Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In this study, the MRI scans will include diffusion tensor imaging (DTI) - an established method used to investigate the integrity of pathways in the brain that control limb movement. Infants will be scanned during nature sleeping after feeding. The real scanning time will be less than 38 minutes. TMS is a painless, non-surgical brain stimulation device which uses principles of electromagnetic induction to excite cortical tissue from outside the skull. Using TMS as a device to modulate and examine cortical excitability in children with hemiparetic CP and in adults has been conducted previously.
In this infant study, we will assess cortical excitability from the motor cortex of both the ipsilesional and contralesional hemispheres under the guidance of a frameless stereotactic neuronavigation system. Additionally, the investigators will assess infants' movement quality using an age-appropriate standardized movement assessment. This will allow the investigators to examine the relationship between measures of motor pathway integrity and early signs of potential motor impairment. We will longitudinally follow enrolled infants, and complete repeat assessments at 12- and 24-months corrected age to assess how infants develop over time after perinatal stroke. The remote follow-up will occur at 5 years or less.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Identifying the association between laboratory assessment results and developmental outcomes is also critical. This study is to use MRI/DTI and TMS to comprehensively examine both the CST integrity and cortical excitability in infants following perinatal stroke, and to identify association with motor outcome as evaluated by movement assessment.
