The aim of this study was to prove the efficacy of supervised self-training for individuals with aphasia. Linguistic and communicative performance in structured dialogues represented the main study parameters.
In a cross-over design for randomized matched pairs, 18 individuals with chronic aphasia were examined during 12 weeks of supervised home training. Intensive language training, assisted by an electronic learning device (B.A.Bar), was compared with nonlinguistic training. Language performance, communicative abilities, and cognitive abilities were controlled before and after each intervention and at follow-up. The language training was designed to facilitate dialogue skills as required in everyday life.
Robust and specific improvements in the participants' linguistic and communicative abilities were obtained using B.A.Bar dialogue training but not with nonlinguistic training. The transfer to general linguistic and communicative performance remained limited when the whole group was considered. For 30%-50% of the participants, individual analysis revealed significant improvements in spontaneous language and general communicative skills. Furthermore, individual participants demonstrated significant improvements regarding standardized aphasia assessment and proxy rating of communicative effectiveness.
Supervised home training works. This study has proven that it is an effective tool for bolstering linguistic and communicative skills of individuals with aphasia.
本研究旨在证明监督自我训练对失语症患者的疗效。在结构化对话中表现出的语言和交际能力是主要的研究参数。
在一项随机配对的交叉设计中，18 名慢性失语症患者在 12 周的家庭监督训练中接受了检查。强化语言训练，由电子学习设备（B.A.Bar）辅助，与非语言训练进行了比较。在每次干预前后和随访时都控制了语言表现、交际能力和认知能力。语言训练旨在促进日常生活中所需的对话技能。
使用 B.A.Bar 对话训练可显著提高参与者的语言和交际能力，但非语言训练则不能。当考虑整个组时，向一般语言和交际表现的转移仍然有限。对于 30%-50%的参与者，个体分析显示自发语言和一般交际技能有显著提高。此外，个别参与者在标准化失语症评估和交际效果代理评分方面表现出显著提高。
监督家庭训练有效。本研究证明了它是增强失语症患者语言和交际能力的有效工具。
