EMG findings in amyotrophic lateral sclerosis (ALS) commonly exhibit signs of denervation and spontaneous muscle activity.

EMG findings in amyotrophic lateral sclerosis (ALS) commonly exhibit signs of denervation and spontaneous muscle activity.

Correct answer is True: Electromyography (EMG) in amyotrophic lateral sclerosis often reveals characteristic signs of denervation, including fibrillation potentials and positive sharp waves. Spontaneous muscle activity may also be observed, reflecting the loss of motor neurons and subsequent neurogenic changes in the muscles. These EMG findings contribute to the diagnostic process and help differentiate ALS from other neuromuscular disorders.
