Details and patient eligibility

About

The aim of this study is to compare central and peripheric sensitization in headache patients at Baseline (T0) and 1 month after (T1) a treatment with an anti-CGRP (Fremanezumab-Ajovy).

Full description

20 patients and 20 healthy subjects will be enrolled. The headache patients will be recruited just before starting their treatment and 1 month after (corresponding to the efficacy peak). Hot and cold stimulations will be delivered with the ATS probe from the Medoc Pathway on the forehead and on the hand (palmar face) to determine painful threshold to warm/cold stimuli. A blink reflex will be generated with a concentric electrode placed over the eyebrow and with active/earth electrodes linked to the EMG machine for the recording. For the nociceptive flexion reflex, a cutaneous stimulation will be applied on the arm and the response recorded on the corresponding muscles.
