BACKGROUND
Tension-type headache (TTH) is one of the most common primary headaches. Several studies have confirmed the efficacy of acupuncture therapies for TTH, but it is uncertain which treatment is most effective.
OBJECTIVE
This study aimed to compare the effectiveness and safety of different acupuncture therapies for TTH using Bayesian Network Meta-analysis to provide new ideas for treating TTH.
METHODS
Nine databases were searched for randomized controlled trials (RCTs) about different acupuncture therapies for TTH up to December 1, 2022. The outcome indicators analyzed in our study were total effective rate, visual analog scale (VAS), headache frequency, and safety. Pairwise meta-analysis and risk of bias assessment were performed using Review Manager 5.4. Stata 15.0 generated a network evidence plot and detected publication bias. Finally, a Bayesian network meta-analysis of the data was used by RStudio.
RESULTS
The screening process resulted in 30 RCTs that met the inclusion criteria, including 2,722 patients. Most studies failed to report details of trials and were therefore assessed as unclear risks. Two studies were considered high risk because they did not report on all pre-specified outcome indicators or had incomplete data on outcome indicators. The NMA results showed that for total effective rate, bloodletting therapy had the most considerable SUCRA value (0.93156136), for VAS, head acupuncture combined with Western medicine ranked first (SUCRA = 0.89523571), and acupuncture combined with herbal medicine was the most effective in improving headache frequency ( > 0.05).
CONCLUSION
Acupuncture can be used as one of the complementary or alternative therapies for TTH; bloodletting therapy better improves the overall symptoms of TTH, head acupuncture combined with Western medicine is more effective in reducing VAS scores, and acupuncture combined with herbal medicine seems to reduce headache frequency, but the difference is not statistically significant. Overall, acupuncture for TTH is effective with mild side effects, but future high-quality studies are still necessary.

Meta-Analysis Review
BACKGROUND
Acupuncture has been shown to reduce tension-type headache (TTH) frequency in previous studies. Nevertheless, repeated significance testing might inflate type I error. We aimed to verify the effectiveness and safety of acupuncture in reducing TTH frequency by meta-analysis and trial sequential analysis (TSA).
METHODS
Ovid Medline, Embase, and Cochrane Library were searched until September 29, 2022. Randomized controlled trials comparing acupuncture with sham acupuncture, no acupuncture, or other active therapies in adults with TTH were included. The primary outcome was TTH frequency. The secondary outcomes were responder rate and adverse event.
RESULTS
Fourteen studies involving 2795 participants were included. Acupuncture had more reduction than sham acupuncture in TTH frequency, both after treatment (standardized mean difference [SMD] - 0.80, 95% CI - 1.36 to - 0.24, P = 0.005) and at the follow-up period (SMD - 1.33, 95% CI - 2.18 to - 0.49, P = 0.002), while TSA showed the included sample size did not exceed required information size (RIS). Acupuncture was superior over no acupuncture after treatment (SMD - 0.52, 95% CI - 0.63 to - 0.41, P < 0.001), and cumulative sample size reached RIS. In terms of responder rate, acupuncture had a higher responder rate compared with sham acupuncture both after treatment (relative ratio [RR] 1.28, 95% CI 1.12 to 1.46, P = 0.0003) and the follow-up period (RR 1.37, 95% CI 1.19 to 1.58, P < 0.0001), but the sample size is inadequate.
CONCLUSION
Acupuncture is an efficacious and safe treatment for TTH prevention, but this conclusion might be limited by the generally very low to low quality evidence. TSA suggested that high-quality trials are needed to verify the efficacy and safety of acupuncture compared to sham acupuncture.

Headache Oct 2014To evaluate the association between tension-type headache and migraine with sleep bruxism (SB). (Review)
Review
AIM
To evaluate the association between tension-type headache and migraine with sleep bruxism (SB).
BACKGROUND
The association between SB and headaches has been discussed in both children and adults. Although several studies suggested a possible association, no systematic analysis of the available published studies exists to evaluate the quantity, quality, and risk of bias among those studies.
METHODS
A systematic review was undertaken, including articles that classified the headaches according to the International Classification of Headache Disorders and SB according to the criteria of the American Association of Sleep Medicine. Only articles in which the objective was to investigate the association between primary headaches (tension-type and migraine) and SB were selected. Detailed individual search strategies for The Cochrane Library, MEDLINE, EMBASE, PubMed, and LILACS were developed. The reference lists from selected articles were also checked. A partial grey literature search was taken by using Google Scholar. The methodology of selected studies was evaluated using the quality in prognosis studies tool.
RESULTS
Of 449 identified citations, only 2 studies, both studying adults, fulfilled the inclusion criteria. The presence of SB significantly increased the odds (study 1: odds ratio [OR] 3.12 [1.25-7.7] and study 2: OR 3.8; 1.83-7.84) for headaches, although studies reported different headache type.
CONCLUSION
There is not enough scientific evidence to either support or refute the association between tension-type headache and migraine with SB in children. Adults with SB appear to be more likely to have headache.

Meta-Analysis
BACKGROUND
Headache is one of the most common neurological symptoms. Many previous studies have indicated a relationship between primary headaches and alcohol. Drinking has been associated with increased risk of tension-type headache (TTH) and migraine. However, recently published studies have not confirmed this relationship. The existing literature is inconclusive; however, migraine patients avoid alcohol. Therefore, the primary objective was to provide a reliable assessment of alcohol intake in people with primary headaches; the secondary objective was to identify any potential relationship between alcohol consumption and headache risk.
METHODS
This study was based on PubMed, Embase and Web of Science database searches performed on 11 July 2023. This systematic review was registered in PROSPERO (CRD42023412926). Risk of bias for the included studies was assessed using the Joanna Briggs Institute critical appraisal tools. Meta-analyses were performed using Statistica software. The Risk Ratio (RR) was adopted as the measure of the final effect. Analyses were based on a dichotomous division of the respondents into "non-drinkers" and "drinkers" for headache patients and matched non-headache groups.
RESULTS
From a total of 1892 articles, 22 were included in the meta-analysis. The majority demonstrated a moderate or high risk of bias. The first part of the meta-analysis was performed on data obtained from 19 migraine studies with 126 173 participants. The risk of migraine in alcohol drinkers is approximately 1.5 times lower than in the group of non-drinkers (RR = 0.71; 95% CI: 0.57-0.89). The second part involved 9 TTH studies with 28 715 participants. No relationship was found between TTH diagnosis and alcohol consumption (RR = 1.09; 95% CI: 0.93-1.27). Two of the included cluster-headache articles had inconclusive results.
CONCLUSIONS
Alcohol consumption and migraine are inversely correlated. The exact mechanism behind this observation may indicate that migraine leads to alcohol-avoidance, rather than alcohol having any protective role against migraine. There was no relationship between TTH and drinking. However, further studies related to primary headaches and alcohol consumption with low risk of bias are required. Additionally, patients and physicians should consider the latest medical data, in order to avoid the myths about alcohol consumption and primary headaches.

Meta-Analysis
BACKGROUND
The role of inflammation and cytokines in the pathophysiology of primary headache disorders is uncertain. We performed a systematic review and meta-analysis to synthesise the results of studies comparing peripheral blood cytokine levels between patients with migraine, tension-type headache, cluster headache, or new daily persistent headache (NDPH), and healthy controls; and in migraine between the ictal and interictal stages.
METHODS
We searched PubMed/Medline and Embase from inception until July 2022. We included original research studies which measured unstimulated levels of any cytokines in peripheral blood using enzyme-linked immunosorbent assay or similar assay. We assessed risk of bias using the Newcastle-Ottawa Quality Assessment Scale. We used random effects meta-analysis with inverse variance weighted average to calculate standardised mean difference (SMD), 95% confidence intervals, and heterogeneity for each comparison. This study is registered with PROSPERO (registration number CRD42023393363). No funding was received for this study.
RESULTS
Thirty-eight studies, including 1335 patients with migraine (32 studies), 302 with tension-type headache (nine studies), 42 with cluster headache (two studies), and 1225 healthy controls met inclusion criteria. Meta-analysis showed significantly higher interleukin (IL)-6 (SMD 1.07, 95% CI 0.40-1.73, p = 0.002), tumour necrosis factor (TNF)-α (SMD 0.61, 95% CI 0.14-1.09, p = 0.01), and IL-8 (SMD 1.56, 95% CI 0.03-3.09, p = 0.04), in patients with migraine compared to healthy controls, and significantly higher interleukin-1β (IL-1β) (SMD 0.34, 95% CI 0.06-0.62, p = 0.02) during the ictal phase of migraine compared to the interictal phase. Transforming growth factor (TGF)-β (SMD 0.52, 95% CI 0.18-0.86, p = 0.003) and TNF-α (SMD 0.64, 95% CI 0.33-0.96, p = 0.0001) were both higher in patients with tension-type headache than controls.
CONCLUSIONS
The higher levels of the proinflammatory cytokines IL-6, IL-8 and TNF-α in migraine compared to controls, and IL-1β during the ictal stage, suggest a role for inflammation in the pathophysiology of migraine, however prospective studies are required to confirm causality and investigate the mechanisms for the increase in cytokine levels identified. Cytokines may also have a role in tension-type headache. Due a lack of data, no conclusions can be made regarding cluster headache or NDPH.

Meta-Analysis Review
BACKGROUND
Acupuncture is often used for prevention of tension-type headache but its effectiveness is still controversial. This is an update of our Cochrane review originally published in Issue 1, 2009 of The Cochrane Library.
OBJECTIVES
To investigate whether acupuncture is a) more effective than no prophylactic treatment/routine care only; b) more effective than 'sham' (placebo) acupuncture; and c) as effective as other interventions in reducing headache frequency in adults with episodic or chronic tension-type headache.
SEARCH METHODS
We searched CENTRAL, MEDLINE, EMBASE and AMED to 19 January 2016. We searched the World Health Organization (WHO) International Clinical Trials Registry Platform to 10 February 2016 for ongoing and unpublished trials.
SELECTION CRITERIA
We included randomised trials with a post-randomisation observation period of at least eight weeks, which compared the clinical effects of an acupuncture intervention with a control (treatment of acute headaches only or routine care), a sham acupuncture intervention or another prophylactic intervention in adults with episodic or chronic tension-type headache.
DATA COLLECTION AND ANALYSIS
Two review authors checked eligibility; extracted information on participants, interventions, methods and results; and assessed study risk of bias and the quality of the acupuncture intervention. The main efficacy outcome measure was response (at least 50% reduction of headache frequency) after completion of treatment (three to four months after randomisation). To assess safety/acceptability we extracted the number of participants dropping out due to adverse effects and the number of participants reporting adverse effects. We assessed the quality of the evidence using GRADE (Grading of Recommendations Assessment, Development and Evaluation).
MAIN RESULTS
Twelve trials (11 included in the previous version and one newly identified) with 2349 participants (median 56, range 10 to 1265) met the inclusion criteria.Acupuncture was compared with routine care or treatment of acute headaches only in two large trials (1265 and 207 participants), but they had quite different baseline headache frequency and management in the control groups. Neither trial was blinded but trial quality was otherwise high (low risk of bias). While effect size estimates of the two trials differed considerably, the proportion of participants experiencing at least 50% reduction of headache frequency was much higher in groups receiving acupuncture than in control groups (moderate quality evidence; trial 1: 302/629 (48%) versus 121/636 (19%); risk ratio (RR) 2.5; 95% confidence interval (CI) 2.1 to 3.0; trial 2: 60/132 (45%) versus 3/75 (4%); RR 11; 95% CI 3.7 to 35). Long-term effects (beyond four months) were not investigated.Acupuncture was compared with sham acupuncture in seven trials of moderate to high quality (low risk of bias); five large studies provided data for one or more meta-analyses. Among participants receiving acupuncture, 205 of 391 (51%) had at least 50% reduction of headache frequency compared to 133 of 312 (43%) in the sham group after treatment (RR 1.3; 95% CI 1.09 to 1.5; four trials; moderate quality evidence). Results six months after randomisation were similar. Withdrawals were low: 1 of 420 participants receiving acupuncture dropped out due to adverse effects and 0 of 343 receiving sham (six trials; low quality evidence). Three trials reported the number of participants reporting adverse effects: 29 of 174 (17%) with acupuncture versus 12 of 103 with sham (12%; odds ratio (OR) 1.3; 95% CI 0.60 to 2.7; low quality evidence).Acupuncture was compared with physiotherapy, massage or exercise in four trials of low to moderate quality (high risk of bias); study findings were inadequately reported. No trial found a significant superiority of acupuncture and for some outcomes the results slightly favoured the comparison therapy. None of these trials reported the number of participants dropping out due to adverse effects or the number of participants reporting adverse effects.Overall, the quality of the evidence assessed using GRADE was moderate or low, downgraded mainly due to a lack of blinding and variable effect sizes.
AUTHORS' CONCLUSIONS
The available results suggest that acupuncture is effective for treating frequent episodic or chronic tension-type headaches, but further trials - particularly comparing acupuncture with other treatment options - are needed.

Heliyon Jun 2024Acupuncture may be effective in treating tension-type headache (TTH). The durability of its effects after treatment completion remains inconclusive.
BACKGROUND
Acupuncture may be effective in treating tension-type headache (TTH). The durability of its effects after treatment completion remains inconclusive.
METHODS
We searched multiple databases and references from previous reviews for randomized controlled trials (RCTs) which investigated the effectiveness of acupuncture for TTH. We assessed the methodological quality of RCTs using the Cochrane Risk of Bias 2.0 (RoB 2) tool. Primary outcome was response rate, defined as the proportion of participants who reported at least a 50% reduction in monthly headache days from baseline after completion of treatment. Secondary outcomes included headache days, headache intensity, and analgesic use. Safety outcomes were also evaluated.
RESULTS
A total of seven RCTs involving 3,221 participants with frequent episodic and chronic TTH were included. Individuals receiving acupuncture reported a significantly higher response rate versus sham acupuncture (SA) immediately and at 1-6 months after completion of treatment (<0.05). Compared with SA, post-treatment results of headache days and headache intensity appeared consistent on the whole, showing associations favoring acupuncture. However, no significant reduction in analgesic use was found post-treatment. Acupuncture showed no superiority over physical training or relaxation training in headache days and headache intensity. Moreover, no serious adverse events associated with acupuncture were reported.
CONCLUSION
Limited evidence suggested that acupuncture might provide durable post-treatment effects in the management of frequent episodic and chronic TTH for up to 6 months compared with SA,with no severe treatment-related adverse events reported.

Associations Between Headache (Migraine and Tension-Type Headache) and Psychological Symptoms (Depression and Anxiety) in Pediatrics: A Systematic Review and Meta-analysis.
BACKGROUND
There have been no recent meta-analysis studies on specific psychological symptoms (depression and anxiety) according to the type of primary headache disorder in children and adolescents.
OBJECTIVES
We performed a meta-analysis of various psychodiagnostic scales. Psychological symptoms of primary headache disorders have been reported in previous studies.
STUDY DESIGN
A systematic review and meta-analysis.
METHODS
We conducted systematic reviews using the PubMed, Embase, Cochrane Library, and Scopus databases up to October 19, 2022. Ten studies were selected by applying the inclusion criteria. The psychological symptoms (depression and anxiety) of children and adolescents with migraine and tension-type headache (TTH) were compared with those of healthy controls using scale scores. All statistical analyses of the pooled data were performed using RevMan 5.3 software.
RESULTS
Psychodiagnostic tools to assess depression scored higher in patients with migraine than in healthy controls; however, most anxiety-related scores were not significantly different between the migraine and control groups. In contrast, anxiety-related scores were higher in patients with TTH than in healthy controls, but the score to measure the degree of depressive symptoms was not significantly different from the control group in patients with TTH.
LIMITATIONS
A limited number of studies for each scale were included. In addition, each scale has different sensitivities and specificities, which may have affected the results. In addition, we did not evaluate the differences in psychological symptoms according to the frequency and severity of headaches.
CONCLUSIONS
Depression is more associated with migraine; whereas, anxiety is more associated with TTH than healthy controls. Therefore, the screening and assessment of psychological symptoms should be performed in children and adolescents with primary headache disorders.

Review
BACKGROUND
Tension-type headache (TTH) affects about 1 person in 5 worldwide. It is divided into infrequent episodic TTH (fewer than one headache day per month), frequent episodic TTH (2 to 14 headache days per month), and chronic TTH (15 headache days a month or more). Ketoprofen is one of a number of analgesics suggested for acute treatment of headaches in frequent episodic TTH.
OBJECTIVES
To assess the efficacy and safety of ketoprofen for treatment of episodic TTH in adults compared with placebo or any active comparator.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and the Oxford Pain Relief Database up to May 2016, and also reference lists of relevant published studies and reviews. We sought unpublished studies by asking personal contacts and searching online clinical trial registers and manufacturers' websites.
SELECTION CRITERIA
We included randomised, double-blind, placebo-controlled studies (parallel-group or cross-over) using oral ketoprofen for symptomatic relief of an acute episode of TTH. Studies had to be prospective, with participants aged 18 years or over, and include at least 10 participants per treatment arm.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed studies for inclusion and extracted data. We used the numbers of participants achieving each outcome to calculate the risk ratio (RR) and number needed to treat for one additional beneficial outcome (NNT) or one additional harmful outcome (NNH) for oral ketoprofen compared to placebo or an active intervention for a range of outcomes, predominantly those recommended by the International Headache Society (IHS).We assessed the evidence using GRADE and created a 'Summary of findings' table.
MAIN RESULTS
We included four studies, all of which enrolled adults with frequent episodic TTH. They all specified using the IHS diagnostic criteria and reported mean baseline pain of at least moderate intensity. While 1253 people with TTH participated in these studies, the numbers available for any analysis were lower than this because outcomes were inconsistently reported and because many participants received active comparators.None of the included studies were at low risk of bias across all domains considered, although for most studies and domains this was likely to be due to inadequate reporting rather than poor methods. We judged one study to be at high risk of bias due to small size.Useful information was available only for ketoprofen 25 mg. For the IHS preferred outcome of being pain-free at two hours the NNT for ketoprofen 25 mg compared with placebo was 9.0 (95% confidence interval (CI) 4.8 to 72) in two studies (272 participants; low quality evidence). The NNT was 3.7 (95% CI 2.6 to 6.3) for pain-free or mild pain at two hours in two studies (272 participants; moderate quality evidence). Fewer people needed rescue medication with ketoprofen 25 mg than with placebo, with a number needed to treat to prevent one event (NNTp) of 6.2 (95% CI 4.3 to 11) in three studies (605 participants; moderate quality evidence). The number of participants reporting any adverse event was higher with ketoprofen 25 mg than placebo (NNH 15, (95% CI 8.7 to 45)) in three studies (651 participants with 66 events; low quality evidence). Most events were of mild to moderate intensity.Ketoprofen 25 mg was not different from paracetamol 1000 mg in two studies with 276 participants for any efficacy outcomes (low to moderate quality evidence); the RR for pain-free at two hours was 1.3 (95% CI 0.9 to 2.0). The number of participants reporting any adverse event was higher with ketoprofen 25 mg than with paracetamol (NNH 17, 95% CI 8.9 to 130)) in two studies (582 participants, 68 events; low quality evidence).Studies reported no serious adverse events.We judged the quality of the evidence comparing ketoprofen 25 mg with placebo or paracetamol 1000 mg as moderate to very low. Where evidence was downgraded it was because of the small number of studies and events.
AUTHORS' CONCLUSIONS
Ketoprofen 25 mg provided a small benefit compared with placebo in terms of being pain-free at two hours or having mild or no pain at two hours for people with frequent episodic TTH who have an acute headache of moderate or severe intensity. Its use was associated with more people experiencing adverse events. Ketoprofen 25 mg was not superior to paracetamol 1000 mg for any efficacy outcome.

Meta-Analysis Review
BACKGROUND AND PURPOSE
Tension-type headache (TTH) is one of the most common primary headache diseases in the world and has a serious negative impact on the physical and mental health of patients. Tuina is now widely used to treat tension-type headaches. This article aims to systematically review the evidence about the effectiveness of Tuina on the effectiveness rate, pain intensity, and impact of headache in individuals with TTH.
METHODS
Eight databases for randomized controlled trials (RCTs) of Tuina were included in treatments for TTH. Cochrane Collaboration's tool was applied to evaluate the quality of the studies. Confidence in the effect estimates was determined with the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) tool. We use the software STATA 12.0 for meta-analysis and TSA software for test sequence analysis.
RESULTS
Seven studies were included with a total sample of 1228 individuals. Meta-analysis results showed that Tuina was superior to drugs for improving the effectiveness rate (RR = 1.49, 95%CI: 1.25 to 1.77, p < 0.01, low evidence). A visual analog scale (VAS) score of Tuina was significantly lower than that of drugs (WMD = -0.738, 95% CI: -1.128 to -0.349, p < 0.01, moderate evidence). The trial sequential analysis showed that the effectiveness of Tuina for TTH was accurate. Adverse events were tolerable.
CONCLUSION
Tuina has a certain effect in treating tension headache. However, due to the low level of methodological quality included in the article, this conclusion should be considered cautiously. More studies are necessary to strengthen the evidence regarding the effectiveness and safety of Tuina for subjects with TTH.
