Objective To observe the clinical efficacy of deep needling with long needles plus electroacupuncture in treating lower-limb pain due to lumbar intervertebral disc herniation (LIDH).Method Totally 139 patients with lower-limb pain due to LIDH were randomized into a treatment group of 76 cases and a control group of 63 cases. The treatment group was intervened by stimulating spinal nerve by deep needling with long needles (75 mm) plus electroacupuncture, while the control group was by conventional needling plus electroacupuncture. The Visual Analogue Scale (VAS) was observed before and after intervention, and the clinical efficacies were compared between the two groups.Result The total effective rate was 80.3% in the treatment group versus 57.1% in the control group, and the difference was statistically significant (P<0.05). The VAS scores were significantly changed after intervention in both groups (P<0.05). After intervention, there was a significant difference in comparing the VAS score between the two groups (P<0.05).Conclusion Deep needling with long needles plus electroacupuncture is an effective method in treating lower-limb pain due to LIDH.
