Abstract

Objectives: To assess the therapeutic effects and adverse effects of PDO thread embedding combined with electroacupuncture and the oral use of Liu Wei Di Huang decoction in the treatment of chronic lower back pain due to lumbar disc degeneration at the Traditional Medicine Hospital in Ho Chi Minh City.

Subjects and method: 74 patients were randomly divided into 2 groups, with 37 participants in each group. The research group: PDO threads were embedded in acupoints BL23, BL24, BL25, BL26 combined with electroacupuncture. The control group: Sham PDO threads were embedded combined with electroacupuncture. Patients were treated with thread embedding (or sham) every 2 weeks for 4 weeks, followed by an additional week of follow-up. Both groups also received electroacupuncture and herbal decoctions. Outcomes were assessed using VAS and RMDQ at 1, 2, 4, and 5 weeks. Adverse events that occur during the course of the trial were recorded.

Results:  After 5 weeks, the research group had a VAS score reduction from 7.87 ± 1.1 to 2.43 ± 0.95, while the control group had a reduction from 7.71 ± 0.83 to 3.74 ± 1.41 (p<0.001). The proportion of patients with good pain relief in the research group was 70.3%, higher than the control group (24.3%) (p<0.05). The RMDQ score significantly decreased in the research group, from 16.8 ± 4.26 to 2.5 ± 2.9, compared to the control group (from 16.7 ± 4.32 to 6.8 ± 4.4) (p<0.001).

Conclusions: PDO thread embedding combined with electroacupuncture is more effective in reducing pain and improving lumbar spine function compared to electroacupuncture alone. No adverse event occurred.
