When assessing a newborn with no arms or other deformities, how are the related sections scored?

This is an important question, since the same principle can be applied to a child born frank  breech, with genu recurvatum, or with cryptorchidism. In any and all situations where the criterion cannot be performed, it is crucial that the rest of the assessment be performed, and that a score similar to the others be assigned. If it is skipped or given a zero value, the gestational assessment will result in a falsely low score, and hence in a falsely low gestational age.
