Summary

This completed study tested whether a low-cost prosthetic foot works as well as traditional ones for people with a below-knee amputation. Six participants performed balance, walking, and jumping tests with both types of feet. The goal was to see if the cheaper option could improve movement and satisfaction during everyday indoor and outdoor activities.

What this could mean

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

Active substance
Prosthetic foot (device)
What this could lead to
If the low-cost foot performs well, it could offer a more affordable option for amputees without sacrificing mobility or comfort.
What could go wrong
This is a very small study (6 people) that only compares two prosthetic feet. Results may not apply to all amputees, and the low-cost foot might not match the performance of higher-end prostheses.
