Current Environment:


The main goal of this study is to identify abnormal functional and anatomical brain reorganization associated with hand, foot, and shoulder function in children (0-18 years old) with cerebral palsy (CP) due to periventricular white matter injury (PV-WMI) or brachial plexus birth palsy (BPBP) using a multi-modal neuroimaging approach.

Detailed Description

This is a non-interventional study designed to assess changes in the sensorimotor cortex of children with CP as a result of PV-WMI and children with BPBP that combines multiple neuroimaging techniques to better visualize the resulting brain reorganization. The study design will be a mixed 3 (group: CP, BPBP, TD) x 2 (hemisphere: more affected, less affected) analysis of variance (ANOVA), with group being a between-subject factor and hemisphere a within-subjects factor. The research study plans to recruit and test 30 children with CP due to PV-WMI, 30 children with BPBP, and 30 aged-matched and typically developing (TD) children aged from 0 to 18 years old. Data from the participants will be collected over the course of four visits: (i) the recording session for the MEG, (ii) the recording session for the EEG, (iii) the MRI scanning session, and (iv) the TMS session. TD, CP, and BPBP subjects will be asked to commit to these visits. The MEG session will last ~3 hours with the actual measurements lasting ~60 minutes, the EEG session will last ~2 hours with the actual measurements lasting ~60 minutes, the MRI visit will last ~1 hour with the actual acquisition scan timing lasting ~30 minutes, and the TMS visit will last ~1 and a half hours with the actual acquisition time lasting ~45 minutes. Depending on the participant, the behavioral tests may be administered during any of the visits that the child is most comfortable and able to perform them.
