Effect Of Audiovisual Gesture Combined With Phonological Component Analysis On Naming Ability Of Non-fluent Aphasia And Intervention Study

Patients with non-fluent aphasia can cause naming disorders due to brain damage involving the nervous system related to oral expression,which can be manifested as unresponsiveness or naming errors.Some patients develop tonal errors,which are superphonemic abnormalities.Phonological component analysis is a phonetically-developed approach to the treatment of naming disorders that aims to reconstruct subvocabulary,phonetic sequence knowledge,and phonological awareness,but does not take tone into account.In Mandarin Chinese,tone is expressive and plays an important role in naming ability,so it is necessary to incorporate tonal factors into phonological component analysis for interventions in Mandarin Chinese-speaking patients.Audiovisual and gesture stimulation,as forms of stimulation for tonal interventions,help activate multisensory pathways in patients with non-fluent aphasia and thus promote their speech output.Therefore,this study aims to explore the effect of different stimulus forms combined with phonological component analysis on the naming ability of patients with non-fluent aphasia,and then formulate an intervention strategy of audiovisual gesture combined with phonological component analysis in patients with non-fluent aphasia,and verify its clinical effect through a single group of experimental studies before and after testing.The content of this study is divided into two parts,the specific research content is:1.Study 1: The experimental design of single-factor repeated measurement was used to compare the effects of three different forms of stimulation,such as audio-visual,gesture,and audiovisual gesture,combined with phonological component analysis on the naming ability of 15 patients with non-fluent aphasia.The results showed that the main effect of different stimulus forms combined with phonological component analysis on the naming ability of patients with non-fluent aphasia reached a very significant(P<0.001)or significant(P<0.05).After the intervention of audiovisual gesture stimulation combined with phonological component analysis,the naming accuracy rate and tone accuracy rate in the naming related tone parameters were significantly increased(P<0.001)or significantly(P<0.05),among which the K value of the slope of the second and fourth tones and the K value of the third tone were significantly increased(P<0.001),indicating that audiovisual gestures combined with phonological component analysis could improve the naming ability of patients with non-fluent aphasia.After the intervention of audiovisual and gestural stimulation combined with phonological component analysis,the slope of one tone and the K reduction of three tones showed a significant improvement trend(P<0.05),indicating that the audiovisual form could improve the output of patients with one tone and three tone K reduction.In conclusion,the above results show that audiovisual gesture stimulation combined with phonological component analysis is more favorable to the output of most tones in this type of patients,and has a promoting effect on the overall naming ability.2.Based on the above research results,Study 2: Based on the above research results,a strategy of audiovisual gesture combined with phonological component analysis of patients with non-fluent aphasia was proposed,and verified by a single group of preand post-test experiments.The results showed that:(1)After 2 weeks of intervention by audiovisual gestures combined with phonological component analysis strategy,the naming accuracy rate and tone accuracy rate of patients were significantly improved(P<0.001)or significantly improved(P<0.05);(2)In terms of objective parameters of naming-related tones,except for one tone,the ability of patients in two,three,and four tones was significantly or significantly improved(P<0.001,P<0.05,P<0.05).The innovation of this study is reflected in the analysis of audiovisual gestures combined with phonological components of non-fluent aphasia based on experimental results,which are characterized by:(1)improving the phonological components analysis of tonal content according to the characteristics of tonal language;(2)Integrate the form of audiovisual stimulation,and map the information of speech samples through audiovisual feedback;(3)Left-handed gesture to target tones as auxiliary training.Using audiovisual gestures as the stimulation form of intervention and improving the naming ability of patients through multi-channel stimulation,this strategy has certain practical guiding value for the clinical application of patients,and enriches the theoretical significance of using tone as the connection point for the intervention of naming disorders in patients with non-fluent aphasia.
