Arm Position Matching task data

Dataset Description This repository processes proprioception data from four arm position matching (APM) studies. In the APM task, participants move their dominant arm to a target position and then reproduce that position with the other arm. Kinematic data (hand positions, target positions) were recorded with a KINARM endpoint robot. Studies Vandevoorde et al. (2021) Participants: 74 (36 young adults, 38 older adults) Task version: 9 targets Hand tested: Right Parthasarathy et al. (2022) Participants: 125 across two experiments (Exp1: 62, Exp2: 63; 64 young adults, 61 older adults) Task version: 9 targets Hand tested: Right Saenen et al. (2023) Participants: 100 (40 young adults, 60 older adults) Task version: 9 targets Hands tested: Right and Left Van De Plas et al. (2026) Participants: 73 (37 young adults, 36 older adults) Task version: 4 targets Hands tested: Right and Left Age groups Young adults (YA): ≤ 39 years old Older adults (OA): ≥ 60 years old Data Each participant/hand yields one CSV file with the following columns: trial_number, frame, time, absolute_time, Right_HandX, Right_HandY, Left_HandX, Left_HandY, TargetX, TargetY Positions are in meters. absolute_time is continuous across trials (seconds since session start).
