Observation On Therapeutic Effects Of Semantic Navigation Training Implemented By Laypersons On Improvement Of Speech Function In Patients With Aphasia

Objective:To explore the effects of semantic navigation training (SNT) applied by laypersons on improvement of speech function in patients with aphasia.Method:Twenty patients with aphasia were randomly divided into SNT group (n=10) and unrelated semantic (US) group (n=10). 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 SNT group and randomly without network analysis techniques in US group. All the patients with aphasia received speech therapy implemented by laypersons once a day for 10 consecutive days. Speech function was evaluated with Western Aphasia Battery (WAB) and Mini-communicative activity log (Mini-cal) before and after therapy respectively in all the patients.Results:The fluency, comprehension and aphasia quotient of WAB after therapy were significantly higher in SNT group than in US group. All the subitems and aphasia quotient of WAB in SNT group were significantly higher after therapy than before therapy. All the subitems and total score of Mini-cal after therapy in SNT group increased significantly in comparison with US group and were significantly higher than that before therapy in SNT group. Conclusion:SNT implemented by laypersons may effectively improve speech function in patients with aphasia and is a suitable method for family therapy. Objective:To explore the effects of semantic navigation training (SNT) applied by laypersons on improvement of solidification effect of vocabulary naming in patients with aphasia.Method:Twenty patients with aphasia were randomly divided into SNT group (n=10) and unrelated semantic (US) group (n=10). 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 SNT group and randomly without network analysis techniques in US group. All the patients with aphasia received speech therapy implemented by laypersons once a day for 10 consecutive days. Western Aphasia Battery (WAB) and the naming ability with 75 trained pictures were evaluated before and after therapy respectively in all the patients. The numbers of correct response and non-response were recorded in the end of training every day in order to draw the learning curve.Results:The number of correct response after training in SNT group was significantly higher than that before training in the same group and that after training in US group. The number of non response after training in SNT group were significantly lower than that before training in the same group and that after training in US group. The number of semantic description and no-word after training in SNT group were significantly lower than that before training in the same group. There was a significantly positive correlation between the number of correct response with 75 trained pictures and the naming score of WAB after training in SNT group. The numbers of correct response of trained items in SNT group were significantly higher than that in US group after the second day of training. The numbers of non response of trained items in SNT group were significantly lower than that in US group after the fifth day of training.Conclusion:SNT implemented by laypersons may markedly improve solidification effect of vocabulary naming and increase the learning efficiency in patients with aphasia. Objective:To explore the effects of semantic navigation training (SNT) applied by laypersons on improvement of generalization effect of vocabulary naming in patients with aphasia.Method:Twenty patients with aphasia were randomly divided into SNT group (n=10) and unrelated semantic (US) group (n=10). 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 SNT group and randomly without network analysis techniques in US group. All the patients with aphasia received speech therapy implemented by laypersons once a day for 10 consecutive days. Western Aphasia Battery (WAB) and the naming ability with 46 untrained pictures were evaluated before and after therapy respectively in all the patients.Results:The number of correct response, semantic substitution and semantic paraphasia after training in SNT 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 SNT group was significantly lower than that before training in the same group and that after training in US group. The number of semantic description and no-word after training in SNT group was significantly lower than that before training in the same group. There was a significantly positive correlation between the number of correct response with 46 untrained pictures and the scores in"yes or no"of comprehension of WAB after training in SNT group.Conclusion:SNT implemented by laypersons may markedly improve generalization effect of vocabulary naming in patients with aphasia.
