Developmental Medicine & Child Neurology

• Early brain injury causing spastic cerebral palsy results in fewer independent joint movements in infants.
• Baby Observational Selective Control AppRaisal (BabyOSCAR) score at 3 months depends on limbs affected by early brain injury.
• BabyOSCAR scores at 3 months correlate with Gross Motor Function Classification System level at ≥2 years.
• BabyOSCAR has excellent interrater reliability.
• BabyOSCAR, scored with a 1-minute video recording, has good to excellent test–retest reliability.

Selective motor control at 3 months of age can be quantified by observing spontaneous movements in supine for 1 minute using the BabyOSCAR. The BabyOSCAR score represents the number of joints across the body that demonstrated independent movement during the minute of observation. This score is strongly correlated with gross motor function (GMFCS) at 2 or more years of age.

• Developmental age seemed most predictive of non-response to submandibular botulinum neurotoxin A injections.
• Non-response to concurrent submandibular and parotid injections was best predicted by tongue protrusion and number of previous injections.
• Multivariable prediction models including these clinical characteristics were unable to discriminate well.
• Predictors differed when non-response was defined using alternative outcome measures.
