Viewed through a contemporary medical lens, these features correspond closely to the cumulative consequences of chronic exposure to blunt-force trauma. This article examines the sculpture at the intersection of medicine, neuroscience, and anthropology. The visible injuries represented by the artist evoke conditions that remain familiar to modern clinicians caring for athletes involved in combat sports. Beyond the external signs of trauma, the work also invites reflection on the invisible neurological consequences of repetitive head impacts, including chronic traumatic encephalopathy and other long-term sequelae of brain injury. The sculpture serves as a starting point for a broader discussion of regulated violence as a recurring feature of human societies. From ancient boxing and gladiatorial combat to contemporary boxing and mixed martial arts, organized forms of violence have persisted despite increasing awareness of their biological costs. The Boxer at Rest thus emerges not only as an artistic masterpiece but also as a clinical document and an ethical prompt, illustrating the enduring tension between admiration for human resilience and recognition of the physical and neurological damage incurred in its pursuit.</p>","PeriodicalId":9082,"journal":{"name":"Brain injury","volume":" ","pages":"1015-1017"},"PeriodicalIF":1.5,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148389736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
