Constraint-Induced Movement Therapy for Infants With or at Risk for Cerebral Palsy: A Scoping Review.

Importance: Although research shows that older children with hemiplegic cerebral palsy (CP) benefit from constraint-induced movement therapy (CIMT), the efficacy of CIMT among the infant population is unknown.

Objective: To explore the existing evidence on CIMT for infants age 24 mo and younger with CP or at risk for CP.

Data Sources: PubMed, CINAHL, Cochrane, and ProQuest were searched. Study Selection and Data Collection: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and American Occupational Therapy Association guidelines were used for abstracting data and assessing data quality. Two frameworks guided this scoping review. Studies met the following criteria: infants with hemiplegic CP, published in English between 2000 and 2020, peer reviewed, and addressed changes in upper limb function of the hemiplegic upper limb.

Findings: Eight articles met the inclusion criteria: 2 randomized controlled trials, 1 retrospective cohort design, 1 pretest-posttest study, 2 single-subject studies, and 2 case studies. In this scoping review, we examined CIMT protocols for an overview of dosage, constraint, administration, parent training and education, and objective outcome measures.

Conclusions And Relevance: Existing literature supports CIMT protocols for infants with CP. However, much variability exists in protocol design and appropriate outcome measures among studies. Higher level research is needed to support the efficacy of CIMT among infants with CP. What This Article Adds: This scoping review summarizes the existing literature on CIMT for infants with hemiplegic CP. This information can help guide therapists to implement CIMT protocols in the clinical setting and to identify additional research to establish practice standards.
