Statistical measures of motor sensory and cognitive performance across repeated robot-based testing

摘要

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
