Efficacy of Electroacupuncture Combined With Pregabalin in the Treatment of Trigeminal Herpetic Neuralgia: a Multicenter Randomized Controlled Trial Study Protocol

Trigeminal herpetic neuralgia is a common type of Zoster-associated Pain (ZAP), which troubles individuals in all ages and burdens society all over the world. Eleactroaupuncture (EA) is increasingly used in the treatment of ZAP due to its advantages such as low price, high safety, no adverse reactions, and high patient acceptance. Therefore, it is necessary to conduct randomized controlled trials to evaluate the effectiveness and safety of EA on ZAP and whether EA can be used as a substitute for pregabalin.
