Background:Older adults with amputations secondary to vascular etiologies may additionally present with cognitive impairment. Cognition plays an important role in the adoption of a prosthetic limb, although the degree and type of impact are debated. Previous literature reviews have not been directed at the specific population of older adults who underwent vascular-related lower limb amputation.Objectives:First, to assess extant literature for relationships between cognitive function and prosthesis-related outcomes in older adults who underwent lower limb amputation for vascular-related etiologies. Second, to perform a critical analysis of prosthesis-related outcomes and cognitive assessments performed in the studies.Study design:Systematic literature review.Methods:A systematic review of the literature was performed in databases using keyword combinations. A total of nine articles were selected to be included in this review.Results:Seven of the nine included studies found a relationship between decreased cognitive function and reduced performance on a prosthesis-related outcome. There were eight different prosthesis-related outcome measures, with only one study utilizing a comprehensive outcome measure.Conclusion:Cognitive impairment can negatively impact successful prosthesis use in older adults with lower limb amputation secondary to vascular complications. Future studies should utilize comprehensive outcome measures that represent the multifaceted constructs of cognition and prosthesis use.Clinical relevanceCognitive assessment of older adults who have undergone lower limb amputation secondary to diabetes related complications or vascular disease can be used to inform clinical decision-making. Clinicians should consider selecting prosthesis-related outcome measures that capture the full breadth of prosthesis use when evaluating patients with cognitive impairment.
