The present study observes a military sample across race to better understand suicide risk among American Indian/Alaska Native (AI/AN) individuals utilizing the Interpersonal Theory of Suicide. In a sample of 3,387 Army recruiters, multivariate analysis of variance was used to compare the means across race on acquired capability and pain tolerance. AI/AN individuals demonstrated higher levels o...

Pain magnitude and pain tolerance for arm immersion in ice water were assessed during a baseline and posttest session. Before the posttest half the subjects received (and half did not receive) an analgesia suggestion. On the basis of their written testimony, subjects were classified as having either predominantly coped (e.g., imagined events inconsistent with pain; made positive self-statements...

Aim. Poor sleep quality due to pain has been reported among opioid-dependent male patients on methadone maintenance therapy (MMT) but objective pain data are lacking. This study aimed to investigate the rate of pain-sensitivity using cold pressor test (CPT) and the relationship between pain-sensitivity and sleep quality in this population. Methods. A total of 168 male participants were included...

OBJECTIVE Among rheumatoid arthritis (RA) patients, the intensity of pain may be out of proportion to the severity of peripheral inflammation. This observation suggests that mechanisms of central nervous system pain amplification, such as diminished conditioned pain modulation (CPM), may play a role in enhancing pain perception among some RA patients. This study was undertaken to examine the le...

Forty subjects served in a study investigating the characteristics of experimental pain measures. Subjects indicated when their pain threshold and tolerance levels had been reached with each of three stressors: cold, pressure, and electrical shock. Using the multitrait-multimethod matrix procedure, the measures of threshold and tolerance were found to show both generality and discriminant valid...

Pain in any context is always associated with high interand intra-individual variability. There are several paininducement methods and numerous pain measurement methods at researchers’ disposal in experimental settings; since none of them is without limitations, the increasing number of researchers decides upon a multimethod approach. In doing so, clarity and unambiguity of the results may vary...

Opioids, the wonderful analgesics, remain the mainstay in the clinical management of moderate to severe pain. However, development of analgesic tolerance and increase in pain sensitivity are some of the major concerns following opioid treatment. Studies suggest that NMDA receptor-mediated intracellular events play a role in mediating these effects. Moreover, NMDA receptor antagonists effectivel...

The current study examines how subjective pain reporting is influenced by the concordant and discordant nature of the ethnic identities of pain expressers (participants) and pain assessors (experimenters). Three discomfort conditions that varied in stimuli intensity (Study 1: mild pain; Study 2: severe pain), and distraction components (Study 3) were used to assess whether pain intensity and to...

ABSTRACT While muscle stretching has been commonly used to alleviate pain, reports of its effectiveness are conflicting. The objective this review is investigate the acute and chronic effects on including delayed onset soreness. few studies implementing protocols have reported small large magnitude decreases in quadriceps anterior knee pain as well reductions headache pain. Chronic programs dem...

The effect of NMDA (N-methyl-D-aspartate) receptor antagonists on tolerance to morphine antinociception was investigated in mice. Daily subcutaneous administration of 50 mg/kg of morphine hydrochloride for three days induced tolerance to different (3,6 and 9 mg/kg) test doses of morphine. The tolerance obtained was decreased by pretreatment of animals with single or repeated doses of compe...
