Quantitative sensory testing (QST) is a psychophysical assessment of somatosensory system that complements neurological
sensory examination. The information derived from QST presents the function of unmyelinated C-fibers, small myelinated
Aδ-fibers, and large myelinated Aβ-fibers including their central pathways to the brain. QST may be performed by simple
bedside method and by standardized method developed from the German Research Network on Neuropathic Pain (Deutscher
Forschungsverbund Neuropathischer Schmerz, DFNS). The standardized QST makes it possible to subgroup patients with
peripheral neuropathic pain of different etiologies according to sensory profiles with emerging evidence showing predictive
value of QST for treatment efficacy.
