Cerebral palsy (CP) is the most common cause of physical disability in childhood. Children classified at Gross Motor Function Classification System (GMFCS) Levels IV-V experience significant limitations in mobility and typically require assistive technology to move independently. These early months, between 12-36 months, are a critical period for brain development and learning. Without access to independent mobility, children with CP have fewer opportunities to explore, communicate, and engage socially, which can contribute to secondary developmental delays.
Power mobility (PM) devices, such as the Permobil Explorer Mini, provide opportunities for self-initiated exploration of a child's environment. Research has shown that access to PM in early childhood can promote cognitive, social, and motor development, while also supporting participation in family and community life. Despite this growing evidence base, PM use in Part C Early Childhood Settings is infrequent and inconsistent. Many families never receive the option of PM during their child's first years. Barriers include a lack of provider training, limited availability of devices, uncertainty about service delivery models, and the perception that PM should be delayed until school age.
This study directly addresses these gaps by developing and testing a training program for Early Childhood Setting providers to deliver PM interventions with young children with CP (GMFCS IV-V). The project uses a community-engaged, implementation science approach to ensure that the intervention is not only clinically meaningful but also feasible and sustainable within real-world Part C Early Childhood Setting systems.
The research is guided by three aims:
- Identify provider needs and barriers through surveys and focus groups with providers.
- Co-design a training program with input from a Community Advisory Board that includes clinicians, families, administrators and researchers. This process ensures that the training reflects real-world challenges and priorities.
- Conduct a feasibility trial to test the training program with providers and families of young children with CP.
The feasibility trial will combine implementation and child-level outcomes in an effectiveness-implementation hybrid design. Implementation outcomes will include acceptability, appropriateness, feasibility, and fidelity, using validated measures such as the Acceptability of Intervention Measure (AIM), Feasibility of Intervention Measure (FIM), and Implementation Appropriateness Measure (IAM). Fidelity will be examined through session recordings and coding of adherence to intervention strategies.
The intervention itself consists of therapist training in PM use, assessment, and caregiver coaching. Providers will be introduced to the Explorer Mini and will learn strategies to embed mobility into family routines. Therapists will then coach families to use PM with their children during everyday activities, both in the home and community. The emphasis is on real-world use, giving children opportunities to explore, make choices, and participate in their environments.
Child outcomes will include mobility, engagement, and participation, measured through caregiver report, standardized assessments, and observational coding of video-recorded sessions. Family experiences will be assessed through surveys and semi-structured interviews, to better understand acceptability and perceived benefits of PM.
This study is expected to generate critical pilot data on how PM interventions can be implemented in Part C Early Childhood settings, a setting where they are currently underutilized. By focusing on both therapist training and family engagement, this project bridges the gap between evidence and practice. Findings will inform larger-scale trials and lay the groundwork for integrating PM into standard Early Childhood setting services, ensuring that children with CP and significant motor impairments have earlier opportunities to move, explore, and participate fully in daily life.
