Review Meta Analysis
Influence of greater occipital nerve block on pain severity in migraine patients: A systematic review and meta-analysis.
Greater occipital nerve (GON) block may be a promising approach to treat migraine. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the efficacy of GON block in migraine patients. ⋯ Compared to control intervention, GON block intervention can significantly alleviate pain, reduce the number of headache days and medication consumption, but have no significant influence on the duration of headache per four weeks for migraine patients.
