Aphasia is prevalent in people following stroke, which can have a significant impact on the quality of life of the patients with stroke. One of the new methods for treatment of patients with aphasia is constraint-induced aphasia therapy (CIAT). The aim of this study was to investigate the efficacy of CIAT on naming deficits in individuals with chronic aphasia. This study had a prospective, single-subject study with A-B-A design. The CIAT was administered to two patients with chronic aphasia. Participants were a 57-year-old male and a 45-year-old female and had a stroke 60 and 36 months ago, respectively. In this study, the naming test was used as the outcome measure. The naming test was administered in three baseline sessions with 1 week interval between tests (phase A). Patients received CIAT for four consecutive weeks (3 days/week). Four measurements were taken during the treatment phase (phase B). In follow-up phase (phase A) two other measurements were performed. Visual analysis consisting of level, regression line, and variability were used to determine the effects of CIAT on naming. Both participants increased scores on naming test after phase A and B. The mean of the naming score improved from the baseline to the intervention phase in both participants. There was a positive trend in naming scores during the treatment phase compared with the trend in the baseline demonstrated by both participants. The results of this study showed that the CIAT can be effective in improving the naming deficit in patients with chronic post-stroke aphasia.
失语症在中风患者中很常见，这会对中风患者的生活质量产生重大影响。治疗失语症患者的新方法之一是强制性失语症治疗（CIAT）。本研究的目的是调查CIAT对慢性失语症患者命名缺陷的疗效。本研究采用前瞻性单受试者A-B-A设计。CIAT应用于两名慢性失语症患者。参与者分别是一名57岁男性和一名45岁女性，分别在60个月和36个月前中风。在本研究中，命名测试用作结果指标。命名测试在三个基线阶段进行，测试之间间隔1周（A阶段）。患者连续四周接受CIAT治疗（每周3天）。在治疗阶段（B阶段）进行了四次测量。在随访阶段（A阶段）进行了另外两次测量。使用包括水平、回归线和变异性的视觉分析来确定CIAT对命名的影响。在A阶段和B阶段后，两名参与者的命名测试得分均有所提高。两名参与者从基线到干预阶段的命名得分平均值均有所提高。与两名参与者在基线阶段的趋势相比，治疗阶段的命名得分呈上升趋势。本研究结果表明，CIAT对改善慢性中风后失语症患者的命名缺陷有效。
