Summary
This study developed an affordable, body-powered lower limb prosthesis for transfemoral amputees in developing countries. The mechanical prosthetic device successfully restored the wearer's ability to walk functionally.
Area of Science:
- Biomedical Engineering
- Rehabilitation Engineering
- Prosthetics and Orthotics
Background:
- High-tech prostheses are often unaffordable in developing countries, limiting mobility for amputees.
- There is a need for cost-effective, functional lower limb prosthetic solutions.
Purpose of the Study:
- To design and fabricate a mechanical, body-powered transfemoral prosthetic device.
- To restore functional ambulation for transfemoral amputees using an accessible design.
Main Methods:
- Utilized anthropometric measurements for user-friendly, ergonomic design via AutoCAD.
- Employed engineering methods including casting and welding for fabrication.
- Materials included polypropylene, galvanized iron, and perlite.
Main Results:
- A functional transfemoral prosthesis was successfully fabricated.
- The prosthetic limb incorporated a polypropylene socket, a galvanized iron knee joint with suspension, and a perlite foot.
- Evaluation confirmed restoration of ambulatory function.
Conclusions:
- The developed body-powered transfemoral prosthesis offers a viable, affordable solution for amputees.
- This design can significantly improve mobility and quality of life in resource-limited settings.
