ABSTRACT

Background: Many individuals with aphasia (IWA) experience sentence production deficits (SPD), which can affect their daily interactions. Even if distinct treatments have been developed to improve these deficits, their efficacy is not always thoroughly measured, which makes it difficult to determine the optimal treatment for a given IWA. Objective: The primary objective of this study is to analyse the efficacy of the treatments that have been proposed for SPD in terms of gains on trained items, generalization to untreated items, maintenance of the acquired gains, and transfer to other contexts. Methods: A systematic review was conducted across the following databases: PubMed, CINHAL, and LLBA. Results: Twenty-five studies met criteria for this review, regrouping 11 different SPD treatments and 84 IWA. Different types of treatment were found. They mainly target verbs, sentence structures, or morphology. Concerning efficacy, gains on trained items and generalization to untreated items were demonstrated for almost every treatment, whereas the other efficacy measures were not always reported or improved. IWA characteristics and intensity treatment variables were also analysed for each treatment. Conclusions: No matter whether they focus on verbs, sentence structures, or morphology, most of the analysed treatments seem to be effective for improving SPD in IWA. Through various treatments, efficacy seems to be dependent on IWA’s characteristics such as time post-stroke and aphasia severity.

摘要

背景：许多患有失语症 (IWA) 的人会出现造句缺陷 (SPD)，这会影响他们的日常互动。即使已经开发出不同的治疗方法来改善这些缺陷，它们的疗效并不总是得到彻底的衡量，这使得很难确定给定 IWA 的最佳治疗方法。目标：本研究的主要目的是分析针对 SPD 提出的治疗方法在训练项目上的增益、对未处理项目的泛化、获得性增益的维持以及转移到其他环境方面的有效性。方法：对以下数据库进行了系统评价：PubMed、CINHAL 和 LLBA。结果：25 项研究符合本次审查的标准，重新组合了 11 种不同的 SPD 治疗和 84 种 IWA。发现了不同类型的治疗方法。它们主要针对动词、句子结构或词法。关于疗效，几乎每一种治疗都证明了训练项目的收益和对未处理项目的推广，而其他疗效措施并不总是报告或改进。还针对每种治疗分析了 IWA 特征和强度治疗变量。结论：无论是关注动词、句子结构还是词法，大多数分析的治疗方法似乎都能有效改善 IWA 中的 SPD。通过各种治疗，疗效似乎取决于 IWA 的特征，例如中风后时间和失语严重程度。而其他疗效指标并不总是得到报告或得到改善。还针对每种治疗分析了 IWA 特征和强度治疗变量。结论：无论是关注动词、句子结构还是词法，大多数分析的治疗方法似乎都能有效改善 IWA 中的 SPD。通过各种治疗，疗效似乎取决于 IWA 的特征，例如中风后时间和失语严重程度。而其他疗效指标并不总是得到报告或得到改善。还针对每种治疗分析了 IWA 特征和强度治疗变量。结论：无论是关注动词、句子结构还是词法，大多数分析的治疗方法似乎都能有效改善 IWA 中的 SPD。通过各种治疗，疗效似乎取决于 IWA 的特征，例如中风后时间和失语严重程度。
