Bilateral, Misalignment-Compensating, Full-DOF Hip Exoskeleton: Design and Kinematic Validation

Table 3

Mean, median, minimum, and maximum values of pelvic obliquity and pelvic rotation amplitudes during walking for each of the subjects in each of the 3 equipment states. values are unitless and reflect the probability that the median value of the prototype (PT) and 1-DOF (1D) trial does not differ from that in the unequipped (UE) trial. As values reflect the result of a comparison with the UE state data, they are not relevant (N.R.) for the UE state itself.
