FAST.AI recognizes facial asymmetry (drooping of facial muscles), arm weakness, and speech changes – all common stroke symptoms. This study is ongoing, and the mobile application is still in development and not available to the public.
The smartphone application uses video of the patient’s face to check 68 facial landmark points; sensors that measure hand movement and orientation; and voice recording to detect speech changes. Information from each test was sent to a database server for analysis.
The researchers conducted the FAST. AI𠏋 validated performance. Neurologists examining patients tested the app and then compared the FAST.AI results to their clinical impressions.
The analysis found that the smartphone app accurately detected facial asymmetry associated with stroke in nearly 100% of patients. The app accurately detected hand weakness in more than two-thirds of cases. Preliminary analyzes confirmed that it may be able to reliably detect sled speech.
Clot-busting medicine must be given within three hours of symptom onset. And the faster treatment is given, the better the chances for recovery: On average, 1.9 million brain cells die every minute a stroke goes untreated, according to the American Stroke Association, a division of the American Heart Association.
Previous research has found that people who are treated within 90 minutes of symptom onset are less likely to recover with little or no disability than those who are treated more than 90 minutes after symptom onset. approximately three times higher.
These preliminary results confirm that the app identifies acute stroke symptoms as accurately as a neurologist does, and they will help improve the app𠏋’s accuracy in detecting signs and symptoms of stroke.
A limitation of the study is that neurologists (individuals, not family members or caregivers) conducted the screening and taught patients how to use the app.
However, the app is a promising tool to address a major health challenge – how to motivate individuals with stroke symptoms to seek care in a short window of opportunity.Life Style
