Figure 8

The effect of PB on the interaction forces and motion range of pelvis. Vertical bars indicate the average value and standard deviation over the different subjects. Significant difference between RAPBT walking (WR), RAPBT walking with PB (PB), and RAPBT walking with PB and admittance control (WQ) are indicated with a for and with a for .
