The comprehensive evaluation results show that scalp acupuncture is effective in treating insomnia.

A total of 21 studies were included in this study, and a total of 1606 cases were included. The comprehensive evaluation results show that scalp acupuncture is effective in treating insomnia. Compared with the control group, scalp acupuncture can significantly improve the effective rate of treating insomnia. The PSQI score subgroup analysis showed that the PSQI score of the head was significantly better than that of the drug and blank group, but there was no significant difference from other acupuncture methods. Sensitivity analysis showed that scalp acupuncture ameliorates the PSQI score better, but excluding any item had high heterogeneity. Meta regression analysis of PSQI score according to different intervention measures in the control group showed that the difference of intervention measures in the control group was the source of heterogeneity. In terms of adverse events, the scalp acupuncture group had no adverse events, which was significantly better than the control group. Based on this study, we found that scalp acupuncture is effective and safe in the treatment of insomnia.

Acupuncture treatment of insomnia is efficacious, not because of its placebo effect.

Acupuncture is a common alternative therapy for clinical treatment of insomnia. As the underlying mechanism is yet unclear, its efficacy is often considered as placebo effect. To clarify whether acupuncture treatment of insomnia is only due to its placebo effect, a systematic review and a meta-analysis were designed based on the comparison between acupuncture and sham acupuncture.

Compared to the sham groups, acupuncture significantly decreased the PSQI score (P<0.0001). a subgroup analysis showed that the selection of sham acupuncture methods did not affect results psqi. two trials with total 141 participants major depressive disorder show any significant reductions in psqi scores (p=0.11). addition, difference was detected change insomnia severity index (isi) (362 adult patients, 4 trials) between and (p<0.0001). psg actigraphy data from reveal differences sleep structure changes.

For the selection of sham acupuncture, both methods performed similarly in a clinical setting. Moreover, insomnia patients with major depression disorder were not recommended to use only acupuncture treatment.

Acupuncture may be an effective and safe treatment in obstructive sleep apnea patients.

Besides, acupuncture may also reduce apnea-hypopnea index (AHI) and Epworth Sleepiness Score (ESS) and improve LSaO2 of obstructive sleep apnea patients. This result is more significant in moderate and severe obstructive sleep apnea patients patients. These evidences may be useful to clinicians, patients, and health policy makers with regard to the application of acupuncture in obstructive sleep apnea patients. However, further high-quality RCTs are needed to confirm the efficacy and safety of acupuncture for obstructive sleep apnea patients patients.

Acupuncture therapy is an effective and safe treatment for chronic pain-related insomnia.

In our current study, we pooled the data from nine studies involving 944 patients. Our pooled analysis indicated that acupuncture treatment was significantly better than drugs group in improving effective rate and cure rate and in debasing PSQI score and VAS score. In addition, compared with sham acupuncture, manual acupuncture treatment has an advantage in improving the effective rate and reducing the PSQI score, but the two groups have no statistical significance in improving the cure rate. In this meta-analysis, only four studies reported relevant adverse events. The combined data showed no significant difference in adverse reactions between acupuncture group and control group. Therefore, we can carefully recommend that acupuncture is as safe as control group for CPRI. In addition, adverse events were relatively mild, mainly including bruises, soreness, nausea, dizziness, and other discomforts. These adverse events can be effectively avoided by strengthening the aseptic operation specification, and improving the professional ability of doctors. Based on the findings of our included studies, we propose that acupuncture is an effective and safe therapy for patients with CPRI.

Acupuncture using pattern identification led to significantly improved total effectiveness rate compared to medication for insomnia.

Our main results suggest that both of manual acupuncture and electroacupuncture used with pattern-identification may improve sleep duration, quality of subjective sleep, and daytime function of patients compared with medication. Acupuncture using pattern-identification is one type of individualized therapy and use in actual clinical setting. Our result may provide useful evidence to practitioners in clinical practice because this design may reflect acupuncture treatment in real world.

Acupuncture might have effect in decreasing the number of micturition episodes, incontinence episodes, and nocturia episodes.

Overactive bladder is stated as the occurrence of urinary urgency which will cause negative impacts and decrease patients’ health-related quality of life. The aim of this systematic review is to assess the efficiency and safety of acupuncture for adults with overactive bladder (OAB) comparing with sham-acupuncture, drugs, and acupuncture plus drugs.

Acupuncture might have effect in decreasing the number of micturition episodes, incontinence episodes, and nocturia episodes. However, the evidence is insufficient to show the effect using acupuncture alone or the additional effect to drugs in treating OAB.

Standard acupuncture was significantly more effective for restless legs syndrome severity than control conditions.

The current management of restless leg syndrome is primarily pharmacological, and medications can have unwanted side effects.

Repetitive transcranial magnetic stimulation, exercise, compression devices, counterstrain manipulation, infrared therapy, and standard acupuncture may reduce restless leg syndrome severity.

Vibration pads, cryotherapy, yoga, compression devices, and acupuncture may improve some sleep-related outcomes in restless leg syndrome.

Non-pharmacological interventions for RLS may cause placebo effects and rehabilitation professionals should control for this possibility in future investigations.

The results showed that even fragile populations such as the elderly and dialysis patients can benefit from acupressure to improve sleep quality.

Thirty-two eligible randomized controlled trials of moderate to high quality which employed polysomnography, actigraphy, or self-assessment sleep quality tools were included. We conducted a meta-analysis using a random effects model with the Pittsburgh sleep quality index (PSQI) as the primary outcome measure (968 adult patients, 13 trials) for trials investigating the effects of traditional Chinese medicine acupressure compared with standard and sham treatments.

We performed subgroup analyses to detect sources of heterogeneity, identify the use of acupoints in different populations and explore the contributions of PSQI domains to the total score change. Comparison with the sham group (7 trials with 385 patients) yielded low heterogeneity and an overall effect of 13%–19% improvement in the PSQI score. Based on data from four trials (n = 250), sleep latency and sleep duration were most affected. No adverse effects were reported in any of the reviewed trials.

Acupuncture treatment effectively improved the quality of sleep and the quality of life for chronic hemodialysis patients.

Twenty-eight hemodialysis patients suffering from insomnia were divided randomly into two groups, an acupuncture group (n = 15) who received acupuncture treatment at the points HT7 Shenmen, PC6 Neiguan, GV20 Baihui, and EX-HN1 Sishenchong, anda control group (n = 13) who underwent a sham procedure in which a needle was inserted into an elastic bandage at the same points. The acupuncture treatment was done during hemodialysis twice a week for five weeks. PSQI scores and the WHOQOL-BREF were assessed before treatment, after the fifth treatment, and at the end of the treatment. Significant differences were found in the PSQI score and in the WHOQOL-BREF between the acupuncture group and the control group by the end of the period of treatment. Acupuncture treatment effectively improved the quality of sleep and the quality of life for these chronic hemodialysis patients.

The severity of primary restless legs syndrome symptoms can be significantly ameliorated by acupuncture.

Complementary and alternative therapies have been found to be effective in both primary and secondary restless legs syndrome (RLS). The severity of primary RLS symptoms can be significantly ameliorated by exercise training, transcutaneous spinal direct current stimulation, pneumatic compression devices, light therapy, repetitive transcranial magnetic stimulation, and acupuncture. Pneumatic compression devices and yoga also improve RLS-related disorders. Exercise training is highly efficacious in the reduction of symptom severity in uremic RLS and related effects such as poor quality of life. Endovenous laser ablation may be a good choice for patients with concurrent RLS and superficial venous insufficiency.

Acupuncture is associated with a significant reduction in sleep disturbances in women experiencing menopause-related sleep disturbances.

We identified 31 randomized controlled trials with 34 effect sizes involving a total of 2,433 participants. Acupuncture is associated with a significant reduction in the likelihood of sleep disturbances, a significant increase in the secretion of serum estradiol, and reduction in the secretion of serum follicle-stimulating hormone and luteinizing hormone. Studies with a large effect size of acupuncture-associated changes in serum estradiol had a significantly lower odds of sleep disturbances than did those with a small-to-moderate effect sizes.

Acupuncture is associated with a significant reduction in sleep disturbances in women experiencing menopause-related sleep disturbances. Our findings suggest that acupuncture should be adopted as part of a multimodal approach for improving sleep disturbances in perimenopausal and postmenopausal women.

Both manual acupuncture and electroacupuncture were effective in improving the apnea/hypopnea index and mean SaO2 in the treatment of obstructive sleep apnea.

To the best of our knowledge, this is the first meta-analysis aiming to assess the clinical effect of acupuncture therapy in the treatment of obstructive sleep apnea; six studies involving 362 subjects were selected in our study.

The findings of our work suggest that manual acupuncture was more effective in the improvement of apnea/hypopnea index, apnea index, hypopnea index, and mean SaO2 when compared with nonspecific treatment; electroacupuncture could further improve apnea/hypopnea index and apnea index; there was no significant difference regarding the improvement of hypopnea index and SaO2. Regarding the comparison of manual acupuncture and nasal continuous positive airway pressure (nCPAP) therapy, manual acupuncture was more effective in improving apnea/hypopnea index. No adverse events associated with acupuncture therapy were documented.

Chinese herbal medicine was superior to placebo and benzodiazepine drugs and was superior to benzodiazepines and psychotherapy alone as an adjunct therapy in terms of subjective sleep quality and quantity and safety.

In this study, we systematically reviewed 79 RCTs investigating a variety of Chinese herbal medicine (CHM) treatments for participants with insomnia. We also performed meta-analyses to estimate the efficacy of CHM on subjective sleep quality assessed by validated instruments, patient-rated sleep parameters, clinician-reported severity, and PSG results, as well as to determine the safety of CHM.

Overall, this systematic review and meta-analysis showed that CHM was superior to placebo and benzodiazepine drugs (BZDs) when used as a monotherapy and was superior to BZDs and psychotherapy alone as an adjunct therapy in terms of subjective sleep quality and quantity and safety. CHM was not associated with more benefit than non-BZDs, although the risks were less. These results suggest that CHM could be a promising alternative therapy with a good benefit–risk ratio.

2013 International Review of Neurobiology

The clinical efficacy of acupuncture appeared to be supported by evidence obtained from basic neuroendocrinological studies.

A number of studies have demonstrated that acupuncture may modulate a wide range of neuroendocrinological factors following stimulation of acupoints. Evidence has suggested that the clinical efficacy of acupuncture in treatment of insomnia is potentially mediated by a variety of neurotransmitters including norepinephrine, melatonin, gamma-aminobutyric acid, and β-endorphin. However, due to the complexity, these findings are far from conclusive. More research is necessary. More rigors methodology and integrated approach to evaluate both clinical and basic research evidence are required for future studies.

Clinical studies have shown that acupuncture may have a beneficial effect on insomnia compared with Western medication.

Forty-six (46) randomized trials involving 3811 patients were included, and the methodological quality of trials was generally fair in terms of randomization, blinding, and intention-to-treat analysis. Meta-analyses showed a beneficial effect of acupuncture compared with no treatment and real acupressure compared with sham acupressure on total scores of Pittsburgh Sleep Quality Index. Acupuncture was superior to medications regarding the number of patients with total sleep duration increased for >3 hours. However, there was no difference between acupuncture and medications in average sleep duration. Acupuncture plus medications showed better effect than medications alone on total sleep duration. Similarly, acupuncture plus herbs was significantly better than herbs alone on increase of sleep rates. There were no serious adverse effects with related to acupuncture treatment in the included trials.
