Sham acupuncture (SA), also called placebo acupuncture (PA), performed away from the acupuncture points established by TCM or without stimulation and manipulation to avoid eliciting “De Qi” sensations or using a non-penetrating technique, is used as control in scientific studies to determine the efficacy of acupuncture. 6,7 However, in China, wrist-ankle acupuncture and abdomen acupuncture, both with …

These ‘non-specific’ outcomes include placebo responses (also sometimes called placebo effects), which we define here as the observed outcome changes in the sham groups. These changes are due to the natural history of the patient's condition or regression to the mean and a response to the ritual of medical treatments. Objective To investigate whether a sham device (a validated sham acupuncture needle) has a greater placebo effect than an inert pill in patients with persistent arm pain. Design A single blind randomised controlled trial created from the two week placebo run-in periods for two nested trials that compared acupuncture and amitriptyline with their respective placebo controls. Comparison of The physical placebo agent itself is a dummy treatment such as sham surgery, a sugar pill, and magnets. The placebo effect is the difference in mean treatment effect between sham and no treatment control conditions across two groups of patients or at different times within the same group of patients (crossover studies) (Fields & Price, 1997).

Differently from drugs, where a placebo is very simple to design, in active devices different scientific problems emerge which are often difficult to overcome. Our literature search yielded a total of 1738 references. Thirty-four studies met the inclusion criteria. The effects of sham (placebo) acupuncture varied according to the dermatomes stimulated: high overlap with those stimulated by verum acupuncture resulted in almost identical efficacy, while low overlap resulted in significant differences in efficacy. He also shared eye-opening insights on sham surgery, placebo effect studies, the economic drivers of medicine, and more.

2019-01-14 · Thus, many of the studies supporting acupuncture were not properly controlled and are, therefore, unreliable. In contrast, numerous studies that were controlled have found that sham (placebo) acupuncture is just as “effective” as regular acupuncture.

However, neither concept accounts for the great diversity of results in RCTs comparing verum acupuncture and sham (placebo) acupuncture. The American Society of Pain Management Nursing define a placebo as "any sham medication or procedure designed to be void of any known therapeutic value". In a clinical trial, a placebo response is the measured response of subjects to a placebo; the placebo effect is the difference between that response and no treatment.

Background: Placebo or sham controls are the standard against which the benefits and harms of many active interventions are measured. Whilst the components and the method of their delivery have been shown to affect study outcomes, placebo and sham controls are rarely reported and often not matched to those of the active comparator.
