Abstract

Objective. To investigate the short- and long-term effects of electroacupuncture EA compared with medium-frequency electrotherapy MFE on chronic discogenic sciatica. Methods. One hundred participants were randomized into two groups to receive EA or MFE for 4 weeks. A 28-week follow-up of the two groups was performed. The primary outcome measure was the average leg pain intensity. The secondary outcome measures were the low back pain intensity, Oswestry Disability Index ODI, patient global impression PGI, drug use frequency, and EA acceptance. Results. The mean changes in the average leg pain numerical rating scale NRS scores were 2.30 1.86–2.57 and 1.06 0.62–1.51 in the EA and MFE groups at week 4, respectively. The difference was significant . The long-term follow-up resulted in significant differences. The average leg pain NRS scores decreased by 2.12 1.70–2.53 and 0.36 −0.05–0.78 from baseline in the EA and MFE groups, respectively, at week 28. However, low back pain intensity and PGI did not differ significantly at week 4. No serious adverse events occurred. Conclusions. EA showed greater short-term and long-term benefits for chronic discogenic sciatica than MFE, and the effect of EA was superior to that of MFE. The study findings warrant verification. This trial was registered under identifier ChiCTR-IPR-15006370.
