RT Book, Section A1 Amato, Anthony A. A1 Russell, James A. SR Print(0) ID 1115657609 T1 Disorders of Motor Nerve Hyperactivity T2 Neuromuscular Disorders, 2e YR 2015 FD 2015 PB McGraw-Hill Education PP New York, NY SN 9780071752503 LK neurology.mhmedical.com/content.aspx?aid=1115657609 RD 2024/04/24 AB Complaints referable to muscle such as pain, spasm, stiffness, fatigue and/or abnormal movements within a muscle are commonplace in the practice of medicine. As the cause is often elusive, both patients and physicians may become frustrated as many with these complaints will remain undiagnosed despite thorough investigation. There are many sources for this diagnostic elusiveness. With the exception of cramps and fasciculations, the disorders described in this chapter are uncommon. In addition, most of the disorders that will be described have nonspecific and overlapping clinical features. Successful diagnosis requires a heightened index of clinical suspicion, detailed knowledge concerning each disorder's phenotypic characteristics, and awareness of the serologic and electrodiagnostic (EDX) features of each syndrome.
