Effect of Scalp-acupuncture Treatment on Language Reorganization in Poststroke Aphasia：A Functional Near-Infrared Spectroscopy

Objective Based on functional near infrared spectroscopy （fNIRS），to explore the scalp targeting language function and its neurological mechanism of action in patients with post-stroke aphasia （PSA）. Methods A total of 64 PSA patients hospitalized in the Rehabilitation Hospital Affiliated to Fujian University of Traditional Chinese Medicine from July 2022 to September 2023 were selected，and a table of random numbers was generated using SAS 9. 1 statistical software，and each group was divided into a control group and an observation group according to a 1：1 ratio，with 32 cases in each group. The control group received conventional speech rehabilitation therapy （speech training，language imitation，figure-word matching，numerical reading/writing/calculating and social communication skills training，etc. ），medication and health education; the observation group received scalp acupuncture on the basis of the control group，selecting the language function area （2/5 below the parietal anterior temporal diagonal line and the anterior temporal line），and then stabbing it either flatly or obliquely，and then retained for 30 minutes post-needling sensation （deqi），and the speech and language treatment was carried out by the speech rehabilitation therapist in the process. Both groups were treated for 30 min/session，once/day，5 times/week for 4 weeks. Before and after the treatment，the patients were evaluated by the Beijing Medical University Aphasia Battery of Chinese （ABC）; the patients were evaluated by the Chinese Functional Communication Profile （CFCP）; the subjects were tested for changes in cortical hemoglobin oxyhemoglobin （HbO2） and hemoglobin deoxyhemoglobin （HbR） by using the fNIRS; and the patients were evaluated by using the verbal fluency task by using the E-prime 3. 0 software. The correlation between the activation of brain regions during the verbal fluency task and the verbal fluency scores of the observation group was analyzed. Results （1）ABC，CFCP and verbal fluency scores：Compared with the pre-treatment period，the ABC，CFCP and verbal fluency scores of the two groups increased significantly after treatment，and the difference was statistically significant （P0. 05），and the verbal fluency scores were significantly higher after treatment （P
