The paper presents a 3D healthcare informatics support for Hand Rehabilitation after injury. As a novelty, the application uses the Leap Motion sensor for patient's gestures recognition, and videos to illustrate to the users the hand exercise to perform. The implemented application provides feedback to users regarding the correctness of the performed recovery gestures/exercises. The data related to hand rehabilitation is saved in a database and offers to the Medical Rehabilitation Experts the possibility to monitor the patients in a more consistent manner. To assess the efficiency and accuracy of the application the application will be tested following a usability plan.
