The Tanner scale (also known as the Tanner stages or sexual maturity rating (SMR)) is a scale of physical development as pre-pubescent children transition into adolescence, and then adulthood. The scale defines physical measurements of development based on external primary and secondary sex characteristics , such as the size of the breasts ...
The New Ballard Score allows scores of −1 for the criteria, hence making negative scores possible. The possible scores then range from −10 to 50, the gestational range extending up to 20 weeks. (A simple formula to come directly to the age from the Ballard Score is Age=((2*score)+120)) / 5. Maturity Rating:
An alternative approach to the atlas method just described is the so-called "single-bone method" where maturity scales are assigned to individual bones. [ 7 ] [ 8 ] Here, a selection of bones are given a score based on their perceived development, a sum is totaled based on the individual bone scores, and the sum is correlated to a final bone age.
Most of the time these postnatal changes are normal and can be managed with medication and comfort measures, but in a few situations complications may develop. [1] Postpartum physiological changes may be different for women delivering by cesarean section . [ 2 ]
The first six grades of the scale, grades 1 through 6, are differentiated by the degree of genital masculinization; grade 1 is indicated when the external genitalia is fully masculinized, grade 6 is indicated when the external genitalia is fully feminized, and grades 2 through 5 quantify four degrees of increasingly feminized genitalia that lie ...
A typical five-point grading scale is as follows: Grade 1 is given when the ilium (bone) is calcified at a level of 25%; it corresponds to prepuberty or early puberty . Grade 2 is given when the ilium (bone) is calcified at a level of 50%; it corresponds to the stage before or during growth spurt .
Bishop score, also Bishop's score or cervix score, is a pre-labor scoring system to assist in predicting whether induction of labor will be required. [1] It has also been used to assess the likelihood of spontaneous preterm delivery. [ 2 ]
Maternal drug use occurs when drugs ingested by the pregnant woman are metabolized in the placenta and then transmitted to the fetus. Recent research displays that there is a correlation between fine motor skills and prenatal risk factors such as the use of psychoactive substances and signs of abortion during pregnancy.
