Energy Healing: Meta-Analysis
Summary
Jain and Mills conducted a systematic review examining the evidence for biofield-based energy healing therapies including Reiki, Therapeutic Touch, Healing Touch, and External Qi. The review summarized randomized controlled trials assessing outcomes. It reported suggestive evidence of benefit for pain and anxiety in some patient populations, though study quality was variable, heterogeneity was substantial, and potential publication bias could not be ruled out.
Key findings
The review found suggestive evidence that biofield therapies may reduce pain intensity and anxiety in some populations, with limited evidence for fatigue and quality of life. Evidence was strongest in studies with weaker designs; higher-quality trials tended to show smaller or null effects. No specific biofield mechanism was demonstrated. Blinding of practitioners is impossible and participant blinding is difficult, which biases results toward placebo responses.
Methodology
The review applied standard systematic review methods. Studies were selected based on randomization, use of a control group, and clearly defined outcomes. Methodological quality was formally appraised.
Criticism / Limitations
The authors noted that many included studies had small sample sizes and methodological weaknesses. The heterogeneity across different energy healing modalities made it difficult to draw conclusions about any single practice. The inability to adequately blind participants remains a fundamental limitation for this entire research area.
Verification notes
The finding of suggestive effects that diminish with higher study quality is consistent with the interpretation that energy healing effects are largely attributable to placebo and therapeutic contact. The review is widely cited in discussions of energy medicine evidence.
