Individuals with chronic pain conditions often report movement as exacerbating pain. An increasing number of researchers and clinicians have recognized the importance of measuring and distinguishing between movement-evoked pain (MEP) and pain at rest as an outcome. This scoping review maps the literature and describes MEP measurement techniques. ⋯ These results have clinically significant and research implications. To advance the study of MEP, we offer that consistent terminology, standardized measurement (appropriate for pain type/population), and clear methodological processes be provided in research publications. On the basis of the findings, we have put forth a preliminary definition of MEP that may benefit from the continued scholarly dialog.

Evidence suggests that patients' expectations predict chronic pain treatment outcomes. Although patients vary in terms of expected pain relief, little is known about individual factors related to such variations. This study aims to investigate how patients with various levels of pain relief expectations differ on the basis of biopsychosocial baseline characteristics in the context of multidisciplinary chronic pain treatment. ⋯ Identifying characteristics related to different levels of pain relief expectations is a fundamental step in generating a more comprehensive understanding of how expectations can be of use in the successful management of chronic pain conditions.

Randomized Controlled Trial
Investigating the Effects of Cuing Medication Availability on Patient-controlled Analgesia Pump Usage in Pediatric Patients: Results of a Randomized Controlled Trial.
The study of patient-controlled analgesia (PCA) behaviors has led to a greater understanding of factors that affect the pain experience. Although PCA behaviors can be influenced by cues to medication availability, no studies have examined the effects of such cues in pediatric populations. ⋯ The overall pattern of results suggests that patients in the light group used their PCA in response to the light more than in response to their pain, which likely reflects operant influences on PCA behavior by pediatric patients.
