      摘要 目的：探讨语义导航策略（SNS）对失语症患者命名能力的改善作用。 方法：14例失语症患者随机分为SNS组（n=7）和语义无关训练（US）组（n=7）。采用中文联想词汇中的122个词汇，SNS组按照网络分析技术自动生成的词汇顺序，US组则以随机词汇顺序呈现给患者。在西方成套失语症检查（WAB）和简易精神状态检查（MMSE）基线测试后，进行为期10d，每天1次言语训练，治疗前后应用75张训练图片评估患者的命名能力。 结果：SNS组治疗后正确反应数显著高于治疗前以及治疗后US组，治疗后无反应数也显著低于治疗前以及治疗后US组。SNS组治疗后的正确反应数与WAB命名得分呈显著正相关。 结论：SNS可以有效改善失语症患者的命名能力。

Abstract:

      Abstract Objective: To explore the effects of semantic navigation strategy (SNS) on naming ability in patients with aphasia. Method: Fourteen patients with aphasia were randomly divided into SNS group (n=7) and unrelated semantic (US) group (n=7). One hundred and twenty-two words chosen from Chinese word association norms were used in this study. The presentation sequence of words was generated automatically with network analysis techniques in SNS group and randomly without network analysis techniques in US group. After baseline tests of Western Aphasia Battery (WAB) and Mini Mental Status Examination (MMSE), all the patients with aphasia received speech training once a day for 10 consecutive days. The naming ability was evaluated with 75 pictures before and after training respectively in all the patients. Result: The number of correct responses after training in SNS group was significantly higher than that before training in the same group and that after training in US group. The number of no response after training in SNS group was significantly lower than that before training in the same group and that after training in US group. There was significantly positive correlation between the number of correct responses after training and the naming scores of WAB in SNS group. Conclusion: SNS may effectively improve the naming ability in patients with aphasia.
