Low-Level Laser Therapy for Fibromyalgia: A Systematic Review and Meta-Analysis (2019)

This systematic review and meta-analysis evaluated whether low-level laser therapy (LLLT)/photobiomodulation (PBM) is effective for treating fibromyalgia, a chronic condition associated with widespread pain, fatigue, stiffness, and reduced quality of life. The analysis included randomized controlled trials comparing LLLT with placebo or control treatments.

Key findings:

• Pain reduction: LLLT significantly reduced pain intensity in fibromyalgia patients.
• Improved functional symptoms: Benefits were reported in fatigue, stiffness, and tender point sensitivity.
• Better quality of life: Some studies showed improvement in physical function and overall well-being.
• Safe and well tolerated: LLLT appeared to be a non-invasive treatment with minimal adverse effects.
• Adjunct therapy potential: PBM may help manage fibromyalgia symptoms alongside conventional therapies, not necessarily as a standalone treatment.

Conclusion:

The review concluded that LLLT appears to be an effective, safe, and well-tolerated therapy for fibromyalgia symptom management, particularly for pain relief and symptom improvement. However, the authors noted that differences in wavelength, dosage, treatment protocols, and study quality mean more standardized high-quality trials are still needed.
