Immediate Effects of PETTLEP-Based AOMI on Upper Limb Kinematics in Stroke Survivors

The purpose of this study is to investigate the immediate effects of a mental practice technique, called Physical, Environment, Task, Timing, Learning, Emotion, Perspective (PETTLEP)-based Action Observation and Motor Imagery (AOMI), on arm movement in stroke survivors. Stroke often causes difficulty in moving the arm smoothly, leading patients to compensate by using their back or shoulder. In this study, participants will either receive a single session of the AOMI training (watching and mentally practicing a reach-to-grasp movement) or a control relaxation task. The researchers will use a smartphone-based motion capture system (OpenCap) to measure if the mental practice immediately improves the smoothness of the arm movement and reduces compensatory body movements.
