Fasciculations are observed in patients with neurogenic disorders and
in healthy individuals. Depending on the associated clinical symptoms
and signs, they may signify the presence of a variety of disorders of
the lower motor neuron. Divergent and occasionally conflicting opinion
s prevail regarding the aetiology, pathogenesis, clinical significance
, neurophysiological characteristics and the physiological site of ori
gin of fasciculations. In this review we examine the published literat
ure and attempt to clarify these issues. (C) 1997 Elsevier Science B.V
