Speech and language disorders, which include swallowing difficulties, are usually managed by speech and language therapists. Such a diverse, complex and challenging clinical group of symptoms requires practitioners with detailed knowledge and understanding of research within those areas, as well as the ability to implement appropriate therapy strategies within many environments. These environments range from neonatal units, acute paediatric wards and health centres through to nurseries, schools and children’s homes. This paper summarises the key issues that are fundamental to our understanding of this client group.
