This study aims to assess the validity of a hand laterality discrimination task in patients who have suffered a stroke. The protocol involves two assessment sessions consisting of a Single Reaction Time (SRT) task and a Hand Laterality Judgement Task (HLJT). In the HLJT, participants are presented with images of right or left hands at various degrees of rotation and must determine the laterality of each hand. Primary outcomes include reaction time for the SRT, and both accuracy (percentage of correct responses) and decision-making time for the HLJT. Additionally, motor and kinesthetic imagery scales, as well as demographic and cognitive variables, are recorded.
