Auricular acupuncture associated with low-frequency laser in chronic low back pain: A randomized clinical trial

Abstract

Background

Low back pain is recognized as the leading cause of disability worldwide, affecting various populations and leading to social, psychological, functional, and economic consequences. Research into effective treatments for this condition is clinically relevant.

Objective

This study evaluated the effectiveness of auricular acupuncture combined with low-frequency laser therapy in treating chronic low back pain in primary care patients.

Design

A randomized clinical trial.

Participants

A sample of 104 individuals with chronic low back pain was divided into two groups: the experimental group (n = 52), which received four sessions of auricular acupuncture and low-frequency laser therapy (modified intravascular laser irradiation of blood), and the control group (n = 52).

Intervention

Participants were evaluated at the beginning and seven days after the last treatment session. Pain intensity was measured using a numerical pain scale, while the degree of physical disability was assessed using the Roland-Morris disability questionnaire. Quality of life was evaluated with the WHOQOL-BREF, and perceived self-efficacy in managing chronic pain was measured using the chronic pain self-efficacy scale.

Results

The experimental group showed significant reductions in pain intensity and improvements in physical disability, quality of life (specifically in health satisfaction, psychological well-being, and environmental factors), and self-efficacy in chronic low back pain management (all p < 0.0001).

Conclusion

Auricular acupuncture combined with low-frequency laser therapy was effective in reducing pain, improving physical disability, enhancing quality of life, and increasing self-efficacy beliefs related to chronic low back pain management.
