Abstract Download PDFBackground and Objective: The main factor of fall
risk prevention in elderly is fall risk assessment; FRA.
Therefore, reliable assessment method is very important.
The purpose of this study was to define the
test-retest reliability of body center of mass (COM)
sway assessment while perform sit to stand using Kinect-
Based Exergames device in older adults.
Methods: Twenty older adults aged more than 60
years (mean age was 67.30 ± 5.58 years) were instructed
to performed Five Time Sit to Stand Test (FTSST)
while the body COM sway in 3 directions were evaluated
by Kinect and software which was developed.
The participants were assessed two trials with 1-week
resting period. The Intraclass correlation coefficients
(ICC3,1) was used to explore test-retest reliability and
significant levels were set at p < 0.05.
Results: The results showed that test-retest reliability
of body COM sway during FTSST was good reliability
(ICC3,1 were between 0.83 – 0.90).
Conclusion: The kinematics assessment of body COM
sway during FTSST which were evaluated by Kinect
and software which was developed is test-retest reliable
