According to the cognitive-behavioral model of chronic pain, patient beliefs about their chronic pain influence their behavioral and psychological functioning. Previous correlational and longitudinal studies have supported this hypothesis. However, since previous research has relied almost exclusively on patient self-report to assess both beliefs and functioning, shared method variance may explain some of the relationships found. ⋯ Measures of patient beliefs were more strongly associated with self-report measures of pain behaviors and functioning than with spouse and observer ratings of patient pain behaviors. However, significant associations between patient beliefs and both spouse- and observer-reported frequency of patient pain behaviors were found. These findings argue for the generalizability of the relationship found between patient beliefs and patient behaviors across assessment domains, and for the continued application of the cognitive-behavioral model to the understanding of patient adjustment to chronic pain.

The purpose of this study was to determine which specific attributes of painful orofacial symptoms serve as predictors of health care utilization in a population based sample of elderly subjects. Furthermore, we documented patterns of health care utilization selection by type of health care provider. To our knowledge, these specific utilization patterns have never before been reported in the pain literature. ⋯ The overall number of visits was not predicted by pain intensity but by other qualities more associated with time or level of dysfunction caused by the symptom. We also found that elderly adults, typically seek care for toothache from a dentist and from physicians for painful orofacial symptoms not associated with the teeth or mouth. These decisions regarding the selection of a health care professional may, in part, be a function of financial and insurance considerations, anatomical site and perception of the role of dentistry in orofacial care.

Although it is well known that cannabinoids produce antinociception in acute pain models, there is less information on the ability of cannabinoids to alleviate hyperalgesia. In the present study, we determined whether cannabinoids attenuated the development of hyperalgesia produced by intraplantar injection of capsaicin in rats. In normal, untreated animals, intraplantar injection of 10 microg capsaicin produces nocifensive behavior (elevation of the injected paw) suggestive of pain, an increase in the frequency of withdrawal from punctate mechanical stimuli applied to the paw (mechanical hyperalgesia) and a decrease in the latency of withdrawal from noxious heat (heat hyperalgesia). ⋯ Furthermore, these doses of WIN 55,212-2 had no effect on basal withdrawal responses to heat in animals that did not receive capsaicin. The inactive enantiomer WIN 55,212-3 did not alter the development of capsaicin-evoked pain or hyperalgesia. These data suggest that low doses of cannabinoids, which do not produce analgesia or impair motor function, attenuate chemogenic pain and possess antihyperalgesic properties.

Randomized Controlled Trial Comparative Study Clinical Trial
Spinal manipulative therapy versus a low force mimic maneuver for women with primary dysmenorrhea: a randomized, observer-blinded, clinical trial.
Non-drug therapies for women with primary dysmenorrhea are primarily based on anecdotal evidence and small-scale clinical studies. This randomized, observer-blinded, clinical trial evaluated the efficacy of spinal manipulative therapy (SMT) in the treatment of women with primary dysmenorrhea. Women were recruited from the Chicago metropolitan area and evaluated for inclusion through four screening levels. ⋯ The LFM maneuver used in this study was designed to act as a 'placebo-like' control treatment in comparison with SMT. Although it is possible that the trial did not continue long enough for any placebo effect of the LFM to wash out, it seems more likely that this maneuver was indistinguishable from SMT. Therefore, the postulated superior benefit of high-velocity, short-lever, low-amplitude, high-force spinal manipulation to a low-force maneuver is not supported by the results of this study. 1999 International Association for the Study of Pain.

Randomized Controlled Trial Clinical Trial
Relief of postoperative pain with jaw relaxation, music and their combination.
The aim of this randomized controlled trial was to determine the effect of jaw relaxation, music and the combination of relaxation and music on postoperative pain after major abdominal surgery during ambulation and rest on postoperative days 1 and 2. Opioid medication provided for pain, following abdominal surgery, does not always give sufficient relief and can cause undesired side effects. Thus, additional interventions such as music and relaxation may provide more complete relief. ⋯ At post ambulation those using relaxation did not have significantly less pain than the controls on both days and those using music did not on day 1, although there were some univariate effects. A corresponding significant decrease in mastery of the interventions from pre to post ambulation suggests the need for reminders to focus on the intervention during this increased activity. Physicians and nurses preparing patients for surgery and caring for them afterward, should encourage patients to use relaxation and music as adjuvants to medication for postoperative pain.
