Negative attitudes/beliefs surrounding osteoarthritis, pain, and activity contribute to reduced physical activity in people with knee osteoarthritis (KOA). These attitudes/beliefs are assessed using self-report questionnaires, relying on information one is consciously aware of and willing to disclose. Automatic (ie, implicit) assessment of attitudes does not rely on conscious reflection and may identify features unique from self-report. ⋯ Correlations between implicit and self-reported measures were nonsignificant or weak (rho = -0.29 to 0.19, P < 0.001 to P = 0.767). People with painful KOA hold heightened implicit threat-activity associations, capturing information unique to that from self-report questionnaires. Evaluating links between implicit threat-activity associations and real-world behaviour, including physical activity levels, is warranted.

Lumbar medial branch radiofrequency neurotomy (RFN), a common treatment for chronic low back pain due to facet joint osteoarthritis (FJOA), may amplify paraspinal muscle atrophy due to denervation. This study aimed to investigate the asymmetry of paraspinal muscle morphology change in patients undergoing unilateral lumbar medial branch RFN. Data from patients who underwent RFN between March 2016 and October 2021 were retrospectively analyzed. ⋯ The RFN side had a higher increase in multifidus muscle atrophy compared with the contralateral side. The absence of significant preinterventional degenerative asymmetry and the specificity of the effect to the multifidus muscle suggest a link to RFN. These findings highlight the importance of considering the long-term effects of lumbar medial branch RFN on paraspinal muscle health.

Research has consistently suggested that media consumption plays a vital role in children's socialization, including the socialization of painful experiences. Past research examining young children's popular media revealed worrisome trends in media depictions of pain; it consisted of narrow depictions of pain, gender stereotypes, and an overwhelming lack of empathy from observers, which could contribute to pain-related stigma. Research has not yet examined how pain is portrayed in adolescent media, despite adolescence being the developmental period when chronic pain often emerges. ⋯ Furthermore, regardless of observed gender or "race," observers displayed a lack of empathy for sufferers and rarely engaged in prosocial behaviors. Popular media may serve as an agent of socialization in adolescence; thus, pain depictions may be a powerful force in propagating pain-related stigma and inequities. An opportunity exists to harness popular media to adaptively and accurately portray pain to adolescents.
