“…However, stimulation of the LI4 acupoint with a metal needle will produce insufferable pain and is accompanied by whole-body reactions. Recently, the laser needle as an alternative method to manual acupuncture has been used in many studies because it is effective not only as a treatment method but also as a research tool [19,20,21]. It can simulate traditional acupoints while also reducing the stress effect resulting from metal needles.…”

Background: In the Yellow Emperor Neijing, it is stated that ‘if someone has a disease related with the left side, the treatment point is on the right side, and vice versa' [Unschuld PU: Huang Di Nei Jing Su Wen, 2003], which emphasizes that specific lateral-side acupoint stimulation might lead to therapeutic advantages under specific conditions. Methods: We summarize the different effects resulting from namesake acupoint stimulation referred to as acupoint laterality. In this short review, the evidence of acupoint lateralization from Neiguan (PC6), Hegu (LI4), and Quchi (LI11) is discussed. Results and Conclusion: Investigations indicate that acupuncture at the contralateral side of PC6 has different effects on heart rate variability (HRV), which means that PC6 has laterality. However, such a difference in HRV could not be observed when the same stimulation was applied to both sides of LI4, although the difference in blood perfusion distribution was confirmed exactly. Considering the results from PC6, we hypothesize that acupoint laterality might be related to acupoint specificity. Although the evidence is not clear, our results indicate that in patients with hypertension, different-side LI11 stimulation can also produce different results, which might indicate that acupoint laterality is associated with the functional state of subjects. The perspective of acupoint lateralization is also preliminarily discussed in this review. i 2014 S. Karger AG, Basel

“…Beside subjective and objective data that there is also a clear deqi sensation evoked by laser acupuncture, another related study published recently by our group is of particular interest [24]. In this study, we reported small, but reproducible human cerebral evoked potentials after bilateral, nonperceptible laser needle (658 nm, 40 mW, 500 μ m, 1 Hz) irradiation of the Neiguan acupoint (PC6).…”

Deqi, a composite of unique sensations, is essential for clinical efficacy according to Traditional Chinese Medicine. It is described as a sensory perception of varying character and is mostly ascribed to metal needle acupuncture. However, it can also be elicited by different kinds of laser acupuncture stimulation. This short paper summarizes the current scientific status of deqi in laser stimulation. Different kinds of laser acupuncture are described in a comprehensive form, and the most interesting studies concerning deqi and laser acupuncture are presented.

“…Compared with a metal needle, laser acupuncture does not pierce skin and has always been considered to have no therapeutic effect as well as no evocation of de qi. However, in some study reports published in 2012, researchers have demonstrated that subjects with laser acupuncture also experienced de qi [32–34]. On the basis that de qi is the sign of acupuncture efficacy these studies signify that using laser acupuncture as an intervention in the control group may cause underestimation of acupuncture effects.…”

De qi is a core concept of acupuncture and is necessary to produce therapeutic effect. In 2010, de qi has been received as a term in the official extension of the CONSORT Statement. However, there are few articles that discuss which factors have influences on obtaining de qi in clinical trials. This paper aims to explore these factors and give advice on trial design in order to optimize de qi in acupuncture RCTs.
