Objective To analyze and elucidate the definition and conceptual dimensions of life space in stroke patients, so as to provide references for healthcare professionals to assess patients′ life space and develop nursing interventions. Methods We systematically searched databases including CNKI, Wanfang Data, VIP, SinoMed, PubMed, Web of Science, Embase, and the Cochrane Library from their inception until July 2025. Literature was screened according to predefined inclusion and exclusion criteria. Rodgers′ evolutionary concept analysis methodology was employed for conceptual analysis and definition. Results A total of 39 articles were included. The life space in stroke patients could be classified into 5 key attributes:spatial hierarchy, activity frequency, activity autonomy, activity functionality, and environmental interaction. Antecedents included demographic factors, dimensions of health status, psychological status, and external support systems. Consequences comprised the reinforcement of physical function, optimization of quality of life, regulation of healthcare burden, and promotion of social integration. Conclusion This concept analysis clarifies the defining characteristics of life space in stroke patients. Based on this conceptual framework, researchers can develop specific assessment tools and design staged, multi-context intervention plans. These initiatives ultimately aim to expand patients′ life space, thereby promoting functional recovery and enhancing the quality of their social participation.
