Drawing in aphasia therapy has been used predominately as a substitution for speech or to augment communication when other modalities are non-functional. The value of drawing as a route for facilitating verbal expression has not been a focus of prior research. We compared the usefulness of drawing and writing as compensatory strategies for improving naming in individuals with aphasia. Activation patterns of writing and drawing in healthy adults were examined using fMRI. Clinical results suggest that drawing facilitated naming whereas writing diminished accurate naming responses, and that drawing quality is not relevant to this facilitatory effect. Functional MRI findings revealed strong bi-hemispheric activation of semantic and phonological networks while drawing that may support our clinical findings.
在失语症治疗中，绘画主要被用作言语的替代方式，或者在其他交流方式无法起作用时用于增强沟通。绘画作为促进言语表达的途径，其价值尚未成为以往研究的重点。我们比较了绘画和书写作为补偿策略对改善失语症患者命名能力的有效性。使用功能磁共振成像（fMRI）检查了健康成年人书写和绘画时的激活模式。临床结果表明，绘画有助于命名，而书写则减少了准确的命名反应，并且绘画质量与这种促进作用无关。功能磁共振成像结果显示，绘画时语义和语音网络在双侧大脑半球有强烈激活，这可能支持我们的临床发现。
