NEW DELHI: Indian Institute of Technology, Guwahati (IITG) developed an affordable prosthetic leg with advanced features particularly suitable for the Indian population.
Researchers at the institute collaborated with 151 Army Base Hospital for the usage. Keeping in mind the rigid terrain and ability to move legs in normal positions, researchers developed this prosthetic leg for different age groups with multiple stages of prosthesis use.
Prof S Kanagaraj, Department of Mechanical Engineering, IIT Guwahati, said, “Knee joint developed by our team has a spring-assisted deep squat mechanism, which helps to use the Indian toilet system more comfortably.”
“The knee rotating mechanism helps to have cross-legged sitting; the locking mechanism helps to reduce the fear of falling of patients while walking in unknown terrain; adjustable link length in a knee helps to have either more stability or easy flexing depending on age and requirement of the patients. Overall, the knee joint is designed to meet the Indian lifestyle which other products fail to fulfil,” Prof Kanagaraj, who led the research team, added.
Amputees were able to use the different functionalities of the prosthetic leg with and without any additional support in their daily life.
A methodology is being developed to fit a 3D-printed test socket which is verified using computer analysis.
