The current literature reflects the interest of pediatricians, neurologists, and internists in the neuromuscular disorders of childhood.1-5 Clinical awareness and the availability and refinement of ancillary procedures, such as electromyography, measurement of nerve conduction velocities, determination of serum enzymes and muscle biopsies, have made it possible to differentiate many of these conditions and correctly localize the pathology of these lower motor neuron disorders to the anterior horn cells, the peripheral nerves, and/or the muscles.1
Primary muscle disease is the most frequent cause of progressive muscular weakness in children with neuromuscular disorders.2 The primary myopathies are either hereditary or acquired. The muscular dystrophies and the myotonic syndrome are representative of the genetic variety, while the acquired disorders are recognized clinically as polymyositis and dermatomyositis.
