163 Chapter 6 in performance in static forward bending (p=0.000) and the decrease in performance in wide stance (p=0.008) occurred for the low back pain group only. Figure 2a: Change in objective performance for the various tasks. *Significant change in functional performance between exoskeleton (with) and control condition (without). To facilitate comparison of the different tasks, values were normalized to score in the control condition (without exoskeleton). The dotted lines represent the division between the groups of tasks. Figure 2b : Change in objective performance in the subgroups healthy participants compared to participants with a history of low-back pain. *Significant difference in functional performance between exoskeleton (with) and control condition (without) in the respective group. 6
