Development of the HINTS/HINTS+ Exam Smartphone App and AI Integration
This project examined the effectiveness of the new technology HINTS/HINTS+ (Head-Impulse, Nystagmus, Test of Skew, plus hearing) exam in detecting posterior circulation strokes, which often present atypically and delay treatment. We developed an iOS application to support the HINTS/HINTS+ exam and improve stroke detection. Ten patients with vestibular symptoms were assessed using the application, with 1 correctly identified central and 9 peripheral pathologies. The application showed 100% sensitivity and 66.7% specificity. It allowed video replay for examiners to assess nystagmus and head impulse saccades better than clinical nonvideo testing. Results suggest wider HINTS application use, with future improvements through artificial intelligence.
