Fibrillation potentials and fasciculations are often also present with electromyography.
2.
The two most common pathologic types of resting activity in muscle are fasciculation and fibrillation potentials.
3.
Alpha motor neuron lesions also result in abnormal EMG potentials ( e . g ., fibrillation potentials ) and fasciculations, the latter being spontaneous, involuntary muscle contractions.
