ABSTRACT
Table 10.1 Finger muscle forces predicted by optimisation (expressed as a ratio of tendon tension to externally applied force) using a variety of objective functions.
tasks while the tension in their tendons were being recorded. Table 10.2 provides the measured forces and ranges of forces predicted by models (An et al., 1985; Chao et al., 1989; and Cooney and Chao, 1977). Although measurements of forces during tip pinch were outside the range of model predictions, lateral pinch measurements agreed well. The in vivo measurements do confirm model predictions that tendon forces are greater than the applied force, sometimes by a significant amount.
