Evidence-based assessment pathways inform early detection of cerebral palsy and access to intervention. This study investigated the relationships between early evidence-based assessments, diagnosis timeline, and rehabilitation intervention access in a population of children with cerebral palsy who were seen between 2010 and 2022 at the University of Wisconsin Waisman Center Newborn Follow Up Clinic. Cerebral palsy–specific assessments were increasingly integrated after the publication of early detection guidelines by Novak et al. in 2017. Age at cerebral palsy first mention (high risk for cerebral palsy) decreased over time, although age at diagnosis remained similar. Infants who received multiple evidence-based assessments were diagnosed at a younger age. Ninety-nine percent of children were referred to rehabilitation therapies before diagnosis. Infant age at referral to outpatient therapies decreased over time. This study provides novel clinical data on diagnosis timelines and identifies remaining gaps related to implementation feasibility toward improved early diagnosis and intervention access.

Single-pulse transcranial magnetic stimulation (TMS) has many applications for pediatric clinical populations, including infants with perinatal brain injury. As a noninvasive neuromodulation tool, single-pulse TMS has been used safely in infants and children to assess corticospinal integrity and circuitry patterns. TMS may have important applications in early detection of atypical motor development or cerebral palsy. The authors identified and summarized relevant studies incorporating TMS in infants, including findings related to corticospinal development and circuitry, motor cortex localization and mapping, and safety. This special report also describes methodologies and safety considerations related to TMS assessment in infants, and discusses potential applications related to diagnosis of cerebral palsy and early intervention. Single-pulse TMS has demonstrated safety and feasibility in infants with perinatal brain injury and may provide insight into neuromotor development and potential cerebral palsy diagnosis. Additional research in larger sample sizes will more fully evaluate the utility of TMS biomarkers in early diagnosis and intervention. Methodological challenges to performing TMS in infants and technical/equipment limitations require additional consideration and innovation toward clinical implementation. Future research may explore use of noninvasive neuromodulation techniques as an intervention in younger children with perinatal brain injury to improve motor outcomes. Single pulse transcranial magnetic stimulation (TMS) is a safe and noninvasive way to study brain activity in infants and children who have experienced brain injuries around the time of birth. Infants who have had an early brain injury may develop cerebral palsy, a developmental disability that affects movement. TMS uses a device that gives single pulses of energy to activate specific areas of the brain. This can be used to study how the brain connects to the muscles in the body through paths or 'tracts.' TMS helps researchers understand the development of the tracts and the potential need for therapy. This article reviews research studies that used TMS in infants and explains how TMS can be used to assess brain development. It also reviews safety considerations and challenges related to using TMS in infants. TMS could be a valuable tool for early diagnosis of cerebral palsy and could also help guide treatments for infants with brain injuries. However, more research is needed, using larger groups of infants, to potentially expand the use of TMS in clinical practice. Future directions include developing infant-specific research tools and using noninvasive brain stimulation to improve recovery for infants with brain injuries. [ABSTRACT FROM AUTHOR]
