| Abstract: | The growing adoption of Digital Twins (DTs) in Industry 4.0 (I4.0) raises the challenge of ensuring model validity throughout the operational lifecycle. Unlike static validation, which is limited to the development phase, continuous validation aims to ensure that the DT remains representative of the physical system during operation. This paper presents a critical review of conceptual and applied approaches to continuous or recurrent DT validation. The studies are classified into continuous monitoring proposals, methods with potential for recurrent adaptation, and conceptually aligned approaches. For each group, methods, results, and limitations are discussed. A comparative analysis reveals relevant gaps, including the lack of formal criteria for selecting critical variables and difficulties in diagnosing the causes of deviations. Finally, emerging trends and future directions are outlined, highlighting the integration of statistical techniques, such as control charts, to enhance the reliability and traceability of DTs in dynamic industrial environments.
