OBJECTIVE: To investigate the association between cognitive functioning, as measured by the Montreal Cognitive Assessment (MoCA), and functional outcomes upon discharge from prosthetic rehabilitation.
DESIGN: Retrospective chart audit.
SETTING: Rehabilitation hospital.
PARTICIPANTS: Consecutive admissions (N=130; mean age, 66.21±11.19y) with lower extremity amputation of dysvascular etiology.
INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: Cognitive status was assessed using the MoCA. The L Test of Functional Mobility (L Test) and the 2-minute walk test were used to estimate functional mobility and walking endurance.
RESULTS: In multivariable linear regression analysis, those who scored 2 on the visuospatial/executive functioning (out of 5) and language (out of 3) domains had statistically shorter distances walked on the 2-minute walk test than did those who scored the highest on these MoCA domains. These values were not clinically relevant. Time to complete the L Test for those who scored the lowest on the MoCA domains of visuospatial/executive functioning and delayed recall and 3 on the attention domain (out of 6) was significantly longer than that for those who scored the highest.
CONCLUSIONS: Individuals with lower extremity amputation have an increased risk of cognitive impairment related to amputation etiology. Lower levels of functioning on MoCA domains of visuospatial/executive functioning, delayed recall, and attention were shown to negatively relate to the rehabilitation outcome of functional mobility, as measured by the L Test.
