Decreased sensory nerve conduction velocity

What it means

Reduced speed of conduction of the action potential along a sensory nerve.

The sensory nerve action potential (SNAP) in response to electrical stimulation is recorded from the nerve itself by means of dermal recording electrodes. The SNAP is the sum of all the action potentials generated in sensory nerve fibers by the applied electrical impulse.

The range is how often this sign appears among people diagnosed with each disease — it is not a probability of having any of them. Many of these signs also occur in common, non-rare conditions. A sign on this page is a conversation to have with a clinician, not a conclusion.
