Transcutaneous electrical nerve stimulation of the occipital nerves as treatment for chronic cluster headache

Transcutaneous electrical nerve stimulation of the GON significantly reduced the frequency, intensity, and duration of weekly headache attacks in patients with severe CCH. Not all patients benefitted from TENS, but the treatment responders had a substantial improvement in their cluster headache. TENS treatment was well-tolerated with little or no side effects and could be a relevant supplement to conventional preventive treatment. A standard TENS apparatus is low cost, making the treatment accessible to most patients. This paper includes a detailed, comprehensive description of our clinical application of the therapy.
