Exploring the interplay between pain processing mechanisms, psychosocial factors, and functional outcomes in patients with chronic low back pain: an exploratory study

Pain intensity in patients with CLBP correlates with central sensitisation, psychological distress, and functional limitations. PPT and STS60 may serve as valuable clinical indicators of pain severity and functional impairment, respectively. These findings support a multidimensional assessment framework for CLBP, integrating sensory, psychological, and functional factors to inform comprehensive treatment strategies.
