Early interventions in infants with unilateral cerebral palsy: A systematic review and narrative synthesis.

BACKGROUND

Recent systematic reviews have already provided an overview of the impact of early interventions on developmental outcomes in infants at risk for cerebral palsy. However, none has thus far focused specifically on how early interventions might improve motor outcome in infants diagnosed with unilateral cerebral palsy (uCP). Hence, the aim of this systematic review was to provide an overview of early intervention programs used in infants with uCP to improve motor outcome.

METHODS

A systematic literature search was performed in PubMed, Embase, Cochrane Central Register of Controlled trials, CINAHL and Web of Science following the PRISMA-statement guidelines. Risk of bias was assessed using the Cochrane risk-of-bias 2 tool.

RESULTS

Three single-blinded randomized controlled trials (RCTs) were identified, including 88 infants with uCP. These RCTs suggest that modified constraint-induced movement therapy (mCIMT) is effective and safe for improving upper limb function in infants with uCP. Bimanual training compared to mCIMT was found to be equally effective in one study. No clinical or neurological predictors of treatment response could be identified yet.

CONCLUSION

Although more high-quality RCTs are urgently needed, early interventions seem effective, safe and feasible to apply in infants with uCP for improving upper limb motor function. This underlines the importance of prompt referral to diagnostic-specific centres to start up such early interventions.
