What this trial studies

This clinical trial aims to compare the effectiveness of Pulsed Radiofrequency Ablation (PRF) versus Continuous Radiofrequency Ablation (CRF) in treating cervical facet joint-mediated pain, including neck pain, shoulder pain, and cervicogenic headaches. Eligible patients will be randomly assigned to one of the two treatment groups after undergoing medial branch blocks to assess their pain relief. The study will utilize a blinded approach for patients, with treatment success evaluated through questionnaires administered every three months. The recruitment process is expected to take 15-24 months, depending on the sample size achieved.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-90 with chronic cervical, shoulder pain, or cervicogenic headaches who have not found relief from previous treatments.

Not a fit: Patients who do not experience at least 50% pain relief after initial medial branch blocks will likely not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide patients with a more effective pain management option for chronic cervical and shoulder pain.

How similar studies have performed: Previous studies have shown varying success rates for radiofrequency treatments, indicating that while this approach has been tested, the specific comparison of PRF and CRF is novel.
