BACKGROUND: The randomized controlled trial (RCT) is considered the 'gold

standard' methodology for evaluating efficacy of an intervention. It has

been argued that RCTs cannot be used to examine the effectiveness of

acupuncture. PURPOSE: The purpose of this paper is to examine the

applicability of an RCT study design for acupuncture research. FINDINGS:

RCTs would be more effective in studying acupuncture if study participants

were randomized to groups based on the acupuncture diagnosis and not solely

on the Western diagnostic criteria. Treatments must also be standardized

somewhat to ensure replicability of the study and the information it

provides. Blinding is not absolutely necessary for a good-quality RCT;

however, if used, control groups need to be standardized and sham techniques

evaluated to ensure accurate interpretation of results. CONCLUSIONS: With

these factors combined, it is possible to greatly increase internal and

external validity in acupuncture RCTs.
