Effectiveness of deep electroacupuncture with strong deqi and shallow electroacupuncture with no deqi for lumbar disk herniation: study protocol for a randomised controlled trial

摘要

Lumbar disk herniation (LDH) is a common cause of low back pain and dysfunction. Studies have shown that electroacupuncture (EA) can achieve pain relief in patients with LDH. However, there is a lack of evidence regarding the effectiveness of deep EA with strong deqi and shallow EA with no deqi in patients with LDH. This study aims to evaluate the effectiveness of deep EA with strong deqi and shallow EA with no deqi in the treatment of LDH.
