Postural development in very low birth weight and normal birth weight infants

Area of Science:

• Developmental Pediatrics
• Neonatology
• Neurology

Background:

• Very low birth weight (VLBW) infants exhibit distinct neuromotor characteristics, including lower muscle tone and increased extensor tone.
• Early identification of neuromotor delays is crucial for timely intervention in high-risk infant populations.

Purpose of the Study:

• To evaluate the utility of Vojta's postural responses in assessing neuromotor development in VLBW infants.
• To investigate the association between early postural reactions and later locomotor development in VLBW infants.

Main Methods:

• Applied Vojta's seven postural responses to 68 VLBW infants and 28 healthy normal birth weight infants.
• Infants were assessed at 37-40 weeks postmenstrual age.
• Locomotor development was assessed using the Griffiths Mental Developmental Scale at 12 and 18 months corrected age.

Main Results:

• Significant differences in postural reactions were observed between VLBW and normal birth weight infants.
• Poor head and trunk righting at four months corrected age in VLBW infants correlated with less developed locomotion at 12 and 18 months.
• Five of Vojta's postural responses proved effective for neurological assessment in high-risk infants.

Conclusions:

• Vojta's postural responses can identify neuromotor maturation delays in VLBW infants early in life.
• These early delays predict later challenges in locomotor development, highlighting the long-term impact.
• Vojta's method is a valuable tool for the neurological assessment of high-risk infants.
