Arm cuff may boost brain recovery after stroke: major trial underway
NCT ID NCT06931535
First seen Jun 27, 2026 · Last updated Sep 18, 2026 · Updated 2 times
Summary
This study tests whether a simple, non-invasive treatment called remote ischemic conditioning (RIC) can help people recover better after a moderate stroke in the back part of the brain. RIC involves briefly inflating a blood pressure cuff on the arm to restrict blood flow, then releasing it, which may protect the brain. The trial will enroll 960 adults who had a stroke within the last 48 hours and have moderate symptoms. The goal is to see if RIC improves the chance of a good recovery (being able to live independently) 90 days later.
