Sensory loss of function in MP and sensory gain of function in AD depends on clinical pain severity. Quantitative sensory testing (QST) profiles of the 3 tested areas, ie, most painful area (MP), pain-free area adjacent to MP (AD), and remote pain-free control area (CON) in a high-pain (clinical pain intensity ≥ NRS 4/10) (A) and a low-pain (clinical pain intensity < NRS 4/10) CLBP subsample (B). Data are presented as mean Z-values and SEs. CDT, cold detection threshold; CLBP, chronic low back pain; CPT, cold pain threshold; HPT, heat pain threshold; MDT, mechanical detection threshold; MPS, mechanical pain sensitivity; MPT, mechanical pain threshold; PPT, pressure pain threshold; TSL, thermal sensory limen; VDT, vibration detection threshold; WDT, warm detection threshold; WUR, wind-up ratio. ***P < 0.001.
