[Muscle cramps: mechanism , etiology and current treatment].
Spasms of skeletal muscles occur in healthy individuals or in the course of functional disorders of the peripheral motor neuron or its axons. Like fasciculations, they are a motor manifestation, but a painful one. Cramps evoke the notion of ephapsis and of immature terminal axons. There are, however, also other responsible regulatory systems, mostly the sensible and spinal ones. Three personal observations are used to illustrate the various triggering mechanisms. A review of the literature on this subject is added. Symptomatic treatment has not changed over past decades: Quinidine remains the treatment of choice. Other stabilizers of cell membranes are actually available, whose usefulness varies as a function of the cause of cramps.
