Asynchronous bilateral stimulation:
A)Reduces artifact

changes
This is termed interleaving stimulation and asynchronous bilateral stimulation, in which
one limb at a time can be stimulated and subsequently recorded. This allows
differentiation of left and right limbs. In contrast, synchronous bilateral stimulation of
left and right limbs would yield one waveform that represents both left and right
potentially allowing unilateral changes to go undetected.

going to stimulate the filum just to make sure it's not a nerve root. I won't generate a
CMAP from any muscles because it is not nerve. After making sure it's safe, he will cut it.
