Question: Does remote ischemic conditioning improve neurological function in patients with acute moderate ischemic stroke? Findings: In this randomized clinical trial that included 1893 participants with acute moderate ischemic stroke, excellent neurological function at 90 days in those randomized to remote ischemic conditioning compared with usual care occurred in 67.4% vs 62.0%, a difference that was statistically significant.Meaning: Although remote ischemic conditioning was associated with better neurological function in patients with acute moderate ischemic stroke, this trial requires replication before concluding efficacy for this intervention.
