The purposes of this pilot research study are 1. To begin to test if two different types of physical therapy might have different results in children and adolescents who have had a prior stroke, and 2. To determine if either type of physical therapy causes changes in the brain signals that control leg muscles. All participants will receive physical therapy 3 times per week for 8 weeks. Half of the participants will receive typical physical therapy, such as walking practice, muscle strengthening, and balance training. Half of the participants will receive asymmetrical gait training physical therapy, which uses new technology to train each leg differently during walking practice. After enrolling, participants will be randomly assigned to the type of therapy. Measurements will be taken before, during, and after the 8 weeks of physical therapy. These include walking tests to measure symmetry, walking speed and daily step activity, and brain tests to measure the strength of the signals from the brain to the leg muscles. One blood test is also taken to identify if certain genetic factors affect how each child responds to the physical therapy.

We will also establish a genetic database to identify the presence or absence of two genetic variants [Apolipoprotein E (ApoE Є4) and val66met Brain-derived neurotropic factor (BDNF) polymorphisms] associated with decreased potential for neuroplasticity for planning future investigations. --- val66met ---
