Usability is an important topic in the field of
telerehabilitation research. Older users with disabilities in
particular, present age-related and disability-related challenges
that should be accommodated for in the design of a user
interface for a telerehabilitation system. This paper describes
the design, implementation, and assessment of a
telerehabilitation system user interface that tries to maximize
usability for an elderly user who has experienced a stroke. An
Internet-connected Nintendo® Wii™ gaming system is selected
as a hardware platform, and a server and website are
implemented to process and display the feedback information.
The usability of the interface is assessed with a trial consisting
of 18 subjects: 10 healthy Doctor of Physical Therapy students
and 8 people with a stroke. Results show similar levels of
usability and high satisfaction with the gaming system interface
from both groups of subjects.
