1. Correct. The predominant position in the United States for physician-attended births is the lithotomy position. This position requires a woman to be in a reclined position with her legs in stirrups. Gravity has little effect in this position.
2, 3, 4. Incorrect. Kneeling, sitting, and walking help to align the fetus with the pelvic outlet and allow for gravity to assist in fetal descent.
