The Ballard Maturational Assessment , Ballard Score , or Ballard Scale is a technique commonly used for gestational age assessment. It provides scores for a variety of criteria, the sum of all that is then extrapolated to fetal gestational age. These criteria are divided into physical and neurological criteria. This score allows for an estimated age in the range of 26 weeks to 44 weeks. New Ballard Score is an extension of the above to include a very premature baby that is up to 20 weeks.
Scores depend on the intra-uterine changes that the fetus experiences during its maturation. Whereas the neurological criterion depends mainly on the muscle, which is physically dependent on anatomical changes. Neonates (less than 37 weeks) are in a state of physiological hypotonia. This tone increases during the fetal growth period, which means more preterm infants will have lower muscle tone.
It was developed in 1979.

Scoring
Each of the above criteria is scored from 0 to 5, in the original Ballard Score. The scores then range from 5 to 50, with appropriate gestational age being 26 weeks and 44 weeks. An increase in score by 5 increases the age of 2 weeks. The New Ballard score allows a score of -1 for criteria, thus allowing a negative score. Possible scores then range from -10 to 50, the pregnancy range extending for up to 20 weeks. (The simple formula to come directly to the age of the Ballard Score is Age = ((2 * score) 120))/5
