Insights
Constraint-induced movement therapy (Baby-CIMT) and bimanual therapy (Baby-BIM) similarly improved hand function in infants at high risk for unilateral cerebral palsy. Early intervention before 6 months showed greater hand function gains.
Area of Science:
- Pediatric Rehabilitation
- Neurology
- Developmental Pediatrics
Background:
- Infants at high risk for unilateral cerebral palsy often exhibit asymmetrical hand use.
- Early intervention is crucial for optimizing motor development and functional outcomes.
Purpose of the Study:
- To compare the efficacy of constraint-induced movement therapy (Baby-CIMT) versus bimanual therapy (Baby-BIM) in infants at high risk for unilateral cerebral palsy.
- To evaluate the impact of early intervention on hand function and developmental outcomes.
Main Methods:
- A single-blind, randomized-controlled trial involving 96 infants (3-9 months corrected age) with asymmetric brain lesions and absent fidgety General Movements.
- Infants were randomized to receive either Baby-CIMT or Baby-BIM home-based intervention for 6-9 months.
- Primary outcome was the Hand Assessment for Infants (HAI) score post-intervention; secondary outcomes included Mini-Assisting Hand Assessment and Bayley III cognition at 24 months corrected age.
Main Results:
- No significant difference in HAI scores between Baby-CIMT and Baby-BIM immediately post-intervention.
- Both interventions led to clinically significant improvements in hand function from baseline.
- Infants starting intervention before 6 months corrected age demonstrated greater improvements in hand function compared to those starting later.
Conclusions:
- Baby-CIMT is not superior to Baby-BIM for infants at high risk of unilateral cerebral palsy.
- Both therapies effectively improve hand development in this population.
- Early intervention (before 6 months corrected age) is associated with superior hand function outcomes.
Objective:
To compare efficacy of constraint-induced movement therapy (Baby-CIMT) with bimanual therapy (Baby-BIM) in infants at high risk of unilateral cerebral palsy.
Study Design:
This was a single-blind, randomized-comparison-trial that had the following inclusion criteria: (1) asymmetric brain lesion (2) absent fidgety General Movements, (3) Hammersmith Infant Neurological Examination below cerebral palsy cut-points, (4) entry at 3-9 months of corrected age, and (5) >3-point difference between hands on Hand Assessment Infants (HAI). Infants were randomized to Baby-CIMT or Baby-BIM, which comprised 6-9 months of home-based intervention. Daily dose varied from 20 to 40 minutes according to age (total 70-89.2 hours). Primary outcome measure was the HAI after intervention, with secondary outcomes Mini-Assisting Hand Assessment and Bayley III cognition at 24 months of corrected age.
Results:
In total, 96 infants (51 male, 52 right hemiplegia) born median at 37-weeks of gestation were randomized to Baby-CIMT (n = 46) or Baby-BIM (n = 50) and commenced intervention at a mean 6.5 (SD 1.6) months corrected age. There were no between group differences immediately after intervention on HAI (mean difference [MD] 0.98 HAI units, 95% CI 0.94-2.91; P = .31). Both groups demonstrated significant clinically important improvements from baseline to after intervention (Baby-BIM MD 3.48, 95% CI 2.09-4.87; Baby-CIMT MD 4.42, 95% CI 3.07-5.77). At 24 months, 64 infants were diagnosed with unilateral cerebral palsy (35 Baby-CIMT, 29 Baby-BIM). Infants who entered the study between 3 and 6 months of corrected age had greater change in HAI Both Hands Sum Score compared with those who entered at ≥6 months of corrected age (MD 7.17, 95% CI 2.93-11.41, P = .001).
Conclusions:
Baby-CIMT was not superior to Baby-BIM, and both interventions improved hand development. Infants commencing intervention at <6 months corrected age had greater improvements in hand function.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
