Telerehab Exerbrain: Bridging Physical and Cognitive Therapy in Stroke

The goal of this clinical trial is to learn if a web-based exercise and cognitive training (physical-cognitive) program works to improve movements and brain function in adults with long-term stroke. It will also learn whether the program is safe and enjoyable. The main questions it aims to answer are: Does the program improve walking, balance, strength, and reduce fall risk? Does the program improve cognitive skills such as memory, attention, and problem-solving? Researchers will compare the online exercise-and-cognitive training program to usual care to see if the program leads to greater improvements. Participants will: * Be randomly assigned to either the online training group or the usual care group * If in the training group, complete the home-based program for 12 weeks. * Take part in physical and cognitive tests before and after the program
