The 3rd edition of this book is a work of reference and guide for medical practitioners examining and treating spastic and dystonic movement disorders. The authors have chosen a highly practical approach and have included a large number of patients' photos to help memorise clinical conditions. In addition, numerous other fields of application have been developed for the drug botulinum toxin, e.g. urological, gastroenterological and gynaecological indications or pain (chronic migraine and other headaches, nerve compression syndromes). For this reason, this new edition has been supplemented by the new chapter "Vegetative Symptoms and Pain".
