[Purpose] The purpose was to examine relationships between variables characterizing the
20-second stepping test movement pattern, assessed with an infrared depth sensor
(Kinect
TM
), and measurements of dynamic and static balance. [Participants and
Methods] A total of 27 independent-living, older adults (7 males and 20 females)
participated in this study. For each participant, the stepping test total movement
distance, movement displacement, knee movement distance, and step number were calculated
from Kinect closed joint-point coordinate data. Dynamic and static balance were assessed
using a NeuroCom Balance Master Platform system. [Results] The stepping test total
movement distance had a moderate negative correlation with endpoint excursion (r=−0.469)
and a moderate positive correlation with total movement distance, corrected for knee
movement distance (r=0.557). Step numbers had a moderate negative correlation with
stepping test total movement distance (r=−0.667) and total movement distance, corrected
for knee movement distance (r=−0.531). Division into high and low-balance sub-groups
(based on endpoint excursion or sway velocity scores) revealed that stepping test total
movement distances and movement displacements were greater, and step numbers were fewer,
in low balance groups. [Conclusion] The stepping test, combined with a
Kinect
TM
-assessed movement pattern provides a simple, objective, reliable means
for assessing balance in community-dwelling, independent-living older adults.
