Robot suit gets ICU patients on their feet faster after chest surgery
NCT ID NCT07220733
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a self-balancing exoskeleton called Atalante X can safely help patients stand and walk soon after chest surgery in the ICU. Being immobile after surgery can lead to muscle weakness and other complications, but early movement may improve recovery. The trial will enroll 5 adults and track safety, ease of use, and any improvement in mobility.
