Not sure if anyone here can help me understand this but I will post the "official results" right from the report .....Electromyogram Results:

1.Low amplitude right Peroneal motor response from
extensor digitorum brevis with slowed conduction velocity between popliteal fossa and ankle

2.Low amplitude right tibial motor response from abductor hallucis with slowed conduction velocity between popliteal fossa and ankle.

3.Normal right median motor response from APB with slowed conduction velocity between elbow and wrist.

4.Normal amplitude, right ulnar motor response from the hypothenar eminence with slowed conduction velocity between distal humerus and wrist.

5.Low normal amplitude in the right peroneal motor response from tibialis anterior with slowed conduction velocity across the fibular head.

6.Normal amplitude, right sural sensory response with slowed conduction velocity.

7.Absent right superficial peroneal sensory response.

8.Low amplitude right median sensory response from the second day (sic) with slowed conduction velocity across the wrist. The right ulnar fifth and radial first digit sensory responses are of normal amplitude and slowed conduction velocity.

9.Absent right medial and lateral plantar sensory responses.

10.Elevated right tibial H-reflex latency.

INTERPRETATION:

The above study is abnormal and is consistent with a length dependent sensory motor polyneuropathy. The patient's foot temperature was low as the time of testing; however, this alone does not explain the findings, which remain consistent with neuropathy.

Investigation into causes of neuropathy are recommended.

Hi, I'm sure you'll have more technical people respond..... but your test looks like mine did early on - a primarily sensory nueropathy with motor involvement too... I have absent sensory nerves and when the docs look at the biopsy done (I had a sural nerve - which shows large and small fibers - I believe a skin biopsy will show the same type damage but not small fiber biopsy?).... anyway, I have almost a complelete loss of large mylinated nerve fibers and also loss of some small mylinated (accounting for the sensory loss) - and also not such a drastic loss of unmylinated fibers both small and large, and nerve axon degerneration all through the nerve.... this confirmed the damage more conicisely then the NCS-EMG - of which I've more then a few - the expertise of the doc doing the test and their ability to interpret the results is very important.

In short, yes, sounds like you definately have a neropathy (and as your hands/arms are also affected) - "poly neuropathy"....

I've had most of the tests that have applied to these symtoms on the "lizajane" spreadsheets - tried IVIG - and finally have a diagosis of a genetic form of the disease... the important thing is now that your docs continue to do tests they can - if the cause can be found and treated in some way - you are way ahead of the game....

Hang in there - do you have appt to see neuro for more testing and discusss results??????

Thank you for the reply. Im still waiting for the appointment to be made. Hopefully I will hear something early next week.

OK...so I am assuming there is no demylination going on right? I assume if there was they would have put that in the interpitation.

Can I ask what if anything you have been diagnosed with?

Hi again,

I'm not sure from your tests - your doc I think would be able to tell.. I have total demylination in that the most of the nerve fibers with mylination on them just up and left town...... (I have no feeling on my skin on almost my whole body - just had an iv stick today and felt absolutely nothing).

The diagnosis I'm now getting is Hereditatry Sensory, Autonomic, and Motor Neropathy.. In the past they have suspected paraneoplastic (and still wont rule out completely) - and auto-immune PN's like Sjogrens - had a salivary gland biopsy - lots of blood work - and CIDP diagnosis even though the blood work and lumbar puncture didnt indicate it....

The autonomic portion affects my digestion (stomach doesnt work - "gastropareis") so live on fluids only and also my heart - but the heart problems are being controlled with meds at a satisfactory level for now..... just have to keep an eye on it....

Have you checked out the "stickies" at the top of the thread? Theres lots of great information and will help when you see the doc with questions, etc...

Not necessarily.
Your Dx sounds exactly like mine, and the small non-myleinated nerves as well as the large myleinated ones area affected, except that mine is axonal which means the axons are being attacked as well.
Testing should be done (see lizajane.com for a list) to determine cause, but it may be that you will be idiopathic without a cause being found. Be prepared for that. The treatment(s) are still the same, primarily.

I think Liza Jane's site is www.lizajane.org

I'll check it.

(yep, just checked it) That site is etched on my memory.

Other than some small reassurance that based on those test results SOMETHING IS WRONG. And, that it sounds as if your docs are moving on it. Albiet far too slowly for your tastes. That happens to all of us tho. I will say tho, once you get 'in the door'? You will be IN! My own nerve tests stated severely slowed to non-existent conductions and amplitudes. I've not had to have a skin biopsy as no one has suggested that, and refused outright the sural biopsy because the docs just seemed to eager to get it on their resumes [REALLY!] When all other test criteria had been met. I'd like to hold that one out as a very last resort when/if needed.
I think ages ago I posted something about 'interpreting' nerve studies, but it was all Greek to me other than the summary which, like yours, said: Not good.
DO keep in mind that you are very lucky in ways? Tho you mite not feel so.... in that it's been only a year plus and you are actually getting the plethora of testings you need! So many here and elsewhere have been shuttled around from doc to doc or been ignored while damage was being done-at least your docs are trying?! IN the meantime, pain is pain and usually constant, treatment is lame until a solid diagnosis and guess who suffers in the interim?
Be patient? Maybe the next time you call the neuro see if they can put you in a cancelled appt-that usually means you would have to go at the drop of a hat...but-
Hugs and hope and soon! -s - j

I have sensori-motor neuropathy too (mine is anxonal) which is caused by my lupus. I have posted recently about it (titled something like Sensori-motor neuropathy spreading to hands) so I won't repeat it all here.

nice to meet someone else with sensorimotor problems

cheers

Did you get a hold of the neuro? So what did they say the white spots are? Hope you are getting some answers and apts

Hi Raglet, nice to meet you. I'll pop over to your thread in a bit.

Hi Daniella, I have left messages but they never return my call. I have this beautifully written letter to fax off to my GP...called the office to get the fax number and their voice mail says they are on vacation until july 28th. Well that's only a week from Monday. I figure I've waited 16 months what's another week.

oh and the Neuro thinks the white spots are "microangiopathic in nature".....I think that means...relating to the blood vessels.
