Barriers, Facilitators, and a Proposed Model of Care for Implementation of Upper Limb Distributed Practice Approaches for Children with Unilateral Cerebral Palsy.

: There is high-level research evidence supporting task-focused upper limb therapy models for children with unilateral cerebral palsy (CP). However, a knowledge gap exists in understanding how to effectively implement distributed practice approaches in clinical practice and the effect on the development of bimanual performance. This study aims to evaluate clinical outcomes, examine key considerations for implementation outcomes, and propose a Model of Care for children with unilateral CP. : A mixed-methods approach was applied, including a retrospective case series with an observational descriptive design. A convenience sample of nine children (<5 years of age) with unilateral CP who received multiple blocks of distributed, evidence-based upper limb therapy approaches between 2014 and 2020 were included. Outcomes were evaluated using the Assisting Hand Assessment family of assessments. A Model of Care framework was informed by the Updated Consolidated Framework for Implementation Research and the Conceptual Model for Implementation Research. : A total of 59 blocks of upper limb therapy (10 mCIMT and 49 bimanual therapy) were delivered, ranging from two to nine blocks (mean = 6.6) for each child. All children demonstrated improved outcomes in bimanual performance with an average change of 14 AHA units (range 1-22). Barriers to implementation included complexity and cost. Facilitators included the evidence base and adaptability of the approaches that allowed clinicians to respond to an individual child and family's needs. Informed by evidence-based protocols and visual analysis of data, and in consideration of the barriers and/or facilitators to implementation from this study, a Model of Care for implementation of upper limb distributed practice approaches for children with unilateral CP in clinical practice is proposed. : Implementing repeated, distributed blocks of evidence-based upper limb therapy in a clinical setting for children with unilateral CP led to incremental improvements in bimanual performance. There are a range of barriers and facilitators to the implementation of distributed practice approaches in clinical practice. The Model of Care outlines best practice care and service delivery for children with unilateral CP and their families and aims to support clinical practice and the future examination of implementation-effectiveness in practice.
