Book excerpt: Challenging Aphasia Therapies presents an entirely new approach to thinking on the subject of aphasia therapy by liberating it from traditional models. This is achieved through a process of reflection in which many assumptions previously taken for granted are challenged and reassessed. Internationally renowned experts successfully demonstrate the benefits of learning about aphasia therapy through the process of engaging in it. Topics covered include: * the role of context, culture and conversation in shaping and directing aphasia therapy * the ethical issues that arise from the current tensions between market driven health care industries and the moral commitment to their client welfare * the value of therapy. Contributors challenge the common notion of successful therapy as solely performance related. * the potential and competent use of humour in aphasia therapy. The identification of the strengths and limitations of clinical models and the focus on relevant directions for therapy will be of interest to practising clinicians as well as anyone involved in study or research in speech and language therapy.
