The 95% confidence intervals are shown in dashed lines for the walking determinants.
The experimental subject's mean is shown in gray and Santos s 's determinants are shown
in black.

within the region; however, the simulation curve, while shifted vertically, is still
within the interval of confidence. There is a lesser degree of correlation between
the ankle dorsi-flexion and normal human motion, specifically in the second third
of the cycle. The general trend line of the pelvic tilt seems to agree with the
experimental curves. The pelvic tilt falls outside the 95% confidence interval
from 35% to 50% of the gait cycle when the ANOVA test shows that
0.001.
The pelvic rotation of the predicted model is well correlated to that of the human
subjects. In terms of lateral pelvic displacement, the simulation provides a rela-
tively normal curve, but the peak values occur at different percentages of the gait
cycle than were seen in the subject population.
