Transcutaneous and Percutaneous Neurostimulation for Headache Disorders

Area of Science:

• Neurology
• Neurosurgery
• Pain Management

Background:

• Noninvasive and minimally invasive extracranial stimulation are increasingly studied for primary headache disorders, especially migraine.
• Occipital and supraorbital stimulation devices present unique methodological challenges in research.

Purpose of the Study:

• To review the efficacy and safety of implantable occipital nerve stimulation (ONS) for primary headache disorders.
• To examine noninvasive supraorbital transcutaneous stimulation (NST) as a preventive therapy for episodic migraine.

Main Methods:

• Review of randomized, sham-controlled clinical trials for chronic migraine treatment using ONS.
• Exploration of methodological challenges in studying occipital and supraorbital stimulation devices.
• Literature review of NST for episodic migraine prevention.

Main Results:

• Efficacy and safety data for implantable ONS in chronic migraine treatment were analyzed from three randomized trials.
• Methodological considerations for studying occipital and supraorbital stimulation were identified.
• Evidence for NST as a preventive therapy for episodic migraine was reviewed.

Conclusions:

• Implantable ONS demonstrates potential for treating primary headache disorders, particularly chronic migraine.
• Noninvasive NST is a viable preventive therapy option for episodic migraine.
• Further research is needed to address methodological challenges in extracranial stimulation studies.
