Table 2 Patterns of variability

1

Variability of FP on left versus right in the same nerve

2

Variability in the shape of FP between different nerves

3

Variability in the shape of FP at the same nerve and side over time

4

Variability of FP when serially stimulating distally versus proximally

5

Variability in the number of stimuli evoking a 1st CMAP

6

Variability in the number of stimuli to reach highest CMAP
