Demographic and clinical features of the subjects.

	Control subjects (n = 98)	ALS subjects (n = 404)
Age in years	56.75 ± 15.91	63.05 ± 11.48			p <0.001
Gender	w = 49, m = 49	w = 167, m = 237			n.s.
		Training	Test
		(n = 98)	(n = 306)
Disease duration in months		19.25 ± 17.63	18.66 ± 7.16	n.s.
ALS-FRS		39.04 ± 22.81	39.64 ± 6.98	n.s.

Values are mean ± SD. Significance was tested using the t-test for age, disease duration, and ALS-FRS, and the Fisher exact test for gender. ALS-FRS, ALS functional rating scale (11). n.s., not significant (p > 0.05).
