Motor Imagery Added to Robot-Assisted Hand Rehabilitation After Stroke

In the researchers' words

Loss of upper extremity and particularly hand function after stroke reduces independence in daily activities such as eating, dressing, and personal care. Robot-assisted hand rehabilitation provides repetitive, intensive, and task-oriented practice that supports motor learning, dexterity, and functional hand use. Motor imagery, the mental rehearsal of a movement without physically performing it, is thought to activate motor-related brain networks and to support motor learning and neuroplasticity. Evidence on the added value of combining motor imagery with robot-assisted hand rehabilitation for activities of daily living is limited. This randomized controlled trial will investigate whether motor imagery training added to robot-assisted hand rehabilitation produces greater improvement in activities of daily living than robot-assisted hand rehabilitation alone in individuals with stroke. Forty participants will be randomly allocated to an experimental group (robot-assisted hand rehabilitation plus motor imagery, n=20) or a control group (robot-assisted hand rehabilitation alone, n=20). Both groups will receive the same dose of robot-assisted hand rehabilitation with a soft robotic hand rehabilitation glove, three days per week for six weeks. Outcomes will be assessed at baseline and after the six-week program.
