Early physical therapy effects on the high-risk infant: a randomized controlled trial
Insights
Early physical therapy did not improve outcomes for high-risk infants. Infants with very low birth weight (less than 750 g) showed developmental delays regardless of treatment.
Area of Science:
- Neonatal care
- Pediatric physical therapy
- Developmental pediatrics
Background:
- Infants at risk for neurologic sequelae require interventions to prevent handicaps.
- Early detection and management are crucial for optimizing developmental outcomes.
Purpose of the Study:
- To assess the effects of early physical therapy on high-risk infants.
- To evaluate the impact of early intervention on preventing or minimizing future handicaps.
Main Methods:
- Prospective, randomized controlled trial of 134 infants from Montreal NICUs.
- Infants stratified by prognosis and birth weight, randomly assigned to early physical therapy or conventional care.
- Outcomes assessed at 12 months by independent evaluators: neurologic status, motor/overall development, physical growth.
Main Results:
- No statistically significant differences in outcomes between early physical therapy and control groups at 12 months.
- Infants weighing < 750 g at birth showed significant growth and developmental delays irrespective of group.
- The investigated early physical therapy program was not effective in altering motor development patterns.
Conclusions:
- Early physical therapy, as implemented, did not demonstrate efficacy in improving outcomes for high-risk infants.
- Very low birth weight remains a significant predictor of developmental delays.
- Further research may be needed to identify effective interventions for this population.
Abstract:
A prospective, randomized, controlled trial was conducted to assess the effects of early physical therapy on infants at risk for neurologic sequelae and to evaluate the impact of such early treatment on the prevention or minimization of future handicaps. A cohort of 134 infants who had received care in two Montreal inborn neonatal intensive care units was identified prospectively. Infants were stratified according to prognosis and birth weight and were randomly assigned to either an experimental or control group. Babies assigned to the experimental group received early physical therapy, whereas those allocated to the control group received conventional follow-up care. Outcome measures were administered by independent evaluators at 12 months and included measures of neurologic status, motor and overall development, and physical growth. No statistically significant differences on any of the measured outcomes at 12 months were found between the experimental and control groups. Infants weighing less than 750 g at birth, regardless of group assignment, consistently demonstrated significant delays in their growth and development when compared with their heavier peers. The early physical therapy program investigated in this study was not efficacious in altering the pattern of motor development in those high-risk infants participating in the trial.
