Does sensory nerve respond preferentially to longer duration of stimulation?

Motor artifact can be an annoy to SNAP (antidromic sensory study). It was told that moving the recording electrode away from the muscle would minimize it. This worked when possible. 


I wonder if longer stim duration ( say 0.2 ms instead of default setting of 0.1 ms) while lowering the stimulation intensity (60% perhaps) would stimulate sensory fibers preferentially to motor fibers, hence lesser motor interference?

Why or why not? Thanks

I enjoy participating in the AANEM Connect Forum for a number of reasons. There are very fundamental questions posed on a frequent basis that cause me to pause and ask myself, ‘Why didn’t I think of that?’ Also, I continue to learn new things when others contribute their thoughts and experiences. Connect is an excellent opportunity for members to interact and to address any topic, including those that may not be discussed at an annual meeting or journal article.
