167 Chapter 6 Figure 6: Boxplot (median, inter quartile range and total range) of general discomfort of the exoskeleton for the various tasks. The black dashed lines represent the division between the groups of tasks. The median values of user impression are presented in Table 3. Adjustability, including donning and doffing and length adjustment, was rated as easy. Range of motion with the device was reported to be only slightly restricted. The efficacy of the device in terms of reduction of back loading and support of the tasks was experienced as good to moderate. Interference of the exoskeleton with the tasks was considered to be low. The participants rated the SPEXOR exoskeleton with a final grade of 6 and a range of 5-7. To use the exoskeleton at work was still considered as rather unlikely. 6
