摘要背景：研究表明，失语症（PWA）患者的手势可以传递对他们的交流有用的信息。然而，通过手势对信息交流的贡献的确切意义仍然不清楚。此外，仍然不清楚不同的手势类型和表示技术如何影响消息传递。目的：本研究旨在探讨手势对PWA沟通的影响。我们特别关注的程度不同的手势类型和表示技术传达信息的PWA的语音缺席。方法和程序：我们研究了46名PWA和9名非脑损伤参与者（NBDP）在半结构化会话中产生的手势。对于每一种不同类型的手势和表示技术，我们确定了这些手势和表示技术是否传达了必要的信息，即言语中不存在的信息。我们只关注基本的手势，而不是查看与语音中的信息相似或额外的信息。结果：对于PWA来说，他们五分之一的手势是必不可少的。尽管PWA之间存在个体差异，但大多数人比NBDP产生更多的基本手势，NBDP产生的基本手势数量有限。基本信息主要由特定的手势类型传达：指向，表情和图标手势。在一组标志性的手势中，不仅处理和制定，而且对象和形状手势，通常是必不可少的。结论：我们的研究结果表明，大部分PWA产生的手势传达的信息，理解他们的沟通至关重要。在他们的沟通建议中，言语治疗师可以提请注意特定的手势类型，以确保对话者在与PWA沟通时更多地注意这些手势。
ABSTRACT Background: Studies have shown that the gestures produced by people with aphasia (PWA) can convey information useful for their communication. However, the exact significance of the contribution to message communication via gesture remains unclear. Furthermore, it remains unclear how different gesture types and representation techniques impact message conveyance. Aims: The present study aimed to investigate the contribution of gesture to PWA’s communication. We specifically focussed on the degree to which different gesture types and representation techniques convey information absent in the speech of PWA. Methods & Procedure: We studied the gestures produced by 46 PWA and nine non-brain-damaged participants (NBDP) during semi-structured conversation. For each of the different types of gestures and representation techniques we identified whether these conveyed essential information, that is information that was absent in speech. Rather than looking at information that was either similar to information in speech or additional to information in speech, we focused on the essential gestures only. Outcomes & Results: For PWA, a fifth of their gestures were Essential. Despite individual differences between PWA, the majority produced more Essential gestures than NBDP, who produced limited amounts of Essential gestures. Essential information was mostly conveyed by specific gesture types: Pointing, Emblems and Iconic gesture. Within the group of iconic gestures, not only Handling and Enact but also Object and Shape gestures, were often Essential. Conclusions: Our findings suggest that a great proportion of gestures produced by most PWA convey information essential for understanding their communication. In their communication advice, speech language therapists could draw attention to specific gesture types to make sure that interlocutors pay more attention to these gestures when communicating with PWA.
