Electroacupuncture-Induced Changes in Tongue Features in Early Stroke Patients Using ZMT-1A Imaging System

Electroacupuncture is applied using standardized stroke rehabilitation protocols. Needles are inserted at acupoints including LI15 (Jianyu), LI11 (Quchi), TE5 (Waiguan), LI4 (Hegu), GB30 (Huantiao), ST36 (Zusanli), and GB34 (Yanglingquan), and connected to an electroacupuncture device delivering alternating current stimulation at 10-20 Hz. Each session lasts 15-20 minutes, performed once daily, 5 days per week, for 4 weeks. The intervention follows Vietnam's national traditional medicine guidelines for post-stroke recovery.
