Laser acupuncture for depression: a randomised double blind controlled trial using low intensity laser intervention

Area of Science:

• Integrative Medicine
• Neuroscience
• Psychiatry

Background:

• Acupuncture research for depression yields inconsistent findings.
• Investigating novel therapeutic modalities for major depressive disorder is crucial.

Purpose of the Study:

• To evaluate the efficacy of laser acupuncture versus placebo laser acupuncture for treating major depressive disorder.
• To compare objective and subjective measures of depression severity.

Main Methods:

• A randomized, double-blind, placebo-controlled trial involving 47 participants with DSM-IV major depressive disorder.
• Intervention involved 12 sessions of laser or placebo acupuncture over 8 weeks.
• Primary outcome: Hamilton-Depression Rating Scale (HAM-D); Secondary outcomes: QID-SR and QIDS-CL.

Main Results:

• Active laser acupuncture demonstrated statistically significant improvements in HAM-D and QIDS-CL scores compared to placebo.
• Response rates were 72.0% for laser acupuncture vs. 18.2% for placebo.
• Remission rates were 56.0% for laser acupuncture vs. 4.5% for placebo.

Conclusions:

• Laser acupuncture provides a clinically and statistically significant benefit in reducing depression symptoms.
• The treatment shows potential as an effective intervention for major depressive disorder.
• Further research is needed to explore long-term effects and optimal treatment protocols.
