The aim of this study was to examine associations between a cognitive
screen and four neuropsychologic tests administered at both 6 wks and 4 mos after
amputation and five functional outcomes measured 12 mos after lower extremity
amputation. DESIGN: This study includes a prospective cohort from four medical
centers. Participants were primarily male Veterans experiencing their first lower
extremity amputation as a result of complications of diabetes mellitus or
peripheral arterial disease. Of those eligible, 87 (64%) enrolled; 75 (86%) were
retained at 12 mos. Measures included demographic/health information, four
neuropsychologic measures, the Locomotor Capability Index-5, the Gronigen
Activity Restriction Scale, prosthetic use, community participation, and social
integration. RESULTS: Better performance on the Short Portable Mental Status
Questionnaire at 4 mos was associated with greater 12-mo mobility and social
integration. Better attention and working memory abilities 6 wks after amputation
were associated with increased 12-mo prosthetic wear; and at 4 mos after
amputation, with greater 12-mo mobility. Better verbal memory at 6 wks was
associated with greater 12-mo social integration and community participation as
well as increased prosthetic wear. CONCLUSIONS: These findings highlight the
potential value in including a brief, formal cognitive assessment in addition to
a general mental status screen. Specific domains of cognitive function are
differentially associated with functional outcomes and may inform amputation
rehabilitation decisions.
