Figure 2From: Duration of observation required in detecting fasciculation potentials in amyotrophic lateral sclerosis using high-density surface EMGExamples of surface EMG signals recorded using the two electrode arrays. (A) Surface EMG signals recorded with the flexible electrode array from the thenar muscle. (B) Surface EMG signals recorded with the linear electrode array from the BB muscle. Channel 1 represents the most proximal channel.Back to article page
