Here we investigated the feasibility of a novel robotic task-practice system ADAPT designed in accordance with such guidelines. At each trial ADAPT selects a functional task according to a training schedule and with difficulty based on previous performance. Once the task is selected the robot picks up and presents the corresponding tool simulates the dynamics of the tasks and the patient interacts with the tool to perform the task. Methods Five participants with chronic stroke with mild to moderate impairments 9 months post-stroke Fugl-Meyer arm score practiced four functional tasks selected out of six in a pre-test with ADAPT for about one and half hour and 144 trials in a pseudo-random schedule of 3-trial blocks per task. Results No adverse events occurred and ADAPT successfully presented the six functional tasks without human intervention for a total of 900 trials. Qualitative analysis of trajectories showed that ADAPT simulated the desired task dynamics adequately and participants reported good although not excellent task fidelity. During training the adaptive difficulty algorithm progressively increased task difficulty leading towards an optimal challenge point based on performance difficulty was then continuously adjusted to keep performance around the challenge point. Furthermore the time to complete all trained .
