Summary

This pilot study tested a new 3D-printed prosthetic foot designed to store and release energy, like a natural foot. Three people with below-knee amputation tried it during walking, stairs, and ramps. The goal was to see if it is safe and works as well as current carbon-fiber prosthetics.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
3D-printed prosthetic foot
What this could lead to
If successful, this could lead to more affordable, customized prosthetic feet that perform as well as current carbon-fiber models.
What could go wrong
This is a very small pilot study with only 3 participants, so results may not apply to everyone. The 3D-printed foot may break or cause discomfort.
