Objective
To investigate differences between self-reported cognitive concerns in people with lower limb loss (LLL) and normative data derived from the U.S. general population. A secondary aim was to determine if there were cognitive differences based on amputation etiology or age.
Design
Survey.
Setting
General community.
Participants
A volunteer sample of 1086 persons with LLL resulting from trauma or dysvascular complications who regularly use a prosthetic limb.
Interventions
Not applicable.
Main Outcome Measure
The Quality of Life in Neurological Disorders Applied Cognition General Concerns v1.0 Short Form (Neuro-QoL ACGC), an eight-item self-report measure of general cognitive concerns.
Results
People with LLL reported significantly more cognitive concerns than the Neuro-Qol normative sample. Mean Neuro-QoL ACGC scores were significantly lower than normative values (p<0.001) across subgroups defined by age (i.e., <40, 40–49, 50–59, 60–69, and 70+ years) and subgroups defined by etiology (i.e., traumatic and dysvascular LLL). However, there were no significant differences in cognitive concerns among age subgroups (p=0.84) or between the etiology subgroups (p=0.58).
Conclusions
When compared to the Neuro-QoL normative sample, individuals with LLL report greater concerns with cognitive health. Cognitive concerns were not differentially affected by age or cause of amputation. The presence of cognitive concerns in people with LLL suggests a need to assess perceived cognitive function in order to tailor education and training in prosthetic use and care.
