"The book has been structured in a way that is useful to the reader, no matter their level of expertise in the field. I congratulate the authors on taking up the challenge of writing this book. It is clear, concise and grounded. One of the advantages of this book is that while it provides all of the theoretical information, it also provides illuminating case studies and challenging exercises which takes it out of the realm of theory and into the realm of practice"International Journal of Therapy and Rehabilitation, August 2009
