Document Summary
Are reflexes that normally appear in infancy and disappear as a child grows and develops control over these reflexes. Primitive reflexes can reappear when neurological conditions cause dysfunction in specific locations of the central nervous system. Two primitive reflexes relevant to tbi are decorticate and decerebrate postures. See the video clip posted on owl to view these postures. Recall the direct and indirect motor control discussed in the stroke session. Is a distinctive body posture following severe damage to corticospinal tract. Recall an umn lesion to this spinal tract causes increased tone in antigravity muscles. Thus, the legs are extended and the upper extremities are flexed. Is a distinctive body posture following severe damage to brainstem. The legs remain extended and the arms become extended as well. We will not bother with the detailed explanation of why the arms become extended.
