The Kinarm exoskeleton robot, tasks performed in this study, and characteristics of the Task Score distribution. a) Participants were seated and moved their arms in the horizontal workspace underneath a semi-transparent glass sheet. Tasks were projected onto the glass from above. Vision of the hands was obscured, however visual feedback was provided in most tasks. b) Participants completed 8 behavioural tasks testing motor, cognition-motor, cognitive, and sensory behavioural domains. VGR, RVGR, and APM were performed in each arm individually, yielding 2 datasets for each of these tasks. c) The Task Score cumulative density function (CDF) approximates that of the standard Normal distribution. A Task Score of 0 is the best, and increasing values reflect poorer performance. The distribution of Mahalanobis distance scores (M-Scores) is the same
