Variability of excitability measures in motor axons

	Same subject, within experiment	Same subject, different days	Between subjects (n= 6)
TEd40(peak) (%)	0.8 (1.1%)	1.4 (2.2%)	4.8 (7.3%)
TEh100(peak) (%)	8.2 (2.4%)	23 (6.8%)	79 (19.8%)
TEh100(260–300 ms) (%)	5.5 (1.9%)	18 (6.3%)	81 (24.1%)
RRP (ms; geometric SD)*	1.026	1.06	1.198
Superexcitability (%)	1.2 (5.2%)	1.5 (6.9%)	7.05 (35.8%)
Superexcit. area (% ms)	−12.5 (8.8%)	−16.4 (12.1%)	−65.4 (46.9%)

Figures are for the standard deviation and the coefficient of variation is in parentheses. *RRP – geometric standard deviation (as a factor).
