Abstract
The objective of this observational study is to report clinical and instrumental results obtained in 23 chronic migraine sufferers treated with transcutaneous neurostimulation with the Cefaly(®) device. The electrom yography (EMG) parameters of the patients monitored before and during neurostimulation with the Cefaly(®) device showed a significant increase in the EMG amplitude and frequency values in the frontalis, anterior temporalis, auricularis posterior and middle trapezius muscles. The Cefaly(®) device could act on the inhibitory circuit in the spinal cord thus causing a neuromuscular facilitation and may help reduce contraction of frontalis muscles.
