Conditions
Summary
The goal of this clinical trial is to learn if catgut embedding works to treat chronic low back pain in adults with lumbar spondylosis and "Blood Stasis" syndrome. The main questions it aims to answer are: Does catgut embedding lower back pain more effectively than electro-acupuncture? Does catgut embedding improve the daily physical activities of participants? Researchers will compare catgut embedding to electro-acupuncture to see which method works better to reduce pain and improve quality of life. All participants will also receive counseling on lifestyle changes and back exercises. Participants will: Be randomly assigned to receive either catgut embedding (2 sessions over 4 weeks) or electro-acupuncture (20 sessions over 4 weeks). Visit the clinic for treatments and checkups. Complete surveys about their pain levels and ability to perform daily tasks at the start, at 2 weeks, and at 4 weeks.

Interventions
Participants receive catgut embedding therapy using polydioxanone (PDO) threads, size 29G x 30 mm. The procedure involves inserting the thread into acupoints including BL23, BL24, BL25, BL26, BL17, and SP10. The treatment is performed twice: at baseline (Week 0) and at Week 2
Participants receive acupuncture at 6 pairs of acupoints: BL23, BL24, BL25, BL26, BL17, and SP10. Electro-acupuncture: Applied to the 4 lumbar points (BL23, BL24, BL25, BL26) using the KWD-808-I device for 20 minutes. Manual Acupuncture: Applied to the remaining points (BL17 and SP10). Frequency: Once daily, 5 days per week, for 4 weeks
Both groups receive standardized guidance on daily lifestyle modifications and lumbar exercises. This includes instructions on correct sitting and standing postures, lifting techniques, and a specific set of stretching and strengthening exercises for the lower back to be performed at home.
