prone posture

Etymology: L, pronare, to bend forward, ponere, to place
a posture assumed by lying flat with the face forward in response to certain disorders of the spine or viscera.


(pos'chur) [Italian postura, fr. L. positura, fr. ponere, to place]
Attitude or position of the body.

coiled posture

Posture in which the body is on one side with legs drawn up to meet the trunk. It is used sometimes during lumbar punctures.

decerebrate posture

A rigid posture of stiff, extended arms, pronated forearms, and exaggerated deep tendon reflexes. It is a posture of a patient who has lost cerebral control of spinal reflexes, usually as a result of an intracranial catastrophe.

decorticate posture

A rigid posture of flexed arms, clenched fists, and extended legs. It is the characteristic posture of a patient with a lesion at or above the upper brainstem.
Synonym: decorticate rigidity

dorsal rigid posture

Posture in which the patient lies on the back with both legs drawn up. This is a position that is maintained by some patients suffering the pain of peritonitis.

hyperlordotic posture

Increased lumbar lordosis without compensation in the thoracic or cervical spine. It is a component of the condition colloquially referred to as sway-back. See: illustration

kyphosis-lordosis posture

A stance in which the pelvis is tilted forward, causing hip flexion, increased lumbar lordosis, and thoracic kyphosis.

modified plantigrade posture

A standing position with the lower extremities on the ground and the upper extremities bearing weight on a table or other surface. The body weight is stabilized on all four extremities. This posture is used developmentally and in physical therapy to prepare for independent standing and gait.

open posture

Positioning the body with the torso leaning toward the person being addressed, the arms at one's sides, and the chest, abdomen, and lower extremities easily seen. This form of body positioning during communication implies that one is actively listening and emotionally available to the client or patient. By contrast, a closed posture (in which one leans back, crosses one's arms on the chest and crosses the legs) implies that a person is less receptive to the other person.

orthopnea posture

Posture in which the patient sits upright, hands or elbows resting upon some support; seen in asthma, emphysema, dyspnea, ascites, effusions into the pleural and pericardial cavities, and congestive heart failure.

orthotonos posture

Posture in which the neck and trunk are extended rigidly in a straight line; seen in tetanus, strychnine poisoning, rabies, and meningitis.

prone posture


semireclining posture

Posture used instead of lying supine, by patients who are short of breath, e.g., because of heart failure.

slouched posture

Swayback posture.

standard posture

The skeletal alignment accepted as normal; used for evaluating posture. There is equilibrium around the line of gravity and the least amount of stress and strain on supporting muscles, joints, and ligaments. From either the front or the back, a plumb bob would bisect the body equally. From the side, a plumb bob would be anterior to the lateral malleolus and the axis of the knee, posterior to the axis of the hip and the apex of the coronal suture, and through the bodies of the lumbar vertebrae, the tip of the shoulder, the bodies of the cervical vertebrae, and the external auditory meatus.

swayback posture

A relaxed stance in which the pelvis is shifted forward, resulting in hip extension, and the thorax is shifted backward, resulting in an increased thoracic kyphosis and forward head.
Synonym: slouched posture
