Transcutaneous Auricular Vagus Nerve Stimulation Combined With Cervical Epidural Injection for Cervical Radiculopathy
China80 participantsStarted 2026-04-10
Plain-language summary
This is a prospective, randomized, double-blinded, sham-controlled trial conducted to investigate the efficacy and safety of transcutaneous auricular vagus nerve stimulation (taVNS) combined with cervical epidural injection in the treatment of cervical radiculopathy. A total of 80 subjects will be enrolled and randomly assigned (1:1) to either the experimental group or the control group. The primary outcome measure is the proportion of subjects with a ≥50% reduction in the Numerical Rating Scale (NRS) pain score at discharge. Secondary outcomes include pain intensity, pain interference, psychological status, sleep quality, physical disability, and autonomic function measurements. Adverse events will be monitored throughout the study.
