Because of the significance of the
correlation of the scores for these
test items with the total PBS score,
they were further analyzed to determine
significance before and after
the intervention. For analysis of
single-leg stance, the times that
each child spent in single-leg stance
were averaged for the right and left
lower extremities. As a group, the
children showed a median increase
in time spent in single-leg stance
of 2.5 to 2.7 seconds, which was
a statistically significant increase
from the baseline assessments
to the postintervention assessment
(213.24, df2, P.01) (Tab. 3).
Analysis of tandem stance revealed
that the children, as a group, showed
median increases in standing time
of 8.5 and 2.5 seconds from the
baseline 1 and baseline 2 assessments,
respectively, to the postintervention
assessment
