Muscle wasting, fasciculations and fibrillations are typically signs of end-stage muscle denervation and are seen over a longer time period. Another feature is the segmentation of symptoms – only muscles innervated by the damaged nerves will be symptomatic.
Muscle atrophy, fasciculations, and fibrillations are generally indicative of terminal muscle denervation and are observed over a longer duration. Another characteristic is the compartmentalization of symptoms – only muscles supplied by the damaged nerves will exhibit symptoms.
