背景：在健康的说话者中，手势经常伴随着说话。对于许多失语症患者来说，手势是言语语言病理学干预的目标，或者作为一种替代的交流形式，或者作为语言恢复的促进装置。失语症患者的手势产生模式和预测这些模式的参与者变量尚不清楚。目的：我们的目的是在大量失语症患者的会话话语中检查手势的产生。我们使用了一个详细的手势编码系统来确定与特定失语症类型和严重程度相关的手势产生模式。方法与步骤：我们分析了来自AphasiaBank的对话样本，这些样本来自46名中风后失语症患者和10名健康对照者，他们都在复述故事任务中至少做过一次手势。12种手势类型被编码。描述性统计用于描述手势产生的模式。通过方差分析（ANOVA）和多元回归分析来检验不同失语类型和严重程度的手势产生模式可能存在的显著差异，并检验这些潜在的手势产生模式的预测因素。结果与结果：失语症患者的手势明显多于健康对照组。失语症的类型和严重程度在特定的识别模式中对手势类型有显著影响，特别是在产生意义丰富的手势方面。结论：这些模式提示了手势作为失语症治疗目标的机会。失语流畅性比失语严重程度或命名能力更能说明数据的可变性。需要做更多的工作来描述预测因素。
Background: Gesture frequently accompanies speech in healthy speakers. For many individuals with aphasia, gestures are a target of speech-language pathology intervention, either as an alternative form of communication or as a facilitative device for language restoration. The patterns of gesture production for people with aphasia and the participant variables that predict these patterns remain unclear. Aims: We aimed to examine gesture production during conversational discourse in a large sample of individuals with aphasia. We used a detailed gesture coding system to determine patterns of gesture production associated with specific aphasia types and severities. Methods & Procedures: We analysed conversation samples from AphasiaBank, gathered from 46 people with post-stroke aphasia and 10 healthy matched controls all of whom had gestured at least once during a story re-tell task. Twelve gesture types were coded. Descriptive statistics were used to describe the patterns of gesture production. Possible significant differences in production patterns according to aphasia type and severity were examined with a series of analyses of variance (ANOVA) statistics, and multiple regression analysis was used to examine these potential predictors of gesture production patterns. Outcomes & Results: Individuals with aphasia gestured significantly more frequently than healthy controls. Aphasia type and severity impacted significantly on gesture type in specific identified patterns detailed here, especially on the production of meaning-laden gestures. Conclusions: These patterns suggest the opportunity for gestures as targets of aphasia therapy. Aphasia fluency accounted for a greater degree of data variability than aphasia severity or naming skills. More work is required to delineate predictive factors.
