About

Residual neurological deficits from stroke lead to gait inefficiencies, resulting in an extremely high energy cost of movement and contributing to overall disability and lower quality of life. Therefore, interventions targeting movement economy should be developed for those in the chronic phase of stroke recovery. This study is designed to compare the effect of two distinctly different exercise paradigms (a higher-intensity treadmill training program and a lower-intensity group exercise program) on economy of movement during over-ground walking and activities of daily living, as well as the extent to which gains in muscular strength, muscular endurance, and balance predict changes in movement economy.
