[Therapeutic intervention in infantile autism and generalized developmental disorders: self-injury and self-stimulation].

INTRODUCTION: In this article we present a review of the aetiology and treatment of self-injury and self-stimulation in infantile autism and in generalized development disorders. We summarize 20 years of study and investigation in the treatment of these serious behaviour disorders, in a pioneer institution in Spain: the centre for rehabilitation 'El Cau' in Castellon. DEVELOPMENT: We describe the most frequent behaviour disorders, with particular reference to self-injury and self-stimulatory behaviour. Models explaining the aetiology and treatment are described in a brief general review of the subject, and we consider explicative models which integrate different treatments (in family and institutional contexts) by means of family therapy, psychoeducational models and social support networks.
