A study evaluated the effectiveness of three different placebo acupuncture methods to see how well they can blind the therapeutic effects of real acupuncture in healthy volunteers.
The research involved 321 participants who were randomly assigned to groups receiving various acupuncture and placebo techniques, and assessments were conducted to measure perceptions of the treatments.
Results showed no significant differences in participants' beliefs about whether they received real or placebo acupuncture, suggesting that different methods may not effectively blind individuals to the treatment they received.
