This book describes the problems that people can experience with their voices, either by vocal misuse, psychological and physical stress, laryngeal pathologies or neurological disorders. Chapters are contributed by clinicians who have special interest and expertise in voice disorders and their management and treatment. Two strong themes are clearly identifiable in each chapter: the first is the emphasis on the physiological aspects of phonatory dysfunction, and the second is the recognition that vocal impairments can have significant social and psychosocial consequences. Many of the contributors have also addressed issues such as evidence-based practice, efficacy and the outcomes of intervention. With each new edition of this book, the chapters have grown larger. Most original chapters have been rewritten or substantially updated, and several new chapters have been added by expert practitioners in the US, the UK and Australia. The editors have produced a balanced volume which will continue to be a useful reference text for all those practitioners and students who are involved in voice care.
