Semantic Navigation Strategy Improved Naming Ability In Patients With Aphasia／sun Li,jiang Zhongli,lin Feng, Et Al

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 language training once a day for ten consecutive days. The naming ability was evaluated with 75 pictures before and after training respectively in all the patients.Results:The number of correct response 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 a significantly positive correlation between the number of correct response after training and the naming score of WAB in SNS group. Conclusion:Semantic navigation strategy may effectively improve the naming ability in patients with aphasia. Objective:To explore generalization effect of semantic navigation strategy (SNS) on vocabulary naming 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 language training once a day for ten consecutive days. Recording the number of correct response everyday in order to draw the learning curve. The generalization effect was evaluated with 46 untrained items before and after training respectively in all the patients.Results:The learning curve of SNS group was steeper than that of US group. The number of correct response of trained items in SNS group was significantly higher than that in US group after the sixth day of training. The number of correct response of untrained items 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 of untrained items after training in SNS group was a decline tendency in comparison with that before training in the same group and that after training in US group.Conclusion:Semantic navigation strategy may promote significant generalization effect while improving the learning curve in vocabulary naming of patients with aphasia.
