Figure Lengend Snippet: (A) The Kinarm Exoskeleton robotic device used to perform the Arm Position Matching (APM) Task. (B) An exemplar of the APM Task. Data taken from a stroke participant with normal performance (Task Score of 0.23). In this instance, the robot moved the participants stroke affected, left arm. Each filled symbol represents the mean position of one the nine targets where the robot moved the participant’s affected arm. The participant mirror-matched with the unaffected, right arm. The open symbols represent the mean position of each target where the participant moved their unaffected arm. Ellipsoids represent one standard deviation of variability around each matched position. For illustrative purposes the grey and solid black outlines connect the mean hand positions of the outer 8 targets for the robotically moved affected arm and participant moved arm, respectively. The data from the participant moved arm is also reflected across the midline of the participant, to make easier comparison to the target locations of the robotically moved passive arm (open symbols, outer targets connected by black dashed line). (C-E) Similar to (B), these panels demonstrate the participant’s attempts to match with the active arm (open symbols) reflected across the midline for comparison to the robotically moved hand positions (closed symbols). This has been done for illustrative purposes so the reader can make a direct visual comparison. Exemplars from stroke participants illustrate high amounts of variability (C), contraction (D) and systematic shift (E). It should be noted that while panel D) displays a participant with high amounts of contraction , it is also possible to observe examples of expansion of the workspace .
