Effectiveness of Auricular Acupuncture for Migraine

Обзор

Migraine is a primary headache disorder characterized by recurrent episodes of moderate to severe pain, frequently accompanied by nausea, photophobia, and phonophobia. It ranks as the third most prevalent medical condition globally and is recognized by the World Health Organization (WHO) as one of the top ten causes of disability worldwide. Migraine presents substantial public health concerns due to its considerable socioeconomic burden and its detrimental impact on individuals' quality of life. Although pharmacological treatments are widely available, their effectiveness is often limited, with many patients experiencing inadequate symptom relief or adverse side effects. Consequently, there has been growing interest in non-pharmacological approaches, particularly acupuncture and auricular therapy, due to their favorable safety profiles and reported efficacy in alleviating migraine symptoms. Auricular therapy, a microsystem of acupuncture applied to specific points on the external ear, has gained popularity for its simplicity, low risk, and therapeutic potential. Despite its increasing clinical use, robust scientific evidence supporting the effectiveness of auricular therapy for migraine remains insufficient, underscoring the need for well-designed clinical studies to validate its therapeutic value.

Подробное описание

Migraine is a complex and dynamic neurological disorder characterized by fluctuations in attack frequency, duration, severity, and associated symptoms, necessitating timely prevention and effective management strategies. While pharmacological treatments remain the mainstay, their limitations have led to increasing interest in non-pharmacological interventions such as acupuncture. Acupuncture has gained global recognition for its efficacy, particularly in migraine, which is one of the conditions most responsive to this therapy. Supported by strong clinical evidence, acupuncture is considered safe and well-tolerated, with a low incidence of adverse effects. Guidelines for managing primary headache disorders now advocate a range of complementary approaches, including acupuncture, dietary changes, physical activity, and cognitive behavioral therapy which reflecting a paradigm shift towards integrative care. Clinical studies have demonstrated that acupuncture can significantly reduce migraine frequency, shorten attack duration, and alleviate symptom severity. Mechanistic research suggests acupuncture modulates migraine pathophysiology through neuroimmune and neurotransmitter regulation, although further studies are needed to elucidate its molecular effects, particularly beyond the trigeminovascular system. Within Traditional Chinese Medicine, auricular therapy based on stimulating specific points on the external ear aligned with internal organ systems via the "inverted fetus" model offers a simplified, non-invasive modality that activates neural signaling pathways to regulate bodily functions and relieve migraine symptoms. Despite its growing clinical use, further clinical evidence is needed to confirm the therapeutic efficacy and mechanisms of auricular acupuncture in migraine management.
