NCV Range numbers for 'Normal' Readings

[Guest guest]

Asheley, maybe some of this will help.

These are NCV Range numbers for 'Normal' range Readings taken from

my last NCV. Ask your doc to give you a copy of the findings - it

should look something like this - besides showing 'normal' range, it

should show what the conductions actually are. My last NCV was lower

extremities only including gluteus medius, gluteus maximus,

abductors, hamstrings, ilio-psoas, quadriceps, tibalis anterir,

peronei, extensor hallucis longus, tibalis posterior, extensor

digitorum brevis, abductor hallusis and medial and lateral gastroc.

Right Median Nerve

Motor distal latency (4.6 msec or less) mine was 3.7 msec

Conduction velocity (49.0 M/sec or more) mine was 59.2 M/sec

Sensory Distal latency (3.7 msec of less) mine was 3.3

Right Ulnar Nerve

Motor distal latency (4.0 msec or less) mine was 3.1 msec

Conduction velocity (49.0 M/sec or more) mine was 65.0 M/sec

Sensory distal latency (3.5 msec or less) mine was 2.4 msec

Right Peroneal Nerve

Motor distal latency (7.0 msec or less) mine was 4.8 msec

Conduction velocity (441.0 M/sec or more) mine was 61.2 M/sec

Right Sural Nerve

Sensory distal latency ( 4.2 msec or less) mine was 3.6 msec

My Electrodiagnostic Report also has a written section by the

examining doctor regarding the type of needle used, noting normal

irritability, with no fibrillatins or positive sharp waves... and on

to say 'more proximally, motor units were entirely normal in

frequency, amplitude, configuration and duration and there were no

fasciculations or abnormal discharges.

Following that, the examining doctor wrote a short narrative

under 'Comment' where he said the 'patient clearly does not have a

demyelinating or more common form of CMT in which slowed conduction

and frequently absent sensory potentials are observed. Moreover, the

patient did not show atrophy of the feet and hands as seen in CMT.

And bla bla bla.

But you get the idea. You should be able to at least to understand

what the examining doctor wrote in the NCV report 'Comment' section.

If you don't have this, get it. And ask all the questions to your

doc that you need to.
