Abstract
The specific aim of this year-one part
of the three-year research project was to
compare the differences in the influence of
assistive device use on dynamic balance and
the associated attentional demands during
voluntary stepping in standing between
patients with stroke and age-matched
healthy individuals. Subjects were asked to
step forward, sideways, or backward, in
response to a stimulus light signal with the
left or right leg under a cane-free and a cane
(regular type)-assisted condition. In the cane
-assisted condition, healthy subjects used the
dominant hand and patients with stroke used
the unaffected hand to hold the regular cane.
To date, 8 (6 young and 2 older) healthy
subjects have participated in this study.
Reaction time, movement time, step length,
and the force dynamics of the cane were
calculated. The results showed that older
adults benefited from using the cane by
decreasing the reaction time and increasing
the movement time of the stepping
responses. The force dynamics of the cane
were task-specific, suggesting that even for
healthy adults, the use of a cane still
provides additional physical support for the
completion of the stepping movement.
These preliminary results will serve as
important reference information to be
compared with as we collect more data on
hemiparetic patients following stroke.
