Comparative StudyEthnic Differences Identified by Pain Sensitivity Questionnaire Correlate With Clinical Pain Responses.
The Pain Sensitivity Questionnaire, English version (PSQ-E), is predictive of pain-related responses to experimental stimuli. Ethnic differences have been noted in experimental measures of pain sensation using quantitative sensory testing. The present study sought to determine if the PSQ-E also identified similar ethnic differences. ⋯ The study demonstrated significantly elevated pain sensitivity in AA compared with NHW patients as measured by the PSQ-E and experimental and clinical pain intensity scores. This shows that the PSQ reflects the known elevation of pain sensitivity in AA subjects and suggests that it may be useful in assessing pain treatment disparities by identifying and standardizing differences in pain sensitivity.

Multicenter Study
Reliability Study in Five Languages of the Translation of the Pain Observational Scale Algoplus.
Acute pain is frequent and underestimated in older persons, especially when they suffer from cognitive impairment. Algoplus is an observational scale for acute pain evaluation, validated in French in older persons with communication disorders. We present the validation by an international expert team of the Algoplus scale in five languages: English, Spanish, Italian, Portuguese, and Turkish. ⋯ This study shows evidence that Algoplus is an acceptable, reproducible, reliable, and easy-to-use tool. It provides a unique opportunity to include the translated Algoplus scale in daily assessment of older persons with communication disorders in many countries.

Observational StudyValidation of two Chinese-version pain observation tools in conscious and unconscious critically ill patients.
To compare the construct validities of the Chinese-versions Critical-Care Pain Observation Tool and Behavioural Pain Scale as measures of critically ill patients' pain by (a) discriminant validation of behavioural scales and vital signs (e.g. heart rate and mean arterial pressure) during a non-nociceptive procedure (noninvasive blood pressure] assessment) and a nociceptive procedure (endotracheal suctioning), (b) criterion validation of behavioural scales and vital signs with patients' self-reported pain and (c) testing the interrater reliability of both scores. ⋯ The Chinese-versions of the Critical care Pain Observation Toll and Behavioural Pain Score have good construct validity and can sensitively discriminate when critically ill patients experience pain or no pain.

The Critical care Pain Observation Tool is reliable in non-agitated but not in agitated intubated patients.
The Critical-Care Pain. ⋯ Discriminant and criterion validity, confirmatory factor analysis and internal reliability showed good validity and reliability in the critical care pain observation tool in all groups except agitated patients. The results showed that, in general, the CPOT has good version of the critical care pain observation tool has good psychometric properties to evaluate pain in non-verbal patients admitted to intensive care units who have a RASS score ranging from -3 to +1, but it is not a good tool to evaluate pain in patients who are agitated according to RASS.

The Relationship Between Rate of Algometer Application and Pain Pressure Threshold in the Assessment of Myofascial Trigger Point Sensitivity.
Pressure algometry is a commonly employed technique in the assessment of both regional and widespread musculoskeletal pain. Despite its acceptance amongst clinicians and scientists, the relationship between rate of pressure application (RoA) and pain pressure threshold (PPT) remains poorly understood. We set out to test the hypothesis that a strong, positive, linear relationship exists between the RoA and the PPT within the infraspinatus of young healthy subjects. ⋯ Our results demonstrate that there is a strong, linear relationship between the RoA and PPT when using the pressure algometry technique. The low slope between RoA and PPT suggests clinicians can rely on PPT assessments despite small RoA fluctuations. Future research should explore this relationship further in a clinical population and in other muscles affected by chronic myofascial pain. Advancing cost-effective, reliable, and clinically feasible tools such as algometry is important to enhancing the diagnosis and management of chronic myofascial pain.
