On the body-mind nexus in chronic musculoskeletal pain: A scoping review.

Abstract

Bodily experience disturbances are frequent among chronic musculoskeletal pain patients and associated with important pain-related psychosocial outcomes (e.g., disability, quality of life). However, the relationship between bodily experience and the psychological dimensions of chronic pain (e.g., affective, cognitive) has only recently garnered attention. This scoping review aimed to identify trends and gaps in research on the nexus between body awareness, body image, and body schema, and psychological processes/outcomes in adults with chronic musculoskeletal pain to inform future directions for research and practice. This study was guided by Arksey and O'Malley's guidelines and PRISMA-ScR recommendations. Keywords related to body awareness/body image/body schema and pain were searched on PsycInfo and PubMed from database inception until 16 February 2021; 2045 articles were screened, and 41met the inclusion criteria (i.e., primary quantitative studies investigating body awareness/body image/body schema in relation to pain-related psychological outcomes/processes in chronic musculoskeletal pain). The referred bodily experience constructs have been inconsistently defined. Body awareness was the most investigated construct, with consistent operationalization strategies. The links between body schema/body image and pain-related psychological processes/outcomes are still under-investigated. Most studies examined the role of bodily experience as a correlate/predictor of psychological outcomes/processes; overall, a better relationship with one's own body was associated with better pain-related psychological outcomes/processes. Our findings emphasize the relevance of further investigating body-mind relations in musculoskeletal pain and the development of therapies designed to improve the bodily experience within multidisciplinary treatment programmes. Suggestions for future research are discussed. This scoping review identifies trends/gaps in current research on the relationship between body awareness/body image/body schema and pain-related psychological processes/outcomes in adults with musculoskeletal pain. Overall, findings suggest that better bodily experiences are associated to lower fear-avoidance beliefs, better self-regulation strategies and better chronic pain adjustment, being important targets in pain management interventions. Nonetheless, the results also emphasize the need to further investigate the causal relationships and other outcomes related to psychological resilience, as well as to develop gold standard treatments focused on bodily experience.
