MIT designs better fit for the Jaipur Foot

A team of students at MIT,  including an Indian, has come up with an improved and better  fitting design for the Jaipur Foot, an artificial leg for amputees.

The new method uses a hand-powered system to build the prosthetic that is expected to last longer than the ones currently being built and sold in the country by the Rajasthan-based charity, Jaipur Foot Organisation, according to news from MIT.

The modified design that eschews dependence on electricity is also expected to bring down the cost of the artificial limbs and benefit more patients in rural areas. The present electrically powered fitting system often requires bringing along a bulky generator.

The JFO, also known as the Bhagwan Mahavir Viklang Sahyata Samiti, claimed to be the world's largest provider of prosthetics, currently manufactures artificial legs using electric power to create the mould with Plaster of Paris.

The new design of the custom-built limbs is the result of a year-long

project by the Mechanical Engineering wing of the MIT, the four participants of which spent two weeks in Jaipur in January this year and conducted one test run of a fitting.

"The personnel at the JFO were really pleased with the results," says engineering student Maria Luckyanova, who was in the country for testing the device.

"They liked the fact that the new system produced less waste, required no electricity and seemed to produce a better fit that might lead to a longer-lasting prosthetic. That's because the plaster of paris in the traditional method shrinks slightly as it hardens, making the fit less exact," says Luckyanova.
