Referred cutaneous allodynia in a migraine patient without simultaneous headache.

چکیده
Cutaneous allodynia has been described in migraine. We report on a 39-year-old woman with migraine with aura who had cutaneous allodynia to both dynamic (brush) and static (pressure) mechanical stimulation between attacks. For both sensory modalities, the evoked pain on allodynia testing was located to the right frontal area (the location of her usual migraine headache), contralaterally to the stimulated skin area. There was no allodynia when the right frontal area was stimulated directly. We suggest the term 'referred allodynia' for this phenomenon and discuss possible mechanisms for its occurrence.

OBJECTIVE To evaluate the effect of GONB, with or without trigger point injection (TPI), on dynamic mechanical (brush) allodynia (BA) and on head pain in migraine. Background.-Patients with migraine often have cutaneous allodynia that is related to sensitization of central pain neurons. Greater occipital nerve block (GONB) is an effective treatment for migraine headache; however, its effect on ...
متن کاملIdentifying cutaneous allodynia in chronic migraine using a practical clinical method.
Cutaneous allodynia is common in migraine. In the majority of previous studies on allodynia in migraine, only patients with episodic migraine (EM) were included. Little is known on patterns of allodynia in chronic migraine (CM). Since the presence of allodynia is associated with a poor response to triptans, a clinically practical method to test migraine patients for allodynia would be useful to...
متن کاملThe development of cutaneous allodynia during a migraine attack clinical evidence for the sequential recruitment of spinal and supraspinal nociceptive neurons in migraine.
Recently, we showed that most migraine patients exhibit cutaneous allodynia inside and outside their pain-referred areas when examined during a fully developed migraine attack. In this report, we studied the way in which cutaneous allodynia develops by measuring the pain thresholds in the head and forearms bilaterally at several time points during a migraine attack in a 42-year-old male. Prior ...
متن کاملComparison of dynamic (brush) and static (pressure) mechanical allodynia in migraine.
Allodynia has been described in migraine but has not been fully investigated for the different sensory modalities. The aim of this study was to compare the prevalence of dynamic (brush) and static (pressure) mechanical allodynia in migraine patients and to suggest a practical method of testing them in a clinical setting. Patients with International Headache Society-defined episodic migraine (EM...
متن کاملCutaneous allodynia is more frequent in chronic migraine, and its presence and severity seems to be more associated with the duration of the disease.
Objective To evaluate cutaneous allodynia among patients with chronic and episodic migraine in a tertiary headache clinic. Methods 80 subjects with episodic migraine and 80 with chronic migraine were assessed in a tertiary hospital. The 12-item Allodynia Symptom Checklist/Brazil questionnaire was applied to classify subjects according to the presence and severity of cutaneous allodynia. Res...
