緊張型頭痛の治療はどのように行うか |
論文抄録 |
OBJECTIVE: To compare the effectiveness of spinal manipulation and pharmaceutical treatment (amitriptyline) for chronic tension-type headache. DESIGN: Randomized controlled trial using two parallel groups. The study consisted of a 2-wk baseline period, a 6-wk treatment period and a 4-wk posttreatment, follow-up period. SETTING: Chiropractic college outpatient clinic. PATIENTS: One hundred and fifty patients between the ages of 18 and 70 with a diagnosis of tension-type headaches of at least 3 months' duration at a frequency of at least once per wk. INTERVENTIONS: 6 wk of spinal manipulativetherapy provided by chiropractors or 6 wk of amitriptyline treatment managed by a medical physician. MAIN OUTCOME MEASURES: Change in patient-reported daily headache intensity, weekly headache frequency, over-the-counter medication usage and functional health status (SF-36). RESULTS: A total of 448 people responded to the recruitment advertisements; 298 were excluded during the screening process. Of the 150 patients who were enrolled in the study, 24 (16%) dropped out: 5 (6.6%) from the spinal manipulative therapy and 19 (27.1%) from the amitriptyline therapy group. During the treatment period, both groups improved at very similar rates in all primary outcomes. In relation to baseline values at 4 wk after cessation of treatment, the spinal manipulation group showed a reduction of 32% in headache intensity, 42% in headache frequency, 30% in over-the-counter medication usage and an improvement of 16% in functional health status. By comparison, the amitriptyline therapy group showed no improvement or a slight worsening from baseline values in the same four major outcome measures. Controlling for baseline differences, all group differences at 4 wk after cessation of therapy were considered to be clinically important and were statistically significant. Of the patients who finished the study, 46 (82.1%) in the amitriptyline therapy group reported side effects that included drowsiness, dry mouth and weight gain. Three patients (4.3%) in the spinal manipulation group reported neck soreness and stiffness. CONCLUSIONS: The results of this study show that spinal manipulative therapy is an effective treatment for tension headaches. Amitriptyline therapy was slightly more effective in reducing pain at the end of the treatment period but was associated with more side effects. Four weeks after the cessation of treatment, however, the patients who received spinal manipulative therapy experienced a sustained therapeutic benefit in all major outcomes in contrast to the patients that received amitriptyline therapy, who reverted to baseline values. The sustained therapeutic benefit associated with spinal manipulation seemed to result in a decreased need for over-the-counter medication. There is a need to assess the effectiveness of spinal manipulative therapy beyond four weeks and to compare spinal manipulative therapy to an appropriate placebo such as sham manipulation in future clinical trials. |

The primary aim of this study was to investigate which treatment, patient, and study characteristics are related to treatment outcome in tension headache. Literature on the subject was obtained by searching for articles published in English through CD-rom Compact Cambridge and PSYCHLIT (1970/1993) on the subjects of headache and tension or muscle contraction in combination with therapy or treatment. Inclusion criteria were prospective design, tension headache, > or = five subjects per condition; pre- and posttreatment scores available, subjects older than 16 years. Each article was independently reviewed and its data encoded by the two authors. Finally, 78 articles with 175 treated and nontreated conditions (total of 2,866 patients) were selected for this study. Meta-analysis revealed that cognitive therapy, relaxation, or electromyelographic (EMG) biofeedback alone or in combination with relaxation were superior to no treatment and to pseudo/placebo therapy. Pharmacological and other therapies were better than no treatment. However, restricting the analyses to studies using a headache diary, the results of pharmacological therapy were comparable to those of placebo therapy. Moreover, a better treatment outcome was found in studies with a relatively short duration of headache complaints (r -0.31) and with a relatively younger patient sample (r = -0.22). The year of publication was negatively related with improvement (r = -0.36). No relationship between treatment outcome and other treatment characteristics (duration, transfer of treatment), patient characteristics (gender, method of patient recruitment), and study characteristics (internal validity of the study, criteria for diagnosing tension headache, number of patients, drop-outs) was found. These findings suggest that treatment outcome may be affected more by patient characteristics than by treatment characteristics. Finally, some practical and research implications of these findings are discussed. |

In a controlled trial the effect of traditional Chinese acupuncture v. placebo acupuncture was evaluated in 18 patients with chronic tension headache (mean disease duration 15 years). All patients suffered from daily or frequently recurring headache, the intensity of which was recorded by the patient over a period of 15 weeks. Each patient was treated by traditional Chinese acupuncture as well as by placebo acupuncture in a cross-over design following randomization. Each period of treatment comprised six treatments. Traditional Chinese acupuncture was found to be significantly more pain-relieving than placebo acupuncture, according to the pain registration of the patients themselves. The pain reduction was 31%. Acupuncture is therefore found to be a reasonable treatment for chronic tension headache. |

The tricyclic antidepressant, amitriptyline, is an effective drug for the treatment of chronic tension-type headache and for other chronic pain syndromes, but it is also effective in the prophylaxis of an episodic type of headache such as migraine. However, its efficacy in episodic tension-type headache has not yet been clarified. We compared the efficacy of amitriptyline (25 mg/day) in 82 nondepressed patients with either chronic or episodic tension-type headache in an open-label study. Amitriptyline significantly reduced (P < 0.05) frequency and duration of headache as well as analgesic consumption in chronic, but not in episodic, tension-type headache. Further placebo-controlled trials, possibly with higher doses of amitriptyline, might confirm if the different pattern of response to amitriptyline can be explained in terms of different involvement of central nociception and of peripheral myofascial factors in the chronic and in the episodic forms of tension-type headache. |

INTRODUCTION: The mechanisms at play in the production of tension type headaches (TTH) are partially unknown. Some of the aspects that have been discussed in connection with this issue include genetic, vascular and biochemical factors and even a predisposition of certain personalities to suffer from this kind of pain. Yet, the relation between neurotransmitters like noradrenalin (NAd) and serotonin (5 HT) and chronic TTH (CTTH) seems to be quite clear and hence the use of antidepressants that act on these substances in the pharmacological treatment of CTTH. In this study, the qualitative and quantitative efficiency of amitriptyline is compared with that of mirtazapine (two antidepressants that act on NAd and 5 HT) in the prophylaxis of CTTH. |

The objective of this study was to evaluate and compare the efficacy and safety of single doses of acetaminophen (paracetamol) 1000 mg and naproxen 375 mg vs. placebo over a six-hour period in the treatment of tension-type headache. The treatments were compared in a randomized, double-blind, multicentre, placebo-controlled study. Efficacy was evaluated using four standard analgesic summary endpoints (the sum of pain intensity differences from baseline, the maximum pain intensity from baseline, the sum of the pain relief scores, and the maximum pain relief score). Both acetaminophen 1000 mg and naproxen 375 mg were significantly superior to placebo (P<or=0.009 and P<or=0.021, respectively) but not significantly different from each other (P>or=0.498) for these four endpoints. For example, the mean sum of pain intensity differences from baseline was 9.14+/-0.34 for acetaminophen 1000 mg and 8.81+/-0.35 for naproxen 375 mg compared with 7.42+/-0.34 for placebo. Other efficacy endpoints (percentage of responders (pain reduced to none) at two hours, onset of meaningful relief, time to use of rescue medication and subject's overall impression of study medication) showed similar trends. A significantly larger mean pain intensity difference from baseline was observed for acetaminophen 1000 mg (1.13) than for naproxen 375 mg (0.95) (P=0.036) at one hour after treatment. There was no significant difference among the treatment groups in the incidence of adverse events (P=0.730). In summary, the results of this well-controlled, double-blind study demonstrate that over-the-counter acetaminophen 1000 mg and prescription naproxen 375 mg are effective and well tolerated in the treatment of tough (moderate-to-severe) tension-type headache. |

Acute headache is a very frequent symptom, responsible for a significant percentage of caseload at primary care units and emergency rooms. Chlorpromazine is easily available in such settings. The aim of this study is to conduct a randomized, placebo-controlled, double-blind study to assess the efficacy of chlorpromazine on the acute treatment of episodic tension-type headache. We randomized 30 patients to receive placebo (10 ml of saline intravenous injections) and 30 patients to receive 0.1 mg/Kg chlorpromazine intravenously. We used 7 parameters of analgesic evaluation. Patients receiving chlorpromazine showed a statistically significant improvement (p < 0.05 and p < 0.01) of pain compared to placebo, far up to 30 minutes after the drug administration. The therapeutic gain was 36.7% in 30 minutes and 56.6 % in 60 minutes. The number needed to treat (NNT, the reciprocal or the therapeutic gain) was 2.7 in 30 minutes and 1.8 in 60 minutes. There were reductions in the recurrence and in the use of rescue medication in the chlorpromazine group. We can conclude that intravenous chlorpromazine is an effective drug to relief the pain in tension-type headache |

BACKGROUND: Chronic headache is a prevalent condition with substantial socioeconomic impact. Complementary or alternative therapies are increasingly being used by patients to treat headache pain, and spinal manipulative therapy (SMT) is among the most common of these. OBJECTIVE: To assess the efficacy/effectiveness of SMT for chronic headache through a systematic review of randomized clinical trials. STUDY SELECTION: Randomized clinical trials on chronic headache (tension, migraine and cervicogenic) were included in the review if they compared SMT with other interventions or placebo. The trials had to have at least 1 patient-rated outcome measure such as pain severity, frequency, duration, improvement, use of analgesics, disability, or quality of life. Studies were identified through a comprehensive search of MEDLINE (1966-1998) and EMBASE (1974-1998). Additionally, all available data from the Cumulative Index of Nursing and Allied Health Literature, the Chiropractic Research Archives Collection, and the Manual, Alternative, and Natural Therapies Information System were used, as well as material gathered through the citation tracking, and hand searching of non-indexed chiropractic, osteopathic, and manual medicine journals. DATA EXTRACTION: Information about outcome measures, interventions and effect sizes was used to evaluate treatment efficacy. Levels of evidence were determined by a classification system incorporating study validity and statistical significance of study results. Two authors independently extracted data and performed methodological scoring of selected trials. DATA SYNTHESIS: Nine trials involving 683 patients with chronic headache were included. The methodological quality (validity) scores ranged from 21 to 87 (100-point scale). The trials were too heterogeneous in terms of patient clinical characteristic, control groups, and outcome measures to warrant statistical pooling. Based on predefined criteria, there is moderate evidence that SMT has short-term efficacy similar to amitriptyline in the prophylactic treatment of chronic tension-type headache and migraine. SMT does not appear to improve outcomes when added to soft-tissue massage for episodic tension-type headache. There is moderate evidence that SMT is more efficacious than massage for cervicogenic headache. Sensitivity analyses showed that the results and the overall study conclusions remained the same even when substantial changes in the prespecified assumptions/rules regarding the evidence determination were applied. |

|
論文抄録 |
BACKGROUND: Studies in animals have shown that nitric oxide plays an important part in central sensitisation and that inhibitors of nitric oxide synthase (NOS) decrease sensitisation in models of persistent pain. The efficacy of inhibitors of NOS has not been tested in patients with tension-type chronic headache. We aimed to show whether N(G)-monomethyl-L-arginine hydrochloride (L-NMMA), an inhibitor of NOS, is effective in relieving pain in such patients. METHODS: We undertook a randomised double-blind, crossover trial of 16 patients with chronic-tension-type headache. Patients were assigned intravenous infusion of 6 mg/kg L-NMMA or placebo on 2 days separated by at least 1 week in a randomized order. Headache intensity was measured on a 100 mm visual analogue scale, and on a verbal rating scale at baseline and at 30 min, 60 min, and 120 min after start of treatment. The primary endpoint was reduction of pain intensity on the visual analogue scale by the active treatment compared with placebo. FINDINGS: L-NMMA reduced pain intensity on the visual analogue scale significantly more than placebo: 120 min after start of treatment, the mean pain score was decreased from 49 to 33 with L-NMMA and from 44 to 40 with placebo (p=0.01). Pain intensity on the verbal rating scale was also significantly lower for treatment with L-NMMA than for treatment with placebo (p=0.02). INTERPRETATION: Inhibition of NOS had an analgesic effect in chronic tension-type headache. Further tests are required before clinical application. |

CONTEXT: Episodic tension-type headache is common and is often treated using manual therapies. Few data exist for the efficacy of these interventions. OBJECTIVE: To determine the effects of spinal manipulation therapy on adults with episodic tension-type headache. DESIGN: Randomized controlled trial lasting 19 weeks. SETTING: Outpatient facility of a National Health Service-funded chiropractic research institution in Denmark . PARTICIPANTS: 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. INTERVENTION: 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. MAIN OUTCOME MEASURES: Daily hours of headache, pain intensity per episode, and daily analgesic use, as recorded in diaries. RESULTS: 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. CONCLUSION: As an isolated intervention, spinal manipulation does not seem to have a positive effect on episodic tension-type headache. |

75 人の ETTH 患者(月に 5 回以上 15 回以下, 0 から 100 の visual analogue scale で頭痛強度が 25 から 85 の間にある ETTH ) |
介入 |
指圧師によるマッサージと上部頚髄指圧を受ける指圧治療群とマッサージと低出力レザー光線照射をうける対照群の 2 群にわけて検討した. 4 週間にわたり合計 8 回の治療を行い,治療前後で 19 週にわたる臨床試験である. |
主要評価項目とそれに用いた統計学的手法 |
主要項目は,1日あたりの頭痛持続時間,発作毎の平均頭痛強度,日々の鎮痛剤使用回数である. ITT 解析を行った, |
結果 |
指圧群と対照群の間には有意差はなかった. |
結論 |
指圧自体に,単独治療として ETTH の有効性があるとは言い難い. |
