Fasiculations
The term muscle
fasiculations refers to visible or palpable twitching of small groups of muscle
fibers. It can occur in one or more muscles. Fasiculations can develop
secondary to a variety of causes including compromise of the spinal cord,
compromise of one or more spinal nerve roots, peripheral nerve damage, and with
muscle disease. Electrolyte abnormalities and certain metabolic disorders can
also result in muscle fasiculations. Recurrent muscle fasiculations accompanied by muscle atrophy
and/or spasticity is often the result of progressive neurological compromise.
