Results
The study flow is shown in figure 1. Of 179 participants in the CHARM study, 173 provided baseline allodynia data and were included in this current study. Of these participants, 74.6% experienced cutaneous allodynia. Participants with cutaneous allodynia were mainly female and reported more often current anxiety symptomology, but did not differ on age, number of monthly migraine or headache days, age of onset, use of acute or prophylactic treatment, or current depressive symptomatology (Table 1). Of all participants, 27 (16%) did not experience any allodynia symptom at all, 79 (46%) experienced at least one cephalic allodynia symptom, and 67 (38%) experienced at least one extracephalic allodynia symptom. Almost all participants who experienced extracephalic symptoms, also experienced cephalic symptoms (65 (97%)). Divided into type of stimulus, 16 participants (9%) experienced only thermal allodynia symptoms, 16 (9%) only mechanical allodynia symptoms, and 114 (66%) both thermal and mechanical allodynia symptoms.
