Assessing pain processing changes in migraine patients with occipital nerve stimulation

Does Occipital Nerve Stimulation Alter Pain Response as Measured by Quantitative Sensory Testing in Patients With Chronic Migraine or Cluster Headache

Not applicable Interventional Barts & The London NHS Trust · NCT06022848

This study is testing how inserting an occipital nerve stimulator affects pain perception in people with chronic migraines or cluster headaches compared to those having a non-painful procedure and healthy volunteers.

What this trial studies

This study aims to evaluate how pain perception changes in patients with chronic migraines or cluster headaches before and after the insertion of an occipital nerve stimulator (ONS). It will compare these changes to patients undergoing a non-painful procedure under general anesthesia and to healthy volunteers. The study will utilize questionnaires and measure specific pain markers to assess the effects of ONS on pain processing. The research is conducted at Barts Health NHS Trust, focusing on understanding the underlying mechanisms of chronic headache disorders.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with intractable chronic migraines or cluster headaches who meet the criteria for ONS implantation.

Not a fit: Patients with conditions that preclude participation, such as diabetes or those who are pregnant, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients suffering from chronic migraines and cluster headaches.

How similar studies have performed: While neurostimulation techniques have been explored in other studies, this specific approach assessing pain processing changes with ONS is relatively novel.
