Chula’s Engineering Develops Dynamic Prosthetic Feet with International Standards and 5 Times Less the Cost

PRNewswire February 2, 2023

BANGKOK, Feb. 2, 2023 /PRNewswire/ — Thailand now has 39,647 people with disabilities, over 95% of whom are using poor-quality prosthetic feet which are heavy and do not have ankles. This can adversely affect the way they walk, as well as their lives.

The figures from the National Statistical Office of Thailand have inspired a research team from the Faculty of Engineering, Chulalongkorn University, to develop highquality dynamic prosthetic feet which are flexible and bendable and can store energy with each step. The prosthetic feet are made from carbon fibers, making them light weight but strong and durable. Users can walk in them on rough terrains, while exercising and during a light jog. The innovation has received the ISO 10328 strength standards from Germany and has been certified with the ISO 13485 for quality. It has also been registered as a medical device with the Food and Drug Administration (FDA), been granted a petty patent, and registered in Thai SME-GP. The prosthetic feet are currently in the process of being registered with Thai Innovation, requesting the Made in Thailand certificate, and requesting for the CE Marking.

Asst.┬áProf.┬áDr.┬áPairat Tangpornprasert from the┬áMechanical Engineering Department, Faculty of Engineering, Chulalongkorn University,┬áexplained that the dynamic prosthetic feet have undergone clinical trials with 20 patients with disabilities and yielded highly satisfactory results.┬áThe users require approximately 2 weeks to adjust to the prosthetic feet.┬áIn comparison with┬áthe imported prosthetic feet now available in the market, the innovation has comparable qualities and efficiency but with a 5 times cheaper cost of production.┬áThis can then help reduce the high cost of prosthesis and orthosis imports.┬áMoreover, commercial production of medical devices can expand the market overseas, leading to more generation of income, export opportunities, and the country’s competitiveness.

As an engineering lecturer with an interest in medical research, Asst. Prof. Dr. Pairat had to conduct interdisciplinary research and study, which is significant as working in a singular field may lead to difficulty in application of the research. 

“Developing dynamic prosthetic feet, which are considered a medical device, required the efforts of a network of doctors and prosthetists and orthotists sharing their expertise and interdisciplinary knowledge in order to achieve good-quality dynamic prosthetic feet that meet international standards.┬áI am proud to have successfully produced good-quality prosthetics and helped those with disabilities to regain function of their limbs,”┬áadded Asst.┬áProf.┬áDr.┬áPairat.┬á

The dynamic prosthetic foot project was funded by the National Research Council of Thailand.┬áIt is part of the prosthesis and orthosis for the disabled project under the┬á”New Beginnings with Research and Innovation”┬áto commemorate the Coronation of King Rama X.┬á67 dynamic prosthetic feet were given to people with disabilities at over 13 hospitals.┬áThe innovation is currently being considered for government medical benefit schemes so that it may be accessible for people with disabilities, which will help improve their quality of life.
