The RGS setup. a: Microsoft Kinect sensor captures the movements of the user’s upper limbs and maps them into an avatar displayed on a screen in first person perspective so that the user sees the upper extremities. b: The experimental protocol is divided in two sessions (S1 and S2) comprising a Real World Task (RWT), a Virtual Reality Task, and a Questionnaire (Q). The amplification of the virtual movement of the paretic limb (green line) is manipulated during the Virtual Reality Task, which is divided in 3 phases (P1, P2, and P3). Horizontal red lines indicate blocks of trials for which performance measurements are considered for analysis. Vertical red rectangles indicate forced trials. White rectangles indicate free choice trials. c: VR and RW tasks, top: participants performed consecutive reaching movements in VR, bottom: participants performed consecutive pointing movements towards targets located at different angles corresponding to the paretic, center, or non-paretic workspace
