Low back pain (LBP) is a major problem of public health. Chronic pain is the most difficult to treat and the most expensive. The way patients cope with their pain may influence its outcome. ⋯ Besides somatic factors, psychosocial predictors of LBP chronic evolution may be identified. Both aspects must be taken into account in order to prevent chronic pain. Perhaps cognitive-behavior therapy may help LBP patients to cope with pain in a better way.

Comparative Study
A comparison of the relative utility of coping and acceptance-based measures in a sample of chronic pain sufferers.
Previous research suggests that to define the problem of chronic pain as a problem of coping may not be as useful as framing it as a problem of acceptance for some patients. The coping approach may encourage, or at least permit, a somewhat inflexible agenda of pain reduction or control while the acceptance approach may allow a more flexible agenda of willingness to have pain in some circumstances where that serves the goal of better life functioning. The purpose of this study was to continue to examine the relative utility of concepts of coping and acceptance of pain. ⋯ Correlation results showed that the acceptance variables were reliably stronger predictors of distress and disability compared with coping variables. Regression analyses confirmed that, compared with coping variables, acceptance accounted larger unique increments in variance in measures of patient functioning regardless of whether the coping variables were given priority in the regression equations. Increasing data support the view that the pain management field may benefit from evolving toward incorporating a less control-oriented and more accommodating view of aversive private experiences in some circumstances.

Previous research supports the fear-avoidance model in explaining chronic low back pain (LBP) disability. The aims of the present study were to determine: (1) whether fear-avoidance model variables are associated already during acute stages of LBP and (2) whether (increases in) pain-related fear are associated with other patient characteristics routinely assessed by the General Practitioner (GP). General practice patients consulting because of a new episode of LBP completed questionnaires on pain-related fear, avoidance, pain and disability. ⋯ Pain-related fear was slightly higher in patients reporting low job satisfaction and in those taking bedrest. These results suggest that the fear-avoidance model as it was developed and tested in chronic LBP, might not entirely apply to acute LBP patients. Future research should focus on the transition from acute to chronic LBP and the shifts that take place between fear-avoidance model associations.

Are migraineurs hypersensitive? A test of the stimulus processing disorder hypothesis.
The concept of hypersensitivity in migraineurs was advanced mainly on the basis of studies on information processing in which increased amplitudes and reduced habituation in cortical evoked and event related potentials were found in migraine sufferers. The present investigation examined whether migraineurs exhibit hypersensitivity within three different experimental paradigms and various non electrocortical response parameters. Samples of 24 migraine, 19 tension-type headache sufferers, and 24 normal controls were compared regarding their subjective estimation of intensity and discomfort due to visual and acoustical stimuli. ⋯ The series of experiments was conducted a second time with half of the participants in order to replicate the findings. The conclusions remained the same. The results of earlier studies on cortical processing can not be interpreted as demonstrating general hypersensitivity in the sense of a dispositional trait in migraine afflicted individuals irrespective of the involved response system.

Several studies have reported that musculoskeletal disorders of the stomatognathic system, commonly known as temporomandibular disorders (TMD) resemble musculoskeletal disorders and chronic pain disorders in general. There is also general consensus that combined biomedical and biopsychosocial methods best support the assessment and management of the cardinal features of TMD, i.e., pain and dysfunction or physical (peripheral) and psychosocial (central) factors. ⋯ The conceptual theories outlined in this review include biomedical models related to temporomandibular joints, muscles of mastication and occlusal factors, psychological models and the biopsychosocial models. An integrated and multidimensional approach concerning physical and psychosocial factors in temporomandibular pain and dysfunction is presented as an example of how the biopsychosocial model and information processing theory may apply in the conceptualization and management of TMD for various health care professionals.
