Table 1.
The 47 attributes analysed. They included subject initial conditions (ankle and thigh angles) and experimental setup/anthropometric parameters (seat height, thigh length, foot length, TIP1 hinge and malleoli coordinates), KK-set variables and important time instants. The KK-set was made of displacements (Disp), velocities (Vel), forces or couples and powers referred to the two LA and SA actuators. So referred to seat-off. In addition, ML, AP and V referred to the medio-lateral, antero-posterior and vertical directions. Finally, the attributes labelled with an initial "T" represented the instant of occurrence of the corresponding quantity (e.g. the attribute MaxLAVelASO referred to the maximum value of LA velocity after the seat-off and the attribute TMaxLAVelASO represented the corresponding instant of occurrence).
