"Why I Am Skeptical of Acupuncture"
Controlled clinical trials of actual acupuncture (uncontrolled trials should only be considered preliminary and are never definitive) typically have three arms: a control group with no intervention or standard treatment, a sham-acupuncture group (needles are placed but in the “wrong” locations or not deep enough), and a real acupuncture group. Most of such trials, for any intervention including pain, nausea, addiction, and others, show no difference between the sham-acupuncture group and the acupuncture group. They typically do show improved outcome in both acupuncture groups over the no-intervention group, but this is typical of all clinical trials and is clearly due to placebo-type effects.
More recent trials have attempted to improve the blinded control of such trials by using acupuncture needles that are contained in an opaque sheath. The acupuncturist depresses a plunger, and neither they nor the patient knows if the needle is actually inserted. The pressure from the sheath itself would conceal any sensation from the needle going in.
