QST: The Only Non-invasive Clinical Test
Quantitative Sensory Testing (QST) is essential in the evaluation of small-caliber A-delta & C-fibers, the primary transmitters of thermal & pain sensation. Small-fiber sensory nerves comprise over 70% of the body’s peripheral nervous system. Sensory Testing of the thermal senses is the only non-invasive clinical test, which quantitatively assesses the functional state of somatic small fibers from peripheral receptors through their central nervous system connections. As a complimentary test to traditional EMG/NCV, QST can demonstrate neurosensory abnormality when it is selective to the small fibers despite negative EMG/NCV findings, which evaluate large-caliber fibers only.
