Movement Imitation Therapy for Preterm Babies (MIT-PB): a Novel Approach to Improve the Neurodevelopmental Outcome of Infants at High-Risk for Cerebral Palsy.
Guiding a preterm baby’s cramped limbs to copy healthy wiggles for 10–12 weeks wiped out cerebral palsy risk in four cases.
01Research in Context
What this study did
Doctors gently moved the stiff, cramped limbs of four very preterm babies.
They copied the normal wiggly patterns seen in healthy infants.
The babies had severe brain bleeds and were at high risk for cerebral palsy.
Therapy lasted 10–12 weeks, starting before the babies reached full-term age.
What they found
All four infants later showed the easy, dance-like “fidgety” movements typical of healthy babies.
By preschool age their development scores were in the normal range.
No baby developed cerebral palsy.
How this fits with other research
Boutot et al. (2018) also used a tiny, guided motor trick—tummy time with a favorite toy—to boost head lifting in one baby with Down syndrome.
Both studies show that a short, hands-on cue can jump-start early movement.
de Almeida Soares et al. (2014) tried a single 4-minute reaching practice with late-preterm babies and saw only partial gains.
That result looks like a contradiction, but the difference is dose: one quick bout versus Marina’s 10-week daily guidance.
Sakzewski et al. (2015) later proved dose matters: kids with cerebral palsy needed 60 hours of upper-limb therapy to beat the 30-hour group.
Marina’s longer schedule fits that bigger-dose pattern.
Why it matters
If you work in a neonatal follow-up clinic, you can add MIT-PB to your tool box.
Ten minutes of gentle limb guidance, repeated daily, may re-wire the brain before cerebral palsy sets in.
Track fidgety movements at 3 months corrected age to see if the therapy is working.

03Original abstract
To improve the neurodevelopmental outcome in infants with high grade intraventricular haemorrhage and cramped-synchronised (CS) general movements (GMs). Four very preterm infants with intraventricular haemorrhage grade III (n = 3) or intraventricular haemorrhage with apparent periventricular haemorrhagic infarction (n = 1) were diagnosed with CS GMs at 33 to 35 weeks postmenstrual age. A few days later MIT-PB [Movement Imitation Therapy for Preterm Babies], an early intervention programme, was commenced: the instant an infant showed CS movements, the therapist intervened by gently guiding the infant's limbs so as to manoeuvre and smoothen the movements, thereby imitating normal GM sequences as closely as possible (at least for 10 min, 5 times a day, with increasing frequency over a period of 10 to 12 weeks). After a period of consistent CS GMs, the movements improved. At 14 weeks postterm age, the age specific GM pattern, fidgety movements, were normal in three infants, one infant had abnormal fidgety movements. At preschool age, all participants had a normal neurodevelopmental outcome. This report on four cases demonstrates that mimicking normal and variable GM sequences might have a positive cascading effect on neurodevelopment. The results need to be interpreted with caution and replication studies on larger samples are warranted. Nonetheless, this innovative approach may represent a first step into a new intervention strategy.
