Robot Mediated Therapy-Feasibility Study and Preliminary Effects

The goal of this clinical trial is to investigate the feasibility of the application of robot mediated impairment-training (RMIT) and robot mediated task-specific training (RMTT) in acute stroke patients with upper limb impairments. The main question\[s\] it aims to answer are: * Is it feasible and safe to conduct RMIT and RMTT in acute stroke patients with upper limb impairments? * What are the preliminary effects on the physical function and quality of life in these patients? Participants will undergo 20 hours of robot mediated upper limb therapy. Researchers will compare RMIT with RMIT+RMTT to see if there are any differences in the effects on physical function and quality of life.
