Abstract
Objective
To establish a comprehensive profile of cognitive functioning in people engaged in
lower limb amputation (LLA) rehabilitation.
Design
Cross-sectional study as part of a longitudinal prospective cohort.
Setting
A national tertiary rehabilitation hospital.
Participants
Adult volunteer participants (N=87) referred for comprehensive rehabilitation for
major LLA were sampled from 207 consecutive admissions. Participants with both vascular
(n=69) and nonvascular (n=18) LLA etiologies were included.
Interventions
Not applicable.
Main Outcome Measures
Demographic and health information and a battery of standardized neuropsychological
assessments.
Results
Compared to normative data, impairment was evident in overall cognitive functioning
(P≤.003). Impairment was also evident in particular areas, including reasoning, psychomotor
function, information processing, attention, memory, language/naming, visuospatial
functions, and executive functions (all P≤.003 Holm-corrected). There were also higher frequencies of impaired functions across
most aspects of functioning in this group compared with expected frequencies in normative
data (P≤.003 Holm-corrected). There were no significant differences in cognitive functioning
between participants of vascular and nonvascular LLA etiology.
Conclusions
Findings support the need for cognitive screening at rehabilitation admission regardless
of etiology. Administration of comprehensive neuropsychological assessment with a
battery sensitive to vascular cognitive impairment is recommended in some cases to
generate an accurate and precise understanding of relative strengths and weaknesses
in cognitive functioning. Cognitive functioning is a potential intervention point
for improvement of rehabilitation outcomes for those with LLA, and further research
is warranted in this area.
