About

The goal of this clinical trial is to learn if a therapist training program can help providers in Part C Early Childhood Settings use powered mobility (PM) with young children who have cerebral palsy (Gross Motor Function Classification System Levels IV-V). The study will also look at whether this training is practical and useful for therapists, families, and children.

The main questions it aims to answer are:

1. Can therapists successfully use the training to provide powered mobility interventions in home and early childhood settings?
2. Do families and children find the intervention acceptable and helpful?
3. What benefits do children show in mobility, participation, and engagement after using powered mobility?

In this study, therapists and families will:

1. Take part in a training program about how to use powered mobility with young children
2. Use powered mobility devices (Permobil Explorer Mini) with children during everyday routines
3. Complete surveys, interviews, and observations about their experiences

Full description

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:

1. Identify provider needs and barriers through surveys and focus groups with providers.
2. 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.
3. 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.

Powered Mobility Intervention

Experimental group

Description:

This mixed-methods feasibility trial includes one experimental arm in which all participants receive the powered mobility intervention following a structured therapist training. Trained physical and occupational therapists participate in one to two days of in-person training to learn how to implement the intervention with children with cerebral palsy (GMFCS IV-V) and their caregivers in early childhood settings. Following training, therapists identify eligible child-caregiver dyads from their caseloads and conduct twelve biweekly home-based intervention sessions over six months. Each session focuses on mobility opportunities, caregiver coaching, and integration of powered mobility into daily routines using the Permobil Explorer Mini device. All sessions are video recorded for fidelity monitoring and qualitative analysis.
