The objectives were to 1) identify major cognitive domains involved in
learning to use the DEKA Arm;
2) specify cognitive domain-specific skills
associated with basic versus advanced users; and 3) examine whether baseline
memory and executive function predicted learning. Method Sample included 35
persons with upper limb amputation. Subjects were administered a brief
neuropsychological test battery prior to start of DEKA Arm training, as well as
physical performance measures at the onset of, and following training. Multiple
regression models controlling for age and including neuropsychological tests were
developed to predict physical performance scores. Prosthetic performance scores
were divided into quartiles and independent samples t-tests compared
neuropsychological test scores of advanced scorers and basic scorers. Baseline
neuropsychological test scores were used to predict change in scores on physical
performance measures across time. Results Cognitive domains of attention and
processing speed were statistically significantly related to proficiency of DEKA
Arm use and predicted level of proficiency. Conclusions Results support use of
neuropsychological tests to predict learning and use of a multifunctional
prosthesis. Assessment of cognitive status at the outset of training may help set
expectations for the duration and outcomes of treatment. Implications for
Rehabilitation Cognitive domains of attention and processing speed were
significantly related to level of proficiencyof an advanced multifunctional
prosthesis (the DEKA Arm) after training. Results provide initial support for the
use of neuropsychological tests to predict advanced learningand use of a
multifunctional prosthesis in upper-limb amputees. Results suggest that
assessment of patients' cognitive status at the outset of upper limb
prosthetictraining may, in the future, help patients, their families and
therapists set expectations for theduration and intensity of training and may
help set reasonable proficiency goals.
