Intradermal acupuncture in the treatment of rheumatoid arthritis with liver and kidney deficiency syndrome - A sham-controlled, randomized, clinical trial

BACKGROUND AND PURPOSE

Rheumatoid arthritis (RA) is called "immortal cancer", and it affects the quality of life, disability rate and even the survival of patients. This study aimed to observe the clinical efficacy, and adverse reactions of intradermal acupuncture (IA) in the treatment of RA patients with liver and kidney deficiency syndrome.

MATERIALS AND METHODS

132 RA patients were split into an IA group and a sham IA group at a 1:1 ratio. Both groups were assessed before and after the intervention with the assessments: a traditional Chinese medicine (TCM) syndrome evaluation, the Health Assessment Questionnaire (HAQ), the Disease Activity Score 28 (DAS28) and serum C-reactive protein (CRP).

RESULTS

There was a statistically significant difference in TCM syndrome evaluation, HAQ, DAS28, and CRP between both groups before and after treatment (P < 0.01). The improvement of TCM syndrome evaluation (95% CI [1.14(0.38-1.89)]; P = 0.001), HAQ (95% CI [2.00(1.00-3.00)]; P = 0.003), and DAS28 (95% CI [0.11(0.02-0.20)]; P = 0.021) in the IA group was more obvious than that in the sham IA group (P < 0.05), except for CRP (95% CI [0.50(- 2.09 to 7.08)], P = 0.786). The difference in CRP outcome changes between the two groups was not statistically significant (P > 0.05). Both groups had comparable results in the implementation of RA in the upper and lower extremity acupoints and did not differ due to different sites (IA group: P = 0.852; sham IA group: P = 0.861). The comparison of effective rate of the upper limb as well as that of the lower limb was statistically significant (P = 0.001). Besides, patients reported no adverse effects.

CONCLUSION

The IA intervention was associated with a promising effect on the decrease in RA disease activity and delayed overall disease progression.

Effectiveness of electroacupuncture on anxiety: a systematic review and meta-analysis of randomized controlled trials

This systematic review and meta-analysis aimed to comprehensively evaluate the effectiveness of electroacupuncture (EA) for patients with anxiety. Randomized controlled trials (RCTs) on the treatment of anxiety by EA up to November 2022 were searched and collected from nine databases. Hamilton Anxiety Rating Scale (HAMA), self-rating anxiety scale (SAS), and adverse reactions were used as outcome indicators. The quality of relevant articles was evaluated using the Cochrane Collaboration's risk of bias tool. The quality of evidence for each outcome was classified as "low risk," "unclear risk," or "high risk." RevMan 5.0 was used for data analysis. A total of 633 articles were identified from nine electronic databases; 37 RCTs were included, which measured anxiety changes by using EA alone compared to the control group. For the main outcome, EA significantly reduced the HAMA score [Mean difference (MD):-1.13 (95% CI:-2.55-0.29), I2:80%], and the quality of evidence was moderate. EA significantly reduced the SAS score (MD:-3.47 (95% CI,-6.57--0.36), I2:88%), and the quality of evidence was moderate. Our meta-analysis shows that EA reduces HAMA and SAS. This study suggests that EA can relieve anxiety. For various uses, additional research is needed on its effect when combined with other treatments.

Electroacupuncture attenuates myocardial ischemia-reperfusion injury by inhibiting microglial engulfment of dendritic spines

A major side effect of reperfusion therapy following myocardial infarction is myocardial ischemia-reperfusion injury (MIRI). Electroacupuncture preconditioning (EA-pre) has a long history in the treatment of cardiovascular diseases. Here, we demonstrate how EA-pre attenuates MIRI by affecting the phagocytosis of neuronal dendritic spines of microglia of the fastigial nucleus (FNmicroglia). We observed that EA-pre increased activity in FNGABA and then improved myocardial injury by inhibiting abnormal activities of glutaminergic neurons of the FN (FNGlu) during MIRI. Interestingly, we observed changes in the quantity and shape of FN microglia in mice treated with EA-pre and a decrease in the phagocytosis of FNGABA neuronal dendritic spines by microglia. Furthermore, the effects of improving MIRI were reversed when EA-pre mice were chemically activated by intra-FN lipopolysaccharide injection. Overall, our results provide new insight indicating that EA-pre regulates microglial engulfment capacity, thus promoting the improvement of cardiac sympathetic nervous disorder during MIRI.

The efficacy and cerebral mechanism of intradermal acupuncture for major depressive disorder: a study protocol for a randomized controlled trial

Background

Major depressive disorder (MDD) has emerged as the fifth leading cause of years lived with disability, with a high prevalent, affecting nearly 4% of the global population. While available evidence suggests that intradermal acupuncture may enhance the effectiveness of antidepressants, whether its efficacy is a specific therapeutic effect or a placebo effect has not been reported. Moreover, the cerebral mechanism of intradermal acupuncture as a superficial acupuncture (usually subcutaneous needling to a depth of 1-2 mm) for MDD remains unclear.

Methods

A total of 120 participants with MDD will be enrolled and randomized to the waiting list group, sham intradermal acupuncture group and active intradermal acupuncture group. All 3 groups will receive a 6-week intervention and a 4-week follow-up. The primary outcome will be measured by the Hamilton Depression Rating Scale-17 and the secondary outcome measures will be the Self-Rating depression scale and Pittsburgh sleep quality index. Assessments will be conducted at baseline, 3 weeks, 6 weeks, and during the follow-up period. In addition, 20 eligible participants in each group will be randomly selected to undergo head magnetic resonance imaging before and after the intervention to explore the effects of intradermal acupuncture on brain activity in MDD patients.

Discussion

If the intradermal acupuncture is beneficial, it is promising to be included in the routine treatment of MDD.

Acupuncture increases parasympathetic tone, modulating HRV - Systematic review and meta-analysis

INTRODUCTION

An increasing number of studies have demonstrated that acupuncture can influence Autonomic Nervous System functions. Heart Rate variability (HRV) is one widely used marker of autonomic activity. The main objective of this systematic review is to critically assess the evidence from randomized clinical trials (RCTs) regarding the effect of acupuncture on HRV as compared to placebo methods.

METHOD

EMBASE, Pubmed, The Cochrane Library, Web of Science, Scopus electronic databases were searched until 9 September 2020 for RCTs in which human subjects were treated with needle acupuncture using acupoints of the body without electric stimulation.

RESULTS

The searches identified 1698 potentially relevant articles, 9 RCTs were included. The statistical analysis of the available data showed that the changes between pre and post treatment HF (high frequency) and LF/HF (high frequency/low frequency) values in Verum group were significant, while there were no significant changes in these parameters in Sham groups.

CONCLUSION

the results of this meta-analysis suggest that real acupuncture has superior effect over placebo acupuncture in increasing parasympathetic tone and in this way may improve physical well-being. Due to the quality of primary studies and degree of heterogeneity the results should be interpreted cautiously.

The Therapeutic Effects of Acupuncture and Electroacupuncture on Cancer-related Symptoms and Side-Effects

In addition to cancer-related death, malignant progression also leads to a series of symptoms and side-effects, which would detrimentally affect cancer patients' the quality of life, adversely influence their adherence to treatments, and, therefore, negatively affect their long-term survival. Acupuncture and electroacupuncture (EA), as two classic treatment methods in traditional Chinese medicine, have been widely employed to cure various diseases. Recently, the clinical application of acupuncture and EA in cancer patients has received great attention. In this review, we summarized the clinical application of acupuncture and EA in alleviating the cancer symptoms, reducing the cancer treatment-related side-effects, and relieving the cancer pain. The symptoms and side-effects discussed in this review include fatigue, insomnia, chemotherapy-associated dyspepsia syndrome (CADS), pain, xerostomia, and anxiety and depression. The underlying mechanisms of the therapeutic effects of acupuncture and EA might be related to the regulation of the mitochondrial function, coordination of the activity of the nervous system, adjustment of the production of neurotransmitters, and alleviation of the immune responses. In conclusion, acupuncture and EA have been proved to be beneficial for cancer patients. More research, however, is required to clarify the potential mechanisms behind acupuncture and EA for widespread adoption in clinical application.

The efficacy of integrated cognitive behavioral therapy (CBT) and acupressure versus CBT for insomnia: a three-arm pilot randomized controlled trial

OBJECTIVES

This pilot study aimed to examine the efficacy of integrated cognitive behavioral therapy (CBT) and acupressure in treating insomnia and its daytime impairments in a Chinese adult population.

METHODS

40 eligible participants with insomnia were randomly assigned to either the integrated CBT and acupressure (CBTAcup) group (n = 14), the CBT group (n = 13), or the waitlist control (WL) group (n = 13). Participants in the CBTAcup group attended a 2-hour integrated CBT and self-administered acupressure group treatment once per week for six consecutive weeks, while participants in the CBT group attended six weekly 2-hour CBT for insomnia. Sleep, mood, daytime impairments, quality of life, and treatment credibility and adherence were assessed at baseline, immediate post-treatment (Week 7), and 4-week post-treatment (Week 11).

RESULTS

Linear mixed-effects models showed that both the CBTAcup and CBT groups had significantly lower insomnia severity (d = -1.74 and d = -2.61), dysfunctional beliefs related to sleep (d = -2.17 and -2.76), and mental fatigue (d = -1.43 and -1.60) compared with the WL group at Week 7. The CBTAcup group provided additional benefits in reducing total fatigue (d = -1.43) and physical fatigue (d = -1.45). Treatment credibility was found to be improved in the CBTAcup group from baseline to Week 7.

CONCLUSIONS

Integrated CBT and acupressure demonstrated comparable efficacy to pure CBT in treating insomnia symptoms, with additional advantages to improve fatigue symptoms and acceptability in the Chinese population. Further methodologically rigorous studies on a larger scale and longer follow-up are warranted to confirm these findings.

Acupuncture Reduced the Risk for Insomnia in Stroke Patients: A Propensity-Score Matched Cohort Study

Background: Post-stroke insomnia (PSI) affects the quality of life for stroke patients, reduces the likelihood of successful rehabilitation, and produces additional complications following stroke. Previous reports have provided some information regarding PSI risk factors, but little is known concerning protective factors for PSI. This study analyzed the relationship between acupuncture and insomnia in stroke patients and explored the use of acupuncture as a preventive treatment.

Methods: Patients diagnosed with stroke from 2010 to 2019 were identified in the case database of the First Affiliated Hospital of Guangzhou University of Chinese These patients followed until 2020, and numerous factors were examined, including gender, age, stroke type, stroke location, and baseline comorbidities. A 1:1 propensity score was used to match an equal number of patients receiving acupuncture with stroke patients who did not receive acupuncture (N = 1,680 for each group). The purpose of the study was to compare the incidence of insomnia in these two stroke cohorts. We used the Cox regression model and Kaplan-Meier method to estimate the risk of insomnia as the outcome event.

Results: Compared with the non-acupuncture cohort in general, stroke patients who received acupuncture treatment exhibited a lower risk of insomnia after adjusting for age, gender, stroke type, stroke location, and comorbidities (adjusted hazard ratio HR = 0.27, 95% confidential interval = 0.23 to 0.32). Acupuncture also reduced the risk of PSI for both genders. The respective risks were HR = 0.28 (adjusted) for males and HR = 0.26 (adjusted) for females. Acupuncture also lowered the risk for PSI for different age groups. The risks were HR = 0.22 (adjusted) for individuals 18 to 39 years of age, HR = 0.31 (adjusted) for individuals 40 to 59 years of age, HR = 0.28 (adjusted) for those 60 to 79 years of age, and HR = 0.18 (adjusted) for individuals 80 years of age and older. Concerning the stroke type, regardless of whether the stroke was ischemic, hemorrhagic, or a combination of the two stroke types, patients who received acupuncture exhibited lower risk (adjusted HR = 0.28, 0.17, and 0.49, respectively). Concerning stroke location, except for the cerebral hemispheres (adjusted HR = 1.10, 95% confidential interval = 0.12 to 1.01), the risk of PSI after receiving acupuncture was lower for the frontal lobe (adjusted HR = 0.42), the basal ganglia (adjusted HR = 0.22), the radiation crown (adjusted HR = 0.42), the diencephalon (adjusted HR = 0.20), or multiple partial strokes (adjusted HR = 0.26), the risk of PSI after receiving acupuncture was lower. For all baseline complications, acupuncture reduced the risk of insomnia. The cumulative incidence of insomnia in the acupuncture cohort was significantly lower than the non-acupuncture cohort (log-rank test, P = 0.000).

Limitations: First, our research only included patients from a single center. Second, we did not classify the post-stroke insomnia severity. Second, the information was extracted manually. Overall, the sample size was small, and we needed to increase the sample size to strengthen the conclusions.

Conclusion: Acupuncture treatment reduced the risk of insomnia in stroke patients. Future research be conducted with increased sample sizes and further elaboration on the specific acupuncture protocols that were used.

Efficacy and safety of electroacupuncture combined with Suanzaoren decoction for insomnia following stroke: study protocol for a randomized controlled trial

BACKGROUND

Insomnia is a common but frequently overlooked sleep disorder after stroke, and there are limited effective therapies for insomnia following stroke. Traditional Chinese medicine (TCM), including acupuncture and the Chinese herbal medication (CHM) Suanzaoren decoction (SZRD), has been reported as an alternative option for insomnia relief after stroke in China for thousands of years. Here, this study aims to investigate the efficacy and safety of electroacupuncture (EA) in combination with SZRD in the treatment of insomnia following stroke.

METHODS

A total of 240 patients with post-stroke insomnia will be included and randomized into four groups: the EA group, SZRD group, EA & SZRD group, and sham group. The same acupoints (GV20, GV24, HT7, and SP6) will be used in the EA group, EA & SZRD group, and sham group, and these patients will receive the EA treatment or sham manipulation every other day for 4 consecutive weeks. SZRD treatments will be given to participants in the SZRD group and EA & SZRD group twice a day for 4 consecutive weeks. The primary outcome measures include Pittsburgh Sleep Quality Index scores and polysomnography. Secondary outcome measures include the Insomnia Severity Index, the National Institutes of Health Stroke Scale, the Hospital Anxiety and Depression Scale, brain magnetic resonance imaging, functional magnetic resonance imaging, and nocturnal melatonin concentrations. The primary and secondary outcomes will be assessed at baseline (before treatment), during the 2nd and 4th weeks of the intervention, and at the 8th and 12th weeks of follow-up. Safety assessments will be evaluated at baseline and during the 4th week of the intervention.

DISCUSSION

This study will contribute to assessing whether the combination of these two therapies is more beneficial for post-stroke insomnia than their independent use, and the results of this clinical trial will improve our understanding of the possible mechanisms underlying the effects of combination therapies.

Intradermal acupuncture for rheumatoid arthritis: study protocol for a randomised controlled trial

Background

Rheumatoid arthritis (RA) is a common autoimmune disease that severely impacts quality of life. Currently available medications for the treatment of RA have adverse side effects. Emerging evidence suggests that intradermal acupuncture (IA) is feasible and safe for patients, but its application in RA patients has not been examined. Our study aims to explore the efficacy and safety of IA for the treatment of RA.

Methods

This study is a randomised, sham-controlled, patient-outcome assessor-statistician blind trial that aims to evaluate the effects of IA in patients with RA. We will recruit 132 patients aged ≥ 18 years with a diagnosis of RA. Patients will be randomly allocated with a 1:1 ratio to IA or sham IA groups. Both groups will receive basic treatment and nursing routines for RA. The experimental group will receive actual IA treatment, whereas the control group will receive sham IA treatment. All patients will receive one course of treatment (i.e., four consecutive treatment sessions with an intervening 1-day interval). Primary outcomes will be traditional Chinese medicine (TCM) syndromes before and after a treatment course and Health Assessment Questionnaire (HAQ) scores. Secondary outcomes will be disease activity score 28 (DAS28) and levels of serum C-reactive protein (CRP). Outcome measures will be collected pre- and post-treatment.

Discussion

This study aims to provide high-quality evidence for the efficacy and safety of IA for treating RA. In addition, the results will provide references for selection of acupoints for other syndromes in clinical practice.

Efficacy of intradermal acupuncture for insomnia: a meta-analysis

OBJECTIVES

To provide updated evidence from randomized controlled trials (RCTs) on the efficacy of intradermal acupuncture for insomnia.

METHODS

A search of relevant literatures was performed on major medical databases, including the Cochrane Library, PubMed, EMBASE, CBM, CNKI, VIP, Wanfang Data and so on. Risk of bias evaluation, meta-analysis, sensitivity analysis and evidence rating of all extracted information were also conducted.

RESULTS

A total of 508 studies were initially identified. However, only 45 studies were deemed eligible for the present review. Meta-analyses were conducted in three comparisons separately: intradermal versus acupuncture, Effective rate (RR = 0.08, 95% CI -0.02 to 0.19), Global scales score (points) (SMD = -0.52, 95% CI: -0.81,-0.24, P = 0.02); intradermal acupuncture versus non acupuncture, Effective rate(RR = 1.22, 95% CI 1.04 to 1.42), Global scales score (points) (SMD = -0.81, 95% CI: -1.23,-0.38, P < 0.00001); control group versus control add intradermal acupuncture. Effective rate(RR = 1.27, 95% CI 1.13 to 1.42), Global scales score (points) (SMD = -1.15, 95% CI: -1.46,-0.84, P < 0.00001). Although these results suggested benefits of intradermal acupuncture, the overall quality of evidence rated was low.

CONCLUSIONS

The summary estimates indicate that it improved the clinical effective rate and lowered PSQI or other scales score, when compared to sham acupuncture or placebo/conventional medications/herbs.Also,it significantly improved the clinical effective rate and lowered PSQI or other scales score, when the control groups add intradermal acupuncture. However, the quality of the evidence is varied from very low to low due to the potential risk of bias and inconsistency among included trials. The more larger sample size and much more rigorous designed RCTs are still further studied.

Efficacy of Acupuncture for Insomnia: A Systematic Review and Meta-Analysis

Patients with insomnia frequently use acupuncture as an alternative treatment to pharmacotherapy globally. The aim of this paper is to assess the effect of acupuncture on insomnia. Seven medical databases, including MEDLINE, EMBASE, CENTRAL, CNKI, RISS, NDSL, and OASIS, were used to identify studies published through July 09, 2020. Twenty-four randomized controlled trials (RCTs) were included in this qualitative review comparing acupuncture to either pharmacotherapy or sham-acupuncture therapy. Methodological quality was assessed, using the Cochrane risk of bias (ROB). In the subsequent quantitative meta-analysis of studies comparing acupuncture versus pharmacotherapy, fifteen RCTs demonstrated that acupuncture had a significant effect on patients with insomnia as assessed by the Pittsburgh sleep quality index (PSQI) (RR: -0.74; 95% CI: -1.07 to -0.40; [Formula: see text] ¡0.0001; [Formula: see text] = 89%; [Formula: see text] = 1475). A subgroup analysis showed that there was no significant effect after weeks 1 and 2, but six studies found that acupuncture had a significant effect insomnia at week 3 (RR: -0.97; 95% CI: -1.65 to -0.28; [Formula: see text] = 0.006; [Formula: see text] = 91%; [Formula: see text] = 463) and nine studies demonstrated a significant effect at week 4 (RR: -0.70; 95% CI: -1.15 to -0.25; [Formula: see text] = 0.002; [Formula: see text] = 85%; [Formula: see text] = 594). These results suggest that insomnia patients may experience significant improvement in symptoms after more than three weeks of acupuncture treatment compared to pharmacological treatments.

Acupuncture treatment for post-stroke insomnia: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVES

The meta-analysis aimed to assess the effectiveness and safety of acupuncture for the treatment of post-stroke insomnia.

METHODS

Randomized controlled trials were identified from five databases before April 2020. The primary outcomes were the rate of improvement and the Pittsburgh sleep quality index (PSQI) scores; the secondary outcomes included the follow-up PSQI scores and safety.

RESULTS

Forty-one trials were included. Compared to drugs, the pooled results revealed that acupuncture had a higher rate of improvement in sleep (risk ratio: 1.21, 95% confidence interval [CI]: 1.17, 1.24) and a better PSQI score immediately and three months after treatment (weighted mean differences [WMD]: 3.23, 95%CI: 3.92, -2.54; and -6.18, 95%CI: 8.28, -4.07, respectively). Side effects were minor and rarely reported on acupuncture.

CONCLUSION

The existing evidence suggests acupuncture may be more effective in treating post-stroke insomnia than drugs. It also appears to have a good safety profile and more long-term benefits.

Sleep Disorders in Stroke: An Update on Management

Stroke is a leading cause of disability and mortality all over the world. Due to an aging population, the incidence of stroke is rising significantly, which has led to devastating consequences for patients. In addition to traditional risk factors such as age, hypertension, hyperlipidemia, diabetes and atrial fibrillation, sleep disorders, as independent modifiable risk factors for stroke, have been highlighted increasingly. In this review, we provide an overview of common types of current sleep disturbances in cerebrovascular diseases, including insomnia, hypersomnia, breathing-related sleep disorders, and parasomnias. Moreover, evidence-based clinical therapeutic strategies and pitfalls of specific sleep disorders after stroke are discussed. We also review the neurobiological mechanisms of these treatments as well as their effects on stroke. Since depression after stroke is so prevalent and closely related to sleep disorders, treatments of post-stroke depression are also briefly mentioned in this review article.

Dropouts in randomized clinical trials of Korean medicine interventions: a systematic review and meta-analysis

BACKGROUND

The dropout rate is an important determinant of outcomes in randomized controlled trials (RCTs) and should be carefully controlled. This study explored the current dropout rate in studies of Korean medicine (KM) interventions by systematic evaluation of RCTs conducted in the past 10 years.

METHODS

Three clinical trial registries (Clinical Research Information Service, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform) were searched to identify RCT protocols for KM interventions, such as acupuncture, herbal medicine, moxibustion, or cupping, and studies of mixed interventions, registered in Korea from 2009 to 2019. The PubMed, Embase, and OASIS databases were searched for the full reports of these RCTs, including published journal articles and theses. Dropout rates and the reasons for dropping out were analyzed in each report. The risk of bias in each of the included studies was assessed using the Cochrane risk of bias tool. The risk difference for dropping out between the treatment and control groups was calculated with the 95% confidence interval in a random effects model.

RESULTS

Forty-nine published studies were included in the review. The median dropout rate was 10% in the treatment group (interquartile range 6.7%, 17.0%) and 14% in the control group (interquartile range 5.4%, 16.3%) and was highest in acupuncture studies (12%), followed by herbal medicine (10%), moxibustion (8%), and cupping (7%). Loss to follow-up was the most common reason for dropping out. The risk difference for dropping out between the intervention and control groups was estimated to be 0.01 (95% confidence interval - 0.02, 0.03) in KM intervention studies.

CONCLUSIONS

This review found no significant difference in the dropout rate between studies according to the type of KM intervention. We recommend allowance for a minimum dropout rate of 15% in future RCTs of KM interventions.

The efficacy of acupuncture in postoperative sleep quality: a literature review

PURPOSE

General anesthesia may affect the quality of postoperative sleep, especially after surgery on elderly patients. The decline of postoperative sleep quality may produce harmful effects on the postoperative recovery of patients. In this review, we summarized the efficacy and potential mechanism of acupuncture on postoperative sleep quality.

METHODS

We review the effect of general anesthesia on circadian sleep rhythm. In addition, to provide evidence about the impairment of decreased postoperative sleep quality, we also emphasize the mechanism of acupuncture alleviates factors that affect sleep quality after general anesthesia.

RESULTS

The application of acupuncture technology has been helpful to improve sleep quality and alleviate postoperative complications affecting postoperative sleep quality after general anesthesia.

CONCLUSION

Acupuncture at different acupoints could effectively improve body's neurotransmitter levels and regulate biological clock genes through various mechanisms, and then improve postoperative sleep quality. Large-scale multi-center trials are needed to verify these findings.

Acupuncture or auricular electro-acupuncture as adjuncts to lifestyle interventions for weight management in PCOS: protocol for a randomised controlled feasibility study

BACKGROUND

Polycystic ovary syndrome (PCOS) is a prevalent women's health condition with reproductive, metabolic, and psychological manifestations. Weight loss can improve these symptoms and is a key goal; however, many women find this difficult to achieve. Acupuncture is a Chinese medical treatment that involves insertion of very fine metal needles into specific areas of the body and has been shown to be efficacious for weight loss in non-PCOS populations. However, few studies have been conducted in women with PCOS. A variant of acupuncture, auricular electro-acupuncture (AEA), may have beneficial effects on sympathetic tone, which is associated with insulin resistance, obesity and PCOS.

METHODS

This prospective three-arm open label parallel randomised controlled trial will assess feasibility and acceptability of acupuncture and/or AEA for weight loss in women with PCOS. We will enrol 39 women from the community aged between 18 and 45 years, with physician diagnosis of PCOS according to the Rotterdam criteria: body mass index (BMI) between 25 and 40 kg/m2. Women will be randomly allocated to receive one of three treatments for 12 weeks duration: body electro-acupuncture + lifestyle interventions, AEA + lifestyle interventions, or lifestyle interventions alone. The lifestyle intervention in this study is telephone-based health coaching (between 4 and 13 phone calls, depending on individual need), provided by the Get Healthy Service. Primary outcomes of the study are feasibility and acceptability of trial methods as determined by recruitment and retention rates, adherence, acceptability, credibility, and safety. Secondary outcomes include anthropometric (body weight, BMI, waist and hip circumference), metabolic (glucose tolerance and insulin sensitivity obtained from a 2-h 75 g oral glucose tolerance test with area under the curve insulin calculated using the trapezoid rule), reproductive (androgen levels, menstrual cyclicity, clinical hyperandrogenism using the Ferriman-Gallwey scoring system), autonomic (heart rate variability, blood pressure), lifestyle (physical activity levels, diet quality, weight self-efficacy), quality of life, and psychological (depression and anxiety symptoms, internal health locus of control).

DISCUSSION

This study addresses the feasibility and acceptability of novel interventions to treat overweight/obesity in PCOS. Study findings have the potential to generate a new understanding of the role of acupuncture and auricular acupuncture in weight management.

Feasibility of Acupuncture to Induce Sleep for Brainstem Auditory Evoked Response Testing

Purpose Brainstem auditory evoked response (BAER) testing is often performed under general anesthesia for children unable to complete behavioral audiologic evaluation. Alternatively, acupuncture treatment may be considered appropriate for BAER. Reports of acupuncture treatment in pediatric patients are scarce but are needed to demonstrate effectiveness. This study had 2 main objectives: (a) to examine the feasibility and effectiveness of acupuncture to achieve sleep to perform diagnostic BAER testing in medically complex (Cohort I) and nonmedically complex (Cohort II) children and (b) to assess acceptability to parents and audiologists of acupuncture as an alternative to anesthesia for BAER testing. Method A prospective feasibility study at Seattle Children's Hospital Outpatient Audiology Clinic from August 2015 through December 2018 was performed. A total of 31 pediatric patients were included. The median age for Cohort I was 29 months (interquartile range: 19-37 months), and the median age for Cohort II was 25.5 months (interquartile range: 16-32 months). Variables included number of BAER thresholds obtained, sleep indicators, and acceptability. The cost of BAER with acupuncture and the cost of BAER under anesthesia were compared. Results Acupuncture treatment effectively contributed to an adequate sleep state to obtain BAER results for most patients in both cohorts. Across cohorts, most patients (81%) fell asleep after acupuncture treatment. Complete test results were obtained in 48% of patients. Audiologists and parents reported high satisfaction rates with this procedure (87%). There were no adverse safety effects. Acupuncture treatment was less costly than anesthesia for BAER testing. Conclusions Acupuncture to induce sleep for BAER testing is effective, safe, and cost-efficient in small samples of medically and nonmedically complex pediatric patients. This procedure allowed earlier detection of hearing status and avoided potential adverse effects of anesthesia. Audiologists and parents reported that acupuncture treatment was an acceptable alternative to anesthesia for the BAER procedure.

Can Acupuncture Treatment of Hypertension Improve Brain Health? A Mini Review

With age, cerebrovascular and neurodegenerative diseases (e.g., dementia and Alzheimer’s) are some of the leading causes of death in the United States. Related to these outcomes is the increased prevalence of hypertension, which independently increases the development of cerebrovascular and neurodegenerative diseases. While a direct mechanistic link between hypertension and poor brain health is unknown, many hypothesize that the etiology stems from poor blood pressure (BP) and cerebrovascular regulation. This dysfunction fosters hypoperfusion of the brain, causing stress to the tissue through a nutrient mismatch, subtly damaging the brain over many years. Current Western medical treatment relies on pharmacological treatment (mainly beta-blockers, angiotensin-converting enzyme inhibitors, or a combination of the two). However, Western treatments have not been successful in mitigating brain health outcomes and are burdened with unwanted side effects and non-adherence issues. Alternatively, traditional East Asia medicine has used acupuncture as a treatment for hypertension and may offer a promising approach in response to the limitations of conventional therapy. While detailed clinical and mechanistic experimental evidence is lacking, acupuncture has been observed to reduce BP and improve endothelial function in hypertensive adults. Further, acupuncture has been shown to have specific cerebrovascular effects, increasing cerebrovascular reactivity in healthy adults, highlighting possible neuroprotective properties. Therefore, our review is aimed at evaluating acupuncture as a treatment for hypertension and the potential impact on brain health. We will interrogate the current literature as well as discuss the proposed neural and vascular mechanisms by which acupuncture acts.

Acupressure on Anxiety and Sleep Quality After Cardiac Surgery: A Randomized Controlled Trial

PURPOSE

To determine the effect of acupressure on anxiety and sleep quality after cardiac surgery.

DESIGN

A randomized pre-post test control group design.

METHODS

Patients after cardiac surgery were divided into two groups: the intervention group (n = 50), who received acupressure on four different acupoints plus standard care, and the control group (n = 50), who received only standard care. Patients were admitted to the surgical clinic from the intensive care unit after 3 or 4 days of surgery. The levels of anxiety and sleep quality were evaluated during three postoperative days starting from their first day in the surgical clinic.

FINDINGS

Among the patients in the intervention group, the usage of acupressure decreased the level of anxiety and increased the sleep quality significantly compared with the control group (P < .05).

CONCLUSIONS

Our findings showed that acupressure decreased the level of anxiety and improved the sleep quality in the surgical clinic after cardiac surgery.

Sleepless in the hospital: A systematic review of non-pharmacological sleep interventions

OBJECTIVE

Poor sleep is highly prevalent in inpatient medical settings and has been associated with attenuated healing and worsened outcomes following hospitalization. Although nonpharmacological interventions are preferred, little is known about the best way to intervene in hospital settings.

METHOD

A systematic review of published literature examining nonpharmacological sleep interventions among inpatients in Embase, PsycINFO and PubMed in accordance with PRISMA guidelines.

RESULTS

Forty-three of the 1529 originally identified manuscripts met inclusion criteria, encompassing 2713 hospitalized participants from 18 countries comprised of psychiatric and older adult patients living in hospital settings. Main outcomes were subjective and objective measures of sleep duration, quality, and insomnia.

CONCLUSIONS

Overall, the review was unable to recommend any specific intervention due to the current state of the literature. The majority of included research was limited in quality due to lack of controls, lack of blinding, and reliance on self-reported outcomes. However, the literature suggests melatonin and CBT-I likely have the most promise to improve sleep in inpatient medical settings. Additionally, environmental modifications, including designated quiet time and ear plugs/eye masks, could be easily adopted in the care environment and may support sleep improvement. More rigorous research in nonpharmacological sleep interventions for hospitalized individuals is required to inform clinical recommendations.

Effectiveness of Laser Acupuncture in Alleviating Chronic Insomnia: A Single-Blinded Randomized Controlled Trial

Study Objectives

This study investigates the therapeutic effect of Low Level Laser Therapy (LLLT) acupuncture for chronic insomnia.

Methods

Thirty-seven adult subjects with chronic insomnia were recruited and randomly assigned to three groups, namely, Group A (6 pairs of acupoints: Ex-HN 22, HT 7, SP 6, KI 3, LR 3, and PC 6, bilaterally distributed); Group B (acupoints as for Group A other than PC 6, which was applied only on the left side [i.e., the dominant side of the PC meridian] and the addition of DU 20, which is the main tonic acupoint for integration of all the meridians); and a control group (sham LLLT). The subjects in the treatment groups (i.e., Groups A and B) received LLLT acupuncture and those in the control group received sham LLLT for 15 minutes per session twice a week for five weeks. The sleep quality of all the subjects was evaluated using the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Hospital Anxiety and Depression Scale (HADS), and a sleep diary. In addition, the sympathetic activity before and after every treatment sessions was measured using the Heart Rate Variability (HRV).

Results

All three groups showed an improved PSQI score. However, only Group A showed a significant reduction in the sleep onset latency and number of awakenings at night and a higher sleep efficiency and ESS score. Furthermore, Group B showed an increased low frequency power and normalized low frequency of the HRV signal and a lower normalized high frequency power, suggesting an increased sympathetic activity and decreased parasympathetic activity.

Conclusions

For chronic insomnia insomniacs, LLLT appears to shorten the sleep latency, decrease the number of awakening events at night, and improve the sleep efficiency.

Assistive technology to enable sleep function in patients with acquired brain injury: Issues and opportunities

Introduction

Sleep disorders in patients with acquired brain injury are highly burdensome and associated with disability. An assistive technology framework emphasises the need to develop and apply a broad range of devices, strategies, and practices to ameliorate disabilities. We aimed to summarise scientific evidence regarding the utility of assistive technology in managing sleep disorders in patients with various causes of acquired brain injury.

Method

We retrieved articles before January 2016, through database searches of Medline, Embase, PsycINFO, CINAHL, and various bibliographies. The person–environment–occupation framework was used to analyse complex data pertaining to technology application and utility.

Results

We found 21 studies that described seven assistive technologies (continuous positive airway pressure, adaptive servo ventilator, nasotracheal suction mechanical ventilation, positioning devices, cognitive behavioural therapy, light therapy, and acupuncture) utilised in patients with acquired brain injury to manage sleep disorders.

Conclusion

Assistive technologies demonstrated effectiveness in alleviating and/or managing sleep disorders after acquired brain injury. Adherence to using the technology is limited by the level of injury-induced cognitive and physical impairment, technological regime, and environmental support. Development of user-friendly sleep-assistive technologies that take into consideration functional limitations and practice guidelines on structural communication between the occupational therapist, patient, and caregiver may facilitate patients’ self-determination in managing sleep disorders.

Effect of acupuncture on insomnia following stroke: study protocol for a randomized controlled trial

BACKGROUND

The incidence, mortality, and prevalence of stroke are high in China. Stroke is commonly associated with insomnia; both insomnia and stroke have been effectively treated with acupuncture for a long time. The aim of this proposed trial is to assess the therapeutic effect of acupuncture on insomnia following stroke.

METHODS

This proposed study is a single-center, single-blinded (patient-assessor-blinded), parallel-group randomized controlled trial. We will randomly assign 60 participants with insomnia following stroke into two groups in a 1:1 ratio. The intervention group will undergo traditional acupuncture that achieves the De-qi sensation, and the control group will receive sham acupuncture without needle insertion. The same acupoints (DU20, DU24, EX-HN3, EX-HN22, HT7, and SP6) will be used in both groups. Treatments will be given to all participants three times a week for the subsequent 4 weeks. The primary outcome will be the Pittsburgh Sleep Quality Index. The secondary outcomes will be: the Insomnia Severity Index; sleep efficacy, sleep awakenings, and total sleep time recorded via actigraphy; the National Institutes of Health Stroke Scale; the Stroke-Specific Quality of Life score; the Hospital Anxiety and Depression Scale. The use of estazolam will be permitted and regulated under certain conditions. Outcomes will be assessed at baseline, 2 weeks after treatment commencement, 4 weeks after treatment commencement, and at the 8-week follow-up.

DISCUSSION

This proposed study will contribute to expanding knowledge about acupuncture treatment for insomnia following stroke. This will be a high-quality randomized controlled trial with strict methodology and few design deficits. It will investigate the effectiveness of acupuncture as an alternative treatment for insomnia following stroke.

Acupuncture for stroke rehabilitation

BACKGROUND

Stroke is the second most common cause of death in the world and in China it has now become the main cause of death. It is also a main cause of adult disability and dependency. Acupuncture for stroke has been used in China for hundreds of years and is increasingly practiced in some Western countries. This is an update of the Cochrane review originally published in 2006 .

OBJECTIVES

To determine the efficacy and safety of acupuncture therapy in people with subacute and chronic stroke. We intended to test the following hypotheses: 1) acupuncture can reduce the risk of death or dependency in people with subacute and chronic stroke at the end of treatment and at follow-up; 2) acupuncture can improve neurological deficit and quality of life after treatment and at the end of follow-up; 3) acupuncture can reduce the number of people requiring institutional care; and 4) acupuncture is not associated with any intolerable adverse effects.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register (June 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane Library 2015, Issue 7), MEDLINE (1966 to July 2015, Ovid), EMBASE (1980 to July 2015, Ovid), CINAHL (1982 to July 2015, EBSCO), and AMED (1985 to July 2015, Ovid). We also searched the following four Chinese medical databases: China Biological Medicine Database (July 2015); Chinese Science and Technique Journals Database (July 2015); China National Infrastructure (July 2015), and Wan Fang database (July 2015).

SELECTION CRITERIA

Truly randomised unconfounded clinical trials among people with ischaemic or haemorrhagic stroke, in the subacute or chronic stage, comparing acupuncture involving needling with placebo acupuncture, sham acupuncture, or no acupuncture.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion, assessed quality, extracted and cross-checked the data.

MAIN RESULTS

We included 31 trials with a total of 2257 participants in the subacute or chronic stages of stroke. The methodological quality of most of the included trials was not high. The quality of evidence for the main outcomes was low or very low based on the assessment by the system of Grades of Recommendation, Assessment, Development and Evaluation (GRADE).Two trials compared real acupuncture plus baseline treatment with sham acupuncture plus baseline treatment. There was no evidence of differences in the changes of motor function and quality of life between real acupuncture and sham acupuncture for people with stroke in the convalescent stage.Twenty-nine trials compared acupuncture plus baseline treatment versus baseline treatment alone. Compared with no acupuncture, for people with stroke in the convalescent phase, acupuncture had beneficial effects on the improvement of dependency (activity of daily living) measured by Barthel Index (nine trials, 616 participants; mean difference (MD) 9.19, 95% confidence interval (CI) 4.34 to 14.05; GRADE very low), global neurological deficiency (seven trials, 543 participants; odds ratio (OR) 3.89, 95% CI 1.78 to 8.49; GRADE low), and specific neurological impairments including motor function measured by Fugl-Meyer Assessment (four trials, 245 participants; MD 6.16, 95% CI 4.20 to 8.11; GRADE low), cognitive function measured by the Mini-Mental State Examination (five trials, 278 participants; MD 2.54, 95% CI 0.03 to 5.05; GRADE very low), depression measured by the Hamilton Depression Scale (six trials, 552 participants; MD -2.58, 95% CI -3.28 to -1.87; GRADE very low), swallowing function measured by drinking test (two trials, 200 participants; MD -1.11, 95% CI -2.08 to -0.14; GRADE very low), and pain measured by the Visual Analogue Scale (two trials, 118 participants; MD -2.88, 95% CI -3.68 to -2.09; GRADE low). Sickness caused by acupuncture and intolerance of pain at acupoints were reported in a few participants with stroke in the acupuncture groups. No data on death, the proportion of people requiring institutional care or requiring extensive family support, and all-cause mortality were available in all included trials.

AUTHORS' CONCLUSIONS

From the available evidence, acupuncture may have beneficial effects on improving dependency, global neurological deficiency, and some specific neurological impairments for people with stroke in the convalescent stage, with no obvious serious adverse events. However, most included trials were of inadequate quality and size. There is, therefore, inadequate evidence to draw any conclusions about its routine use. Rigorously designed, randomised, multi-centre, large sample trials of acupuncture for stroke are needed to further assess its effects.

Acupuncture for insomnia after stroke: a systematic review and meta-analysis

BACKGROUND

Insomnia is the common complaint among patients with stroke. Acupuncture has increasingly been used for insomnia relief after stroke. The aim of the present study was to summarize and evaluate evidence on the effectiveness of acupuncture in relieving insomnia after stroke.

METHODS

Seven databases were searched from inception through October 2014 without language restrictions. Randomized controlled trials (RCTs) were included if acupuncture was compared to placebo or other conventional therapy for treatment of insomnia after stroke. Assessments were performed using the Pittsburgh sleep quality index (PSQI), the insomnia severity index (ISI), the Athens insomnia scale (AIS), and the efficacy standards of Chinese medicine.

RESULTS

A total of 165 studies were identified; 13 RCTs met our inclusion criteria. Meta-analysis showed that acupuncture appeared to be more effective than drugs for treatment of insomnia after stroke, as assessed by the PSQI (weighted mean difference, 4.31; 95 % confidence interval [CI], 1.67-6.95; P = 0.001) and by the efficacy standards of Chinese medicine (risk ratio, 1.25; 95 % CI, 1.12-1.40; P < 0.001). Intradermal acupuncture had significant effects compared with sham acupuncture, as assessed by the ISI (weighted mean difference, 4.44; 95 % CI, 2.75-6.13; P < 0.001) and the AIS (weighted mean difference, 3.64; 95 % CI, 2.28-5.00; P < 0.001).

CONCLUSIONS

Our results suggest that acupuncture could be effective for treating insomnia after stroke. However, further studies are needed to confirm the role of acupuncture in the treatment of this disorder.

Effect of Acupuncture on the Motor and Nonmotor Symptoms in Parkinson's Disease--A Review of Clinical Studies

Parkinson's disease is a neurodegenerative disorder. Parkinson's clinical feature is characterized by its motor manifestations, although its many nonmotor symptoms occur earlier and have more profound impact on the quality of patient's life. Acupuncture has been increasingly popular and has been used to treat patients with Parkinson's. In this article, we have studied the clinical reports of acupuncture treatment for Parkinson's, which were listed in Medline, PubMed, EMBASE, CNKI, and CINAHL databases in the past 15 years. It was found that acupuncture either manual or electroacupuncture stimulation at specific acupoints relieved some motor symptoms in patients with Parkinson's and markedly improved many nonmotor symptoms such as psychiatric disorders, sleep problems, and gastrointestinal symptoms. When it was used as an adjunct for levodopa, acupuncture improved therapeutic efficacy and reduced dosage and the occurrence of side effects of levodopa. However, the results were constrained by small sample sizes, methodological flaws, and blinding methods of studies. Although the evidence for the effectiveness of acupuncture for treating Parkinson's is inconclusive, therapeutic potential of acupuncture seems quite promising. More studies, either comparative effectiveness research or high-quality placebo-controlled clinical studies are warranted.

Comparison of the efficacy of aroma-acupressure and aromatherapy for the treatment of dementia-associated agitation

Background

One of the most common symptoms observed in patients with dementia is agitation, and several non-pharmacological treatments have been used to control this symptom. However, because of limitations in research design, the benefit of non-pharmacological treatments has only been demonstrated in certain cases. The purpose of this study was to compare aroma-acupressure and aromatherapy with respect to their effects on agitation in patients with dementia.

Methods

In this experimental study, the participants were randomly assigned to three groups: 56 patients were included in the aroma-acupressure group, 73 patients in the aromatherapy group, and 57 patients in the control group who received daily routine as usual without intervention. The Cohen-Mansfield Agitation Inventory (CMAI) scale and the heart rate variability (HRV) index were used to assess differences in agitation. The CMAI was used in the pre-test, post-test and post-three-week test, and the HRV was used in the pre-test, the post-test and the post-three-week test as well as every week during the four-week interventions.

Results

The CMAI scores were significantly lower in the aroma-acupressure and aromatherapy groups compared with the control group in the post-test and post-three-week assessments. Sympathetic nervous activity was significantly lower in the fourth week in the aroma-acupressure group and in the second week in the aromatherapy group, whereas parasympathetic nervous activity increased from the second week to the fourth week in the aroma-acupressure group and in the fourth week in the aromatherapy group.

Conclusions

Aroma-acupressure had a greater effect than aromatherapy on agitation in patients with dementia. However, agitation was improved in both of the groups, which allowed the patients with dementia to become more relaxed. Future studies should continue to assess the benefits of aroma-acupressure and aromatherapy for the treatment of agitation in dementia patients.

Microcurrent stimulation at shenmen acupoint facilitates EEG associated with sleepiness and positive mood: a randomized controlled electrophysiological study

To examine the electrophysiological effects of microcurrent stimulation at the Shenmen acupoint, 40 healthy normal subjects were randomly assigned to a placebo group (sham stimulation) and an experimental group (bilateral electrocutaneous stimulation at the Shenmen). The following two electroencephalographic indicators were used to measure brain activity. (1) Arousal level was measured with reference to log-transformed absolute alpha power and power source and analyzed using low-resolution electromagnetic tomography and (2) frontal alpha asymmetry was used as an indicator of mood. After real stimulation for 10 minutes, absolute alpha power was globally reduced in the experimental group, particularly in the anterior and centrotemporal regions of the brain. This indicates a decline in the brain activity associated with arousal. Moreover, the reduction was more prominent in the left frontal region, as compared to the right frontal region, resulting in significant increase from negative to positive frontal alpha asymmetry scores and reflecting an increase in the brain activity associated with enhanced mood. However, the placebo group exhibited no significant changes in two indicators after sham stimulation. This study provides initial electrophysiological evidence of changes in brain activity associated with reduced arousal (and thus greater sleepiness) and enhanced mood after microcurrent stimulation at the Shenmen acupoint.

Acupressure in insomnia and other sleep disorders in elderly institutionalized patients suffering from Alzheimer's disease

BACKGROUND

Sleep disorders are very common in elderly institutionalized people with dementia and acupressure recently has been associated with conventional medicine in their treatment.

AIMS

Exploring the effectiveness of acupressure for the treatment of insomnia and other sleep disturbances and we want to show that the acupressure treatment is feasible also in elderly resident patients.

METHODS

We enrolled institutionalized patients suffering from Alzheimer's disease with mild cognitive impairment and insomnia. A daily acupressure on HT7 point (H7 Insomnia Control(®)) was performed for a 8-week period. We administered the following scales: the mini mental state examination, the global deterioration scale, the neuropsychiatric inventory, the state-trait-anxiety inventory, the activity daily living and the instrumental activity daily living, the global health quality of life, and the Pittsburgh sleep quality index.

RESULTS

After receiving the acupressure treatment, patients saw a significant decrease of sleep disorders. The number of hours of effective sleep was perceived as increased. Furthermore, the time necessary to fall asleep decreased significantly and also the quality of sleep increased. Additionally, also the quality of life was bettered. Sedative drugs have been reduced in all patients involved in the study.

CONCLUSIONS

Acupressure can be recommended as a complementary, effective, and non-intrusive method to reduce sleep disturbances in old resident patients affected by cognitive disorders. A limitation of the study is the small sample size. More studies are needed to further validate the results of our study.

Effect of acupressure with valerian oil 2.5% on the quality and quantity of sleep in patients with acute coronary syndrome in a cardiac intensive care unit

The purpose of this three-group double-blind clinical trial study was to investigate the effect of acupressure (指壓 zhǐ yā) with valerian (纈草 xié cǎo) oil 2.5% on the quality and quantity of sleep in patients with acute coronary syndrome (ACS) in a coronary intensive care unit (CCU). This study was conducted on 90 patients with ACS in Mazandaran Heart Center (Sari, Iran) during 2013. The patients were randomly assigned to one of three groups. Patients in the acupressure with valerian oil 2.5% group (i.e., valerian acupressure group) received bilateral acupoint (穴位 xué wèi) massage with two drops of valerian oil for 2 minutes for three nights; including every point this treatment lasted in total 18 minutes. Patients in the acupressure group received massage at the same points with the same technique but without valerian oil. Patients in the control group received massage at points that were 1–1.5 cm from the main points using the same technique and for the same length of time. The quality and quantity of the patients' sleep was measured by the St. Mary's Hospital Sleep Questionnaire (SMHSQ). After the intervention, there was a significant difference between sleep quality and sleep quantity in the patients in the valerian acupressure group and the acupressure group, compared to the control group (p < 0.05). Patients that received acupressure with valerian oil experienced improved sleep quality; however, this difference was not statistically significant in comparison to the acupressure only group. Acupressure at the ear spirit gate (神門 shén mén), hand Shenmen, glabella (印堂 yìn táng), Wind Pool (風池 fēng chí), and Gushing Spring (湧泉 yǒng quán) acupoints can have therapeutic effects and may improve the quality and quantity of sleep in patients with ACS. Using these techniques in combination with herbal medicines such valerian oil can have a greater impact on improving sleep and reducing waking during the night.

Effect of acupuncture on patients with insomnia: study protocol for a randomized controlled trial

BACKGROUND

Hypnotic drugs tend to be the dominant form of treatment of insomnia, but these come with a number of reported side effects. Acupuncture has been studied as an alternative, resulting in a rising need for methodological research towards verifying its efficacy as insomnia treatment.

METHODS/DESIGN

We describe a proposal for a single-center, patient-assessor-blinded, randomized controlled trial with two parallel arms. A total of 38 patients complete screening tests at the first visit, are registered into the clinical trial, and then randomly assigned to the experimental or sham control groups (19 patients for each group). All subjects are clinical insomnia patients who score a 6 or above on the Pittsburgh Sleep Quality Index (PSQI) and meet all inclusion criteria. All subjects are treated with acupuncture and intradermal acupuncture (IDA) three times during the first week. Five sham acupoints are used in the control group. In the experimental group, five real acupoints (PC6, SP6, HT7, KI6, and BL62) are used unilaterally in turn. Sham acupoints are over 1 cm away from each real acupoint.The primary outcomes are the scores on the Insomnia Severity Index (ISI) and PSQI. Secondary outcomes are the sleep log, the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), the World Health Organization Quality of Life Abbreviated Version (WHOQOL-BREF), the Korean-Auditory Verbal Learning Test (K-AVLT), the Digit Span Test (DS), Event Related Potentials (ERPs) and heart rate variability (HRV) to assess emotional states, sleep quality, cognitive functioning, and electro-physiological changes.Subjects are assessed at three time points: baseline, post-treatment and follow-up. The duration of the clinical trial is 18 days.

DISCUSSION

To study the enhancement of the effectiveness of acupuncture for insomnia, we test the intradermal acupuncture method, which is performed continuously on the subject's skin and stimulated at home by the subject every night. In the trial, objective measurements including ERPs and HRV are used to evaluate states of cognition and autonomic nervous system functioning and subjective self-report questionnaires assess insomnia symptoms.'Sham' acupuncture points provided by STRICTA are used for the control group.

Does Acupuncture Reduce Stress Over Time? A Clinical Heart Rate Variability Study in Hypertensive Patients

Background: Heart rate variability (HRV), a noninvasive autonomic measure, has been applied to acupuncture interventions in controlled academic settings comparing points used, types of stimulation, or the HRV parameters measured. There is evidence that acupuncture decreases the stress response in both human and animal subjects, and can increase HRV in the short term (minutes to hours). Objectives: The goal of this study was to explore an array of HRV parameters during acupuncture sessions and over the course of treatment (weeks to months) in a series of patients being treated for hypertension. Materials and Methods: This was a retrospective, uncontrolled case study of patients presenting to a private acupuncture clinic. Patients received manual body acupuncture prescribed by the tenets of Traditional Chinese Medicine (TCM) and by published protocols for hypertension treatment. Heart rate was monitored during and after needle placement. The tracings were then analyzed with the Vivosense HRV analysis system. The main outcome measures were were patients' blood pressure measurements and low-frequency-to-high-frequency (LF/HF) ratio of HRV. Results: Patients tended to have an increase in their HRV during treatment, after needling, and, in some instances, an increase in HRV over weeks to months. Conclusions: Some patients' HRV increased over weeks to months during the course of acupuncture treatment for hypertension as evidenced by a decrease in their LF/HF ratio. This would indicate a relative decrease in their physiologic stress.

Effect of acupuncture on heart rate variability: a systematic review

Aim. To summarize all relevant trials and critically evaluate the effect of acupuncture on heart rate variability (HRV). Method. This was a systematic review with meta-analysis. Keyword search was conducted in 7 databases for randomized controlled trials (RCTs). Data extraction and risk of bias were done. Results. Fourteen included studies showed a decreasing effect of acupuncture on low frequency (LF) and low frequency to high frequency ratio (LF/HF ratio) of HRV for nonhealthy subjects and on normalized low frequency (LF norm) for healthy subjects. The overall effect was in favour of the sham/control group for high frequency (HF) in nonhealthy subjects and for normalized high frequency (HF norm) in healthy subjects. Significant decreasing effect on HF and LF/HF ratio of HRV when acupuncture was performed on ST36 among healthy subjects and PC6 among both healthy and nonhealthy subjects, respectively. Discussion. This study partially supports the possible effect of acupuncture in modulating the LF of HRV in both healthy and nonhealthy subjects, while previous review reported that acupuncture did not have any convincing effect on HRV in healthy subjects. More published work is needed in this area to determine if HRV can be an indicator of the therapeutic effect of acupuncture.

Integrative treatment modalities for stoke victims in Korea

OBJECTIVES

To suggest and discuss an integrative medicine model for stroke patients, we introduce our experience in Korea, describe treatment modalities used for stroke in Korean medicine, and present safety data on integrative care.

SUMMARY

For inpatients, integrative management is applied at the request of the primary physician with the consent of patients or their families. In the acute stage, neurologists or neurosurgeons take charge as the primary physicians. Korean medicine doctors cooperate as secondary physicians to the neurologists and neurosurgeons. After the acute stage, responsibilities are exchanged. The rehabilitation program is conducted under the supervision of rehabilitation medicine doctors. The most frequently used complementary and alternative medicine modalities are acupuncture (including manual acupuncture, electroacupuncture and intradermal acupuncture), moxibustion, herbal prescriptions, and acupuncture point injection.

CONCLUSION

Based on our field experiences, we believe it is worthwhile to continue efforts to integrate complementary and alternative medicine and Western medicine.

Effects of acupuncture on the symptoms of anxiety and depression caused by premenstrual dysphoric disorder

OBJECTIVE

The objective of this investigation was to evaluate the effects of acupuncture and sham acupuncture on the symptoms of anxiety and depression brought on by premenstrual dysphoric disorder (PMDD).

METHODS

In a single-blind randomised clinical trial, 30 volunteers with PMDD were assigned alternately to group 1 (acupuncture) or group 2 (sham acupuncture), and completed an evaluation of symptoms of anxiety and depression using the Hamilton Anxiety (HAM-A) and Hamilton Depression (HAM-D) Rating Scales. The procedure was performed twice a week for two menstrual cycles, for a total of 16 attendances for each participant.

RESULTS

Before the intervention the mean HAM-A and HAM-D scores did not differ between groups. Following the intervention symptoms of anxiety and depression were reduced in both groups; however, the improvement was significant in group 1 compared to group 2, as shown by a mean reduction in HAM-A scores of 58.9% in group 1 and 21.2% in group 2 (p<0.001). The reduction in the mean HAM-D scores was 52.0% in group 1 and 19.6% in group 2, resulting in a significant difference (p=0.012).

CONCLUSIONS

The results suggest that acupuncture could be another treatment option for PMDD patients.

Acupuncture therapy for stroke patients

Acupuncture is one of the most important parts of Traditional Chinese Medicine, has been used for more than 3000 years as prevention and treatment for various diseases in China as well as in adjacent regions, and is widely accepted in western countries in recent years. More and more clinical trials revealed that acupuncture shows positive effect in stroke, not only as a complementary and alternative medicine for poststroke rehabilitation but also as a preventive strategy which could induce cerebral ischemic tolerance, especially when combined with modern electrotherapy. Acupuncture has some unique characteristics, which include acupoint specificity and parameter-dependent effect. It also involves complicated mechanism to exert the beneficial effect on stroke. Series of clinical trials have shown that acupuncture primarily regulates the release of neurochemicals, hemorheology, cerebral microcirculation, metabolism, neuronal activity, and the function of specific brain region. Animal studies showed that the effects of acupuncture therapy on stroke were possibly via inhibition of postischemic inflammatory reaction, stimulation of neurogenesis and angiogenesis, and influence on neural plasticity. Mechanisms for its preconditioning effect include activity enhancement of antioxidant, regulation of the endocannabinoid system, and inhibition of apoptosis. Although being controversial, acupuncture is a promising preventive and treatment strategy for stroke, but further high-quality clinical trials would be needed to provide more confirmative evidence.

Acupuncture for the treatment of insomnia

Insomnia appears to be a fast-spreading problem in the modern days, which not only affects people's living quality but also impairs people's working efficiency even causing disability. Pharmacological treatment is effective but frequently with significant side effects. Acupuncture is traditionally used for the treatment of insomnia in China and now is widely accepted in the Western countries. Many research works on clinical applications of acupuncture in the treatment of insomnia and the potential mechanisms underlying the acupuncture treatment have been reported. This chapter will try to provide a systematic review on the research findings. A number of clinical studies, mainly randomized controlled clinical trials, have shown positive effects in acupuncture treatment of insomnia. Some of the studies demonstrated that acupuncture treatment appeared to be better than conventional pharmacological drugs in the improvement of insomnia. These encouraging findings are limited by the qualities problems of the methodology used in these clinical studies. 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.

Effects of electroacupuncture on recent stroke inpatients with incomplete bladder emptying: a preliminary study

Background

Incomplete bladder emptying (IBE) is defined as having a postvoid residual (PVR) urine volume greater than 100 mL for 2 consecutive days. IBE is common in stroke patients and could necessitate indwelling or intermittent catheterization. The condition is correlated with urinary tract infections, which could impede rehabilitation progress and increase medical costs. Treatment for patients with IBE includes bladder retraining, biofeedback, medication, and botulinum toxin injection, but none of these interventions are completely effective.

Methods

All patients with acute stroke who were admitted to the rehabilitation ward between August 2010 and April 2011 were included in the study and their PVR urine volume was checked. Electroacupuncture (EA; 1 Hz, 15 minutes) was performed on the acupoints Sanyinjiao (SP6), Ciliao (BL32), and Pangguangshu (BL28) of stroke patients with IBE for a total of ten treatments (five times a week for 2 weeks). Bladder diaries, which included the spontaneous voiding and PVR urine volumes, were recorded during the course of treatment.

Results

The presence of IBE was not related to sex, history of diabetes mellitus, stroke type (hemorrhagic or ischemic), or stroke location (P > 0.05). Among the 49 patients in the study, nine (18%) had IBE, and seven of the stroke patients with IBE were treated with EA. Increased spontaneous voiding volume and decreased PVR urine volume were noted after ten sessions of EA.

Conclusion

EA may have beneficial effects on stroke survivors with IBE, thereby making it a potential safe modality with which to improve urinary function.

Acupuncture for insomnia

BACKGROUND

Although conventional non-pharmacological and pharmacological treatments for insomnia are effective in many people, alternative therapies such as acupuncture are widely practised. However, it remains unclear whether current evidence is rigorous enough to support acupuncture for the treatment of insomnia.

OBJECTIVES

To determine the efficacy and safety of acupuncture for insomnia.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, Dissertation Abstracts International, CINAHL, AMED, the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS), the World Health Organization (WHO) Trials Portal (ICTRP) and relevant specialised registers of the Cochrane Collaboration in October 2011. We screened reference lists of all eligible reports and contacted trial authors and experts in the field.

SELECTION CRITERIA

Randomised controlled trials evaluating any form of acupuncture for insomnia. They compared acupuncture with/without additional treatment against placebo or sham or no treatment or same additional treatment. We excluded trials that compared different acupuncture methods or acupuncture against other treatments.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed risk of bias. We used odds ratio (OR) and mean difference for binary and continuous outcomes respectively. We combined data in meta-analyses where appropriate.

MAIN RESULTS

Thirty-three trials were included. They recruited 2293 participants with insomnia, aged 15 to 98 years, some with medical conditions contributing to insomnia (stroke, end-stage renal disease, perimenopause, pregnancy, psychiatric diseases). They evaluated needle acupuncture, electroacupuncture, acupressure or magnetic acupressure.Compared with no treatment (two studies, 280 participants) or sham/placebo (two studies, 112 participants), acupressure resulted in more people with improvement in sleep quality (compared to no treatment: OR 13.08, 95% confidence interval (CI) 1.79 to 95.59; compared to sham/placebo: OR 6.62, 95% CI 1.78 to 24.55). However, when assuming that dropouts had a worse outcome in sensitivity analysis the beneficial effect of acupuncture was inconclusive. Compared with other treatment alone, acupuncture as an adjunct to other treatment might marginally increase the proportion of people with improved sleep quality (13 studies, 883 participants, OR 3.08, 95% CI 1.93 to 4.90). On subgroup analysis, only needle acupuncture but not electroacupuncture showed benefits. All trials had high risk of bias and were heterogeneous in the definition of insomnia, participant characteristics, acupoints and treatment regimen. The effect sizes were generally small with wide confidence intervals. Publication bias was likely present. Adverse effects were rarely reported and they were minor.

AUTHORS' CONCLUSIONS

Due to poor methodological quality, high levels of heterogeneity and publication bias, the current evidence is not sufficiently rigorous to support or refute acupuncture for treating insomnia. Larger high-quality clinical trials are required.

Is insomnia associated with suicidality in stroke?

OBJECTIVE

To evaluate the relationship between insomnia and suicidality (SI) in Chinese patients with first or recurrent stroke.

DESIGN

Cross-sectional survey.

SETTING

Acute stroke unit of a general hospital.

PARTICIPANTS

Patients (N=787) with acute ischemic stroke admitted to the acute stroke unit of a university-affiliated regional hospital in Hong Kong.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Suicidality (SI) was assessed with the Geriatric Mental State Examination at 3 months after subjects' index stroke. Insomnia symptoms were evaluated with a standard insomnia questionnaire. The association between insomnia symptoms and SI was examined and adjusted for potential confounders, including age, sex, marital status, previous stroke, depression, fatigue, Mini-Mental State Examination score, and neurologic deficits measured with the National Institutes of Health Stroke Scale.

RESULTS

Eighty-seven patients (11.1%) were found to have SI (SI group). Frequent awakening was significantly more common in the SI group than in the non-SI group and remained a significant predictor of SI in forward logistic regression analysis (odds ratio, 1.7) after adjusting for possible confounders.

CONCLUSIONS

These findings should alert clinicians to the potential danger of insomnia and the importance of its early identification and treatment in stroke patients.
