Is PARTNER, a hybrid HABIT-ILE programme with parent coaching, as effective as standard HABIT-ILE in children with cerebral palsy aged 3-5? A protocol for a multicentre, randomised controlled trial.

introductionHand-arm Bimanual Intensive Therapy Including Lower Extremities (HABIT-ILE) is an intensive rehabilitation programme for children with cerebral palsy (CP) delivered in a day camp setting recognised to promote the acquisition of specific functional abilities and independence. Currently, during HABIT-ILE camps, families are minimally involved in their child's motor learning processes. This explains the challenges reported by both families and therapists, including difficulties in reinforcing skills at home, limited transfer to other functional goals and a lack of confidence in parents' adaptive competence (self-determination and empowerment). Increasing family involvement in intensive motor rehabilitation programmes and the child's developmental process by reinforcing skills at home could help reduce the parental impact of the child's disability, enhance family satisfaction and strengthen their resources to support their child's daily learning during and after the camp.To address this, we developed the PARTNER programme, which combines HABIT-ILE with a structured home component focused on parent coaching. METHODS AND ANALYSIS: We designed a non-inferiority, mixed-methods, multicentre randomised controlled trial to compare the efficacy at 3 months of the PARTNER programme (35 hours HABIT-ILE+15 hours home programme) with the standard HABIT-ILE programme (50 hours) on the bimanual performance (Assisting Hand Assessment) of children with unilateral CP aged 3-5 years. The secondary aims are to compare the 3-month efficacy of the programmes on occupational performance, functional skills and upper limb activity levels, as well as families' resources, the parent-child relationship, the quantity and quality of resources available in the home to stimulate the child's motor development, and parental perceptions of their child's disability and their child's abilities (qualitative study). The tertiary aim is to conduct a cost-effectiveness analysis of care consumption in each group up to 6 months after the end of the programmes.Target recruitment is 66 children (33 in each group) from 3 centres in France. Outcomes will be evaluated before the interventions, immediately after, at 3 months and up to 6 months for the cost-effectiveness analysis. Families in the PARTNER group will receive specific coaching and extensive support to perform the home programme. The coaching will focus on enhancing their resources. ETHICS AND DISSEMINATION: The study protocol has been reviewed, and ethics approval obtained from the Protection of Persons Committee (PPC) (PPC number: 2024-A01051-46). The results from this study will be actively disseminated through manuscript publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT06963151.
