Muscle diseases (e.g. muscular dystrophy) form an important part of the neurologist's workload. This book is the latest edition of the most comprehensive single-volume reference work on clinical diseases of voluntary (skeletal) muscle. Recent advances in molecular biology have produced major changes in the diagnosis and classification of these diseases, edited and authored by a select team of experts from around the world, this edition has been extensively revised to cover these changes. Many chapters have been completely rewritten, and several entirely new chapters have been added to bring it right up to date with the latest developments.
