Midbrain or cortical reflexesNe

Neck on body

• Supine, fully turn to one side

• Body follows/Segmental rolling: Shoulder, trunk, pelvis, LE

• Maintains head/body alignment; initiates rolling aka first ablation effort

Body on body

• Supine; flex one hip & knee towards the chest and hold briefly

• Segmental rolling of the upper trunk to maintain alignment

• Trunk or spinal rotation

Body on head

• Allow to contact supporting surfaces

• Maintaining head in midline/ attempts to right the head vertically

• Vertical righting of the head in preparation for standing and walking

Optic Labyrinthine

• Vertically supported i space, swing body away from vertical position

• Child attempts to keep upright position

• Maintain or establish head in upright position

Protective Extension

• Quick displacement of trunk in downward direction while held

• Allow accurate placement of LE in anticipation of a surface

Parachute reflex

• Quick displacement of trunk while sitting in forward, sideward or backward direction

• Forward: sudden extension of the UE, hand opening and neck extension

• Sideward: Sudden extension and abduction to the side

• Backward: Backward arm extension or extension to one side

• Allows accurate placement of upper extremity in anticipation of supporting surfaces to prevent fall

• Supports body for unilateral use of opposite arm

• Facilitates spinal rotation
