Purpose: Identifying factors associated with physical activity after dysvascular lower limb amputation (LLA) could provide targets for improving rehabilitation outcomes. The purpose of this meta-synthesis was to identify modifiable factors that may influence physical activity after LLA, a condition characterized by amputation in the setting of older age, diabetes mellitus (DM), and/or peripheral artery disease (PAD).Methods: A systematic search of the literature identified qualitative studies exploring the perceptions of physical activity in people with lower limb amputation, older age, DM, or PAD. Qualitative rigor was assessed using the McMaster Universitys Guidelines for Qualitative Review. Meta-synthesis was undertaken to analyze the findings of included studies.Results: Fourteen studies of variable methodological quality were included for analysis. Three overarching factors that may influence physical activity after LLA emerged: 1) educational experiences and motivation, 2) support and self-efficacy, and 3) special concerns after lower limb amputation (e.g., prosthesis, equipment, and environment).Conclusions: Physical activity after LLA is influenced by relationships among health understanding, motivation, support, and self-efficacy in the presence of disability. Themes from this meta-synthesis can be used to develop and test behavior-based interventions to improve physical activity after LLA.Implications for rehabilitationPhysical activity participation after dysvascular lower limb amputation is complicated by the presence of chronic conditions, severe disability, and unaddressed psychosocial factors.Addressing a patients self-efficacy, social support, motivation, and understanding during physically focused rehabilitation may improve participation in physical activity after dysvascular lower limb amputation.Rehabilitation professionals can address self-efficacy, motivation, and understanding by using collaborative, empathetic communication strategies known to enhance a patients sense of support.
