Methods 60 patients were randomly divided into a treatment group treated by acupuncture associated with language training and a control group treated by simple language training. Tongue-acupuncture was applied as the main therapy, and language training included speech organ training, mouth-shape and voice training, spoken language expression training and practical communication ability training. According to Aphosio Bottery of Chinese （ABC）, language ex- amination evaluation was made, and event related potential （P300） was detected before and after treatment. Results The therapeutic effect in the treatment group was significantly better than that in the control group （P〈O. 05）, and the scores of ABC items including information content, speech fluency, repetition, vocabula- ry denomination, color naming, response denomination, confirmation or negation, acoustic recognition and carrying out instruction in the treatment group were obviously higher than those in the control group （P〈0.05）. After one course of treatment, the latencies of N2 and P3 waves in P300 were significantly short- ened and the amplitude of P3 was significantly elevated in the treatment group, compared with those in the control group （P〈0.05）. Conclusion Acupuncture combined with language training provided remarkable therapeutic effects in treating cerebral infarction-induced motor aphasia, and it was better than simple lan- guage training. The results of enhancing of the ABC scores including information content, speech fluency, repetition, vocabulary denomination, color naming, response denomination, confirmation or negation, acous- tic recognition and carrying out instruction, and shortening of the latencies of N2 and P3 waves in P300 and ele- vation of P3 amplitude may be taken as the indices for evaluating and anticipating clinical therapeutic effects of the therapy for treating the disease, which may also be some of the mechanisms.展开更多
