efficacy study of acupuncture in the prevention of migraine without aura

Conditions: Migraine Without Aura

Summary: acupuncture is commonly used for the prevention of migraine, while the evidence for its efficacy is still uncertain. current studies have not been able to determine whether the efficacy of acupuncture is due to the actual therapeutic effect of acupuncture, or a result of psychological benefits. to address this issue, we designed a clinical trial to evaluate the prophylactic efficacy of acupuncture for migraine without aura (mwoa). furthermore, we will evaluate the impact of chinese medicine factors and psychological factors on the efficacy of acupuncture.

this is a multicentre, stratified, randomized, sham-controlled clinical trial. 150 eligible participants will be randomly allocated into verum acupuncture, sham acupuncture, or usual care groups, in a 2:2:1 ratio. the verum acupuncture group will receive twenty verum acupuncture treatments over an eight-week period, while the sham acupuncture group will receive sham acupuncture treatments with non-penetrating needling. participants assigned to the usual care group are scheduled to receive twenty verum acupuncture treatments for free after waiting 24 weeks. health education will be provided to participants in the three groups. the primary outcomes will be the changes in the mean number of migraine days and migraine attacks per four-week cycle. the secondary outcomes will be as follows: the proportion of responders, migraine intensity, migraine disability assessment questionnaire, health-related and sleep-related quality of life, the dose of intake of acute medication. chinese medicine factors will include de qi sensations and traditional chinese medicine (tcm) constitution. psychological outcomes will include anxiety, depression, personality, expectancy about acupuncture, and doctor-patient relationship. the central randomization and data collection will be conducted by an electronic data management system.
