Abstract:
The authors’ aim was to determine which variables
allow for the characterization of motor balance behavior. Traditional
measures and nonlinear measures of center of pressure
(COP; n D 30) and kinematics (n D 10) were tested in their absolute
and relative consistency in a 30-s standing balance task protocol
under stable and unstable conditions. Regarding COP
variables, mean velocity (mVel), permutation entropy (PE) and
detrended fluctuation analysis (DFA) exhibited high consistency
between trials and ranked individuals more accurately compare
with other metrics. In the kinematic signal mVel, PE and DFA had
good intrasession reliability values in unstable conditions. Overall,
the intrasession reliability values were better in the unstable condition
than in the stable condition and the measures calculated using
derived data had better intrasession reliability values. In conclusion,
mVel, PE, and DFA allow for the good characterization of
motor balance behavior in a simplified protocol where velocity
time series are analyzed.
