This study explores the relationship between pain catastrophizing and outcomes following selective nerve root blockade (SNRB) in patients with lumbar radicular pain (LRP).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A prospective cohort study of 103 LRP patients, confirmed by MRI, was conducted. All participants underwent SNRB at Ume\u00e5 University Hospital. Outcomes were measured using PROMIS\u201029 and the Pain Catastrophizing Scale (PCS) at baseline and several intervals up to 84\u2009days post\u2010intervention. Patients were categorized into responder (\u226530% pain reduction) and non\u2010responder groups and stratified into three groups based on baseline PCS scores. Changes in outcomes from baseline to 14\u2009days post\u2010SNRB were analyzed in relation to PCS groups. PCS changes over time were evaluated between responders and non\u2010responders. Statistical analyses assessed PCS and outcome changes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Baseline pain catastrophizing was not a significant predictor of pain response to SNRB.

Addressing catastrophizing remains important but may serve better as an outcome measure rather than a predictor of treatment
