Comparison of the efficacy of repeated greater occipital nerve block and pulsed radiofrequency therapy in chronic migraine patients: a randomized controlled study

Study Overview

This study compared the effectiveness of two treatments for chronic migraines: greater occipital nerve (GON) block and pulsed radiofrequency (PRF) therapy.

Key Details

  • Participants: 70 patients with chronic migraines were included.
  • Methods: Patients were divided into two groups: one received GON blocks and the other received PRF therapy.
  • Assessment: Pain relief and disability were measured before treatment and at 1 month and 6 months after treatment.

Results

  • Both treatments significantly reduced pain scores after 1 and 6 months (p < 0.001).
  • The PRF group had lower pain scores than the GON block group at 6 months (p = 0.009).
  • Disability scores also improved significantly in both groups (p < 0.001).
  • The PRF group showed greater improvement in disability scores at 6 months compared to 1 month (p < 0.001).
  • PRF therapy was more effective than GON blocks in reducing disability at 6 months (p < 0.001).

Conclusion

Both GON block and PRF are safe and effective for treating chronic migraines, but PRF offers longer-lasting benefits.
