Brief Summary:
Hemiplegia occurs when the function of motor areas in the brain become impaired, predominantly unilaterally, during perinatal development. Children with hemiplegia show impairments in motor control of the affected side of the body. Impairments in use of the upper extremity are common, and lead to functional disability throughout the lifespan of a person with hemiplegia. Upper extremity impairments can severely affect a person's ability to carry out activities of daily living.
The goal of this study at Blythedale Children's Hospital is to test the efficacy of transcranial direct current stimulation (tDCS) and robotic upper extremity therapy in improving upper extremity function in children with unilateral cerebral palsy. This study will test the hypothesis that physical rehabilitation, provided by repetitive arm movements guided by a robot, will improve upper extremity function in children with hemiplegia, and that this improvement can be enhanced by transcranial direct current stimulation of motor cortex immediately before robotic training.

Detailed Description:
This sham-controlled, double-blind study will be completed at Blythedale Children's Hospital.
Detailed procedures
Robotic Device and Patient Position
The investigators will use existing robots at Blythedale, which are FDA approved robotic devices that move the shoulder-and-elbow, or wrist-and-forearm, or the Typo Amadeo digit training robot.
All robots: The subject will sit in a foam-padded chair facing the robot and a video screen.
Planar (shoulder-elbow) and wrist robots: The arm will be abducted, forearm supported, and hand lightly grasping the robot handle, and velcro straps will lightly hold the forearm and fingers secure. A cursor on the video screen will display the targets and track the movement of the patient's arm.
Amadeo: The arm will be abducted, forearm supported, and digits attached to the robot with magnets. Velcro straps will lightly hold the forearm and fingers secure. A cursor on the video screen will display the targets and track the movement of the patient's fingers.
Robotic Training
Participants will receive a total of 12 sessions comprising 1 hour of interactive robotic training. Participants will have two to four study visits per week. During one visit, the child will receive tDCS + 1 hr training on the shoulder-elbow MIT Manus robot, and on the second visit of the week, the child will receive tDCS + 1 hr training on the wrist MIT Manus robot.
The interactive robot features involve visuomotor tasks, moving the robotic manipulandum according to targets on a computer screen mounted at eye level. A key feature of MIT robots is the low near isotropic inertia and reduced friction in the robot arm so that, when appropriate, it can "get out of the way." The force required to move the robotic arm is minimal, comparable to moving unrestricted, and if a patient cannot move the robot arm, it will guide the limb to provide an adaptive sensorimotor experience.
Transcranial Direct Current Stimulation
A current up to 1.5mA current will be delivered using surface rubber-carbon electrodes (35cm2) with surrounding saline soaked sponges (0.9% NaCl) by a battery driven, constant current stimulator (maximum output 2mA). Participants will receive stimulation for 20 minutes while seated (before robotic motor training), with the anode over the optimal site for first dorsal interosseous (FDI) as identified using TMS, and the cathode on the contralateral supraorbital area. Sham tDCS: comparable set-up to real tDCS, 30 sec real current ramping to current up to 1.5mA at commencement, then after 5 sec a slow decrease but to no current sustained for 20mins.
