Abstract
Dynamic stability limit is the farthest
distance where the center of body mass
can approach during a dynamic task. It
has been reported highly correlated with
the anticipatory postural adjustment. The
purposes of this research were to
investigate the effect of neuromaucular
stimulation on the dynamic stability limit
in a forward reach task.
Twenty healthy volunteers were
recruited to performed seated reach
movement tasks in different conditions.
The conditions included no sitmulation,
stimulating both the tibialis anterior and
the gastrocnemius, stimulating both the
quadriceps and hamstrings, and
stimulating all of those 4 muscles.
Kinematic data collected by Vicon 250 and
processed using a self-programmed
LabVIEW program. The seated
functional reach distances were compared
for each condition using ANOVA with
repeated measures. Kinetic data
collected by 2 AMTI force platforms were
processed using a LabVIEW program.
The excursion of the center of pressure
were compared for each condition using
ANOVA with repeated measures. The
significant level was set at α=0.05.
Results revealed that there was no
statistically significance in either the
seated functional reach distance or the
excursion of the center of pressure among
different neuromuscular conditions. The
possible explanations were 1)small sample
size, 2) insufficient electric current, 3) the
ceiling effect of the dynamic stability limit.
Future studies would direct to investigate
the mechanism of seated dynamic stability
limit using larger sample size and using
different types of stimulation.
