First maneuver: fundal grip

While facing the woman, palpate the woman's upper abdomen with both hands. An obstetrician can often determine the size, consistency, shape, and mobility of the form that is felt. The

, they move with the trunk.

Second maneuver: lateral grip

After the upper

has been palpated and the form that is found is identified, the individual performing the maneuver attempts to determine the location of the fetal back. Still facing the woman, the health care provider palpates the abdomen with gentle but also deep pressure using the palm of the hands. First the right hand remains steady on one side of the abdomen while the left hand explores the right side of the woman's

. This is then repeated using the opposite side and hands. The fetal back will feel firm and smooth while fetal extremities (arms, legs, etc.) should feel like small irregularities and protrusions. The fetal back, once determined, should connect with the form found in the upper abdomen and also a mass in the maternal inlet, lower abdomen.

Third maneuver: second pelvic grip or Pawlik's grip

In the third maneuver the health care provider attempts to determine what fetal part is lying above the inlet, or lower abdomen. The individual performing the maneuver first grasps the lower portion of the abdomen just above the

Fourth maneuver: Leopold's first pelvic grip

The last maneuver requires that the health care provider face the woman's feet, as he or she will attempt to locate the fetus' brow. The fingers of both hands are moved gently down the sides of the

toward the pubis. The side where there is resistance to the descent of the fingers toward the pubis is greatest is where the brow is located. If the head of the fetus is well-flexed, it should be on the opposite side from the fetal
