Abstract
This paper aims to review the literature on the therapeutic approaches employed for the treatment of verb tense inflection in individuals with agrammatic aphasia and the reported outcomes on language production and verb tense inflection. All studies on the treatment of verb tense inflection were found by searching Cochrane library, ISI Web of Knowledge, Google Scholar, Pubmed, and Scopus until December 2020, with the combination of these keywords, ‘aphasia, verb, morphology, tense, therapy, treatment, rehabilitation’. All studies (single-case or group design) on the treatment of verb tense inflection in individuals with acquired aphasia were reviewed. Data were synthesized descriptively through tables to allow the facilitated comparison of the studies. The methodology of the reviewed studies was assessed using single-case experimental designs (SCED) scale. An adaptation of the Cochrane Collaboration's risk of bias (RoB) tool was employed to evaluate the risk of bias (RoB) in the reviewed studies. A total of 14 studies were selected and reviewed. The results of the reviewed studies demonstrated that the remediation of tense morphology production in individuals with agrammatic aphasia is effective and verb tense marking can be improved by therapies that specifically target this disorder. This review highlights the need for a more systematic investigation of different types of treatments for tense marking. Also, more detailed information about the treatment of regular vs irregular verbs are required to elucidate the potential efficiency of these two verb types in the treatment of tense inflection. Overall, regarding the theoretical and clinical aspects, the number of studies that specifically target tense morphology are growing and based on the positive potential of these treatments, they could be suitable for the rehabilitation of people with aphasia, especially those with agrammatism.
本文旨在综述有关语法性失语症患者动词时态屈折的治疗方法以及在语言产生和动词时态屈折方面的报道结果。截至2020年12月,通过检索Cochrane图书馆、ISI Web of Knowledge、Google Scholar、Pubmed和Scopus,结合关键词“失语症,动词,形态学,时态,治疗,治疗,康复”,找到所有关于动词时态屈折治疗的研究。本文回顾了所有关于治疗获得性失语症患者动词时态屈折的研究(单例或组设计)。通过表格对数据进行描述性综合,以便对研究进行比较。所回顾研究的方法学采用单例实验设计(SCED)量表进行评估。采用Cochrane协作网(Cochrane Collaboration)的偏倚风险(risk of bias, RoB)工具来评估所回顾研究的偏倚风险(risk of bias, RoB)。本研究共选取并回顾了14项研究。综述的研究结果表明,对语法性失语症患者的时态形态产生的修复是有效的,动词时态标记可以通过专门针对这种疾病的治疗来改善。这篇综述强调需要对不同类型的紧张标记处理进行更系统的研究。此外,还需要更多关于规则动词和不规则动词处理的详细信息来阐明这两种动词类型在处理时态屈折时的潜在效率。总的来说,在理论和临床方面,专门针对时态形态的研究越来越多,基于这些治疗的积极潜力,它们可能适用于失语症患者的康复,特别是那些有语法障碍的人。
期刊介绍:
The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
