FIGURE 8.14
Comparison of lifting determinants between simulation and experiments.

In general, the predicted lifting motion has shown a good correlation with the
experimental data. First, they stay inside the normal region specified by the inter-
val of confidence (outer dashed curves). Additionally, they show similar trends to
those of

the mean (the middle dashed curve) for the normal subjects.
