 Research into language therapy for aphasia has been conducted for many years. Recently, new trends in the rationale and strategies of aphasia therapy have been seen. In particular, "client-centered practice" as well as "evidence-based practice" have become influential philosophies in language therapy. Also, analyses of long-term recovery from aphasia and randomized controlled trial (RCT) research about language therapy have clarified the positive effects of language therapy for aphasia. Neurologically, investigation of neuroplasticity has developed, and new concepts of neural networks of language organized by cortical areas and white matter, such as the dual streams model (Hickok, 2004), have been proposed as the neural substrates of language. The development of these theories and brain imaging techniques facilitated the creation of novel therapeutic strategies such as noninvasive brain stimulation. Behaviorally, benefits of the intensive therapy for language improvement have been proved, and constraint-induced language therapy has been applied to aphasia. Furthermore, the social approach based on the conceptual framework of International Classification of Functioning, Disability and Health (ICF) has been widely used. In this review, these topics as well as the problems to be solved in aphasia therapy are discussed.
