This document addresses quantitative sensory testing (QST) used for the noninvasive evaluation of sensory nerve function in individuals with symptoms of, or the potential for, neurologic damage or disease. QST systems can assess and quantify the amount of physical stimuli required for sensory perception to occur. Various testing modalities used in QST can evaluate the sensory nerves involved in touch, pressure, pain, thermal (warm and cold), and vibration.

This document highlights two QST methods: threshold testing, also known as current perception sensory nerve conduction threshold testing, and pressure-specified sensory device testing.

Position Statement

Investigational and Not Medically Necessary:

Quantitative sensory testing including, but not limited to current perception threshold testing, also known as sensory nerve conduction threshold testing, and pressure-specified sensory device testing is considered investigational and not medically necessary.
