目的：在这项研究中，作者评估了在对失调症的强化治疗中增加有意的左手手势如何影响两种类型的话语：图片描述和对开放式问题的回答。方法：14名失语症患者完成了失调症的治疗，共30次治疗，为期3周。结果：两组受试者在训练项目和非训练项目的命名方面均有显著变化，但在西方失语症电池-失语商(WAB-AQ；Kertesz，1982)得分方面没有变化。话语的改变仅限于3个月的随访评估。一些语篇测量显示，图片描述任务有显著的改善，而在回答问题时则有所下降。此外，手势组在每次评估中产生的单词更多，而非手势组在每次评估中产生的单词更少。这些模式导致了手势组图片描述的改善和问题回答的最小下降。相反，与训练前相比，无手势训练组在图片描述和问题回答方面的改善微乎其微。结论：强化治疗方案是一种成功的方法，即使是在未训练的项目上也能提高图片命名。此外，作者得出结论认为，有意的左手手势对话语处理的泛化有显著的贡献。
Purpose: In this study, the authors assessed how the addition of intentional left-hand gestures to an intensive treatment for anomia affects 2 types of discourse: picture description and responses to open-ended questions.Method: Fourteen people with aphasia completed treatment for anomia comprising 30 treatment sessions over 3 weeks. Seven subjects also incorporated intentional left-hand gestures into each treatment trial.Results: Both groups demonstrated significant changes in trained items and improved naming of untrained items but no change in Western Aphasia Battery-Aphasia Quotient (WAB-AQ; Kertesz, 1982) scores. Changes in discourse were limited to the 3-month follow-up assessment. Several discourse measures showed significant improvements in the picture description task and declines during question responses. Additionally, the gesture group produced more words at each assessment, whereas the no gesture group produced fewer words at each assessment. These patterns led to improvements in picture descriptions and minimal declines in question responses in the gesture group. In contrast, the no gesture group showed minimal improvements in picture descriptions and production declines in question responses relative to pretreatment levels.Conclusion: The intensive treatment protocol is a successful method for improving picture naming even of untrained items. Further, the authors conclude that the intentional left-hand gesture contributed significantly to the generalization of treatment to discourse.
