The Stroke Recovery Initiative at UCSF is designed to help people who have had a stroke to connect with researchers who are applying the latest science and technology to develop new treatments for stroke recovery. Anyone who is 18 years of age or older and has had a stroke may submit a survey to join. The self-reported information on the survey will be used to match participants to current or future stroke research studies and study personnel for each specific study may contact participants for further screening. Some studies are recruiting participants nationally, not just in the San Francisco Bay Area.
