New Tripod Prosthetic Foot for Amputees

Researchers at Stanford University introduce a new prosthesis foot similar to a tripod. This new prosthesis comes with sensors to monitor movement and milieu. Further, this device offers stability while walking on bumpy terrains, too.

Tripod Prosthesis a Boon to Users

According to statistics, nearly 500,000 people in the U.S. are amputees. Such people are at high risk of falls. Further, currently available prosthesis in the market do not offer the stability to use them safely in rough terrains. This affects the quality of life decreasing mobility and social life engagements. However, the good news is this can be now taken care by the new prosthesis.

New prosthesis comes with two forward facing toes and one a rear facing heel. This minimizes the risk of fall in the rough terrain regions by offering safety to the users. This device provides a balance by shifting the pressure at three contact points, which are two toes and one rear heel. This, in turn provides more stability on rough and uneven pathways. The sensors in the device monitor the movement on uneven terrains. These sensors work similar to someone flexing their ankles to balance their feet on the rough and uneven ground.

Chiu, a researcher says the major constraint in making of tripod prosthesis is achieving a lightweight and cost effectiveness of this device. Lengthy manufacturing process plays a hurdle in achieving this state. It can take several years to hit the market in real time scenario. Another researcher, Steven Collins says we can apply any design on this prototype without investing on new hardware every time. The research team can tweak this design without stressing over its real time use.
