Summary

This study tests whether a 12-week high-intensity exercise program can improve language, thinking, and physical health in 120 adults with aphasia (trouble speaking or understanding language) after a stroke. Participants are randomly assigned to either high-intensity or low-intensity group exercise. The goal is to see if vigorous workouts lead to better recovery in language and overall well-being.
