If you can't find a specific PDF but need the information, here are the general steps for assessing gestational age with the Ballard (Capurro) score:
Neurological Maturity (Score 0-5 for each of 6 items):
The scores from both sections are added to estimate gestational age. This method is quite accurate but requires practice to perform consistently.
It looks like you are asking for a social media or blog post regarding the "Capurro" method for estimating gestational age (often searched as "Capurro edad gestacional pdf" by Spanish-speaking healthcare students).
Below are two options: a professional/scientific post (for LinkedIn or a medical blog) and an educational post (for Instagram, Facebook, or a nursing/med student group).
The examiner flexes the newborn’s arm for 5 seconds, then releases it. | Recoil response | Points | |----------------|--------| | No movement | 0 | | Slow, incomplete | 2 | | Brisk, complete | 4 |
Maximum total score: 8+8+8+8+4 = 36 points.
The Capurro method evaluates four physical signs and one neurological sign. Each sign receives a score, and the total is converted into weeks of gestation.
After summing the points, use the following linear regression formula (Capurro et al., 1978):
Gestational age (weeks) = 25.0 + (Total score × 0.35)
Alternatively, use this simplified table:
| Total score | Gestational age (weeks) | |-------------|-------------------------| | 10 | 28.5 | | 14 | 30.0 | | 18 | 31.5 | | 22 | 33.0 | | 26 | 34.5 | | 28 | 35.0 | | 30 | 35.5 | | 32 | 36.0 | | 34 | 37.0 | | 36 | 38.0 |
Note: For scores below 10 or above 36, the method loses precision. Always compare with maternal dates or ultrasound. capurro edad gestacionalpdf

document.getElementById("result").innerHTML = "Estimated Gestational Age: " + gestationalAge + " weeks";

This example provides a very basic illustration. A real-world application would require more detailed scoring systems and integration with a backend or database for storing reference data. Additionally, developing a complete feature would involve considerations for user interface design, user experience, and technical implementation details based on your specific requirements.
Capurro Method is a clinical standardized system used in neonatology to estimate the gestational age
of a newborn by evaluating specific physical and neurological characteristics. Originally simplified by Dr. Haroldo Capurro in 1980 from the Dubowitz scale, it remains a vital tool in Latin American medical practice for determining neonatal maturity when prenatal ultrasound data is unavailable or unreliable. Redalyc.org Core Components of the Capurro Test The method is typically divided into two versions: (includes 2 neurological and 4 physical signs) and (the most common version, focusing on 5 physical signs). ResearchGate The five primary physical parameters assessed are: Skin Texture:
Ranges from very thin/gelatinous to thick with deep wrinkles/parchment-like peeling. Ear Shape (Pinna): Evaluates how the upper edge of the ear is curved. Mammary Gland Size: Measured in millimeters (e.g., non-palpable vs. >10mm). Nipple Formation:
Checks for the presence and diameter of the areola and its border. Plantar Creases: Assessment of the wrinkles on the soles of the feet. s1e181b62664a5fde.jimcontent.com The Formula for Calculation
To find the gestational age in days, the individual scores for each parameter are totaled and applied to the following standard formula: Gestational Age (weeks) Total Score
Gestational Age (weeks) equals the fraction with numerator 204 plus Total Score and denominator 7 end-fraction Note: The constant is used for the physical-only "Capurro B" method. s1e181b62664a5fde.jimcontent.com Clinical Interpretation
Once calculated, newborns are categorized into five basic parameters: Post-term: 42 weeks or more. Full-term: 37 to 41 weeks. Mildly Preterm: 35 to 36 weeks. Moderately Preterm: 32 to 34 weeks. Extremely Preterm: Less than 32 weeks. s1e181b62664a5fde.jimcontent.com Comparative Accuracy and Limitations
Recent studies comparing the Capurro method to the "gold standard" of first-trimester ultrasound indicate several key findings: Overestimation/Underestimation:
Capurro tends to overestimate gestational age in babies under 39 weeks and underestimate it in post-term infants. Repositório Institucional da UFBA Reliability:
While highly useful in clinical settings where ultrasound is unavailable, research suggests that when first-trimester ultrasound data (crown-rump length) is available, it should remain the primary method for determining age due to the clinical variability of physical assessments. Specificity:
The method shows high specificity (approx. 75.5%) but may have lower sensitivity compared to modern imaging for certain risk classifications.

While advanced technology like prenatal ultrasound is the gold standard for dating a pregnancy, medical professionals often find themselves in situations where such data isn't available. In these moments, clinical methods like the Capurro method
become vital tools for assessing a newborn's maturity immediately after birth. What is the Capurro Method?
Developed as a practical alternative for resource-limited settings, the Capurro method uses a specific set of physical and sometimes neurological signs to estimate a newborn's gestational age. It is particularly useful when the mother's last menstrual period (LMP) is uncertain and no early ultrasound was performed. How Does it Work?
The assessment primarily focuses on five somatic (physical) characteristics: Skin Texture:
Ranging from very thin and gelatinous to thick with deep cracks. Ear Shape: The degree of incurvation of the ear's upper edge (pina). Mammary Gland Size: Measuring the palpable nodule. Nipple Formation: Observing the diameter and the appearance of the areola. Plantar Folds: Looking for creases on the soles of the baby's feet. Calculating the Age To find the gestational age in days, a constant (usually
) is added to the sum of the points from these characteristics. This total is then divided by to determine the age in weeks. (Score + 204) / 7 = Gestational Age (weeks) Accuracy and Clinical Use
While it is a cornerstone in many maternity hospitals, studies show that Capurro can sometimes overestimate the age of infants born before 39 weeks or underestimate it in post-term babies. Despite these variations, it remains a highly effective tool for identifying Small for Gestational Age (SGA) newborns, showing high specificity in clinical settings. Estimating gestational age and its relation - SciELO
Step 1: Sum the scores from the five items (maximum total = 30+20+15+15+20 = 100).
Step 2: Apply the linear formula
[
\textGestational age (weeks) = \frac\textTotal Score + 2047
]
Example: Total score = 80
80 + 204 = 284 → 284 / 7 = 40.57 weeks (approximately 40 weeks + 4 days).
Step 3: Adjust for IUGR (Very Important!)
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. Neurological Maturity (Score 0-5 for each of 6 items) :
Pro-tip: The official PDF scoring sheet includes a visual chart or nomogram to avoid manual division, but the formula above is standard.
The Capurro method evaluates a newborn based on the following physical and neurological criteria:
Neurological Maturity:
Each feature is scored, and the total score corresponds to an estimated gestational age.

Struggling to memorize the Capurro scale for your neonatal rotation? You are not alone! 🩺👶
Many of you have been searching for a "Capurro edad gestacional PDF" — so here is the breakdown of what the test actually looks for:
The 5 Physical Signs (Score 0-5 each): 1️⃣ Skin texture (Thick/cracked = more mature) 2️⃣ Ear shape (Curled cartilage = term) 3️⃣ Breast tissue (Nodule >7mm = >37 weeks) 4️⃣ Plantar creases (Soles fully covered = mature) 5️⃣ Skull bones (Firm/closed sutures = late term)
➕ Bonus: If the baby is < 32 weeks, add the neurological sign (Scarf sign or Heel to ear).
The Math: Total Score + 204 / 7 = Gestational age in weeks!
