What Is The Neurometer Evaluation?

The Neurometer is a piece of diagnostic equipment that is used to evaluate the extent and severity of nerve dysfunction.

In order to evaluate the extent and severity of the problem and develop the most efficient treatment plan, an electro-diagnostic sensory Nerve Conduction Threshold (sNCT) study is performed. The sNCT evaluation generates neuroselective Current Perception Threshold values that quantify the functional integrity of both the large and small afferent nerve fibers.

The test is performed bilaterally to evaluate the physiological integrity of the peripheral nerves innervating the suspected dermatomes of impairment, as well as uninvolved adjacent control sites. The distribution of impairment permits the differentiation between sensory nerve impairment resulting from radiculopathic or compressive etiologies or a polyneuropathy of a toxic or metabolic etiology. This type of information is unavailable using conventional sensory Nerve Conduction Velocity (sNCV) measures.

Advantages of the sNCT study include the speed of the exam which commonly takes about an hour, the evaluation of all major subpopulations (large and small) of sensory nerve fibers and the painless detection of the earliest stages of radiculopathy (hyperesthesia) permitting earlier and more specific therapeutic intervention, as well as assisting in establishing an optimal treatment plan and documenting the outcome.
