Effects of Intensive Robot-assisted Therapy in Patients With Subacute Stroke

In the researchers' words

Robot-assisted training (RT) devices developed to date have a significant impact on stroke rehabilitation. Several research groups have developed the robotic devices and examined their efficacy on improving upper limb function after stroke. All these robotic devices have been applied in stroke rehabilitation and their efficacy are evaluated, but the scientific evidence for the mechanisms of RT-induced recovery, the optimal treatment intensity, and the impact on physiological responses is still lacking. This trial is to examine (1) the immediate effects of treatment intensity in RT on sensorimotor impairments and functional performance in patients with subacute stroke; (2) the long-term benefits of treatment intensity in RT by conducting a 6-month follow up evaluation; and (3) the effects of RT on cortical/movement reorganization as well as on the physiological markers of inflammation, oxidative stress, and erythrocyte deformability. These overall findings will help better understanding of the efficacy of RT on functional outcomes, brain and movement reorganization, and physiological markers.
