Strength training in addition to neuromuscular exercise and education in individuals with knee osteoarthritis the effects on pain and sensitization.
There is a lack of evidence of the relative effects of different exercise modes on pain sensitization and pain intensity in individuals with knee osteoarthritis (KOA). ⋯ This study is an important step towards better understanding the effects of exercise in pain management of chronic musculoskeletal conditions. We found that strength training in addition to neuromuscular exercise and education compared with neuromuscular exercise and education only had a differential impact on pain sensitization and pain intensity, but also that regardless of the exercise mode, the positive effects on pain sensitization and pain intensity were comparable to the effects of other therapeutic interventions for individuals with knee osteoarthritis.

Primary dysmenorrhoea (PDM) is known to alter brain static functional activity. This study aimed to explore the dynamic topological properties (DTP) of dynamic brain functional network in women with PDM in the pain-free phase and their performance in distinguishing PDM in the pain-free phase from healthy controls. ⋯ This study shows that women with primary dysmenorrhoea (PDM) have decreased stability of dynamic network topological properties (DTP) and increased DTP variability in the pain-free phase. The altered DTP can be used to identify PDM in the pain-free phase. These findings demonstrate the presence of unstable characteristics in the whole network and disrupted pain-related neurocircuits, which might be used as potential classifiers for PDM in the pain-free phase. This study improves our knowledge of the brain mechanisms underlying PDM.

Pain assessment and pain care are influenced by the characteristics of both the patient and the caregiver. Some studies suggest that the pain of older persons and of females may be underestimated to a greater extent than the pain of younger and male individuals. ⋯ The characteristics of the patients seem to have a greater impact on prosocial behavior and pain assessment compared to those of the observers, which bears significant implications for the treatment of pain in clinical contexts.

The mediating effect of pain catastrophizing on pain intensity: the influence of the timing of assessments.
Pain catastrophizing underpins several psychosocial theories of pain, but there is limited evidence to support the proposal that changes in pain catastrophizing cause changes in pain. Results from mediation analyses have conflicting results, and one reason for these might be the timing of the assessment of pain catastrophizing. This study aimed to test the effect of the timing of the assessment of pain catastrophizing on its mediating role on pain intensity. ⋯ The timing of the assessment influenced the mediating role of pain catastrophizing on pain intensity. These results raise questions on the casual role that pain catastrophizing has on pain intensity. Psychosocial interventions such as clinical hypnosis can reduce pain intensity even when there has been no change in pain catastrophizing.

Chronic pain is a major healthcare issue that often requires an interdisciplinary treatment approach. Defining relevant treatment goals is one of the crucial steps in creating successful rehabilitation schemes. Therefore, the first aim was to explore goals that patients suffering from chronic pain aim to achieve. The second aim was to translate those goals into measurable functional outcome variables which can be used to measure treatment success. ⋯ Goals and expectations of chronic pain patients are in line with each other. Obtaining pain relief remains the highest ranked goal, however, goals on the level of activities and participation were also highly ranked. Walking seems to be the overall crucial component for goal achievement.
