Summary

Chronic low back pain (CLBP) due to lumbar spondylosis is a leading cause of disability, significantly impacting the quality of life in middle-aged and elderly populations. While electroacupuncture (EA) and auricular acupressure (AA) are recognized as safe, non-pharmacological therapies, high-quality clinical evidence specifically evaluating their combined effects on CLBP patients with TCM "Kidney Yin deficiency" syndrome remains limited.This randomized controlled trial aims to evaluate the efficacy and safety of combining EA with AA (utilizing Vaccaria segetalis seeds) compared to EA combined with sham AA. The study will focus on 76 eligible patients at Le Van Thinh Hospital. Primary objectives are to measure changes in pain intensity (VAS) and functional improvement (ODI) at three intervals: baseline (T0), after 7 days (T1), and upon completion of the 14-day intervention (T2). The findings are expected to provide an evidence-based foundation for an integrated treatment approach to manage chronic lumbar pain effectively.

Conditions

  • Chronic Low Back Pain (CLBP)
  • Lumbar Spondylosis

Interventions

DEVICE

Electroacupuncture

Using sterile, single-use 0.30x25mm needles, the investigator will perform acupuncture at Jiaji L2-S1 (Ex-B2), Shenshu (BL23), Weizhong (BL40), Sanyinjiao (SP6), and Fuliu (KI7). A reinforcing method will be applied with perpendicular insertion at a depth of 0.4 - 0.8 cm. After achieving the 'Deqi' sensation, needles will be connected to a KWD-808-I device to deliver a biphasic spike pulse (continuous wave) at a frequency of 100Hz for 20 minutes, with intensity adjusted to patient tolerance.

DEVICE

Auricular Acupressure

Using Vaccaria segetalis seeds at Shenmen (TF4), Subcortex (AT4), Lumbar spine (AH9), Kidney (CO10). The seeds are applied using skin-colored adhesive patches. The acupuncturist will manually press each ear point for 5 minutes during the electroacupuncture session (total 20 mins). Frequency: 1 session/day, 5 sessions/week, for 2 weeks.

DEVICE

Sham Auricular Acupressure

Using the exact same Vaccaria segetalis seeds and identical adhesive patches to ensure participants cannot visually or physically tell the difference from the real treatment. Seeds are placed at non-specific points: Anus (HX5), Shoulder (SF4), Lung (CO14), Tooth (LO1). The acupuncturist will manually press each point for 5 minutes (total 20 mins). Frequency: 1 session/day, 5 sessions/week, for 2 weeks.
