The Small Step Program - Early Intervention for Children With High Risk of Developing Cerebral Palsy

Cerebral Palsy Clinical Trial

Official title: The Small Step Program - Early Intervention for Children With High Risk of Developing Cerebral Palsy

Status Completed

Clinical Trial Summary

Children with cerebral palsy (CP) have life-long motor disorders caused by brain injuries which occur around birth. These children go through extensive treatment during childhood, but the treatment has generally been started late due to late diagnosis (median age 15 months). New recommendations state that the clinical diagnosis "high risk of CP" should be given before 6 months corrected age, in order to be able to intervene as early as possible, and have the best possibilities to prevent or limit the adverse neurodevelopmental consequences of brain injuries occurring around birth. Thus, there is a great need to develop evidence-based early interventions for children at high risk of developing cerebral palsy. The Small Step program is developed at Karolinska Institutet (KI) in Stockholm, Sweden and is based upon theories of brain plasticity induced by early learning. The efficacy of the program is presently being investigated at KI. Preliminary results indicate a large individual variation in response to the program among the participating children. The aim of the present study is therefore to explore individual responses to the Small Step Program in infants at risk of developing cerebral palsy. The main hypothesis is that infant characteristics, such as severity of brain pathology, are associated with differential response to the program. Also, infants with absent fidgety movements and children with sporadic fidgety movements are believed to respond differently to the program.

Clinical Trial Description

The efficacy of the Small Step program is presently being investigated through a randomized controlled trial (NCT02166801) at Karolinska Institutet (KI) in Stockholm, Sweden. In the original project proposal for the current study, the plan was to contribute with inclusion of children from St. Olavs Hospital to the randomized controlled study initiated at KI. This project proposal has previously been approved by the Regional Ethical Committee (REK) for Medical Research in Mid-Norway (2016/1366). However, the researchers at KI have now completed the inclusion of participants for the randomized controlled study, and their preliminary results indicate that there is a large individual variation among the included participants regarding effect of the Small Step program. In agreement with the researchers at KI, it was therefore decided to change the design of the current study using Single Subject Research Design, a study design that is more appropriate to investigate individual response to treatment. The change in study design has been approved by REK (2016/1366-10). Participation in this study is based on informed consent from the parents, and the child and the family participating in the project will be offered a potentially effective early intervention program that they would otherwise not be able to access. The Small Step intervention program has three alternating treatment foci (B, C, and D) divided into five different steps, each lasting for 6 weeks (in total 30 weeks). The three treatment foci are Communication, Hand function and Mobility/gross motor function. The Hand function and Mobility steps will be conducted during two time-periods and the order will be randomised. Communication will have one intervention period during step III. The training will be conducted in the children's home by the parents on a daily basis under weekly supervision by the therapist responsible for each specific step of the intervention. General principles for the small step program are: a) collaborative goal-setting; b) promote infant's self-initiated actions; c) use of enriched home environment, d) intensity and repetition. Before and after the intervention, there is a baseline phase with no treatment (A) and a withdrawal phase with no treatment (A), resulting in the following design: A-B-C-D-B-C-A. In addition, there is a follow-up phase when the children are 2 years of age. ;
