Key Takeaways

An AI-guided bionic hand can provide amputees greater dexterity

The AI is pre-programmed to guide the hand into different postures, using pressure and proximity sensors

Amputees then drive the AI, allowing them to more deftly control the bionic hand

FRIDAY, Dec. 12, 2025 (HealthDay News) — The best way to improve amputees’ control over a bionic hand is to give the hand a mind of its own, a new study argues.

A bionic hand that’s controlled by an artificial intelligence (AI) program, but under the direction of the amputee, provides the best approximation of normal hand dexterity, researchers said Dec. 9 in the journal Nature Communications .

“As lifelike as bionic arms are becoming, controlling them is still not easy or intuitive,” said lead investigator Marshall Tro
