Acupuncture manipulation is one of the key factors affecting the performance of acupuncture in Traditional Chinese Medicine. Lift-thrust and twirl-twist are two of the most commonly used manipulation methods for needle acupuncture. We previously have developed a novel laser acupuncture model that emulates lift-thrust operation. In this study, we intend to show the effectiveness of such a model by applying it on the Neiguan acupoint (PC6). Stimulation was reported to be beneficial for improving cardiac output and peripheral circulation. Therefore, we hypothesized that the stimulation of laser acupuncture may increase the temperature of the subjects’ fingertip due to increased peripheral blood flow. A thermal imager was used to measure the temperature change of subjects’ fingertips. Through regression analysis, it has been shown that while PC6 is stimulated, laser acupuncture with lift-thrust operation caused a more rapid, stable, and lasting temperature rise of fingertip than that without lift-thrust operation. On the contrary, we observe no significant temperature change when a sham point nearby PC6 (a point which is not traditionally defined as the acupoint) was stimulated. Our results suggest the emulation of manipulation methods such as the lift-thrust operation could be a potential direction for the future development of laser acupuncture.

Acupoint specificity is a foundational concept in acupuncture theory. It is closely related to the function of the acupoint. In this study, we sought to probe the central mechanisms of the specific correlation between LI4 and orofacial part in Bell’s palsy patients. In total, 36 patients with left Bell’s palsy were divided into three groups in random order, and each group received transcutaneous electrical acupoint stimulation (TEAS) at only one of three acupoints (LI4, ST6, and a sham point). A single-block fMRI design paradigm was applied to separately detect neural activity related to different stages of TEAS (prestimulation resting state, stimulation, and poststimulation resting state). Functional magnetic resonance imaging data were acquired during TEAS. There were extensive neuronal activities in the LI4 and ST6 groups and significant differences between stimulation at real and sham points. Brain regions were activated more by real acupoint TEAS than by sham point TEAS. Brain regions that were activated with LI4 and ST6 were broadly overlapping and adjacent. Our results provide supplementary neuroimaging evidence for the existence of acupoint specificity. These results may confirm the central mechanisms of the specific correlation between the Hegu point and the orofacial part.

Clarifying the intrinsic mechanisms of acupuncture’s clinical effects has recently been gaining popularity. Here, we choose the Siguan acupoint (a combination of bilateral LI4 and Liv3) and its sham point to evaluate multiacupoint specificity. Thirty-one healthy volunteers were randomly divided into real acupoint (21 subjects) and sham acupoint (10 subjects) groups. Our study used a single block experimental design to avoid the influence of posteffects. Functional magnetic resonance imaging data were acquired during acupuncture stimulation. Results showed extensive increase in neuronal activities with Siguan acupuncture and significant differences between stimulation at real and sham points. Brain regions that were activated more by real acupuncture stimulation than by sham point acupuncture included somatosensory cortex (the superior parietal lobule and postcentral gyrus), limbic-paralimbic system (the calcarine gyrus, precuneus, cingulate cortex, and parahippocampal gyrus), visual-related cortex (the fusiform and occipital gyri), basal ganglia, and the cerebellum. In this way, our study suggests Siguan may elicit specific activities in human brain.

Acupressure applied on the Extra 1 acupuncture point results in sedation, thereby reducing bispectral index (BIS) values. Mental status and hypnotic agents influence the autonomic nervous system. We hypothesized that acupressure at the Extra 1 point would induce sedation and change sympatho-parasympathetic nerve balance. We investigated the effect of acupressure at the Extra 1 point on the EEG spectral entropy values and heart rate variability (HRV). Forty-eight volunteers (24 males and 24 females) were randomly assigned to the control or Extra 1 group. The control group received acupressure at a sham point and the Extra 1 group received acupressure at the Extra 1 point. Acupressure was applied for 5 min. The record of the EEG spectral entropy values and HRV started 5 min before acupressure and stopped 5 min after acupressure. Acupressure significantly reduced the EEG spectral entropy values in both groups, but the values of the Extra 1 group were significantly smaller than those of the control group (P< .01). Acupressure significantly decreased the LF/HF ratio of HRV in both groups (P< .05). When divided upon gender, although acupressure tended to decrease the LF/HF ratio, the ratio significantly decreased during and after acupressure only in females of the Extra 1 group (P< .05). We concluded that acupressure on the Extra 1 point significantly reduced the EEG spectral entropy in both the genders, but affected the LF/HF ratio of HRV only in females.

Background P6 acupuncture in adults is reported to be an effective preventive treatment for postoperative nausea and vomiting (PONV). It is not clear, however, whether this technique is effective as a preventive treatment for PONV in children. Methods Children undergoing anesthesia and surgery were randomized to four groups: (a) intravenous saline + bilateral P6 acupoint injections (n = 50); (b) intravenous droperidol + bilateral P6 sham acupuncture (n = 49); (c) intravenous saline + bilateral sham point injections (n = 43); (d) intravenous saline +bilateral P6 sham acupuncture (n = 45). The perioperative anesthetic technique was standardized in all subjects. The incidence of postoperative nausea and vomiting (PONV) was evaluated in postanesthesia care unit (PACU) and 24 h after surgery. Results Incidence of nausea in the PACU was significantly lower in the acupoint group as compared with the sham point group (32% vs. 56%, P = 0.029) and P6 sham group (32% vs. 64%, P = 0.002) but not as compared with the droperidol group (32% vs. 46%, P = ns). Similarly, subjects in the acupoint group had a significantly lower incidence of vomiting in the PACU as compared with the sham point group (12% vs. 33%, P = 0.026) and P6 sham group (12% vs. 31%, P = 0.029) but not as compared with the droperidol group (12% vs. 18%, P = ns). The combined incidence of early PONV was also lower in the acupoint group as compared with the sham point group (P = 0.045) and P6 sham group (P = 0.004) but not as compared with the droperidol group (42% vs. 51%, P = ns). Finally, significantly fewer subjects in the acupoint group required intravenous ondansetron as an initial rescue therapy (P = 0.024). At 24 h after surgery, however, the incidence of late PONV was similar among the four study groups (P = ns). Conclusion In children, P6 acupoint injections are as effective as droperidol in controlling early postoperative nausea and vomiting.

The effects of two different traditional acupuncture point combinations and a sham point were compared in 35 healthy volunteers 20 minutes and 2 hours after a single draught of 40% alcohol (1ml/kg body weight). Clinical measurement, using tests of equilibrium and orientation, and specific tests of the metabolism and elimination of alcohol, formed the basis of this comparison. The results are statistically significant (P<0.05). A needle in the sham point produced no measurable effect compared to the non acupuncture control. After both traditional acupuncture point combinations, observing all the measured parameters, the clinical effects of alcohol intoxication were minimised, while the alcohol level in the expired air was increased and the blood alcohol decreased.
