Identifying factors that influence the course of low back pain (LBP) is important to help clinicians to identify those patients at higher risk of non-recovery. The objective of this systematic review was to investigate the prognostic role of physical activity in the course of LBP. ⋯ Despite recent research in the area, this systematic review shows that there is low quality evidence that physical activity may not be a prognostic factor for predicting pain and disability in patients with LBP.

Multidisciplinary pain management (MPM) is a generally accepted method for treating chronic pain, but heterogeneous outcome measures provide only limited conclusions concerning its effectiveness. Therefore, further studies on the effectiveness of MPM are needed to identify subgroups of patients who benefit, or do not benefit, from these interventions. Our aim was to analyse health-related quality of life (HRQoL) changes after MPM and to identify factors associated with treatment outcomes. ⋯ Multidisciplinary pain management (MPM) increases the health-related quality of life (HRQoL) in most patients. More research into factors associated with HRQoL change is needed to understand why not all patients benefit from MPM and how MPM approaches could be improved to meet the needs of these patients.

Low back pain (LBP) is a global public health challenge, which causes high healthcare costs and the highest burden on society in terms of years lived with disability. While patients' expectations for improvement may have effects on LBP treatment outcomes, it remains unclear if psychological profiles modify this relationship. Therefore, the objectives of this study were to investigate if (a) patients' expectations predicted short-term outcome, and (b) psychological profile, pain intensity and self-rated health modified the relationship between expectations and outcome. ⋯ This study confirms the importance of patients' expectations in a clinical setting. Patients' expectations predict the short-term outcome of chiropractic care for LBP. Pain intensity, psychological profile and self-rated health did not modify this relationship.

Splinting is a quite common intervention for the first carpometacarpal (CMC) osteoarthritis, however, underlying mechanisms of biomechanical and analgesic effects has not been fully investigated. The aim of this study was to develop an experimental basal thumb pain model and to elucidate the effects of CMC splinting on the pain profile and motor function. ⋯ Newly developed experimental basal thumb pain model decreased tip pinch strength approximately 50%, concomitant with the reduction of intrinsic muscle activities. Splinting for the first carpometacarpal joint significantly improved experimental pain, loss of pinch strength and inhibited intrinsic muscle activity compared with bare hand.

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.
