Acupuncture for the Treatment of Hiccups following Stroke: A Systematic Review and Meta-Analysis

Bibliometric analysis: Hot spots and frontiers in acupuncture treatment of cerebral infarction

OBJECTIVE

CiteSpace6.1.R2 is used to analyze the research status of acupuncture in the treatment of cerebral infarction, and to find relevant hot spots and frontiers.

METHODS

The researchers searched the Web of Science Core Collection database. The search date is from the establishment of the database to August 31, 2023. The search terms and expressions are: ("Cerebral Infarction" OR "Ischemic stroke") AND ("Acupuncture" OR "fire needle"). The researchers used CiteSpace software to draw a knowledge map to explore the hot spots and frontiers of acupuncture in treating cerebral infarction.

RESULTS

We screened 414 articles in the Web of Science Core Collection database. China is the country with the largest number of publications, with a total of 343 papers published. China's institutions cooperate most closely, and cooperation between countries is less and more scattered. The author with the highest number of published articles is Chen L, with a total of 31 published articles. The research focus mainly revolves around the mechanism of acupuncture treatment of cerebral infarction and electroacupuncture treatment of cerebral infarction. Among them, acupuncture treatment of cerebral infarction is the most.

CONCLUSION

According to CiteSpace's analysis results, China is at the forefront of this research field, while other countries have less research in this field and little cooperation among countries. At present, the mainstream aspect of research is the mechanism of acupuncture treatment of cerebral infarction electroacupuncture and acupuncture points. Therefore, in future research, we should pay more attention to the treatment of cerebral infarction mechanism of acupuncture, problems with the type of acupuncture used, and acupuncture points.

Acupuncture in the treatment of post-stroke hiccup: A systematic Review and meta-analysis

Aim: Central hiccups following a stroke are a frequent complication, exerting adverse effects on both the stroke condition and the patient's daily life. Existing treatments exhibit limited efficacy and pronounced side effects. Acupuncture has been explored as a supplementary intervention in clinical practice. This study aims to investigate the clinical effectiveness of acupuncture for post-stroke hiccups.Methods: To identify published clinical randomized controlled trials addressing post-stroke hiccups treatment, comprehensive searches were conducted across PubMed, the Cochrane Library, EMBASE, Web of Science, Chinese Biological Medical (CBM), Wanfang Database, and China Science and Technology Journal (VIP). In addition, we scrutinized ClinicalTrials.gov and the Chinese Clinical Trial Registry. Employing Cochrane Handbook 5.1.0 and Review Manager 5.4 software, three authors independently reviewed literature, extracted data, and evaluated study quality. Data analysis was performed using Stata 16.0 and Review Manager 5.4.Results: A total of 18 trials were encompassed in the analysis. In comparison to standard treatment, acupuncture exhibited a significant enhancement in treatment effectiveness (RR: 1.27, 95% CI: 1.21-1.33; P < 0.00001). Notably, Hiccup Symptom Score displayed a considerable decrease (WMD: -1.28, 95% CI: -1.64 to -0.93; P < 0.00001), concurrent with a noteworthy improvement in the quality of life (WMD: 8.470, 95% CI: 7.323-9.617; P < 0.00001). Additionally, the incidence of adverse reactions decreased (RR: 0.45, 95% CI: 0.16-1.25; P = 0.13), and there was a significant reduction in SAS (WMD: -7.23, 95% CI: -8.47 - -5.99; P < 0.00001).Conclusions: Our investigation suggests that acupuncture could prove effective in post-stroke hiccup treatment. Nonetheless, due to concerns about the quality and size of the included studies, conducting higher-quality randomized controlled trials to validate their efficacy is imperative.

Verum versus Sham brain-computer interface on upper limb function recovery after stroke: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Previous clinical trials have reported that the brain-computer interface (BCI) is a useful management tool for upper limb function recovery (ULFR) in stroke. However, there is insufficient evidence regarding this topic. Thus, this study aimed to investigate the effectiveness of verum versus sham BCI on the ULFR in stroke patients.

METHODS

We comprehensively searched the Cochrane Library, PUBMED, EMBASE, Web of Science, and China National Knowledge Infrastructure databases from their inception to January 1, 2023. Randomized clinical trials (RCTs) assessing the effectiveness and safety of BCI for ULFR after stroke were included. The outcomes were the Fugl-Meyer Assessment for Upper Extremity, Wolf Motor Function Test, Modified Barthel Index, motor activity log, and Action Research Arm Test. The methodological quality of all the included randomized controlled trials was evaluated using the Cochrane risk-of-bias tool. Statistical analysis was performed using RevMan 5.4 software.

RESULTS

Eleven eligible studies involving 334 patients were included. The results of the meta-analysis showed significant differences in the Fugl-Meyer Assessment for Upper Extremity (mean difference [MD] = 4.78, 95% confidence interval [CI] [1.90, 7.65], I2 = 0%, P = .001) and Modified Barthel Index (MD = 7.37, 95% CI [1.89, 12.84], I2 = 19%, P = .008). However, no significant differences were found on motor activity log (MD = -0.70, 95% CI [-3.17, 1.77]), Action Research Arm Test (MD = 3.05, 95% CI [-8.33, 14.44], I2 = 0%, P = .60), and Wolf Motor Function Test (MD = 4.23, 95% CI [-0.55, 9.01], P = .08).

CONCLUSION

BCI may be an effective management strategy for ULFR in stroke patients. Future studies with larger sample size and strict design are still needed to warrant the current findings.

Clinical application of electroacupuncture in enhanced recovery after surgery

Enhanced recovery after surgery (ERAS) is currently the recommended surgical strategy, the main content of which is to reduce perioperative stress response and postoperative complications through perioperative multimodal analgesia and intensive surgery. Since ERAS was introduced, many rehabilitation medicine teams have been deeply involved, including physical therapy, occupational therapy, nutrition therapy and psychological counseling. However, ERAS lacks several powerful means to address perioperative prognostic issues. Therefore, how to further improve the effects of ERAS, reduce perioperative complications and protect vital organ functions has become an urgent problem. With the continuous development of traditional Chinese medicine, electroacupuncture (EA) has been widely used in various clinical applications, and its efficacy and safety have been fully proved. Recent studies have shown that the application of EA in ERAS has had an important impact on rehabilitation researches. In terms of reducing complications, the therapeutic effects of EA treatment mainly include: reducing pain and the use of analgesics; Improvement of postoperative nausea and vomiting; Postoperative immune function treatment; Relieve anxiety and depression. In addition, EA also protects the recovery of physiological functions, including cardiovascular function, cerebrovascular function and gastrointestinal function, etc. To sum up, the complementary strengths of EA and ERAS will allow them to develop and combine. This review discusses the potential value and feasibility of EA in ERAS from the aspects of improving perioperative efficacy and protecting organ functions.

Acupuncture as a post-stroke treatment option: A narrative review of clinical guideline recommendations

BACKGROUND

Acupuncture may be useful to treat the various clusters of symptoms occurring after a stroke. The use of evidence to underpin clinical practice and treatment guidelines (CPGs and TGs respectively) varies from country to country and may affect what recommendations are made by guideline developers.

PURPOSE

To examine the extent to which international clinical and treatment guidelines on post-stroke treatment mention the role of acupuncture and to identify what symptoms they recommend for its use.

METHOD

Scoping of national and international websites of CPGs and TGs r on the after care and rehabilitation of stroke patients provided by professional and government organisations was conducted. The presence/absence of recommendations and the underpinning evidence was appraised for the use of acupuncture for symptoms following stroke.

RESULTS

Of 84 CPGs and TGs on post stroke after-care identified from 27 countries between 2001 and 2021, 49 made statements about acupuncture. Positive recommendations on the use of acupuncture were identified for 15 symptom areas from 11 countries for: stroke rehabilitation, dysphagia, shoulder pain, motor recovery, walking, balance, spasticity, upper limb extremity impairment, post-stroke pain, central post stroke pain, cognitive disorder, depression, and sleep problems. Thirty-five CPGs (2001-2018) from 18 countries published over the same period were identified that made no mention of acupuncture and therefore no recommendations were made on its use.

CONCLUSIONS

Currently, evidence used by international guideline developers varies and this influences whether a positive or negative recommendation is made. Recommendations to use acupuncture should be based on the best available evidence which has been quality appraised.

Effective Treatment of Intraoperative Hiccups With Chlorpromazine Under General Anesthesia Without Muscle Relaxants: A Case Report

Hiccups are common reflexes and many treatment methods have been reported. Chlorpromazine is a known treatment option for hiccups, but its efficacy under general anesthesia remains unclear. We report the case of a patient with vagal schwannoma who developed hiccups while under general anesthesia. Muscle relaxants were not used because the patient was under neuromonitoring. The depth of anesthesia was deepened; however, the hiccups did not disappear. The hiccups were relieved by intravenous chlorpromazine administration (total; 5 mg), which allowed for surgery under neuromonitoring. This case indicates that chlorpromazine may be effective to treat hiccups under general anesthesia.

Acupuncture Therapy on Patients with Flaccid Hemiplegia after Stroke: A Systematic Review and Meta-Analysis

Background

Acupuncture is a commonly used complementary treatment for flaccid hemiplegia caused by stroke, but evidences from previous randomized trials were inconclusive. The purpose of this study was to evaluate the efficacy and safety of acupuncture in a comprehensive synthesis.

Methods

We searched literature from eight databases from their inception to December 2020. We included randomized controlled trials of acupuncture for the treatment of flaccid hemiplegia following stroke. The meta-analysis was carried out using Review Manager 5.3 and Stata 16.0. The main indicator was the Fugl-Meyer Assessment scale. The modified Barthel Index scale, Quality Of Life Assessment scale, Mini-Mental State Examination scale, Berg Balance Scale, Neurological Deficit Assessment scale, and the treatment effective rate were used to measure the secondary indicators. Adverse events from individual studies were used to determine safety.

Results

Our search returned 7624 records, of which 27 studies involving a total of 1,293 patients fulfilled our inclusion criteria. To be noted, our results indicated that significant improvements in the scores of the primary indicator showed better clinical scores among the three groups with acupuncture than without acupuncture: acupuncture compared with rehabilitation, 13.53 (95% CI 11.65–14.41, P < 0.01); acupuncture plus rehabilitation compared with rehabilitation, 9.84 (95% CI 6.45–13.24, P < 0.01, I² = 98%); and acupuncture plus Western medicine therapy compared with Western medicine, 16.86 (95% CI 15.89–17.84, P < 0.01, I² = 38%), and the secondary indicators showed the same tendency.

Conclusion

Acupuncture was effective and safe in the patients with flaccid hemiplegia after stroke, although there was high heterogeneity between studies.

Efficacy of acupuncture for persistent and intractable hiccups: A protocol for systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Persistent and intractable hiccups are a common clinical symptom that cause considerable physical pain to patients and severely damage their quality of lives. An increasing number of studies have demonstrated that acupuncture applied at acupoints dominated by Cuanzhu (BL2) can be used as one of the nonpharmacological therapies for controlling intractable hiccups. However, there is insufficient evidence evaluating the safety and effectiveness of those interventions. Therefore, this study is intended to conduct a systematic review and meta-analysis to provide evidence for a further study investigating alternative treatment options for persistent and intractable hiccups.

METHODS AND ANALYSIS

Randomized controlled trials (RCTs) of adult patients aged >18 years who meet the criteria for intractable hiccup diagnosis will be included, regardless of gender, nationality, and education level. Eight electronic databases will be searched, including 4 Chinese databases (CNKI, SinoMed, Wanfang Database, and Chinese Scientific Journal Database), 4 English databases (Web of Science, Medline, Embase, and Cochrane Library), from their date of establishment to September 2020. Two independent reviewers will evaluate the title summary for each RCT. Disagreements will be discussed with a third commentator. Data integration, heterogeneity analysis, subgroup analysis, and sensitivity analysis, will be performed using R-3.3.2 software. The RevMan 5.3 software will be used for the meta-analysis, and the "risk of bias" assessment will be conducted based on the methodological quality of the included trials recommended by the Cochrane Handbook 5.1. The quality evaluation of this study will be completed by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).

RESULTS

This study will summarize all the selected trials aimed at estimating the effectiveness, as well as safety, of applying acupuncture at acupoints dominated by Cuanzhu (BL2) to persistent and intractable hiccups.

CONCLUSIONS

This systematic review will provide evidence to assess the validity and safety of applying acupuncture at acupoints dominated by Cuanzhu (BL2) for persistent and intractable hiccups, which may provide clinicians with more choices in the treatment of this disease.

Chronic Hiccups

PURPOSE OF REVIEW

Nearly 4000 patients will be admitted to hospital in the US this year for hiccups. Hiccups are controlled by a complex reflex arc between peripheral receptors and the brainstem. Any disruption along this pathway may produce hiccups. Typically, hiccups resolve spontaneously but in certain pathologies symptoms may persist. Persistent hiccups may be considered a sign of underlying pathology. The most common cause involves GERD.

RECENT FINDINGS

Based on etiologies, studies have shown that first-line therapy should use a proton pump inhibitor (PPI) and involve appropriate gastrointestinal consultation. If symptoms persist, other etiologies such as central causes need to be explored.

SUMMARY

We review the pathophysiology of hiccups including multiple causes and the appropriate work up for each. We review several studies examining new treatments, both pharmacological and interventional, that may help patients. Initial therapy should still involve a PPI but several new therapies may be beneficial.

Intraoperative Laryngeal Mask Airway-Related Hiccup: An Overview

Hiccup is an involuntary contraction of the diaphragm and intercostal muscles resulting in sudden inspiration and closure of the glottis. The presence of hiccup in the perioperative period can be a challenging problem. Sudden movements of the patient from hiccups can interfere preoperative diagnostic procedures, intraoperative hiccup may delay the beginning of surgery, interfere with the surgical process, and affect intraoperative monitoring, and postoperative hiccup may affect would healing and hemodynamic stability. Hiccup can lead to have increased aspiration risk. Hiccup are is an incompletely understood phenomenon with multiple etiologies. Intraoperative hiccup related to laryngeal mask airway placement has been reported, and it presents unique challenges in diagnosis and management. Both pharmacological and non-pharmacological interventions have been utilized with various level of success. All treatment strategies are primarily aimed at interrupting the hiccup reflex arc.

Acupuncture for overactive bladder in adults: a systematic review and meta-analysis

Background:

Overactive bladder is prevalent in adults over 40 years of age and its prevalence increases with age. The use of acupuncture in adults with overactive bladder is increasing globally. However, its effectiveness/efficacy and safety have not yet been confirmed.

Objective:

To determine the effectiveness/efficacy and safety of acupuncture and to identify the pattern of commonly used traditional acupuncture points in the management of overactive bladder in adults.

Methods:

Ten electronic English and Chinese language databases were systematically searched and two English together with four Chinese journals relevant to acupuncture were manually searched in libraries for randomised controlled trials (RCTs) of acupuncture for overactive bladder in adults from their inception to March 2017. The Cochrane risk of bias tool was used to assess the methodological quality of the RCTs. RevMan v.5.3 software was employed for data analysis.

Results:

Seven eligible trials involving 695 participants were included. Meta-analysis showed that acupuncture was comparable to drugs (tolterodine tartrate/solifenacin) in the reduction of micturition episodes over 24 hours (pooled standardised mean difference (SMD) 0.36, 95% CI −0.23 to 0.95; I2=83%), increase in voided volume of each micturition episode (pooled SMD −0.15, 95% CI −0.36 to 0.05; I2=0%), and reduction of overactive bladder symptom score (pooled SMD −0.23, 95% CI −1.30 to 0.85; I2=91%). In addition, acupuncture was not significantly different compared with placebo in the reduction of overactive bladder symptom score (pooled SMD −2.36, 95% CI −5.64 to 0.93; I2=97%). No serious adverse events were reported.

Conclusions:

No significant differences in effectiveness or efficacy were found between acupuncture and drug or between verum and sham acupuncture, respectively. Further high-quality studies are required.

Temporal effect of acupuncture on amino acid neurotransmitters in rats with acute cerebral ischaemia

BACKGROUND

Acupuncture stimulation at GV26 during the acute phase of cerebral ischaemia can effectively reduce brain damage induced by ischaemic injury. However, the time course of the effects of acupuncture stimulation has not yet been thoroughly studied.

OBJECTIVE

To investigate the effects of manual acupuncture (MA) on glutamic acid (Glu) and γ-aminobutyric acid (GABA) expression in the cerebrospinal fluid of rats with middle cerebral artery occlusion (MCAO) and determine whether there is a temporal effect of acupuncture on the treatment of cerebral ischaemia.

METHODS

We performed thread occlusion of the right middle cerebral artery in rats to establish an animal model of MCAO. Simultaneously, during acupuncture treatment, microdialysis was used to continuously and dynamically observe immediate alterations in amino acid metabolism with acupuncture stimulation after cerebral ischaemia in vivo in this rat model of MCAO.

RESULTS

We found that, in comparison with an untreated MCAO group, Glu content was significantly decreased during the first acupuncture stimulation and during the course of the acupuncture treatment in the MCAO+MA group (MCAO vs MCAO+MA: day 1, P=0.032; day 2, P=0.021; day 3, P=0.017). These findings were also seen after the end of treatment when acupuncture was no longer applied (MCAO vs MCAO+MA: day 7, P=0.009). Measurements of GABA content following cerebral ischaemic injury showed that GABA peaks 24 hours after damage, falls thereafter and decreases to baseline levels on day 7. In the MCAO+MA group, GABA content on days 1 to day 2 was lower than in the MCAO group (MCAO+MA vs MCAO: day 1, P=0.003; day 2, P=0.001), although it was higher than in the control group (MCAO+MA vs control: day 1, P=0.024; day 2, P=0.009). GABA content on day 3 and day 7 was higher in the MCAO+MA group than in the MCAO group and the control group (MCAO+MA vs MCAO: day 3, P=0.008; day 7, P=0.013; MCAO+MA vs control: day 3, P=0.002; day 7, P=0.009).

CONCLUSION

Acupuncture stimulation at GV26 can effectively decrease excessive release of Glu induced by ischaemia and maintain the endogenous inhibitory activity of GABA. This phenomenon was seen during the entire course of acupuncture treatment and continued for some time after the end of acupuncture treatment.

Acupuncture attenuates cognitive impairment, oxidative stress and NF-κB activation in cerebral multi-infarct rats

BACKGROUD

Patients with multiple infarct dementia (MID) have subtle deficits that commonly go unnoticed, and are at risk of developing Alzheimer's disease. Oxidative stress induced by ischaemic injury results in intracellular calcium accumulation and neuronal apoptosis, leading to cognitive impairment by triggering various cellular signal transduction pathways. Several studies have suggested that NF-κB in the presence of p53 has a pro-apoptotic function in various models, but the mechanism is unclear.

AIMS

The aim of this study was to investigate whether acupuncture could protect cognitive function against cerebral multi-infarction (CMi) induced oxidative stress by inhibiting the activation of NF-κB and its target gene p53.

METHODS

An animal model of CMi was established by injecting homologous blood emboli into the right internal carotid artery of male Wistar rats. After 2 weeks of acupuncture treatment, cognitive function was detected by novel object recognition. Electron spin resonance and Fluo-3 fuorescence imaging were used to test the generation of ROS and intracellular calcium accumulation, respectively. Expression of NF-κB and p53 was examined by Western blot analysis and immunofluorescence.

RESULTS

CMi induced spatial learning and memory impairment, overproduction of intracellular hydroxyl radicals, and elevations of Ca²⁺, which were ameliorated by verum acupuncture treatment. Acupuncture inhibited activation of NF-κB and its downstream target gene p53.

CONCLUSION

These findings suggest that acupuncture could protect cognitive function against oxidative stress induced by CMi, which is partially associated with suppression of NF-κB-p53 activation.

Treatment of persistent hiccups after arthroplasty: effects of acupuncture at PC6, CV12 and ST36

OBJECTIVE

There are multiple treatment options for hiccups, including non-pharmacological therapies, but little evidence of superiority of one treatment over another. The aim of this study was to investigate the effects of acupuncture on persistent hiccups after arthroplasty.

METHODS

From April 2010 to December 2015, 15 patients with primary unilateral total hip/knee arthroplasty were diagnosed with persistent hiccups and given acupuncture at PC6, CV12 and ST36. Each acupuncture session lasted 30 min. The total number of treatment sessions was determined by the persistence of symptoms, but acupuncture was administered no more than three times over the course of a week. The hiccups assessment instrument (HAI) was used to assess the severity of hiccups pre-treatment and post-treatment. Adverse events were also recorded.

RESULTS

Absolute resolution was observed in all 15 patients after less than three acupuncture sessions. Of these, 10 patients required only one acupuncture session, 3 patients required two sessions and 2 patients required three sessions. The HAI score improved after each round of acupuncture treatment (P<0.05). The average HAI score improved significantly post-acupuncture compared to baseline values pre-treatment (P<0.05). Symptoms accompanying the hiccups included pain in the diaphragmatic area (five patients), mild dyspnoea (three patients), dysphagia (two patients) and nausea/vomiting (one patient). All these accompanying symptoms disappeared at the point of resolution of the hiccups. There were no adverse effects related to acupuncture during the study period.

CONCLUSION

Based on our results, acupuncture may represent a potential treatment option for hiccups after arthroplasty. Caution must be exercised, however, given the lack of a control group. Accordingly, randomised controlled trials will be required to verify the efficacy and effectiveness of acupuncture for the treatment of hiccups.

Acupuncture for gender differences and similarities in cerebral activity of health volunteers: A pilot fMRI study

This study aimed to explore the feasible gender differences and similarities in cerebral activity response to the acupuncture at local acupoints around knee.Fifteen male and 15 female healthy adults were recruited and included in this study. Functional magnetic resonance imaging (fMRI) was applied to measure cerebral activity response to acupuncture at Liangqiu (ST34), Xuehai (SP-10), Neixiyan (EX-LE4), and Dubi (ST-35).Acupuncture activated the postcentral gyrus, precuneus, temporal, posterior lobe, and occipital lobe in both males and females. When compared with females, males showed brain activation in the right middle frontal gyrus, inferior frontal gyrus, right precuneus, right superior parietal lobule, left cerebellum anterior lobe; and brain deactivation in the right frontal. When compared with males, females were observed brain activation in the right frontal lobe, right parietal lobe, and right middle temporal gyrus; and brain deactivation in the left and right medial frontal gyrus.The results of this study demonstrated that the neural effects of local acupoints around knee might be different between male and female subjects. Further clinical trials should take this gender effect into account in their design of studies.

Overview of Treatment Guidelines and Clinical Practical Guidelines That Recommend the Use of Acupuncture: A Bibliometric Analysis

INTRODUCTION

As positive evidence emerges for the use of an intervention to treat a health problem, the intervention gradually becomes incorporated into treatment guidelines (TGs) or clinical practice guidelines (CPGs) that are related to that health problem. To assess whether this general hypothesis can apply to acupuncture, 96 health problems were identified for which positive conclusions in systematic reviews and meta-analyses regarding the effectiveness of acupuncture have been made and then searched for TGs or CPGs that have recommended the use of acupuncture.

METHODS

Through August 31, 2017, searches were performed in relevant medical databases and Google using "treatment guideline," "clinical practice guideline," and the names of the 96 medical conditions as search terms. A "snow-balling" search approach was adopted. All positive recommendations were added into the registry.

RESULTS

A total of 1311 publications were found that recommended using acupuncture published between 1991 and 2017. The number per year reached 50 in 2005 and 100 in 2009. In addition, 2189 positive recommendations were found for the use of acupuncture. Of these, 1486 were related to 107 pain indications and 703 were related to 97 nonpain indications. These recommendations were made by a wide range of groups, such as government health institutions, national guideline, and medical specialty groups. The recommendations came from around the world but were especially abundant in North America, Europe, and Australasia.

DISCUSSION AND CONCLUSION

Considerably more recommendations were found for the use of acupuncture than are known within the acupuncture or medical communities. A trend by year was also found; a rise in the number of positive statements about acupuncture was typically followed by a rise in the number of recommendations of acupuncture. Thus, the recommendations followed the emergent evidence for acupuncture. Better implementation plans need to be developed for the CPG/TG recommendations about acupuncture to be more effective/efficient.

Immediate effect of scalp acupuncture on the gait of patients with subacute intracerebral haemorrhage analysed by three-dimensional motion: secondary analysis of a randomised controlled trial

OBJECTIVE

To investigate the immediate effect of scalp acupuncture on walking pattern, using three-dimensional gait analysis (3D-GA), among patients in the subacute stage of intracerebral haemorrhage (ICH).

METHODS

A subset of 30 patients with subacute ICH participating in a recently published randomised controlled trial who were able to walk independently were assessed by 3D-GA before and immediately after scalp acupuncture treatment (treatment group) or no intervention (control group) and the results presented here as a secondary analysis. The acupuncture manipulation was repeated three times with an interval of 5 min. Spatiotemporal and kinematic parameters during walking were collected and analysed using a 3D motion analysis system.

RESULTS

After treatment, there were significant differences between the treatment and control groups in the spatiotemporal parameters of step length, velocity and cadence (p<0.05) and double-limb support. No significant difference was found in step width. When kinematic parameters were evaluated, the treatment group showed a significantly decreased peak pelvic anterior tilt angle and an increased hip extension angle after scalp acupuncture treatment, whereas the control group demonstrated no temporal changes. There were no significant changes in any other kinematic parameters in either group.

CONCLUSIONS

As the first exploratory study to investigate the effect of the scalp acupuncture on gait performance in patients with subacute ICH, this secondary analysis of a recent randomised trial suggested an immediate effect of treatment on spatiotemporal parameters. Improvement in gait pattern may be associated with a decreased anterior tilt of the pelvis and augmented hip joint motion during walking.

Management of hiccups in palliative care patients

Persistent hiccups are a frustrating experience for palliative care patients, and can have a profound impact on their quality of life. This article provides an evidence-based approach overview of the causes and treatment of this not infrequently debilitating condition for such patients, with a management algorithm. In situations where no readily reversible cause is identified, or where simple physical manoeuvres, such as breath holding have failed, a systematic approach is required. Hiccups can be broadly divided into central and peripheral types. These respond differently to pharmacological intervention. The drug of choice for central causes of persistent hiccups is baclofen, with metoclopramide recommended as the first choice for peripheral causes. Midazolam may be useful in cases of terminal illness. Interventional procedures such as vagal or phrenic nerve block or stimulation should be considered in patients who are refractory to medications. The management of persistent hiccups still presents an ongoing clinical challenge however, requiring further research on pathophysiology and treatment strategies. Multinational randomised controlled trials to evaluate and compare both current and new medications or procedures to better manage this difficult condition are suggested as a means of reaching this goal.
