Common examination positions. From Lammon et al., 1995.anatomical position that of the human body standing erect, palms facing forward; it is the position of reference in designating site or direction of structures of the body. The anatomical position for quadrupeds is standing with all four feet on the ground; the difference between animal and human anatomical position leads to confusion among terms indicating position and direction.

The body in the anatomical poisition, showing regions of the body. From Applegate, 2000.batrachian position a lying position of infants in which the lower limbs are flexed, abducted, and resting on the bed on their outer aspects, resembling the legs of a frog.Bozeman's position the knee-elbow position with straps used for support.decubitus position that of the body lying on a horizontal surface, designated according to the aspect of the body touching the surface as dorsal decubitus (on the back), left or right lateral decubitus (on the left or right side), and ventral decubitus (on the anterior surface). In radiology, the patient is placed in either the right or left lateral decubitus position with the beam perpendicular to the long axis of the body.dorsal recumbent position position of patient on the back, with lower limbs flexed and rotated outward; used in vaginal examination, application of obstetrical forceps, and other procedures. See illustration.Fowler's position a position in which the head of the patient's bed is raised 30 to 90 degrees above the level, with the knees sometimes also elevated. See illustration.

Low Fowler's.froglike position batrachian position.knee-chest position the patient rests on the knees and chest with head is turned to one side, arms extended on the bed, and elbows flexed and resting so that they partially bear the patient's weight; the abdomen remains unsupported, though a small pillow may be placed under the chest. See illustration.knee-elbow position the patient resting on the knees and elbows with the chest elevated.lateral position Sims' position.lithotomy position the patient lies on the back with the legs well separated, thighs acutely flexed on the abdomen, and legs on thighs; stirrups may be used to support the feet and legs. See illustration.orthopneic position a position assumed to relieve orthopnea" >orthopnea (difficulty breathing except when in an upright position); the patient assumes an upright or semivertical position by using pillows to support the head and chest, or sits upright in a chair.prone position a position with the patient lying face down with arms bent comfortably at the elbow and padded with the armboards positioned forward.

Prone position. From Lammon et al., 1995.reverse Trendelenburg position a supine position with the patient on a plane inclined with the head higher than the rest of the body and appropriate safety devices such as a footboard.Rose's position one intended to prevent aspiration or swallowing of blood, as from an injured lip: the patient is supine with head hanging over the end of the table in full extension so as to enable bleeding to be over the margins of the inverted upper incisors.semi-Fowler position a position similar to position" >Fowler's position but with the head less elevated.Sims position the patient lies on the left side with the left thigh slightly flexed and the right thigh acutely flexed on the abdomen; the left arm is behind the body with the body inclined forward, and the right arm is positioned according to the patient's comfort. See illustration. Called also lateral position.Sims recumbent position a variant of the position" >Sims position in which the patient lies on the left side in a modified left lateral position; the upper leg is flexed at hip and knees, the lower leg is straight, and the upper arm rests in a flexed position on the bed.Trendelenburg's position the patient is on the back on a table or bed whose upper section is inclined 45 degrees so that the head is lower than the rest of the body; the adjustable lower section of the table or bed is bent so that the patient's legs and knees are flexed. There is support to keep the patient from slipping. See illustration.

A body position used in physical examination to evaluate the genitals and perineum in which the patient lies on the back or sits on the buttocks, bends the knees, abducts the thighs, and draws the heels toward the pelvis. Synonym: butterfly position.

functional position of hand

In making splints for the hand, the position in which the wrist is dorsiflexed 20 to 35°, a normal transverse arch is maintained, and the thumb is in abduction and opposition and aligned with the pads of the four fingers. Proximal interphalangeal joints are flexed 45 to 60°.

This position, a component of the developmental sequence, is used in physical therapy to improve weight bearing and stability through the shoulder girdle. Elbow joint stability is not required, because the joint is not involved.

reclining position

Jackknife position.

recovery position

A position in which the patient is placed on the left side with the left arm moved aside and supported to allow for lung expansion and the right leg crossed over the left. This position affords the unconscious, breathing patient the best protection from airway occlusion or aspiration of fluids into the lungs.
