A challenge in understanding chronic musculoskeletal pain is that research is often siloed between neuroscience, physical therapy/rehabilitation, orthopedics, and rheumatology which focus respectively on 1) neurally mediated effects on pain processes, 2) behavior and muscle activity, 3) tissue structure, and 4) inflammatory processes. Although these disciplines individually study important aspects of pain, there is a need for more cross-disciplinary research that can bridge between them. Identifying the gaps in knowledge is important to understand the whole body, especially at the interfaces between the silos-between brain function and behavior, between behavior and tissue structure, between musculoskeletal and immune systems, and between peripheral tissues and the nervous system. ⋯ PERSPECTIVE: Research on chronic musculoskeletal pain is limited by significant knowledge gaps. To be fully integrated, musculoskeletal pain research will need to bridge across tissues, anatomical areas, and body systems. Research on mind and body approaches encourages a "whole person" approach to better understand musculoskeletal pain.

Pain neuroscience education (PNE) is an approach used in the management of chronic musculoskeletal pain. Previous reviews on PNE and other pain interventions, have focused on mean treatment effects, but in the context of "precision medicine," any inter-individual differences in treatment response are also important to quantify. If inter-individual differences are present, and predictors identified, PNE could be tailored to certain people for optimizing effectiveness. ⋯ PERSPECTIVE: We bring a novel method to pain science for calculating inter-individual differences in response to a treatment. This is conductedwithin the context of a systematic review and meta-analysis on PNE. We highlight how using erroneous methods for calculating inter-individual differences can drastically change conclusions when compared to appropriate methods.

The goal of the current study was to enhance the measurement of the pediatric chronic pain experience through a methodologically rigorous approach. This paper outlines the development and initial validation of a pain intensity measure for pediatric patients with chronic pain using Patient-Reported Outcomes Measurement Information System methodology. Measure development incorporated feedback from children with painful conditions. ⋯ PERSPECTIVE: We have developed and evaluated a clinically sensitive and psychometrically precise 3-item pain intensity measure with Likert-type responses for self-report use among children and adolescents ages 8 to 18 years with chronic pain. Development of the item content and response options included input from children and adolescents with chronic pain. The development of pain intensity items with pediatric appropriate language, and labeled, fewer response options to yield maximal clinically meaningful information improves the precision of pain intensity measurement in children.

During pain, motor performance tends to decline. However, athletes who engage in contact sports are able to maintain performance despite the inherent pain that accompanies participation. This may be the result of being challenged rather than threatened by pain; adaptive coping strategies; habituation to pain; or finding pain less bothersome. ⋯ Moreover, pain tolerance, intensity, and bothersomeness may differentiate novice and experienced athletes. PERSPECTIVE: Exposure to voluntary pain and challenge states are associated with adaptive responses to pain. Motor task performance may be maintained in individuals with more experience of sports-related pain.

Comparative Study
En pointe: dancers report their pain less variably than do controls.
The subjective nature of pain and the lack of a gold standard for objective measurement hinders effective assessment, diagnosis, and treatment. Some individuals, such as professional dancers, are better in assessing and reporting bodily sensations. This observational study aimed to assess whether dancers report their pain less variably, than other people do. ⋯ Multidimensional Assessment of Interoceptive Awareness subscores correlated with pain reporting variability: R2 and ICC with emotional awareness (r = .260, P = .040, and r = .274, P = .030, respectively), and R2 with trusting [r = .254, P = .044]). PERSPECTIVE: The difference between dancers and controls in the magnitude of variability of pain reports is probably due to the dancers' extensive training, which focuses on attention to body signals. Our results suggest that training can improve subjective pain reports, which are essential for quality clinical care.
