This article summarizes subject and clinician
recommendations to improve a prototype multifunction
upper-limb prosthesis, the DEKA Arm, and reports
on subjects’ satisfaction and usability ratings
for two DEKA Arm prototypes (second-generation
[gen 2] and third-generation [gen 3]). Subjects completed
surveys on prosthetic satisfaction and usability.
Compared with gen 2 users, gen 3 users were
more satisfied with appearance, grips, and ease of
removing prosthesis and rated overall usability higher.
Features of gen 3, including weight, external cables and
wires, hand covering, and fingernails, would benefit
from further optimization. Many people with
upper-limb amputation are dissatisfied with the state
of the art of available prostheses. The DEKA Arm
has the potential to improve prosthetic satisfaction
and prosthetic usage and ultimately lead to improved
quality of life for Veterans with upper-limb amputation.
