body positioning for tasks like using Indian toilets.
    • The design aids amputees in performing outdoor activities such as gardening and fieldwork.
    • The system is particularly beneficial for bilateral amputees in resource-limited settings.

    Conclusions:

    • The developed interchangeable prosthesis system offers a versatile and practical solution for bilateral amputees.
    • This innovation enhances functional capabilities, promoting greater independence in daily living and occupational activities.
    • The system holds significant potential for improving prosthetic care and accessibility for amputees in developing nations.
