Brief Summary
The purpose of this study is to test tDCS (transcranial direct current stimulation), a type of non-invasive brain stimulation, to determine whether it can improve motor function in children with perinatal stroke and hemiparesis. Children 6-18 years with imaging-confirmed perinatal stroke and functional motor impairment will be recruited. Children will be randomized (1:1) to receive sham or tDCS (20 minutes daily) during daily intensive, goal-directed motor learning therapy (90 minutes). Motor outcomes will be repeated at baseline, 1 week, and 2 months. Aim 1: Establish the ability of tDCS to safely enhance motor learning in children with perinatal stroke. Hypothesis 1: tDCS is safe and well tolerated in children. Hypothesis 2: Contralesional, cathodal tDCS increases motor functional gains measured by AHA at 2 months in children with perinatal stroke.

Outcome Measures
Primary Outcomes (1)
Change from baseline in the Assisting Hand Assessment (AHA) at 8 weeks
This is the established standard for the objective quantification of bilateral hand function in children with hemiparetic CP.This Rasch-built evaluation carries the strongest evidence of inter-rater, intra-rater, and test-retest reliabilities, test-validity, and responsiveness to change for bimanual tasks in children within our age range For more details about this measures please refer to the published literature.
8 weeks

tDCS Safety and Tolerability evaluation (TST)
Each day following the tDCS treatment (10x)
Change from baseline in the Canadian Occupational Performance Measure (COPM) at 1 week

Study Arms (2)
Interventional tDCS
EXPERIMENTALThe primary intervention will be cathodal (inhibitory) tDCS (see below).
Sham tDCS
SHAM COMPARATORSham subjects will undergo exactly the same tDCS protocol as outlined above. This includes the initial stimulation sequence, generating the initial transient scalp sensations identical to the treatment group. The stimulator will be programmed by the technologist to automatically ramp down to off over 30 seconds after 120 seconds of stimulation.
Interventions
The primary intervention will be cathodal (inhibitory) tDCS over non-lesioned M1. This will be targeted using TMS baseline mapping data and neuronavigation (Brainsight2, Rogue Research, Montreal) individualized to the subjects MRI. Soft, replaceable 25cm2 electrodes will be placed over clean, dry scalp with the cathode over marked M1 and the reference electrode over contralateral forehead/orbit consistent with standard protocols. The current-controlled DC stimulator (neuroConn GmbH, Ilmenau, GE) will be turned up slowly over 30 seconds to the treatment current of 1.0 mA. TDCS will be administered each day during the first 20 minutes of the 90 minute therapy session. Child, family, and both treating and measuring occupational therapists are blinded to treatment allocation.
