A how-to-guide on the clinical assessment and investigation of patients presenting with muscle-related symptoms. Featuring a case-based approach, this accessible text is suitable for a wide range of clinical specialists who see patients presenting with both common and rare muscle diseases. Muscle diseases are often initially missed or misdiagnosed as they are uncommon disorders and can present in a variety of ways, often mimicking other more common disorders. Careful assessment of the history, physical examination and appropriate choice of investigations is therefore essential to reaching a diagnosis and providing short and long-term effective management plans. Key features of this resource include: - A case-based approach: using real cases seen in clinical practice and highlighting different clinical presentations. - Providing case vignettes that cover patient history, examination, investigations, diagnosis, and discussion points to assist the reader in developing a mental framework for thinking about muscle disease and approaching diagnosis. - Highlighting the relevant investigations (including muscle biopsy, neurophysiology, and muscle imaging) required for each clinical scenario, aiding the clinician in clinicopathological correlation. - Being concise, practical, and complemented by a wide range of figures to enhance understanding.

Patients with muscle diseases may be referred to one of several medical or surgical specialties including neurology, rheumatology, neuropathology, neurophysiology, cardiology, respiratory medicine, intensive care medicine, gastroenterology, ophthalmology, orthopaedic and spinal surgery, before the correct diagnosis is considered. This accessible text is an ideal resource for clinicians.
