Bilateral LE tibial and fibular motor responses were normal, but elicited only upon increasing the PW to 200-700 us, and 100 mA (patient insensate so not painful). Bilateral superficial peroneal and sural responses were absent, H-reflexes absent, fibular F wave absent. Tibial F waves normal.
Needle EMG was normal.
What is the significance, if any, of the requirement of strong stimulation to elicite a normal motor response in this setting?
Thank you,
Robert

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.
