Anomia affects numerous persons with aphasia. Treatment effects of anomia group therapy have been reported, but the evidence is not comprehensive. This study aimed to explore treatment effects of a naming treatment compared with a non-naming treatment delivered in a group setting.
In a randomized controlled trial, 17 participants with chronic poststroke aphasia underwent group therapy, 2 hours a session, 3 times per week, for a total of 20 hours. The treatment given in the naming group was modified semantic feature analysis (SFA). Treatment content in the non-naming group comprised auditory comprehension, copying text, and reading. The primary outcome measure was accuracy in confrontation naming of participant-selected trained nouns and verbs. Generalization effects were evaluated in single-word naming, connected speech, and everyday communication.
Participants in both groups significantly improved their naming of trained items. There were no differences between the groups. The treatment effect did not remain at follow-up 10 weeks after therapy. No other statistically significant changes occurred in either group.
Group intervention can improve naming ability in individuals with chronic aphasia. However, similar treatment effects can be achieved using a non-naming treatment as using a naming treatment, such as modified SFA. Further research is warranted to identify the most important elements of anomia group therapy.
命名障碍影响众多失语症患者。已有关于命名障碍团体治疗效果的报道，但证据尚不全面。本研究旨在探讨在团体环境中进行命名治疗与非命名治疗的效果差异。
在一项随机对照试验中，17 名慢性脑卒中后失语症患者接受了团体治疗，每次 2 小时，每周 3 次，共 20 小时。命名组接受的治疗为改良语义特征分析（SFA）。非命名组的治疗内容包括听觉理解、文本抄写和阅读。主要结局指标为参与者选择的训练名词和动词的命名准确性。在单字命名、连续言语和日常交流中评估了泛化效果。
两组参与者的训练项目命名能力均显著提高。两组间无差异。治疗后 10 周随访时，治疗效果并未持续。两组均未出现其他有统计学意义的变化。
团体干预可以改善慢性失语症患者的命名能力。但是，使用非命名治疗（如改良 SFA）也可以达到类似的治疗效果。需要进一步研究以确定命名障碍团体治疗的最重要要素。
