Pressure pain thresholds in patients with chronic nonspecific low back pain.
The lumbar back and hip muscles are important for a normal functioning of the human spine and they are considered to be of etiological significance in chronic nonspecific low back pain (nCLBP). Inactivity and a lower level of physical activity in patients with nCLBP may change muscle characteristics and may be associated with pain and disability. Pressure algometry has been found to be non-invasive, efficient and reliable in the exploration of physio-pathological mechanisms involved in muscle pain syndromes. The subjective characteristic of the pressure pain thresholds (PPTs) cannot be avoided once it is the very objective of the measurement, i.e. the minimum pain perceptible by the person, is a subjective factor. Most studies have revealed gender differences between PPTs, with females showing lower thresholds. ⋯ This study showed that most PPT values are correlated to the VAS and the RM. Nevertheless, the variability explained by PPT values and demographic characteristics was low for pain intensity and function.

Multicenter Study
Restricted activity and persistent pain following motor vehicle collision among older adults: a multicenter prospective cohort study.
Restricted physical activity commonly occurs following acute musculoskeletal pain in older adults and may influence long-term outcomes. We sought to examine the relationship between restricted physical activity after motor vehicle collision (MVC) and the development of persistent pain. ⋯ Among older adults experiencing MVC, those reporting bed rest or reduced activity 6 weeks after the collision reported higher pain and pain interference scores at 6 months. More research is needed to determine if interventions to promote activity can improve outcomes after MVC in older adults.

Clinical TrialRacial bias in pain assessment and treatment recommendations, and false beliefs about biological differences between blacks and whites.
Black Americans are systematically undertreated for pain relative to white Americans. We examine whether this racial bias is related to false beliefs about biological differences between blacks and whites (e.g., "black people's skin is thicker than white people's skin"). Study 1 documented these beliefs among white laypersons and revealed that participants who more strongly endorsed false beliefs about biological differences reported lower pain ratings for a black (vs. white) target. ⋯ Moreover, participants who endorsed these beliefs rated the black (vs. white) patient's pain as lower and made less accurate treatment recommendations. Participants who did not endorse these beliefs rated the black (vs. white) patient's pain as higher, but showed no bias in treatment recommendations. These findings suggest that individuals with at least some medical training hold and may use false beliefs about biological differences between blacks and whites to inform medical judgments, which may contribute to racial disparities in pain assessment and treatment.

[Evaluation of physical function for the end-stage osteoarthritis patient waiting for the total knee replacement].
To collect comprehensive data of the physical function of the end-stage osteoarthritis (OA) patients, and compare it with patients with mild OA. To evaluate the correlations among pain, self-reported questionnaire, performance based physical function and actual daily life activity level. ⋯ The usage of lots of different physical parameters from Chinese OA patients were reported in this study. The results showed that there are no good correlations among performance based physical function test, actual daily activity level, self reported questionnaires, and the pain scales. More comprehensive evaluation for the OA patients needs to be made, in order to make better decision for arthroplasty.
