[Electrotherapy for headaches]

Area of Science:

• Neurology
• Medical History

Background:

• Neuromodulation is increasingly used for drug-resistant headache.
• Electrotherapy for headache treatment has historical roots dating back to ancient times.

Observation:

• Historically, static electricity was used for various neuropsychiatric disorders, including headache, during the 18th and 19th centuries.
• The efficacy of early electrotherapy was debated, with skepticism regarding placebo effects.

Findings:

• Electrotherapy for headache saw a decline in the early 20th century but has recently resurged.
• The debate on electrotherapy's efficacy continues alongside its modern application.

Implications:

• This historical review underscores the necessity of placebo-controlled studies for evaluating electrotherapy in headache treatment.
• The findings emphasize the importance of robust study designs for assessing neuromodulation techniques in various neurological disorders.
