General movements and head magnetic resonance imaging to predict cerebral palsy in preterm and low birth weight infants.
Yuu Uchio, Naoko Shima, Tetsuo Ikai
PMID 40895758WHAT IT FOUND
In 154 very-low-birth-weight infants, abnormal head MRI plus definitely abnormal general movements flagged 92.9% of infants who had cerebral palsy and correctly excluded 97.9% who did not.
Alone, each was less accurate.
Key findings
01Abnormal head MRI combined with definitely abnormal general movements flagged 92.9% of infants with cerebral palsy and did not flag 97.9% of infants without cerebral palsy.
02Mildly or definitely abnormal general movements flagged 100% of infants with cerebral palsy and did not flag 37.9% of infants without cerebral palsy.
03Definitely abnormal general movements alone flagged 28.6% of infants with cerebral palsy and did not flag 95.0% of infants without cerebral palsy.

What it does not show
Cerebral palsy diagnoses were made by age 2 years, so some infants classified as non-cerebral palsy may later be diagnosed with cerebral palsy or other developmental disabilities. The study was single-centre and retrospective, and many infants were excluded because they had chromosome abnormalities, malformation syndromes or neurological disorders, died, lacked general movement or MRI evaluation, or were not followed up after transfer or relocation. Only 14 infants had cerebral palsy, so the accuracy estimates depend on a small number of cases. General movement assessments were made from stored videos by two physiotherapists, with consensus when they differed; the paper does not describe blinding to later diagnosis. Head MRI was classified only as abnormal or not abnormal, not by the specific brain finding. The study tested prediction, not whether earlier rehabilitation changes outcomes.

The easy way to misread this
Do not read the high combined accuracy as evidence that early physiotherapy improves outcomes. This was a retrospective record review in 154 infants, and only 14 had cerebral palsy diagnosed by age 2.
