Retrospective cohort study evaluates pain response and opioid use in patients with chronic pain after PNS, suggesting further exploration is needed.

This study aims to evaluate the effectiveness of temporary percutaneous peripheral nerve stimulation for chronic pain management through longitudinal outcomes.
Retrospective cohort study of 125 patients treated with 60-day PNS at two hospitals from April 2021 to September 2025.
Primary outcome measured was pain reduction defined as ≥30% decrease in Numerical Rating Scale score postprocedure.
Analyses included longitudinal pain trajectories and sensitivity assessments for responder rates under different definitions.
24% of patients achieved ≥30% pain reduction from baseline to median postprocedural NRS score.
Responder rates varied from 8% to 14% based on sensitivity analyses and pain assessment methods.
Lead complications were more frequent among non-responders, and mental health comorbidities were high in the studied population.

Chiang et al. (2026) studied this question.
