A multicentre, randomized clinical trial was undertaken to test the hypothesis that acupuncture is more efficacious than sham control procedure in the prevention of episodic tension-type headache. Fifty subjects were randomized to receive a course of treatment with either brief acupuncture or a sham procedure. Subjects were followed up for 3 months. Changes in headache were assessed by daily diary, the primary outcome measure being the number of days with headache. No significant differences were found between the changes in the two groups for any measure at any time point. Results also show that patient blinding was successful. In conclusion, this study does not provide evidence that this form of acupuncture is effective in the prevention of episodic tension-type headache. Thirty patients with tension-type headache were randomly chosen to undergo a trial of traditional Chinese acupuncture and sham acupuncture. Five measures were used to assess symptom severity and treatment response: intensity, duration and frequency of headache pain episodes, headache index and analgesic intake. The five measures were assessed during a 4 week baseline period, after 4 and 8 weeks of treatment, and 1, 6 and 12 months thereafter. Before the start of the study, each patient was administered the MMPI. Split-plot ANOVAs showed that, compared to baseline, at 1 month after the end of treatment and for the 12 month follow-up, the frequency of headache episodes, analgesic consumption and the headache index (but not the duration or intensity of headache episodes) significantly decreased over time; however, no difference between acupuncture and placebo treatment was found. No single MMPI scale predicted the response to treatment, but the mean MMPI profile of acupuncture non-responders showed the presence of 'Conversion V'. The aim of this study was to compare acupuncture, relaxation training and physical training in the treatment of chronic tension-type headache (CTTH). The study comprised 90 consecutive patients with CTTH who were randomly allocated to acupuncture, relaxation training or physical training. Headache intensity, headache-free days and headache-free periods were registered using a visual analogue scale and a headache diary. The measurements were made 4 weeks before, immediately after, and 3 and 6 months after the treatment period. Immediately after the last treatment, the number of headache-free periods and of headache-free days was higher in the relaxation group compared with the acupuncture group. There were no other significant differences between the groups at any time point. The clinical implications of our findings are that relaxation training induced the most pronounced effects directly after the treatment period, compared with acupuncture and physical training. A study with needle acupuncture was performed in tension-type headache employing a new placebo acupuncture
                Sixty-nine patients (mean age 48.1 years, SD = 14.1) fulfilling the International Headache Society criteria for tension-type headache were randomly assigned to verum or placebo condition. No significant differences between placebo and verum with respect to visual analogue scale and frequency of headache attacks could be observed immediately, 6 weeks and 5 months after the end of treatment. There was a significant but weak improvement in quality of life parameters (clinical global impressions, Nottingham Health Profile) after verum treatment. In decision tree analyses, the changes in clinical global impressions and headache frequency depended significantly on primary headache frequency with a limit value of 24.5 days headache per month. High values in the von Zerssen Depression Score resulted in high mean visual analogue scale values. Acupuncture treatment is frequently sought for tension-type headache (TTH), but there is conflicting evidence as to its effectiveness. This randomised, controlled, multicentre, patient-and observer-blinded trial was carried out in 122 outpatient practices in Germany on 409 patients with TTH, defined as > or =10 headache days per month of which < or =1 included migraine symptoms. Interventions were verum acupuncture according to the practice of traditional Chinese medicine or sham acupuncture consisting of superficial needling at nonacupuncture points. Acupuncture was administered by physicians with specialist acupuncture training. Ten 30-min sessions were given over a six-week period, with additional sessions available for partial response. Response was defined as >50% reduction in headache days/month at six months and no use of excluded concomitant medication or other therapies. In the intent-to-treat analysis (all 409 patients), 33% of verum patients and 27% of sham controls (p=0.18) were classed as responders. Verum was superior to sham for most secondary endpoints, including headache days (1.8 fewer; 95% CI 0.6, 3.0; p=0.004) and the International Headache Society response criterion (66% vs. 55% response, risk difference 12%, 95% CI: 2%-21%; p=0.024).). The relative risk on the primary and secondary response criterion was very similar ( approximately 0.8); the difference in statistical significance may be due to differences in event rate. TTH improves after acupuncture treatment. However, the degree to which treatment benefits depend on psychological compared to physiological effects and the degree to which any physiological effects depend on needle placement and insertion depth are unclear. To investigate the effectiveness of acupuncture compared with minimal acupuncture and with no acupuncture in patients with tension-type headache.
                Three armed randomised controlled multicentre trial.
                28 outpatient centres in Germany.
                270 patients (74% women, mean age 43 (SD 13) years) with episodic or chronic tension-type headache.
                Acupuncture, minimal acupuncture (superficial needling at non-acupuncture points), or waiting list control. Acupuncture and minimal acupuncture were administered by specialised physicians and consisted of 12 sessions per patient over eight weeks.
                Difference in numbers of days with headache between the four weeks before randomisation and weeks 9-12 after randomisation, as recorded by participants in headache diaries.
                The number of days with headache decreased by 7.2 (SD 6.5) days in the acupuncture group compared with 6.6 (SD 6.0) days in the minimal acupuncture group and 1.5 (SD 3.7) days in the waiting list group (difference: acupuncture v minimal acupuncture, 0.6 days, 95% confidence interval -1.5 to 2.6 days, P = 0.58; acupuncture v waiting list, 5.7 days, 3.9 to 7.5 days, P < 0.001). The proportion of responders (at least 50% reduction in days with headache) was 46% in the acupuncture group, 35% in the minimal acupuncture group, and 4% in the waiting list group.
                The acupuncture intervention investigated in this trial was more effective than no treatment but not significantly more effective than minimal acupuncture for the treatment of tension-type headache.

                To determine the effects of spinal manipulation therapy on adults with episodic tension-type headache.
                Randomized controlled trial lasting 19 weeks.
                Outpatient facility of a National Health Service-funded chiropractic research institution in Denmark.
                Volunteer sample of 26 men and 49 women aged 20 to 59 years who met the diagnostic criteria for episodic tension-type headache as defined by the International Headache Society.
                Participants were randomized into 2 groups, 1 receiving soft tissue therapy and spinal manipulation (the manipulation group), and the other receiving soft tissue therapy and a placebo laser treatment (the control group). All participants received 8 treatments over 4 weeks; all treatments were performed by the same chiropractor.
                Daily hours of headache, pain intensity per episode, and daily analgesic use, as recorded in diaries.
                Based on intent-to-treat analysis, no significant differences between the manipulation and control groups were observed in any of the 3 outcome measures. However, by week 7, each group experienced significant reductions in mean daily headache hours (manipulation group, reduction from 2.8 to 1.5 hours; control group, reduction from 3.4 to 1.9 hours) and mean number of analgesics per day (manipulation group, reduction from 0.66 to 0.38; control group, reduction from 0.82 to 0.59). These changes were maintained through the observation period. Headache pain intensity was unchanged for the duration of the trial.
                As an isolated intervention, spinal manipulation does not seem to have a positive effect on episodic tension-type headache. Sixty-two female patients with chronic tension headache were randomly divided into two treatment groups--acupuncture and physiotherapy. Their overall function (Sickness Impact Profile), and mental well-being (Mood Adjective Check List) and the intensity and frequency of headache were assessed before and after treatment. Before treatment the patients showed significantly more dysfunction and less positive mental well-being than a general population sample. Both treatment groups improved in overall function, the physiotherapy group somewhat more. The mental well-being increased only in the physiotherapy group. The intensity and frequency of headache was significantly reduced in both the physiotherapy group and the acupuncture group. The intensity of headache was significantly more improved in the physiotherapy group. The improvement of headache intensity persisted unchanged 7-12 months after treatment. We aimed to investigate the effectiveness of acupuncture in addition to routine care in patients with primary headache (> 12 months, two or more headaches/month) compared with treatment with routine care alone and whether the effects of acupuncture differ in randomized and non-randomized patients. In a randomized controlled trial plus non-randomized cohort, patients with headache were allocated to receive up to 15 acupuncture sessions over 3 months or to a control group receiving no acupuncture during the first 3 months. Patients who did not consent to randomization received acupuncture treatment immediately. All subjects were allowed usual medical care in addition to study treatment. Number of days with headache, intensity of pain and health-related quality of life (SF-36) were assessed at baseline, and after 3 and 6 months using standardized questionnaires. Of 15,056 headache patients (mean age 44.1 +/- 12.8 years, 77% female), 1613 were randomized to acupuncture and 1569 to control, and 11,874 included in the non-randomized acupuncture group. At 3 months, the number of days with headache decreased from 8.4 +/- 7.2 (estimated mean +/-s.e.) to 4.7 +/- 5.6 in the acupuncture group and from 8.1 +/- 6.8 to 7.5 +/- 6.3 in the control group (P < 0.001). Similarly, intensity of pain and quality of life improvements were more pronounced in the acupuncture vs. control group (P < 0.001). Treatment success was maintained through 6 months. The outcome changes in non-randomized patients were similar to those in randomized patients. Acupuncture plus routine care in patients with headache was associated with marked clinical improvements compared with routine care alone.
In the previous version of this review, evidence in support of acupuncture for tension-type headache was considered insufficient. Now, with six additional trials, the authors conclude that acupuncture could be a valuable non-pharmacological tool in patients with frequent episodic or chronic tension-type headaches.
