It's organized by disease states and includes chapters on diagnostic and management tools of particular relevance, including muscle and nerve biopsy, EMG and nerve conduction studies, neuromuscular genetic testing, and rehabilitation interventions of particular relevance to this patient population. New to this edition are a section on neuromuscular ultrasound, a listing of validated outcome measures and functional scales in neuromuscular disease, interim advances in treatments, advances in understanding of mechanisms of disease, an expanded section on symptom and disability management, a single source listing outcome measures and functional scales, and a discussion on the growing importance of neuromuscular ultrasound and MR imaging. An indispensable guide for neurology residents and fellows, neuromuscular medicine fellows starting their training, practicing neurologists, and providers in related fields that have high exposure to neuromuscular disease populations.
