Background To establish efficacy in acupuncture treatment, rigorous randomized controlled trials (RCT) are needed. Non-invasive sham acupuncture needles are an effective tool for practitioner/participant blinding. This study presents a protocol for the validation of a newly developed sham acupuncture needle.
Methods A double-blind RCT will be conducted on 66 healthy adults who will be randomly assigned (using computer-generated random numbers) to either the verum (n = 33) or sham (n = 33) acupuncture needle group. The needles will be inserted at 2 acupuncture points: LI4 (upper limb) and ST36 (lower limb). The primary outcome measure is the practitioner/participants belief that they received verum or sham acupuncture. The secondary outcome measures are participant-rated sensations (penetration, pain, and de qi). Adverse events will be recorded with detailed explanations, categorizing occurrences according to related or unrelated to acupuncture. As the newly developed sham acupuncture has not been studied before, an exploratory approach has been adopted. Descriptive statistics, t test, and χ² test will be applied appropriately.
Results This study is intended to provide a protocol for the validation of a sham acupuncture needle by using a double-blind RCT setting, and the results will hopefully contribute to the standardization of the needles used for sham acupuncture. The outcomes aim to determine the reliability of practitioner/participant blinding, participant experience of sensations, and lay groundwork for a standardized control group for clinical trials in the future. The newly developed non-invasive sham acupuncture needle may reduce bias and improve reliability in the size effect of acupuncture treatment.
Background Streitberger and Park sham needles have been developed and used as non-penetrating sham acupuncture needles that can be blinded in randomized controlled clinical trials assessing the efficacy of acupuncture. Ideal sham acupuncture should not be distinguishable from an actual acupuncture treatment provided to the experimental group to ensure patient blinding; additionally, it should not have any physiological or biological effect. Providing evidence for such sophisticated sham acupuncture devices is critical, as control settings in clinical studies are based on research verifying their validity.
Methods Three core electronic databases - PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials - will be used to search for validity verification studies of sham acupuncture devices. Clinical studies that verify the validity of non-penetrating sham acupuncture devices will be included in the review.
Results The study design, participant information, experimental and control groups, study population’s experience with acupuncture, outcome variables, and results of studies that verify the validity of sham acupuncture devices will be systematically reviewed.
Conclusion This systematic review of validity verification studies of sham acupuncture devices is expected to help the development of more sophisticated sham acupuncture, as well as the design of studies verifying its validity in the future.
