Observational Study
Sociodemographic disparities and potential biases in persistent pain estimates: Findings from 5 waves of the Irish Longitudinal Study on Ageing (TILDA).
Pain is a prevalent, debilitating condition among older adults. Much evidence on this topic comes from cohort studies, which may be affected by attrition and measurement bias. Little is known about the impact of these biases on pain estimates for European older adults. Additionally, there is a lack of longitudinal research on pain and sociodemographic disparities in Irish older adults. ⋯ This study highlights a need to address bias in the estimation of pain in observational studies of older adults. Understanding the sources and extent of these biases is important so that health practices and policies to address pain disparities can be guided by accurate estimates. Women, those with lower educational attainment, and those without private health insurance were found to have the highest pain burden longitudinally, suggesting a need for targeted interventions for these groups in Ireland and internationally.

Chronic pain (CP) can be a disabling condition with impacts that affect the sense of identity of those who live with it. This article idiographically describes the longitudinal evolution of the sense of self of participants following their referral to a pain management service and participation in a pain management programme (PMP). ⋯ Not enough is understood about why some people get limited benefits from pain services. This idiographic longitudinal study illustrates how the impact of CP on identity can evolve when people are introduced to pain self-management, with some embracing change and others resisting it. For clinicians, this study describes four detailed CP individual paths, showing the interaction between contextual and idiosyncratic aspects. This is also the first study to use multiple drawings of self to explore the impacts of illness on identity longitudinally. In a person-centred approach to treatment, the drawings of self could also be adopted as a tool in clinician-patient conversations to gain a deeper understanding of the impacts of living with CP.

Balance alterations are prevalent among pain conditions, including migraine. The mechanisms explaining the association between pain and balance are unclear, as well as whether levels of pain sensitivity correlate with impaired balance. Our aim was therefore to investigate the association between balance, central sensitization symptoms and pain sensitivity in patients with migraine. ⋯ For the first time, it has been shown that balance alterations can reflect greater pain sensitivity and signs of central sensitization in patients with migraine. This opens up perspectives for future studies to understand the mechanisms and further factors associated with balance and pain sensitivity in migraine.

Autonomic nervous system dysfunction has been reported to be associated with impaired activities of daily living (ADL) among patients with chronic pain, but the association has not been fully addressed in general populations. This study cross-sectionally investigated the association between autonomic nervous system function and the presence of subjective symptoms affecting ADL in community-dwelling residents with chronic pain. ⋯ Decrease in heart rate variability was associated with the presence of symptoms affecting ADL among individuals with chronic pain in a Japanese community. This article could help scientists understand the significance of autonomic nervous system dysfunction in the pathology of chronic pain. Approaches that target autonomic nervous system dysfunction may be an option to relieve or prevent symptoms affecting ADL for chronic pain sufferers.
