Detection of Fasciculation Potentials in Amyotrophic Lateral Sclerosis Using Surface EMG
Wide presence of fasciculation potentials is an important indicator for supporting diagnosis of amyotrophic lateral sclerosis (ALS). This study describes the use of surface electromyography (EMG) techniques for examination of fasciculation potentials in ALS patients. Multi-channel surface electrode arrays were used for fasciculation potential recording, while template matching techniques were used to discriminate whether the recorded fasciculation potentials were from the same or different motor unit origins. The results were assessed using independent processing of selected channels of electrode array surface EMG signals.
