Recent investigations into effects of intensity or distribution of aphasia therapy have provided moderate evidence supporting intensive therapy schedules on aphasia treatment response. The purpose of the present study was to investigate the feasibility of creating an intensive therapy session without extending the amount of daily time a person spends in treatment.
Individuals who presented with chronic anomia poststroke (N = 8) participated in 2 weeks of a computerized, therapist-delivered, cued, picture-naming treatment. Dosing parameters for each session were 8 presentations of 50 pictures, totaling 400 teaching episodes per session.
Of the 8 participants, 6 achieved significant increases from baseline on trained items after 400 teaching episodes (i.e., 1 treatment hr), and the remaining 2 participants achieved significant increases from baseline after 1200 teaching episodes (i.e., 3 treatment hr). Maintenance data from 7 of the participants indicated that 6 participants maintained significant improvement from baseline on trained items.
Given an intensive and saturated context, anomic individuals were surprisingly quick at relearning to produce problematic words successfully. Most participants demonstrated retention of the gains 2 months after treatment ended. The high density of teaching episodes within the treatment session (i.e., the intensive treatment schedule) may have contributed to the behavioral gains.
最近对失语症治疗强度或分布效果的研究提供了适度的证据，支持强化治疗方案对失语症治疗反应的作用。本研究的目的是探讨在不延长患者每日治疗时间的情况下开展强化治疗课程的可行性。
患有中风后慢性命名性失语的个体（N = 8）参加了为期2周的计算机化、治疗师指导、有提示的图片命名治疗。每个疗程的给药参数为50张图片展示8次，每个疗程共计400次教学环节。
8名参与者中，6名在400次教学环节（即1小时治疗）后，训练项目的基线水平有显著提高，其余2名参与者在1200次教学环节（即3小时治疗）后基线水平有显著提高。7名参与者的维持数据表明，6名参与者在训练项目上保持了相对于基线的显著改善。
在强化和饱和的环境下，命名性失语个体在重新学习成功说出有问题的单词方面出奇地快。大多数参与者在治疗结束2个月后仍保持了治疗成果。治疗课程中高密度的教学环节（即强化治疗方案）可能促成了行为改善。
