A prospective study of the association between pain and catastrophizing after selective nerve root blockade.

Introduction: Pain, comprising sensory and emotional elements, is influenced by pain catastrophizing, which magnifies pain and promotes helplessness and rumination. This study explores the relationship between pain catastrophizing and outcomes following selective nerve root blockade (SNRB) in patients with lumbar radicular pain (LRP).

Methods: A prospective cohort study of 103 LRP patients, confirmed by MRI, was conducted.
