Include criteriaPatients with chronic stroke (6 months or more post-onset) who have hand function impairment. Age 18 years or older. Able to provide written informed consent after adequate explanation of the study objectives and methods
Exclude criteriaSevere cognitive impairment or severe communication disorder that makes it difficult to understand instructions or carry them out. Unstable vital signs. PR. (Heart rate greater than 120 beats per minute. Symptomatic bradycardia, for example a heart rate less than 50 beats per minute.
