Characterization of Fasciculation Potentials (FPs) in Amyotrophic Lateral Sclerosis (ALS) and Peripheral Nerve Hyperexcitability Syndromes (PNH)

Table 1

Demographic characteristics and fasciculation detection rate in muscles of ALS and PNH.

	ALS ()	PNH ()
Gender (M : F)	27 : 9	10 : 9	0.388
Age (years)	59.6 (8.2)	54.0 (14.8)	<0.001
Disease duration (month)	15.6 (10.6)	20.0 (31.3)	<0.001
ALSFRS-R	39.8 (5.5)	N/A	N/A
Overall fasciculation detection rate (%)	45.1 (163/361)	53.2 (66/124)	<0.001

The data of age, disease duration, and ALSFRS-R were shown as the mean (SD). ALS: amyotrophic lateral sclerosis; PNH: peripheral nerve hyperexcitability syndrome; and ALSFRS-R: revised ALS Functional Rating Scale.
