DECORTICATE RIGIDITY PDF

The shoulders are adducted tightly to the sides while the elbows, wrists, and fingers are flexed or clenched into fists. The legs are extended or straightened, internally rotated or feet turned inward and plantarflexed. Medically, this form of rigidity is the indicative of a corticospinal tract lesion at the level of the diencephalon above the superior colliculus. Decerebrate Rigidity Decerebrate posturing or rigidity is an involuntary extension posture of both upper and lower extremities with head and trunk arched back. While legs are fully extended and stiffened with feet internal rotation and plantarflexed. The patient is usually severely rigid, with the teeth clenched.

Medically, this form of rigidity is the indicative of a corticospinal tract lesion at the level of the diencephalon above the superior colliculus. Decerebrate Rigidity Decerebrate posturing or rigidity is an involuntary extension posture of both upper and lower extremities with head and trunk arched back.

While legs are fully extended and stiffened with feet internal rotation and plantarflexed. The patient is usually severely rigid, with the teeth clenched. This stiffness is usually both sides but can be unilateral, can be in the arms only or can be intermittent. Medically, decerebrate rigidity is an indicative of a corticospinal tract lesion at the level of brainstem between the superior colliculus and vestibular nucleus.

Opisthotonus This form of an abnormal posture is the severely rigid hyperextended posture with a strong and sustained contraction of the extensor muscles of the neck and trunk.

Sometimes, proximal limbs extensor muscles are also involved. Common causes of abnormal posturing or severe rigidity Traumatic brain injury.

The legs are extended and internally rotated, with plantar flexion of the feet. This posture may occur unilaterally or bilaterally. See Recognising decorticate posture. Decorticate posture usually results from stroke or head injury. It may be elicited by noxious stimuli or may occur spontaneously. The intensity of the required stimulus, the duration of the posture, and the frequency of spontaneous episodes vary with the severity and location of cerebral injury. Although a serious sign, decorticate posture carries a more favourable prognosis than decerebrate posture.

Decorticate Posturing

Causes[ edit ] Posturing can be caused by conditions that lead to large increases in intracranial pressure. Decerebrate and decorticate posturing can indicate that brain herniation is occurring [7] or is about to occur. In herniation syndrome, which is indicative of brain herniation, decorticate posturing occurs, and, if the condition is left untreated, develops into decerebrate posturing. Decorticate[ edit ] Decorticate posturing, with elbows, wrists and fingers flexed, and legs extended and rotated inward Decorticate posturing is also called decorticate response, decorticate rigidity, flexor posturing, or, colloquially, "mummy baby".
