Overview
The goal of this clinical trial is to evaluate the effects of a high-intensity exercise program on recovery in individuals with post-stroke aphasia. The high-intensity exercise program has been specifically designed for individuals with post-stroke aphasia and includes an interval training full-body workout, which can increase cardiovascular fitness, improve muscle strength and motor performance, and maximize cognitive and language gains. The main question this study aims to answer is:
• Does participation in a high-intensity exercise program lead to changes in physical health, language, cognitive, motor recovery, psychological and/or psychosocial domains?
Participants will be randomly assigned to either a high-intensity exercise program (target intervention) or a low-intensity exercise program (control intervention) delivered over 12-weeks in a group setting.
Outcome measures will be collected once immediately after the intervention period and once during the following 12-week maintenance period to capture short- and long-term effects of the exercise program.
