Black communities are disproportionally affected by Chronic Musculoskeletal Pain (CMP), but little is known about the psychological predictors of CMP outcomes and their contextual determinants among Black individuals. To address this gap, we conducted a narrative review of extant literature to (1) report the major conceptual models mentioned in prior work explaining the link between contextual determinants and psychological responses to pain among Black individuals with CMP; and (2) describe psychological factors related to CMP outcomes in this population that are highlighted in the literature. ⋯ PERSPECTIVE: This narrative review illustrates conceptual models explaining the link between contextual determinants and psychological responses to pain among Black individuals with chronic musculoskeletal pain. We discuss 3 relevant conceptual models - socioecological, cumulative stress, biopsychosocial -, and 4 psychological factors: disproportionate burden of mental health, distinct coping strategies, perceived injustice/discrimination, preferences/expectations.

Review Meta Analysis
The Effect of Acute and Sustained Pain on Corticomotor Excitability: A Systematic Review and Meta-analysis of group- and individual-level data.
Pain alters motor function. This is supported by studies showing reduced corticomotor excitability in response to experimental pain lasting <90 minutes. Whether similar reductions in corticomotor excitability are present with pain of longer durations or whether alterations in corticomotor excitability are associated with pain severity is unknown. ⋯ In otherwise healthy individuals, suppression of corticomotor excitability may be a beneficial short-term strategy with long-term consequences. PERSPECTIVE: This systematic review synthesised the evidence for altered corticomotor excitability in response to experimentally induced pain. Reduced corticomotor excitability was associated with lower acute pain severity but higher sustained pain severity, suggesting suppression of corticomotor excitability may be a beneficial short-term adaptation with long-term consequences.
