This comprehensive, groundbreaking book is an ideal companion to textbooks that focus on the theories behind articulation and phonological disorders but with little or no coverage of treatment options. It provides treatment strategies not only for the many sound system disorders with unknown etiologies, but also for those known to be caused by a structural, sensory, or neurological problem. It also discusses treatment for disorders caused by residual problems from early childhood. What sets this book apart is the inclusion of practical, step-by-step treatment strategies for all potential causes beyond those of unknown origin.
