Default Sensory and motor neuropathy?

I am a little confused.
As you know l have been diagnosed with sensory poly neuropathy.

Is it possible to have both sensory and motor?
Can sensory develop into motor? I suppose you are going to say everyone is different.
Do they normally go hand in hand?
Does it always start with sensory, or can one have just motor NP?


My neuro, when asked me to stand up from sitting said, l didn't use my hands toift myself and only my legs, which is a god sign, as it's mostly sensory NP and motor. In other tests for motor l was a little bit off.


Just your thoughts and your understanding on this would be great.

Default There are many people--

--with neuropathies described as "sensorimotor" in which the sensory component is considerably greater than the motor component.

Such a situation implies some compromise of a large, myelinated nerve (or nerves) that contain(s) both sensory (mechanical touch, vibration, position sense) and motor fibers. In such nerves, the sensory nerves tend to be more around the periphery of the nerve trunk (think telephone cable) and the motor fibers more to the center, so if the insult to the nerve involves a compressive component, the sensory tracts tend to be affected first, and to a greater extent.

And yes, people are different, individual to individual. Neuropathy symptoms that involve the small fibers are by definition sensory (and sometimes autonomic). Those that involve larger myelinated fibers can be sensory, motor, or mixed. A lot depends on the cause of the neuropathic insult.

I have kneck back pain in one area constantly. Even though x- ray shows only slight displacement, is it possible that the pain unseen in X-ray, could be the cause of my PN?

I asked Neuro, and he said no, l have a healthy looking spine on the X-ray.


What do your think.

Sue, I am no expert but neck pain being related to PN seems possible but as you are discovering nothing to do with nerves is simple.

Back/neck pain can be quite complex. For years I had chronic thoracic and sciatic back pain and went to the point of seeing specialists about surgery. While I have mechanical damage the turning point for me was reading a book by John Sarno. I still get occasional pain but I have come to realise that there are other factors that contribute to the pain and that I can do something about.

Default By the way--

--larger, myelinated nerves are more like the top telephone cable, though there are variations.

The motor fibers tend to be deeper "within" the cable.

Google Sarno's or TMS and you'll find lots of info. His theory isn't for everyone but if you have an open mind it makes a lot of sense and it worked for me.
