In the largest study to date of blockade of the greater occipital nerve for migraine treatment, more than half of patients claimed a 50% reduction in pain.
Blockade of the greater occipital nerve is routinely used to treat acute migraine headache although there is a dearth of conclusive clinical evidence to support the procedure. The current study sought to assess the efficacy of the intervention with a focus in pain relief as the primary outcome. While the study has its limitations, it is a meaningful contribution to the body of evidence in support of a peripheral mechanism underlying migraine etiology.Get a top-line look at the study and its results in the short slide show above.Source: Allen SM, Mookadam F, Cha SS, et al.
