Abstract
Background
The Hammersmith Infant Neurological Examination is one of several useful tools for
early identification of cerebral palsy; however, cut-off scores for cerebral palsy
do not consistently distinguish infants with hemiplegia from those typically developing.
We hypothesized that use of an asymmetry score, in addition to the assessment's standard
total cutoff score, could remedy this problem in a clinical setting.
Methods
This retrospective study of a neonatal intensive care follow-up program with consistent
clinical use of the Hammersmith Infant Neurological Examination matched infants with
a diagnosis of cerebral palsy to infants without motor delays or evidence of neurodevelopmental
impairments. Groups had same corrected and gestational ages at Hammersmith Infant
Neurological Examination assessment. Asymmetry presence was recorded.
Results
Of 74 infants with cerebral palsy, 28 had quadriplegia, 11 had diplegia, and 35 had
hemiplegia. Median total Hammersmith Infant Neurological Examination and asymmetry
scores for hemiplegia were 57.5 and 10 versus 76 and 0 for those without cerebral
palsy. Sensitivity and specificity to distinguish hemiplegia from typical development
by combining a total Hammersmith Infant Neurological Examination score less than 63
and an asymmetry score greater than 5 were 91.8% and 100%, respectively.
Conclusions
In a clinical setting, combining total Hammersmith Infant Neurological Examination
and asymmetry scores can help providers differentiate infants with hemiplegia from
those typically developing.
