212 Chapter 8 Figure 3: Individual change of M-SFS score from baseline to try-out measurement. The data points above the red line represent an increase in total M-SFS score compared to base measurement. The data points below the red line represent a decrease in total M-SFS score compared to base measurement. Low scores in the BASE condition tended to coincide with a large change. Figure 3 presents the difference of self-efficacy score from BASE measurement (x-axis) to TRY-OUT measurement (y-axis) for individual participants. We found that most of the participants started with a MSFS-score higher than the cut-off value (>56). Specifically, participants with a low MSFS-score at base measurement showed the biggest increase in MSFS-score. The effects of the exoskeleton on self-efficacy in the 5 categories are presented in Figure 4. For the categories Lifting, Repetitive Bending and Standing and Walking, a third of the participants rated higher self-efficacy after the try-out session. 47% of the participants showed higher scores in the TRY-OUT session for the task Static Forward Bending. In the categories Sitting and Others, only 12% and 14% of the participants rated higher self-efficacy.
