Abstract
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.
