Table 1. Motor profile of the pre-symptomatic and symptomatic SOD1(G93A) mice.

	4-6 weeks old		12-15 weeks old
	WT	SOD1(G93A)	WT	SOD1(G93A)
n (mice)	16 (9M, 7F)	11 (5M, 6F)	10 (4M, 6F)	10 (6M, 4F)
Body weight (g)	19 ± 0.72	18 ± 0.95	24 ± 0.93	24 ± 0.89
LF at 5 rpm (s)	242 ± 13.4	262 ± 14.0	267 ± 12.3	246 ± 23.6
LF at10rpm (s)	257 ± 11.8	236 ± 21.8	263 ± 13.9	181 ± 31.3#

The values are mean±SEM. Results obtained from aged-matched SOD1(G93A) and WT mice were compared (#p<0.05, Mann-Whitney test). LF, latency-to-fall; rpm, rotations-per-minute
