The Safety of Laser Acupuncture: A Systematic Review

Area of Science:

• Integrative and Complementary Medicine
• Acupuncture Research
• Clinical Safety Studies

Background:

• Laser acupuncture is gaining popularity, particularly for patients with needle phobias, children, and the elderly.
• Existing literature on the safety of laser acupuncture is limited.
• A comprehensive review of safety data is necessary.

Purpose of the Study:

• To systematically review and synthesize available literature on the safety of laser acupuncture.
• To assess adverse events associated with laser acupuncture therapy.

Main Methods:

• A systematic search of multiple databases (Ovid MEDLINE, Embase, Scopus, Cochrane) was conducted.
• Randomized controlled trials (RCTs) investigating laser acupuncture were included.
• Safety data, including adverse events (AEs), their severity, and causality, were extracted and analyzed.

Main Results:

• Twenty-one RCTs were included in the review.
• The majority of studies reported laser acupuncture as safe with no AEs.
• Six trials reported mild, transient AEs (tingling, pain flare-ups, fatigue) that resolved within 24 hours.

Conclusions:

• Laser acupuncture appears to be a safe therapeutic option with a low incidence of mild, transient adverse events.
• Further large-scale, well-designed, placebo-controlled RCTs with robust evaluation methods are required for a more complete safety assessment.
