Rationale: The soles are the last area to develop creases. At 28 weeks, they are smooth; by 40 weeks, they are fully creased. | Observation | Score | | :--- | :--- | | No recoil (arm remains extended) | 0 | | Slow or partial recoil (< 90°) | 10 | | Complete and brisk recoil (≥ 90°) | 20 |

If the infant has clinical signs of intrauterine growth restriction (weight < 10th percentile, head sparing, wasted appearance) or the mother had documented placental insufficiency, subtract 1 week from the calculated GA. This is because growth-restricted infants appear more mature neurologically and physically than their true age. Pro-tip: The official PDF scoring sheet includes a visual chart or nomogram to avoid manual division, but the formula above is standard. Interpreting Results and Clinical Correlation | Capurro GA (weeks) | Clinical Category | | :--- | :--- | | < 34 | Very preterm / Moderate to late preterm | | 34 – 36 | Late preterm | | 37 – 38+6 | Early term | | 39 – 40+6 | Full term | | 41 – 41+6 | Late term | | ≥ 42 | Post-term | capurro edad gestacionalpdf

Rationale: Skin changes dramatically with maturation. Preterm infants (24-34 weeks) have smooth, gelatinous skin. By term, the epidermis thickens and cracks appear. | Observation | Score | | :--- | :--- | | Flat, shapeless, little to no cartilage | 0 | | Incurved anthelix, soft cartilage that springs back slowly | 10 | | Well-defined anthelix, firm cartilage that springs back immediately | 20 | Rationale: The soles are the last area to develop creases

While obstetric ultrasounds provide the most accurate antenatal dating, millions of infants worldwide are born without reliable last menstrual period (LMP) data or first-trimester sonography. In these cases, clinicians must turn to postnatal physical and neurological maturity assessments. Among the various scoring systems developed over the past 50 years—including the Dubowitz, Ballard (and its New Ballard Score), and Eregie methods—one system stands out for its simplicity, speed, and validation in diverse populations: .
