“…Interestingly, there was no association between EMG variables and pain intensity same day, or pain exacerbation during the night. This latter result is in agreement with the similar observation in a study of tension headache patients, utilizing ambulatory monitoring of posterior neck and frontal muscles (Hatch et al 1991). The second, contrasting observation is that the commonly pain-free deltoid presented higher EMG amplitude and more sustained activity than trapezius.…”

“…It is generally accepted that sustained muscle activity can elicit pain (e.g., Simons and Mense 1998). Attempts have therefore been made to show an association between muscle activity during sleep and clinical conditions with muscle pain or with night-time pain exacerbation in these patient groups (Fischer and Chang 1985;Hatch et al 1991;Hyyppa¨and Kronholm 1995;Lavigne et al 1991;Lobbezoo et al 1996). The reported results are mostly negative; however, the assessment of nocturnal motor activity can be relatively crude, by electromyographic (EMG) recordings scored by visual inspection or detecting body movement by use of instrumented beds.…”

The study investigated the possible association between nocturnal trapezius muscle activity and shoulder and neck pain. Sixty female subjects participated in the study, 33 were classified as pain-afflicted on the basis of shoulder and neck pain reports for the previous 6 months. Electromyographic (EMG) activity was monitored bilaterally from the trapezius in all recordings. EMG recording of the deltoid, biceps, and hand flexors was included for 26 subjects (17 with pain) to provide a comparative basis for evaluation of the trapezius recordings. There was considerable variation in the amount of muscle activity between subjects; however, some subjects presented a continuous, low-level activity pattern throughout the presumed sleep period. Subjects classified as pain-afflicted had significantly higher activity level and longer duration of trapezius EMG activity than the pain-free subjects. The deltoid had significantly more activity than the trapezius, while the biceps and the hand flexors presented similar activity level and duration as the trapezius. Nocturnal trapezius activity was not associated with pain exacerbation the same night. We suggest nocturnal trapezius muscle activity is a pointer to physiological mechanisms that contribute to some forms of shoulder and neck pain, such as trapezius myalgia, but nocturnal muscle activity may not be casually implicated in the pain-induction process.

“…A stressful event, indeed, has been shown to precipitate a pain episode of TTH or migraine [7]. It has been hypothesized that a chronicizing stress, poor stress tolerance, prolonged physiological response to stressors or insufficient recovery from stress can cause headache, chronic pain and multiple physical disturbances [8]. These factors support the observations of the present study.…”

Headache prevalence in the population of L’Aquila (Italy) after the 2009 earthquake

et al. 2011

Stress induced by the events of daily life is considered a major factor in pathogenesis of primary tension-type headache. Little is known about the impact that could have a more stressful event, like a natural disaster, both in patients with chronic headache, both in people that do not had headache previously. The aim of the present study was to observe the prevalence of headache in the population following the devastating earthquake that affected the province of L’Aquila on April 6, 2009. The study population was conducted in four tent cities (Onna, Bazzano, Tempera-St. Biagio, Paganica). Sanitary access is recorded in the registers of medical triage, in the first 5 weeks, after the April 6, 2009. The prevalence of primary headache presentation was 5.53% (95% CI 4.2–7.1), secondary headache was 2.82% (95% CI 1.9–4.9). Pain intensity, assessed by Numerical Rating Scale score showed a mean value of 7 ± 1.1 (range 4–10). The drugs most used were the NSAIDs (46%) and paracetamol (36%), for impossibility of finding causal drugs. This study shows how more stressful events not only have an important role in determining acute exacerbation of chronic headache, but probably also play a pathogenic role in the emergence of primary headache. Also underlines the lack of diagnostic guidelines or operating protocols to early identify and treat headache in the emergency settings.

“…Most headache studies either recruit people who self-identify as frequent headache sufferers (eg, [38]), or those deemed at risk of frequent headaches (eg, [43,65,98]). Criteria for inclusion vary, but often involve the use of standardized assessment tools.…”

Methods for studying naturally occurring human pain and their analogues

Methods for investigating human pain have been developed over the last 100 years.Typically researchers focus on people with clinical pain, or on healthy participants undergoing laboratory controlled pain-induction techniques focussed mostly on exogenously generated skin nociception. Less commonly investigated are acute pain experiences that emerge naturally. Six common painful complaints were identified: headache, muscular pain, visceral pain, menstrual pain, dental pain, and pain associated with Upper Respiratory Tract Infection. Methods used to recruit participants with the natural occurrence of each pain complaint were identified, and features of their use reviewed. Also reviewed were experimental analogues designed to mimic these pains, with the exception of menstrual pain. Headache and menstrual pain appear to be most effectively researched in their naturally occurring form, whereas muscle and dental pain may be more easily induced. URTI and abdominal pain provide further challenges for researchers. Summary guidance is offered, and directions for methods development outlined.
