Quantitative Sensory Testing in an Observational Cohort of Adults With Chronic Low Back Pain.

ABSTRACT: Quantitative Sensory Testing (QST), also known as psychophysical testing, includes standardized methods for assessing humans' perceptions of different types of sensory stimuli and their associated pain thresholds. QST results can be used to estimate altered or atypical sensory processing and thus can be useful for determining pain mechanisms such as nociplastic or central nervous system-mediated pain. The University of Pittsburgh Mechanistic Research Center, entitled, "Low Back Pain: Biological, Biomechanical, Behavioral Phenotypes (LB3P)," is part of the National Institutes of Health's Helping to End Addiction Long-term Initiative. LB3P conducted a prospective, observational cohort study to identify phenotypes of over 1000 participants with cLBP. QST was conducted on these participants as
