Pain phenotypes in people with chronic low back pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This cross-sectional observational study will classify chronic low back pain patients into pain phenotypes using a mechanism-based clinical algorithm. Participants undergo a detailed clinical history, quantitative sensory testing, and assessments of pain, disability, quality of life, and pain catastrophizing. The study also evaluates how reliably clinicians can apply the phenotyping method both within and between raters and compares clinical features across phenotype groups. Findings may support more personalized approaches to managing chronic low back pain. The research is conducted at Kutahya Health Sciences University in Türkiye and involves adults with at least 3 months of low back pain.
