Stroke rehab using AI and a smartphone app
This trial tests a smartphone-based therapy (RGS) that uses AI to help people who had a stroke more than 6 months ago improve arm and hand movement. It's for those with mild to moderate arm weakness who can use a phone and sit during therapy sessions.
LimogesAges 18 years+ - NCT07138768Recruiting
Using MRI to diagnose acute stroke faster in the ER
This trial tests how using MRI can help doctors diagnose acute stroke faster in the emergency room. It may lead to quicker treatment and better outcomes for stroke patients.
