Investigating Physical Activity and Its Association to Activities of Daily Living in People with Lower Limb Amputation: A Mediating Role of Independence Level

Background and Objectives: Lower limb amputation can significantly affect levels of physical activity and ability to engage in daily sports, often affecting independence. Accordingly, this study investigates the association between physical activity and activities of daily living in humans with lower limb amputation, focusing on the mediating role of level of independence. Methods: This cross-sectional study was conducted at the Babylon Rehabilitation Center between August and November ۲۰۲۴. A total of ۲۴۶ samples were collected using purposive non-probability sampling. The data were collected using validated instruments: the international physical activity questionnaire, the Nottingham scale of daily activities, and the Barthel independence index. A data series, including structured interviews, was conducted and analyzed using the Pearson correlation and linear regression in the SPSS software, version ۲۰.۰. Results: A total of ۷۵.۶% of the members had low levels of physical activity, ۶۸.۷% had low activities of daily living, and ۷۷.۶% were unable to complete daily tasks. A high-quality relationship was observed between physical activity and daily life (P = ۰.۰۰۰). Simple linear regression revealed that independence levels predicted physical activity (P = ۰.۰۰۰) and activities of daily living (P = ۰.۰۰۰). Conclusion: The study highlights the importance of promoting independence as a pathway to improving physical activity levels and functional independence in activities of daily living.
