AI-Guided Ultrasound Needling of Xinwu Point for Allergic Rhinitis

A Study of Artificial Intelligence-Assisted Visualization-Guided Acupuncture at the "Xinwu Point" for Allergic Rhinitis

This study evaluated a new way to perform acupuncture at a deep point called the Xinwu point (sphenopalatine ganglion) for allergic rhinitis (hay fever-like nasal allergy). The point is hard to reach with the usual blind needling method. Artificial intelligence (AI) with real-time ultrasound images was used to help the acupuncturist see nearby structures and guide the needle. Sixty adults were randomly assigned to AI-guided needling or usual blind needling. Both groups received the same acupuncture schedule: both sides of the face, once a week, for six sessions. The primary aim was to measure how accurately the needle reached the target. Side effects, nasal symptom scores, overall improvement, and how acceptable participants found the procedure were also recorded.
