Primary dysmenorrhea is a common gynecological complaint among young women that is related to an autonomic nervous system (ANS) disturbance. Acupuncture is one of several therapeutic approaches for primary dysmenorrhea, since it can modulate ANS function. The heart rate variability (HRV) parameters such as high frequency (HF), low frequency (LF) and LF/HF ratio are generally accepted tools to assess ANS activity. The purpose of this study was to investigate the effects of acupuncture applied at Hegu (LI4) and Sanyinjiao (SP6) points on HRV of women with primary dysmenorrhea during the late luteal phase. The experimental design was a crossover and patient-blinded procedure. All subjects participated in Sham (SA) and Real Acupuncture (RA) procedure, separated by one month, in a crossover sequence. The participants included 38 women (mean age 22.3 years; weight 53.8 kg; height 162.6 cm). HRV measurement was 15 min before and 15 min after an acupuncture procedure. The RA procedure was performed at two bilateral acupoints, but needles were inserted subcutaneously to the acupuncture points for the SA procedure. The RA induced a significant decrease in LF/HF ratio and a significant increase in the HF power, while SA treatment caused a significant increase only in the HF power. Manual acupuncture at bilateral acupoints of LI4 and SP6 may play a role in dysmenorrhea treatment with autonomic nervous system involvement.

Acute gouty arthritis is a common inflammation model with multiple pathogenic mechanisms seen in clinical practice, for which acupuncture may potentially be an alternative therapy. To investigate the effect of acupuncture on acute gouty arthritis and search for its mechanism, a metabonomic method was developed in this investigation. Acute gouty arthritis model rats were induced by monosodium urate (MSU) crystals. The urine and plasma samples were collected at several time points and the endogenous metabolites were analyzed by an ultra-performance liquid chromatography coupled with a mass spectrometry (UPLC-MS). Data were analyzed using principal components analysis (PCA) and partial least squares (PLS) analysis to compare metabolic profiles of MSU crystal-induced acute gouty arthritis rats with MSU crystal-induced acute gouty arthritis, treated with acupuncture rats. The results showed that acupuncture could restore the metabolite network that disturbed by MSU administration. Our study indicates that UPLC-MS-based metabonomics can be used as a potential tool for the investigation of biological effect of acupuncture on acute gouty arthritis.

Acupuncture is often recommended for obstetrical and gynecological conditions but the evidence is confusing. We aim to summarize all recent systematic reviews in this area. Western and Asian electronic databases were searched for systematic reviews of any type of acupuncture for any type of gynecological conditions. Our own files were hand-searched. Systematic reviews of any type of acupuncture for any type of gynecological conditions were included. Non-systematic reviews and systematic reviews published before 2004 were excluded. No language restrictions were applied. Data were extracted according to predefined criteria and analysed narratively. Twenty-four systematic reviews were included. They relate to a wide range of gynecological conditions: hot flashes, conception, dysmenorrhea, premenstrual syndrome, nausea/vomiting, breech presentation, back pain during pregnancy, and procedural pain. Nine systematic reviews arrived with clearly positive conclusions; however, there were many contradictions and caveats. The evidence for acupuncture as a treatment of obstetrical and gynecological conditions remains limited.

This paper presents the evident effects of acupoint stimulation, using EEG (electroencephalogram) measurements. With acupuncture stimulation and the EEG measurement on the same meridian, EEG is able to accurately detect the effects of acupunctural point stimulation on brain waves.

In this study, 24 subjects without heart or neural diseases were randomly separated into two groups of 12, named test and control groups. Similar procedures are performed; the subjects lay on a bed with eyes closed for ten minutes as the baseline. The test group received acupuncture at their Waiguan points (TE5) on their left hands for 20 minutes, while the control group did not. EEGs are recorded during pre-acupuncture, acupuncture stimulation and post-acupuncture stimulation periods. The EEG electrodes are at the T3, T4, O1 and O2 locations. Continuous wavelet transformation analysis is adopted; therefore, EEGs are divided into the following bands: δ (0.5–4HZ), θ (4–8HZ), α (8–13HZ) and β (13–30HZ).

During acupuncture stimulation, the θ energy is increased and had statistical differences at all electrode points, T3, T4, O1 and O2. Upon removing the needle, the energy at the T3 and T4 points slowly declined and revealed obvious statistical differences. During acupuncture, only α energy has been noted to have statistical difference and it was increased at the T3 point. However, the energy was decreased and had no statistical difference after five minutes.

Acupuncture is proven to be able to affect brain waves, as the stimulation might have changed the tissues between the cranium and scalp; therefore, the brain waves are detected more easily.

This research explored and identified the protein composition of rat kidneys after acupuncture at the Taixi acupoint (KI3). Twelve adult male Wistar rats were randomly divided into a control group (n = 6) and an acupuncture group (n = 6). Rats in the acupuncture group received electroacupuncture on the bilateral KI3 for seven days. The kidneys were perfused with ice-cold saline and all kidney proteins were isolated. After protein sample preparation, two-dimensional gel electrophoresis (2-DE) was performed. The interesting spots were analyzed using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). There were nine protein spots with three-fold up-regulation in the kidney after the acupuncture. NAD-dependent isocitrate dehydrogenase and quinone reductase, the proteins involved in energy metabolism, the reduction of endogenous quinones, chemoprotection, and electrophilic stress, were identified. The data indicated that acupuncture at the KI3 of the kidney meridian of the foot shaoyin was able to increase NAD-dependent isocitrate dehydrogenase and quinone reductase expression in the kidney, and supported the relationship between the kidney and KI3.

Noncyclic breast pain is a common breast disorder prompting women to seek medical evaluation. We aimed to perform a pilot study on the relief of noncyclic breast pain using acupuncture. Thirty-seven women seen at a diagnostic breast clinic between April 2003 and January 2009 were enrolled. Treatment consisted of four acupuncture sessions over two weeks, with three months of follow-up. Response to treatment was measured with use of a breast pain questionnaire, a quality of life (QOL) questionnaire, and the Cleeland Brief Pain Inventory (BPI) assessed at baseline, end of treatment, and three months after treatment. Data were analyzed using standard descriptive statistics. Twenty-two patients completed four acupuncture sessions. Pain described as throbbing and heavy decreased significantly after acupuncture (p = 0.04 and p = 0.03, respectively). After treatment, pain scores (on the 10-point BPI scale) decreased by an average of 3.5 points for the worst pain during the previous month (p = 0.001), by 2.7 points for average pain (p < 0.001), and by 2.3 points for pain interference (p = 0.002). The percentage of patients reporting a clinically meaningful decrease of 2 points from baseline to the end of treatment included 67% (12/18) for the worst pain, 65% (11/17) for average pain, and 56% (10/18) for pain interference. QOL data showed no improvement in QOL measures (mental, physical, emotional, social, or spiritual well-being). The results of this preliminary study suggest that a randomized controlled trial may be warranted to evaluate the effect of acupuncture on noncyclic breast pain, as well as the optimal frequency of acupuncture treatments.

Acupuncture has many beneficial effects during cancer therapy and has proven efficacy in the management of side effects induced by chemotherapy and radiotherapy. In this review, we discussed the benefits of acupuncture on cancer patients. In cancer pain management, acupuncture is effective for head and neck pain, waist pain, abdominal and chest pain. Many studies confirm the excellent efficacy of acupuncture against symptoms of vomiting and nausea, including those induced by chemotherapy and radiotherapy. Head and neck cancer patients receiving radiotherapy may develop xerostomia, which may be relieved by acupuncture. Acupuncture may also cause sedative and hypnotic effects in cancer patients for treating nervousness and insomnia.

Smoking represents a serious worldwide public health problem because of its close association with the development of chronic disease and cancer. Acupoint stimulation has been used as treatment mode for smoking cessation but its efficacy remains controversial. This systematic review and meta-analysis aimed to determine the effects of acupoint stimulation on smoking cessation rate and daily cigarette consumption. Electronic literature searches in eight electronic databases up to March 2011 were performed to identify acupoint stimulation for smoking cessation. The outcomes assessed were smoking cessation rate and cigarette consumption. We assessed abstinence from smoking at the earliest and last measured time points, and at the 3- and 6-month follow-ups. Meta-analysis was performed using CMA software. A total of 20 RCTs were included in the meta-analysis. A significant effect of acupoint stimulation was found in smoking cessation rates and cigarette consumption at immediate, 3- and 6-month follow-ups, with effect sizes 1.24 (95%CI = 1.07 ~ 1.43, p = 0.003), -2.49 (95%CI = -4.65 ~ -0.34, p = 0.02), 1.70 (95%CI = 1.17 ~ 2.46, p = 0.01), and 1.79 (95%CI = 1.13 ~ 2.82, p = 0.01), respectively. Multi-modality treatments, especially acupuncture combined with smoking cessation education or other interventions, can help smokers to eschew smoking during treatment, and to avoid relapse after treatment.

This study is to investigate the influences of acupuncture for dyspepsia on the Radial Pressure Pulse (RPP) between the Chun, Guan and Chy positions of the right/left wrist. Two series of experiments were designed; for the first series, 30 patients with dyspepsia (Group P) and 30 normal subjects (Group N) were seated to undergo the measurements of pulse pressure waveforms from radial artery by sphygmograph. The parameters of RPP included the spectral energy of 0–10 Hz (SE_0–10Hz), 10–50 Hz (SE_10–50Hz) and 13–50 Hz (SE_13–50Hz). For the second series, acupuncture was administered at the right and left Tsu San Li (St-36) points for the same 30 dyspepsia patients, and then their pulse pressure waveforms were re-examined. The results showed that the SE_0–10Hz at Right Guan (RB) (p < 0.05), the SE_10–50Hz at RB (p < 0.01), and the SE_13–50Hz at RB (p < 0.01) and Left Guan (LB) (p < 0.05) of Group P were significantly greater than that of Group N. After the acupuncture, there were significant decreases in the SE_0–10Hz only at RB (p < 0.01), in the SE_10–50Hz at RB (p < 0.01), Right Chy (RC) (p < 0.05) and LB (p < 0.05), and in the SE_13–50Hz RB (p < 0.01), RC (p < 0.05) and LB (p < 0.01). We concluded that the pulse-frequency spectrum at RB was a more effective characteristic for dyspepsia patients, and the acupuncture had an effect on SE_10–50Hz and SE_13–50Hz more obviously than that on SE_0–10Hz.

Stroke is one of the most common causes of death and few pharmacological therapies show benefits in ischemic stroke. In this study, 290 patients aged 40–75 years old with first onset of acute ischemic stroke (more than 24 hours but within 14 days) were treated with standard treatments, and then were randomly allocated into an intervention group (treated with resuscitating acupuncture) and a control group (treated using sham-acupoints). Primary outcome measures included Barthel Index (BI), relapse and death up to six months. For the 290 patients in both groups, one case in the intervention group died, and two cases in the control group died from the disease (p = 0.558). Six patients of the 144 cases in the intervention group had relapse, whereas 34 of 143 patients had relapse in the control group (p < 0.001). The mean values for BI at six months were 70.25 ± 20.37 and 57.43 ± 19.61 for the two groups, respectively (p < 0.01). Acupuncture resulted in a significant difference between the two groups for the National Institute of Health Stroke Scale (NIHSS), not at two weeks (7.03 ± 3.201 vs. 8.13 ± 3.634; p = 0.067), but at four weeks (4.15 ± 2.032 vs. 6.35 ± 3.131, p < 0.01). The Chinese Stroke Scale (CSS) at four weeks showed more improvement in the intervention group than that in the control group (9.40 ± 4.51 vs. 13.09 ± 5.80, p < 0.001). Stroke Specific Quality of Life Scale (SS-QOL) at six months was higher in the intervention group (166.63 ± 45.70) than the control group (143.60 ± 50.24; p < 0.01). The results of this clinical trial showed a clinically relevant decrease of relapse in patients treated with resuscitating acupuncture intervention by the end of six months, compared with needling at the sham-acupoints. The resuscitating acupuncture intervention could also improve self-care ability and quality of life, evaluated with BI, NIHSS, CSS, Oxford Handicap Scale (OHS), and SS-QOL.

Previous work from our team and others has shown that manual acupuncture at LI4 (hegu), ST36 (zusanli), and LV3 (taichong) deactivates a limbic-paralimbic-neocortical brain network, and at the same time activates somatosensory regions of the brain. The objective of the present study was to explore the specificity and commonality of the brain response to manual acupuncture at LI4, ST36, and LV3, acupoints that are located on different meridians and are used to treat pain disorders. We used functional magnetic resonance imaging (fMRI) to monitor the brain responses to acupuncture at three different acupoints; we examined 46 healthy subjects who, according to their psychophysical responses, experienced deqi sensation during acupuncture. Brain responses to stimulation at each of the acupoints were displayed in conjunction with one another to show the spatial distribution. We found clusters of deactivation in the medial prefrontal, medial parietal and medial temporal lobes showing significant convergence of two or all three of the acupoints. The largest regions showing common responses to all three acupoints were the right subgenual BA25, right subgenual cingulate, right isthmus of the cingulum bundle, and right BA31. We also noted differences in major sections of the medial prefrontal and medial temporal lobes, with LI4 predominating in the pregenual cingulate and hippocampal formation, ST36 predominating in the subgenual cingulate, and LV3 predominating in the posterior hippocampus and posterior cingulate. The results suggest that although these acupoints are commonly used for anti-pain and modulatory effects, they may mobilize the same intrinsic global networks, with substantial overlap of common brain regions to mediate their actions. Our findings showing preferential response of certain limbic-paralimbic structures suggests acupoints may also exhibit relative specificity.

This study was designed to compare the weight reduction effects of acupuncture for obese women with or without perimenopausal syndrome. We observed 60 women with either simple obesity or perimenopausal obesity (obesity complicated with perimenopausal syndrome) treated by five acupuncture treatments given in the first week of three successive four-week treatment courses, and obesity indexes including body weight, body mass index, obesity degree and waist/hip ratio were evaluated. Versus baseline, the obesity indexes decreased at the end of each treatment course in women with simple obesity (p < 0.05 or p < 0.01), while women with perimenopausal obesity showed no decrease at the end of the first course of treatment, and these indexes decreased at the end of the second and the third courses of treatment (p < 0.05). There was no difference when comparing obesity indexes recorded at the end of three courses of treatment and at the end of three-month follow-up between women with simple obesity and those with perimenopausal obesity. The results suggest that acupuncture reduced body weight in the obese women, and the weight loss occurred earlier in the treatment process for simple obesity than perimenopausal obesity.

Chronic low back pain is one of the most common reasons that people seek medical treatment, and the consequent disability creates a great financial burden on individuals and society. The etiology of chronic low back pain is not clear, which means it is often refractory to treatment. Acupuncture has been reported to be effective in providing symptomatic relief of chronic low back pain. However, it is not known whether the effects of acupuncture are due to the needling itself or nonspecific effects arising from the manipulation. To determine the effectiveness of acupuncture therapy, a meta-analysis was performed to compare acupuncture with sham acupuncture and other treatments. Overall, 2678 patients were identified from thirteen randomized controlled trials. The meta-analysis was performed by a random model (Cohen's test), using the I-square test for heterogeneity and Begg's test to assess for publication bias. Clinical outcomes were evaluated by pain intensity, disability, spinal flexion, and quality of life. Compared with no treatment, acupuncture achieved better outcomes in terms of pain relief, disability recovery and better quality of life, but these effects were not observed when compared to sham acupuncture. Acupuncture achieved better outcomes when compared with other treatments. No publication bias was detected. Acupuncture is an effective treatment for chronic low back pain, but this effect is likely to be produced by the nonspecific effects of manipulation.

This study was to evaluate the efficacy and safety of acupuncture for chronic functional constipation. Randomized controlled trials were searched in several databases. The primary outcome was a change in the number of weekly spontaneous bowel movements. The secondary outcomes included colonic transit activity, effective rate, Cleveland Clinic Score, and health-related quality of life score. Meta-analysis was done by using RevMan 5.1. After strict screening, 15 RCTs were included, containing 1256 participants. All of them were conducted in China and published in Chinese journals. Meta-analysis indicated that acupuncture for chronic functional constipation was probably as effective as conventional medical therapy in the change of bowel movements. For the colonic transit activity, acupuncture might be the same as conventional medical therapy and could be better than sham acupuncture. For the Cleveland Clinic Score, acupuncture was unlikely inferior to conventional medical therapy and the deep acupuncture was better than normal depth acupuncture in abdominal region. No obvious adverse event was associated with acupuncture for constipation. In conclusion, acupuncture for chronic functional constipation is safe and may improve weekly spontaneous bowel movements, quality of life, and relevant symptoms. However, the evidence was limited by the small sample size and the methodological quality.

This study aimed to determine the efficacy of Integrated Rehabilitation Techniques of Traditional Chinese Medicine (IRT-TCM) on patients with ischemic stroke as an alternative therapy to conventional rehabilitation techniques. Sixty-nine patients with ischemic stroke were randomly assigned to receive either IRT-TCM (intervention group, n = 46) or conventional rehabilitation techniques (control group, n = 23). The IRT-TCM consisted of a sequential combination of acupuncture and massage techniques. The Fugl-Meyer Assessment (FMA), National Institutes of Health Stroke Scale (NIHSS), Barthel index (BI) and modified Rankin Scale (mRS) were measured on day 0 (baseline, before treatment), day 21, and day 90. We observed that the scores in FMA and BI were increased, and NIHSS were decreased in both groups on day 21 and 90, compared with the baseline (day 0). Furthermore, significantly better scores in FMA of lower limbs and NIHSS were found in patients treated with IRT-TCM on day 21 and 90. For mRS, the percentage of patients ranking 0 and 1 in the intervention group presented a striking contrast to the control group on day 90 but with no significant difference. The results indicated that, as a feasible alternative therapy, IRT-TCM is beneficial for patients with ischemic stroke. Further research with larger sample size, long-term observation, and strict blinding are still in need to confirm the efficacy of IRT-TCM.

Characteristics of female and male visitors to practitioners of acupuncture were investigated in a large cross-sectional adult population in Central Norway. A total population health survey, HUNT3, conducted in 2008 with 50,827 respondents provided the data. Demographic variables, lifestyle, health, and use of conventional medicine were analyzed using multivariable logistic regression models. The one year prevalence of visiting a practitioner of acupuncture was 5.7% for females and 2.2% for males. Visitors of both genders were five times more likely to have had somatic complaints in the preceding year and were 2–3 times more likely to report poor global health than female or male non-visitors. Also, visitors of both genders were more likely to do hard physical activities every week, and they were less likely to live alone or be daily smokers. Further, female visitors were characterized by having higher education and were more likely to have a paid job than other females. Corresponding differences were not seen among males. Age showed limited associations with being a visitor, and for females only. Valid for both genders, our findings draw a picture of visitors to acupuncture treatment as persons who actively contribute to promoting their health through lifestyle choices of physical activity and non-smoking while simultaneously having worse global health and higher burdens of somatic complaints than other adults. In contrast to males, it is suggested that females may be more dependent on personal income, as indicated by higher education and being in a paid job, in choosing acupuncture treatment in addition to conventional medicine.

The clinical practice of acupuncture and study of the traditional Chinese medicine literature has led to the observation that if the diaphragm is used as an axis of symmetry, there are many symmetrical points on the upper and lower halves of the body. The symmetrical points share several common properties, including physiological functions, mechanisms of pathogenesis and therapeutic effects. Employing these corresponding points on the upper and lower parts of the body simultaneously can frequently enhance the therapeutic outcome rather substantially. This phenomenon may be called the Principle of Symmetry. Traditional and modern scientific literature already provides evidence that verifies the reliability of this principle. Furthermore, this principle may be viewed as the derivative of the Thalamic Neuron Theory.

This study was designed to evaluate the analgesic effect of wrist-ankle acupuncture (WAA) for patients with primary liver cancer (PLC) after transcatheter arterial chemoembolization (TACE). Sixty PLC patients with post-TACE visual analog pain intensity scores greater than 3 were divided equally into two groups receiving either WAA or oral morphine sulphate (MOR) for post-TACE pain. Pain intensity scores were reassessed at 1, 2, 4, and 6 h after analgesic intervention. Patients were also monitored for adverse reactions to analgesic treatment. Pain scores recorded when the patients first felt pain after TACE showed no statistical difference between the two groups (p > 0.05). WAA and MOR had indistinguishable degrees of pain relief 1, 2, and 4 h after analgesic intervention (p > 0.05). At 6 h after intervention, the WAA group experienced significantly greater pain relief than the MOR group (p < 0.05). Incidence of abdominal distension was lower in the WAA group than in the MOR group (p < 0.05). The results suggest that WAA not only had an analgesic effect equal to or greater than MOR in PLC patients with moderate to severe post-TACE pain, but also reduced the incidence of post-operative abdominal distention.

Acupuncture and electroacupuncture treatments of symptomatic carpal tunnel syndrome (CTS) may improve symptoms and aid nerve repair as well as improve sensory and motor functions. However, limited evidence is available regarding the effects of these treatments based on comprehensive evaluation methods. This research completed the treatment and evaluation of 26 patients with confirmed CTS. Participants were divided into two treatment groups based on a modified neurophysiological grading scale. Of the total number of participants, 15 received acupuncture and 11 received electroacupuncture on both upper limbs. Acupoints were PC-7 (Daling) and PC-6 (Neiguan) along the pericardial meridian compatible with the median nerve tract. The treatment program consisted of 24 sessions of 15 min duration over 6 weeks. After electroacupuncture treatments, symptom severity was evaluated using the short clinical questionnaire by Lo and Chiang, which indicated improvements in the respective symptom severity score. After the acupuncture treatment, grip strength in the major symptomatic side in CTS patients could be significantly increased. Electrophysiology evaluation likewise indicated a significant increase in the distal median motor amplitude of the palm-wrist segment. In addition, Tinel's sign significantly decreased in the major symptomatic side. Our findings indicated that electroacupuncture could improve symptomatology, while acupuncture could exert positive therapeutic effects for CTS patients, as evidenced by improved symptomatology, grip strength, electrophysiological function, and physical provocation sign.

Scant scientific evidence supports the efficacy of acupuncture in the treatment of opiate dependence. The purpose of this study was to examine the effectiveness of acupuncture for heroin addicts on methadone maintenance by measuring the daily consumption of methadone, variations in the 36-item Short Form Health Survey-36 (SF-36) and Pittsburgh Sleep Quality Index (PSQI) scores, and heroin craving. Sixty heroin addicts were randomly assigned to true acupuncture (electroacupuncture at the Hegu [LI4] and Zusanli [ST36] acupoints, as well as acupuncture at the Ear Shenmen) or sham acupuncture (minimal acupuncture at the Hegu and Zusanli acupoints without electrical stimulation and superficial acupuncture at the Ear Shenmen), twice weekly for 4 weeks. From week 2 onwards, the daily dose of methadone was reduced by a significantly greater amount with true acupuncture compared with sham acupuncture. True acupuncture was also associated with a greater improvement in sleep latency at follow-up. All adverse events were mild in severity. Acupuncture appears to be a useful adjunct to methadone maintenance therapy (MMT) in heroin addiction.
