After whiplash injury, some patients develop chronic whiplash-associated disorders. The exact pathophysiology of this chronification is still unclear and more knowledge is needed regarding the different post-injury phases. Therefore, studies were searched that examined temporal changes in pain processing, measured by Quantitative Sensory Testing (QST). ⋯ Altered pain processing is present soon after whiplash injury, but usually recovers within 3 months. Non-recovering patients show little to no improvements in the following years. Differences between recovering and non-recovering patients can be observed by Quantitative Sensory Testing already in the acute phase. Therefore, it is considered a feasible and effective tool that can contribute to the identification of high-risk patients and the prevention of chronification.

Women with Vulvodynia experience pain, related impacts on sex and daily functioning, and depression. While psychosocial factors are associated with outcomes in Vulvodynia, longitudinal data are limited, especially in mixed/spontaneous Vulvodynia. Broad psychological models such as psychological flexibility (PF) and content-specific factors, such as body-exposure anxiety (BEA) and avoidance during sexual activities and perceived injustice, have not been adequately investigated in Vulvodynia. The aim of this study was to explore whether these factors assessed at baseline predict pain severity, pain interference, sexual functioning and satisfaction and depression 3 months later. ⋯ This longitudinal study explored the role of PF, perceived injustice and body image during sexual activities in predicting pain severity, pain interference, sexual functioning, sexual satisfaction and depression in women with Vulvodynia. The study findings reveal that two facets of PF (committed action and pain acceptance) predicted pain interference and depression over time. It may be important to incorporate these processes in treatments developed for Vulvodynia.

Studies examining the effect of biased cognitions on later pain outcomes have primarily focused on attentional biases, leaving the role of interpretation biases largely unexplored. Also, few studies have examined pain-related cognitive biases in elderly persons. The current study aims to fill these research gaps. ⋯ Adults with chronic pain endorsed more injury-/illness-related interpretations than pain-free controls. Older adults endorsed more illness interpretations than younger adults. A more negative interpretation bias indirectly predicted pain disability 6 months later through hypervigilance towards pain.
