"Common" nonspecific headaches are the most frequent headaches in childhood and do not require a visit to the physician. Migraine is the most common of the headache syndromes with characteristic profiles, followed by the muscle contraction (tension), inflammatory and psychogenic types. Less frequent are mass or brain tumor headaches, malformation and hypertensive headaches. Migraine goes unrecognized more than the other common syndromes. Minor tranquilization may stop the pattern. The most important aspect of treatment for muscle contraction headache is recognition.

Twenty-eight patients suffering from severe, longstanding muscle contraction headache were randomly assigned to two groups, one receiving electromyographic (EMG) feedback therapy and the other, "most suitable alternative therapy." Headache intensity and severity as well as drug intake were reduced in the feedback group (p less than or equal to 0.01) as opposed to no improvement in the control group. The positive treatment effect in the feedback group persisted through a three-month follow-up period. EMG feedback therapy is effective in the treatment of muscle contraction headache even in its chronic, severe form, which is resistant to traditional treatment methods.

A survey of the literature is presented in two areas of biofeedback treatment for headache--muscle contraction and migraine--and a variety of miscellaneous pain syndromes. The studies done to date are characterized largely by lack of proper no-treatment or placebo control groups, by confounding biofeedback with a variety of other strategies, or by sample sizes too small to afford any reasonable conclusions about efficacy. There is some evidence that biofeedback works better for muscle contraction headache than false feedback, but it also appears that biofeedback is no more effective than relaxation training. The application of biofeedback to migraine or other pain syndromes remains of unproven value. Investigators seldom attempt to relate empirically their interventions to hypothetical models of pain mechanisms. The potential influence of extraneous factors linked to the therapeutic situation is pervasive in these studies, but examination of their specific roles in symptom reduction is largely missing. Some variables are listed which need to be examined and which may contribute to the alleviation of pain with much less expenditure of clinical resources than that demanded by biofeedback. Perhaps the main contribution of biofeedback has been to highlight such extraneous variables in the pain treatment setting.

The effect of cephalic vasomotor response (CVMR) and frontalis electromyographic (EMG) feedback on control of temporal arterial vasoconstriction and frontalis muscle activity in migraine and muscle contraction headache patients was investigated. A single subject multiple baseline design (across subjects and responses) was introduced to evaluate (1) patterning in the two physiological systems and (2) the effects of CVMR and EMG feedback on headache activity. The data indicated that (a) all four patients demonstrated an ability to control CVMR activity during CVMR feedback and EMG during EMG feedback, (b) idiosyncratic patterns of physiological activity emerge during feedback training, and (c) learned control of the pain mechanism for muscle contraction and migraine headaches was related to reduced frequency and duration of these headaches.

Serum dopamine-beta-hydroxylase (DBH) activity was measured during headache-free intervals in 17 patients with migraine and during the headache interval in 16 patients with muscle contraction headache, as well as in 40 normal subjects. The DBH activity was significantly higher in the migraine patients (46.5+/4.5 units) than in the controls (24.9+/2.4 units), whereas no significant difference was observed between the patients with muscle contraction headache (29.4+/4.5 units) and the controls.

Twenty-one patients experienced headache related to sexual activity. Two varieties of headache could be distinguished from the clinical histories. The first, developing as sexual excitement mount, had the characteristics of muscle contraction headache. The second, severe, throbbing or 'explosive' in character, occurring at the time of orgasm, was presumably of vascular origin associated with a hyperdynamic circulatory state. Two of the patients with the latter type of headache had each experienced episodes of cerebral vascular insufficiency on one occasion which subsequently resolved. A third patient in this category had a past history of drop attacks. No evidence of any structural lesion was obtained on clinical examination or investigation, including cerebral angiography in seven patients. Eighteen patients have been followed up for periods of two to seven years without any serious intracranial disorder becoming apparent. While the possibility of intracranial vascular or other lesions must always be borne in mind, there appears to be a syndrome of headache associated with sexual excitement where no organic change can be demonstrated, analogous to benign cough headache and benign exertional headache.

To investigate the pathophysiology of muscle contraction headache (MCH), several parameters of inflammation were evaluated in 48 patients suffering from MCH, and compared with 50 healthy control subjects: erythrocyte sedimentation rate; C-reactive protein; white blood cell count; immunoglobulin (Ig) G, A, M; and complement component 3(C3) and C4. Serum C3 and C4 levels were significantly elevated in MCH as compared to control subjects, but the other parameters did not differ significantly. This suggests that the inflammatory process may be involved in the production of MCH.

Substance abuse has been reported frequently in chronic headache patients. The problem exists in most Western countries. Abuse of various compounds frequently leads to a state of dependency. Prescription as well as over-the-counter agents are often abused. Aspirin, acetaminophen, and caffeine are the most frequently abused compounds. Butalbital, ergot alkaloids, NSAIDS, and narcotic and oral or intranasal sympathomimetics are often abused. Patients with chronic daily headache complain of symptoms that may suggest a mixed-type headache. Features of migraine and muscle contraction headache often coexist in these individuals. It has been suggested that the most frequent cause for the transformation of a periodic headache into a daily headache is substance abuse. Substance abuse and drug dependency have multiple causes, and the etiology will reside with the compounds that are used to excess. The problem may arise as a result of poor instructions from the physician, improper diagnosis with gradual escalation in amounts of drug consumed, or a reinforcement mechanism and a brain stimulation-reward effect. The brain reward system has been studied with narcotics and psychomotor stimulants. It may be activated to a lesser degree with ergotamine, barbiturates, and other abused substances. The long-term effects of substance abuse are contingent on the compounds that are used. They may result in organ damage, medical complications, vascular injury, and a refractory state with chronic headache that eludes successful management of the headache disorder. Patients exhibit a less-than-satisfactory quality of life and are often depressed. Treatment includes outpatient care in cooperative, less dependent patients. Often patients will require inpatient management in order to discontinue use of the abused agents. Pharmacologic agents, behavior modification, psychotherapy, dietary intervention, and acupuncture may be necessary to treat the patient. Each patient must be treated by an interested physician, and the patient will require one or more of the preceding measures for a successful outcome. Often abused compounds must be discontinued in order to obtain a satisfactory response in an individual with chronic headache.

Cause of muscle contraction headache (MCH) results from sustained contraction of scalp and posterior neck muscles. Recently, we published an effect of posture on the etiology of MCH. According to our data, head bending posture seems to be one of the main causes of sustained contraction of the posterior neck muscles. Wolff presented a hypothesis of ischemic contraction of these muscles as a cause of pain. However, about the blood flow of scalp or posterior neck muscles, only two reports were published so far. These two papers failed to demonstrate a reduction of blood flow in MCH patients, and neglected the effect of posture. The purpose of this report is to examine a change of blood flow of posterior neck muscles with the change of posture. A total of 40 patients with MCH were studied using laser doppler blood flow meter. Needle shaped probe with a diameter of 0.55 mm was inserted 15 mm into the posterior neck muscle. The angle between orbito-meatal line and horizontal plane were measured using a light helmet with goniometer. Surface EMG of the posterior neck muscles was recorded at the same time. In the case of controls who do not experience headache, the amplitude of EMG increases slightly with the bending posture (40 microV with OM line 20 degrees upward from the horizontal plane, 46 microV with OM line horizontal, and 52 microV when 30 degrees downward). In reverse to the increase of the EMG activity, blood flow of the neck muscles decreases (12 ml/100 g/min with OM line 20 degrees upward, 10.8 with OM line horizontal, 7.6 at 10 degrees down, 4.6 at 20 degrees down, and 4.1 at 30 degrees down).(ABSTRACT TRUNCATED AT 250 WORDS)

Many headache patients complain of poor sleep, and sleep disturbance has been shown to play a role in chronic pain. We recorded nocturnal sleep with a 4-channel cassette EEG monitoring device in 10 common migraine patients, 10 individuals with muscle contraction (tension) headache, and 10 chronic tension-vascular headache sufferers. Migraine patients had essentially normal sleep, although rapid eye movement (REM) sleep and REM latency were increased. Patients with tension headache had reduced sleep time and sleep efficiency, decreased sleep latency but frequent awakenings, increased nocturnal movements, and marked reduction in slow wave sleep, without change in REM sleep or latency. Mixed-element headaches with both tension and vascular features were associated with reduced sleep, increased awakening, diminished slow wave sleep, and REM sleep that was decreased in amount and reduced in latency. The findings suggest that patients with intermittent migraine may have minimal sleep disturbance, while chronic headache may be worsened by chronically poor sleep. Muscle contraction headache may be associated with frequent awakenings and decreased slow wave sleep similar to the sleep changes of fibrositis, while chronic tension-vascular headache may have a depressive substrate. Four-channel sleep recording may miss contributory sleep apnea, but nonetheless cassette EEG may facilitate outpatient evaluation of refractory headaches.
