Brief Summary:

The primary objective of this proposal is to investigate the safety of use of transcranial Direct Current Stimulation (tDCS)in children with hemiparesis.

The research question, "Is transcranial Direct Current Stimulation safe for use in children with congenital hemiparesis?" relates to two hypotheses:

1. tDCS will not produce a major adverse event, including seizure activity.
2. No change in paretic or nonparetic hand function or cognitive status will occur.

Condition or disease	Intervention/treatment	Phase
Hemiparesis	Device: tDCS	Early Phase 1

Detailed Description:

Completing a pilot safety study is paramount to the future goal of incorporating the tDCS pediatric safety data and combining tDCS and rehabilitation with constraint-induced movement therapy in order to improve motor outcomes beyond what rehabilitation therapies alone can provide and enhance quality of life for these children with hemiparesis.

Primary Outcome Measures :

1. Adverse Events/Safety Assessment. [ Time Frame: Baseline, Posttest, Follow-Up Session at One-Week ]

   Assessment of safety of use of tDCS in children with hemiparesis through vital signs, physician evaluation, subject report of symptoms. Reported are the number of participants who met the following criteria:

   1. Vital Signs (either resting blood pressure or heart rate)- Any greater than 2SD of change in vital signs from pretest to posttest.
   2. Physician Evaluation- Child identified as declining in function from pretest to posttest.
   3. Subject Report of Symptoms- Reports of serious adverse event/symptoms from pretest to posttest.

   Detailed adverse events are reported in the adverse events module.

Secondary Outcome Measures :

1. Hand Function Decline as Measured by Number of Participants [ Time Frame: Baseline, Posttest, Follow-Up Session at One-Week ]
   Measured by the Box and Blocks Test and Grip Strength
