This study investigated how specific expressive behaviors (verbal report of pain level and the frequency of emitting specific non-verbal facial expressions of pain) may change over the course of a chronic pain condition. Based on the concept of chronic pain behaviors, we hypothesized that both verbal and non-verbal behavior would increase with duration of pain. Thirty-six women with chronic temporomandibular disorder (TMD) pain (duration over 6 months) were compared with 35 recent onset cases (first episode, duration < or = 2 months). ⋯ Coping strategies were also similar, although chronic cases showed a greater tendency to catastrophize. Self-report measures of ambient facial pain, as well as the pain of clinical examination and cold pressor stimulation, revealed no significant differences between the 2 groups. In contrast, rates of pain facial expression were significantly higher for chronic cases under all conditions of the experiment, including baseline.(ABSTRACT TRUNCATED AT 250 WORDS)

Pain provocation was analyzed in 1477 intervertebral discs in 523 patients subjected to lumbar computed tomography/discography. The relation between pain provocation and the degree of general degeneration and anular disruption assessed according to the Dallas Discogram Description as indices of intradiscal deterioration was investigated. ⋯ Pain provocation showed little relation to intradiscal deterioration, whereas a strong relation was found between it and herniated nucleus pulposus. in herniated nucleus pulposus, discs with extraligamentous extrusion or sequestration, large protrusions, maximum protrusion site at the nerve root portion, and herniation routes passing through the central portion of the disc showed a high pain provocation ratio. Pain provocation ratios of discs associated with spinal canal stenosis were extremely low.

Comparative StudyComparison of two pain rating scales among Chinese cancer patients.
The Simple Descriptive Scale (SDS) has been known to be easier to use, but lacks sensitivity when compared to the Visual Analogue Scale (VAS). In this study, 79 cancer patients quantified the intensity of their pain experience on both the VAS and SDS before receiving pain therapy and on the fifth day after commencing the therapy. ⋯ The results demonstrate that the SDS provides a simpler and, perhaps, equally sensitive alternative to the VAS, in measurement of cancer pain among Chinese patients. It would be particularly useful for those with language barriers and/or other factors in understanding the requirements or the VAS.

The key to effective pain control is accurate assessment and, more importantly, the belief that what patients state about their pain is true. This research study investigates nurses' attitudes to pain and its assessment, and reveals why pain control continues to be an inconsistent affair.
