Observational Study
Exercise-induced hypoalgesia is present in people with Parkinson's disease: Two observational cross-sectional studies.
Exercise is prescribed for people with Parkinson's disease to address motor and non-motor impairments, including pain. Exercise-induced hypoalgesia (i.e., an immediate reduction in pain sensitivity following exercise) is reported in the general population; however, the immediate response of pain sensitivity to exercise in people with Parkinson's disease is unknown. The purpose of this study was to investigate if exercise-induced hypoalgesia is present following isometric and aerobic exercise in people with Parkinson's disease, and if so, if it varies with the dose of aerobic exercise. ⋯ Isometric and aerobic exercise reduces pain sensitivity in people with Parkinson's disease. As exercise is important for people with Parkinson's disease, these results provide assurance that people with Parkinson's disease and pain can exercise without an immediate increase in pain sensitivity. The reduction in pain sensitivity with both modes and with low and moderate intensities of aerobic exercise suggests that people with Parkinson's disease can safely choose the mode and intensity of exercise that best suits their needs.

There is currently a knowledge gap regarding persistent opioid use after hip fracture surgery. Thus, opioid use within a year after hip fracture surgery in patients with/without opioid use before surgery was examined. ⋯ Opioid use 1 year after hip fracture surgery is common, both in patients who were opioid users and nonusers before the surgery. These significant findings point out the need for indication of benefits and risks of opioid use in the acute and long-term management of patients undergoing hip fracture surgery.

The parent's role in the context of pediatric chronic pain is essential. There is growing evidence that parent psychological flexibility positively impacts child functioning. To assess parents' abilities to respond with psychological flexibility to their child's pain, the Parent Psychological Flexibility Questionnaire (PPFQ) was developed. Here, we aim to validate the 10-item version of the questionnaire in an English-speaking population and to evaluate associations with parent behaviour, child pain acceptance and functioning. ⋯ Our findings demonstrate that the PPFQ-10 is an efficient measure of parent psychological flexibility, demonstrating strong psychometric properties. Furthermore, our analyses showed that parent psychological flexibility indirectly affects child functioning through associations with both adaptive parent behaviour and child functioning. Taken together, this study furthers the understanding of how parent psychological flexibility operates and affects children with chronic pain, and may inform and optimize treatments aimed at improving functioning by addressing child and parent coping.

The relationships between worry, happiness and pain catastrophizing in the experience of acute pain.
The current study aimed to (a) evaluate the effects of an experimental manipulation of worry and happiness on pain perception and measures of worry about pain and pain catastrophizing and (b) determine if changes in situation-specific worry about pain and pain catastrophizing would be related to changes in acute pain. ⋯ The current study shows that manipulation-induced changes in pain-related worry, pain catastrophizing, and affect have direct effects on the experience of acute pain. More broadly, the overlap of these three variables provides with anxiety and mood disorders offers the promise of new vistas for research and treatment of pain conditions by assessing and targeting the cognitions and behaviors that are common to worry and catastrophizing.
