My CIDP Record 2000 through 2026 of Nerve Conduction Studies (NCS)
CIDP nerve conduction studies (NCS) + CIDP electro-diagnostic electromyography (EMG)

My first nerve conduction study (NCS) October 8, 2002 (aged 56-years) was "pristine" albeit I reportedly had "very high amplitude sensory responses". I underwent this fist NCS because I felt something was wrong including a left leg and foot that very occasionally would suddenly begin to drag. April 18, 2008 (aged 62-years), nerve conduction studies by my principal doctor were "suggestive of axonal neuropathy" and CIDP was mentioned but it was reported by the doctor that he did "not have great electrodiagnostic evidence of a primary demyelinating lesion". A second NCS opinion four months later, August 5, 2008, was suggestive of "sensory more than motor polyneuropathy of most likely a demyelinating nature" (but no conduction block was reported). Then almost two years later on May 05, 2010 my condition was revised by my principal doctor to "exceedingly mild CIDP"

 

In 2015 when I was first transferred to the CIDP Clinic at Toronto General Hospital the Nerve Conduction Studies conclude my "nerve conduction study and needle examination show evidence of demyelinating polyneuropathy affecting the lower limbs". Motor and sensory studies of median nerve are normal. Motor studies of left peroneal and tibial nerves show low CMAP, prolonged distal latencies, and slow conduction velocity. Since a study of left sural nerve shows slow conduction velocity. F waves of left median nerve are normal but prolonged and left peroneal and tibial nerves. Vibration perception thresholds are prolonged in the lower limbs. Needle EMG examination show evidence of denervation potentials in left tibialis anterior and gastrocnemius muscles, normal and vastus lateralis."

(I had n 2019 started to myself look more closely at my NCS results but found my doctors reluctant to provide them In 2026 it is somewhat different as I am more insistent on obtaining the data and also the doctors I believe realized they are actually obligated to provide them. I am very much an amateur on such an analysis but I will be posting the results on CIDPlog I hope early 2026).
